An image correction apparatus reduces an input image, for each area, at a reduction ratio corresponding to the area, generates a reduced luminance image, and extracts a low-frequency component image from the reduced luminance image. The image correction apparatus enlarges the extracted low-frequency component image, for each area, at an enlargement ratio corresponding to the area, generates correction data according to a size of the input image, and corrects the input image according to the correction data. |
