Abstract
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 light-value calculator, a light-value modifying module, and a light controller. The light-value calculator calculates a light value for each of the light source areas. The light source areas include a target area for which a light value is to be modified and surrounding areas surrounding the target area. The light-value modifying module modifies a light value calculated for the target area using light values for the surrounding areas. The light controller lights a light source in the target area based on the modified light value.
