This is not available if [Smart Shade Control] (P. 159) is set to [Auto].
(3) [Metering Mode]
When you select [Auto], [Auto (Flickerless)] or [Auto (Shutter-priority AE)] for [Exposure], you can select the metering
mode.
[Center-Weighted]
The entire scene is metered with an emphasis on the center.
Even when slightly darker/brighter areas are present on the periphery of the scene, an appropriate exposure can be
achieved for the subject near the center.
Use this mode if the subject is positioned near the center of the screen.
[Average]
The entire scene is metered and averaged.
A stable exposure can be achieved even in a capture environment where there are notable brightness differences
within the screen.
Use this mode to stabilize the exposure in scenes where vehicles or people are moving.
[ S pot]
The center of the screen is metered.
An appropriate exposure can be achieved for the subject at the center of the screen regardless of the brightness/
darkness on the periphery of the screen.
Use this mode if you want to adjust the exposure to the center of the screen because the subject is, for example, lit by
a spotlight or backlit.
(4) [ S hutter S peed]
When you select [Manual] or [Auto (Shutter-priority AE)] for [Exposure], you can select the shutter speed.
If [Manual] is selected, set the shutter speed in the range of [1/1 sec] to [1/16000 sec].
If [Auto (Shutter-priority AE)] is selected, set the shutter speed in the range of [1/2 sec] to [1/16000 sec].
When capturing a moving subject, selecting a higher shutter speed can reduce blurry video capture.
Setting a slow shutter speed may prevent Intelligent Function from working correctly. Select a shutter speed that suits
the capture conditions and purpose.
(5) [ S low S hutter]
If you select [Auto] or [Auto (Flickerless)] for [Exposure], select the slowest shutter speed from the range [1/2 sec] to
[1/30 sec].
Slower shutter speeds generate afterimages in video when capturing a moving subject.
(6) [Aperture]
If [Manual] is selected for [Exposure], set a desired aperture.
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 the sensitivity to affect brightness.
Moving the slider to the left darkens the video, moving it to the right brightens video.
Important
• If a traffic signal, electronic scoreboard, etc. is captured the 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 please refer to if the situation improves.
• Setting a slow shutter speed may prevent Intelligent Function from working correctly. Select a shutter speed that suits the capture
conditions and purpose.
