Abstract
In one implementation, an image sensor is calibrated by determining a spectral characterization for each image window of an image sensor, correlating the spectral characterization for each image window of the image sensor with a spectral property of a target illuminant, and generating a scale factor for each image window of the image sensor. The scale factor for each image window of the image sensor is generated based on the correlating.
