摘要： As the color conversion process for image data of an RGB signal, a color correction section 26 performs a color correction process, and a black generation and under color removal section 27 performs a black generation and under color removal process. In the color conversion process, the color correction section 26 and the black generation and under color removal section 27 are supplied with a halftone frequency recognized by a halftone frequency recognition section 23. The color correction section 26 and the black generation and under color removal section 27 change the process based upon the halftone frequency. As a result, an image processing apparatus is realized in which improved image quality can be produced by an optimum image process that is performed on an image containing a halftone area depending upon the halftone frequency of the halftone area so that image quality is improved.

摘要： 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.

摘要： A two color process section included in the image processing apparatus includes a luminance and chroma calculation section, an image-data determination section, and an output-color generation section. The luminance and chroma calculation section calculates a luminance value and a chroma value based on input image data. The image-data determination section determines the input image data, the chroma value of which is equal to or greater than a predetermined threshold, as first input image data constituting a chromatic color in a two-color image and determines the input image data, the chroma value of which is less than the threshold, as second input image data constituting an achromatic color in the two-color image. The output-color generation section generates image data of CMY from the first input image data based on the chroma value and the luminance value and generates image data of CMY from the second input image data based on the luminance value.

摘要： A segmentation process section classifies signals of pixels in input image data into respective signals of a black text/low density area, a black text/high density area, a color text area, and an area other than a text area. A black generation and under color removal section performs an under color removal process with respect to the signal of the black text/low density area so that an amount of UCR is a middle value (C, M, Y) of signals indicative of color component density levels. Consequently, it is possible to prevent color fringing and a white spot at a time when chromatic aberration occurs in the input image data.
