摘要:
A light emission control device includes a partial region feature quantity detector, an enlarged region feature quantity detector, a whole screen feature quantity detector, and a light emission controller. The partial region feature quantity detector detects a feature quantity of the image as a partial region feature quantity. The enlarged region feature quantity detector defines the partial region of interest and the partial regions neighboring the partial region of interest, and detects a feature quantity of the image of the enlarged region. The whole screen feature quantity detector detects this feature quantity as a whole screen feature quantity. On the basis of the partial region feature quantity and the enlarged region feature quantity pertaining to the partial region of interest, and the whole screen feature quantity, the light emission controller controls the light emission luminance of the light emission unit corresponding to the partial region of interest.
