发明名称 Image processing apparatus and method which compresses image data of each region using a selected encoding method
摘要 This invention has as its object to provide an image processing apparatus, which can obviate the need for image re-input, can effectively generate encoded data that falls within a set size, and can minimize deterioration of image quality. To this end, an image processing apparatus according to this invention includes a first discrimination unit for discriminating the type of image of each of a plurality of regions, which form image data input, a second discrimination unit for discriminating if the image data is inputted by a continuous scan of images, a selection unit for selecting an encoding method used in compression of each region on the basis of discrimination results of the first and second discrimination unit, a first compression unit for compressing image data of each region using the encoding method selected by the selection unit, and a second compression unit for compressing information that pertains to the type of image of each region.
