Abstract
A system for producing virtual camera motion in a motion picture medium in which an array of cameras is deployed along a preselected path with each camera focused on a common scene. Each camera is triggered simultaneously to record a still image of the common scene, and the images are transferred from the cameras in a preselected order along the path onto a sequence of frames in the motion picture medium such as motion picture film or video tape. Because each frame shows the common scene from a different viewpoint, placing the frames in sequence gives the illusion that one camera has moved around a frozen scene (i.e., virtual camera motion). In another embodiment, a two-dimensional array of video cameras is employed. Each camera synchronously captures a series of images in rapid succession over time. The resulting array of images can be combined in any order to create motion pictures having a combination of virtual camera motion and time-sequence images.
Description




FIELD OF THE INVENTION




The present invention relates generally to the field of cinematography. More specifically, the present invention discloses a system for producing motion picture scenes that embody time-independent virtual camera movement. An array of specialized modular cameras simultaneously records photographic images of a scene and the resulting photographic images are placed in a motion picture medium and viewed in succession, conveying the illusion that a single camera has moved around a scene frozen in time.




STATEMENT OF THE PROBLEM




Presently, film directors wishing to convey a sense of time passing for the viewer of a scene while time appears stopped for the subject of the same scene, such as might be required in films with science-fiction themes, often find it desirable to freeze the action in the scene while recording the scene with a moving motion picture camera. Scenes so recorded convey the sense of time passing for the viewer, as is naturally inferred from the camera movement, while time appears stopped for the subject.




Freezing the scene artificially is generally done by making models of any subjects within the scene that would otherwise be in fluid motion and directing actors in the scene to freeze. This method of freezing a scene is obviously limited in scope by a number of factors, particularly if the scene is intended to contain dramatic action. Such factors include the model-maker's ability to portray objects such as fluid properties in motion and the actors' ability to pose without moving. This method is further limited if the scene is documentary in nature, if it involves extensive use of fluids, pyrotechnics, smoke, airborne objects, or other dynamic properties, or if one of the actors is a young child or an animal. In these latter cases, freezing the action artificially is often impossible.




Another, simpler, method of creating the illusion that time has stopped in a motion picture scene is the freeze-frame. The freeze-frame is an effect achieved by repeating a single frame of camera negative over a series of adjacent frames of a projection print. The resulting composite motion picture image contains absolutely no motion. The freeze-frame is used by some film directors to stop time, usually at a time in the motion picture after the viewer has become accustomed to the general motion and passage of time. By stopping time, the director allows the viewer to reflect on the events that lead up to the stopped moment, as well as the specific drama of that particular moment in time. The freeze-frame, however, is incapable of capturing camera movement, and therefore fails to convey the illusion that time has stopped for the subject of the motion picture but not for the viewer.




Although subjects have been photographed simultaneously throughout this century for the purpose of recording photographs in three dimensions (i.e., stereo photography), the prior art does not teach or suggest methods of simultaneous photography for the purpose of creating special time-stopping effects in otherwise conventional motion picture scenes. Nor does the prior art teach or suggest a system for producing virtual camera movement from a sequence of simultaneous still photographs.




Multiphotographic systems for producing three-dimensional images have been used in the past in a wide variety of other fields, including the following:

Hattori, U.S. Pat. No. 5,223,925, shows an autostereoscopic system that consists of a series of television cameras arranged horizontally that send their images to similarly arranged image output screens that project inverted parallax images through a series of lenses consisting of a first convex lens and then a large Fresnel convex lens.




Montes, U.S. Pat. No. 5,237,353, discloses a system for taking, reproducing, and projecting three-dimensional still or moving pictures in which the pictures are taken by groups of two cameras arranged so that their lenses are at right angles and have a semitransparent plate disposed therebetween at a 45-degree angle. The pictures obtained from these groups of cameras are arranged on a single piece of film, which can then be copied or projected, the projection necessitating the use of one-third as many projection lenses as cameras.




In addition to the multiphotographic systems for producing three-dimensional images discussed above, prior art exists in the field of image processing for electronically simulating the pan, tilt, rotation, and zoom characteristics of a conventional camera using a single image. For example, U.S. Pat. No. 5,359,363 of Kuban et al. discloses a omniview motionless camera surveillance system that uses a wide angle lens to capture a circular image of an entire field of view in the memory of the device. High speed electronic circuitry can then be employed to view and manipulate a region of interest within the image. The device can accomplish the functions of pan, tilt, rotation, and zoom throughout the field of view without the need for any mechanical mechanisms to move the camera.




SOLUTION TO THE PROBLEM




None of the prior art references uncovered in the search show a system for freezing a scene in a moving picture while providing the illusion that the camera is moving in space three dimensionally around the frozen image. The present invention solves this problem by deploying an array of cameras along a preselected path, with each camera focused on a common scene. The cameras simultaneously record a plurality of still images of the scene, and the images thus recorded are transferred in a preselected order to a sequence of frames in a motion picture medium, such as motion picture film or video tape. Because each frame shows the common scene from a different viewpoint, placing the frames in sequence gives the illusion that one camera has moved around a frozen scene (i.e., virtual camera motion). The direction of motion depends on the preselected path chosen, which may be a straight line or any type of curve over which the array of cameras can be deployed.




Although multiple simultaneous synchronous motion picture cameras are found in the prior art for the purpose of recording three-dimensional motion pictures, none of the prior art references provide a system for combining virtual camera motion (as described above) with motion picture images showing time progression of the scene. A second embodiment of the present invention employs a two-dimensional array of video cameras, each of which synchronously captures a series of images in rapid succession over time. The resulting array of images can be combined in any order to create motion pictures having any desired combination of virtual camera motion and time-sequence images.




SUMMARY OF THE INVENTION




The present invention provides a system for recording virtual camera movement with respect to a subject at a fixed instant in time. The system uses an array of specialized modular cameras capable of simultaneously recording a number of photographic images of a scene from a number of laterally disposed positions. The system thus produces a series of still photographs that, when viewed in rapid succession as a motion picture, convey the illusion of lateral camera movement with respect to the recorded scene, while the subject of the recorded scene appears stopped in time.




In one embodiment, the system is formed of a number of still cameras designed to couple with one another so as to provide a continuous light-tight path for a length of photographic film to pass through the entire assemblage of cameras across each camera's focal plane. The system further has a shutter system capable of exposing the film inside all of the cameras simultaneously, light-tight connections for the film to pass to and from film magazines at each end of the assemblage of cameras, a system for advancing the film through the assemblage of cameras from one magazine to another, and a mechanism for moving the entire assemblage in any desired direction during the simultaneous exposure event. Alternatively, an array of video still cameras can be used. The images obtained are subsequently sequentially arranged in a preselected order onto a sequence of frames on motion picture film or video tape. When the motion picture medium is viewed, it appears as though the scene has frozen in time, while the camera appears to move around the frozen subject or scene. In another embodiment, an array of video cameras is used. Each camera in the array synchronously captures a series of images in rapid succession over time. The resulting array of images can be combined and sequenced in any order to create motion pictures having a combination of virtual camera motion and time-sequence images.




A primary object of the present invention is to provide a system that is able to freeze a scene in a motion picture yet provide the illusion of camera movement with respect to the frozen scene.




Another object of the invention is to provide a system that is capable of combining virtual camera motion with motion picture images showing time progression of the scene.




Yet another object of the present invention is to provide a system for freezing a scene in a motion picture in which the images comprising the frozen scene embody a blur caused by the movement of the cameras while recording the frozen scene. The motion blur smooths the transition from frame to frame when the motion picture image is reconstituted for viewing by the human eye.




These and other advantages, features, and objects of the present invention will be more readily understood in view of the following detailed description and the drawings.

DETAILED DESCRIPTION OF THE INVENTION




Turning to

FIG. 1

, an array of cameras


10


of the present invention is seen focused on a common scene


12


. A scene


12


as used in this description is not limited to a single point or object but comprehends an entire view or area. The cameras


10


are deployed as desired to achieve a certain effect along a preselected path, for example, a straight line, a concave arcuate path, or a convex arcuate path. As discussed in more detail below, the shape of the path chosen is limited only by the necessity to maintain a light-tight connection between adjacent cameras


10


. As with many methods of recording motion pictures, the present invention can be implemented with both photographic film and videotape. Both means of recording motion pictures (photographic film or videotape) are based on the principle of recording and reconstituting multiple frames of still image information in rapid succession continuously over time. Therefore, references to photographic film and motion picture medium are used herein to refer to motion pictures recorded with both photographic emulsion and video recording and storing means, although distinctions between film and videotape are made throughout to indicate the preferred method. Accordingly, it should be evident that either still cameras, video cameras, or motion picture cameras can be used in the array of cameras


10


of the present invention.





FIG. 2

shows a cross section of a single camera


10


of one embodiment of the present invention. The camera


10


is a simple box camera for obtaining still photographs. Light


28


enters the lens


24


and exposes the film


20


at the focal plane


26


. A shutter


22


is used to control access of the light


28


to the film


20


. It is to be understood that other types of cameras can be used in the present invention, as will be evident to those skilled in the art, for example, motion picture cameras or video cameras, and that the present invention is not meant to be limited to the description of the embodiment shown in FIG.

.




Illustrated in

FIG. 3

is an overview of an array of cameras


10


in accordance with the present invention. A series of cameras


10


, C


1


to C


N


, are arrayed side-by-side. The number C


N


of cameras


10


can be varied to suit the needs of the effect one desires to obtain. The cameras


10


are flexibly connected such that a single strip of film


20


passes through all the cameras


10


, as can be better appreciated by viewing FIGS.


7


(


a


) and


7


(


b


), and as is discussed in more detail below. The film


20


is stored in a first film magazine


30


at one end of the array of cameras


10


and taken up by a second film magazine


32


at the other end of the array of cameras


10


. The take-up mechanism


34


can be any conventional mechanism used for taking up film, such as a hand-cranked or machine-driven reel. A shutter release


36


simultaneously controls the shutters


22


for all the cameras


10


in the array. In the preferred embodiment, the shutter release


36


is a mechanical spring-loaded pneumatic cylinder using a variable aperture exhaust port to retard the speed of the cocked spring pulling the shutter.




The entire array of cameras


10


of the present invention can be moved in any desired direction, for example, laterally as shown by arrow


38


, in order to record motion during the simultaneous exposure event. In addition, the flexible array may be attached to a track to maintain the proper optical axis orientation of each module as the array is pushed or pulled to introduce motion blur along a tracking path that is nonlinear and noncircular. The motion blur helps smooth the transition from frame to frame when the motion picture image is reconstituted for viewing by the human eye.





FIGS. 4 and 5

show a single camera


10


of the present invention. The array of cameras


10


is held tightly together by the tension cables


40


, which run through the entire array parallel to and in the same plane as the shutter


22


. The shutter


22


is located in a shutter guide


42


. The top of the shutter guide


44


serves both to hold the shutter


22


in the shutter guide


42


and to guide the flexible tension cables


40


that hold each camera


10


in place in the array. The lens holder


46


, while fulfilling its primary role of supporting the lens


24


, also acts to guide and secure the tension cables


40


to the camera body. The body


48


of the camera


10


is fitted onto a base


49


having the focal plane


26


therein. A film guide


50


placed between the body


48


and the focal plane


26


holds the film


20


in the correct position against the focal plane


26


. The top of the shutter guide


44


and the shutter guide


42


each contain an aperture


52


,


54


directing the light path


28


from the lens


24


to the focal plane


26


.




Simultaneity of the shutter


22


release for each camera


10


is achieved in the preferred embodiment by means of a PTFE-coated strip of semi-rigid opaque black film having identical shutter openings


23


cut at intervals equal to the distance between the equidistant lenses of the cameras. This shutter strip


22


travels freely along a path parallel to the film path inside the cameras


10


, passing through each camera


10


through the shutter guide


42


on a plane between the camera's lens


24


and aperture


54


. The simultaneous exposure event occurs when the shutter strip


22


is pulled a distance less than the distance between two shutter openings


23


(provided this movement starts and stops with the shutter openings


23


out of alignment with the camera apertures


54


), so that exactly one shutter opening


23


passes in front of each aperture


54


during the event being recorded. This results in a simultaneous and identical time-length exposure of the film


20


inside each of the cameras


10


in the array. The shutter strip


22


could be pulled by, for example, a spring-loaded pneumatic cylinder


36


as discussed above and illustrated in FIG.


3


. It should be understood that other systems of shutters providing simultaneity will be evident to those skilled in the art. After each simultaneous exposure event, the film


20


contained inside the array of cameras


10


is advanced into the second magazine


32


, pulling a fresh strip of unexposed film


20


out of the first magazine


30


and into the array of cameras


10


, which are then ready for the next simultaneous exposure event.




The light-tight coupling between cameras


10


comprises a telescoping, double-overlapping light-tight connection, as shown in FIGS.


6


and


7


(


a


) and


7


(


b


). At one side of the camera


10


are found two flanges


60


and


61


on either side of the film


20


that are inserted in corresponding spaces


62


and


63


on an adjacent camera


10


as shown in FIG.


7


(


a


). The size of spaces


62


and


63


is exaggerated in the figures for ease of viewing. Space


63


is formed by two flanges


64


and


65


. Flange


61


has at its outermost edge an outward-protruding lip


67


. Flange


65


has at its outermost edge an inward-protruding lip


66


. When two cameras


10


are situated adjacently as shown in FIG.


7


(


a


), the outward-protruding lip


67


fits into space


63


over flange


65


and the inward-protruding lip


66


, forming a light-tight connection beneath the path of the film


20


. Another light-tight connection is formed by the insertion of flange


60


into space


62


above the path of the film


20


. A further light-tight flexible joint is formed on the shutter plane around the shutter strip


22


by the juxtaposition of flanges


70


,


71


,


72


, and


73


.




A further advantage of the light-tight connections described above for the preferred embodiment of the present invention is their ability to remain light-tight when the array of cameras


10


is deployed on an arc or circle as described above in FIG.


1


and as shown in more detail FIG.


7


(


b


). FIG.


7


(


a


) shows the array deployed on a straight line, whereas FIG.


7


(


b


) illustrates the changes that occur when the array of cameras


10


is curved on an arc. As the shutter


22


moves a distance A (as shown by arrows


74


), the outward-protruding lip


67


moves a distance B (as shown by arrows


75


) until it abuts the inward-protruding lip


66


, at which point further telescoping of the connection is prevented. The overlapping lips


66


and


67


maintain the light-tight integrity of the connection during the deployment of the cameras


10


on an arc.




FIGS.


8


(


a


) and


8


(


b


) illustrate the images recorded by a straight-line array of cameras


10


. The cameras


10


(


80


through


84


) are positioned to record a common scene


12


. The dotted lines show the light path


28


seen by each camera


10


. During a simultaneous recording event, each camera


10


records an image on the strip of film


20


, as shown by images


80


through


84


in FIG.


8


(


b


). As a result of the placement of each camera


10


(


80


through


84


), the perspective of each image


80


through


84


recorded shifts so that when the frames


80


through


84


are viewed in succession in, for instance, a motion picture, the viewer has the impression that a single motion picture camera is moving around the scene


12


while the scene


12


remains frozen in time.




The process that moves the images recorded by the cameras


10


of the system of the present invention from the film


20


to a motion picture medium, either motion picture film or videotape, is illustrated in

FIG. 9. A

series of negatives are recorded on the film


20


. During the process that moves the negatives from the film


20


to the final motion picture medium, each negative is rotated 90 degrees as shown in FIG.


9


and placed in the order desired on a motion picture or video medium


90


that will eventually be part of a motion picture. The process can be performed by optically transferring and rotating the film negatives in the conventional manner. Alternatively, the process can be performed as illustrated in FIG.


10


. An original camera negative


1002


is digitized onto a photo compact disk


1004


(CD). The CD


1004


is then accessed by use of a computer workstation


1006


, where the digitized images


1002


are rotated or otherwise manipulated and then assembled to achieve the effect of virtual camera motion. Finally, the assembled images are recorded to motion picture film or videotape


1008


. A system currently available for performing the process described above is the Kodak Cineon digital film system of the Eastman Kodak Co., Rochester, N.Y.




It should be noted that other digital storage mediums, such as magnetic or optical disks, could be used to store images in place of photo compact disks. Random access devices, such as magnetic or optical disks, provide great flexibility for the user in selecting, combining, and editing images. Random access devices also facilitate creation of multimedia applications incorporating image sequences. Interactive computer applications often use image sequences in a non-linear manner, unlike conventional motion pictures or videotape.




The present system is capable of recording a series of simultaneous exposure events over time, in addition to recording a single simultaneous exposure event. Specifically, the method, when utilized in rapid succession, records forward-in-time sequences of images that embody a recordation of the advance of time within the scene, as well as lateral-in-space sequences of images that embody a recordation of lateral virtual camera movement. The time base of the lateral virtual camera movement is independent of the time base of the scene itself. Such a time-series of images would present the effect, when selected and sequenced into a motion picture or video medium as described in more detail below, of showing advancing time in the scene in addition to lateral virtual camera motion.




A second embodiment of the present invention is illustrated in

FIGS. 11 through 14

. The apparatus of the second embodiment employs an array of video cameras


1100


as shown in

FIG. 11

capable of recording a plurality of photographic images of a scene from a plurality of positions simultaneously and synchronously in rapid succession over time. Compared with the first embodiment, the user can choose any sequence of images desired from the array of recorded images. This provides the user with complete flexibility to combine images from any of the cameras in the array


1100


, including sequences recorded along a path within the camera array at a fixed point in time, as in the first embodiment. For example, the user can select a sequence of fixed-in-time images from a single row or column of individual cameras or any other desired pattern available within the array shown in FIG.


11


. The user can also select forward-in-time sequences of images from selected cameras, or backward-in-time sequences, or any other combination of fixed-in-time and time-sequence images. This embodiment allows user-controllable virtual camera movement with the respect to the scene as time advances.




Each individual video camera


1102


, illustrated in

FIG. 12

, captures an extremely wide field of view, as shown by arrows


1200


, that is recorded digitally and that can be electronically zoomed, panned, and tilted, or otherwise edited as desired after recordation. To form the array of video cameras, each individual camera


1102


is mounted in a receptacle


1400


as shown in

FIG. 14

having a plurality of holes


1402


cut therein to receive the cameras


1102


. Each hole


1402


has a tongue


1404


extending toward its center that matches a corresponding groove


1302


cut into the casing

of each video camera

.




This flexibility enables the system of the second embodiment of the present invention to generate virtual camera movement in nearly any direction rather than simply along a linear path as described above for the preferred embodiment. Here again, the entire array of images can be stored on a random access storage device to simplify selection, editing and sequencing by the user.




The above disclosure sets forth a number of embodiments of the present invention. Other arrangements or embodiments, not precisely set forth, could be practiced under the teachings of the present invention and as set forth in the following claims.



Claims
  • 1. A motion picture made by a process comprising the steps of:providing an array of cameras deployed along a preselected path with each camera focused on a common scene; triggering each of the cameras to substantially simultaneously record a still image of the scene; transferring the still images in a preselected order along the path into a time-sequence of frames; and outputting the time-sequence of frames in a motion picture medium, thereby creating the illusion that a single motion picture camera has moved along the path.
  • 2. The motion picture of claim 1 wherein at least one camera comprises a video camera.
  • 3. The motion picture of claim 1 wherein the cameras record the images on photographic film.
  • 4. The motion picture of claim 1 wherein the motion picture medium comprises a video storage medium.
  • 5. The motion picture of claim 1 wherein the motion picture medium comprises motion picture film.
  • 6. The motion picture of claim 1 wherein the array of cameras is two dimensional.
  • 7. The motion picture of claim 1 wherein the still images are transferred in the form of digital data in a preselected order along the path into the time-sequence of frames.
  • 8. A motion picture made by a process comprising the steps of:providing an array of cameras deployed along a preselected path with each camera focused on a common scene; triggering each of said cameras to substantially simultaneously record a still image of the scene; transferring the still images from the cameras into a digital data format; transferring the digital data into a time-sequence of frames; and outputting the time-sequence of frames in a motion picture medium, thereby creating the illusion that a single motion picture camera has moved along the path.
  • 9. The motion picture of claim 8 wherein at least one camera comprises a video camera.
  • 10. The motion picture of claim 8 wherein the cameras record the images on photographic film.
  • 11. The motion picture of claim 8 wherein the motion picture medium comprises a video storage medium.
  • 12. The motion picture of claim 8 wherein the motion picture medium comprises motion picture film.
  • 13. The motion picture of claim 8 wherein the array of cameras is two dimensional.
