    Abstract: A compact light source for an optical color correction system selectably removes under electronic control zero, one, two, or all three primary color components from an input beam of white light. The system polarizes the input beam linearly and passes it through three filter assemblies. Each filter assembly comprises a half-wave plate whose optic axis may be rotated between two different positions under electronic control and a colored polarizer. With the optic axis in one position, the half-wave plate passes the incoming polarized light unaltered. With the optic axis in a second position, the half-wave plate rotates the incoming polarized light. The colored polarizer removes a primary color component only when the light passing through it is polarized along its principal axis, and passes the incoming light unaltered when that light is polarized along the orthogonal axis.

  • Patent number: 6091776
    Abstract: A process and apparatus for encoding are provided, wherein fields of a digital signal are processed to detect repeat fields. Adjacent pairs of the non-repeated fields are organized into frames. A determination is made whether to encode each of the frames as an intraframe, a predicted frame or a bidirectionally predicted frame. The frames are encoded in a specific, predefined order relative to the order of capture of the frames and the type of frame. After each bidirectionally predicted frame that immediately precedes one of the detected repeat fields, encoding of a frame is delayed for one field time. Encoding is paused after encoding each reference frame that is the very next reference frame to be encoded after a second reference frame, which second reference frame immediately precedes one of the detected repeat fields. A process and apparatus for statistically multiplexing multiple encoded digital video signals are also provided.

  • Patent number: 6088544
    Abstract: A photographic and video image system for transforming an image on a frame of a photographic film includes a structure in the overall form of a photographic printer having an image transformation element that transforms an optical image from the film into a video signal. A frame position indicator, which can be a hole or an optical or magnetic signal, is recorded on the film along with aspect information relating to the size of the frame exposed on the film. The frame position indicator and aspect information are detected and used to control a film feeding operation in the optical image to video signal transformation operation. The user of the system can record order information on the film that is used to specify the aspect of the resultant photographic print, as well as the quantity of prints to be made. Such order information can be superimposed as a menu on a displayed video signal at the time the video signal is reviewed prior to producing a photographic print.

  • Patent number: 6067109
    Abstract: An image reading method which can achieve highly accurate image reading with no color balance lost regardless of the type of recording media, that is, whether a film is a negative film or a reversal film, and thus is able to obtain in a stable manner a reproduced image of higher quality having excellent color balance and density balance. A reading light beam is irradiated on a transparent-type original, the transmitted light of the transparent-type original is separated into the three primary colors and is read by means of an photoelectric transducer device. If the transparent-type original is a negative film, then the adjustments of the transmitted light reading by the photoelectric transducer device are made respectively in the three primary colors independently of one another and, if the transparent-type original is a reversal film, then the adjustments of the transmitted light reading by the photoelectric transducer device are made uniformly in all of the three primary colors.

  • Patent number: 6064427
    Abstract: When a reprint of a picture which has been printed once and stored as picture image data is requested under a different condition, the reprint can be generated without carrying out rereading of a film. When film reading for generating a print is carried out, as much information showing the content of the picture image is recorded on the film as possible. This includes information which is not necessary for generating the requested print. It is stored as a portion of the picture image data. In this manner, even when a reprint under a condition different from the previous printing is requested, the print can be generated by reading necessary content from the stored picture image data.
