Window pulse output WIND1 : When connected to EEST (pin 2), the
operation of electronic exposure can be
stopped at the upper side of monitor.
WIND2 : A pulse that picks out the center of the CCD
output. At this time, set H level or open at EEST
(pin 2). As the output circuit of WIND is N-ch
open drain, connected to VDD with R (≥ 47 k$).
4 TVMD
