Claim:
A specular gloss simulation device for simulating specular gloss by measuring, in a given geometry, luminance of a sample that has a base material and a colorant material layer formed on the base material, and then simulating a specular reflection light amount in an other geometry from the thus measured luminance, the specular gloss simulation device comprising: a lower layer reflection light component creating section for calculating a lower layer reflection light component from base material luminance, where the base material luminance is luminance of only the base material measured in a plurality of geometries, and the lower layer reflection light component is a component being reflected on the base material and transmitting through and out of the colorant material layer; an internal reflection light component creating section for measuring luminance of the sample in the given geometry, and for creating an internal reflection light component from the measured luminance and the lower layer reflection light component, where the internal reflection light component is a component being reflected from an interior of the colorant material layer; a surface reflection light component creating section for measuring luminance of the sample in the given geometry, and for creating a surface reflection light component from the measured luminance, the lower layer reflection light component, and the internal reflection light component, where the surface reflection light component is a component being reflected on a surface of the colorant material layer; and a specular reflection light amount calculating section for obtaining a specular reflection light amount of the sample from the components thus created by the lower layer reflection light component creating section, internal reflection light component creating section, and surface reflection light component creating section.
