Patent ID: 8786541

Claim:
A light emission control device for controlling light emission units irradiating respective ones of partial regions formed by dividing a display screen of an optical modulation unit for displaying an image by optically modulating illuminating light responsive to image data, such that light emission luminance of each of the partial regions can be controlled; said light emission control device comprising: a partial region feature quantity detector that defines each of the partial regions as a partial region of interest, and detects a feature quantity of the partial region of interest, as a partial region feature quantity; an enlarged region feature quantity detector that detects a feature quantity of an enlarged region including the partial region of interest, and a partial region neighboring the partial region of interest, as an enlarged region feature quantity pertaining to the partial region of interest, a whole screen feature quantity detector that detects a feature quantity of entirety of the image represented by the image data, as a whole screen feature quantity; and a light emission controller that controls light emission luminance of the light emission unit corresponding to the partial region of interest, on the basis of the partial region feature quantity pertaining to the partial region of interest, the enlarged region feature quantity pertaining to the partial region of interest, and the whole screen feature quantity.
