Abstract
A compensating technique, implemented as an image processing block inserted in a chain of sequential image processing blocks, is used to achieve custom tuning at an end-user site to provide a customer a desired image quality (IQ) different from the factory calibrated one, or to simply compensate for drift in the image quality due to a number of factors including environmental conditions and/or system aging. The compensating techniques use a higher order polynomial to correct an actual input/output parameter relationship such that it is acceptably close to a pre-determined input/output parameter relationship for a given measurable parameter related IQ.
