5.3.5. 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 ranges from -10.5dB to 10.5dB. Select <OFF> to disable this 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, the Shutter speed takes main control of exposure. Bright Value, Iris and AGC will function
automatically in cooperation with the shutter speed to achieve a consistent exposure output. The range of shutter
speed starts from 1/10000 to 1/25 at PAL systems (NTSC: 1/10000 to 1/30).
- IRIS:
With this option selected the iris of the lens will control the exposure. Bright Value, Shutter Speed and AGC
circuit will function automatically in cooperation with the Iris to get consistent exposure output. The opening of a
lens controls the amount of light reaching to the surface of the selected device. By increasing the F-stop number
(F1.6, F2, F2.4, etc.), less light is permitted to pass. The option range is from F1.6 to F28.
- MANUAL:
In this mode, users can adjust the Shutter Speed (NTSC: 1/10000 ~ 1/30, PAL:1/10000 ~ 1/25), the Iris Value (F1.6
~ F28) and the Gain Value (-3dB ~ 28dB).
EXIT & SAVE:
Exit the AE FUNCTION menu and go back to the Main Page 1 to set the WBC mode.
