Abstract:
1. A method of pixel correction, comprising 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 said sensor; (C) generating a per-pixel correction model by decompressing information using a particular decompression method, wherein (a) said particular decompression method is selected from a plurality of decompression methods by looking up indices from a lookup table based on said temperature signal, (b) said per-pixel correction model comprises a plurality of gain values and a plurality of offset values and (c) said information has a single fixed pattern noise model; and (D) generating a plurality of corrected values by correcting a respective gain and a respective offset in each of said pixels values using a corresponding one of said gain values and a corresponding one of said offset values of said per-pixel correction model.
