Method and apparatus for performing correction processing on grayscale of a pixel in an image

An image processing apparatus, comprising a receiver, a display panel, a memory and a processor, wherein:

• the receiver is configured to receive a signal for an image to be displayed, wherein the image includes pixels;
• the memory is configured to store a computer readable program and a pre-created correction data table containing a pixel position, a marker and correction data;
• the processor executing the computer readable program is configured to perform correction processing on grayscale of each of the pixels in the image to be displayed according to a pixel position of each of the pixels within an active area of the display panel and the pre-created correction data table;
• wherein when the pixel position of a pixel belongs to a edge portion, the correction data corresponding to the pixel are correction data integrated from displaying correction data and edge correction data;
• when the position of the pixel does not belong to the edge portion, the correction data corresponding to the pixel are the displaying correction data;
• and
• the display panel is configured to display the image according to the processed grayscale of each of the pixels.

A display device, comprising an image processing apparatus, wherein the image processing apparatus comprises:

• a receiving device configured to receive a signal for an image to be displayed;
• a correction processing device configured, according to a pixel position of each of pixels within the active area of a display panel and a pre-created correction data table containing a pixel position, a marker and correction data, to perform correction processing on grayscale of each of the pixels in the image to be displayed;
• wherein when the pixel position of a pixel belongs to a edge portion, the correction data corresponding to the pixel are correction data integrated from displaying correction data and edge correction data;
• when the position of the pixel does not belong to the edge portion, the correction data corresponding to the pixel are the displaying correction data;
• and
• a displaying device configured to display the image according to the processed grayscale of each of the pixels.
