Abstract: The inspection apparatus performs first image processing on image data used in printing the image, and stores image data for which the first image processing has been performed as a reference image. The inspection apparatus determines whether a first reference image corresponding to a reference image that can be used in a job to be inspected is stored, and if it is determined that the corresponding first reference image is stored, performs second image processing on the first reference image to convert the first reference image into a second reference image corresponding to the job. The inspection apparatus obtains a scanned image by reading an image of paper on which printing has been performed according to the job and performs processing for matching the obtained scanned image and the second reference image.

Abstract: The present invention provides an inspection apparatus that inspects an image formed on a recording medium by a printing apparatus. The inspection apparatus stores, as a reference image, image data used to form an image on the recording medium, obtains target image data to be inspected, by reading an image to be inspected formed on the recording medium. The inspection apparatus applies noise components to the reference image, aligns the reference image to which the noise components have been applied with the target image data, and performs collation processing between the reference image and the target image data that have been aligned.

Abstract: At the time of printing a color page image in monochrome, multi-dimensional color component values of each object included in the color page image are converted into a gray value. Then, in the processing to widen a difference between a first gray value and a second gray value, in a case where a color represented by the first color component value and a color represented by the second color component value do not belong to the same color group, the difference between the first gray value and the second gray value is made larger than that in a case where both the colors belong to the same color group.

Abstract: An image forming apparatus includes an image forming device that forms an image on a sheet and an image reading device that conveys a document placed on a stacking portion and reads an image on the document. The image forming device outputs first and second output materials in succession. First output material constitutes a first type of sheet having a predetermined pattern image, and the second output material constitutes a second type of sheet having the predetermined pattern image. The image reading device conveys the first and second output materials in succession from the stacking portion and reads a first image and a second image. A first parameter to cause image formation using the sheet of the first type is acquired based on the first image and a second parameter to cause image formation using the sheet of the second type is acquired based on the second image.

Abstract: To make it unnecessary to repeat the same work in a case where a destination color is set for each of a plurality of adjustment-target colors within a printing-target image. A plurality of adjustment-target colors is set at a time for a printing-target image, a patch in a color having a desired tint is selected from among each similar color patch group for each adjustment-target color, and a destination color is determined, which is a conversion destination for each adjustment-target color.
