5.1.5 Record
The “Record” button either captures a still image, or starts/stops live video
recording. See Section 7 for details on available file formats.
5.1.6 FFC (Recalibrate)
To maintain optimum performance, thermal imaging cameras must
occasionally perform an internal recalibration (also known as a Flat Field
Correction, or FFC). This is accomplished using an internal shutter, and takes
less than one second. During recalibration, a subtle audible “click” can be
heard, and live video is momentarily frozen. This function takes place
automatically (based on internal camera parameters), and can be manually
initiated through user command via the “Recalibrate” button on the home
screen, or through an appropriately-configured PWM channel.
Recalibrating prior to taking critical measurements will ensure the most
consistent image contrast.
