1. A digital image system for correcting sensor values generated by pixels within an array of pixels, each of said pixels within said array of pixels producing a respective one of said sensor values for an image, said digital image system comprising: a buffer for storing at least a portion of said sensor values produced by said pixels for said image, one of said stored sensor values being a current sensor value in a first color plane produced by a current one of said pixels; and a processor connected to receive said sensor values stored in said buffer, compute interpolated sensor values in said first color plane for said pixels spatially adjacent to said current pixel using said stored sensor values and determine whether said current pixel is defective using said interpolated sensor values.
