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.
