    摘要: An image processing apparatus includes an input device for inputting image data representing an image. A first discriminating device discriminates whether the image represented by the input image data is a first predetermined image, and a second discriminating device discriminates whether the image represented by the input image data is a second predetermined image different from the first predetermined image. An output device combines discrimination results of the first and second discriminating devices and outputs a discrimination signal. The first and second discriminating devices perform the discriminating operations in parallel.

    摘要: The color tone distributions of a plurality of types of specific originals are stored in advance in a ROM, and a first similarity between the color tone distributions corresponding to a predetermined discrimination criterion, and an input image signal is discriminated. A second similarity between the color tone distributions corresponding to a discrimination criterion which is changed based on the first similarity, and the input image signal is discriminated. Whether or not an original is similar to one of the plurality of types of specific originals is discriminated on the basis of the first and second similarities.

    摘要: A color image processing apparatus which judges a saturation of an input color image, and performs image processing in accordance with the saturation judgement result, includes an image input means in which a plurality of line sensors for generating color component signals on the basis of different spectral characteristics are parallelly arranged, and means for judging an achromatic area of the color component signals input by the image input means in accordance with a predetermined method. This arrangement performs saturation judgement when a printing operation using only black is performed for a black character or when it is judged whether an original document is a monochrome or color original document.

    摘要: A color image processing apparatus that prevents counterfeiting by detecting specific originals with high precision. Although general banknotes have graphic patterns drawn on uniform density portions, the tonality percepted by human eye is the mixture of the tonality of a graphic portion and the tonality of a uniform density portion. In consideration of the mixed tonality sensed by human eye, the apparatus smoothes a read image signal to generate mixed tonality for judgment, thus improves judgment precision. The total judgment of existence/absence of specific original is made by performing m judgments on m (m>n) judging conditions using the tonality data of pre-registered n (n: positive integer) specific originals.
