Parameter Note
AGC It is to set the image auto gain, ranging from 0
～
255.
AGC Max Gain
It is to the image max gain, ranging from 0
～
255. The bigger the value is, the
bigger the image contrastness becomes, but with bigger noise.
AGC Plateau It is to set the image AGC Plateau, ranging from 0
～
255.
Gain Mode
It can select three modes: low temperature, high temperature and auto, it is low
temperature by default. Under auto mode, it can set threshold of switching low to
high temperature, low temperature area percentage, threshold of switching high to
low temperature, high temperature area percentage.

In low temperature mode, when the temperature exceeds
“
threshold of
switching low temperature to high temperature
”
, and the pixel that
temperature exceeds the threshold is greater than
“
low temperature area
percentage, then it will switch to high temperature mode.

In high temperature mode, when temperature is lower than
“
the threshold of
switching high temperature to low temperature
”
, and the pixel that
temperature is lower than threshold is greater than
“
high temperature area
percentage
”
, then it will auto switch low temperature mode.

Set rule: the temperature threshold of switching low to high temperature needs
to be higher than that of switching high to low temperature, the sum of two
area percentage needs to be bigger than 100.
FFC Mode
Auto: it means that the thermal shutter is regularly corrected according to the
switch cycle which is set by users.
FFC Switch
Cycle
It means how much time it takes to implement shutter correction for once, it is valid
only when FFC mode is auto.
Shutter
Correction
Click it to trigger shutter correction for once.
Note:
Click
“Default” to restore “camera condition” back to initial state.
6.1.1.3 Profile Management
There are three types of profile management which are
“Normal”, “Full Time” and “Schedule”.
Step 1
Select
“Setup > Camera > Conditions > Profile Management” and the system will display the interface of
“Profile Management”, which is shown in Figure 6-10.
