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, wherein the first processing unit increases an initial luminance value of a first target light-emitting unit among the plurality of light-emitting units that is greater than an initial luminance value of a first neighboring light-emitting unit neighboring the first target light-emitting unit, according to a difference of the initial luminance value of the first target light-emitting unit and the initial luminance value of the first neighboring light-emitting unit;

    a second processing unit configured to acquire correct luminance values of the plurality of light-emitting units by correcting the intermediate luminance values, wherein the second processing unit increases an intermediate luminance value of a second target light-emitting unit among the plurality of light-emitting units that is smaller than an intermediate luminance value of a second neighboring light-emitting unit neighboring the second target light-emitting unit, according to a difference of the intermediate luminance value of the second target light-emitting unit and the intermediate luminance value of the second neighboring light-emitting unit, the second target light-emitting unit being same or different from the first target light-emitting unit; 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.
