Image formation apparatus and image processing apparatus

Abstract

The present invention is an image forming and processing device that can automatically select a color mode / monochrome mode even if a color and monochrome document are mixed in a document. Among them, the color characteristic extraction part extracts the color characteristic of the document from the image data from the scanning part, and the color / monochrome determination part judges whether the document should be output as a monochrome image or as a color image. The color / monochrome output color determination unit outputs the color image data from the scanning unit as monochrome image data when it is determined that it should be output as a monochrome image, and when it is determined that it should be output as a color image, The color image data from the scanner is output as color image data corresponding to predetermined color components.

Description

technical field [0001] The present invention relates to an image forming apparatus such as a digital color copier for forming a reproduced image such as a color image, and an image processing apparatus for processing a color image read from an original in the image forming apparatus. Background technique [0002] The originals to be reproduced are generally classified into the following three types according to the purpose of the reproduced image. [0003] (1) The original image is monochrome, and the image to be copied is also a monochrome original [0004] (2) The original image is in color, but the image to be copied is a monochrome original [0005] (3) The original image is in color, and the image to be copied is also a color original [0006] In existing color copiers, when generating the reproduced images of these three kinds of originals, the user who intends to generate the reproduced images performs one of the following two types of reproduction: [0007] (1) Co...

Problems solved by technology

[0018] For example, if the above-mentioned manuscript in which the image is written on a light-colored notebook with black ink (or pencil, etc.) is reproduced in color, since the background color that accounts for most of the original manuscript is a colored area, it will consume a lot of expensive paper. color material

[0019] In addition, when duplicating advertising sheets or brochures with a background color in color, a large amount of expensive color materials will also be consumed.
