7. Camera Function and Settings
7.1 Camera function
(7-1-1) GAIN selection
Switches sensitivity setting
(1-1) FIX ----------------------Factory-prefixed gain
(1-2) MANU------------------Gain is adjustable via the manual gain potentiometer (GAIN)
(7-1-2) Video output mode selection
Switches video format
(2-1) 1/60N : 1/60s-----------Non-interlace mode
As all pixels are read out in 1/60s, you will get images with the higher V
resolution.
(2-2) 1/120I : 1/120s--------- 2:1 interlace MIX mode
As vertical pixels are added in readout, the sensitivity is same as that of
1/60s non-interlace mode during electronic shutter OFF. Twice greater
sensitivity is obtained under shutter-speed range from 1/200 through
1/20000.
(7-1-3) TRIG selection
Switches TRIG input signal polarity used under RTS mode
(3-1) POSI --------------------Positive polarity (rising edge detection)
(3-2) NEGA-------------------Negative polarity (falling edge detection)
(7-1-4) RTS (Random Trigger Shutter) exposure selection
Switches light exposure mode under RTS mode
(4-1) FIX mode--------------- Bottom DIP SW Exposure-time control via bottom-panel DIP switch.
(4-2) PULSE W mode -------TRIG signal pulse width control Exposure-time control via TRIG signal
pulse width.
<Exposure time delay under RTS>
When the RTS is active, both in FIX mode and PULSE W mode, there is a time delay of
approximately 1.4 micro s until the start of exposure after the rising edge of TRIG signal (positive).
<Exposure time under pulse width mode>
Under RTS pulse mode, the exposure time is determined by the pulse width. More exactly, the actual
time is the pulse width plus approximately 19.1 micro s.
