Abstract:
1. An image processing method, comprising: filtering noise of a first image and converting the first image to obtain a first luminance signal, wherein the first image is defined in a first color space; performing a color space converting process upon the first image according to the first luminance signal to obtain a second image, wherein the second image is defined in a second color space; storing and outputting the second image; filtering noise of the second image and converting the second image to obtain a second luminance signal; performing a linear computing upon the second image according to the first luminance signal and the second luminance signal to obtain a third image, wherein the third image is defined in the second color space; performing an error compensation upon the third image and the second image and outputting the third image; and performing the color space converting process according to the third image and the first luminance signal to obtain and output a fourth image, wherein the fourth image is defined in the first color space.
