An image processing apparatus extracts an image area corresponding to a margin area of a chart for evaluation from a scanned image obtained by scanning a printed material on which the chart is printed. The image processing apparatus evaluates the printed material based on, in a case when a printing medium used for the printing is determined to be a printing medium having a specific characteristic based on the image area corresponding to the margin area, the scanned image from which influence based on the specific characteristic is decreased.

An image forming apparatus comprises an image forming unit; a sensor that measures a measurement image; and a controller. The controller controls the image forming condition based on a measurement result of measuring a first measurement image; acquires information having a correlation to density variation of images to be formed by the image forming unit; controls the image forming condition based on the information; determines a first value regarding a density of an image to be formed, based on a measurement result of measuring a second measurement image; determines a second value regarding a density of the image to be formed by the image forming unit, based on the information; and controls a timing at which the image forming unit next forms the first measurement image, based on the first value and the second value.

A reading device includes a carriage movable in a sub-scanning direction, an optical sensor mounted on the carriage, the optical sensor being configured to scan an object placed on a contact glass, a reference scale used as a reference when a dimension of the object is computed based on an image obtained as the optical sensor scans the object, a flat gauge to be scanned by the optical sensor to calculate a corrective value used to correct the image obtained by the optical sensor, and circuitry to calculate the corrective value based on a scanned image including the reference scale and the flat gauge obtained by the optical sensor, and correct, based on the corrective value, a measurement image including an image of the object and an image of the reference scale obtained by the optical sensor and compute the dimension of the object based on the corrected measurement image.

A lighting device (23) irradiates a web under conveyance with light. The lighting device includes a light source (43), and an irradiation port (61) configured to open linearly in a widthwise direction of the web at an end portion facing the web. The irradiation port (61) is formed between first and second parallel portions (62b, 63b) where a first plate member (62) and a second plate member (63) parallelly face each other. The web under conveyance is irradiated with linear light. It is possible to provide a lighting device capable of irradiating only an inspection region of a sheet or a web with light.

Textile printing wherein the printing comprises: acquire, by a controller, a print job comprising an image and a set of print parameters; position a textile in a printing zone; acquire a calibration image of the textile and transferring the calibration image to the controller; determine, by the controller, a set of calibrated print parameters based on the calibration image and the set of print parameters; and print the image on the textile using the set of calibrated print parameters.

A method for reducing image burn-in artifacts in an electrophotographic printing system, includes receiving a print job including image data for a set of pages to be printed. The pages are analyzed to determine that the image data for a sequence of pages in the print job are similar. The similar pages are printed using a pattern of lateral translations wherein the image data is laterally translated such that it is printed at a different lateral position on the printed page. The similar pages can also be printed using a pattern of page orientations including a first page orientation and a second page orientation, wherein the image data for the second page orientation is rotated 180 degrees relative to the image data for the first page orientation.

An information processing apparatus is configured to communicate with an image forming apparatus. The image forming apparatus includes a document feeder configured to convey, in order to read an original on an original tray, the original on the tray. The image forming apparatus is configured to form an image on a sheet based on a result of reading the original. The information processing apparatus includes an acquisition unit configured to acquire user instruction information about types of calibration selected from among a plurality of types of calibration for adjusting a quality of an image to be formed by the image forming apparatus; and a controller configured to determine test charts to be created by the image forming apparatus based on the user instruction information; receive an execution instruction that instructs to create the test charts in succession.

An image inspection apparatus includes a processor configured to acquire printing data that is data as a base of an image to be printed, acquire read data that is data obtained by reading the image printed on a paper sheet, perform correction of a blur caused by floating of the paper sheet occurring in the reading of the image, on the read data, and inspect the image by comparing the printing data with the read data after the correction.

There are provided an image processing device and an image processing method capable of efficiently specifying an abnormal sound in case of the occurrence of malfunction that is an important element to clarify the cause of the malfunction. The image processing device includes acquisition means, playing means, changing means, and determination means. The acquisition means acquires a plurality of kinds of sound data indicating sounds different from each other. The playing means plays one kind of sound data from the sound data. The changing means changes the one sound data to another kind of sound data. The determination means determines one kind of sound data from the sound data.
