Color Interpolation
Three methods are supported to interpolate missing R, G, or B for mosaic image data from pixel array
as follows.
a) 3x3 linear color interpolation
Interpolation is done by moving 3x3 interpolation window by one pixel horizontally and vertically
b) 1/4 subsampling color interpolation
Interpolation is done by moving 2x2 interpolation window by two pixels each time horizontally and
vertically. The equation for color interpolation in each 2x2 window is simple as follows.
R1
G1
G2
B1
R = R1
G = (G1 + G2)/2
B = B1
