1. A method for performing a white balance operation on an image, comprising: comparing a value of each pixel in the image against a value of every pixel for detecting the same color within a Chebyshev distance of at least one pixel to determine whether each pixel is substantially at or near the edge of a monochromatic region; selecting only pixels that are in either multichromatic or monochromatic regions and substantially at or near the edge of a monochromatic region; and using the selected pixels to obtain color balance information on the image.
