Troubleshooting
Symptom
The pictures are too
light or too dark
The subjects appear
distorted
When the flash is fired
during shooting, only
the top or bottom of
the screen becomes
lighter
The brightness
changes cyclically or
the colours change,
and horizontal stripes
can be seen passing
across the screen
When fine lines or
cyclical patterns are
shot, flickering is seen
or colouring is added
to them
Cause and remedial action
p p Either select the auto setting for the iris or select the manual
setting and adjust the iris manually.
p p The pictures may be dark if the video signal cables are too long
because this will cause signal attenuation.
p p If a subject has suddenly crossed in front of the camera, it may
appear slightly distorted because this camera uses a MOS image
sensor.
This is normal and not indicative of any problem.
p p With a MOS image sensor, the shooting timing differs slightly
between the top left and bottom right of the screen. This means
that when the flash is fired, the bottom of the screen will become
lighter in the field concerned and the top will become lighter in
the next field.
This is normal and not indicative of any problem.
p p These phenomena (flicker) may occur under the illumination
produced by fluorescent lighting, mercury bulbs or other types of
discharge tubes.
This is normal and not indicative of any problem.
At a time like this, it is recommended that the electronic shutter
speed be set to 1/120 in areas with a 60 Hz power line frequency
or to OFF in areas with a 50 Hz power line frequency.
p p This phenomenon occurs because the pixels are arranged
systematically on each image sensor. It is noticeable when the
spatial frequency of a subject and the pixel pitch are brought into
proximity so change the camera angle or take other such action.
