Spyder 3 CL User's Manual PRELIMINARY 69
DALSA 03-032-20008-03
Purpose: Enables and disables FPN and PRNU coefficients.
Syntax:
epc i i
Syntax Elements:
i
FPN coefficients.
0 = FPN coefficients disabled
1 = FPN coefficients enabled
i
PRNU coefficients.
0 = PRNU coefficients disabled
1 = PRNU coefficients enabled
Example:
epc 0 1
7.6 End-of-line Sequence
Purpose: Produces an end-of-line sequence that provides basic calculations
including "line counter", "line sum", "pixels above threshold",
"pixels below threshold", and "derivative line sum" within the
region of interest. These calculations can be used to perform
aoc
algorithms or indicate objects of interest.
To further aid in debugging and cable/data path integrity, the
first three pixels after Line Valid are "aa", "55", "aa". Refer to the
following table. These statistics are calculated for the pixels
within the region of interest.
Syntax:
els i
Syntax Elements:
i
0
Disable end-of-line sequence
1
Enable end-of-line sequence
Notes:
• LVAL is not high during the end-of-line statistics.
Example:
els 1
Table 13: End-of-Line Sequence Description
Location Value Description
1 A’s
2 5’s
3 A’s
By ensuring these values consistently
toggle between "aa" and "55", you can
verify cabling (i.e. no stuck bits)
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)
6 Line sum (15…8)
7 Line sum (23…16)
8 Line sum (31…24)
Use these values to help calculate line
average and gain
