Patent ID: 8493618

Claim:
A color processing apparatus configured to simulate a print product output by a printer on a monitor, the color processing apparatus comprising: a first conversion unit configured to convert color data representing an image of the simulation object into color data in a printer color space based on an illumination condition and a printer profile; a first calculation unit configured to calculate color data of diffuse reflection in a line-of-sight direction from color data in the printer color space using a diffuse reflection table corresponding to the illumination condition; a second calculation unit configured to calculate color data in the printer color space and specular reflection color data using a specular reflection table corresponding to the illumination condition; a third calculation unit configured to calculate color data of specular reflection in a line-of-sight direction from color data of specular reflection calculated using a parameter representing an exitance of the glossiness and colorless light-source color data; a combination unit configured to combine the color data of diffuse reflection in a line-of-sight direction and color data of specular reflection in a line-of-sight direction; and a second conversion unit configured to convert the combined color data to color data in a color space of the monitor.
