摘要:
Provided is a method and apparatus to perform gamut mapping between heterogeneous devices, more particularly, a method and apparatus to map a color of a device to an identical or visually and sensually preferable color of another device having a different color gamut. The method includes adjusting lightness of a color of a source device by scaling to match a lightness range of the source device with a lightness range of a destination device; modifying the adjusted lightness of the color of the source device by adjusting a color gamut of the source device to a color gamut of the destination device; and to map the modified color of the source device to a color in the color gamut of the destination device.
摘要(中):
提供了一种用于在异构设备之间执行色域映射的方法和装置,更具体地,涉及将设备的颜色映射到具有不同色域的另一设备的相同或视觉和感官优选颜色的方法和装置。 该方法包括通过缩放来调整源设备的颜色的亮度,以使源设备的亮度范围与目的地设备的亮度范围相匹配; 通过将源设备的色域调整到目的地设备的色域来修改源设备的颜色的调节亮度; 并将源设备的修改颜色映射到目的地设备的色域中的颜色。
