Low Luminance Side Exposure Control (Mode) - Watec WAT-233 User Manual

3.3.1.3 Low Luminance Side Exposure Control (MODE)

Set the exposure control at low luminance side (MODE). The exposure control operate with gain or slow shutter at low light condition
when the image can not be exposed by electronic shutter or auto iris lens.

Exposure control at low luminance does not operate.
Automatic exposure control with gain at low luminance. Dynamic resolution is maintained though
noise is conspicuous in dark subjects. While switching the AGC HI / LO setting, the maximum value
of the gain can be switched. For details, refer to "3.3.1.4 Auto Gain Control (AGC HI/LO)".
Automatic exposure control with slow shutter at low luminance. You can capture the subject clearly
though dynamic resolution decreases in dark subjects.
The slow shutter operates in the range of 2-16 FLD.
Automatic exposure control with Gain and slow shutter at low luminance. Gain control the exposure
when the camera judge the luminance as low luminance. After Gain reaches to the maximum value,
Slow shutter operates for further sensitivity improvement. While swithing the AGC HI/LO setting, you can
switch the maxmum value of the gain. For details, refer to "3.3.1.4 Auto Gain Control (AGC HI/LO)".
The slow shutter operates in the range of 2-16 FLD.
Automatic exposure contril with slow shutter and Gain at low luminance. Slow shutter control the exposure
When the camera judges the luminance as low luminance. After the accumulation time of the slow shutter
has reached the maximum, gain control operates for further sensitivity improvement.
While swithing the AGC HI/LO setting, you can switch the maxmum value of the gain. For details, refer t to
"3.3.1.4 Auto Gain Control (AGC HI/LO)". The slow shutter operates in the range of 2-16 FLD.
