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.

摘要： An image processing apparatus is provided that restrains image quality deterioration of image data read with a resolution in a sub-scanning direction set lower than a resolution in a main scanning direction from a document containing text, halftone photographs, line drawings, photographs, etc. An image processing apparatus performs the tone reproduction processing by applying error diffusion processing to the image data that has undergone processing of making the resolution in the sub-scanning direction equal to the resolution in the main scanning direction when the resolution in the sub-scanning direction is lower than the resolution in the main scanning direction and applying dither processing to the image data in other case. When the resolution in the sub-scanning direction is lower than the resolution in the main scanning direction, the halftone processing is applied to the entire image data that sharpness and smoothing processing has been performed.

摘要： In an image processing apparatus, a color/monochrome determination section determines whether color image data is image data indicative of a color document or image data indicative of a monochrome document, regardless of which color setting is selected to output image data, and a control section stores a determination result and the color image data in a storage device so that they are correlated with each other. Upon receiving a change instruction to change the color setting, the control section generates output image data, following a color setting that is changed according to the change instruction, on the basis of the determination result and the color image data each stored in the storage device. As a result, even if the color setting is desired to be changed, it is possible to carry out output processing without reading the document from an image reading apparatus again.

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： In a copier, a specific pattern being hardly recognizable by human eyes but recognizable by a recognizing means is added onto a color image to be printed on a recording medium in order to clearly indicate that the printed image is a copy image. RGB-color image data is converted by a post processing portion of an image processing unit into YMCK color image data. An additional color forming unit calculates color data YaMaCaKa of a specific pattern received from a specific pattern generating unit based on the RGB-color image data. A combining unit generates output Y′M′C′K′-color image data including the specific pattern color image data by combining YMCK color data with the specific pattern data of YaMaCaKa. An image output unit adds the specific pattern on the color image according to the Y′M′C′K′ color image data.

摘要： A display control device controls an image display device capable of displaying a preview of an output image that is to be subjected to an output process, before the output image is subjected to the output process. The display control device refers to a storage section in which specific information specifying an image process which a user cannot recognize from a previewed output image is stored, and selects an image process specified by the specific information out of image processes to be carried out on the output image. Further, the display control device causes the image display device to display a setting confirmation image showing a content of the selected image process. This allows a user to correctly understand the content of an image process to be carried out on the output image and the image quality of the output image subjected to the output process.
