A color conversion correction data generation device includes circuitry that acquires first chromaticity values obtained from conversion target image data and second chromaticity values of sample image data, the conversion target image data being image data to be subjected to color conversion, the sample image data being obtained by reading a printed sample; curve-fits chromaticity value correspondence data to generate color conversion correction data, the chromaticity value correspondence data being data in which the acquired first chromaticity values and the acquired second chromaticity values are associated with each other; and outputs the color conversion correction data for correcting image data obtained by subjecting the conversion target image data to the color conversion.

A transform wrapper is stored on a memory device and the memory device may be included in a printer cartridge. The transform wrapper may dynamically build a transform map for a printer based on metadata stored at the memory device. The metadata may indicate at least one of a type of depositing material, transform map, print media and printer.

Disclosed are an interface display method, a device and a storage medium. The method includes: obtaining a color-blind color of a current user and a current color replacement mode; determining a target color corresponding to the color-blind color when the current color replacement mode is a user-defined mode; and replacing the color-blind color displayed on a display interface of a smart device with the target color when the display interface is activated, and displaying the target color on the display interface. The present application determines the color-blind color of the current user and replaces the color-blind color with the target color which is determined in a specific color replacement mode, and finally no color-blind colors are displayed on the display interface, the viewing experience of the achromate is improved.

Luminance data indicating luminance of the print product illuminated by the lighting is calculated and processing for causing a high luminance region to have gradation characteristics is performed.

Systems and methods manage information relating to paper media to enhance the quality of printing by printers. Systems and methods efficiently maintain color management profiles for different papers and ensure that the most appropriate (e.g., optimal) color management profile is employed for color conversion on a specific paper. In particular, embodiments may employ dynamic management of data stored in paper catalogs of printing systems. As such, a paper catalog of a printer device can effectively associate a paper with a color management profile that provides the best possible color reproduction on that paper.

An image processing apparatus generates, from a mixed image of projection images projected from a plurality of projection devices, separated images for respective pieces of color information, on the basis of a color model. For the color model, the pieces of color information of the projection images changed according to spectral characteristics of the projection devices and an image pickup device for acquiring the captured image and an attenuation coefficient are used as parameters, and a color separation processing section generates the separated images for the respective pieces of color information on the basis of the color model, by using parameters that minimize the difference between the color information of the captured image and color information estimated by the color model. The image processing apparatus becomes able to accurately separate projection images from the captured image of the mixed image including a plurality of projection images.
