Operation Manual
102
• It is recommended that you check that the camera is focused whenever you reboot the camera.
• The estimated focus ranges depending on the [Day/Night] setting are shown in the following table.
* Using infrared illumination from an external device may throw the camera out of focus.
You can use [Camera] > [Day/Night Mode Focus] > [Compensate for light source] to focus according to the wavelength of an infrared
light (P. 107).
[One-shot AF]
Use when [Focus] is set to [Manual]. When you click [Exec], the camera will focus once using autofocus and then switch to
manual.
[Adjust Focus]
If the [Focus] is set to [Manual], you can click and hold the [Near] and [Far] buttons to adjust the focus in the near and far
directions.
[Exposure]
Selects an exposure mode.
Note
If [Auto] is selected in [Day/Night], select either [Auto], [Auto (Flickerless)], [Auto (Flickerless2)] ( ), [Auto
(Shutter-priority AE)] or [Auto (Aperture-priority AE)] ( ) for [Exposure].
[Auto]
Automatically controls the exposure.
[Auto (Flickerless)]
Automatically adjusts the shutter speed according to the brightness of the usage environment. Video flickering caused
by fluorescent lights, etc., is reduced.
[Auto (Flickerless2)]
Use this mode if you cannot achieve the desired flickering reduction even after selecting [Auto (Flickerless)]. However,
the appropriate exposure level may not be applied (causing excessive brightness) because the range of automatic
shutter speed adjustment cannot exceed 1/100 seconds while using this mode.
[Auto (Shutter-priority AE)]
Automatically adjusts the aperture and gain according to the specified [Shutter Speed].
[Auto (Aperture-priority AE)]
Automatically adjusts the gain and shutter speed according to the specified [Aperture].
[Manual]
Manually set [Shutter Speed], [Aperture] ( ), and [Gain].
Cannot be set when [Smart Shade Control] is set to [Auto].
[AGC Limit]
Select the Auto Gain Control (AGC) limit value for increasing gain to brighten video in low light conditions.
The greater the value, the higher the sensitivity will become, but video noise will increase.
