METHOD AND DEVICE FOR SUPPRESSING CHROMATIC ABERRATION IN A DIGITAL IMAGE
Abstract:
A method for suppressing chromatic aberration, especially blue or red fringing, in a digital image with multiple color channels is disclosed. The method comprises negatively correcting a first color channel by subtracting an overshoot component of the first color channel. The subtraction is subject to a lower threshold, which is dependent on a local value of at least one further color channel.
