Abstract: An image processing apparatus (or method) includes a reception unit (or step) for receiving digital color image data through an interface from an external apparatus, and a discrimination unit (or step) for discriminating, from the received digital color image data, whether an image represented by the digital color image data is a specific image. A control unit (or step) controls printing using the color image data in accordance with a discriminated result by the discrimination unit.

Abstract: A discrimination device and method that generates a control signal used for controlling a color image processing apparatus that processes color image data in a first color space and generates color image data in a second color space different from the first space. The color image data in the first color space is input and then a discrimination is performed to determine whether an image represented by the input color image data includes a specific image. A control signal is generated based on the discrimination result.

Abstract: An image processing apparatus and method includes a scanner for scanning an original and generating electrical image data representing an image of the original to be processed, a processor for processing the electrical image data supplied by the scanner, and a device for determining whether the original represented by the electrical image data contains a specified image based on the electrical image data supplied by the scanner. The scanner scans the original a plurality of times and the device performs its determination operation on the same original a plurality of times, once for each scanning operation.

Abstract: A device that controls a color image processing apparatus receives color component signals representing an original, and extracts a pattern having a predetermined color from the original on the basis of the color component signals. The device determines whether the pattern includes a predetermined image registered in advance, and generates a control signal for controlling an image processing of the original on the basis of the determination result.

Abstract: An image processing apparatus for processing an input image and recording the image on a recording medium, and particularly a color copying apparatus which permits color copying of an original, and makes it possible to discriminate a specific original for the sake of prevention of forgery of a banknote, a negotiable instrument, or the like. The specific original is provided with copying processing which is different from that provided for an ordinary original.

Abstract: A color image reading apparatus has a reading unit for color-separating and reading a color image, an operating unit for obtaining an average value of each of a plurality of color-component signals output from the reading unit, and a transforming unit for transforming the plurality of color-component signals from the reading unit into a plurality of color-density signals on the basis of the average values of the plurality of color-component signals obtained by the operating unit.
