Abstract
Regarding a color difference between a color of an original image on a pixel other than a connection pixel set in a rectangular area that is an inside area of a rectangle circumscribed to the connection pixel set and a color of the original image on a pixel in the connection pixel set, the binary image generating unit (a) identifies whether the connection pixel set is a character or non character by comparing a value of an index that indicates unevenness of the color differences with a color difference threshold value, (b) identifies whether a size of the rectangular area is small or large on the basis of a threshold value, and (c) sets the color difference threshold value as a value if the size of the rectangular area is small and as another different value if the size of the rectangular area is large.
