1. A method for denoising an image, comprising:
dividing one frame of to-be-processed image into a plurality of image areas;
for each image area, expanding an edge of the image area to obtain an expanded area; wherein the expanded area comprises the image area and an edge area, and the edge area comprises pixels in another image area adjacent to the image area; wherein contents displayed by the pixels in the adjacent another image area are different from and are related to contents displayed by pixels in the image area;
for each expanded area, performing denoising processing on the expanded area through a preset algorithm to obtain a denoised expanded area; wherein the denoised expanded area comprises a denoised image area and a denoised edge area; and
abandoning the denoised edge area in each denoised expanded area, and retaining and combining all the denoised image areas to form a denoised image.
