Abstract
An image processing system has a memory for storing programs, an unprocessed image and a processor for executing the programs in the memory. The image is a plurality of pixels arranged as a matrix, and each pixel has several color parameters. The image has at least one image region. One of the color parameters is adjusted according to an initial image adjusting value. Then, in one direction of up, down, left or right, the image adjusting value is successively changed by adding a fixed value, or multiplying by a fixed factor. Each successive pixel has its color parameter adjusted by adding the image adjusting value to it. Image adjustment proceeds in this way from the image region to an outer region along the predetermined direction.
