Claim One:
1. A digital image processing enhancing system with denoising function, characterized in that, the system includes five modules: an input module, an image decomposing module, an illumination image processing module, a reflection image processing module, a composing and outputting module, wherein: the input module collects a digital image as a system input, a obtained digital image is input into the image decomposing module, the image decomposing module decomposes the input image into an illumination image L and a reflection image R, which are input into the illumination image processing module and the reflection image processing module respectively, the illumination image processing module performs a non-linear correction on the illumination image L of the input image and outputs a corrected illumination image L′, the reflection image processing module performs a denoising and filtering process on pixels corresponding to excessive dark regions in the reflection image R, and outputs a denoised reflection image R′, wherein the excessive dark regions of the input image can be determined by an information of the illumination image, then the composing and outputting unit re-composes the L′ and R′ output from the former two modules in an output image and outputs the output image to an output device.
