Abstract: A surface material pattern finish simulation device includes: an incident light calculation unit (14) that calculates incident light information as information about incident light on each of pixels in the image of the finish of the pattern, from information including a normal vector map and light source information about a light source emitting light to be applied to the surface; a reflected light calculation unit (15) that calculates the radiance of reflected light from the surface for each of the pixels in the image of the finish of the pattern, from calculation information including the incident light information, the normal vector map, diffuse reflectance information in the picture, gloss information indicating the gloss of the surface of the surface material, and observation condition information about the surface material; and a display unit (18) that displays the image of the finish of the pattern on the surface of the surface material determined from the radiance of each of the pixels.
