Abstract
An afterimage compensation device includes: an afterimage area detector to receive an input image, and detect an afterimage area including an afterimage in the input image; an afterimage area corrector to detect a false detection area, and generate a corrected afterimage area, the false detection area being a part of a general area that is not detected as the afterimage area and surrounded in a plurality of directions by the detected afterimage area; and a compensation data generator to adjust a luminance of the corrected afterimage area to generate compensation data.
Claims20
An afterimage compensation device comprising:
- an afterimage area detector configured to receive an input image, and detect an afterimage area comprising an afterimage in the input image;
- an afterimage area corrector configured to detect a false detection area, and generate a corrected afterimage area, the false detection area being a part of a general area that is not detected as the afterimage area and surrounded in a plurality of directions by the detected afterimage area;
- and
- a compensation data generator configured to adjust a luminance of the corrected afterimage area to generate compensation data.
An afterimage compensation device comprising:
- an afterimage area detector configured to receive an input image, and detect an afterimage area comprising an afterimage in the input image;
- an afterimage area corrector configured to correct an extended area extended from a boundary of the detected afterimage area by a preset pixel size as a corrected afterimage area;
- and
- a compensation data generator configured to adjust a luminance of the corrected afterimage area to generate compensation data,
- wherein the afterimage area corrector is configured to determine a pixel size of the extended area in a corresponding direction that is proportional based on a length of the detected afterimage area in the corresponding direction.
A display device comprising:
- an afterimage compensation device configured to detect an afterimage area from an input image, correct the detected afterimage area to generate a corrected afterimage area, and output compensation data applied to the corrected afterimage area;
- a timing controller configured to generate pixel data based on the compensation data;
- and
- a display panel configured to display an image based on the pixel data,
- wherein the afterimage compensation device comprises:
- an afterimage area detector configured to receive the input image, and detect the afterimage area comprising an afterimage in the input image;
- an afterimage area corrector configured to detect a false detection area, and generate the corrected afterimage area, the false detection area being in a part of a general area not detected as the afterimage area and surrounded in a plurality of directions by the detected afterimage area;
- and
- a compensation data generator configured to adjust a luminance of the corrected afterimage area to generate the compensation data.
