IPC: H04N1/40
Filed: 2000-10-30
Abstract: PROBLEM TO BE SOLVED: To provide an image processing apparatus that can easily convert multi-value image data with a low resolution into image data with a high resolution and a low gradation number. SOLUTION: In the conversion processing to an input image signal read by a scanner 5, an image processing section 34 quantizes the image signal at a fixed threshold in response to the image quality mode to apply gradation processing to the quantized signal.
