摘要:
A digital image processing apparatus capable of high-quality reproduction in which a black isolation point does not lie scattered even for a manuscript document having a colored background. The digital image processing apparatus separates the image data from the document image into a character area and a picture area, and includes a character candidate area detecting circuit, a background area detecting circuit, an area judging circuit for judging an area satisfying at the same time the conditions of the character candidate area detecting circuit and the background area detecting circuit to be the character area and judging the area outside the character area to be the picture area, a character processing section for processing the image data in the character area, a picture processing section for processing the image data in the picture area, and an area process selecting section for selecting either one of the character processing section and the picture processing section on the basis of a judgment result of the area judging circuit.
