Changing image mode

7.13.1

General

The camera can operate in five different image modes:

•

Thermal MSX

(Multi Spectral Dynamic Imaging): The camera displays an infrared im-

age where the edges of the objects are enhanced.

•

Thermal

: The camera displays a fully thermal image.

•

Picture-in-picture

: The camera displays a digital camera image with a superimposed

infrared image frame.

•

Thermal blending

: The camera displays a blended image that uses a mix of infrared

pixels and digital photo pixels. The mixing level can be adjusted.
