Abstract:
A method for passive optical motion detection uses an optical sensor arrangement comprising an optical sensor having at least one signal channel. The optical sensor arrangement is initialized for repeated signal acquisition and an initial frame comprising a tuple of sensor data is collected from the at least one signal channel. The initial frame is set as a previous frame. A loop of motion detection is entered and the following steps are repeated. First, a current frame comprising another tuple of sensor data is collected from the at least one signal channel. Then, a motion parameter is computed from a motion metric depending on the current and previous frames. The so computed motion parameter is compared with a threshold value. A motion event parameter is set depending on the comparison of the motion parameter with the threshold value. The current frame is set as previous frame so that the loop can start all over again.

Claim (Index 3):
The method according to  claim 1 , wherein the motion metric comprises taking an absolute difference of the tuples of current and previous frames.
