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, Shutter Speed takes main control of exposure, and both IRIS and AGC will function automatically
in cooperation with the shutter speed to achieve consistent exposure output. The shutter speed ranges from
1/10000 to 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 the IRIS to get consistent exposure output. The IRIS value is fixed at f1.6.
- Manual:
In this mode, users can adjust the shutter speed (1/10000 ~ 1/50 for PAL; 1/10000 ~ 1/60 for NTSC) and the gain
value (-3dB ~ 28dB) for optimised video output.
EXIT:
Exit the AE MODE menu and go back to the Main Page 1 to set the WBC mode.
5.3.6. WBC MODE
A digital camera needs to find a reference colour temperature, which is a way of measuring the colour of a light
source, for calculating all the other colours. The unit for measuring this ratio is in degree Kelvin (K). You can
select one of the White Balance Control modes according to the installation condition.
