Abstract
The present disclosure discloses a display device for improving visibility of an image and a visibility improvement method of an image therefor, and the display device implements global compensation and local compensation adaptively to content displayed in the image, thereby improving the visibility of the image.
Claims17
A display device, comprising:
- processing circuitry;
- and
- a memory coupled to the processing circuitry, wherein the processing circuitry is configured to:
- obtain input frame data corresponding to an image;
- classify content represented in the image as at least one first class of a plurality of classes;
- obtain image brightness level information of the input frame data;
- obtain an illuminance signal for the image;
- generate global compensation information based on the input frame data, the at least one first class, the image brightness level information, and the illuminance signal;
- identify a plurality of unit areas of the image;
- generate local compensation information for each unit area of the plurality of unit areas;
- generate output frame data based on blending the global compensation information and the local compensation information;
- and
- output the generated output frame data to a display,
- wherein the processing circuitry is further configured to:
- generate visibility reduction modeling information for compensation of a preset high luminance area and a preset low luminance area of the global compensation information;
- and
- output the visibility reduction modeling information.
