Abstract:
1. A display device, comprising: a display panel which displays an image; a backlight unit which is disposed on a back surface of the display panel, and which includes a plurality of light sources for each region obtained by dividing the display panel into a plurality of regions; a first detection unit which detects, for an image of each of the divided regions, an average value of brightness, a maximum value of brightness, and a color area of a specific color, as a characteristic amount of the image of each of the divided regions; a second detection unit which detects, for an image of the overall display panel, a variance value of brightness, as a characteristic amount of the image of the overall display panel; and a drive unit which determines an emission brightness of each of respective light sources, of the plurality of the light sources corresponding to each of the regions, based on the characteristic amount of the image of each region that is detected by the first detection unit, and the characteristic amount of the image of the overall display panel that is detected by the second detection unit, and drives each of the respective light sources to emit light at the determined emission brightness, and wherein the drive unit includes:
