Patent ID: 8902471

Claim:
A method comprising: identifying a plurality of sub-ranges of color values of a first color space, wherein the first color space is associated with a first device, the plurality of sub-ranges comprising an in-range sub-range for at least some color values within an intensity range associated with the first device and an over-range sub-range comprising at least some color values outside the intensity range associated with the first device; identifying an accuracy level for conversions between the first color space and a second color space of the color values in the over-range sub-range and an additional accuracy level for conversions between the first and second color spaces of the color values in the in-range sub-range, the second color space associated with a second device, the additional accuracy level being greater than the accuracy level for conversions of the color values in the over-range sub-range, wherein identifying the accuracy level and the additional accuracy level comprises: accessing a table including input color values and corresponding output color values, wherein a first pair of the input color values defines the over-range sub-range and a second pair of the input color values defines the in-range sub-range; determining the accuracy level based on a first difference between a first pair of output color values respectively corresponding to the first pair of input color values; and determining the additional accuracy level based on a second difference between a second pair of output color values respectively corresponding to the second pair of input color values, the second difference being greater than the first difference; and generating, by a processor, conversion information for converting the color values in the over-range sub-range of the first color space to corresponding color values in the second color space and additional conversion information for converting the color values in the in-range sub-range between the first and second color spaces, wherein the conversion information is generated based on the accuracy level and includes information for converting a color value in the over-range sub-range to a color value in the second color space and the additional conversion information is generated based on the additional accuracy level and includes information for generating a color value in the in-range sub-range to an additional color value in the second color space.
