ABSTRACT:
An image processing device detects a candidate area of a background color in a chromaticity plane with respect to an original scanned document. A background color area is determined based on the candidate area of the detected background color. Boundary lines extending from the determined background color area to an achromatic-color area are generated. The background color area and an area surrounded by the background color area and the boundary lines are set as a mask, and the background color of the original document is deleted.
