Abstract: A backlight of a liquid crystal display device is divided into a plurality of regions. A backlight area dimmer sets a dimming value for each of the regions of the backlight according to a characteristic amount of the input image. A backlight dimming limiter sets an upper limit and lower limit of the dimming value set by the backlight area dimmer. In this case, the backlight dimming limiter may set the upper and lower limits of the dimming value according to a combination of at least two pieces of information among illuminance information on the external light, category information on the input image and image mode information set by the user.

Abstract: 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.

Abstract: An image display apparatus includes a dimming value determination circuit for determining a dimming value of a backlight based on an input image signal, an image signal compensation circuit for compensating the input image signal supplied to a liquid crystal panel in accordance with the dimming value, and a backlight drive circuit for driving and controlling the backlight in accordance with the dimming value. When the light emitting luminance of the present frame of the backlight increases relative to the light emitting luminance of the previous frame, the backlight drive circuit delays the timing for applying the dimming value of the present frame. This makes it possible to reduce power consumption of the backlight by suppressing deterioration in the image quality in spite of the sharp change in the display image luminance.

Abstract: A technique is provided for using, in a wireless video transmission device and a plurality of wireless video reception devices which intermittently perform signal reception processing within standby periods, a human body detection unit to accelerate the start-up of the wireless video transmission and reception devices. When the presence of a person is detected by the human body detector, a person detection signal is sent to a wireless video reception device or the transmission device 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 and also reducing standby power thereof.

Abstract: A technique is offered which is applied to a system for wirelessly sending and receiving control commands and which permits mutual communications owing to the control commands between a wireless video transmitter and wireless video receivers to be operated stably with low delay. The transmitter makes a decision as to whether commands received from the receivers are certain commands. If so, the transmitter assigns transmissible periods, in which the receivers can send commands, more preferentially to the wireless video receiver that has sent out the certain commands than the other wireless video receivers.
