Abstract:
1. An image processing apparatus comprising: image input means for inputting a multi-valued document image; binary image generation means for generating binary image data from the inputted multi-valued document image inputted by said image input means; layout analysis means for dividing the inputted multi-valued document image into a plurality of partial images based on the binary image data generated by said binary image generation means, and generating layout analysis data which includes information of an image attribute of each partial image and information of a layout of each partial image; storage-level setting means for setting a storage level of the document image, the set storage level being selected from a plurality of predetermined storage levels based on an operation of a user; and storage means for selectively compressing and storing, as image comprehension data for the inputted multi-valued document image, a combination of (i) partial images having a text attribute, (ii) partial images having a second attribute different from the text attribute, and (iii) the entire inputted multi-valued document image, based on the set storage level, without storing the uncompressed inputted multi-valued document image, wherein said storage means comprises:
