The exposure time is controlled automatically to obtain the video level set.
It is possible to select the exposure time from eight speed settings; OFF (1/60s), 1/100s,
1/250S, 1/500S, 1/1000s, 1/2000S, IMOOOs, 1/IOOOOs.
Note:
When setting a rapid shutter speed, sensitivity degrades according to the speed.
When a discharging light such as fluorescent lamp, etc. is used for the illumination,
the flicker may be large.
Shutter speed can be set by the horizontal scanning time (1H) unit or by the frame unit.
Exposure is performed and images are output by external trigger. EXT TRIG includes the
four modes described below. (For details of specifications, refer to the item “7.5 EXT TRIG
(External trigger)”.)
•1 PULSE SNR(1 Pulse Sync Non Reset)
The charge begins to accumulate after the trigger pulse is received, and 1 field images are
output according to the internal vertical sync signal timing. The exposure/accumulation time
can be set from 0.06 to 16 ms. The trigger signal timing can be set to either the rising or
falling edge.
• 1 PULSE SR(1 Pulse Sync Reset)
The charge begins to accumulate after the trigger pulse is received. Upon completion of
accumulation the vertical sync signal is reset and 1 field images are output. The
exposure/accumulation time can be set from 0.06 to 16 ms. The trigger signal timing can
be set to either the rising or falling edge.
•2 PULSE
The charge begins to accumulate after the trigger pulse is received. Upon completion of
accumulation the vertical sync signal is reset and 1 fieid images are output. The
exposure/accumulation time is the time from when the first trigger signal is taken in until
the next trigger signal is taken in. The trigger signal intake timing can be set to one of
three settings: rising edge, falling edge or pulse width (front and back edges of pulse).
•RS232C
Accumulation of charges is started and ended by RS232C external control command
input, and 1 field images are output without changing the vertical sync signal timing.
