1. A method comprising:
determining coefficients for implementing a kernel to be applied to pixel values derived, at least in part, from pixel signals of an imaging array to interpolate pixel values for a multi color channel imaging system, the coefficients to being determined based at least in part, on training operations, wherein:
the kernel is partitionable into a plurality of sub arrays, each sub array to map pixel values to pixel values of a color channel associated with the sub array such that:
a sum of coefficients of a first sub array of the plurality of sub arrays to map pixel values of a particular color channel substantially equals a first predetermined value; and
a sum of coefficients of at least one other sub array of the plurality of sub arrays to map pixel values of at least one remaining color channel other than the particular color channel substantially equals a second predetermined value.
