Using a minimal number of parameters for correcting the response of color image sensors

摘要

Methods for generating a set of parameters and an associated methodology that model a portion of the variation in a number of sensor-specific correction matrices. The parameters are fewer than the number of elements in one of the sensor-specific correction matrices yet adequately model variations in the IC manufacturing process used to fabricate color image sensors. Storage circuitry aboard an IC die containing the sensor can be configured to store the parameters.
