Manta Technical Manual V7.9.0
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 interpolation:
Figure 119: Bayer demosaicing (interpolation)
Figure 120: Bayer demosaicing (Manta type A cameras)
•
Note that on the color camera, an incorrectly 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 a region of interest, x and y resolutions must be even-numbered.
