Description
8
Line sum (31…24)
9
Pixels above threshold (7…0)
Monitor these values (either above or below threshold) and
adjust camera digital gain and background subtract to maximize
scene contrast. This provides a basis for automatic gain control
(AGC)
10
Pixels above threshold
(15…8)
11
Pixels below threshold (7…0)
12
Pixels below threshold (15…8)
13
Differential line sum (7..0)
Use these values to focus the camera. Generally, the greater the
sum the greater the image contrast and better the focus.
14
Differential line sum (15…8)
15
Differential line sum (23…16)
16
Differential line sum (31…24)
