An image inspection system includes: a hardware processor that controls image formation by an image former based on a read image generated by reading, by a reader, a medium on which a patch is formed, wherein the hardware processor causes the image former to form, on the medium, a patch corresponding to an image formed on a medium by the image former.

Image inspection system for print setting correction

An image forming apparatus forms a color image on a recording medium by superimposing images of colors formed by image forming units. The apparatus includes a processor that: acquires a read image by reading the recording medium on which the color image has been formed; forms a register patch outside a job image forming region of the recording medium; and corrects image forming positions of the image forming units based on the read image that includes the register patch. The register patch includes: a leading end patch and a rear end patch formed with a reference color material; and one or more measurement target color patches formed with measurement target color materials between the leading end patch and the rear end patch. The hardware processor corrects the image forming positions based on relative positions of the leading end patch, the rear end patch, and the measurement target color patches.

Image forming apparatus and storage medium

An image inspection apparatus includes a first reader and a second reader that acquire read images by respectively reading one side and the other side of a sheet having an image printed thereon, a first background material and a second background material provided at positions as the backgrounds of the sheet in reading by the first reader and the second reader respectively, and a hardware processor that acquires sheet outline information from the read images and measures misalignment of the image with respect to the sheet based on the acquired sheet outline information. The hardware processor acquires read images with the first background material and the second background material having different densities, and acquires sheet outline information of one read image by estimating the sheet outline information of the one read image based on sheet outline information of the other of the read images.

Image inspection apparatus and misalignment measurement method

An image inspection apparatus includes the following. A reader reads a sheet in which an image is printed, reads the sheet together with a background, and obtains a read image. A background member is provided in a position which is to be a background of the sheet when the sheet is read by the reader. A hardware processor extracts sheet outline information of the sheet from the read image and measures a misalignment of a position of the image with relation to the sheet based on the extracted sheet outline information. The hardware processor performs control based on a measured result of the misalignment of the position of the image. The hardware processor adjusts a degree of control performed based on the measured result of the misalignment of the position of the image according to a density difference between the sheet and the background member.

An image processing apparatus includes a beam corrector which corrects a gray level of each pixel in image data so as to reduce a density difference due to a misalignment in beam position of laser beams of a multibeam array. The beam corrector includes a calculator which detects an edge of an object between a pixel and adjacent pixels of the pixel in the image data and calculates an edge intensity of the edge. The calculator calculates a corrected gray level of the pixel from the calculated edge intensity and a correction value corresponding to a deviation in beam position of the laser beams emitted according to a gray level of the pixel.

Printed material processing device and non-transitory recording medium storing computer readable program

An image processing apparatus includes: an image processing unit configured to execute, in forming an image on both surfaces of a sheet, image processing including skew correction to deform the image in advance to offset distortion to be caused in the image to be formed on the sheet, wherein, the image processing unit receives specification of any of one side, two sides, and an external form of the sheet, as a reference position of the image processing for the image to be formed on the both surfaces of the sheet, and executes the image processing including the skew correction based on the specification.

Image processing apparatus and image processing method

An image processing apparatus includes: an image processing unit configured to execute image processing including skew correction that deforms an image so as to cancel distortion on the image; and a control unit configured to control the image processing on the image processing unit, wherein, in a case where a margin amount available for correcting the distortion is defined as a first correction margin amount and a margin amount used for correction other than skew correction is defined as a second correction margin amount, the control unit calculates a third correction margin amount obtained by subtracting the second correction margin amount from the first correction margin amount, and controls such that the image processing unit executes the image processing including the skew correction toward a first image and a second image such that the skew correction amount to be corrected falls within a range of the third correction margin amount.

The object of the present invention is to provide a disk array device, a failure path specifying method and a program thereof capable of specifying a physical interconnection path where failures occurred.

Disk array device, a failure path specifying method and a program thereof

An image processing device includes an image-modification processing unit and an adjustment unit. The image-modification processing unit executes first image-modification processing wherein pixels are inserted to or deleted from a subject image in a first direction or pixels in the subject image are shifted in the first direction and second image modification processing wherein pixels in the subject image are shifted in a second direction. The adjustment unit adjusts a position of a shift-border along which the pixels are shifted in the second image-modification processing on the basis of a position of each step in an image caused in the first image-modification processing.

An image forming method which is capable of preventing occurrence of moire and forming images having sufficient color saturation and a sufficient gloss is provided. The color toner image is formed in accordance with a color image signal obtained through screen processing using a screen pattern having a screen line count of 50 to 270 lpi on manuscript image data, and the clear toner image is formed in accordance with a clear image signal obtained through contone processing on the manuscript image data. The clear image signal is controlled so that, according to the amount of the color toner per unit area of the stacked toner image obtained by the color toner image being superimposed with the clear toner image, the less the amount of the color toner, the more the amount of the clear toner becomes.
