Abstract
A method for correcting for hue artifacts captured by an imager associated with a color filter array including first, second and third color pixels and optical system spaced from the imager, wherein a first group of second pixels are primarily influenced by adjacent first pixels and a second group of second pixels are primarily influenced by adjacent third pixels, includes separately blurring or smoothing the first and third pixels and the first and second group of second pixels; based on the difference between adjacent pixels of the first and second group of second pixels, correcting for hue in the second group of second pixels; and correcting for adjacent third pixels based on the correction for adjacent second group second pixels.
