Claim One:
1. An image processing method comprising the steps of: dividing image data into a plurality of bands in such a manner as to have an overlap region between each pair of adjacent bands, wherein said plurality of bands include a first band and a second band that are adjacent; extracting regions, each with a different kind of attribute, from each of said plurality of bands; extracting a first region from one of said regions extracted from said first band and extracting a second region from one of said regions extracted from said second band, wherein said first region and said second region at least partially overlap with each other in said overlap region between said first band and said second band and have attributes different from each other; calculating a feature amount of extracted said first region; calculating a feature amount of extracted said second region; obtaining a decided attribute as either the attribute of said first region or the attribute of said second region for use in correction, based on said feature amount of said first region and said feature amount of said second region; and changing a designated attribute to said decided attribute if they are different, wherein said designated attribute is the attribute of said first region or the attribute of said second region, wherein the above steps are performed by a computer.
