Abstract
A color interpolation technique may use a Bayer matrix or pattern. In one embodiment, a color intensity gradient may be calculated between data from a center pixel in the Bayer pattern and the sensor spaced from the center pixel. A minimum and maximum gradient for a plurality of pixels may then be determined. Minimum and maximum intensity values for a group of pixel data values may be determined and these may be averaged to determine a value which may be utilized for interpolation purposes. The technique can use only a simple shift and does not require large dividers.
