Abstract

The invention provides an image compensation method suitable to a display. First, an image processing circuit obtains pixel data related to a current pixel, a first and a second adjacent pixels from an image frame. The first and the second adjacent pixels are respectively located at two opposite sides of the current pixel. Then, the image processing circuit determines whether a color block edge exists between the current pixel, the first adjacent pixel and the second adjacent pixel according to the pixel data related to the current pixel, the first adjacent pixel and the second adjacent pixel.The image processing circuit performs first color edge compensation on the pixel data related to the current pixel when determining that the color block edge exists between the current pixel and thefirst adjacent pixel and no color block edge exists between the current pixel and the second adjacent pixel. An image processing circuit is further provided.

Description

technical field [0001] The invention relates to an image processing technology, in particular to an image compensation method and an image processing circuit. Background technique [0002] In a display panel in which the ratio of light emitted by subpixels (Subpixels) is controlled to form an image through color mixing, the arrangement (Arrangement) of subpixels of each pixel has a certain degree of non-uniformity. For example, whether it is true color (truecolor) sub-pixel arrangement or sub-pixel rendering (Subpixel Rendering, SPR) sub-pixel arrangement, these arrangements all have a certain degree of non-uniformity. Due to the non-uniform arrangement of sub-pixels, color fringing may occur on the edges of objects in the image frame. The color fringing phenomenon comes from the fact that each edge of a pixel does not have three primary color sub-pixels, so the edge of a color block (object) after human visual integration may appear in an unexpected color. That is, the us...
