Patent ID: 8159451

Claim:
A light-emission control device that controls light emission of a plurality of light sources of a light emitter that illuminates a liquid crystal panel, the light emitter including a plurality of light source areas in each of which is arranged one of the light sources, the light-emission control device comprising: a virtual light-value calculator configured to calculate a virtual light value for each virtual light source area that includes one of the light source areas and a virtual area obtained by virtually dividing the light emitter into areas different in size from the light source areas; a light-value calculator configured to calculate a light value of one of the light sources corresponding to the one of the light source areas based on the virtual light value calculated by the virtual light-value calculator; and a light controller configured to light the one of the light sources based on the light value calculated by the light-value calculator, wherein the light-value calculator calculates the light value based on any one of a maximum luminance value and an average luminance value in the virtual light source area while reflecting luminance information of the virtual area in calculation of the light value.
