According to one embodiment, a light-emission control device controls light emission of light sources of a light emitter including a plurality of light source areas each corresponding to one of the light sources, and includes a virtual light-value calculator, a light-value calculator, and a light controller. The virtual light-value calculator calculates a virtual light value for each virtual light source area including a light source area and a virtual area obtained by virtually dividing the light emitter into areas different in size from the light source areas. The light-value calculator calculates a light value of a light sources corresponding to the light source area based on the virtual light value. The light controller lights the light source based on the light value.
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 liquid-crystal display apparatus including a liquid crystal panel, a light emitter that includes a plurality of light source areas in each of which is arranged one of a plurality of light sources for illuminating the liquid crystal panel, and a light-emission control device that controls light emission of the light sources, the liquid-crystal display apparatus comprising:
