Abstract: 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.

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: A direct type backlight unit used in a liquid crystal display device is provided which can suppress lowering of luminance at an electrode portion of a linear light source. A reflecting plate is formed on a side wall of a box-shaped reflector close to an end of a linear light source. The reflector reflects light beams from the linear light source to be guided toward a liquid crystal panel. The reflecting plate on the side wall has at least two inclined surfaces. The inclined surfaces may have a stepped shape or a convex ridge shape. According to this arrangement, it is possible to reduce or eliminate decrease of the luminance level at ends of an effective display area of a liquid crystal panel.

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: An object of the present invention is to provide an image display technology with which high contrast can be stably obtained. In order to achieve the above object, the present invention changes the gain of a digital luminance signal by feeding back information on maximum and average luminance levels of the luminance signal, adjusts image contrast, and in accordance with the average luminance level detected from the feedback system, controls the illuminance of the backlight applied to a display unit. The control increases the illuminance of the backlight when the detected average luminance level is higher than the upper-limit value of a previously set reference range, and reduces the illuminance when the detected average luminance level is lower than the lower-limit value of the reference range.
