(5-3) Programmable partial
[Option]
By designating the high-speed transfer portion with external PARTIAL signal input, the
camera read out only the portion of CCD area necessary for your application. This is
available under ext. sync.

The starting point of external partial signal is [

z
The external partial signal is controlled at each ext. HD falling edge. Set the start / finish of
the external partial signal in 1H increments.
z
The number of 1H high-speed transfer line is 10 lines. The actual lines are determined by
the external partial signal “hi” period. (Minimum: 2H = 20 lines)
z
Set video output time more than 30H. And high-speed transfer time (the external partial
signal “hi” period) before video output time is is as follows;
from 2H through 22H under 1/60s non-interlace mode
from 2H through 11H under 1/120s interlace mode
z
After high-speed transfer, 2H is allocated to blank transfer period. Normal transfer starts at
the next line.

VIDEO OUT vertical blanking is;
V. blanking = [

Example follows below.
(High-speed 2H = 20 lines (minimum), Normal-speed 70 lines + BLK 2H)
