Enabling and Disabling Pixel Coefficients
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
A2.3 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 basic calculations are used to calibrate
analog offset (
103H
cao
) and calibrate analog gain (
104H
ccg
).
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 refer only to pixels within the
region of interest.
Syntax:
els i
Syntax Elements:

0
Disable end-of-line sequence
1
Enable end-of-line sequence
Notes:
•
LVAL is not high during the end-of-line statistics.
Example:

Table 12: 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
