Patent ID: 7982928

Claim:
A system for colour correction of images, comprising a colour correction device adapted to correct at least one original colour in an original image, then generating corrected colours in a color corrected image, at least one reproduction device that is adapted to reproduce the colour corrected image, and that is calibrated by a reproduction forward transform that compensates for any characteristics of this reproduction device, a proof viewing device adapted to display the colour corrected image to a user, that is calibrated by a proof viewing forward transform that compensates for any characteristics of this proof viewing device, and a colour quality control device comprising a false contour detection unit adapted to use corrected colours and information from the reproduction forward transform and from the proof viewing forward transform to decide if a contour in the colour corrected image is a false contour, and wherein the false contour detection unit is adapted to: search for contours in the image of transformed reproduction colours; search for contours in the colour corrected image with corrected colours; and classify a detected contour in the image of transformed reproduction colours as a false contour if there is no corresponding contour detected in the colour corrected image with corrected colours.
