摘要
An image processing method includes: receiving specific data of an image component of input image for a specific color encoding channel wherein the specific data of the image component is formed by the image component's multiple raw values having identical image characteristics; spatially classifying pixel units within the input image into a plurality of blocks according to a specific block size; for each block, obtaining values of the image component of pixel units within each block to calculate the average value of the image component of the each block; generating interpolated values of the image component of an interpolated image according to values of the image component corresponding to the plurality of blocks; and, blending the interpolated values of the image component of the interpolated image with original/raw values of the image component of the input image to generate an output image having modified values of the image component.
