MANUAL
In this focus mode, users can adjust the focus speed, ranging from 0 ~ 3.
3.3.5 AE
MODE
The exposure is the amount of light received by the image sensor and is
determined by the width of lens diaphragm opening (iris adjustment), the
amount of exposure by the sensor (shutter speed) and other exposure
parameters. With this item, users can define how the Auto Exposure (AE)
function works.
E/F/U Model:
•
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.
BRIGHT
The brightness control function adjusts IRIS and AGC using an internal
algorithm. Brightness is controlled by gain when the light condition is dark
and by iris when the light condition is bright. The bright value ranges from
00 ~ 31.
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.
IRIS
With this option, 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 opening of a
lens controls the amount of light reaching to the surface of the selected
FOCUS SPEED
