Abstract
High dynamic range (HDR) imaging has been developed for acquiring scene with a high dynamic range. Tone-mapping operators are used to reproduce the dynamic range of HDR content on a low dynamic range (LDR) devices. iCAM06 is a tone-mapping algorithm based on the color appearance model. iCAM06 contains chromatic adaptation and tone compression; however, the chrominance component of the chromatic adaptation is not preserved after tone compression. This paper describes a novel decoupled processing for the chromatic adaptation and tone compression to preserve the chrominance component and reduce the color distortion of iCAM06. Further, a color appearance model is used to separate and combine the chrominance and luminance components of the decoupled processes. The rendered results confirm that the proposed algorithm is superior to the conventional algorithm.
