Color processing apparatus and method that calculate and combine color data of diffuse reflection in a line-of-sight direction and color data of specular reflection in a line-of-sight direction, and that convert the combined color data to color data in a color space of a monitor
摘要:
A color processing apparatus configured to simulate a print product output by a printer on a monitor. The apparatus includes a first conversion unit configured to convert color data representing an image of the simulation object into color data in a printer color space, 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, a second calculation unit configured to calculate color data in the printer color space and specular reflection color data, 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 and color data of specular reflection, and a second conversion unit configured to convert the combined color data to color data in the monitor color space.
