摘要： 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.

摘要： According to our invention, linked operation between a monitor apparatus for displaying images, and a set-top box for transmitting image signals to the monitor apparatus via a required interface, can be achieved properly, even if both units are constructed in casings separate from each other. The monitor apparatus uses a CEC line to transmit a CEC vendor command including at least a code associated with unit information, and the set-top box apparatus transmits the CEC vendor command including at least the code associated with the unit information. Upon receiving the vendor command from the set-top box apparatus, the monitor apparatus switches to the linked operation with the set-top box.

摘要： In a liquid-crystal display device including an edge-light-scheme-employed backlight device, it is implemented to reduce its power consumption while maintaining its excellent picture-quality. The present invention is applied to the backlight device with a plurality of edge-light-scheme backlight cells in a matrix-like manner including a LED light-source, and a light-guiding plate for emitting light. The intensity of light from a backlight cell positioned at a screen's peripheral portion is so controlled as to be made lower than the intensity of light from a backlight cell at a central portion. The light intensity of a backlight cell having a LED light-source adjacent to a first edge portion of the illumination surface of the backlight device is so controlled as to be made higher than the light intensity of a backlight cell adjacent to a second edge portion opposed to the first edge portion.

摘要： An image display device using the area control method for eliminating irregularities as seen from the side and also capable of lowering power consumption. The degree of flatness indicating the image flatness of an image in each image area is calculated, and in areas that are flat the light source luminance is set high in order to lessen irregularities as seen from the side; and in areas that are not flat the irregularities are difficult to perceive as seen from the side so an effect that cuts power consumption is obtained without having to correct the light source luminance.

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： 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.

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.
