Abstract: The present invention provides a technique for performing gamma correction processing when there are a plurality of characteristic areas, each of which is characterized by the high frequency in a luminance histogram to improve the impression of contrast. According to the present invention, a luminance characteristic detector (4) detects the luminance of an input image signal and a microcomputer (5) calculates an APL and a luminance histogram of an input image signal. A gamma correction circuit (6) performs the gamma correction processing in response to the luminosity of the input image signal by use of the result of the calculation carried out by the microcomputer (5). Then, if there are a plurality of characteristic areas, each of which is characterized by the high frequency in the luminance histogram, a characteristic emphasis circuit (7) performs grayscale extension processing for the plurality of characteristic areas. This makes it possible to perform the most suitable processing in response to the input image signal so that the impression of contrast is improved.

Abstract: In a liquid crystal device, an in-region gradation value detection section detects gradation levels of input video signals on every sub-region, removing gradation levels of pixels within a predetermined upper range (m %) from the brightest gradation level in the sub-region to detect the maximum in-region gradation level Pa. A boundary gradation value detecting section removes gradation levels for pixels within a predetermined upper range (n %) from the brightest gradation level for pixel groups belonging to the region boundary portion in the sub-region to detect the maximum boundary gradation level Pb. A backlight control value deciding section selects higher one of the level Pa and the level Pb as the maximum gradation level Pc in the sub-region, and decides a backlight control value K based on the ratio between the level Pc and the upper limit value Pmax of the gradation level.

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 translation: 即使在播放过程中跳过广告，也能够同时进行记录和回放的设备允许商业广告保留其广告功能。 通过数字水印，将CM替代数据嵌入到从广播电台广播的视频信号中的节目数据中。 CM替代数据将显示信息，如显示的特定赞助商名称和商品名称。 视频记录/回放设备包括可随机访问的存储单元并且具有同时的记录/重放能力。 如果商业视频被跳过并且不通过播放呈现，则CM替代信息被叠加在与商业相关联的节目的渲染视频上。 因此，可以保留商业广告功能。
