Abstract

An image processing apparatus includes a document type automatic discrimination section that, based upon input image data read from a document, automatically discriminates a document type of the document. The document type automatic discrimination section, based upon plural types of parameters (quantity of halftone pixels, quantity of photographic-picture pixels, and quantity of high density pixels) obtained from plural types of characteristics (maximum density difference, total density busyness) extracted from the input image data and which parameters are used for discriminating a document type. A specific inkjet printed image whose output image data would not reach a standard level, if a process for a halftone reproduction region or a process for a continuous tone region were to be carried out on the input image data. This can improve the accuracy of document discrimination and the image quality of reproduced image.
