Abstract: Embodiments of this application disclose an image denoising system and an image denoising method. In the image denoising system disclosed in the embodiments of this application, an image signal obtaining unit obtains and outputs an image signal. A processing unit performs preprocessing on the image signal to obtain image data, performs Sobel operator calculation on a current pixel in the image data to obtain a Sobel operator of the current pixel, corrects the Sobel operator of the current pixel, and determines, according to the corrected Sobel operator, whether denoising processing needs to be performed on the current pixel. When the denoising processing needs to be performed on the current pixel, the processing unit calculates an average pixel value of pixels around the current pixel, and performs denoising processing on the current pixel by using the average pixel value and the corrected Sobel operator.
