Claim 0:
1. An obstacle detection system of a movable barrier operator, the obstacle detection system comprising:
a light emitter configured to emit a light signal across an opening;
a camera having a field of view adjacent the opening and configured to monitor a zone of interest within the field of view, the zone of interest being associated with the light signal;
a processor operatively coupled to the camera and configured to determine whether the opening is obstructed based at least in part on whether the camera detects an object in the zone of interest, wherein the light signal includes a geometric characteristic associated therewith, and the field of view of the camera is narrowed based at least in part on the geometric characteristic associated with the light signal; and
communication circuitry operatively coupled to the processor, the processor being further configured to cause the communication circuitry to transmit an obstruction signal to the movable barrier operator in response to the camera detecting the object in the zone of interest.
