Abstract
A method of pixel correction is disclosed. The method generally includes the steps of (A) generating a plurality of pixel values from a sensor in response to an optical signal, (B) generating a temperature signal representing a temperature of the sensor and (C) generating a plurality of corrected values by applying a per-pixel correction model to the pixel values, wherein the per-pixel correction model is responsive to the temperature.
