Achieving good focus
Adjusting the focus is required to clearly image of
the target. For the auto focus type, focus can be
adjusted easily in the Auto Focus Adjustment. For
the manual focus type, the focus can be adjusted
while conrming the image and focus indicator.
“Focus Adjustment” (Page 4-12)

If good focus cannot be achieved by
the Auto Focus Adjustment
The focusing position may not be adjusted
correctly if the image is too dark or too bright.
Adjust to the applicable brightness with Auto
Brightness Adjustment (Page 4-11) and then
perform the auto focus adjustment.
If the focus still cannot be adjusted with the auto
focus adjustment for the auto focus type, adjust
the focus manually.
“When the focusing position is to be
adjusted manually” (Page 4-13)
Adjust the focus position by tapping the [+] or [-]
button.
Reducing the image blur
If the image is blurred by imaging a moving
target, the image blurring can be corrected by
shortening the exposure time (shutter time). Adjust
the exposure time with the advanced brightness
adjustment.
“Advanced Brightness Adjustment” (Page 4-18)
Exposure time

Bright
When the value of brightness is reduced, the
exposure time becomes shorter resulting in a
less blurry image.

Imaging Mode
Select [HighGain] in the imaging mode so that
the brightness gain becomes higher. The screen
becomes brighter so that the exposure time can
be shortened and the image blurring can be
reduced. The image noise may increase.
Also, the exposure time may be shortened if the
[HDR] is selected in the imaging mode.
By unmounting the dome attachment or polarizing
lter attachment, image blurring can be lessened
as the exposure time can be shortened.
