Exposure Setting
The Exposure Setting can be found under this path:
Camera> Exposure
.
The exposure is the amount of light received by the image sensor and is
determined by the width of lens diaphragm opening, the amount of exposure by
the sensor (shutter speed) and other exposure parameters. With this item, users
can define how the Auto Exposure function works.
Each exposure mode is specified as follows:
Auto Mode
Auto Iris (Fixed Focal Lens Excluded)
In this mode, the exposure gives priority to the auto iris. The minimum
shutter speed can be set from 1 (1/1.5) to 1/30 (1/25) sec. AGC (Auto
Gain Control) will function automatically according to the light conditions
of the subject.
NOTE:
This function is not available for Fixed Focal Lens
Models.
Auto Shutter Mode
This function is to control the shutter speed and adjust the iris
automatically according to the light intensity. It is also effective if a fixed
iris lens is being used. The minimum shutter speed range is configurable
from 1 (1/1.5) to 1/500 (1/425) sec.
Shutter Priority Mode
This function is to set the shutter speed at a specified speed. The range
is configurable from 1/30 (1/25) to 1/500 (1/425) sec.
