Abstract
The present invention in its first aspect provides a display apparatus including a light emitting apparatus having a plurality of light sources, a brightness sensor that measures an emission brightness of the light emitting apparatus corresponding to each of blocks, a temperature sensor that measures a temperature of the light emitting apparatus corresponding to each of the blocks, an acquisition unit that acquires the measured value of the temperature sensor for each of the blocks, and an emission brightness control unit that performs processing of acquiring the measured value of the brightness sensor and controlling the emission brightness based on the measured value of the brightness sensor, in order from a block with a greatest difference between a temperature represented by the measured value acquired by the acquisition unit and a temperature represented by the measured value acquired in the past by the acquisition unit.
