Claims
- 1. An image processing method for matching color appearance between a light source color being the color reproduced by a display device and a material color being the color reproduced on a recording medium, comprising:a luminance component conversion step of performing a correction process resulting in a luminance component of color data for reproducing a body color that is greater than a luminance component of color data for reproducing the light source color; a conversion step of performing a conversion process according to input and output light source information; and an equipment characteristic conversion step of converting device-dependent color data into device-independent color data.
- 2. A method according to claim 1, wherein said luminance component conversion step inputs color data of an XYZ color system and multiplies each of X, Y, and Z components by a predetermined coefficient.
- 3. An image processing method for matching color appearance between a light source color being the color reproduced by a display device and a material color being the color reproduced on a recording medium, comprising:a luminance component conversion step of performing a correction process resulting in a luminance component of color data for reproducing a body color that is greater than a luminance component of color data for reproducing the light source color; and a conversion step of performing a conversion process according to input and output light source information, wherein said conversion step performs Von Kries conversion.
- 4. An image processing apparatus for matching color appearance between a light source color being the color reproduced by a display device and a material color being the color reproduced on a recording medium, comprising:a luminance component conversion unit for performing a correction process resulting in a luminance component of color data for reproducing a body color that is greater than a luminance component of color data for reproducing the light source color; a conversion unit for performing a conversion process according to input and output light source information; and an equipment characteristic conversion unit for converting device-dependent color data into device-independent color data.
- 5. An image processing apparatus for matching color appearance between a light source color being the color reproduced by a display device and a material color being the color reproduced on a recording medium, comprising:a luminance component conversion unit for performing a correction process resulting in a luminance component of color data for reproducing a body color that is greater than a luminance component of color data for reproducing the light source color; and a conversion unit for performing a conversion process according to input and output light source information, wherein said conversion unit performs Von Kries conversion.
