Abstract
A method for processing image noise in a compression process and a circuit system thereof are provided. The circuit system receives an image that is compressed in a specific compression format, and obtains pixel values after the image is decompressed. Differences of pixel values between pixels adjacent to each other can be calculated. A specific area of the image can be divided into multiple sections. A maximum pixel value and a minimum pixel value for each area are used to obtain a regional maximum difference. The regional maximum difference is used to determine whether or not to perform an image-denoising process on the areas such as a flat area or a high-frequency area. Differences among the adjacent pixels can be adjusted according to a weighted average brightness of the adjacent pixels. The image-denoising process is performed on the areas, and an image with reduced noise is finally outputted.
