Abstract

The present invention relates to a display control apparatus and method, and a program that are capable of appropriately controlling the luminance of light to be emitted by backlights with simple processing. On the basis of an input image signal, a peripheral-representative-value computation unit () computes, as a peripheral representative value, luminance that is output by backlights of a block of interest and blocks in the periphery thereof among the backlights formed from a plurality of blocks. A peripheral-contribution-amount computation unit () divides the peripheral representative value by light-emission efficiency based on a light-emission profile that is an output luminance distribution when the block of interest emits light so as to compute the amount of peripheral contribution by peripheral blocks to the block of interest. A light-emission level computation unit () computes the backlight luminance as a light-emission level by dividing a necessary amount of light emission of the block of interest by the amount of peripheral contribution. The present invention can be applied to a display device, such as a liquid-crystal display.
