Table 13: End-of-Line Sequence Description
Location Value Description
1 A‘s By ensuring these values consistently
toggle between "aa" and "55", you can
verify cabling (i.e. no stuck bits)
2 5‘s
3 A‘s
4 4 bit counter LSB justified
Counter increments by 1. Use this value to
verify that every line is output
5 Line sum (7…0)
Use these values to help calculate line
average and gain
6 Line sum (15…8)
7 Line sum (23…16)
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)
Setting Thresholds
Setting an Upper Threshold
Purpose: Sets the upper threshold limit to report in the end-of-line
sequence.
Syntax:
