    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: 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.

    摘要: An image processing apparatus which processes image data either in a character image reading mode or a character/photo mixed-image reading mode. The apparatus includes an MTF filter that emphasizes the image data, a smoothing filter that smooths the image data, a memory that stores white data, a mesh-screen image judging device that judges whether the image data is a mesh-screen image in the character image reading mode and the character/photo mixed-image reading mode, and an isolated-pixel judging device that judges whether the image data is an isolated-pixel. A first selection device selects an output of the MTF filter when the isolated-pixel judging device judges the image data to be a non-isolated-pixel and selects the white data when the isolated-pixel judging device judges the image data to be an isolated-pixel, when the mesh-screen image judging device judges the image data to be a non-mesh-screen image. A second selection device selects an output of the first selection device when the mesh-screen image judging device judges the image data to be a non-mesh-screen image and selects an output of the smoothing filter when the mesh-screen image judging device judges said image data to be a mesh-screen image.

    摘要: An image checking device checks a printed image printed out on a printing medium. The image checking device includes a data acquiring unit that acquires checking-image data, original reference image data input to an image forming device, and, from an attribute-information storage unit of the image forming device, attribute information about a printing medium; a correction-parameter storage unit that stores therein a correction parameter corresponding to the attribute information; an image generating unit that reads, from the correction-parameter storage unit, a correction parameter corresponding to the attribute information, corrects the original reference image data by using the correction parameter, and generates corrected reference image data; and an image checking unit that compares the checking-image data with the corrected reference image data by using a pre-set value to determine the degree of matching between the checking-image data and the corrected reference image data, thereby performing image checking on the printed image.
