Abstract: Because all real color images contain noise in different degree and the high dynamic range of some real color images with dark shadows and bright light sources exceeds the range of most electronic capturing devices and human eyes scnscmg,real color images should be enhance and denoised at the same time. Based on the analysis of noise in H,S,V channel and a new illumination-reflectance model described by stationary wavclct transform(SWT)，a new method which can enhance and denoise real color images simultaneous was put forward. Experiments show that the color images are enhanced obviously and the noise is efficiently restrained at one time.
