The image processing apparatus includes: an abnormality detection unit configured to detect one or more abnormalities included in a target image and an abnormality exclusion processing unit configured to exclude a specific abnormality from the detected one or more abnormalities. In a case in which a detection area of a certain abnormality among the detected one or more abnormalities and a detection area of another abnormality overlap with each other and a type of the certain abnormality and a type of the another abnormality are different from each other, when brightness information of one of the certain abnormality and the another abnormality satisfies a specific condition, the abnormality exclusion processing unit excludes the one of the certain abnormality and the another abnormality from the detected one or more abnormalities.

A print process control system includes a plurality of printing devices and an order management system to manage print jobs to the printing devices. Each printing device has an achievable quality level corresponding to its ability to meet color printing requirements. Job data for a print job is parsed to identify spot colors related to colors to be reproduced at the printing device. The printing device receives a test chart with color patches for the spot colors. Measurement data is captured from the color patches of the test chart. Using the measurement data, the order management system confirms whether the printing device can reproduce the spot colors according to a required level of tolerance or quality level.

An original image is read as an aggregate of a plurality of pixels in which adjacent pixels have different colors (R, G, and B) in a main scanning direction and in a sub-scanning direction, and the read pixels of the respective colors are stored in a line memory in association with information on relative positions of the pixels with respect to another pixel. Then, the stored pixels are sorted so that pixels having the same color are adjacent to each other, and an abnormal pixel (dust) not present in the original image is detected based on the state of the sorted pixels. With this, the dust not present in the original image is detected without increasing the cost, and the dust is corrected without forming a conspicuous trace of correction.

An information processing apparatus includes circuitry. The circuitry acquires a first state parameter indicative of a state of a printer engine of an image forming apparatus. The circuitry performs comparison between the first state parameter acquired and each of second state parameters registered in a memory in advance and indicative of states of the printer engine of the image forming apparatus at creation of a plurality of color profiles. The circuitry searches for a color profile corresponding to a second state parameter closest to the first state parameter from among the second state parameters.

A colorimetric device and a colorimetric method according to the present invention extract a chart region candidate, which is a candidate for a chart region, from an image of a color chart, obtain an evaluation value of this chart region candidate, determine whether or not the chart region candidate is the chart region based on this obtained evaluation value, obtain each position of a plurality of patches for the chart region candidate determined as the chart region as a result of the determination and colorimetrically measure each of the patches at each obtained position of the plurality of the patches.

According to the present disclosure, an image-processing apparatus acquires scan information of the read images read by the image-reading apparatus, generates temporal change data based on the statistical information and the scan information, determines whether the temporal change data satisfy a threshold, and outputs notice information when the temporal change data are determined as failing to satisfy the threshold.

A color verification optimization program causes a computer to execute a process including steps of, when a plurality of color conversion patterns are extracted, determining whether one color conversion profile and another color conversion profile coincide with or approximate to each other by comparing color saturation values which are estimated with respect to color conversion profiles, determining whether one color correction table and another color correction table coincide with or approximate to each other by comparing color saturation values which are estimated with respect to color correction tables, and performing control to perform verification on one color conversion pattern in two or more color conversion patterns of which the color conversion profiles and the color correction tables both coincide with or approximate to each other and omit the verification with respect to a remaining color conversion pattern.

An image processing apparatus includes a decomposition unit configured to decompose a color image into at least two color component images, a first obtaining unit configured to obtain a skewness of a histogram corresponding to each of the color component images, and a determination unit configured to determine based on the obtained skewnesses associated with the color component images whether the color image is glossy.

A display control apparatus is configured to display on a display unit a user interface screen for an image data generating apparatus configured to generate image data using an image sensor. The display control apparatus includes a setting acquiring unit which is configured to acquire a setting value for generating the image data, a display determining unit which is configured to determine whether to display an update reception screen based on the acquired setting value, a display control unit which is configured to display the update reception screen on the display unit if the display determining unit determines to display the update reception screen, and is configured not to display the update reception screen on the display unit if the display determining unit determines not to display the update reception screen, and an instruction receiving unit which is configured to receive the update instruction through the update reception screen.

An image processing apparatus for converting color data into gray data extracts an object included in the color data in a page, and determines, based on color information and position information on a first object and a second object extracted, whether at least one of the first object and the second object is to be a target of conversion of a color value of the color data into a gray value with improved discriminability. The image processing apparatus controls to convert the color value of the object into a gray value by a conversion targeting all color values, or into a gray value with the improved discriminability, based on the determination whether or not to be the target of conversion.
