Abstract
An afterimage detection device includes a downscaling unit that downscales an input image at a preset ratio, an image accumulation unit that receives at least one downscale image from the downscaling unit and accumulates the at least one downscale image, an afterimage detection unit that detects an afterimage from an accumulated downscale image obtained by the image accumulation unit and generates afterimage information, and a weight applying unit that receives the afterimage information, calculates a downscaling weight of a region of interest including the afterimage in the input image based on a time parameter, and provides the downscaling weight to the downscaling unit.
Claims20
An afterimage detection device comprising:
- a downscaling unit that downscales an input image at a preset ratio;
- an image accumulation unit that receives at least one downscale image from the downscaling unit and accumulates the at least one downscale image;
- an afterimage detection unit that detects an afterimage from an accumulated downscale image obtained by the image accumulation unit and generates afterimage information;
- and
- a weight applying unit that receives the afterimage information, calculates a downscaling weight of a region of interest including the afterimage in the input image based on a time parameter, and provides the downscaling weight to the downscaling unit.
An afterimage detection device comprising:
- a downscaling unit that downscales an input image at a preset ratio;
- an image accumulation unit that receives at least one downscale image from the downscaling unit and accumulates the at least one downscale image;
- an afterimage detection unit that detects an afterimage from an accumulated downscale image obtained by the image accumulation unit and generates afterimage information;
- and
- a weight applying unit that receives the afterimage information, calculates a luminance weight of a general region which does not include the afterimage in the input image based on a time parameter, and provides the luminance weight to the downscaling unit.
A display device comprising:
- an afterimage detection device that detects an afterimage of an input image and outputs afterimage data;
- a timing controller that generates compensation data based on the afterimage data;
- and
- a display panel that displays an image based on the compensation data,
- wherein the afterimage detection device comprises:
- a downscaling unit that downscales an input image at a preset ratio;
- an image accumulation unit that receives at least one downscale image from the downscaling unit and accumulates the at least one downscale image;
- an afterimage detection unit that detects an afterimage from an accumulated downscale image obtained by the image accumulation unit and generates afterimage information;
- and
- a weight applying unit that receives the afterimage information, calculates a downscaling weight of a region of interest including the afterimage in the input image based on a time parameter, and provides the downscaling weight to the downscaling unit.
