ALIBRATION

The SMX-12A2x camera software allows you to calibrate colors using a color rendition 
chart. You can create calibration files for different light conditions and then apply them 
depending on camera location.

Calibration Procedure

Before calibration, prepare the following:

1

Install an IR-cut filter and lens on the camera.

2

Put a color rendition chart in front of the camera.

Note:

Without an IR-cut filter, color calibration will not perform correctly.

To calibrate colors:

1

Start video from the camera.

2

Disable auto white balance, otherwise calibration will not perform correctly:

a.   

Press 

Alt+s

 to open the 

Settings

 dialog box.

b.   

Click the 

Advanced

 tab.

c.   

Go to the 

White Balance

 section and press 

Disable

.

3

Set the maximum viewport size (

Settings

 > 

General

 > 

Viewport

).

4

Adjust focus and image like it is shown below. Decrease zoom so that the image fits 
the application window:
