Motion detecting web camera system

Abstract

A camera system that includes a video camera and a processor, which periodically uploads images captured by the video camera to a web server in accordance with one of a plurality of motion detection algorithms. A first motion detection algorithm captures a current image frame when a pixel comparison between successive image frames exceeds a predetermined threshold.

1 . A camera system for connection to a web server comprising: 
 a video camera; and    a processor that periodically uploads images captured by the video camera in accordance with a plurality of motion detection algorithms, a first motion detection algorithm capturing a current image frame when a pixel comparison between successive image frames exceeds a predetermined threshold and a second motion detection algorithm capturing a stable frame after a certain duration has lapsed since the predetermined threshold has been exceeded.    
   
   
       2 . The camera system of  claim 1  wherein the processor uploads the current image frame at programmed intervals.  
   
   
       3 . (Cancelled)  
   
   
       4 . The camera system of  claim 1  wherein the plurality of motion detection algorithms further comprises a third motion detection algorithm that captures a recent motion frame that occurs a predetermined time period prior to the occurrence of a stable frame, the stable frame occurring after a certain duration has elapsed since the predetermined threshold has been exceeded.  
   
   
       5 . (Cancelled)  
   
   
       6 . The camera system of  claim 4  wherein the processor includes a circular buffer to successively store motion captured in image frames in which the predetermined threshold is exceeded.
