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.

Claims

1. A system for producing virtual camera motion in a motion picture medium comprising:

a strip of photographic film;

a first magazine for holding said photographic film prior to exposure;

a second magazine for holding said photographic film after exposure;

an array of cameras deployed along a preselected path with each camera having a focal plane and a lens assembly for focusing an image of a common scene onto said focal plane;

means for triggering each of said cameras to simultaneously record a still image of said scene by exposing a portion of said film along said focal plane;

film feeding means for feeding said strip of film from said first magazine through each of said cameras so that a portion of said film is disposed at said focal plane of each camera, and for feeding said strip of film from each of said cameras into said second magazine; and

means for transferring said images from said film in a preselected order along said path onto a sequence of frames in said motion picture medium.

2. The system of claim 1, wherein said film feeding means further comprises means for advancing said film from said first magazine through each of said cameras by a predetermined increment after said cameras have been triggered.

3. The system of claim 1, wherein said motion picture medium comprises motion picture film.

4. The system of claim 1, wherein said motion picture medium comprises video storage means.
