FLIR Tags

FLIR Tags

Information extracted from the maker notes of JPEG images from thermal imaging cameras by FLIR Systems Inc.

Tag ID Tag Name Writable Values / Notes
0x0001 ImageTemperatureMax rational64u (these temperatures may be in Celsius, Kelvin or Fahrenheit, but there is no way to tell which)
0x0002 ImageTemperatureMin rational64u  
0x0003 Emissivity rational64u  
0x0004 UnknownTemperature? rational64u  
0x0005 CameraTemperatureRangeMax? rational64u  
0x0006 CameraTemperatureRangeMin? rational64u  

Information extracted from FLIR FFF images and the APP1 FLIR segment of JPEG images. These tags may also be extracted from the first frame of an FLIR SEQ file.

The thermal image data may be stored either as raw data, or in PNG format. If stored as raw data, ExifTool adds a TIFF header to allow the data to be viewed as a TIFF image. If stored in PNG format, the PNG image is extracted as-is. Note that most FLIR cameras using the PNG format seem to write the 16-bit raw image data in the wrong byte order.
