IMAGE PROCESSOR AND PROCESSING METHOD

摘要

PROBLEM TO BE SOLVED: To suppress the size of an input image contained in an intermediate code buffer as much as possible when an intermediate coding system is employed and to prevent the image quality from lowering even in the case of irreversible compression. SOLUTION: If an input image has a resolution lower than the output resolution at the time of image data processing, an image processor 4 stores input image data as it is, in an intermediate code buffer 41-5 and generates an output image from the stored input image at the end of a page based on the information of enlarging or reducing rate. It is composited with other object before being delivered to an output unit.
