Saving and working with images

8.1 About image files

8.1.1 General

When you save an image, the camera saves an image file that includes all thermal and
visual information. This means that you can open an image file at a later time and, for ex-
ample, 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-proc-
essing in image analysis and reporting software from FLIR Systems. There is also a reg-
ular *.jpg component (lossy) for convenient viewing in non-FLIR Systems software (e.g.,
Microsoft Explorer).
Note
• The camera can also be configured to save an extra low-resolution visual image as a
separate file. This can be convenient if you are not using a post-processing software.
Select (Settings) > Save options & storage > Photo as separate JPEG = On.
• When the Digital camera image mode is selected, a high-resolution digital image is
stored when an image is saved. However, no thermal information is stored. For more
information, see section 11 Working with image modes.
• You can choose to turn off the digital camera. This can, for example, be required in re-
stricted areas and in confidential (e.g., doctor/patient) situations. Select
> Save options & storage > Digital camera = Off. When the digital camera is off, fea-
tures that require visual information, such as the images modes Thermal MSX and
Picture in picture, are disabled.

8.1.2 File-naming convention

The default naming convention for image files is FLIRxxxx.jpg, where xxxx is a unique
counter.
It is also possible to save images with a date prefix added to the filename. However,
these files may not automatically be detected by third-party applications. For more infor-
mation, see the setting File naming format in section 22.4 Save options & storage.

8.1.3 Storage capacity

When you save an image, the camera stores the image file on the memory card.
The size of an image file (with no annotations) is typically less than 1000 kB. Thus, the
capacity of a 8 GB memory card is approximately 8000 images.
Note Empty or use a memory card that has not previously been used in another type of
camera. The cameras may organize files differently on the memory card. There is there-
fore a risk of losing data if the same memory card is used in different types of cameras.

8.1.4 About UltraMax

Note The availability of this feature is dependent on the camera model.
UltraMax is an image enhancement feature that increases the image resolution and low-
ers 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
within the same file. Capturing all the images can take up to 1 second. To fully utilize Ul-
traMax, the images need to be slightly different, which can be accomplished by a minute
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 fo-
cus, a high-contrast scene, and a non-moving target are other conditions that help to
achieve a good-quality UltraMax image.
