AE Mode
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 by other exposure parameters. With this item, users can define how the Auto
Exposure (AE) function works.
EXPOSURE COMPENSATION
The exposure value rages from -10.5dB ~ 10.5dB. Select <OFF> to disable the function.
AE MODE
AUTO
In this mode, the camera's Brightness, Shutter Speed, IRIS and AGC (Auto Gain
Control) control circuits work together automatically to get consistent video output
level.
SHUTTER
With this option, Shutter Speed takes main control of exposure, and both IRIS and AGC
will function automatically in cooperation with shutter speed to achieve consistent
exposure output. The shutter speed ranges from 1/10000 ~ 1/50.
IRIS
In this mode, the IRIS function adjusts exposure in higher property. SHUTTER speed
and AGC circuit will function automatically in cooperating with IRIS to get consistent
exposure output. The IRIS value is fixed at f1.6.
Manual
In the mode, users can adjust shutter speed (1/10000 ~ 1/50 for PAL; 1/10000 ~ 1/60
for NTSC) and gain value (-3dB ~ 28dB) for optimized video output.
