Abstract
A method for providing combined gain compensation and error correction for a camera pickup array includes assigning and storing. The act of assigning assigns a memory location that accommodates for storing a representation of a multibit gain value to each relevant pixel in the array, assigns a first value range in the location to a range of feasible pixel gain values, and assigns at least one second value in the location to a faulty gain value. The act of storing includes storing pixel values for a multi-pixel image and reading out the multi-pixel image while compensating to a standardized image value for feasible gain values but accessing a correction algorithm for a faulty pixel gain value.
