Abstract
An image processing method for scaling an image from an original resolution to a target resolution is provided. A pixel value Pof a target pixel point Nin the target resolution is theoretically composed of original pixel values P-Pof original pixel points N-Nin the original resolution, wherein K is a positive integer larger than 1. First, theoretical combination ratios R-Rcorresponding to the original pixel points N-Nare found. Then, the theoretical combination ratios R-Rare converted to corresponding weights W-W, wherein each of the corresponding weights W-Wis an integer between 1 and 2, n is an integer, and the sum of the corresponding weights W-Wis 2. The original pixel values P-Pare calculated with the corresponding weights W-Wusing a scaler, to generate the pixel value Pof the target pixel point Nand complete the image processing.
