Mode], see [Metering Mode] in the Setting page
(p. 53).
(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) [Aperture]
If [Manual] is selected for [Exposure], set a desired
aperture value.
Moving the slider to the left closes the aperture and
darkens the image. Moving the slider to the right
opens the aperture and brightens the image.
(7) [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 image.
Moving the slider to the right increases the gain and
brightens the image.
Important
• If the subject is a traffic signal or electronic scoreboard, etc.,
the captured image 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].
• When [Camera] > [Camera Control] > [AGC Limit] is set to
[OFF] in the setting page and [Exposure] is set to [Auto
(Shutter-priority AE)], exposure compensation and backlight
compensation will not be performed.

[R Gain], [B Gain]
When setting the white balance manually, set the
values of red and blue gain in the range 0 to 1023 to

achieved depending on the applicable light source. In this
case, use the [One-shot WB] function.
