First Claim
Patent Images
1. An image capturing device, comprising:
- an electronic image sensor;
a memory including a frame buffer storing at least one digital image frame; and
a processor, said processor communicating with said electronic image sensor and said memory, said processor conducting an image capture of a digital image frame into said frame buffer and extracting predetermined events in said digital image frame by comparing said digital image frame with a stored quiescent image frame.

16. An event monitoring method, comprising the steps of:
-
capturing a quiescent frame at a beginning of an event monitoring session;
capturing a digital image frame;
comparing said digital image frame to said quiescent frame;
determining if said digital image frame is substantially different from said quiescent frame; and
if said image frame is substantially different from said quiescent frame, identifying an event by comparing said difference with a stored plurality of predefined events. - View Dependent Claims (17, 18, 19)
