
MANUAL
Select this item if you want to adjust aperture value manually. Higher value enhances the
incident ray of camera.
AE MODE
The exposure is the amount of light received by the image sensor and is determined by how
wide you open the lens diaphragm (iris adjustment), by how long you keep the sensor exposed
(shutter speed), and other exposure parameters. With this item, users can define how the Auto
Exposure (AE) function works.

AUTO
In this mode, the camera ’s Shutter, IRIS and AGC control function work automatically to
compensate the light exposure of image sensor for consistent video output level. IRIS OFF
SET is used to set the level of IRIS variation.

SHUTTER
With this option, the SHUTTER priority is higher than IRIS and AGC; IRIS and AGC circuit will
function automatically in cooperating with SHUTTER to get consistent exposure.

IRIS
With this option, the IRIS priority is higher than SHUTTER and AGC; SHUTTER and AGC
circuit will function automatically in cooperating with IRIS to get consistent exposure. If the IRIS
is modified manually, the action of exposure compensation depends on the AGC circuit.

AGC
With this option, the AGC priority is higher than SHUTTER and IRIS; SHUTTER and IRIS
circuit will function automatically in cooperating with AGC to get consistent exposure. If AGC is
adjusted manually, the exposure compensation depends on the changing of IRIS.
WBC MODE
A digital camera needs to find reference colour temperature, which is a way of measuring the
quality of a light source, for calculating all the other colours. The unit for measuring this ratio is in
