Abstract
A scene balance correction method for a digital imaging device, including the steps of determining a low-resolution image from an input image in an input color space; applying a color transformation to convert the low-resolution image to a standard color space to form a standard color space low-resolution image; analyzing the standard color space low-resolution image to determine a set of standard color space scene balance correction factors; determining a set of corresponding input color space scene balance correction factors from the standard color space scene balance correction factors using the color transformation; and applying the corresponding input color space scene balance correction factors to the input image to form a corrected input image.
