The present invention discloses a method and a device for color correction for solving a problem of low color correction processing speed for images input into a computer in the prior art. A main technical solution includes: an input image is divided into no less than one image blocks; various color component values of all pixels in each image block are compared with each other, an image block with the same color component values of all pixels being regarded as a simple block, and an image block with different color component values being regarded as a complex block; and a process of color correction is performed on one pixel of the simple block, then the color correction processing result is copied to other pixels of the simple block. With the technical solution, an object of increasing processing speed can be achieved by performing simplified processing directly toward certain image parts with special features, and the color correction processing speed can be increased without general influence on the present color correction effect. |
