An information processing apparatus includes a display and a controller. The display displays an image. The controller controls the display to display a color setting section that sets information regarding a selected color selected from among multiple predetermined colors, and an effect presenting section that presents visual effect information representing a visual effect of the selected color.

The disclosed computer-implemented method may include generating color schemes. In some embodiments, the systems described herein may generate a color scheme by plotting non-linear curves through various planes that each represent an attribute of a color, selecting points on the curves, and generating colors from the values of the points. By generating colors schemes based on non-linear curves, the systems described herein may easily and efficiently generate aesthetically pleasing color schemes with colors predictably clustered in light and dark luminosities, facilitating the creation of user interfaces that are accessible to visually impaired users. Various other methods, systems, and computer-readable media are also disclosed.

A color gamut mapping method and a color gamut mapping device is provided, the method includes: determining a mapping target color gamut; obtaining a Lab value of a color point in the original color gamut, and determining a coordinate position of the color point in a corresponding tone plane of the original color gamut; judging the color point position; determining an intersection of a horizontal line the color point located and a boundary of the original color gamut, and a boundary of the mapping target color gamut; and determining a mapping point of the color point on the boundary of the map target color gamut by a ratio of an area of a pattern formed by the intersection, and an intersection of the original color gamut and a coordinate axis, and a difference between the area of the original color gamut and the area of the mapping target color gamut.

An image forming system includes a first image forming apparatus, a second image forming apparatus, a determining unit, and a display unit. The first image forming apparatus includes a first image forming unit that forms an image with a first developer of a process color. The second image forming apparatus includes a second image forming unit that includes a second developer and that forms an image with the second developer. The second developer has characteristics different from characteristics of the first developer on a medium. The determining unit determines, on the basis of image formation conditions designated by a user, a printing order in which an image formed with the first developer and an image formed with a second developer are printed on one medium, and determines a sequence in which the image forming apparatuses perform image formation on the basis of the determined printing order. The display unit displays the sequence determined by the determining unit.

A method is disclosed wherein data representative of a plurality of colors defined In a color space is received, the plurality of colors providing a color palette taken to be related to each other by predefined color harmony rules based on their relative positions in the color space. An irreproducible color of the color palette outside a rendering system's reproducible color gamut is determined, the reproducible color gamut having been received for a rendering system on which image data comprising colors of the color palette is to be reproduced. A suggested color for a replacement color palette also complying with the predefined color harmony rules is determined based on the reproducible color gamut to bring the color palette towards being within the rendering system's reproducible color gamut.

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.

Certain examples described herein relate to halftone level adjustment for Neugebauer Primaries (NPs). In certain examples, halftone levels for NPs are obtained for a halftone for printing an image. It is determined whether the halftone corresponds to a line or an area fill. The halftone levels may be adjusted in response to these levels exceeding a printing attribute threshold. The printing attribute threshold may be dependent on whether the halftone corresponds to a line or an area fill. The image may then be printed using the adjusted halftone levels.

Embodiments of the present invention disclose a method, computer program product, and system for cataloging images based on a gridded color histogram analysis. The computer accesses an image gallery specified by a user, wherein the image gallery is at least one of an image gallery stored on a user computing device, an image gallery stored on a user account at a third-party image storage, or an image gallery searched on the web. The computer receives a request to search the image gallery specified by the user. The computer performs a search of the image gallery, wherein the search is using a color based histogram algorithm based on a user input. The computer transmits a cataloged and sorted image gallery to the user computing device to be displayed.

Provided is an image forming apparatus that extracts an area indicated by a marker. A scanner unit reads a first document having an area indicated by a handwritten marker. A panel unit displays first image data of the first document read by the scanner unit or second image data of the second document stored in a storage device. An electronic marker input unit indicates an area by an electronic marker with respect to the second image data. An area extracting unit, based on a hue difference, which is a difference between a color of the first document read by the scanner unit and a color of the handwritten marker, corrects a hue difference, which is a difference between a color of the second document and a color of the electronic marker, and extracts an area indicated by the handwritten marker or an area by the electronic marker.
