Abstract: A picture display technique carries out an adjustment of image quality of an inputted picture signal in response to a type of the inputted picture signal, e.g., a type of a first picture signal into which a second picture signal, having fewer scanning lines than that of the first picture signal, is converted, and an original type of the first picture signal, and then displays a picture of an adjusted picture signal on a display device. Further, the adjustment of the picture quality may include at least one of hue correction of the inputted picture signal in a certain hue range and chroma correction of the inputted picture signal in a certain chroma range. The adjustment of the picture quality may also include a contour correction of the inputted picture signal.

Abstract: A device enabling simultaneous recording and playback allows commercials to retain their advertisement function even if the commercials are skipped over during a playback process. By digital watermarking, CM-substitute data is embedded in program data among video signals broadcasted from a broadcast station. CM-substitute data is to present information such as a particular sponsor name and commodity name on display. The video recording/playback device includes a randomly accessible storage unit and has a simultaneous recording/playback capability. If commercial video is skipped over and is not rendered by playback, the CM-substitute information is superimposed on the rendered video of the program associated with the commercial. Thus, the commercial advertisement function can be retained.

Abstract: A multiple-exposure apparatus in a graphic arts copying machine of a slit-exposure type includes an original holding member mounted for horizontal reciprocating motion. An optical exposure system exposes an optical image of a slitwise segment of the original onto a photosensitive material. A moving device reciprocates the holding member and conveys the photosensitive material relative to the optical system. The moving device is adapted to synchronize the advance of the original holding member and the conveyance of the photosensitive material. A data setting device is provided for setting predetermined data concerning a predetermined multiple-exposure layout mode of the original onto the photosensitive material. A control unit controls the operation of the optical exposure system by enabling and disabling the exposure by the optical system and also synchronizes the moving device in an associated relationship as a function of the predetermined set data.
