Abstract:
1. 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 the edge information based on a pixel statistical value of an area that is wider than an area of a specific layer; correcting difference information between a pixel statistical value of the area of the specific layer and the pixel statistical value of the area of a layer that is wider than the area of the specific layer using the post-correction edge information; correcting the pixel statistical value of the area of the specific layer using post-correction difference information and the pixel statistical value of the area that is wider than the area of the specific layer; and correcting the target pixel by repeating correction 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.
