Abstract
A display apparatus includes: a light emission unit including a plurality of light sources that emit light; a display unit displays an image by modulating the light on the basis of frames; a determination unit determines a luminescence intensity of each of the light sources for each sub-frame; and a control unit controls lighting of each of the light sources for each sub-frame at the luminescence intensity, wherein the determination unit (1) determines a leakage light quantity, wherein the leakage light quantity is a transmission quantity of light from other light sources that is generated due to response delay in modulation by the display unit, for each region of the display unit corresponding to each of the light sources, and (2) determines the luminescence intensity in accordance with the difference of the leakage light quantity between the regions.
