In an example, an image processing system may include an identification engine, a map engine, and a control engine. In that example, the identification engine may identify a color mapping resource in response to a classification identifier corresponding to image data, the map engine may map the image data with the color mapping resource having color space clause corresponding to the classification identifier, and the control engine may generate control data for operating a print apparatus to print based on the color mapping resource.

The invention provides an image-forming apparatus that includes a printer that performs printing, and a controller that determines, on a basis of settings related to a print job, whether to execute the print job as a print job related to test printing or execute the print job as a normal print job, and causes the printer to perform printing, in which the settings related to the print job include a plurality of items, and one or more combinations of a setting of another item with respect to a setting of one item are set as recommended settings, and, when the print job includes a setting of the another item other than the recommended settings with respect to the setting of the one item, the controller determines that the print job is a print job related to test printing.

An advertisement system includes a distribution member computer that causes a printer to print the test image data received from a posting server and transmits read data obtained by reading an image of a printed matter obtained by printing test image data by the printer to a posting server, and the posting server including an evaluation unit that evaluates printing quality of the printed matter based on the read data and a decision unit that determines whether to distribute the advertisement data to the distribution member computer based on an evaluation result by the evaluation unit.

Pixel blocks of a user-generated print job raster page are clustered into raster color clusters, and pixel blocks of a corresponding scanned page are clustered into scanned color clusters. For each raster color cluster, if a color difference between the cluster and a corresponding scanned color cluster is greater than a threshold, color fading of the cluster is determined from simulated depletion of each colorant of a printing device, and a likely depleted colorant is determined based on the corresponding scanned color cluster and the determined color fading. A most likely depleted colorant is determined from the likely depleted colorant predicted for each raster color cluster for which the determined color difference is greater than the threshold.

A mobile terminal includes a memory, and a processor coupled to the memory, wherein the processor executes a process comprising acquiring a frame with taking a photograph, acquiring document image data of a document from the frame, detecting shine on the document image data, determining whether the shine is equal to or smaller than a shine baseline, and acquiring a frame with retaking a photograph when the shine is neither equal to nor smaller than the shine baseline.

According to an embodiment, an image forming apparatus, comprises a document feeder to feed a document page by page, a scanner to scan the document fed by the document feeder and generate image data of the document, a printing apparatus to print images on recording media. An interface is configured to receive print settings and a test printing command. A controller is configured to control the document feeder to feed pages of the document according to the print settings when the test printing command is received, acquire image data of the pages of the document fed by the document feeder, and control the printing apparatus to print images in a test printing. The images in the test printing comprising image data of the pages of the document fed by the document feeder.

Printing symbols on media is described. Sequential parts of a symbol are marked onto each of multiple corresponding sequential segments of the medium. A characteristic of each of the sequential symbol parts is evaluated. A speed is monitored with which the medium is moved upon the marking of each of the sequential symbol parts onto each of the corresponding sequential segments of the medium. An image, captured in relation to the evaluation, is adjusted based on the monitored speed. Adjusting the captured image may include setting a rate at which the evaluation of the characteristic of each of the sequential symbol parts is performed based on the monitored speed or alternatively, predicting a distortion in the evaluated characteristic of each of the sequential symbol parts corresponding to the monitored speed, and applying a change to the captured image corresponding to, and ameliorating the predicted distortion.

An image inspection device includes a hardware processor. The hardware processor (i) captures a read image from a reading device, (ii) compares a reference image and an inspection image obtained by reading a paper sheet targeted for inspection on which an image corresponding to the reference image has been formed with the reading device, to inspect the inspection image, (iii) sets a first alignment region having a predetermined width on a leading end side of each of the reference image and the inspection image in a conveyance direction, and sets a second alignment region having a predetermined width on a rear end side in the conveyance direction, and (iv) corrects the reference image on a basis of amounts of positional deviation of the first alignment region and the second alignment region.

Techniques for interactively determining/visualizing the color content of a source image and how the corresponding image data is mapped to device colors are described herein. For example, the color content of a digital image can be converted between different color spaces to identify gamut limitations of an output device (e.g., a printing assembly), discover color(s) that cannot be accurately reproduced, etc. Color space conversions enable the transformation of the color content of the digital image from device-specific colorants to a device-independent representation (and vice versa). In some embodiments, these transformations are facilitated using lookup tables that are implemented in graphical processing unit-resident memory.

An image capturing unit includes a sensor unit that image-captures a predetermined area including a subject; and a reference chart unit that is arranged in the predetermined area and captured with the subject by the sensor unit.
