Method for correcting chromatic aberration

The invention relates to a method for correcting chromatic aberration in an image capture device like a camera. It comprises the steps of determining, in the image, an analyzing area around the current pixel, comparing, for the current pixel, a first color component data of a first block of pixels c...

Beschreibung
Zusammenfassung:	The invention relates to a method for correcting chromatic aberration in an image capture device like a camera. It comprises the steps of determining, in the image, an analyzing area around the current pixel, comparing, for the current pixel, a first color component data of a first block of pixels comprising the current pixel to a second color component data of pixels of second blocks of pixels having the same size as the first block within the analyzing area, selecting the second block of pixels having the highest correlation with the first block of pixels, determining the shift vector to be applied to the selected second block in order that said selected second block coincides spatially with said first block of pixels, and shifting the second color component data of the pixel of the selected second block corresponding to the current pixel in accordance with the shift vector so as to correct chromatic aberration.
