Abstract:
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.

Abstract:
An image forming apparatus includes a first density correction unit that corrects density correction characteristics in correcting density of print image data to be output by using a density correction patch formed in an image forming process; a second density correction unit that corrects the density correction characteristics by using a density correction patch printed on a recording sheet; an image inspection unit that compares an image density of inspection image data obtained by scanning a printed output image with an image density of the print image data to be output, thereby inspecting a magnitude of a density change in the printed output image; and a density control unit that selects one from the first and second density correction units according to the magnitude of the density change and causes the density correction characteristics to be corrected by the selected one from the first and second density correction units.
Abstract:
An image reading device includes an imaging device including a plurality of imaging elements, a color measuring unit that detects color of an object at a color measurement area, a calibration plate having a surface on which a plurality of color patches is formed, and a processor that causes the color measuring unit to read the plurality of color patches while changing a relative position between the plurality of color patches and the plurality of imaging elements to output color measurement results of the plurality of color patches, and generates a set of reference values for the plurality of color patches based on the color measurement results of the plurality of colors. The set of reference values are compared with the reading results of the plurality of color patches to generate a set of correction values for correcting the reading results of the plurality of color patches.

Abstract:
An image test apparatus includes a color-image-data acquiring unit that acquires color image data being data of an image to be formed with a color material; a master-image-data generating unit that converts the color image data depending on transparent image data being data of an image to be formed with a transparent color material, thereby generating master image data; and an image testing unit that tests, using the master image data, a test image data which is generated by optically reading a print image from a printed matter on which the print image based on the color image data and the transparent image data has been printed.
Abstract:
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.

Abstract:
An image processing apparatus implements appropriate image processing on image data stored in a storage unit of the image processing apparatus easily and efficiently, and distributes the image data to an external apparatus. An image format conversion unit implements image processing such as resolution conversion processing, filter processing, γ correction processing, and halftone processing on image data stored in an HDD serving as an image data storage unit so that the image data conform to conditions, such as image quality and format, specified by an external client apparatus. The image-processed image data are then distributed to the external client apparatus.
