Abstract
A brightness converting unit obtains brightness of each of the pixels. The low-resolution brightness image generating unit divides an image based on the input image signal into a plurality of domains, and obtains an average brightness of each of the domains, on the basis of the brightness obtained by the brightness converting unit. A high-resolution brightness image generating unit obtains brightness of each of the pixels included in the image based on the input image signal by weighting the average brightness obtained for each of the domains by a distance from a central portion of the domain. On the basis of the obtained brightness, the corrected gain lookup table determines a corrected gain, and the correcting unit corrects the input image signal.
