Exposure Setting - LevelOne FCS-5051 User Manual

5.5.1 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.
