FFC Mode
The internal of the thermal imaging camera may
comprise the mechanical action correction
mechanism that can periodically improve the
image quality. This component is called flat field
correction (FFC). When controlling the FFC, the
FFC shields the sensor array, so that each portion
of the sensor can collect uniform temperature
fields (flat field). By means of FFC, the camera
can update the correction coefficients to output
more uniform images. Throughout the FFC
process, the video image is frozen for two seconds
and a static-frame image is displayed. After the
FFC is complete, the image is automatically
recovered. Repeated FFC operations can prevent
the grainy and image degradation problems. The
FFC is especially important when the temperature
of the camera changes. For example, after the
camera is powered on or the ambient temperature
is changed, you should immediately perform the
FFC.
Auto
: In the Automatic FFC mode, the camera
performs FFC whenever its temperature changes
by a specified amount or at the end of a specified
period of time (whichever comes first). When this
mode is selected, the FFC interval (minutes)
