For each region of interest (ROI) type of a number of ROI types, ROIs of the ROI type within a reference image are compared to corresponding ROIs within a test image corresponding to the reference image and printed by a printing device. For each ROI type, a feature vector characterizing image quality defects within the test image for the ROI type is generated based on results of the comparing for the ROI type. Whether print quality of the printing device has degraded below a specified acceptable print quality level can be assessed based on the feature vectors for the ROI types.

An image forming system may comprises an image forming unit, a sensor, and a controller. The controller configured to control the sensor based on measurement modes including a first measurement mode and a second measurement mode. A sampling number of an image by the sensor while the sensor moves in the direction orthogonal to the conveying direction in the first measurement mode is less than a sampling number of an image by the sensor while the sensor moves in the direction orthogonal to the conveying direction in the second measurement mode.

A sheet conveyance apparatus includes a sheet conveyor configured to convey a sheet, a guide configured to form a conveyance path through which the sheet is conveyed by the sheet conveyor, and a sensor disposed on a same side as the guide with respect to the conveyance path. The guide includes a retracted portion disposed over a first region in a sheet width direction perpendicular to a sheet conveyance direction, the retracted portion being retracted with respect to a second region of the guide in the sheet width direction so as not to come into contact with the sheet passing through the conveyance path, the first region including a detection region of the sensor in the sheet width direction, the second region being a sheet passing region of the sheet in the sheet width direction excluding the first region.

An image processing apparatus according to the present invention includes an image forming unit configured to form an image, a measuring unit configured to measure the formed image, a control unit configured to control execution of a single-color calibration to be performed to correct reproduction characteristics of a single-color formed by the image forming unit based on a measuring result of a single-color image formed with a single-color recording agent and execution of a multi-color calibration to be performed to correct reproduction characteristics of a multi-color image formed by the image forming unit based on a measuring result of a multi-color formed with a plurality of recording agents, and a selection unit configured to select whether to cause the control unit to perform the multi-color calibration after completing the single-color calibration or cause the control unit to perform any one of the single-color calibration and the multi-color calibration.

When a user overlaps a region set for a picture examination and a region set for a data examination, the user is not notified that a print image examination is not performed on the overlap region. A printing system reads a printout, generates a scan image, performs a first examination to examine the printout based on the scan image and a correct image, and performs a second examination to examine data acquired from the printout based on data acquired from the scan image and correct data, and in a case where at least a first region to be examined by the first examination and a second region to be examined by the second examination are set in the correct image and the first region and the second region include an overlap region, the printing system provides a notification of the overlap of the first region and the second region.

A conveying device can selectively execute discharge processes of a plurality of discharge procedures each having a different mode of discharge to a discharge tray. An image reading portion reads images on document sheets conveyed along a conveyance path and outputs data about read images. An image reading control method includes detecting a target image that satisfies a predetermined sorting condition associated with any one of the plurality of discharge procedures from the read images. The image reading control method further includes, in a case where the target image is detected, executing a discharge control that causes the conveying device to execute the discharge process of the discharge procedure corresponding to the target image.

There is provided an information processing apparatus configured to obtain criterion data, which is reference image data, by executing a adjustment parameter determining program, obtain evaluation data which is image data scanned by a scanner, generate a plurality of pieces of comparison data by adjusting the evaluating data using a plurality of adjustment parameters different from each other, respectively, associate each comparison data with an adjustment parameter used to generate the comparison data, and display the criterion data and the plurality of pieces of comparison data in a list. When a selecting operation of selecting one from the plurality of pieces of comparison data is performed, the information processing apparatus determines an adjustment parameter for the scanner based on the adjustment parameter associated with the selected comparison data.

An information processing apparatus includes a processor configured to: obtain plural images each including any of plural objects; and output report information that is information generated based on an analysis result regarding the plural objects in the plural images, and that is information for reporting according to which of two or more objects, among the plural objects, included in an image the image is to be corrected.

An image outputting device includes a scanning module, a storage module, an identification module, a calibration module and a printing module. The scanning module generates an image by scanning an object. The storage module stores the image. The identification module identifies a layout orientation and a text orientation of the image. The calibration module calibrates the layout orientation and the text orientation of the image according to a relation of an identification result of the identification module and a layout orientation of the printing medium. When the printing module prints the calibrated image on a printing surface of the printing medium and outputs the printing medium with the printing surface facing downwardly, the layout orientation of the printed image matches with the layout orientation of the printing medium, and the text orientation of the printed image is opposite to an medium outputting direction or arranged from proximal to distal.

An image processing apparatus for inspection of a sheet on which a code image obtained by encoding predetermined information is printed includes: a first acquisition unit which acquires positional information indicating a position and a size of the code image in the sheet; a second acquisition unit which acquires a plurality of read images obtained by a plurality of reading units reading different portions of the sheet, respectively, wherein the read images become an image indicating the entire sheet by being combined; a determination unit which determines whether any one of the read images includes the entire code image based on the positional information; and an extraction unit which extracts the predetermined information by, in a case where there is a read image including the entire code image, reading the code image in that read image.
