Abstract
Systems, articles and methods to provide lens shading color correction using block matching are disclosed. Example processor systems disclosed herein include memory to store first shade correction data. Disclosed example processor systems also include processor circuitry to cluster blocks of an image into at least one cluster based on a criterion, process the at least one cluster to determine at least one modification parameter, modify the first shade correction data with the at least one modification parameter to determine second shade correction data, and correct a lens shade effect associated with the image based on the second shade correction data.
