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.
By using the
Auto adjustment region
feature it is possible to select an area of the image,
and then have the colorization of the image adjusted based on the temperatures within
that selected area. For more information, see section 11.3.2
In manual mode, you can adjust the temperature scale to values close to the temperature
of a specific object in the image. This will make it possible to detect anomalies and small-
er temperature differences in the part of the image of interest. In manual mode, the col-
ors are distributed evenly from the lowest to the highest temperature (linear color
distribution).
In manual mode, you can adjust the image by touching the screen or by using the naviga-
tion pad. For more information, see sections 11.3.3

Example 1
Here are two infrared images of a building. In the left image, which is auto-adjusted, the
large temperature span between the clear sky and the heated building makes a correct
analysis difficult. You can analyze the building in more detail if you change the tempera-
ture scale to values close to the temperature of the building.

Example 2
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.
