Patent ID: 8520969

Claim:
An image-processing apparatus for processing a digital image in YCrCb color space, the image having an initial luminance plane Y and two initial Cr, Cb chrominance planes, the processing apparatus comprising: a first block configured to receive in input the initial luminance plane Y of the digital image, to process the initial luminance plane Y, and provide a modified luminance plane Y in output; a color artifact correction block configured to operate in parallel with the first block, the correction block configured to receive in input the initial planes Y, Cr, and Cb of the image, to modify the initial chrominance planes Cr and Cb through pixel-by-pixel processing with a mobile working window, the correction block including both a false colors correction sub-block and a purple fringing correction sub-block, the false colors correction sub-block and the purple fringing correction sub-block being configured to modify values of the initial Cr and Cb chrominance planes based on information contained in the initial Cr and Cb chrominance planes and also based on information contained in the initial luminance plane Y.
