    Abstract

    A method (700) of processing an image (720) comprising a chroma channel (721) and a hue channel (722) to form a modified image (790), the method comprising the steps of determining (830), dependent upon the hue channel, hue-dependent spatial frequency information (750) characterising the chroma channel processing (760) the spatial frequency information dependent upon a Chroma Structure Model and a chroma processing specification (771); and forming the modified image dependent upon the processed spatial frequency information, the hue channel, and a lightness channel (723).
