IMAGE PROCESSING APPARATUS AND IMAGE PROCESSING METHOD

According to this invention, image processes are classified into a plurality of categories, and the result of processes belonging to each category is written in an intermediate buffer prepared for the category. The order of categories is determined in advance, and an output from a process of a preceding category serves as an input to a process of a succeeding category. The preceding category includes image processes such as automatic correction requiring no quick response. The succeeding category includes image processes such as manual correction requiring a quick response.
