The Subtract or Compare mode has two selectable output modes. One provides the difference plus 0.5. The other provides the absolute value of the difference. Additionally, a button is provided to invert the output thereby showing the reference minus the input instead of the input minus the reference. A "Difference Threshold" control allows adjustment of the unit's sensitivity to differences.
An additional operational mode allows subtraction of each video frame from the previous frame to provide "frog's eye" capability, displaying only motion in the scene being monitored by the input video camera.
