12.1
General
An infrared image can be adjusted automatically or manually.
In automatic mode, the camera continuously adjusts the level and span for the best im-
age presentation. The colors are distributed based on the thermal content of the image
(histogram color distribution). The temperature scale to the right of the screen shows the
upper and lower temperatures of the current span.
In manual mode, you can adjust the temperature scale to values close to the temperature
of a specific object in the image. This mode lets you center on the temperatures around
the background of the gas, to make the gas appear more clearly. When measuring tem-
peratures, manual mode will make it possible to detect anomalies and smaller tempera-
ture differences in the part of the image of interest. In manual mode, the colors are
distributed evenly from the lowest to the highest temperature (linear color distribution).
You can adjust the image manually by touching the screen or by using the navigation
pad. For more information, see sections 12.3

Manual adjustment by using the navigation pad
• In live mode, touch the soft button
to switch between automatic and manual image
adjustment modes.
• In preview/edit mode, manual image adjustment mode is active.
Note

Switch between auto and manual
: Allows you to switch between automatic and man-
ual image adjustment modes.
•
Auto adjust the manual temperature scale
: Allows you to perform an automatic adjust-
ment of the image while remaining in manual image adjustment mode.
Note
Adjustment of the temperature scale is not possible in
HSM
mode.

Example
Here are two infrared images of an isolator in a power line. To make it easier to analyze
the temperature variations in the isolator, the temperature scale in the right image has
been changed to values close to the temperature of the isolator.
