1. Lighting Compensation
This function uses software to perform lighting compensation for every camera. The standard
is that when the lighting range is established as 60mA and the intensity is 128 at all adjusted
zones, the gray level of the gray card image is compensated to 100.
1. Press [S

]. Key in “regedit” to open the registry. Enter
“HKEY_LOCAL_MACHINE\HKEY_LOCAL_MACHINE\SOFTWARE\TRI\” and check if
there is a DWORD variable named “LightingCompensation”. If the variable does not exist,
open the main program of TR7500 and the variable is created automatically.
2. To execute lighting compensation, change the value of the variable to “1”.
3. The first time the lighting is executed, the system creates the following four parameters:
[Central/Gray] – the objective gray level for the four side-view cameras -- and
[CentralGrayRGB0], [CentralGrayRGB1], and [CentralGrayRGB2] -- the objective gray
level for R, G, B sensors.

compensation. (Note: Be sure that the FOVs of 5 cameras are on the gray card.)
2. Lighting Decay Auto Check
This function uses software to test the difference between the current value (before
compensating) and the objective value for all five cameras.

4. For the first time, the system displays the window below to ask if you want to save the
position of the gray card to system. The value of the X-coordinate and Y-coordinate are
saved in the registry and named “GrayCardPosX” and “GrayCardPosY”. When the two
variables exist, the window below does not appear again. To change the value, move the
cameras to be on the gray card then click on the [Teach Position] button.
