<p>The invention discloses a method of managing color data based on color data in an HSaIn format in an HSaIn color space, comprising: acquiring color data in an XYZ format at an input device side; converting the acquired color data in the XYZ format at the input device side into color data in an HSaIn format. The method can further comprise mapping the color data in the HSaIn format at the input device side to obtain color data in an HSaIn format at an output device side; converting the color data in the HSaIn format at the output device side into color data in an XYZ format; converting the color data in the XYZ format at the output device side into one in a format of the color data of the output device. Since a conversion of chromatic color data independent of the device into chromatic color data dependent on the output device is achieved in this method, the output chromatic image is not influenced by color characteristics of the output device; and the analytical matrix operation adopted in the managing process is easily achieved, so the calculating process for the conversion is simple, the conversion accuracy and efficiency are improved, and the conversion speed is accelerated.</p> |
