An information processing apparatus includes a processor configured to: receive an image; and in response to inputting a magenta component resulting from CMYK conversion of the received image, output the image having undergone color conversion performed by using a profile in which at least one of the magenta component and a pink component that leads to fluorescent color forming is output, in which in an area having an input magenta amount lower than a predetermined threshold, the magenta component is not output and only the pink component is output, the input magenta amount serving as an amount of the magenta component resulting from the CMYK conversion, and in which in an area having the input magenta amount higher than or equal to the threshold, the magenta component and the pink component are output.

A non-transitory computer readable medium storing a program causing a computer, which reproduces a color tone of a printed matter and displays the color tone on a screen before printing, to realize a function of generating an image in which the color tone of the printed matter is reproduced based on a first component reflected by a metallic color material and a second component transmitted through the color material and reflected by paper.

A color correction apparatus has: an obtaining unit that obtains first color information of a first image formed by a first color formed on a recording medium and second color information of a second image formed by a second color superimposed on the first color formed on the recording medium; and a correction unit that finds a correction value for the second color by estimating color information of the second color based on the first color information and the second color information, the color information of the second color being varied due to an influence in correcting the first color information to a first target value of the first color.

An image forming apparatus includes a first reading unit configured to read a first image on a first surface of a document, a second reading unit configured to read a second image on a second surface of the document different from the first surface, a printing unit configured to print a third image on a sheet, and a setting unit configured to set resolution of the third image printed by the printing unit. The printing unit prints the third image on the sheet with the resolution set by the setting unit. The printing unit also prints a fourth image with resolution lower than or equal to a threshold, without using the set resolution, the fourth image used for correction of at least a color value obtained by reading the second image using the second reading unit.

An example method comprises identifying a plurality of supply levels corresponding to a plurality of print supplies of a print device, and adjusting a color for a region of a print job for the print device based on the plurality of supply levels. The method further comprises initiating execution of the print job using the adjusted color for the region.

Techniques of color image processing involve performing a transformation for each color channel that mixes intensity values from other channels to produce a new intensity value for that channel. The new intensity values, representing the effect of overlapped response spectra of the S, M, and L cones, then provide values of the sensitivities of the photoreceptors of each of the cones. These values of the sensitivities form the basis of more accurate color image processing. For example, compression ratios of gamma-compressed color images may be increased when more the sensitivities are more accurate.

A color conversion table corrector corrects a color conversion table used in an image data generation device, and the color conversion table corrector includes a hardware processor that: obtains data related to a print image; obtains first target data based on a first captured image obtained by capturing an image of a first color matching target corresponding to the print image; decides a specific area, in the first captured image, which is not used to correct the color conversion table; and corrects the color conversion table according to the data related to the print image and the first target data based on the first captured image excluding the specific area.

Certain examples described herein relate to a color processing apparatus and a method of generating configuration data for a color rendering device. The color rendering device operates based on color state instructions indicating output color states for portions of a rendered output. Render data may be generated by applying a halftone matrix and color data may indicate probability values for the output color states for input image areas corresponding to the portions of the rendered output. In described examples, configuration data defines an order of output color states for application of the halftone matrix. In the order, the output color states are grouped within the data based on color properties of a rendered output and an order within the clusters is based on colorant composition.

To make it possible to specify a color space of image data even in a case where color space identification information is not attached to the image data. The image processing system that handles image data whose color spaces are different comprises a learning unit configured to perform machine learning by taking image data and metadata thereof as input data and color space identification information as supervised data. In the machine learning, a learning model is optimized so that a deviation between the color space predicted from the input data and the color space specified by the color space identification information becomes a minimum.

Systems and methods are disclosed for non-linear color correction. The method including receiving an input image from an image sensor, converting the input image from a red, green, blue (RGB) color space format to an alternate color space format, determining localized hue correction parameters for a selected color in the alternate color space, determining localized saturation correction parameters for a selected hue in the alternate color space, applying the localized hue correction parameters and the localized saturation correction parameters to the input image to generate an output image and storing, displaying, or transmitting the output image based on at least the localized hue correction parameters and the localized saturation correction parameters.
