The present invention is an image processing method comprising: calculating a pixel statistical value and edge information of pixels for each of areas of a multi-layer, the areas each containing a target pixel and having a successively decreased range; correcting difference information between a pixel statistical value of an area of a specific layer and a pixel statistical value of an area of a layer that is wider than the area of the specific layer using the edge information; correcting the pixel statistical value of the area of the specific layer using post-correction difference information, the pixel statistical value of the area that is wider than the area of the specific layer, and a pixel statistical value of an area that is wider than the areas of other layers; and correcting the target pixel by repeating correction and recorrection of the pixel statistical value of the area of the specific layer successively in each layer until the area reduces its range from the maximum range to the minimum range. |
