A method of compensating for nonuniformities in an image sensor includes: providing an image sensing device 20; measuring test pixel signals from the image sensing device 20 during a test mode; determining which test pixel signals are greater than a fixed threshold level ST; and calculating nonuniformity coefficients for the pixels having test pixel signals greater than the fixed threshold level ST.
