ABSTRACT:
A background color of a document is detected based on image data of a colormetric system in which brightness and color components are separated. A color plane is divided into color areas, and the number of elements of image data belonging to each color area is counted. The number of elements of image data belonging to each area of a multiple area constituted of mutually adjacent color areas is then counted. A color area in which the number of elements of image data exceeds a first threshold is extracted and given a positive evaluation. A multiple area in which the number of elements of image data exceeds a second threshold is extracted and a positive evaluation is given to each color area in the multiple area. A color area receiving a positive evaluation both individually and as part of a multiple area is specified as a background color.
