In color interpolation a red, green or blue value is determined for each pixel.
Only two lines are needed for this interpolation:
Figure 92: BAYER demosaicing (interpolation)
Formula 4: BAYER demosaicing
Note
Please note that on the color camera, a wrongly colored
border of one or two pixel wide forms on the left and right
image borders. This is also a consequence of BAYER dem-
osaicing as the image width displayed on the color camera
is not scaled down.
