Abstract
Methods, apparatuses and systems for storing approximations of multiple spatial pixel value adjustment surfaces for use in pixel value correction. The adjustment surfaces may be used for positional gain adjustment. A representation of the multiple adjustment surfaces is stored as coefficients representing a multi-dimensional solid of two-dimensional adjustment surfaces. The stored coefficients are used to determine a plurality of additional sets of coefficients which sets are then in turn used to determine pixel correction values of adjustment surfaces.
