In some examples, a computing device includes a first display device coupled to a second display device by hinges. After determining that the computing device has been moved from a first orientation to a second orientation, the computing device may receive ambient light data from ambient light sensors associated with the first and second display device, temperature data from temperature sensors associated with the first and second display device, and color data from color sensors associated with the first and second display device. After determining that power is being received from an external power source or that the user prefers the display devices may be color matched, the computing device may perform one or more color adjustments based on the ambient light data, the temperature data, and the color data, thereby reducing a difference in a perceived color between the first display device and the second display device.

An image data generating method of generating an image from a document includes acquiring, based on light reflected by the document, a first image signal corresponding to a plurality of components in a plurality of visible wavelength ranges and a component having a reflection absorption characteristic in an invisible wavelength range, converting the first image signal into a second image signal including a plurality of device-independent color space components and a black component, and generating image data based on the second image signal.

Methods, systems and computer readable media for color management are described. In some implementations, the method can include accessing one or more buildup curves associated with a combination of a substrate, one or more colorants and a colorant dispenser. The method can also include accessing a design file specifying a design and including one or more layer files each specifying a layer color. The method can further include generating, for each layer color, a corresponding colorization recipe based on the one or more buildup curves. The method can also include creating a production job instruction/metadata file having a link to the design instruction/metadata file and including parameters associated with the colorant dispensing job to be carried out using the design instruction/metadata file.

In an output profile representing a correspondence relationship between device independent coordinate values and second coordinate values in a second device dependent color space, a color conversion table used to convert the device independent coordinate values into the second coordinate values is defined as a first conversion table, and the device independent coordinate values at the adjustment point are defined as to-be-adjusted PCS values. In optimization, an optimization process including an element making provisional color values closer to an adjustment target is executed, the provisional color value being acquired by a conversion, in accordance with the first conversion table, of provisional PCS values resulting from a change in the to-be-adjusted PCS values, thus acquiring an optimal solution for the device independent coordinate values corresponding to the adjustment target.

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.

An aspect of present principles is directed to methods and systems for gamut mapping source colors into target colors from a source color gamut towards a target color gamut. A difference may be determined source specific colors and corresponding target specific colors. A source hue of the source specific colors is adaptively changed towards a target hue of the corresponding target specific colors based on the difference to determine mapped specific colors. Color gamut mapping is performed for the source colors of the source color gamut towards the target color gamut based on the mapped specific colors. The specific colors are selected from primary colors, secondary colors, a group of primary colors and secondary colors. The difference is based on at least one selected from the group of hue, saturation and lightness of the source specific colors and the corresponding target specific colors.

An image processing apparatus for displaying an image on a display screen, inputs data, specifies at least one of a bright region and a dark region of an image corresponding to the image data, executes, for at least one of the bright region and the dark region, at least one of first chroma processing of increasing a chroma of the bright region, second chroma processing of lowering the chroma of the dark region, first hue processing of making a hue of the bright region close to red, and second hue processing of making the hue of the dark region close to blue in accordance with display dynamic range information corresponding to the display screen, and displays, on the display screen, an image based on corrected image data that has undergone correction.

In some implementations, a method includes: obtaining a first image; determining characterization properties for each of a plurality of pixels within the first image; determining a dominant hue based on the one or more characterization properties for each of the plurality of pixels within the first image; determining a plurality of hues that satisfy a predetermined perception threshold relative to the dominant hue based on the characterization properties for each of the plurality of pixels within the first image, wherein the plurality of hues is different from the dominant hue; and generating a second image based at least in part on the dominant hue and the plurality of hues. In some implementations, the second image corresponds to a color gradient generated based on the dominant hue within the first image. In some implementations, the second image is set as a wallpaper for a user interface.

A print data generator includes a storage storing processor-executable instructions causing a processor to perform a process to generate print data from original full-color data. The process includes when a hue value of a pixel is within a specific hue range for an emphasis color, setting a density value of a reference color of the pixel based on a value value of the pixel, and setting a density of the emphasis color of the pixel based on a saturation value of the pixel and a difference value between the hue value of the pixel and a hue value of the emphasis color, and when the hue value of the pixel is out of the specific hue range, setting the density value of the reference color based on a luminance value of the pixel derived from RGB data, and setting the density value of the emphasis color to zero.
