Abstract

An image processing apparatus in which image data is input, a generator generates area information and a processor processes the image data in accordance with the area information. The generator includes a first generator for generating the area information by using area data for each pixel having a predetermined size stored in a memory, and a second generator for generating the area information by use of a central processing unit (CPU) without using the area data stored in memory. A selector selects one of the area information generated by the first and second generators so that the processor can process the image data in accordance with one of the area information generated by the first and second generators.
