Abstract
A display apparatus includes light-emitting units, a liquid crystal panel, a representative luminance acquisition unit for acquiring luminance values of the light-emitting units, an HPF processing unit for acquiring HPF luminance values of the light-emitting units by increasing the luminance value of a target light-emitting unit, which is greater than that of a neighboring light-emitting unit, according to a difference of the luminance value of the target light-emitting unit and that of the neighboring light-emitting unit, a smoothing processing unit for acquiring correction luminance values of the light-emitting units by increasing the HPF luminance value of a target light-emitting unit, which is smaller than that of a neighboring light-emitting unit, according to a difference of the HPF luminance value of the target light-emitting unit and that of the neighboring light-emitting unit, and a light-emission control unit for controlling light emission of the light-emitting units using the correction luminance values.
