Event detection in a video recording system
First Claim
1. A system for visually monitoring a scene and detecting an event occurring within the scene comprising:
- visual means for visually monitoring the scene and for providing a video signal representative of an image of the scene;
sensing means sensing changes within the scene and providing a signal indicative thereof; and
, processing means processing the respective signals from the visual means and the sensing means to determine if any activity occurring within the scene comprises an event, the processing means producing a signal indicative of each event occurrence.

Abstract
A video recording system (10) monitoring a scene to detect occurrence of an event within the scene. A camera (C1) monitors the scene and provides a video signal representative of the scene. A sensor (C2) senses movement within a portion of the observed scene and provides a signal indicative of the movement. A processor (12) connected to the camera and sensor determines if there is any movement within the scene; and if there is, the portion of the scene where it occurred based upon the signals received from the camera and sensor. The processor produces a signal indicative of the event and the portion of the scene where it occurs. A digital video recorder (18) connected to the processor now records the scene and the signal indicative of the occurrence of the event.

16. A video system for monitoring a scene to detect an event occurring within the scene comprising:
-
first imaging means continually viewing the scene and producing a signal representative of an image of the scene;
second imaging means continually viewing a portion of the scene and producing a signal representative of an image of the portion of the scene;
processor means processing signals from the first and second imaging means to determine if an event occurs within the scene as evidenced by the simultaneous occurrence of changes within the scene and the portion of the scene, the processor means producing a signal indicative of such changes if an event occurs; and
,output means responsive to the processing means for generating a signal representative of the occurrence of each event. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 28, 29, 30, 31, 32, 33, 34, 36, 37, 38, 39, 40, 41, 42, 43)

27. A method for visually monitoring a scene to detect occurrence of an event within the scene comprising:
-
visually monitoring the scene and providing a video signal representative of an image of the scene;
sensing a change within a portion of the scene and providing a second signal indicative of the change;
determining if any change within the scene and the portion thereof, based upon the signals, represents the occurrence of an event within the scene; and
,producing a third signal indicative of the event if it is determined that an event has occurred within the scene.

35. A method for visually monitoring a scene for detecting the occurrence of an event within the scene comprising of:
-
visually monitoring the scene with a first imaging means and providing a first video signal representative of the scene;
visually monitoring the scene with a second imaging means and providing a second video signal representative of the scene;
determining the simultaneous occurrence of changes within the scene and the portion of the scene viewed by each imaging means and producing a third signal indicative of each event occurring within the scene and the portion of the scene.
