ABSTRACT:
An image processing apparatus includes: a document type automatic classification section which determines whether input image data is image data for a text document or not; a newspaper document classification section which determines whether the input image data is image data for a newspaper document or not; a segmentation process section which identifies a page-background region in the input image data; and a color correction section for, if the input image data is classified as the text document and but not the newspaper document and if a page-background removal process is to be performed to the input image data, performing a first page-background removal process to the image data, but if the input image data is classified as the text document and the newspaper document, not performing the first page-background removal process to the image data. This makes it possible to prevent deterioration of visual sharpness of the text in the document image printed on the newspaper.
