Abstract
A method for correcting image data, in particular for color correction and cross-talk reduction of image data obtained by an image sensor comprising image pixels (R, G, B) and non-image pixels (F), the image pixels (R,G,B) being overlaid with a color filter array (CFA) and having a different spectral sensitivity than the non-image pixels, comprises determining a set of color components (rold, gold, bold) for the image pixels (R,G,B) based on raw image data (rraw, graw, braw) read only from the image pixels (R,G,B) of the image sensor (); correcting the set of color components of non-direct neighbors of the non-image pixels (F) by means of a first color correction matrix (CCM); and correcting the set of color components of direct neighbors of the non-image pixels by means of a second color correction matrix (CCM) different from the first color correction matrix. An image sensor () and an auto-focus camera using same are also disclosed.
