The following detailed description of example implementations refers to the accompanying drawings. The same reference numbers in different drawings may identify the same or similar elements.
Embodiments are directed at an immersive content production system that includes a plurality of displays. Immersive content (e.g., virtual reality content, mixed reality content, augmented reality content, content configured for immersive caves/walls, etc.) may be leveraged as part of a system used by users (e.g., artists, engineers, technicians, directors, and other individuals involved in content production) in order to generate content (e.g., movies, television programming, online or streamed videos, etc.). As described herein, the immersive content production system may also be referred to as simply the content production system or production system.
In one aspect, the immersive content production system presents images in real-time or at interactive frame rates (e.g., 24, 30, 60, 120, or 240 frames per second) to users of the content production system. The images may be presented over immersive devices (e.g., virtual reality goggles and augmented reality glasses) or via an immersive environment, such as an immersive “cave” or one or more immersive “walls” (e.g., a performance area partially or completely surround with image displays). In one embodiment, the immersive environment may include a performance area, such as a stage. The performance area may be partially or completely surrounded by light emitting diode (LED) or liquid crystal display (LCD) display screens. For example, the performance area may include one or more walls and a ceiling of LED display screens enclosing or surrounding the performance area. Alternatively, the performance area may be partially or completely surrounded by projector screens. A set of projectors may additionally be configured to generate images on the projector screens. In some embodiments, the performance area may be partially or completely surrounded by a combination of LED or LCD display screens and projector screens. In some embodiments, the content production system may obtain virtual environment content and display the content on the image displays around the performance area. In this way, a performer/actor in the performance area may appear to be within the virtual environment. In some embodiments, the images displayed by the images displays are primarily background content (e.g., trees, buildings, the sun, etc.).
In various embodiments, the content production system can include one or more cameras usable for capturing a performance being performed by a performer in the performance area. The performance area may be, for example, a movie/television set, stage, stadium, park, etc. During the performance, the content production system may detect the motion and/or positioning of the performer. Such detection may be based on markers or sensors worn by the performer, depth and/or other motion detection sensors of the content production system (e.g., light detection and ranging (LIDAR)), motion capture cameras, etc. For example, an array of depth sensors may be positioned in proximity to and directed at the performance area. For instance, the depth sensors may surround the perimeter of the performance area. In some embodiments, the depth sensors measure the depth of different parts of the performer in the performance area over the duration of a performance. The depth information may then be stored and used by the content production system to determine the positioning of the performer over the performance.
In certain embodiments, a taking camera can be aimed at the performance area may capture the performance of the performer as well as the virtual environment displayed by the image displays (e.g., LED displays) behind the performer. In some embodiments, sensors may be used to determine the position and orientation of the taking camera during a performance. For example, Global Navigation Satellite System (GNSS) based sensors may be attached to the taking camera to determine its position within or relative to the performance area. As another example, other cameras may be directed at the taking camera configured to capture the performance. One or more markers may be attached to the taking camera. During a performance, the other cameras may capture images of the taking camera as the taking camera is moved and/or oriented during the performance. The production system may use the images captured of the taking camera to determine the movement and orientation of the taking camera during the performance. Such information may be used to support the content production process. For example, such information regarding the orientation and movement of the taking camera may be used to determine the distance of the taking camera from the performer over a performance. Based on the orientation and movement (and other attributes such as lens aperture and focal length) of the taking camera, the content production system may adjust the virtual environment displayed by the immersive cave or walls in real-time or at interactive frame rates to correspond to orientation and position of the camera. In this way, images of the virtual environment can be perspective-correct over a performance of the performer.
According to some embodiments, methods, and systems of color calibration and adjustment for a content production system are provided. For example, immersive content (e.g., virtual reality content, mixed reality content, augmented reality content, and the like) can be leveraged as part of a content production system used by users (e.g., artists, engineers, technicians, directors, and other individuals involved in content production) in order to generate content (e.g., movies, television programming, online or streaming videos, and the like). To configure such a content production system, the lighting and color provided by displays surrounding the performance area can be advantageously calibrated and adjusted so that the performers, physical items in the performance area, and virtual items shown on the screen can have a selected lighting and color.
Embodiments described herein provide for applying lighting and or color adjustments made to the virtual environment. Various graphical user interfaces are described that can be used by an operator to make adjustments to color and lighting of virtual environment images, generate virtual stage lights, create attached and unattached green screens, generate two-dimensional (2D) virtual objects (e.g., stickers) and/or trigger virtual effects from a tablet computing device. A light measuring device is also disclosed to determine lighting and color values generated by the displays of the immersive cave/wall. The light measuring device may provide information regarding the measured light and color values to the content production system.
The performance area 102 can be, for example, a movie or television set, a stage, a stadium, a park, or the like. In one aspect, the immersive content production system 100 presents images in real-time or at interactive frame rates to users of the immersive content production system 100 (e.g., performers within the performance area 102). Since the displays 104 surround or partially surround the performance area 102, the immersive content production system 100 can create an immersive environment (also referred to as an immersive “cave” or immersive “walls”) for performances that take place within the performance area 102. In this way, an actor or actress performing within the performance area 102 can appear to be in a virtual environment.
In some embodiments, the displays 104 can include light emitting diode (LED) display screens or liquid crystal display (LCD) display screens. For example, the performance area 102 can include one or more walls of LED or LCD displays 104 enclosing the performance area 102. Alternatively, the performance area 102 can be partially or completely surrounded by projector screens. A set of projectors can be configured to project images on the projector screens. In some embodiments, the performance area 102 can be surrounded by a combination of LED display screens, LCD display screens, and/or projector screens.
According to various embodiments, the displays 104 can have various sizes, and the performance area 102 can also have various sizes. In some embodiments the displays 104 can be 20-40 feet tall, and the performance area 102 can be, for example, between 50-100 feet in diameter. In some embodiments, the displays 104 can include multiple displays 104 that are generally fixed in position and mostly surround the performance area 102, along with additional moveable or mobile displays 104 that can be moved into positions that create an immersive environment that extends completely or almost completely (i.e., 300-360 degrees) around the performance area 102. As an example, in one embodiment, fixed position displays 104 can extend approximately 270 degrees around the performance area 102, while moveable displays 104 can be used to augment the fixed position displays to further extend the immersive environment up to 320 degrees or up to 360 degrees around the performance area. Additionally, while not shown in
A taking camera 112 can be attached to a rig 110 and can be aimed at the performance area 102 to capture the performance of a performer as well as the virtual environment displayed on the displays 104. In some embodiments, sensors can be used to determine the position and orientation of the taking camera 112 during a performance. For example, GPS based sensors (not shown) can be attached to the taking camera 112 to determine its position within or relative to the performance area 102.
In some embodiments, other cameras (e.g., motion capture, and/or alignment cameras 122 discussed below) can be directed at the taking camera 112 and/or configured to capture the performance. One or more markers can be attached to the taking camera 112. During a performance, the other cameras can capture images of the taking camera 112 as the taking camera 112 is moved and oriented during the performance. The immersive content production system 100 can use the captured images of the taking camera 112 to determine the movement and orientation of the taking camera 112 during the performance. Such information can be used to support the content production process. For example, such information regarding the orientation and movement of the taking camera 112 can be used to determine the distance of the taking camera 112 from a performer over a performance. Based on the orientation and the movement (as well as other intrinsic attributes such as lens aperture and focal length) of the taking camera 112, the immersive content production system 100 can adjust the virtual environment displayed by the immersive cave or walls in real-time or at interactive frame rates to correspond to the orientation and the position of the taking camera 112. In this way, images of the virtual environment can be made perspective-correct with respect to the performance of the performer.
In some embodiments, the immersive cave or walls can include one or more lighting elements to provide lighting for performance area 102. For example, the immersive cave or walls can include supplemental LED lights 106 separate from the displays 104 that can light the performance area 102 (including the performer) and create various desired lighting effects. Thus, the LED lights 106 can have the ability to project lighting levels of different intensities and project such light from different locations around the stage. In some embodiments the additional LED lights 106 can be controlled during a performance in order to change the intensity of the lighting of performance area 102 (including the performer).
In some embodiments, additional lighting elements can be created within one or more portions of the various displays 104 that create the virtual environment. For example, instead of depicting the virtual environment in a portion of one or more of the displays 104 surrounding the performance area, that portion of the display 104 can simulate an LED light 108 that illuminates the performance area 102. The immersive content production system 100 can include multiple simulated lights 108. The location of each simulated light 108 on the displays 104 can be selected in order to achieve a desired lighting effect. The selection and placement of simulated lights 108 can be made by a director, lighting technician or other user of the immersive content production system 100, prior to the performance taking place within the performance area 102 and being filmed by the taking camera 112. The number and the location of the simulated lights 108 can be readily adjusted at any time during the performance.
Since the simulated lights 108 are created by the displays 104 and are thus part of the displays 104, such simulated lights 108 are also referred to as “embedded lights” or “virtual lights.” The simulated lights 108 can be in addition to or instead of the supplemental lights 106. In some embodiments, the immersive content production system 100 can include simulated lights 108 without any supplemental lights 106. In some embodiments, the taking camera 112 that is capturing images of the performance area and/or the camera rigs 110 do not include any attached lights. For example, in some embodiments the taking camera 112 does not include a ring of LED lights or other form of lighting for illuminating the performance area 102.
In some embodiments, the immersive content production system 100 can further include one or more depth sensors 120 and/or one or more alignment cameras 122. The alignment cameras 122, also referred to as motion cameras, can capture motions in the performance area 102. During a performance, the immersive content production system 100 can detect the motion and/or the positions and the orientations of the performers within the performance area 102. The detection can be based on markers or sensors worn by a performer, as well as by the depth sensors 120 and/or by the alignment cameras 122. For example, an array of depth sensors 120 can be positioned in proximity to and directed at the performance area 102. For instance, the depth sensors 120 can surround the perimeter of the performance area. In some embodiments, the depth sensors 120 can measure the depth of different parts of a performer in the performance area 102 over the duration of a performance. The depth information can then be stored and used by the immersive content production system 100 to determine the positions of the performer over the course of the performance.
The depth sensors 120 can include a motion-sensing input device. The depth sensor 120 can include a monochrome complementary metal-oxide semiconductor (CMOS) sensor and an infrared projector. The infrared projector can project infrared light throughout the first performance area 102, and the CMOS sensor can measure the distance of each point of reflected infrared (IR) radiation in the performance area 102 by measuring a time it takes for the emitted infrared light to return to the CMOS sensor. Software in the depth sensors 120 can process the IR information received from the depth sensor 120 and use an artificial intelligence machine-learning algorithm to map the visual data and create three-dimensional (3-D) depth models of solid objects in the performance area 102. For example, the one or more depth sensors 120 can receive emitted infrared radiation to generate 3-D depth models of a performer, along with the floor, walls, and/or ceiling of the performance area 102. In one test embodiment, the performance area 102 was surrounded by six to eight Kinect® cameras to capture depth information of objects and performers in the performance area 102.
The alignment cameras 122 can be part of a motion capture system that can track the movement of performers or objects within the immersive content production system 100. The alignment cameras 122 can be used to support alignment of virtual assets and physical assets, as described in more detail below. In some instances, the alignment cameras 122 can be used to track the movement of the taking camera 112 and provide a location of the taking camera to the immersive content production system 100. The immersive content production system 100 can use this information to determine what portion of the displays 104 is to be rendered from the tracked position and the perspective of the taking camera 112.
In
The scenery images 214 can also provide a background for the video content captured by the taking camera 112 (e.g., a visible light camera). The taking camera 112 can capture a view of performance area 202 from a certain perspective. In some embodiments, the taking camera 112 can be stationary, while in some other embodiments, the taking camera 112 can be mounted to a track 110 that can move the taking camera 112 during a performance.
Embodiments of the invention can generate and display perspective-correct images (as rendered from the tracked position and perspective of taking camera 112) onto portions of the surrounding image display walls that are within the field of view (i.e., the frustum) of the taking camera. Areas of the displays 104 outside the field of view of taking camera 112 can be displayed according to a global view perspective. Further details associated with generating and displaying content on displays 104 according to two different perspectives in accordance with some embodiments of the invention are discussed below.
I. Color Correction and Lighting Adjustment
In creating the immersive environment presented on displays 104, immersive content production system 200 can render the portion within the frustum of the taking camera 112 differently than it renders the portion outside the frustum of the taking camera 112. For example, embodiments of the disclosure can render the portion 326 of the displays 104 that corresponds to frustum 318 as perspective-correct images that can update based on movement of the taking camera 112. For example, taking camera 112 can move during a performance as performer 210 moves or to capture the performer from a different angle. As the taking camera 112 moves, portions of the scenery images 214 within the viewing frustum 318 can be updated in accordance with the perspective of the camera. Portion 328 of the displays 104 outside of the frustum 318 can be rendered from a global view perspective and thus display relatively static images that do not change based on the movement of the taking camera 112.
In some embodiments, the images inside the frustum of the taking camera 112 can be at a higher resolution than the images outside the frustum. In some embodiments, the images displayed outside the frustum of the taking camera 112 can be relatively basic scenery images (e.g., blue sky, green grass, gray sea, or brown dirt.) In some instances the scenery images can be completely static. In other instances the scenery images 214 can dynamically change over time providing a more realistic background for the performance in the immersive content production system 200. For example, clouds can move slowly across the displays 104, branches of trees can blow in the wind, etc. to create realistic, life-like effects. Further, the scenery images 214 can dynamically change over time to represent changes in the environment over time.
In some instances, the colors of virtual objects (e.g., the performer 210 or snow cat 310) on a display 104 of the immersive cave or walls may not match or may become unsynchronized with the real world colors of the actors and physical objects within the performance area 102. For example, a performer 210 can be wearing a jacket that appears to be one color in the taking camera 112 and appears to be a different color or shade in the virtual environment. This could be a result of changing lighting patterns, light from the displays illuminating the actors, etc. As a result, content generated from images captured by the taking camera 112 may not appear realistic to viewers due to color discrepancies between the virtual and physical objects.
A set extension can provide an example of the color distortion for an immersive content generation system. For example, a set may have a checkerboard floor that extends into the display that portrays a bigger floor than the physical set. At some point the floor meets up against the LED wall. The LEDs on the wall will light up the real checkerboard floor. The lighting can result in a color mismatch unless the immersive content system is able to color correct the images in the display 104 to smooth out the seam between the physical floor and the virtual floor scenery images.
In order to have the colors of the displayed virtual objects, actors, and physical objects match visually, the content production system 200 may adjust the color of the virtual objects shown on the display in real-time (or at interactive frame rates) based on the color of the actors and physical objects in the earlier images (i.e., frames) of a given performance. In various embodiments, the technical supervisors and directors can view the images from the taking camera 112 via one or more monitors and detect the color mismatch.
More specifically, the content production system 200 may automatically or periodically receive input from a user to generate a set of three-dimensional (3D) volumes, such as volume 430 shown in
In an example, if a performer is standing in the middle of the performance area surrounded by displays showing a virtual world with Greek columns around the performer (e.g., 12 columns surrounding the performer). Each one of the columns can have a color correction capsule volume fully enclosing just that one column. The immersive content system could be running 12 different color corrections operations. Using a brute force method, the system could render the whole screen including the entire circle of LEDs 12 times over to account for all 12 of those color correction volumes. Using the techniques disclosed herein, the display area can be segmented up into multiple grid zones with each of the columns occupying a number of grids (e.g., three zones wide by ten zones tall). Whenever the system renders one of those grid zones, the system need only apply the color corrections for volumes that are occupied as grid zones. So now the system can apply all 12 of those color corrections in parallel. This process of color correction can be done in near real-time, with the color correction process being completed in a few milliseconds.
During a performance, the content production system may perform a tiled, deferred color correction pass that handles multiple individual 3D color correction volumes simultaneously, bins the volumes into two-dimensional (2D) tiles in screen space, and then processes the affected pixels in each tile in order according to a per-volume priority factor. For example,
In some embodiments, color correction may be performed by determining one or more color error values or mismatch values between a physical reference target (e.g., a virtual spacecraft 432) in the performance area 102 and a given virtual object. The content production system 200 may iteratively or progressively modify color related attributes for the virtual object until the color error values or mismatch values meet one or more threshold color correction values. As a simple example, the threshold color correction value for a color green may be set at a value of 1. The content production system may continuously color correct the green color for a virtual object until the virtual object's mismatch value is below 1. The iterative process can be a differential render where the color of the selected tiles are compared to a desired color. When the mismatch is above a predetermined threshold, the color is adjusted on the selected tiles until the comparisons are within the predetermined threshold. In various embodiments, a user provides a second input to manual adjust the colors for the selected tiles. In various embodiments, the system detects the colors of the selected tiles and compares the detected colors with a color for the physical object.
In various embodiments, there may be insufficient processing power to make all the color corrections required and thus the corrections can be prioritized. In these cases, the lower priority corrections may not be made.
In some embodiments, the per-volume priority factor for each volume may be assigned via user input. In other embodiments, the per-volume priority factor may be based on one or more criteria or heuristics. For example, the content production system may assign higher per-volume priorities for volumes that take up a larger portion of a given image frame. As another example, the content production system may assign higher per-volume priorities to volumes that contain virtual objects that are moving at least a threshold velocity or that are moving faster relative to other virtual objects. As yet another example, the content production system may assign higher per-volume priorities to volumes that contain virtual objects of certain shapes. For instance, volumes with virtual objects containing humans (e.g., background characters) may be assigned higher per-volume priorities. As yet another example, the content protection system may assign higher per-volume priorities to volumes that are virtually closer to the taking camera. The content production system may determine the closeness of a virtual object based on the virtual depth of the object. As still another example, the content production system may be trained using previously assigned priority factors for various volume shapes and/or virtual object shapes. Based on the training, the content production system may automatically assign per-volume priority factors for volumes in a given performance.
If the entirety of scenery 214 is rendered from the tracked position and perspective of the taking camera 112 to present perspective-correct images across the entirety of surrounding displays 104, in some instances view-dependent lighting artifacts will be present on the physical foreground components within the performance area 102 (e.g., the performers/actors, props, and physical set decorations). As the taking camera 112 moves, the rendered images on the displays 104 update, which can result in a visual discrepancy between the static physical set in the performance area 102 and the virtual assets of the virtual environment rendered by displays 104 on the walls. As a result, light sources (e.g., virtual sun 206) within the virtual environment might appear to move across the performers 210, across the props 212, and/or across various set decorations, just because the taking camera 112 is physically moving. Thus, it might appear that virtual sun 206 moves relative to a performer based on movement of the taking camera when in fact the position of virtual sun 206 relative to the performer should not change.
To mitigate this visual artifact, two separate renderings can be performed in some instances by the content production system of embodiments of the invention when displaying a virtual environment. A method of rendering content onto the displays 104 according to some embodiments of the invention, the two renderings can be performed simultaneously and in real-time. In one rendering, a global view of the virtual environment (including any virtual assets) is rendered independent from the perspective of the taking camera. The global view can include background or scenery images that create much of the virtual or immersive environment that provides context for the one or more performers on stage 102. The global view can also include lighting effects produced from displays outside the frustum of the taking camera 112. Depending on the size of frustum 318, this global view rendering can be displayed on the majority of the display area within the virtual environment.
The system can render the global view from a virtual spherical camera placed at a virtual location within the virtual environment based on predefined criteria. In some embodiments, the placement of the virtual spherical camera can be based on a threshold error value for the lighting of virtual objects within the virtual environment and/or lighting of the physical objects in the performance area. The threshold error value can indicate a minimal acceptable level of visual inaccuracy of the lighting of the objects within the virtual environment and/or performance area. In some embodiments, the images of the virtual environment rendered by in the global-view rendering can remain completely static. In other words, objects within the virtual environment might not move or change in location on the displays 104 over time or during a performance. In other embodiments, objects within the global-view of the virtual environment are not completely static but simply do not update in response to movement of the taking camera 112. Images of the virtual environment generated during the global-view rendering can be used for lighting and reflection purposes onto the physical foreground/performance area.
In another rendering, a portion of the virtual environment is rendered from the location and perspective of the taking camera. The perspective-correct rendering can be completely independent from the global-view render and can include performers, props and background scenery within the frustum (e.g., frustum 318) of the taking camera 112. The perspective-correct rendering represents a portion of the virtual environment and can thought of as a patch that can be displayed on a portion of displays 104. As the global view can be captured by a virtual spherical camera, discrepancies can exist for images displayed on the displays in the background from the spherical camera as compared with images that captured within the frustum of the taking camera. Therefore, a patch can be created to correct the images in the background displays that appear within the frustum of the taking camera. In this way as the taking camera captures the one or more images with actors, props, and background, the background appears to be perspective-correct and do not move abnormally due to movement of the taking camera.
Embodiments of the invention can combine the patch from the perspective-correct rendering with the global-view render to present the virtual environment on the content production system without (or with fewer) undesirable lighting effects. For example, images of the virtual environment can be generated onto displays 104 and updated over the course of a performance so that the perspective of the virtual environment displayed compensates for corresponding changes to the positioning and orientation of the taking camera 112. In some embodiments, rendered content is combined such that the displays 104 display the perspective-correct rendering in the portion of the displays 104 that is viewable by the frustum 318 of the taking camera 112 and the portions of the displays 104 outside of the frustum 318 of the taking camera 112 only include the rendered images from the global-view render.
II. Additional Color Correction Techniques
An objective of the color correction techniques is to produce as many in camera finals as possible. This will reduce the cost of post processing video products. The techniques can be the equivalent to running a 2D and 3D compositing tool (e.g., Nuke) in an interactive environment. The color correction techniques attempt to match the 3D elements in the virtual environment with the real life set pieces that are physically on the set. For example, for a science fiction show, an entire spacecraft may not be built on the set, but just a portion (e.g. a ramp or a cockpit) may be physically constructed. The color correction techniques help match the physical portion with the virtual images of the ship that is presented on the displays to make the video as seamless as possible. The technique can include blending the practical set with digital sets so there is very little to no discrepancies perceptible between the real world environment and the digital environment on the displays.
There can be a few different types of color correction methods. One type can be known as a global color correction. For examples where the entire scene is too dark an operator may want to stop (e.g., camera stops) everything up to increase the exposure by some camera stops, to make the entire scene brighter. Global corrections can be made to an entire virtual works on all the LED walls. For example, the global correction can increase the brightness or make it bluer or make it warmer or make it cooler using color charts.
Color correction can be a very artistic process, and in many cases, the operator can be an artist with over 20 years of experience making color correction adjustments as part of a post-production process. Aspects discussed herein allow for color correction adjustments to be made in real time. There can be some cases where the adjustments can be automated or at least partially automated. For example, an operator may want to adjust the temperature of a group of virtual streetlamps (e.g., turn up all the streetlamps from 5500 kelvin temperature to 6500 kelvin temperature). A script can be used for this type of adjustment.
As described above, there can be color correction objects, color correction volumes, and color correction windows, and sky color correction. For color correction objects, the objects in the virtual environment can be selected by a pointing tool. For example, there may be hundreds of streetlamps requiring the same color correction. The streetlamp can be designated as a color correction object and the color correction controls can be used to change the color or temperature of all the streetlamps.
The color correction volumes are similar to a voxel pic. The color correction volume is a literal volume of the cube. The edges of the color correction volumes can be rounded. The shape of the color correction volumes can be changed. In various embodiments, the volumes can be spherical a cube, a rectangular prism. The 3-D scene can have its own 3-D coordinates and can move right to the step in the scene. The 3-D effects can be complicated because it is projected onto a curved, flat 2-D wall. The 3-D virtual scene has volume and characters can virtually walk around in the images with some depth.
The color correction volume allows for selection of a volume in that 3-D space. For example, it can be an area around where a virtual space ship is parked. If the ship is only a 3-D virtual ship and there is some dirt on the ground around the ship that the operator wants to adjust the visuals, one of these volumes can be used for the ground. In that way, the ground area, and anything within that volume can receive a color correction. Anything outside of the volume would not. In various embodiments, there are other mechanisms for making different shapes to combine these squares or cubes together so there can be a sort of a blobby shape that would roughly cover a ship or some other odd shape. The color correction volume does not need to be spherical or a defined prism.
A color correction window is similar to a virtual stage light or other stage projections. Stage projections can be a 2-D virtual object (e.g., a sticker) that can be displayed over the images on the LED displays. As the taking camera moves around the performance area, the 2-D virtual object stays pointing straight at the taking camera so it does not bend as the camera moves around in the 3-D scenes. The 2-D virtual object stays as the normal to the display or stated otherwise stays flat to the wall. Other 3-D objects in the virtual space can have depth so they are not flat to the wall and can be distorted. By using 2-D virtual objects, the shape of the object does not change based on the position of the camera.
If the camera is locked off, if the camera is not moving, the operator can turn off the low pass system temporarily for the camera. With the camera being fixed there is no wobble. With the motion capture driver temporarily switched off, an operator can even pick the camera off a stand and move it around and the frustum will not move as it will remain locked to its previous location. The operator can detect an area that appears too yellow and the operator may want it to be greener. The color correction window can approach the correction from a 2-D perspective as if the operator was editing a single frame in video. The operator may want to change out one area or cover over one area and blend it out in some way or another. If the camera does not move, the immersive content production system can maintain this parallax trick of ensuring that it is perspective correct-enough to “sell” the trick and still potentially achieve an in-camera final. The color correction window provides that kind of workflow to these artists. Color correction windows are not limited for use with locked off camera, but that can be an obvious use case where the operator can fix something in the scene and make it work for the very specific camera perspective through the lens of the camera.
In certain embodiments, upon selection of a point of region of the immersive cave/wall, the content production system may enable a user to select a color and/or lighting values currently associated with the point or region at a given playback time for the virtual scene displayed by the immersive cave/wall. For example, at one minute into the playback of a virtual scene, a region may be associated with the blue color of a virtual sky. The content production system may select the blue color in response to a user selection input. The content production system may then store the color and/or lighting values for the selected point or regions. Thereafter, the user may select another point or region of the immersive cave/wall using the mechanisms and/or in the same manner as previously described. Upon selection, the content production system may modify the color and/or lighting values of the selected another point or region based on the color and/or lighting values of the initially selected point or region.
In some embodiments, the modification of the color and/or lighting values of the selected another point or region may include blend processing. More specifically, the content production system may determine the color and/or lighting values of neighboring or nearby regions surrounding the selected another point or region. Based on the values for the neighboring regions and the values for the initially selected point or region, the content production system may use a blending processing function such that the color and/or lighting values of the selected another point or region may be blended with its surrounding neighbor regions. In various embodiments, the blending processing function can support linear blending. In various embodiments, the blending processing function can support radial or three dimensional blending. In this way, the modification of the color and/or lighting values may appear more seamless to a viewer.
In some embodiments, a user may directly input a particular color and/or lighting value for a selected region. These include, for example, color temperature, hue, intensity, exposure, softness, roundness, saturation, etc.
In some embodiments, modification of the point or region may include selecting one or more individual 3D geometries or meshes of the 3D virtual scene displayed by the immersive cave/wall that correspond to the selected point or region of the immersive cave/wall. In doing so, the modification is made to the virtual objects of the 3D virtual scene. Thereafter, a 2D image is generated based on the modified 3D virtual scene for display on the immersive cave/wall. This is in contrast to other embodiments where the underlying 3D virtual scene is not modified. In those embodiments, a 2D image is first generated from the unmodified 3D virtual scene. Thereafter, the 2D image is modified to adjust for lighting/color.
In certain embodiments, selection of the underlying geometry includes casting a virtual ray from a projector camera origin, through the selected point on the immersive cave/wall and intersecting the ray with geometries existing in the 3D virtual scene displayed by the immersive cave/wall. In other embodiments, the content production system initially casts a ray with the wall geometry to place a reticle in the 3D virtual scene. Thereafter, the content production system may ray cast from the projector camera position through the reticle's 3D position to get the targeted geometry in the 3D virtual scene. In other words, the system would place a reticle on a 3D virtual object in a 3D scene corresponding to the direction and/or orientation of the handheld mechanism. Thereafter, a 2D image would be rendered from the 3D scene including the reticle to be displayed on the immersive cave/wall. This is, in contrast, to the system adding a reticle to a corresponding location on a 2D image displayed on the immersive cave/wall following rendering of the 2D image from the unmodified 3D virtual scene. Note that the ray cast is always from the projector camera position and not from the handheld mechanism position.
In some embodiments, the content production system is configured to cause the immersive cave/wall to display a camera frustum. One benefit of having the reticle live in 3D space (3D virtual scene) exactly on the immersive cave/wall is that the reticle position in 2D space will not change regardless of what projection is used. As such, the reticle as viewed through a frustum would be in exactly the same position as viewed through the projector camera.
III. Virtual Stage Lighting
The LED displays can be used as a light source for the performance area. In the past, a director would request a stage light be set up in a certain area, with a certain size, and a certain color. This would take time for the lights to be assembled, a colored gel to be applied, and cooling to be set up for the hot lights. Virtual Stage Lights (also known as light cards) can emulate physical lights but with much greater flexibility and responsiveness. The virtual stage lights can be controlled through a graphical user interface (GUI) on a tablet computer. For example, the GUI can allow an operator to set up a new light, adjust the location, adjust the size and shape of the light, and adjust various lighting properties (e.g., brightness, color, temperature, etc.)
In various embodiments, the virtual stage lights can emulate a black flag which is an area that is fully dark so the background is not casting light onto the performance area (or actors). In various embodiments, the virtual stage lights can emulate a net which can be a half-light card and a half black flag. This can control the amount of light on the performance area. The virtual stage lights are not just for illumination but can also be used to control reflections. The virtual stage lights can be used to create interesting and unusual reflections on a ship or on a character.
Virtual green screens can be a way of using a 2-D object in order to have a real time way to replace the physical green screen. The green screen can be the fabric that flips down on the set and then actors act against it, not in the context of a 3-D world because it is just green. The green screen is typically replaced in post-production with visual effects.
But in some cases, it may not be possible to achieve an in-camera final for a shot, but it would be undesirable to just make the whole back wall green. Using virtual green screen can provide some of the benefits of controlling the reflections or from the lighting or other projected scene elements displayed on the LED displays except for maybe one section. For example, maybe there is an area around an actor someone with very specific hair. There can be issues with hair and other fine clothing details in general with visual effects compositing. In various embodiments, it may be desirable to mask out a character, for example in a face replacement. In those cases a green light card or a blue light card for a blue screen may also have some digital markers on top of the base color. Instead of taping up a green screen and putting literal “Xs” or “+” signs made out of tape as on a real “green screen” on a set, a virtual green screen can be generated digitally. The virtual green screen can further enhance the ability to get in-camera finals for the rest of the shot but not maybe for one section that is potentially being pinned up.
In the virtual green screen, the operator can adjust lights also. There can still be lighting coming off the virtual green screen that may help with some of the rest of the image. Lights can be combined with green screen so you could either have a green screen on top of or below the lights.
In another case, one stage can have a strong light on one side of the volume and a very dark region on the wall on the other side so it was flaring out on the far wall. It was just making it too bright. So while it was imperfect for the rest of the scene, that particular angle shooting that wall, it was not possible to get an acceptable shot so the operator chose to use green screen for that.
In other examples, there may be no 3-D elements and the operator may just have this wrapped beautiful panosphere view that was captured using a 360 degree camera in a unique location. That scene is being projected on the displays and then the operator can layer light cards and color correction or other real-time creative edits on top of that unwrapped 360-degree image. That lighting effect can be known as a panosphere. The panosphere can receive color, position, and other corrections.
Panosphere is like the sky itself. The sky may be separate from the 3-D scene. The displays may have a layered sky behind it. For example, the scene may have a desert landscape and then the operator has an image of sky. The operator may want to change the position of the sun and color correct the sky or rotate the position of the clouds in the sky separately from the scene.
The scenery images 214 can also provide a background for the video content captured by the taking camera 112 (e.g., a visible light camera). The taking camera 112 can capture a view of performance area 202 from a certain perspective. In some embodiments, the taking camera 112 can be stationary, while in some other embodiments, the taking camera 112 can be mounted to a track 110 that can move the taking camera 112 during a performance.
Embodiments of the invention can generate and display perspective-correct images (as rendered from the tracked position and perspective of taking camera 112) onto portions of the surrounding image display walls that are within the field of view (i.e., the frustum) of the taking camera. Areas of the displays 104 outside the field of view of taking camera 112 can be displayed according to a global view perspective. Further details of associated with generating and displaying content on displays 104 according to two different perspectives in accordance with some embodiments of the invention are discussed below.
In some embodiments, the size and/or shape of a selected region may be altered by the user in real-time or substantially real-time. In some instances, the light/color adjustment element used for selecting a region and/or the selected region itself (used for the purpose of adjusting the lighting of another region) may be referred to as a Lightcard. In some embodiments, a gradient may be selected and applied to a particular region or point. More specifically, two or more colors and/or lighting values may be selected for a gradient to be applied to a region. Thereafter, gradient points may be placed on the region that corresponds to each selected color and/or light value. In response, the system may apply a gradient in which the color and/or lighting values are progressively changed from one corresponding color and/or lighting value to another corresponding color and/or lighting value between two gradient points.
In some embodiments, the lighting and/or color may be applied based on the 3D virtual objects corresponding to the region to which the lighting and/or color values is to be applied. Specifically, the system may determine/account for the 3D virtual object type in applying the color and/or lighting. For example, the color and/or lighting may be applied differently if the corresponding 3D virtual object type is metal as opposed to grass. In some embodiments, the system may determine a boundary between two 3D virtual objects and blend the two virtual objects accordingly. For example, the system may determine that a selected region includes a boundary between a virtual sky and virtual ground. In response, the system may apply a blending technique to make the boundary between the two objects more seamless to a viewer.
IV. Virtual Stage Lights Flow
At block 1010, process 1000 may include receiving a first input from a user indicating a lighting value. For example, the computing device may receive a first input from a user indicating a lighting value, as described above. The input can be received via a pointing device or a lighting capture device as described later. In various embodiments, the first input can be received on a GUI via an application on a tablet computer. In various embodiments, the first inputs can be made via a laptop computer or a desktop computer.

V. Lighting and Color Correction Graphical User Interfaces
In some embodiments, the content production system may enable a user to adjust the color and lighting of the displays 104 in real or substantially real-time (e.g., at interactive frame rates). In some embodiments, the content production system may include a mechanism to enable the user to select a region of the displays 104 for which the color and/or lighting should be adjusted. In certain embodiments, the mechanism may be a tablet or other mobile computing device.
The mobile computing device may present an interface that includes a representation of the immersive cave/wall comprising the displays 104. The representation may be presented as flattened version of the immersive cave/wall. In some instances, mapping data may be stored and leveraged by the content production system to map the flattened representation of the immersive cave/wall presented on the mobile computing device to the curved/cylindrical physical immersive cave/wall. In some instances, the mapping data may be based on a longitudinal and latitudinal mapping system. In some instances, the tablet may be configured to receive input from a user, such as a finger press or combination of finger presses. Based on the location of the finger press received at the tablet screen displaying the immersive cave/wall representation, the content production system may select a corresponding region of or point on the immersive cave/wall.
The GUI may include various layers, windows, screens, templates, or other graphical elements that may be displayed in all, or a portion, of the display. Generally, the GUI may include graphical elements that represent applications and functions of the electronic device. The graphical elements may include icons and other images representing buttons, sliders, menu bars, and the like. The icons may correspond to various applications of the electronic device that may open upon selection of a respective icon. Furthermore, selection of an icon may lead to a hierarchical navigation process, such that selection of an icon leads to a screen that includes one or more additional icons or other GUI elements. The icons may be selected via a touch screen included in the display, or may be selected by a user input structure, such as a wheel or button.
In various embodiments, various input devices can be connected to the tablet computers via either wired or wireless connections (e.g., Bluetooth). For example, a device having a plurality of physical sliders, switches (e.g., fader switches), buttons, etc. can be connected to the tablet computer to provide improved tactile experience.
A touch-sensitive display provides an input interface and an output interface between the device and a user. The display controller can receive and/or sends electrical signals from/to touch screen. The touch screen displays visual output to the user. The visual output may include graphics, text, icons, video, and any combination thereof (collectively termed “graphics”). In some embodiments, some or all of the visual output may correspond to user-interface objects.
The touch screen can include a touch-sensitive surface, sensor, or set of sensors that accepts input from the user based on haptic and/or tactile contact. The touch screen and display controller (along with any associated modules and/or sets of instructions stored in memory of the tablet computer) detect contact (and any movement or breaking of the contact) on the touch screen and convert the detected contact into interaction with user-interface objects (e.g., one or more soft keys, icons, web pages or images) that are displayed on touch screen. In an exemplary embodiment, a point of contact between the touch screen and the user corresponds to a finger of the user.
The touch screen may use LCD (liquid crystal display) technology, LED (light emitting polymer display) technology, or LED (light emitting diode) technology, although other display technologies may be used in other embodiments. The touch screen and the display controller may detect contact and any movement or breaking thereof using any of a plurality of touch sensing technologies now known or later developed, including but not limited to capacitive, resistive, infrared, and surface acoustic wave technologies, as well as other proximity sensor arrays or other elements for determining one or more points of contact with the touch screen. In an exemplary embodiment, projected mutual capacitance sensing technology can be used.
In some embodiments, in addition to the touch screen, a computing device (e.g., a tablet computer or a notebook computer) may include a touchpad (not shown) for activating or deactivating particular functions. In some embodiments, the touchpad is a touch-sensitive area of the device that, unlike the touch screen, does not display visual output. The touchpad may be a touch-sensitive surface that is separate from the touch screen or an extension of the touch-sensitive surface formed by the touch screen.
In some embodiments, the computing device may include a physical or virtual wheel (e.g., a click wheel) as an input control device. A user may navigate among and interact with one or more graphical objects (e.g., icons) displayed in the touch screen by rotating the click wheel or by moving a point of contact with the wheel (e.g., where the amount of movement of the point of contact is measured by its angular displacement with respect to a center point of the wheel). The wheel may also be used to select one or more of the displayed icons. For example, the user may press down on at least a portion of the wheel or an associated button. User commands and navigation commands provided by the user via the wheel may be processed by an input controller as well as one or more of the modules and/or sets of instructions in the memory of the computing device. For a virtual wheel, the wheel and wheel controller may be part of the touch screen and the display controller, respectively. For a virtual wheel, the wheel may be either an opaque or semitransparent object that appears and disappears on the touch screen display in response to user interaction with the device. In some embodiments, a virtual wheel is displayed on the touch screen of a portable multifunction device and operated by user contact with the touch screen. In various embodiments, haptic feedback can be used on the tablet computer when making changes on the user interface.
A contact/motion module may detect contact with the touch screen (in conjunction with the display controller) and other touch sensitive devices (e.g., a touchpad or physical click wheel). The contact/motion module can include various software components for performing various operations related to detection of contact, such as determining if contact has occurred (e.g., detecting a finger-down event), determining if there is movement of the contact and tracking the movement across the touch-sensitive surface (e.g., detecting one or more finger-dragging events), and determining if the contact has ceased (e.g., detecting a finger-up event or a break in contact). The contact/motion module can receive contact data from the touch-sensitive surface. Determining movement of the point of contact, which is represented by a series of contact data, may include determining speed (magnitude), velocity (magnitude and direction), and/or an acceleration (a change in magnitude and/or direction) of the point of contact. These operations may be applied to single contacts (e.g., one finger contacts) or to multiple simultaneous contacts (e.g., “multi-touch”/multiple finger contacts). In some embodiments, the contact/motion module and the display controller can detect contact on a touchpad. In some embodiments, the contact/motion module and controller can detect contact on a click wheel.
The contact/motion module may detect a gesture input by a user. Different gestures on the touch-sensitive surface have different contact patterns. Thus, a gesture may be detected by detecting a particular contact pattern. For example, detecting a finger tap gesture includes detecting a finger-down event followed by detecting a finger-up (lift off) event at the same position (or substantially the same position) as the finger-down event (e.g., at the position of an icon). As another example, detecting a finger swipe gesture on the touch-sensitive surface includes detecting a finger-down event followed by detecting one or more finger-dragging events, and subsequently followed by detecting a finger-up (lift off) event.
In various embodiments, augmented reality or virtual reality controllers (e.g., Google Glass, or Oculus controllers) can be used to select and modify various elements of the virtual environment. Other hand-held pointers and controllers can be used by the operator.

A fine-tuned controller can also be provided for minor adjustments in the longitude of the position of the center of the virtual stage light 1800.
Each virtual stage light can have various size properties defined by using the virtual stage lights panel 1800. A height indicator 1822 can define a height of a virtual stage light. A width indicator 1824 can define a width of the virtual stage light. An aspect ratio lock 1823 can be used to lock the aspect ratio of width to height. With the aspect ratio lock 1823 engaged adjusting either the height or width of the virtual stage light will adjust the other value to maintain the aspect ratio of the virtual stage light.
A color wheel 1826 can allow the operator to select a color value for the virtual stage light. The operator can select a particular color on the color wheel. Alternatively, the operator can select a Hue value 1828, a saturation value 1830, and a luminosity value 1832 (HSV) from the HSV Color Scale. The HSV scale provides a numerical readout of a selected color that corresponds to the color names contained therein. Hue can be measured in degrees from 0 to 360. For instance, cyan falls between 181-240 degrees, and magenta falls between 301-360 degrees. The luminosity value and saturation of a color are both analyzed on a scale of 0 to 100 percent. Most digital color selection interfaces can be based on the HSV scale, and HSV color models are particularly useful for selecting precise colors for virtual stage lights in the display.
Alternatively, the color for the virtual stage lights can be defined using a red, green, blue (RGB) color model. The RGB color model can be based on the color theory that all visible colors can be made using the additive primary colors of red, green, and blue. As the operator adjusts the amount these basic colors, you can create a variety of different colors. The red value 1834, green value 1836, and blue value 1838 can be presented on the virtual stage lights panel 1800 for the selected color.
An opacity slider 1840 can be used to adjust the alpha channel (e.g., how opaque versus transparent) that Lightcard itself is. A gradient scale 1840 illustrates a fine tuned color for a selected color value 1842. A color picker 1844 (e.g., eye dropper icon) allows an operator to match an existing color from other virtual objects for use for a virtual stage light.
A color temperature selector 1846 allows an operator to select a specific color temperature value of the base color (or white color). Color temperature can be described as warmer (orange) or cooler (blue). Color temperature is a way to describe the light appearance provided by a light bulb. It is measured in degrees of Kelvin (K) on a scale from 1,000 to 12,000. A color temperature value 1848 (e.g., 6500 Kelvin) can be entered by the operator. A color temperature slider 1850 can allow for fine tuning the specific color temperature value 1848. The color temperature slider 1850 can be move to the left for warmer values and to the right to colder values.
All of the different ways to change or select a color of the tint of the virtual stage light can be connected together. Therefore, if an operator selects a color from the color wheel 1826 based on the position of the color selector 1842, the red value 1834, green value 1836, and blue value 1838 can be changed based on the selection. In addition, the Hue value 1828, a saturation value 1830, and a luminosity value 1832 (HSV) from the HSV Color Scale will change for the selection. Similarly changing the HSV values can change the red value 1834, green value 1836, and blue value 1838 displayed and the position of the color selection 1842.
The virtual stage lights panel 1800 can allow the operator to select an intensity value 1852, an exposure value 1854, a softness value 1856, and a roundness value 1858 for virtual stage lights. The intensity value 1852 can be a luminous intensity that can be measured in lumens per steradian or candela. The exposure value 1854 defines an amount of light in a scene. The softness value 1856 is another property of light. Soft light is light that tends to “wrap” around objects, projecting diffused shadows with soft edges, whereas hard light is more focused and produces harsher shadows. The hardness or softness of light depends mostly on three features of the source: the size of its surface, its distance from the object, and the thickness of its diffusion material. A large, distant light source with thick diffusion material will produce softer lighting than one that is smaller and closer to the subject, with thinner diffusion material. Here, Softness and Roundness can be used to specify the edge of the Lightcard “shape”—softness larger means it is a more “feathered” edge.
The roundness value 1858 is another property of the virtual stage lights. The roundness value 1858 changes the shape of the light from a square at 0, to rounded corners, to a disk at 1.
The active switch 1860 allows an operator to turn on and off the virtual stage light.
A Lightcard, like a “real life light”, does not change itself when the color pipeline changes. Imagine a real-life lightbulb on set—if a set crew changes what is happening inside of the stage, the costumes, the backgrounds the real-life light does not change and it just keeps shining at the same brightness and the same intensity and color etc. Lightcards are not affected by the color pipeline changes (lens changes, camera body changes, etc.)
A Sticker, on the other hand, can often be used to patch up the scene or something else, and therefore it is used to ‘blend’ elements in the 3D scene. When the lens changes and color interpretation changes as a result it can be desirable for stickers to have those “Color Transforms” applied.
So, Gamut and Display Transform can be used to be specifiable individually. In various embodiment, an operator may choose either a Sticker or a Lightcard and the Gamut/Display decision can be made internally depending on the selection. The selection at creation-time implies an expected workflow if something triggers a change in the color pipeline (e.g., a change in lens or camera body) during a shoot. The sort order selector 1872 can control the “Z-depth” of the various Lightcards so the operator can control which Lightcard drawings on top of other Lightcards that overlap.
Using the image tab 1904, the operator can select one of a plurality of images 1904, as shown in
The virtual stage lights/sticker panel 1900 can provide controls for varying the location and orientation of the virtual stage light and/or sticker on the displays. A longitude positon indicator 1914 can present the current longitude position of a center of the virtual stage light and/or sticker on the display. The operator can adjust the longitude position of the virtual stage light and/or sticker using the virtual longitude controller dial 1916. A fine-tuned controller can also be provided for minor adjustments in the longitude of the position of the center of the virtual stage light and/or sticker.
Each virtual stage light and/or sticker can have various size properties defined by using the virtual stage lights/sticker panel 1900. A width slider 1918 can be used to adjust the width of the virtual stage light and/or sticker. A height slider 1920 can adjust the height of the virtual stage light and/or sticker. An aspect ratio lock 1922 can be used to lock the aspect ratio of width to height. With the aspect ratio lock 1922 engaged adjusting either the height or width of the virtual stage light and/or sticker will adjust the other value to maintain the aspect ratio of the virtual stage light and/or sticker.
The latitude position indicator 1924 can indicate a current latitude position of the center of the virtual stage light and/or sticker on the display. The latitude position of the virtual stage light and/or sticker can be modified using a coarse virtual latitude slider 1926. A latitude position fine-tune controller 1928 can be used to make minor adjustments to latitude for a position of the center of the virtual stage light and/or sticker.
A rotation value 1930 can indicate the current rotation value for the virtual stage light and/or sticker. The rotation controller 1932 can allow an operator to adjust the rotation value 1930 through the virtual adjustment wheel 1932.
A light illuminant portion of the virtual stage light/sticker panel 1900 can allow for adjustment of a color for the virtual stage light and/or sticker. A white/neutral button 1934, a temperature button 1936, and a chromaticity button 1938 can be presented on the virtual stage light panel 1900.
A color wheel 1940 can allow an operator to define a color value for the virtual stage light and/or sticker. The operator can select a particular color selection 1942 on the color wheel. Alternatively, the operator can select a Hue value 1944, a saturation value 1946, and a luminosity value 1948 from the HSV Color Scale. The HSV scale provides a numerical readout of a selected color that corresponds to the color names contained therein.
Alternatively, the color for the virtual stage light and/or sticker can be defined using a red, green, blue (RGB) color model. The RGB color model can be based on the color theory that all visible colors can be made using the additive primary colors of red, green, and blue. The red value 1950, green value 1952, and blue value 1954 can be presented on the display for the selected color 1942.
An opacity slider 1840 can be used to adjust the alpha channel (e.g., how opaque versus transparent) that Lightcard or Sticker is for a selected color value 1942. A color picker 1958 (represented by an eye dropper) allows an operator to match an existing color for use for a virtual stage light and/or sticker.
A color temperature selector 1942 allows an operator to select a specific color temperature value of the base color. A color temperature value 1962 can be entered by an operator. A color temperature slider 1964 can allow for fine tuning the specific color temperature value 1962.
All of the different ways to change the color or the tint of the virtual stage light are connected together. Therefore, if an operator selects a color from the color wheel, the red value 1950, green value 1952, and blue value 1954 will be represented for the selection. In addition, the Hue value 1944, a saturation value 1946, and a luminosity value 1948 (HSV) from the HSV Color Scale will change for the selection.
The virtual stage lights/sticker panel 1900 can allow the operator to select an intensity value 1966, an exposure value 1968, a softness value 1970, and a roundness value 1972 for virtual stage lights. The intensity value 1966 can be a luminous intensity that can be measured in lumens per steradian or candela. The exposure value 1968 defines an amount of light in a scene. The softness value 1970 is another property of light. Soft light is light that tends to “wrap” around objects, projecting diffused shadows with soft edges, whereas hard light is more focused and produces harsher shadows. The hardness or softness of light depends mostly on three features of the source: the size of its surface, its distance from the object, and the thickness of its diffusion material. A large, distant light source with thick diffusion material will produce softer lighting than one that is smaller and closer to the subject, with thinner diffusion material.
The roundness value 1972 is another property of the virtual stage lights. The roundness value 1972 changes the shape of the light from a square at 0, to rounded corners, to a disk at 1.
The active switch 1974 allows an operator to turn on and off the virtual stage light and/or sticker. The wrapping switch 1976 allows an operator to wrap the virtual stage light and/or sticker between different displays. The show border switch 1978 allows for showing the border. The color and opacity selector 1980 can allow the operator to select color and opacity or opacity only. The transform switch 1982 can apply a display transform to the virtual stage light and/or sticker. The gamut transform switch 1984 applies a gamut transformation to the virtual stage light and/or sticker. Gamut mapping is the problem of transforming the colors of image or video content so as to fully exploit the color palette of the display device. The sort order selector 1886 can control the “Z-depth” of the various Lightcards/Stickers so the operator can control which Lightcard/Stickers drawings on top of other Lightcards/Stickers that overlap.
The operator can adjust the color, position, and lightning characteristics of the panosphere in a scene using the controls on the panosphere control panel 2000. The panosphere control panel 2000 can include many of the same lighting controls as shown for
The operator can create a new panosphere image file or load a panosphere image file from memory. The name 2002 of the panosphere image file can be displayed.
The operator can adjust the exposure of the panosphere using the exposure slider 2004. The exposure value 2006 can be displayed.
The operator can adjust the saturation of the panosphere using the saturation slider 2008. The saturation value 2010 can be displayed.
The operator can adjust the contrast of the panosphere using the contrast slider 2012. The contrast value 2014 can be displayed.
The operator can adjust the gamma of the panosphere using the gamma slider 2016. The gamma value 2018 can be displayed.
The color gain can be adjusted via a plurality of sliders. The operator can adjust the red color value 2020 of the panosphere using the red color slider 2022. The operator can adjust the green color value 2024 of the panosphere using the green color slider 2026. The operator can adjust the blue color value 2028 of the panosphere using the blue color slider 2030. The operator can adjust the temperature of the panosphere using the temperature slider 2032.
The operator can rotate the panosphere around a center point using the pan wheel 2034. The operator can adjust the tilt of the panosphere using the tilt wheel 2036.
The operator can adjust the height of the panosphere using a coarse height adjustment slider 2038 and a fine height adjustment slider 2040. The height value 2042 can be presented on the display. The operator can invert the movement direction using the invert switch 2044.
A first preview box 2046 can display a preview of a first scene. A second preview box 2048 can display a preview of a second scene. A third preview box 2050 can display a preview of a third scene. The first preview box 2046, the second preview box 2048, and third preview box 2050 provide static and/or animated backgrounds that can be loaded into the immersive content generation system.
A focus edit button 2052 can allow for editing the focus point of the display. The focus view button can display the focus point on the display. These buttons scroll the “focus” of the scroll list on the left hand side (that contains all the possible Panosphere images that can be loaded). An operator can scroll the list to the currently-selected pano image—either the one that is currently being edited or the one that is currently being “viewed” (aka loaded on the walls). It is possible that the currently-being-edited and currently-being-viewed pano selection is the same image (shown in a row in the list of selectable images) or could be different ones. The preload all button 2056 allows various panosphere images to be preloaded. The active switch 2058 allows the panosphere images to activated or de-activated on the immersive content displays. The draw order selector 2060 allows for designation of the order for various images of the panosphere. The panosphere image 2062 displays the color of the panosphere. The fade-to-gray image transition switch 2064 allows for toggling the fading feature on and off.
The operator can adjust the color, position, and lighting characteristics of the panosphere in a scene using the controls on the panosphere control panel 2100. The panosphere control panel 2100 can include many of the same lighting controls as shown for
The operator can create a new panosphere image file or load a panosphere image file from memory. The name 2102 of the panosphere image file can be displayed.
The operator can adjust the exposure of the panosphere using the exposure slider 2104. The exposure value 2106 can be displayed.
The operator can adjust the saturation of the panosphere using the saturation slider 2108. The saturation value 2110 can be displayed.
The operator can adjust the contrast of the panosphere using the contrast slider 2112. The contrast value 2114 can be displayed.
The operator can adjust the gamma of the panosphere using the gamma slider 2116. The gamma value 2118 can be displayed.
The color gain can be adjusted via a plurality of sliders. The operator can adjust the red color value 2120 of the panosphere using the red color slider 2122. The operator can adjust the green color value 2124 of the panosphere using the green color slider 2126. The operator can adjust the blue color value 2128 of the panosphere using the blue color slider 2130. The operator can adjust the temperature of the panosphere using the temperature slider 2132.
The operator can rotate the panosphere around a center point using the pan wheel 2134. The operator can adjust the tilt of the panosphere using the tilt wheel 2136.
The operator can adjust the height of the panosphere using a coarse height adjustment slider 2138 and a fine height adjustment slider 2140. The height value 2142 can be presented on the display. The operator can invert the movement direction using the invert switch 2144.
The A/B and A→B switches can be used for comparing a set of values the an operator has chosen to an alternate set of values. The same A/B switcher can be used on the Color Correction panel as well. The setup is that the operator will get some selection of settings in a way they like it—and then then want to experiment with changing some subset of the edited values, whilst leaving some others the same. They then want to visually compare the two buckets of settings. In effect “they want to ‘A/B’ it”.
For example, an operator can dial in a few values and then the operator can think perhaps both exposure should go up 2 stops and saturation should maybe also go down but a couple of units. The current switch A or B is auto-set to the existing values. The operator can then use A→B to PUSH those current values of all sliders/dials to the “B” set. This would make switching between A and B have no effect since the two contain identical settings. Then while on “B”, they will ‘stop up’ exposure a bit and dial down saturation, say. The operator can then, with a single button, swap all the controls back to the previously saved “A” state, and then back to B, back to A, etc. To flick the settings all together back and forth, usually while looking up at the walls to judge the result of the settings changes. Finally, the operator may decide they prefer A or B, and will stick with that and move onto a new task, or they will adjust some more settings and continue to run comparisons of A (or B) vs their ‘baseline’ (the opposite one, B, or A).
A first preview box 2146 can display a preview of a first scene. A focus edit button 2052 can allow for editing the focus point of the display. The focus view button 2054 can display the focus point on the display. The preload all button 2056 allows various panosphere images to be preloaded. The active switch 2158 allows the panosphere images to activated or de-activated on the immersive content displays. The draw order selector 2160 allows for designation of the order for various images of the panosphere. The panosphere image 2162 displays the color of the panosphere. The use fade to gray image transition 2164 allows for toggling the fading feature on and off.
The detached virtual green screen panel 2200 can display the longitude value 2202 and latitude value 2204 of the virtual green screen. The operator can adjust the latitude value 2202 using the longitude adjustment wheel 2206 and the latitude value 2204 using the latitude coarse adjustment slider 2208 and/or the latitude fine adjustment slider 2210.
The operator can adjust a width value 2212 of the green screen using a width adjustment slider 2214. The operator can adjust a height value 2216 using a height adjustment slider 2218. An aspect ratio lock 2219, if selected, the aspect ratio lock 2219 maintains an aspect ratio of the virtual green screen. If the aspect ratio lock 2219 is selected, a change in width will result in a corresponding change in height and vice versa.
A visible switch 2220 makes the virtual visible on the displays if the visible switch 2220 is activated. The immersive content generation system can generate an outline around the virtual green screen if the outline only switch 2222 is selected. The detached virtual green screen panel 2200 can allow an operator to select the green screen color. In various embodiments, a green screen button 2224, a blue screen button 2226, a black screen button 2228, and a colorless or transparent “green” screen button 2230 can be selected. The detached virtual green screen panel 2200 can present the selected color value image 2232 and a numerical color value 2234. A color value slider 2236 allows for adjustment of the color of the virtual green screen. This can be simply a 0→1 slider that controls the same value from the numerical color value entry box (2234). The operator may want to enter an exact floating point number for the Value of the color, (this is the “V” value from the “HSV” system, by the way), or the operator may just want to slide it.
Pressing color value slider 2232, it pops up a color wheel similar to what you see on the Lightcard panel for setting the RGB/HSV with a circular color wheel type control. This affects the value as well of course. The color wheel and additional “V” can be used by the operator to dial back the intensity of the green or blue color if it is too intense of a green, for instance, and is resulting in too much bright green ‘light spill’ from the walls onto the actors. This can result in more post-production visual effects work needing to happen to remove that effect.
The operator can adjust the opacity of the detached virtual green screen 2200 using an opacity slider 2238.
The detached virtual green screen panel 2200 can also provide various tools for adjusting tracking markers. Tracking markers can be “Xs” or pluses (“+”) that can be displayed on the screen. A show marker switch 2240 allows the markers to be toggled on and off on the display. The operator can adjust the shape of the markers using the shape switch 2242 to switch between an x or a plus markers. The operator can adjust the size of the marker using the size selector 2244. The operator can adjust the thickness of the marker using the thickness selector 2246. The operator can adjust a spacing of the tracking markers using the spacing adjustment 2248. The operator can adjust an offset of the various markers from the virtual green screen by entering an X-offset using the offset-X selector 2250. The operator can enter a Y-offset using the offset-Y selector 2252.
The operator can select at least one of a green color 2254, a blue color 2256, a white color 2258, and a black color 2260 for the tracker. The operator can adjust a value for the tracker using the value slider 2262. The detached virtual green screen panel 2200 can have preset colors for commonly used tracker colors like black or white or green. But an operator may want a ‘less intense green’—so rather than offering full HSV control, which may be done in some embodiments—the detached virtual green screen panel 2200 can display some preset buttons here and add a “Value” only slider to reduce the V of the HSV system. This allows the operator to dial-back the intensity as needed on the tracking markers for the same reasons as described above for the green screen color itself.
The operator can adjust a width value 2310 of the green screen using a width adjustment slider 2314. The operator can adjust a height value 2316 using a height adjustment slider 2318. An aspect ratio lock 2318, if selected, maintains an aspect ratio of the virtual green screen. If the aspect ratio lock 2318 is selected, a change in width will result in a corresponding change in height and vice versa.
A visible switch 2320 makes the virtual green screen visible on the displays if the visible switch 2320 is activated. The immersive content generation system can generate an outline around the virtual green screen if the outline only switch 2321 is selected. The virtual green screen panel 2300 can allow an operator to select the green screen color. In various embodiment, a green screen 2324, a blue screen 2326, a black screen 2328, and a colorless or transparent “green” screen 2330. The virtual green screen panel 2300 can present the selected color value 2332 and a numerical value 2334. A color value slider 2336 allows for adjustment of the color of the virtual green screen.
The operator can adjust the opacity of the virtual green screen using an opacity slider 2338.
The virtual green screen panel 2300 can also provide various tools for adjusting tracking markers. A show marker switch 2322 allows the markers to be toggled on and off on the display. The operator can adjust the shape (e.g., a plus sign (+) or an (x)) of the markers using the shape switch 2342. The operator can adjust the size of the marker using the size selector 2344. The operator can adjust the thickness of the marker using the thickness selector 2346. The operator can adjust a spacing of the tracking markers using the spacing adjustment selector 2348. The operator can adjust an X-offset using the offset-X selector 2350. The operator can adjust a Y-offset using the offset-Y selector 2352.
The operator can select at least one of a green color 2354, a blue color 2356, a white color 2358, and a black color 2360 for the tracker. The operator can adjust a value for the tracker using the value slider 2362. The detached virtual green screen panel 2200 can have preset colors for commonly used tracker colors like black or white or green. But an operator may want a ‘less intense green’—so rather than offering full HSV control, which may be done in some embodiments—the detached virtual green screen panel 2200 can display some preset buttons here and add a “Value” only slider to reduce the V of the HSV system. This allows the operator to dial-back the intensity as needed on the tracking markers for the same reasons as described above for the green screen color itself.
Color wheels are one of the most basic color correction controls. The color wheels represent the color spectrum on a circle and let the operator adjust color in the 2D space of the wheel. The color wheels start out with a movable dot or circle in the center of the wheel. Dragging the dot toward a color area adjusts the color of the image in that direction. The angle at which the operator drags the moveable dot determines the color(s) the operator adjusts, so dragging the dot into the red-orange area makes the overall color more red-orange. The further away from the center of the wheel that the operator drags, the more the operator increases the saturation of the color that the operator is dragging toward.
A color correction can be described as moving a dot or circle away from the opposite color on the wheel. So, if the selected object has an image that is predominately blue, dragging the dot away from the blue area reduces the amount of blue in the image. Color wheels often include a slider to control the brightness, either as a dial around the edge of the wheel or as a straight slider underneath it.
When using the color correction panel 2400, the operator can select a volume, a section, a patch, an object, a window, a sticker, or a portion of the display for correction. For example, the item identifier 2402 lists a volume, a section, a patch, an object, a window, a sticker, or a portion of the display for correction.
In various embodiments, the color correction panel 2400 can present three dials to adjust the color values.
The operator can adjust the offset using the offset dial 2404. The offset dial 2404 can be used to controls shadows/blacks of an image. The offset dial 2404 can achieve this changing the brightness/color levels while leaving mid tones and highlight areas unaffected. The offset selector 2406 can allow the operator to change the value of the offset by sliding the offset selector 2406 within the offset dial 2404. An offset reset button 2408 sets the offset values to be reset to zero. The offset adjustment ring 2410 allows the operator to change the scale for the offset values by rotating the offset adjustment ring 2410. By rotating the offset adjustment ring 2410 the scale inside the offset dial 2404 can change. For example, the scale can be in ones, tens, thousandths, hundredths, or hundred thousandths. The variable scale allows for fine tuning the offset value.
Color sliders let the operator manipulate the red, green, blue, and brightness values directly. The operator can control exactly how much of each color is desired. The operator can change the values of the sliders between using the RGB button 2412, the HSV button 2414, and the Temp button 2416 to allow the operator to change the slider scales. If the RGB button 2412 is selected, as shown in
The offset values 2424 can be shown numerically on the display. An offset brightness slider 2425 can be used to adjust the brightness value for the offset correction.
The operator can adjust the gamma using the gamma dial 2426. The gamma dial 2426 can be used to control the mid tones (middle gray levels) of an image. The color correction panel 2400 can have offset, gamma, and gain wheels affect the shadows OR the mid tones OR the highlights of the image (OR all at once). In various embodiments, it is not the case that offset is only for shadows, gamma is only for midtones, and gain is only for highlights. The “switcher” to choose (2468) controls which range is currently being edited by ALL of the controls—so if the operator choose shadows there on the switcher, then all three of offset, gamma, and gain wheels can be used, and are frequently used, to edit the shadow ‘range’ of colors in the scene. The gamma dial 2426 can achieve this by changing the brightness/color levels of the mid tones while leaving the darks and highlighted areas unaffected. The gamma selector 2428 can allow the operator to change the value of the gamma by sliding the gamma selector 2428 within the gamma dial 2426. A gamma reset button 2430 can reset the gamma value to zero. The gamma adjustment ring 2432 allows the operator to change the scale for the gamma value by rotating the gamma adjustment ring 2432. By rotating the gamma adjustment ring 2432 the scale inside the gamma dial 2426 can change. For example, the scale can be in ones, tens, thousandths, hundredths, or hundred thousandths. The variable scale allows for fine tuning the gamma value.
Color sliders let the operator manipulate the red, green, blue, and brightness values directly. The operator can control exactly how much of each color is desired. The operator can change the values of the sliders between using the RGB button 2412, the HSV button 2414, and the Temp button 2416 to allow the operator to change the slider scales. If the RGB button 2412 is selected, as shown in
The gamma values 2434 can be shown on the display. A gamma brightness slider 2436 can be used to adjust the brightness value for the gamma correction.
The operator can adjust the gain using the gain dial 2438. The gain dial 2438 can be used to control the highlights or white levels of an image. In various embodiments, the gain dial 2438 can achieve this by changing the brightness/color levels of the highlights or white levels while leaving the darks and mid tone areas unaffected. The color correction panel 2400 can have offset, gamma, and gain wheels affect the shadows OR the mid tones OR the highlights of the image (OR all at once). In various embodiments, it is not the case that offset is only for shadows, gamma is only for midtones, and gain is only for highlights. The “switcher” to choose (2468) controls which range is currently being edited by ALL of the controls—so if the operator choose shadows there on the switcher, then all three of offset, gamma, and gain wheels can be used, and are frequently used, to edit the shadow ‘range’ of colors in the scene. The gain selector 2440 can allow the operator to change the value of the gain by sliding the gain selector 2440 within the gain dial 2438. A gain reset button 2442 can reset the gain values to zero. The gain adjustment ring 2444 allows the operator to change the scale for the gain by rotating the gain adjustment ring 2444. By rotating the gain adjustment ring 2444 the scale inside the gain dial 2426 can change. For example, the scale can be in ones, tens, thousandths, hundredths, or hundred thousandths. The variable scale allows for fine tuning the gain value.
Color sliders let the operator manipulate the red, green, blue, and brightness values directly. The operator can control exactly how much of each color is desired. The operator can change the values of the sliders between using the RGB button 2412, the HSV button 2414, and the Temp button 2416 to allow the operator to change the slider scales. If the RGB button 2412 is selected, as shown in
The gain values 2446 can be shown on the display. A gain brightness slider 2448 can be used to adjust the brightness value for the gain correction.
The color correction active switch 2450 enables or disables the color correction for the selected object. The color correction active switch 2450 can be akin to visibility control so the operator can turn on or off the state of the color correction. For example, if the operators has a color correction value for warming up a region on the display (e.g., making it a little bit more orange or yellow) for an exhaust pipe from a motorbike or automobile. The operator can turn it off using the color correction active switch 2450 and see the scene without the results of the color correction enabled.
The color correction bounds switch 2452 allows the display to show the bounds of the region/object/volume in which the color correction is applied on the display. The blend priority value 2454 allows for controlling the rendering priority of one color correction node over another one (e.g., sort order button as described above).
The mix slider 2456 allows the operator to apply a global multiplier to the color correction. A mix value of zero is essentially off value. A mix value of one means the global multiplier is fully applied. The mix slider 2456 provides a scale on the amount of how much the color correction actually contributes to the total color of the selected region/object/volume. In effect, the mix slider 2456 provides a way to turn down the effect of this particular color correction.
The softness slider 2458 allows the operator to adjust the softness of the color correction.
The roundness slider 2460 allows the operator to adjust the roundness of the color correction.
The operator can select the region for the color correction using a Master tab 2462, a Shadows tab 2464, a mid-tones tab 2464 and a Highlights tab 2468 and corresponding region slider 2470. By selecting the Master tab 2462, the color correction is acting upon everything. The shadows, mid tones, and highlights are defined by that region slider 2470. On the region slider 2470, between the first dot and the second dot is considered shadows. Between the second dot and the third is considered mid tones. Between the third dot and the end dot is considered highlights. The operator can change the position of each of these dots. For example, if the scene is very bright the region slider 2470 can adjust the position of the dots to reduce the brightness. The operator may cut highlights and may slide the third dot and move it higher up so that the color correction is only receiving the highest brightness.
The ranges can be edited so that the operator can edit, only extremely bright highlights on a scene with a lot of very bright flares, that may only occur in the 95-100% range of all brightnesses in the scene. To achieve this the operator can select the “Highlights” mode, and then dial the third slider to 0.95 and leave the final slider at 1.0, so as creating a range from 95%-100% for the final “highlights” section to act upon. Then, when editing Offset, Gamma, Gain, and other controls on the panel, with Highlights buttons selected on 2468, those controls will only edit the ‘top 5% bright colors’ in the scene.
The region slider 2470 allows the operator to target a specific section of the scene as opposed to the whole scene as a whole. For example, the operator wants to edit only the brightness or darkness of scene. The operator may want to turn the gain down for the scene or just reduce the highlights in the scenes. Therefore, the region slider 2470 acts like a filter on all of the color correction tools. It can affect all the color wheels as well as that saturation and contrast controls that are below it.
The operator can adjust the exposure slider 2472 to adjust the exposure of the selected region.
The operator can adjust the saturation slider 2474 to adjust the saturation of the selected region.
The operator can adjust the contrast slider 2476 to adjust the contrast of the selected region.
The all projectors button 2478 applies the color correction to all projectors. The all cameras button 2480 applies the correction to all camera. The place button switches the user interface to the placement tab. The reset button 2484 removes all color corrections for the selected object. The max value 2486 sets a maximum value for the range of the exposure slider, should the operators want to push the output values over the standard range.
The handles panel 2500 allows the operator to store the attributes of a virtual object under a file name 2502. The operator can add or remove various attribute types to the handles panel 2500 that can be adjusted. For example, the cube1 attribute 2506 and the transform1 attribute 2508 are available to be added to the attribute editor under the handles panel 2500.
The attributes can also be assigned to various groups (e.g., handlegroup1). For example, motion capture stage origin (mocapStageOrigin) attribute 2510 and the transform1 attribute 2508, and vsRenderControl attribute 2512 can be assigned to the handlegroup 1. Certain attributes can be assigned to specifically to an operator (e.g., my_handle) or a specific electronic device executing the handles panel 2500. For example, the vsRendercontrol attribute 2512 can also be assigned to the my_handle group.

The Color4f attribute 2558 can include an alpha a-value 2568. The a-value 2568 can refer to an opacity. The Color4f attribute 2558 can include a color preview pane 2570.
The enum attribute 2564 can be selected using the handles panel 2500. An enum type can a distinct value type that declares a set of named constants. The operator can select option-1 2566, option-2 2568, option-3 2570, and option-4 2572 for the enum attribute 2564.
The Box2f attribute 2574 can be selected using the handles panel 2500. The Box2f attribute 2574 can include a Box2f x-value 2576, a Box2f y-value 2578, a Box2f width value 2580, and a Box2f height value 2582.
The handles panel 2600 allows the operator to store the attributes of a virtual object under a file name 2302. The operator can add or remove various attribute types to the handles panel 2300 that can be adjusted. For example, the cube1 attribute 2306 and the transform1 attribute 2308 are available to be added to the attribute editor on the handles panel 2300.
The attributes can also be assigned to various groups (e.g., handlegroup1). For example, motion capture stage origin (mocapStageOrigin) attribute 2310 and the transform1 attribute 2308, and vsRenderControl attribute 2312 can be assigned to the handlegroup 1. Certain attributes can be assigned to specifically to an operator (e.g., my_handle) or a specific electronic device executing the handles panel 2300. For example, the vsRendercontrol attribute 2312 can also be assigned to the my_handle group.
The selected attributes can be stored using a select filename 2314. The attributes selected and listed in

VII. Light Capture Device
In some instances, the mechanism may be a handheld pointing device. The pointing device's orientation and position may be tracked using tracking cameras and/or sensors as it moves. The handheld pointing device may include markers to facilitate said tracking. In some instances, the handheld pointing device may have an activation button or trigger. Upon a user activating the activation button or trigger, the content production system may trigger a specific action in the immersive content production system. The light capture device is more of a positional/remote control-type device, rather than a light measure/light capture device. The light capture device can capture light from the Infrared Mocap System Cameras, but the purpose of that is so that the motion capture system can accurately track the 6DOF (position and rotation) of the light capture device in the real world, and so that the operator can then use that data to perform remote-control/pointer-type actions with the device. In doing so, the content production system can determine a point or region of the immersive cave/wall at which the handheld point device is being aimed or directed. The content production system may, based on this determination, select the point or region of the immersive cave/wall. In other embodiments, the selection procedure may include the immersive cave/wall displaying a reticle (e.g., a crosshair) corresponding to a region and/or point at which the aforementioned mechanisms are currently being directed. In doing so, selection of the region and/or point can be facilitated.
The light capturing device 2700 can include a body 2702 that can encase various electronics, sensors, and internal wiring. The body 2702 (e.g., a housing) can include a portion shaped in the form of a grip 2704. The grip 2704 can allow the body 2702 to be held in the hand of a user. The grip 2704 allows for steady control of the light measuring device 2700 and convenient one-handed access of various controls 2704 or a trigger 2706. The controls 2704 can be multi-function buttons mapped to various programmable functions for the immersive content production system. For example, the controls 2704 can be mapped to an on/off switch for a virtual green screen to turn the feature on and off.

The light sensor arms 2710 can extend at various angle and elevations from the body 2702 to enable the light sensors 2708 to capture light at various points around the light capturing device 2700. In various embodiments, the light sensor arms 2710 can include various lengths. In various embodiments, the light sensor arms 2710 can be flexible to enable the light sensor 2708 to be precisely positioned. The configuration of the plurality of light sensors 2708 on the light capturing device 2700 can be known as a crown.
In various embodiments, multiple light capture devices 2700 can be used on the same immersive content production set. In order for the motion tracking system to distinguish between the each of the multiple light capture devices 2700, a distinguishable or unique crown can be used for each of the multiple light capture devices 2700. In various embodiments, the predetermined configuration can include a first light marker mounted to a first sensor arm that is mounted perpendicular to the handgrip on an opposite side of the housing. The predetermined configuration can include a plurality of additional markers arms with additional markers mounted thereon. The additional sensor arms can be mounted to the opposite side of the housing of the handgrip. The additional markers can be mounted at distinct angles above and below the first sensor arm. The additional markers can be distributed in a distinct pattern.
The light capture device 2700 can include various universal mounts 2714. The universal mounts 2714 can enable various modules to be coupled with the light capturing device 2700. In additional, the universal mounts 2714 allow for different placement for mounting the plurality of light sensors 2708.
The light capture device 2700 can include an electronic device mount 2716 for removably coupling an electronic device 2718 (e.g., a smartphone). The electronic device 2718 can execute one or more applications for positioning the light measurement device 2700.
The light capture device 2700 can include one or more antenna 2720. The antenna 2720 can wirelessly communicate data back to a control system (e.g., StageCraft) using any wireless protocol (e.g., Bluetooth, Wi-Fi, etc.).

In various embodiments, the controller 2722 can be an Arduino microcontroller based platform. The controller 2722 can receive inputs from the controls 2704 or the trigger 2706.
The light capture device 2700 has multiple use cases. In one use case, the light capture device 2700 can be used to draw the frustum of the taking camera. The light capture device 2700 can simulate a position of a camera and the MOCAP system can draw a position of the frustum for that camera. This can be called “painting the frustum.”
Other use cases of the light capture device 2700 can include use for virtual green screens. Actors can be performing on screen and the device can ensure that there is a green screen around certain features of actors or costumes. The light capture device 2700 can be used to draw the green screen behind the actors to help replace part of the background.

VIII. Computing Device
Each of the embodiments disclosed herein can be implemented in a special-purpose computer system.
Bus subsystem 3102 provides a mechanism for letting the various components and subsystems of computer system 3100 communicate with each other as intended. Although bus subsystem 3102 is shown schematically as a single bus, alternative embodiments of the bus subsystem can utilize multiple buses. Bus subsystem 3102 can be any of several types of bus structures including a memory bus or memory controller, a peripheral bus, and a local bus using any of a variety of bus architectures. For example, such architectures can include an Industry Standard Architecture (ISA) bus, Micro Channel Architecture (MCA) bus, Enhanced ISA (EISA) bus, Video Electronics Standards Association (VESA) local bus, and Peripheral Component Interconnect (PCI) bus, which can be implemented as a Mezzanine bus manufactured to the IEEE P1386.1 standard.
Processing unit 3104, which can be implemented as one or more integrated circuits (e.g., a conventional microprocessor or microcontroller), controls the operation of computer system 3100. One or more processors can be included in processing unit 3104. These processors can include single core or multicore processors. In certain embodiments, processing unit 3104 can be implemented as one or more independent processing units 3132 and/or sub processing unit 3134 with single or multicore processors included in each processing unit. In other embodiments, processing unit 3104 can also be implemented as a quad-core processing unit formed by integrating two dual-core processors into a single chip.
In various embodiments, processing unit 3104 can execute a variety of programs in response to program code and can maintain multiple concurrently executing programs or processes. At any given time, some or all of the program code to be executed can be resident in processor(s) 3104 and/or in storage subsystem 3118. Through suitable programming, processor(s) 3104 can provide various functionalities described above. Computer system 3100 can additionally include a processing acceleration unit 3106, which can include a digital signal processor (DSP), a special-purpose processor, and/or the like. And, in some embodiments, the processing unit or another component of system 3100 can include and/or operate a real-time gaming engine or other similar real-time rendering engine. Such an engine can render two-dimensional (2D) images from 3D data at interactive frame rates (e.g., 24, 48, 72, 96, or more frames per second). In one aspect, the real-time gaming engine can load the virtual environment for display on the displays surrounding the performance area. In some embodiments, the real-time gaming engine can load virtual assets into the virtual environment. The real-time gaming engine can then permit the virtual assets to interact or move according to simulated physics information stored by the real-time gaming engine. The real-time gaming engine can also update the virtual environment based on the movement and orientation of the taking camera(s).
I/O subsystem 3108 can include user interface input devices and user interface output devices. User interface input devices can include a keyboard, pointing devices such as a mouse or trackball, a touchpad or touch screen incorporated into a display, a scroll wheel, a click wheel, a dial, a button, a switch, a keypad, audio input devices with voice command recognition systems, microphones, and other types of input devices. User interface input devices can include, for example, motion sensing and/or gesture recognition devices such as the Microsoft Kinect® motion sensor that enables users to control and interact with an input device, such as the Microsoft Xbox® 360 game controller, through a natural user interface using gestures and spoken commands. User interface input devices can also include eye gesture recognition devices such as the Google Glass® blink detector that detects eye activity (e.g., ‘blinking’ while taking pictures and/or making a menu selection) from users and transforms the eye gestures as input into an input device (e.g., Google Glass®). Additionally, user interface input devices can include voice recognition sensing devices that enable users to interact with voice recognition systems (e.g., Siri® navigator), through voice commands. In some embodiments, the user interface devices enable an operator to provide input indicating the types of virtual assets and/or effects to be integrated into the virtual environment displayed during the performance. The operator can also indicate the particular configurations or trigger movements of the performer and/or physical objects in the performance area that are to be used to begin the loading and presentation of certain virtual assets. In some embodiments, the input received from the operator can occur in real-time and/or concurrently with a performance
The system 3100 can include one or more displays 3132. The displays 3132 can be the displays 104 depicted in
The system 3100 can include one or more cameras 3134. The one or more cameras can be digital cameras. Digital cinematography captures motion pictures digitally in a process analogous to digital photography. Professional cameras can include the Sony CineAlta(F) Series, Blackmagic Cinema Camera, RED ONE, Arriflex D-20, D-21 and Alexa, Panavisions Genesis, Silicon Imaging SI-2K, Thomson Viper, Vision Research Phantom, IMAX 3D camera based on two Vision Research Phantom cores, Weisscam HS-1 and HS-2, GS Vitec noX, and the Fusion Camera System. Digital cinematography cameras can capture images using complementary metal-oxide semiconductor (CMOS) or charge coupled device (CCD) sensors, usually in one of two arrangements. Single chip cameras that are designed specifically for the digital cinematography market often use a single sensor (much like digital photo cameras), with dimensions similar in size to a 16 or 35 mm film frame or even (as with the Vision 65) a 65 mm film frame. An image can be projected onto a single large sensor exactly the same way it can be projected onto a film frame, so cameras with this design can be made with positive lock (PL), Panavision (PV) and similar mounts, in order to use the wide range of existing high-end cinematography lenses available. Their large sensors also let these cameras achieve the same shallow depth of field as 35 or 65 mm motion picture film cameras, which many cinematographers consider an essential visual tool.
Unlike other video formats, which are specified in terms of vertical resolution (for example, 1080p, which is 1920×1080 pixels), digital cinema formats are usually specified in terms of horizontal resolution. As a shorthand, these resolutions are often given in “nK” notation, where n is the multiplier of 3124 such that the horizontal resolution of a corresponding full-aperture, digitized film frame is exactly 1024n pixels.
For instance, a 2K image is 2048 pixels wide, and a 4K image is 4096 pixels wide. Vertical resolutions vary with aspect ratios though; so a 2K image with an HDTV (16:9) aspect ratio is 2048×1152 pixels, while a 2K image with a standard definition television (SDTV) or Academy ratio (4:3) is 2048×1536 pixels, and one with a Panavision ratio (2.39:1) would be 2048×856 pixels, and so on. Due to the “nK” notation not corresponding to specific horizontal resolutions per format a 2K image lacking, for example, the typical 35 mm film soundtrack space, is only 1828 pixels wide, with vertical resolutions rescaling accordingly.
All formats designed for digital cinematography are progressive scan, and capture usually occurs at the same 24 frame per second rate established as the standard for 35 mm film. Some films have a High Frame Rate of 48 fps, although most traditional theaters use 24 fps. The DCI standard for cinema usually relies on a 1.89:1 aspect ratio, thus defining the maximum container size for 4K as 4096×2160 pixels and for 2K as 2048×1080 pixels.
Broadly, several workflow paradigms can be used for data acquisition and storage in digital cinematography. With video-tape-based workflow, video is recorded to tape on set. This video is then ingested into a computer running non-linear editing software, using a deck. Upon ingestion, a digital video stream from tape is converted to computer files. These files can be edited directly or converted to an intermediate format for editing. Then video is output in its final format, possibly to a film recorder for theatrical exhibition, or back to video tape for broadcast use. Original video tapes are kept as an archival medium. The files generated by the non-linear editing application contain the information necessary to retrieve footage from the proper tapes, should the footage stored on the computer's hard disk be lost. With increasing convenience of file-based workflows, the tape-based workflows have become marginal in recent years.
Digital cinematography can use tapeless or file-based workflows. This trend has accelerated with increased capacity and reduced cost of non-linear storage solutions such as hard disk drives, optical discs, and solid-state memory. With tapeless workflows digital video is recorded as digital files onto random-access media like optical discs, hard disk drives or flash memory-based digital magazines. These files can be easily copied to another storage device, typically to a large RAID (array of computer disks) connected to an editing system. Once data is copied from the on-set media to the storage array, they are erased and returned to the set for more shooting.
Such RAID arrays, both of managed (for example, storage area networks (SANs) and networked attached storage (NASs) and unmanaged (for example, just a bunch of disks (JBoDs) on a single computer workstation), are necessary due to the throughput required for real-time (320 Megabits per second for 2K @ 24 frames per second) or near-real-time playback in post-production, compared to throughput available from a single, yet fast, hard disk drive. Such requirements are often termed as on-line or cloud storage. Post-production not requiring real-time playback performances (typically for lettering, subtitling, versioning and other similar visual effects) can be migrated to slightly slower RAID stores.
Short-term archiving, if ever, is accomplished by moving the digital files into slower redundant array of independent disks (RAID) arrays (still of either managed or unmanaged type, but with lower performances), where playback capability is poor to non-existent (unless via proxy images), but minimal editing and metadata harvesting still feasible. Such intermediate requirements easily fall into the mid-line storage category.
Long-term archiving is accomplished by backing up the digital files from the RAID, using standard practices and equipment for data backup from the information technology industry, often to data tapes (like linear tape open (LTOs)).
The system can include one or more spherical cameras. A spherical camera can be called an omnidirectional camera, also known as 360-degree camera, is a camera having a field of view that covers approximately the entire sphere or at least a full circle in the horizontal plane. 360-degree videos, also known as immersive videos, or spherical videos, are video recordings where a view in every direction is recorded at the same time, shot using an omnidirectional camera or a collection of cameras. During playback on normal flat display the viewer has control of the viewing direction like a panorama. It can also be played on a displays or projectors arranged in a sphere or some part of a sphere.
360-degree video is typically recorded using either a special rig of multiple cameras, or using a dedicated camera that contains multiple camera lenses embedded into the device, and filming overlapping angles simultaneously. Through a method known as video stitching, this separate footage is merged into one spherical video piece, and the color and contrast of each shot is calibrated to be consistent with the others. This process is done either by the camera itself, or using specialized software that can analyze common visuals and audio to synchronize and link the different camera feeds together. Generally, the only area that cannot be viewed is the view toward the camera support.
360-degree video is typically formatted in an equi-rectangular projection and is either monoscopic, with one image directed to both eyes, or stereoscopic, viewed as two distinct images directed individually to each eye for a 3D effect. Due to this projection and stitching, equi-rectangular video exhibits a lower quality in the middle of the image than at the top and bottom.
Specialized omnidirectional cameras and rigs have been developed for the purpose of filming 360-degree video, including rigs such as GoPro's Omni and Odyssey (which consist of multiple action cameras installed within a frame), and contained cameras like the HumanEyes Vuze and Nokia OZO, There have also been handheld dual-lens cameras such as the Ricoh Theta S, Samsung Gear 360, Garmin VIRB 360, and the Kogeto Dot 360—a panoramic camera lens accessory developed for the iPhone 4, 4S, and Samsung Galaxy Nexus.
User interface input devices can also include, without limitation, three dimensional (3-D) mice, joysticks or pointing sticks, gamepads and graphic tablets, and audio/visual devices such as speakers, digital cameras, digital camcorders, portable media players, webcams, image scanners, fingerprint scanners, barcode reader 3-D scanners, 3-D printers, laser rangefinders, and eye gaze monitoring devices. Additionally, user interface input devices can include, for example, medical imaging input devices such as computed tomography, magnetic resonance imaging, position emission tomography, medical ultrasonography devices. User interface input devices can also include, for example, audio input devices such as MIDI keyboards, digital musical instruments and the like.
User interface output devices can include a display subsystem, indicator lights, or non-visual displays such as audio output devices, etc. The display subsystem can be a cathode ray tube (CRT), a flat-panel device, such as that using a liquid crystal display (LCD) or plasma display, a projection device, a touch screen, and the like. In general, use of the term “output device” is intended to include all possible types of devices and mechanisms for outputting information from computer system 3100 to a user or other computer. For example, user interface output devices can include, without limitation, a variety of display devices that visually convey text, graphics and audio/video information such as monitors, printers, speakers, headphones, automotive navigation systems, plotters, voice output devices, and modems.
Computer system 3100 can comprise a storage subsystem 3118 that comprises software elements, shown as being currently located within a system memory 3110. System memory 3110 can store program instructions that are loadable and executable on processing unit 3104, as well as data generated during the execution of these programs.
Depending on the configuration and type of computer system 3100, system memory 3110 can be volatile (such as random access memory (RAM)) and/or non-volatile (such as read-only memory (ROM), flash memory, etc.) The RAM typically contains data and/or program modules that are immediately accessible to and/or presently being operated and executed by processing unit 3104. In some implementations, system memory 3110 can include multiple different types of memory, such as static random access memory (SRAM) or dynamic random access memory (DRAM). In some implementations, a basic input/output system (BIOS), containing the basic routines that help to transfer information between elements within computer system 3100, such as during start-up, can typically be stored in the ROM. By way of example, and not limitation, system memory 3110 also illustrates application programs 3112, which can include client applications, web browsers, mid-tier applications, relational database management systems (RDBMS), etc., program data 3114, and an operating system 3116. By way of example, operating system 3116 can include various versions of Microsoft Windows®, Apple Macintosh®, and/or Linux operating systems, a variety of commercially-available UNIX® or UNIX-like operating systems (including without limitation the variety of GNU/Linux operating systems, the Google Chrome® OS, and the like) and/or mobile operating systems such as iOS, Windows® Phone, Android® OS, BlackBerry® 10 OS, and Palm® OS operating systems.
Storage subsystem 3118 can also provide a tangible computer-readable storage medium for storing the basic programming and data constructs that provide the functionality of some embodiments. Software (programs, code modules, instructions) that when executed by a processor provide the functionality described above can be stored in storage subsystem 3118. These software modules or instructions can be executed by processing unit 3104. Storage subsystem 3118 can also provide a repository for storing data used in accordance with the present invention.
Storage subsystem 3100 can also include a computer-readable storage media reader 3120 that can further be connected to computer-readable storage media 3122. Together and, optionally, in combination with system memory 3110, computer-readable storage media 3122 can comprehensively represent remote, local, fixed, and/or removable storage devices plus storage media for temporarily and/or more permanently containing, storing, transmitting, and retrieving computer-readable information.
Computer-readable storage media 3122 containing code, or portions of code, can also include any appropriate media known or used in the art, including storage media and communication media, such as but not limited to, volatile and non-volatile, removable and non-removable media implemented in any method or technology for storage and/or transmission of information. This can include tangible computer-readable storage media such as RAM, ROM, electronically erasable programmable ROM (EEPROM), flash memory or other memory technology, CD-ROM, digital versatile disk (DVD), or other optical storage, magnetic cassettes, magnetic tape, magnetic disk storage or other magnetic storage devices, or other tangible computer readable media. This can also include nontangible computer-readable media, such as data signals, data transmissions, or any other medium which can be used to transmit the desired information and which can be accessed by computing system 3100.
By way of example, computer-readable storage media 3122 can include a hard disk drive that reads from or writes to non-removable, nonvolatile magnetic media, a magnetic disk drive that reads from or writes to a removable, nonvolatile magnetic disk, and an optical disk drive that reads from or writes to a removable, nonvolatile optical disk such as a CD ROM, DVD, and Blu-Ray® disk, or other optical media. Computer-readable storage media 3122 can include, but is not limited to, Zip® drives, flash memory cards, universal serial bus (USB) flash drives, secure digital (SD) cards, DVD disks, digital video tape, and the like. Computer-readable storage media 3122 can also include, solid-state drives (SSD) based on non-volatile memory such as flash-memory based SSDs, enterprise flash drives, solid state ROM, and the like, SSDs based on volatile memory such as solid state RAM, dynamic RAM, static RAM, DRAM-based SSDs, magnetoresistive RAM (MRAM) SSDs, and hybrid SSDs that use a combination of DRAM and flash memory based SSDs. The disk drives and their associated computer-readable media can provide non-volatile storage of computer-readable instructions, data structures, program modules, and other data for computer system 3100.
Communications subsystem 3124 provides an interface to other computer systems and networks. Communications subsystem 3124 serves as an interface for receiving data from and transmitting data to other systems from computer system 3100. For example, communications subsystem 3124 can enable computer system 3100 to connect to one or more devices via the Internet. In some embodiments communications subsystem 3124 can include radio frequency (RF) transceiver components for accessing wireless voice and/or data networks (e.g., using cellular telephone technology, advanced data network technology, such as 3G, 4G or EDGE (enhanced data rates for global evolution), Wi-Fi (IEEE 802.11 family standards, or other mobile communication technologies, or any combination thereof), global positioning system (GPS) receiver components, and/or other components. In some embodiments communications subsystem 3124 can provide wired network connectivity (e.g., Ethernet) in addition to or instead of a wireless interface.
In some embodiments, communications subsystem 3124 can also receive input communication in the form of structured and/or unstructured data feeds 3126, event streams 3128, event updates 3130, and the like on behalf of one or more users who can use computer system 3100.
By way of example, communications subsystem 3124 can be configured to receive data feeds 3126 in real-time from users of social networks and/or other communication services such as Twitter® feeds, Facebook® updates, web feeds such as Rich Site Summary (RSS) feeds, and/or real-time updates from one or more third party information sources.
Additionally, communications subsystem 3124 can also be configured to receive data in the form of continuous data streams, which can include event streams 3128 of real-time events and/or event updates 3130, that can be continuous or unbounded in nature with no explicit end. Examples of applications that generate continuous data can include, for example, sensor data applications, financial tickers, network performance measuring tools (e.g. network monitoring and traffic management applications), clickstream analysis tools, automobile traffic monitoring, and the like.
Communications subsystem 3124 can also be configured to output the structured and/or unstructured data feeds 3126, event streams 3128, event updates 3130, and the like to one or more databases that can be in communication with one or more streaming data source computers coupled to computer system 3100.
