Abstract
A character-edge detecting unit detects a character edge area in an image. A character-inside-area detecting unit detects a character inside area in the image. A density-information detecting unit detects density information in the image. An image processing unit executes a predetermined image processing according to results of detecting the character edge area, the character inside area, and the density information. The image processing unit applies different image processings or different image processing parameters to the character inside area based on the density information.
