Abstract
Provided are a method, system, and article of manufacture for determining whether to convert image data in an input color space to an output color space in a transform domain or real 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. A determination is made as to whether real domain processing is required. The input block is converted in a transform domain to an output block of coefficients in the transform domain in an output color space in response to determining that the output value does not require real domain processing.
