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.

An inspection apparatus obtains a correction parameter for correcting the positional shift between a previously read image and a master image, and corrects one of a currently read image or a master image using the correction parameter for the previously read image, before comparing between the currently read image and the master image to detect the positional shift in the currently read image.

An image inspection apparatus obtains a threshold value indicating an allowable range of offset differences between an output target inspection image and a pre-provided inspection image, and determines whether to inspect a read image obtained by reading an output target image formed on a recording sheet having a pre-provided image, using the threshold value.

An image output apparatus includes: an image forming unit that forms an image on a recording medium; a test-threshold acquiring unit that acquires a test threshold that is a pass-fail criterion for the image test for determining whether the test image data passes or fails the image test; a changing unit that changes a density detection mode of at least one of the image forming unit and the image reading apparatus on the basis of the test threshold; a density correcting unit that corrects density used in an image forming process performed by the image forming unit; and a reference-image-data acquiring unit that acquires the reference image data.

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.

An image-reading device is provided. The image-reading device comprises a photoelectric converting element reading a first image from a subject copy, a reference-white member functioning as a reference white used in a white-shading correction, reading means for reading a second image from a constant range on a surface of the reference-white member by using the photoelectric converting element, averaging means for dividing image data of the second image into a plurality of blocks in a sub-scanning direction so that each of the blocks includes a plurality of lines and obtaining average values of image data of the lines in the blocks respectively, peak-value determining means for obtaining a peak value of the average values, and white-shading correcting means for performing the white-shading correction to image data of the first image by using the peak value as white-shading data.
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 inspection apparatus, inspection system, inspection method, and inspection control program stored in a recording medium, each of which sets a reference point in a master image and a read image read from a printed image, which is to be used for detecting the positional shift between the read image and the master image, based on determination whether a pattern previously added to the printed image for detecting the positional shift is available or can be used to effectively detect the positional shift.

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.
