Symptom Cause and solution Reference pages
1080/29.97PsF images appear jerky
• This is normal operation.
→ In the PsF (Progressive segmented Frame) format, an identical image is captured
to fields 1 and 2 in order to output the same image as progressive. Therefore, the
image will appear slightly jerky.

1080/25PsF images appear jerky
• This is normal operation.
→ In the PsF (Progressive segmented Frame) format, an identical image is captured
to fields 1 and 2 in order to output the same image as progressive. Therefore, the
image will appear slightly jerky.

Something is wrong with the
coloring of the pictures
• Activate the ATW (Auto tracking white adjustment) function. page 41
• In some situations, the proper colors may not be reproduced using the ATW
function.
→ In cases like this, proceed with the white balance adjustment.
pages 40 to 41
The pictures are too light or too dark
• Either select the auto setting for the iris or select the manual setting and adjust
the iris manually.
page 38
• The pictures may be dark if the analog video signal cables are too long because
this will cause signal attenuation.

Images are in black and white
• Is the unit in night mode?
→ In night mode, output will be in black and white.

Auto white balance adjustment
(AWB) is not possible
• Is the unit in night mode?
→ Auto white balance adjustment (AWB) is not possible in night mode.

The screen is too bright in night
mode
• The aperture is set to open in night mode to prevent video voyeurism. Adjust the
brightness at the light source.

The iris does not operate in night
mode
The subjects appear distorted
• Since this camera uses an MOS imaging device, the pickup timing differs slightly
at the top left and bottom right of the screen. This means that if a subject moves
quickly across the front of the camera, it may appear slightly distorted. This is
not a malfunction.

When the flash is fired during
shooting, only the top or bottom of
the screen becomes lighter
• With a MOS imaging sensor, the pickup timing differs slightly at 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.

The brightness changes cyclically
or the colors change, and horizontal
stripes can be seen passing across
the screen
• These phenomena (flicker) may occur under the illumination produced by
fluorescent lighting, mercury bulbs or other types of discharge tubes.
Try one of the following in this situation:
- Set [Flicker Suppression] in the MENU settings to [On].
- Set the electronic shutter speed to 1/100 in regions with a power supply frequency of
50 Hz, and turn the electronic shutter off in regions with a power supply frequency of
60 Hz.
page 49, page 113
When fine lines or cyclical patterns
are shot, flickering is seen or
coloring is added to them
• 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 action.

Noise occurs in the audio input
• The following causes are possible.
- The camera, switching hub, or peripheral devices are not grounded.
- Power lines are running nearby.
- Equipment generating strong electric or magnetic fields (e.g., television and radio
antennas, air conditioning motors, power transformers) are located nearby.
If the problem cannot be resolved via movement of surrounding devices, use a
microphone equipped with an amplifier, or connect an audio output with low output
impedance.
