ABSTRACT:
Methods, systems and apparatuses for determining and compensating for green imbalance in imagers. An estimated local green balance correction term is limited, e.g., between an upper and lower limit. The upper and lower limits are determined from a set of parameters. The parameters are determined during a calibration procedure. The parameters may be stored for a subset of possible pixel locations and parameters for each pixel not at a location corresponding to stored data may be determined by interpolation.
