5.1.1. LENS submenu
This submenu allows for setting the lens parameters. Because of used lens, settings in this
submenu don’t affect on displaying screen. Please let it in default option - MANUAL .
5.1.2. SHUTTER/AGC submenu
This menu offers how to control/select SHUTTER and AGC to get the best image for the high
luminance and the low luminance according to the scene.
In AUTO mode:
HIGH LUMINANCE Settings on the medium - and high-brightness side.
MODE (SHUT) Specifies AE control - Shutter. Not editable.
BRIGHTNESS (0-255) Sets brightness level.
LOW LUMINANCE Settings on the low-brightness side.
MODE (OFF/AGC) allows to switch Auto Gain Control to compensate the video level when
the scene is dim.
BRIGHTNESS Sets the brightness level which starts AGC from (x0.25/0.5/0.75/1.0) of full video
level. If set to x0.50, the camera will start AGC when the video level goes down below
the 50% level.
In MANUAL mode:
MODE (SHUT+AGC) defines available parameters for Manual Exposure mode,
SHUTTER (1/100000s - 1/50s) Sets the manual shutter. Manual shutter is only useful when
luminance is unchanged.
AGC (6.00-44.80) Sets AGC gain in dB. Higher gain make a scene brighter, but noise
increases.
5.1.3. WHITE BAL submenu
This submenu allows to choose appropriate settings depending on various colour temperature
conditions. White balance can be set to 7 modes listed below.
ATW (Auto Tracking White balance) is continuously monitoring/analyzing the colour
temperature of the incoming light and correcting the white balance. ATW limits the
colour temperature range at about 2,500˚K~8,500˚K to reduce the excessive
compensation for the big object which has a single colour.
SPEED Sets the AWB compensating speed. Lower value makes AWB faster. Too fast
an AWB may force colour oscillation.
DELAY CNT Adjusts the period between updates of AWB. The smaller value will
update AWB more frequently (faster).
