Troubleshooting
Symptom
Something is wrong
with the coloring of
the pictures
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 colors change,
and horizontal stripes
can be seen passing
across the screen
When fine lines or
cyclical patterns are
shot, flickering is seen
or coloring is added to
them

Cause and remedial action
p  Activate the ATW (Auto tracking white adjustment) function.
p  In some situations, the proper colors may not be reproduced
using the ATW function.
 In cases like this, proceed with the white balance adjustment.
p  Either select the auto setting for the iris or select the manual
setting and adjust the iris manually.
p  The pictures may be dark if the analog video signal cables are too
long because this will cause signal attenuation.
p  Since this camera uses an MOS image device, the shooting timing
differs slightly at the top left and bottom right of the screen.
This means that if a subject has moved quickly across in front of
the camera, it may appear slightly distorted.
This is normal and not indicative of any problem.
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  These phenomena (flicker) may occur under the illumination
produced by fluorescent lighting, mercury bulbs or other types of
discharge tubes.
In cases like this, it is recommended that the electronic shutter
speed be set to 1/100 in areas where the power line frequency is
50 Hz and that the electronic shutter be set to OFF in areas where
the power line frequency is 60 Hz.
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.
