Abstract

The present invention proposes an image processing method and system, which obtains the pixel data of the target image and constructs a mapping function f regarding the target image in an isochromatic plane. 1 (x), according to the pixel data of the target image and the mapping function f 1 (x), so that the mapping function g(x) shown is automatically adjusted according to the pixel data of the target image, and after correction by the correction function, the final image is output, so that different images can maintain the color of the original image in the color gamut mapping and details.

Description

Technical field [0001] The present invention relates to the technical field of image processing, in particular to an image processing method and system. Background technique [0002] With the improvement of people's living standards, the pursuit of display effects of electronic products is getting higher and higher. In the prior art, when a color image is copied between different devices, since the color gamut of each device is different, it is necessary to perform a mapping transformation in order to minimize the color loss or distortion of the image during the copying process. In general, the evaluation criterion of the transformation mapping algorithm is as accurate as possible or as close as possible to the original color of the image. [0003] The general method of mapping from a small color gamut to a large color gamut is to expand linearly with fixed-point matching, but it is more complicated to transform from a large color gamut to a small color gamut; figure 1 Shown, incl...
