3.4.3 End-of-line Sequence
Pu rp ose:
Prod u ces an end -of-line sequ ence that p rovid es basic calcu lations
inclu d ing "line cou nter", "line su m ", "p ixels above threshold ",
"p ixels below threshold ", and "d erivative line su m " w ithin the
region of interest. These basic calcu lations are u sed to calibrate
analog offset (
cao
) and calibrate analog gain (
ccg
).
To fu rther aid in d ebu gging and cable/ d ata p ath integrity, the
first three p ixels after Line Valid are "aa", "55", "aa". Refer to the
follow ing table. These statistics refer only to p ixels w ithin the
region of interest.
