Abstract
Provided is an image processing device capable of specifying a character area included in an image even if a variable-density difference in an area included in the image other than the character area is large. A feature point specifying unit specifies corners of edges in a target image as feature points. An area obtaining unit obtains, based on a specified result of the feature point specifying unit, an area including a plurality of feature points aligned in a substantially straight line. A character area specifying unit specifies a character area in the target image based on the area obtained by the area obtaining unit.
