When the brightness (illuminance) level on the screen is set to a relatively low level with the [Brightness]
buttons, flickering may frequently happen.
•When the setting for “Light control mode” is “Indoor scene (50 Hz)”, “Indoor scene (60 Hz)” or “ELC”
whose maximum exposure time is 1/2000s or longer, brightness may not be remarkably changed even
when [Brightness] buttons are clicked.
•In such cases, either of the following can reduce flickering.
–Moderate the illumination intensities of objects by changing the camera direction.
–Set the brightness (illuminance) level on the screen to a brighter level with the [Brightness] buttons.
•When “On” is selected for “Wide dynamic range (WDR)”, only “Indoor scene (50 Hz)”, “Indoor scene
(60 Hz)” and “ELC(1/30s)” are available.
[AGC]
Select a method of gain adjustment from the following.
•On(High)/On(Mid)/On(Low): When the luminance of the subject becomes darker, gain will be
automatically incremented and screen will become brighter. “High”, “Mid” and “Low” are indications of gain
level.
•Off: Images will be captured with the fixed gain level.
•Default: On(High)
[Auto slow shutter]
The electronic sensitivity enhancement (sensitivity up) can be carried out by adjusting the storage time of the
sensor.
The following are available for the recording duration.
Off(1/30s), Max.2/30s, Max.4/30s, Max.6/30s, Max.10/30s, Max.16/30s
•Default: Off(1/30s)
IMPORTANT
•When “On” is selected for “Auto slow shutter”, frame rate may become lower. Noise or white dots
(blemishes) may sometimes appear.
Note
•When “Max. 16/30s” is selected, for example, sensitivity will automatically be increased up to x16.
When “Off” is selected for “AGC”, this setting is unavailable.
