ABSTRACT:
Provided are a method, system, and article of manufacture for converting image data in an input color space to an output color space in a transform domain. An input block of coefficients in an input color space is generated, wherein the input block includes a first type coefficient and a plurality of second type coefficients. The first type coefficient in the input block is converted to an output value in an output color space. The output value is used to determine a scaling factor for the second type coefficients. The scaling factor is applied to the second type coefficients to determine second type coefficients in the output color space. A component output block of coefficients in the output color space is formed from the output value for the first type coefficient and the determined second type coefficients in the output color space.
