136
(1) Exposure Mode
Select from [Auto], [Manual], [Auto (Flickerless)] or
[Auto (Shutter-priority AE)].
If [Auto] is selected for [Day/Night] under [Camera] in
the Setting page (p. 43), select [Auto], [Auto
(Flickerless)] or [Auto (Shutter-priority AE)].
[Auto]
The exposure is controlled automatically.
[Manual]
The exposure is set by adjusting the shutter speed
and gain values manually.
[Auto (Flickerless)]
In this mode, video flickering caused by fluorescent
lights, etc., can be reduced. The shutter speed is
automatically adjusted according to the brightness
of the environment in which the camera is used.
[Auto (Shutter-priority AE)]
In this mode, the desired shutter speed can be
specified.
(2) [Exposure Compensation]
When [Auto], [Auto (Flickerless)] or [Auto (Shutter-
priority AE)] is selected for [Exposure], the exposure
compensation value desired can be selected from
nine levels (-4 to +4) using the slider.
To darken the video, select a negative value. To
brighten the video, select a positive value.
(3) [Metering Mode]
When [Auto], [Auto (Flickerless)] or [Auto (Shutter-
priority AE)] is selected for [Exposure], the metering
mode can be selected from [Center-Weighted],
[Average] or [Spot].
For an explanation on each item set in [Metering
Mode], see [Metering Mode] in the Setting page
(p. 42).
(4) [Shutter Speed]
When [Manual] or [Auto (Shutter-priority AE)] is
selected for [Exposure], select the shutter speed
desired. If [Manual] is selected, set the shutter speed
in the range of [1/1 sec] to [1/16000 sec] from a pull-
down menu. If [Auto (Shutter-priority AE)] is selected,
set the shutter speed in the range of [1/2 sec] to [1/
16000 sec] from a pull-down menu.
When capturing a moving subject, selecting a higher
shutter speed can reduce blurry video capture.
(5) [Slow Shutter]
You can set slow shutter if [Exposure] is set to [Auto]
or [Auto (Flickerless)]. Select a value in the range of
[1/2 sec] to [1/30 sec] from the pull-down menu.
As slower shutter speeds generate afterimages when
capturing a moving subject, select an appropriate
time according to the capture conditions.
(6) [Gain]
If [Manual] is selected for [Exposure], set a desired
gain value.
Moving the slider to the left decreases the gain
(sensitivity to brightness) and darkens the video.
Moving the slider to the right increases the gain and
brightens the video.
„ Setting White Balance
(1) [Auto]
The white balance is adjusted automatically.
(2) [Light Source]
Select the light source from the pull-down menu below
according to the condition in which the camera is
used.
For an explanation on each item set in [Light Source],
see [White Balance] in the Setting page (p. 43).
(3) [Manual]
The white balance is adjusted manually.
[One-shot WB]
This is used for forcibly locking the white balance to
match the light source.
Important
• If the subject is a traffic signal or electronic scoreboard, etc.,
the captured video may flicker.
In this case, try changing [Exposure] to [Auto (Shutter-priority
AE)] and then select a shutter speed lower than 1/100, to see
if the situation improves.
• [Exposure Compensation] and [Manual] for [Exposure]
cannot be selected if [Smart Shade Control] is set to [Auto].
• The [BLC] button is not available if [Exposure] is set to
[Manual].
• Even if [Exposure] is set to [Auto (Flickerless)], some screen
flicker may still occur under unstable light source conditions.
• When [Camera] > [Camera Control] > [AGC Limit] is set to
[OFF] and [Exposure] is set to [Auto (Shutter-priority AE)],
exposure compensation and backlight compensation will not
be performed.
