发明名称 Compression of photographic and halftone images
摘要 Disclosed is an image processing apparatus comprising an image compression conversion unit to quantize an image having attribute data for each pixel, wherein when a region has the attribute data of a photographic image, the image compression conversion unit quantizes the region by a BTC method, wherein when a region has the attribute data of other than the photographic image, and the region is a halftone region, the image compression conversion unit quantizes the region by the BTC method, and wherein when a region has the attribute data of other than the photographic image, and the region is a high resolution region, the image compression conversion unit generates a density pattern for the region to quantize the region according to the generated density pattern.
