摘要： A disclosed technique for adjusting the image quality uses a moving picture for a sample stored in advance on a storage medium. A plurality of sample moving picture images, based on the moving picture for a sample read from the storage medium, having different image quality relative to each other are displayed on the screen. This technique enables confirmation of how the actual image having been subjected to the image quality adjustment would be displayed in an apparatus for displaying a moving image, such as a television receiver, because the sample stored on the storage medium is a moving picture.

摘要： 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.

摘要： The present invention provides a movement correction frame count transformation apparatus for carrying out frame count transformation processing on a picture signal. In the apparatus, an input picture signal (S1) of interlaced scanning is converted into a signal (S2) of sequential scanning by an IP conversion unit (1). A movement detecting unit (3) detects movement detection signals (MD1 and MD2). A block unit movement vector searching unit (4) detects a block unit movement vector (BMV) by carrying out block matching processing. A movement vector correcting unit (5) carries out miniblock division processing to generate a movement vector (BV) if a movement correction error is equal to or greater than a threshold value. A pixel unit movement vector generating unit (6) generates a movement vector with a smallest error component between a frame signal of a current frame and a frame signal of an immediately preceding frame as a movement vector of a pixel. An MC interpolation frame signal generating unit (7) generates an interpolation frame in movement correction processing carried out by a median filter in order to produce a signal (S4) of sequential scanning as a result of frame count transformation based on movement correction.
