Patent ID: 7928957

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 light-value calculator configured to calculate a light value of each of the light sources for each of the light source areas; a light-value modifying module configured to modify a light value calculated by the light-value calculator for a target area to a modified light value using light values for surrounding areas, the target area being one of the light source areas for which a light value is to be modified, and the surrounding areas being light source areas around the target area; and a light controller configured to light a light source in the target area based on the modified light value, wherein the light-value modifying module includes a light-value reader configured to read the light value calculated by the light-value calculator for each of the light source areas, a filter configured to perform filtering on light values for the target area and the surrounding areas read as a read light value by the light-value reader to output a filtered light value, a comparator configured to compare the read light value and the filtered light value output from the filter, and a light-value setting module configured to set the modified light value based on a comparison result of the comparator.
