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.

A method for suppressing chromatic aberration in a digital image with multiple color channels, the method comprising negatively correcting a first color channel by subtracting an overshoot component of the first color channel, wherein the subtraction is subject to a lower threshold, which is dependent on a local value of at least one further color channel.
A non-transitory computer-readable storage medium having stored thereon instructions for implementing a method for suppressing chromatic aberration in a digital image with multiple color channels, when executed on a device having processing capabilities, the method comprising:
- negatively correcting a first color channel by subtracting an overshoot component of the first color channel, wherein the subtraction is subject to a lower threshold, which is dependent on a local value of at least one further color channel.
An image processing device for suppressing chromatic aberration in a digital image with multiple color channels, the image processing device comprising a memory and processing circuitry configured to perform a method for suppressing chromatic aberration in a digital image with multiple color channels, the method comprising:
- negatively correcting a first color channel by subtracting an overshoot component of the first color channel, wherein the subtraction is subject to a lower threshold, which is dependent on a local value of at least one further color channel.
