Methods and systems for detecting and correcting chromatic aberration and purple fringing are disclosed. Chromatic aberration can be addressed by separating an image into color planes and then adjusting these to reduce chromatic aberration by using a specific calibration image (calibration chart) as an empirical method to calibrate the image acquisition device. Purple fringing can be corrected by initially addressing color aberration resulting from the lateral chromatic aberration (LCA). The LCA is first removed and then the correction is extended to purple fringing. A discovery is relied upon that the purple fringing is created in the direction of the chromatic aberration and is more pronounced in the direction of the chromatic aberration.
A processor-implemented method of correcting lateral chromatic aberrations in digital images within a digital image acquisition device, comprising:
One or more non-transitory processor readable media having code embedded therein for programming a processor to perform a method of correcting lateral chromatic aberrations in digital images, wherein the method comprises:
A portable digital image acquisition device comprising a lens, an image sensor, a processor, and one or more processor readable media having code embedded therein for programming the processor to perform a method of correcting lateral chromatic aberrations in digital images, wherein the method comprises:
