摘要： An initial light control value calculation section (11) calculates the backlight's initial light control value K0 according to brightness of an inputted image signal (10) for each area. A black area measurement section (22) measures a black area S by obtaining ratio of the number of pixels satisfying Y ‰¤ Y0 (Y: brightness signal level, Y0: black level threshold) in the screen. A minimum light control value output section (25) determines a minimum light control value Kmin based on comparison between the measured black area S and a black area threshold S0 and outputs a maximum value permissible for the light control value as the value Kmin when the black area S is the threshold value S0 or less. An LED control signal calculation section (31) outputs a control signal to LED light sources based on a light control value K1 as the higher one of K0 and Kmin.

摘要： PROBLEM TO BE SOLVED: To provide a video transmission device which can precisely discriminate that a prescribed video signal source and a prescribed video display device are connected to input/output respectively. SOLUTION: The video transmission device includes: a first register which is set by receiving a CEC message which the video signal source issues by reading EDID of the video transmission device and is reset by a rise of 5V supplied from a video signal device; and a second register which is set by reading the EDID of the video display device and discriminating that the device is the prescribed video display device and is reset when a state that HPD is "L" continues for a prescribed period or above. Only when the first and second registers are both set, the prescribed video signal source, the video transmission device and the video display device are determined to be directly connected.

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 (12) in each image area is calculated (30), and in areas that are flat the light source (17) 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 technique is provided for using, in a wireless video transmission device (302) and a plurality of wireless video reception devices (306, 307, 308, 309) which intermittently perform signal reception processing within standby periods, a human body detection unit (17) to accelerate the start-up of the wireless video transmission and reception devices (302, 306-309). When the presence of a person is detected by the human body detector (17), a person detection signal is sent to a wireless video reception device (306) or the transmission device (302) to thereby limit usable communication channel candidates in number. The limited number of usable channel candidates are then used to perform intermittent signal reception, thereby shortening the searching time cycle of such intermittent reception within a standby period, thus lessening the startup time from the standby state between the wireless video transmission and reception devices (302, 306) and also reducing standby power thereof.
