The present invention relates to an image processing apparatus, an image processing method, and an image reading apparatus for processing image signals including specific originals such as bills and marketable securities.
In general, in an image forming apparatus such as a digital copying machine that handles image information, reading means such as a scanner reads an original. Image information read and digitized is multi-valued, processed according to a purpose, and outputted from an output apparatus such as a laser printer.
An image forming apparatus such as a color multifunction peripheral that forms a color image has a specific image discriminating function. The specific image discriminating function discriminates whether a read original is a specific original such as a bill or a marketable security. When an input image is the specific original, an output apparatus prohibits copying of the input image by, for example, entirely painting the image in black (JP-A-2005-184497).
The accompanying drawings, which are incorporated in and constitute a part of the specification, illustrate embodiments of the invention, and together with the general description given above and the detailed description of the embodiments given below, serve to explain the principles of the invention.
FIG. 1 is a diagram showing an image forming apparatus;
FIG. 2 is a block diagram showing a functional configuration example of an image forming unit;
An image processing apparatus, an image processing method, and an image reading apparatus according to an embodiment of the present invention are explained with reference to the accompanying drawings.
FIG. 1 is a diagram showing a configuration example of a tandem image forming apparatus 1 mounted with an image processing apparatus. As shown in FIG. 1, the image forming apparatus 1 includes a scanner unit 2, an image forming unit 3, and a paper feeding unit 4.
The scanner unit 2 irradiates light on an original set on an original stand, guides reflected light from the original to a light-receiving element via plural optical members, photoelectrically converts the reflected light, and supplies an image signal to the image forming unit 3.
