UNIFORM FACIAL APPEARANCE IN A CAPTURED VIDEO STREAM

Abstract

An information handling system includes a camera and a display controller. The camera captures multiple images to form a video stream. The display controller outputs a background image pattern on a display screen. The color temperature and the brightness of the background image pattern are set to defined levels. The display controller receives the video stream from the camera. The display controller outputs the video stream as a separate stream from the background image pattern on the display screen. The luminance of the video stream is controlled independent from the color temperature and brightness of the background image pattern.

Description

FIELD OF THE DISCLOSURE

The present disclosure generally relates to information handling systems, and more particularly relates to providing a uniform facial appearance in a captured video stream.

BACKGROUND

As the value and use of information continues to increase, individuals and businesses seek additional ways to process and store information. One option is an information handling system. An information handling system generally processes, compiles, stores, or communicates information or data for business, personal, or other purposes. Technology and information handling needs and requirements can vary between different applications. Thus, information handling systems can also vary regarding what information is handled, how the information is handled, how much information is processed, stored, or communicated, and how quickly and efficiently the information can be processed, stored, or communicated. The variations in information handling systems allow information handling systems to be general or configured for a specific user or specific use such as financial transaction processing, airline reservations, enterprise data storage, or global communications. In addition, information handling systems can include a variety of hardware and software resources that can be configured to process, store, and communicate information and can include one or more computer systems, graphics interface systems, data storage systems, networking systems, and mobile communication systems. Information handling systems can also implement various virtualized architectures. Data and voice communications among information handling systems may be via networks that are wired, wireless, or some combination.

SUMMARY

An information handling system includes a camera and a display controller. The camera captures multiple images to form a video stream. The display controller may output a background image pattern on a display screen. The color temperature and the brightness of the background image pattern may be set to defined levels. The display controller may receive the video stream from the camera. The display controller may output the video stream as a separate stream from the background image pattern on the display screen. The luminance of the video stream may be controlled independent from the color temperature and brightness of the background image pattern.

DETAILED DESCRIPTION OF THE DRAWINGS

The following description in combination with the Figures is provided to assist in understanding the teachings disclosed herein. The description is focused on specific implementations and embodiments of the teachings and is provided to assist in describing the teachings. This focus should not be interpreted as a limitation on the scope or applicability of the teachings.

FIGS. 1 and 2 illustrate a portion of a system 100 including an information handling system 102 and a display device 104 according to at least one embodiment of the present disclosure. For purposes of this disclosure, an information handling system can include any instrumentality or aggregate of instrumentalities operable to compute, calculate, determine, classify, process, transmit, receive, retrieve, originate, switch, store, display, communicate, manifest, detect, record, reproduce, handle, or utilize any form of information, intelligence, or data for business, scientific, control, or other purposes. For example, an information handling system may be a personal computer (such as a desktop or laptop), tablet computer, mobile device (such as a personal digital assistant (PDA) or smart phone), server (such as a blade server or rack server), a network storage device, or any other suitable device and may vary in size, shape, performance, functionality, and price. The information handling system may include random access memory (RAM), one or more processing resources such as a central processing unit (CPU) or hardware or software control logic, ROM, and/or other types of nonvolatile memory. Additional components of the information handling system may include one or more disk drives, one or more network ports for communicating with external devices as well as various input and output (I/O) devices, such as a keyboard, a mouse, touchscreen and/or a video display. The information handling system may also include one or more buses operable to transmit communications between the various hardware components.

Information handling system 102 includes a processor 110, a camera 112, a display controller 114, a memory 116, and a local dimming control 118. Display device 104 includes screen 120, which in turn may be utilized to output a background image pattern 122 and a video stream 124. In an example, local dimming control 118 may be located within display device 104 without varying from the scope of this disclosure. Information handling system 102 may communicate with display device 104 via display controller 114. Information handling system 102 may include additional components without varying from the scope of this disclosure.

In certain situations, an individual associated with information handling system 102 may record his or herself with camera 112 to create a video stream. In an example, the video stream may be utilized for any suitable function, such as for a video conference or the like. The experience of the individual during the creation of the video stream may be affected by multiple different factors including, but not limited to, the individual's facial appearance and the quality of the video stream. The facial appearance of the individual may be affected by different conditions, such as shadows, lighting conditions, or the like. The recording and streaming of a video stream may be improved in information handling system 102 by providing background image pattern 122 on display device 104, which in turn may adjust or add lighting to obtain optimal facial appearance of the individual within video stream 124.

In an example, information handling system 102, via display controller 114, may combine the video stream with a background lighting to provide a dual channel output to display device 104. In this example, background image pattern 122 may be a main channel or stream of the dual channel output and video stream 124 may be a secondary channel or stream of the dual channel output. The secondary channel may be a picture-in-picture (PIP) channel of the output on screen 120. In an example, the luminance of background image pattern 122 and video stream 124 may be independently controlled as will be described with respect to FIGS. 2-6 below.

FIG. 2 illustrates a display controller 200 according to at least one embodiment of the present disclosure. Display controller 200 may be substantially similar to display controller 114. Display controller 200 includes a video timing generator 202, a test pattern generator 204, a video receiver/switch 206, channel video processing paths 208 and 210, video overlay circuitry 212, and a multiplexor 214. Channel video processing path 208 includes a channel processing component 220, a red/green/blue (RGB) gain/offset component 222, a gamma correction component 224, and a uniformity correction component 226. Channel video processing path 210 includes a channel processing component 230, a RGB gain/offset component 232, a gamma correction component 234, and a uniformity correction component 236. Display controller 200 further includes a bypassed video path 238.

During operation of display controller 200 video receiver/switch 206 may receive one or more video inputs, such as a video stream from camera 112 of FIG. 1, and provide the video inputs to channel video processing path 208 or 210. In an example, a video stream 240 may be received by video receiver/switch 206 and the video stream may be provided to channel video processing path 208. Components 220, 222, 224, and 226 of channel video processing path 208 may perform one or more operations to adjust video stream 240 into video stream 242. For example, channel processing component 220 may adjust the size of video stream 240 based on a user defined video size setting, such as a video size setting 302 in FIG. 3. In certain examples, channel processing component 220 may utilize the user defined video size setting to scale the video stream 240 to a particular percentage of its original size and set a location of the video stream on the screen of the display device. In an example, video stream 242 may be substantially similar to video stream 124 of FIG. 1 and background image pattern 250 may be substantially similar to background image pattern 122 of FIG. 1.

Video timing generator 202 and test pattern generator 204 may combine to create a background image pattern 250. In certain examples, video timing generator 202 may be any suitable timing-based video resolution generator, such as a 4k resolution, a high definition (HD) resolution, or the like. In an example, test pattern generator 204 may generate a programmable RGB pattern based on user defined parameters, such as a user ring color temperature setting 308 in FIG. 3. Based on the user ring color temperature setting, test pattern generator 204 set a color temperature for background image pattern 250. Test pattern generator 204 may provide background image pattern 250 to multiplexor 214, which in turn may provide the background image pattern along bypassed video path 238 to video overlay output 212 while in the bypassed mode. In an example, background image pattern 250 may bypass components 230, 232, 234, 236 of channel video processing path 210 to prevent luminance reduction within the background image pattern that may be caused by processing of the image by any of the components.

While bypassed video path 238 is illustrated in FIG. 2 as bypassing all components 230, 232, 234, 236 of channel video processing path 210, background image pattern 250 may not always bypass all of the components. For example, in the bypassed mode, gamma correction component 234 may perform one or more operations on background image pattern 250 to maximize light output in the background image pattern.

In an example, video overlay output 212 may combine, in any suitable manner, background image pattern 250 and video stream 242 into a single output with two different channels or streams. For example, video overlay output 212 may overlay video stream 242 as a PIP video within background image pattern 250. In this example, the combined output of background image pattern 250 and PIP video stream 242 may be provided to screen 120 of display device 104 in FIG. 1.

FIG. 3 illustrates a graphical user interface (GUI) 300 for setting display characteristics of images on a display device according to at least one embodiment of the present disclosure. In an example, GUI 300 may be any suitable control interface including, but not limited to, a monitor on screen display (OSD) interface. GUI 300 may include a video size setting 302, a ring brightness setting 304, a video brightness setting 306, and a ring color temperature setting 308. In an example, GUI 300 may be an interface of information handling system 102 and displayed on screen 120 of display device 104 in FIG. 1 and may be utilized to customize a facial illumination mode in the information handling system. GUI 300 may include additional settings without varying from the scope of this disclosure.

In an example, GUI 300 may be utilized by an individual associated with information handling system 102 of FIG. 1 to separately adjust properties of background image pattern or ring 122 and video stream 124. The individual may select from different size options of video size setting 302. For example, the individual may select either small or medium within video size setting 302 and this selected size may be utilized by display controller 200 of FIG. 2 while processing the video stream. While two size options are illustrated in FIG. 3, any suitable number of size options, user enterable sizes, or the like may be provided in GUI 300 without varying from the scope of this disclosure. Alternatively, based on information from camera 112, the video size setting may also be automatically selected by display controller 114. The information from camera 112 may include, but is not limited to, an automatic exposure level and average luminance detected in a face area of the image.

In certain examples, ring brightness setting 304 may be any selectable item to adjust and set a brightness level for the ring or background image pattern 250 of FIG. 2. Similarly, video brightness setting 306 may be any selectable item to adjust and set a brightness level for the video stream 242 of FIG. 2. A user may utilize ring color temperature setting 308 to manually adjust the balance of red, green, and blue in background image pattern or ring 250 of FIG. 2. In certain examples, values of ring brightness setting 304, video brightness setting 306, and ring color temperature setting 308 may be provided to display controller 200 of FIG. 2, which in turn may utilize the settings to adjust the properties of video stream 242 and background image pattern or ring 250.

FIG. 4 illustrates a backlight matrix control 400 for a display device 402 according to at least one embodiment of the present disclosure. Backlight matrix control 400 includes a local dimming control circuit 404, which may be a component of display controller 200 of FIG. 2, within processor 110 of FIG. 1, located within display device 104 of FIG. 1, or the like. Local dimming control circuit 404 includes inputs 410, 412, and 414, and an output 416. Display device 402 may provide a PIP video stream 420 and a background image pattern or ring 422. Display device 402 may be substantially similar to display device 104 of FIG. 1. PIP video stream 420 may be substantially similar to video stream 124 of FIG. 1 and 242 of FIG. 2. In an example, background image pattern or ring 422 may be substantially similar to background image pattern 122 of FIG. 1 and background image pattern or ring 250 of FIG. 2.

In an example, input 410 may receive a video stream, such as PIP video stream 420, input 412 may receive size and positional data associated with the video stream, and input 414 may receive ring brightness data and video brightness data. In certain examples, the video stream at input 410 may be received from any suitable source including, but not limited to, camera 112 of FIG. 1 and video receiver/switch 206 of FIG. 2. The size and positional data at input 412 may be received from the user selection of video size setting 302 in GUI 300 of FIG. 3. Additionally, the ring brightness data and video brightness data at input 414 may be received from user selection of ring brightness setting 304 and video brightness setting 306 in GUI 300 of FIG. 3. Local dimming control circuit 404 may utilize the data received at inputs 410, 412, and 414 to provide one or more backlight matrix control signals 416 to a backlight matrix 430 of display device 402.

In an example, backlight matrix control signals 416 may be utilized to selectively dim the luminance of a backlight matrix in areas that that video stream 420 is located and increase the areas of the backlight matrix associated with background image pattern or ring 422. For example, luminance brightness of backlight matrix associated with background image pattern 422 may be increased to a maximum luminance and the brightness of the PIP video stream 420 may be reduced.

FIG. 5 illustrates a display device 500 having a backlight matrix granularity 502, a background image pattern ring 504, and PIP video stream 506 according to at least one embodiment of the present disclosure. Display device 500 may be substantially similar to display device 104 of FIG. 1. Backlight matrix granularity 502 includes multiple cells 510. In an example, the size of cells 510 may be set by the backlight cell grid of display device 500. In certain examples, cells 510 may be sufficiently small such that background image pattern ring 504 and PIP video stream 506 do not overlap within one or more cells. For example, no cell 510 includes portions of both background image pattern ring 504 and PIP video stream 506. In an example, edges of video stream 506 may snap or align with edges of cells 510.

In an example, PIP video stream 506 may be centered within backlight matrix 502 and a subset of cells 510 may be associated with the PIP video stream and another subset 520 of the cells may be associated with background image pattern ring 504. Each cell 510 may be independently controlled with respect to brightness, color, and hue, such that the brightness of PIP video stream 506 may be independently controlled by local dimming control circuit 404 of FIG. 4. In an example, cells 510 behind video stream 506 may be directly dimmed without affecting the luminance brightness of background image pattern ring 504. Additionally, a processor does not need to perform compensation on PIP video stream 506 because background image pattern ring 504 and the PIP video stream do not overlap. In an example, the gamma curve of background image pattern ring 504 and PIP video stream 506 may be different based on the driving strength of backlight cells 520 behind the background image pattern ring being different from the driving strength of backlight cells behind the PIP video stream.

FIG. 6 illustrates a display device 600 having a backlight matrix granularity 602, a background image pattern ring 604, and PIP video stream 606 according to at least one embodiment of the present disclosure. Display device 600 may be substantially similar to display device 104 of FIG. 1. Backlight matrix granularity 602 includes multiple cells 610. In an example, the size of cells 610 may be set by the backlight cell grid of display device 600. In certain examples, the granularity of cells 610 within backlight matrix 602 may not be sufficiently small to prevent background image pattern ring 604 and PIP video stream 606 from overlapping within one or more cells. For example, each of cells 620 include portions of both background image pattern ring 604 and PIP video stream 606, each of cells 622 are located behind only background image pattern ring 604, and each of cells 624 are located behind only PIP video stream 606.

In an example, the different subsets of cells 610, such as cells 622 and 624, that do not include overlap from both background image pattern ring 604 and PIP video stream 606 may be independently controlled with respect to brightness, color, and hue, such that the brightness of background image pattern ring 604 may be independently controlled by local dimming control circuit 404 of FIG. 4. In an example, cells 624 behind video stream 606 may be directly dimmed without affecting the luminance brightness of background image pattern ring 604. In certain examples, local dimming control circuit 404 of FIG. 4 may set a uniformity compensation gain for cell 624 to 100%.

In certain examples, display controller 200 of FIG. 2, local dimming control circuit 404 of FIG. 4, or any other suitable processor, perform a uniformity compensation on overlapping cells 620. In particular, each cell 620 may be divided into smaller uniformity compensation unit cells 630 and one or more operations may be performed on these cells. For example, display controller 200 of FIG. 2 may drive the luminance brightness of cells 630 that are located behind background image pattern ring 604 to a desired brightness and then scale cells 632 behind PIP video stream 606. In certain examples, local dimming control circuit 404 of FIG. 4 may calculate a uniformity compensation gain for the cells 632. In an example, the uniformity compensation gain may be calculated based on equation 1 below:

Uniformity compensation gain=(L_VideoMax/L_RingMax)×100%  EQ. 1

Based on equation 1 above, the luminance and uniformity compensation of cells 630 and 632 may provide a transition between cells 624 and cells 610 of the display device. In an example, the higher luminance of background image pattern ring 604 may enable a uniform appearance within video stream 606.

FIG. 7 is a flow diagram of a method 700 for providing a uniform facial appearance during a video recording according to at least one embodiment of the present disclosure, starting at block 702. In an example, method 700 may be performed by any suitable component including, but not limited to, camera 112 and display controller 114 of FIG. 1, and local dimming control circuit 404 of FIG. 4. It will be readily appreciated that not every method step set forth in this flow diagram is always necessary, and that certain steps of the methods may be combined, performed simultaneously, in a different order, or perhaps omitted, without varying from the scope of the disclosure.

At block 704, a video stream is captured. In an example, the video stream may be captured by a camera of the information handling system. At block 706, a video stream size indication is received. In an example, the video stream size indication may be received from a user input in a GUI. At block 708, a size of the video stream is adjusted based on the video stream size indication. In certain examples, a display controller of the information handling system may perform the size adjustment of the video stream.

At block 710, a background image pattern ring brightness level request is received. In an example, the background image pattern ring brightness level request may be received via the GUI. At block 712, the brightness level for the background image pattern ring is adjusted based on the request. At block 714, the video stream is provided as an overlay for the background image pattern ring. At block 716, a determination is made whether a cell of a background matrix includes portions of both the background image pattern ring and the video stream.

If the cell does not include portions of both the background image pattern ring and the video stream, the brightness of the background image pattern ring or the video stream is directly and separately controlled at block 718. If the cell does include portions of both the background image pattern ring and the video stream, a uniformity compensation is adjusted within the cell at block 720. At block 722 the background image pattern ring and the video stream are provided to a display device and the flow ends at block 724.
