A method for generating color conversion information including providing a user with color sample information for determining a color sample of which color characteristic information is known, receiving, from the user, an image including the color sample determined by the color sample information in a lighting environment, and generating color conversion information which corresponds to the lighting environment and is correlated with the user, based on the image and the color characteristic information of the color sample determined by the color sample information. The color conversion information converts between color information and color characteristic information, the color information is information which corresponds to a lighting environment and indicates colors of an object in the lighting environment, and the color characteristic information indicates color characteristics of the object.

Color conversion information generation method, color conversion information generation system, and program therefor

A device for generating a simulation image including circuitry which obtains information including normal vector map and light source information about a source of light to be applied to a surface of a material, calculates incident light information about incident light to each of pixels in an image to be generated as simulation of a finish of a pattern including a picture and an uneven shape on the surface, calculates a radiance of reflected light from the surface with respect to each of the pixels in the image, based on calculation information including the incident light information, the normal vector map, diffuse reflectance information about the picture, gloss information indicating gloss of the surface, and observation condition information about the material, and controls display of the image based on the radiance of each of the pixels.
