MEMO
• When the shutter speed is slower than 1/7.5 s, the following
phenomena may occur.
1)
The screen update rate becomes longer in the case of digital output.
2)
The displayed image will appear intermittently in the case of analog output.
3)
Time will be required for the auto white, auto iris and ALC operations.
If the shutter speed is set slower than 1 s, these operations will
behave as follows.
Auto white : Auto white balance function cannot be started.
( ੬ page E23 White balance adjustment)
Auto iris : Stops at the iris value at that time.
ALC : Stops at the sensitivity at that time.
To use a shutter speed slower than 1 s, use with the following settings selected:
IRIS MODE : MANUAL
GAIN : STEP or V.GAIN
•
There may be shortage of light when the shutter speed is increased. In
this case, adjust the iris or sensitivity. Attention should be paid to the pic-
ture quality when the sensitivity is raised since the image becomes coarse.
