摘要： Unevenness in density (line noise) resulting from color misregistration among RGB components in a halftone region or a line screen region is suppressed. With respect to a document that is discriminated as a printed photo document or a text/printed photo document that includes black halftones by a document type discrimination section, or to a region segmented into a black halftone region by a segmentation section, a non-uniform image suppressing operation mode is executed. In the non-uniform image suppressing operation mode, a black generation and under color removal section does not carry out a black generation and under color removal process on a pixel in which a minimum value of the image data of the plurality of color components is at least equal to or less than a predetermined threshold.

摘要： A document matching process section calculates feature points (e.g., the centroid) on the basis of an inputted document image, then selects a plurality of feature points from among the calculated feature points, and then calculates a hash value on the basis of the selected feature points. Then, on the basis of the calculated features, the document matching process section determines whether the document image is similar to a preliminary reference format (reference image). When it is determined as being similar, the document matching process section determines whether write-in is present in the document image, and then outputs a determination signal (a determination result indicating the presence or absence of write-in). In the determination of similarity of the document image, permission or non-permission for processing such as copying is determined more accurately than in the prior art.

摘要： The image processing apparatus executes a zoom process to an image data depending on a received zoom level, selects a dither matrix from a plurality of dither matrices each having a different resolution. The image processing apparatus selects a dither matrix that has a higher resolution in a case that the received zoom level is equal or less than a first zoom level to reduce the image data. Furthermore, the image processing apparatus selects a dither matrix that has a lower resolution in a case that the received zoom level is equal or more than a second zoom level to enlarge the image data.

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.
