Abstract: A system is disclosed in which individual black & white frames from film (100) are colorized by combination with color film (120) generated by computer (110) assisted techniques. Color information is processed, for example, by filtering, cross-dissolving or interpolation. The technique is also applicable to modifying the color of black & white portions of full color film (340) to repair damaged or degraded frames or to create special effects.

Abstract: Methods and apparatus for motion estimation in motion picture processing are disclosed in which an initial velocity vector is selected as an estimation of the displacement of a region from a location in a first frame to a corresponding location in a second frame and the velocity estimate is then refined by minimizing an average value of the squared directional gradient residual over the region. A continuous signal representation is obtained from a set of image intensity samples over the region of interest and, from tThe U.S. government has rights in this invention pursuant to NSF Grant No. DC1-8407285.

Abstract: A system is disclosed in which individual frames are colorized by the addition of manually generated color. Color information is blurred, for example, by passing through a low resolution digital encoder for use in frames adjacent to the one being individually colorized. Interpolative techniques are used to reduce the number of frames which have to be individually colorized.

Abstract: My invention relates to photographing scenes with standard motion picture photographic equipment where multiple views of a subject are photographed while the subject rests on a moving turntable and the stationary camera has its optical axis pointed at the turntable rotation axis or where the subject is stationary and the camera effectively moves in an arc about an axis located between the camera and scene.The surface of the processed film (or other appropriate media) is arrayed in a vertical plane and constrained to move horizontally around a portion of a circle. Film images are scanned by a light source and radially projected in a direction away from a vertical rotation axis. Concentric with the vertical axis are the semi-specular screen of radius R and the scanning projector circle of radius close to R/3. The screen reflects projected light in a horizontal plane and scatters projected light in a vertical plane.

Abstract: A system is disclosed for producing a colored-motion picture film from a black-and-white source film. Each frame of the black-and-white film is projected as an image onto a work surface to which colors are applied within selected areas for combination with the projected black-and-white image to provide a color composite. The color composite is then photographed with color sensitive film. The black-and-white film is processed frame-by-frame, preserving registration from one frame to the next (in a sequence) with the colored format which is accordingly modified to a limited extent to produce each composite that is photographed.

Abstract: A method production of a composite photograph containing at least two images, i.e. a mark image and a holder image, and a method for distinguishing images in said composite photograph, said photograph being composed of alternate strips containing elements of the holder identify photograph and strips containing elements of validity check mark photograph, all strips being disposed at equal intervals from one another, and said photograph of the holder being hidden by said check mark photograph when viewed normally, and to be discernible only when viewed through a lenticular lens.

Abstract: The method of producing a colored film from an exposed black-and-white picture and especially from an exposed black-and-white motion picture film wherein a black-and-white image is projected onto a surface, opaque pastel colors are applied within selected areas of the projected image and the reflected colored composite, of the opaque pastel colors and the black-and-white image superimposed thereon, is then photographed with color-sensitive film.

Abstract: A sound motion-picture system employing a film handling cassette within which the film is retained throughout all photographic and audio operations. The film handling cassette includes both an audio station and an exposure-projection station, and the camera and viewer apparatus includes a pair of drive arrangements for progressively advancing incremental sections of such film across the exposure-projection station and for substantially uniformly advancing the film strip through the audio station. To isolate these different film motions, the drive arrangements cooperate with the cassette to provide a free loop of film extending exteriorly of the cassette. A sensing element monitors the loop of film and adjusts one of the drives so as to retain the loop within predetermined limits. In the camera, the audio drive is coupled to the start switch so as to displace the audio drive into a standby position when the camera is not being operated.
