Abstract

See full text

An image processing device reduces power consumption of a backlight by lowering a dimming value through brightness distribution for pixels. The image data processing device includes: an image analyzing circuit configured to analyze original image data on a video image divided into a plurality of regions and calculate a representative brightness value for each region; a dimming value calculating circuit configured to calculate a dimming value for each region in order to adjust the brightness of a backlight according to the representative brightness value; a pixel analyzing circuit configured to analyze brightness distribution for a plurality of pixels in each region; a dimming control circuit configured to re-adjust the dimming value for one region according to the brightness distribution; and a dimming output circuit configured to output, to a backlight driving device, a dimming control signal for driving the backlight according to the dimming value.
