An information processing apparatus is provided to facilitate a user's understanding of which area of an image has a higher degree of change when image processing is performed on the image. The information processing apparatus displays, on a display device, information indicating a relationship in magnitude between a first amount of change by the image processing in a first area included in a predetermined image and a second amount of change by the image processing in a second area included in the predetermined image.

There is provided a method for filling at least one color in one or more outline images at a multi-function device. The method includes providing a user interface for displaying a color fill option. Based on receiving a selection of the color fill option, a file including at least one outline image is received by a controller. The at least one outline image includes at least one image field. Then, it is identified by an image processor, if the at least one image field includes at least one color marking. Based on the identification, the at least one image field is automatically filled by the image processor according to the at least one color marking to generate a color filled image.

The present document provides image processing methods and apparatus. One claim recites: obtaining a signal to be encoded in color image data, the signal comprising a plural-bit payload; predicting a resulting color of overprinting several inks on a substrate, the overprinting representing the color image data encoded with the signal; using the resulting color for both i) visibility evaluation of the overprinting, and ii) signal robustness evaluation of the overprinting as seen by an imaging device. Other claims and combinations are provided.

A color information display device includes an extracting unit that extracts a reference color combination corresponding to reference color vision characteristics; an output unit that outputs the reference color combination as it is or after conversion in accordance with a degree of sharing of an impression of the reference color combination between the reference color vision characteristics and other color vision characteristics; and an assigning unit that assigns information indicative of the degree of sharing of the impression to the output reference color combination.

A method for inkjet printing machine color control includes color transformation of print data from first color space to process color space in a first stage using a computer transforming print data from the first to an intermediate color space while keeping special colors, and a second stage transforming corrected print data including special colors from intermediate to process color space. The computer uses print data corrected after the first stage as second stage starting values. Print data transformed into the process color space are printed. First color space corresponds to CMYK, flexographic printing or RGB color space with special colors, intermediate color space corresponds to CMYK color space with special colors, process color space corresponds to CMYK color space with additional process colors. The computer corrects CMY, not K print data or special not transformed colors, when correcting print data in the intermediate color space after the first stage.

Disclosed herein are system, method, and computer program product embodiments providing interface color branding. An embodiment operates by receiving a primary color associated with a theme of a user interface. A first color code corresponding to the primary color is determined. The first color code is converted into a second color code corresponding to the primary color, wherein the first color code is in a device-dependent color format and the second color code is in a device-independent color format. A secondary color corresponding to each of one or more portions of the user interface is derived from the second color code. Each secondary color is converted from the device-independent color format into the device-dependent color format. The one or more portions of the user interface are colored in the device-dependent color format.

The present disclosure relates generally to encoding signals for spot colors. In one implementation a substitute spot color+CMY tint is selected to replace an original spot color. The CMY tint can be transformed to carry an encoded signal. Of course, other features, combinations and technology are described herein.

An image forming apparatus to display an image, includes a controller, a touch panel display, a color change location specification part, and an approximate color image generator. The controller allows the touch panel display to display a preview image based on image data, selects a specific location of the preview image displayed by the color change location specification part, generates an approximate color image including an approximate color of the specific location selected by the approximate color image generator, and changes a color of an area including the specific location to a color selected from the approximate color image.

According to an embodiment, an image processing apparatus includes a display device and a processor. The display device displays a first image corresponding to first image data based on a document to be adjusted, and a second image corresponding to second image data based on a document for comparison. The processor creates a first conversion table by calculating a color value defined in a first color space and corresponding to a first position specified in the displayed first image, and a color value defined in the first color space and corresponding to a second position specified in the displayed second image.
