(9-5-3) 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
external sync.
(1/100s 2:1 Interlace mode)

(Conditions)
l
The starting point of external partial signal is 18.5 / 18H from the falling edge of ex-VD.
l
The external partial signal is controlled at each ex-HD falling edge. Set the start / finish of
the external partial signal in 1H increments.
l
The number of 1H high-speed transfer line is 18 lines. The actual lines are determined by the
external partial signal “hi” length. (Minimum: 1H = 18 lines)
l
After high-speed transfer, 2H is allocated to blank transfer period. Normal transfer starts at
the next line.
