Abstract:
An image processing apparatus determines the attribute of a pixel block, which is composed of a prescribed number of pixels extracted from image data, and the attribute of an area in which each pixel of the pixel block belongs. Then, based upon the determined attribute of the image block and the determined attribute of the area in which each pixel belongs, the apparatus subjects the image data to processing, pixel by pixel.
