    摘要: An image processing apparatus is disclosed. The image processing apparatus stores image data read by a document reading section and image data received from an external device. An image data synthesizing unit synthesizes first image data read by the document reading section and second image data read by the document reading section or received from the external device. An image correcting unit generates image distinctive data of the first and second image data. A synthesized image distinctive data generating unit synthesizes the image distinctive data of the first and second image data by referring to an LUT (lookup table) selected by a synthesized image distinctive generating rule selecting unit. A predetermined process is applied the synthesized image data based on the synthesized image distinctive data.

    摘要: A spatial filter applies a modulation transfer function correction process so as to increase a number of bits of input image data. A high-resolution converter converts the image data into output image data having a density higher than a sampling density of the input image data. One of the spatial filter and the resolution converter processes the image data after the other of the spatial filter and the resolution converter has processed the image data A possibility of saturation of an output of the spatial filter is decreased, thereby decreasing generation of moiré in a saturation calculation.

    摘要: An image data correcting device eliminates a back projection image without eliminating an image corresponding to a low-intensity halftone image. An intensity difference detection part detects an intensity difference between first image data corresponding to a part of a predetermined small area and second image data corresponding to the remaining parts of the predetermined small area. A halftone detection part determining whether the first image data corresponds to a halftone image. An intensity change part changes an intensity of the first image data to a predetermined low intensity, when the intensity difference is equal to or smaller than a first predetermined value and the first image data does not correspond to the halftone image and the intensity of the first image data is equal to or smaller than a second predetermined value.
