An image processing apparatus determines an attribute of a block image based on the attribute of the block image determined based on a color distribution characteristic amount of the block image and the attribute of the block image determined based on an edge characteristic amount of the block image.

Image processing apparatus, method, and storage medium for determining attributes

Image data is divided into blocks and a histogram of a color appearing in a target block is formed. A target color region is decided as significant, if the area of that region is larger than a threshold, or if that area is smaller than the threshold and if that region is located at a boundary of the target block and attribute information for the pixel at the boundary in that region indicates a preset attribute. If that region is not decided as significant, to integrate that region to a region of another color which contacts that region, the color of the pixel in that region is substituted by the other color. If that region is decided as significant and if the chrominance difference between that region and the region decided as significant in another block which contacts the target block is smaller than another threshold, these regions are integrated.
