DISPLAY APPARATUS WITH LIGHTING DEVICE, CONTROL METHOD FOR DISPLAY APPARATUS, AND STORAGE MEDIUM

摘要

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.

1. A display apparatus comprising:
a plurality of light-emitting units configured to emit light; a display unit configured to display an image on a screen with transmitted light emitted based on an input image; a first acquisition unit configured to acquire initial luminance values of the plurality of light-emitting units based on the luminance of each of a plurality of regions of the input image corresponding to each of the plurality of light-emitting units; a first processing unit configured to acquire intermediate luminance values of the plurality of light-emitting units by correcting the initial luminance values of the plurality of light-emitting units; a second processing unit configured to acquire correct luminance values of the plurality of light-emitting units by correcting the intermediate luminance values of the plurality of light-emitting units; and a control unit configured to control light emission of each of the plurality of light-emitting units according to the correct luminance value of each of the plurality of light-emitting units, wherein, in a case where the initial luminance value of a first target light-emitting unit among the plurality of light-emitting units is greater than the initial luminance value of the first neighboring light-emitting unit neighboring the first target light-emitting unit, the first processing unit corrects by increasing the initial luminance value of a first target light-emitting unit according to a difference of the initial luminance value of a first target light-emitting unit and the initial luminance value of the first neighboring light-emitting unit, and wherein, in a case where the intermediate luminance value of a second target light-emitting unit among the plurality of light-emitting units is smaller than the intermediate luminance value of the second neighboring light-emitting unit neighboring the second target light-emitting unit, the second processing unit corrects by increasing the intermediate luminance value of a second target light-emitting unit according to a difference of the intermediate luminance value of a second target light-emitting unit and the intermediate luminance value of the second neighboring light-emitting unit.
