Description of the data path
In color interpolation a red, green or blue value is determined for each pixel
(P1= first pixel; P2= second pixel; etc). Only two lines are needed for this inter-
polation:
Figure 82: Bayer demosaicing (interpolation)
Formula 1: Bayer demosaicing (type A cameras)
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
demosaicing as the image width displayed on the color
camera is not scaled down.
•
Using ROI, x and y resolutions must be even-numbered.
