Abstract: An image processing unit includes: a gain calculating section obtaining, based on first luminance information for each pixel, a first gain, in which the first gain is configured to increase with an increase in pixel luminance value in a range where the pixel luminance value is equal to or larger than a predetermined luminance value, and in which the pixel luminance value is derived from the first luminance information; and a determination section determining, based on the first luminance information and the first gain, second luminance information for each of the pixels.

Abstract: A liquid crystal display includes: a light source unit that includes a light-guiding plate with a light-exit plane partitioned into emission subsections, and one or plural sides, and light sources; a liquid-crystal-display panel that includes pixels, and modulates light emitted from the light source unit, thereby performing image display; and a display control unit that includes a partitioning-drive processing section generating each of a light-emission pattern signal and a partitioning-drive image signal, performs light-emission driving for each light source, and performs display driving for each pixel. The partitioning-drive processing section performs a gain correction of multiplying each pixel signal in the input image signal by a predetermined gain factor that is set so that a value increases as a pixel position of the pixel signal goes away from the light source, and generates the light-emission pattern signal and the partitioning-drive image signal, by using gain-corrected pixel signal.
