Abstract
An image display apparatus according to the present invention includes: a light-emitting unit capable of separately controlling the emission brightness in each of a plurality of divided regions in a screen; a determining unit configured to determine a target brightness of a predetermined divided region, based on image data corresponding to the predetermined divided region; an estimating unit configured to estimate the brightness of the predetermined divided region when light is emitted by the light-emitting unit at emission brightness which is based on image data in each of the plurality of divided regions; and a control unit configured to control the emission brightness of two or more divided regions including the predetermined divided region based on the difference between the target brightness determined by the determining unit and the brightness estimated by the estimating unit.
