Abstract

PURPOSE:To improve the sharpness of the image of a sentence part and the restoration of the image of a photograph part by executing respectively different image processings to an image signal part corresponding to a binary area discriminated by an area discriminating means and an image signal part corresponding to a multi-value area with an image data composing means and composing image data. CONSTITUTION:An image signal read by an original reading means M1 is discriminated to a binary area and a multi-value area by an area discriminating means M3. An image data composing means M2 to read this discriminated result, based on the image signal read from the original reading means M1, executes respectively different image processing to a part corresponding to the binary area and multi-value area and image data are composed. Thus, to the binary area to be able to be binarized, a binarization processing can be executed and to the multi-value area to be made multi-value larger than three, a multi-value processing can be executed.
