Video monitoring system
First Claim
1. A video monitoring system comprising a video transmission apparatus and a video reception apparatus,the video transmission apparatus including at least one program which causes the video transmission apparatus to perform functions comprising:
- receiving a plurality of consecutive images obtained by imaging a monitoring area, the plurality of consecutive images being input to the video transmission apparatus;
detecting a target object to be monitored from the plurality of consecutive images;
tracking the target object detected by the detecting to obtain an existence time from an appearance to a disappearance of the target object in the monitoring area;
selecting an image, in which the target object is detected, from the plurality of consecutive images and reducing a data volume of the selected image to generate a data volume reduced image of the target object; and
transmitting the data volume reduced image to the video reception apparatus,the video reception apparatus including at least one program which causes the video reception apparatus to perform functions comprising;
receiving the data volume reduced image transmitted from the video transmission apparatus;
analyzing the data volume reduced image; and
transmitting a video request that requests a plurality of consecutive images of the target object to the video transmission apparatus based on an input made according to an analysis result of the analyzing,the video transmission apparatus further performing functions comprising;
storing the plurality of consecutive images input to the video transmission apparatus;
receiving the video request transmitted from the video reception apparatus;
generating a monitoring video of the target object including a plurality of consecutive images from the appearance to the disappearance of the target object based on the existence time of the target object when the the video request is received; and
transmitting the monitoring video to the video reception apparatus.

Abstract
A video transmission apparatus detects a target object to be monitored from images obtained by imaging a monitoring area, tracks the detected target object, obtains existence time from appearance to disappearance of the target object, and transmits a data volume reduced image of the target object to a video reception apparatus. The video reception apparatus analyzes the data volume reduced image transmitted from the video transmission apparatus and transmits a video request of the target object to the video transmission apparatus) based on input made according to the result of the analysis. When the video request transmitted from the video reception apparatus is received, the video transmission apparatus generates a monitoring video from the appearance to the disappearance of the target object based on the existence time of the target object and transmits the monitoring video to the video reception apparatus.
