14 Working with images
14.1 Saving an image
14.1.1 General
You can save images to a memory card.
The camera saves an image file including all thermal and visual information. This means that you can open an image file at
a later stage and, for example, select another image mode, apply color alarms, and add measurement tools.
The image jpg file is fully radiometric and saved lossless, which enables full post-processing in FLIR Tools. There is also a regular jpg part (lossy) for convenient viewing in non-FLIR Systems software (Explorer).
14.1.2 About UltraMax
UltraMax is an image enhancement feature that increases the image resolution and lowers the noise, making small objects easier to
see and measure. An UltraMax image is twice as wide and high as an ordinary image.
When an UltraMax image is captured by the camera, several ordinary images are saved in the same file. Capturing all the images can take up
to 1 second. To fully utilize UltraMax, the images need to be slightly different, which can be accomplished by a slight movement of the camera. You should hold
the camera firmly in your hands (do not put it on a tripod), which will make these images vary just a little during the
capture. Correct focus, a high-contrast scene, and a non-moving target are other conditions that help to achieve a good-quality
UltraMax image.
At the moment, only FLIR Tools has the ability to process UltraMax images. Other FLIR software will treat the image as a regular image.
14.1.3 Image capacity
The capacity of a 4 GB memory card is theoretically 13 000 images (with no annotations).

- To return to the image archive overview, push the Back button .
Do one or more of the following:
Follow this procedure:
14.4 Editing a saved image
14.4.1 General
You can edit a saved image. You can also edit an image in preview mode.
14.4.2 Procedure
Follow this procedure:
Open the image in the image archive.
Push the joystick and select 
(Edit) from the menu.
Manual image adjust mode is now active, and the status icon is displayed. For image adjustment instructions, see 14.5 Adjusting an infrared image.
Push the joystick. This displays a context menu.
- Select
(Cancel) to exit edit mode. - Select
(Measurement parameters) to change the global parameters. - Select
(Image mode) to change the image mode. - Select
(Measurement) to add a measurement tool. - Select
(Color) to change the color palette or set a color alarm. - Select
(Save) to save and exit edit mode.
14.5 Adjusting an infrared image
14.5.1 General
An infrared image can be adjusted automatically or manually. When manual image adjust mode is active, the status icon is displayed.
is displayed.
- In live mode, push the button
to switch between automatic and manual image adjust modes. You can also switch between the modes by touching the temperature
scale on the screen. - In preview/edit mode, manual image adjust mode is active.
14.5.2 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 temperature scale to values close to the temperature of the building.

14.5.3 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 in the right image has been changed to values close to the temperature of the isolator.

14.5.4 Procedure
Follow this procedure:
In live mode, push the button to enter manual image adjust mode.
To change the temperature scale minimum and maximum limits simultaneously, move the joystick up/down.
To change the temperature scale minimum or maximum limit, do the following:
- Move the joystick left/right to select (highlight) the maximum or minimum temperature.
- Move the joystick up/down to change the value of the highlighted temperature.
(Optional step). In preview/edit mode, push the button to perform a one-shot auto-adjust sequence.
14.6 Performing a non-uniformity correction (NUC)
14.6.1 What is a non-uniformity correction?
A non-uniformity correction is an image correction carried out by the camera software to compensate for different sensitivities of detector elements and
other optical and geometrical disturbances1.
14.6.2 When to perform a non-uniformity correction?
The non-uniformity correction process should be carried out whenever the output image becomes spatially noisy. The output
can become spatially noisy when the ambient temperature changes (such as from day to night operation, and vice versa).
14.6.3 Procedure
To perform a non-uniformity correction, push and hold the Image archive button for more than 2 seconds.
