发明名称 Luminance conversion of material color and light source color
摘要 An image processing method whereby when a display of a light source color to display a visible image by a color generation and a display of a material color to display a visible image by depositing a coloring agent onto a material to be recorded are color matched, a luminance component of the material color display is corrected so as to be larger than the luminance component of the light source color display. The correction of the luminance component is executed after converting into color space signals which don't depend on characteristic of the visible image display apparatus to be used. The luminance component is raised in the conversion from an input signal of the light source color display into an output signal of the material color display and the luminance component is reduced in the conversion from an input signal of the material color display into an output signal of the light source color display.
