Abstract
A method for correcting white balance in a captured digital image includes storing raw sensor data representative of the captured digital image in a memory and normalizing the raw sensor data by applying an illuminant-independent shading and vignetting correction to the raw sensor data. The method continues with applying a plurality of illuminant-dependent shading and vignetting correction masks to the raw sensor data and comparing the illuminant-dependent shading and vignetting correction result with the illuminant-independent shading and vignetting correction result.
