Monitoring camera system, monitoring camera control device and monitoring program recorded in recording medium
First Claim
1. A monitoring system comprising:
- a plurality of cameras each of which monitors a monitor area and has a changeable imaging magnification;
monitoring section which detects an object to be monitored in the monitor area; and
control section configured to control said plurality of cameras in a supervisory manner, and which, in response to the detection of the object to be monitored, selects at least one camera capable of obtaining an enlarged image to contribute to identification of the object to be monitored as camera for enlargement from the plural cameras and selects at least one camera other than the camera for enlargement as camera for wide area from the plural monitoring camera, said control section setting the camera for wide area to a first imaging magnification to obtain a wide area image of the monitor area, and setting the camera for enlargement to a second imaging magnification larger than the first imaging magnification to obtain an enlarged image of the detected object to be monitored.

Abstract
A monitoring system according to the present invention has a plurality of cameras respectively monitoring a monitor area and having a changeable imaging magnification, monitoring section detecting an object to be monitored in the monitor area, and control section selecting at least one camera capable of obtaining an enlarged image to contribute to identification of the object to be monitored as camera for enlargement from the plural cameras when the object to be monitored is detected and selecting at least one camera other than the camera for enlargement as camera for wide area from the plural monitoring camera. The camera for wide area is set to a first imaging magnification to obtain a wide area image of the monitor area and the camera for enlargement is set to a second imaging magnification larger than the first imaging magnification to obtain an enlarged image of the detected object to be monitored.

15. A monitoring system comprising:
-
a plurality of cameras, each camera having a variable imaging magnification capability and being adapted to monitor a monitor area; and a control device configured to operate with said plurality of cameras, said control device including; a monitor section which is adapted to detect an object to be monitored in the monitor area based on data received from at least one of said plurality of cameras; and a control section which is configured to control two or more of said plurality of cameras in a supervisory manner, said control section being configured so that, in response to the detection of the object being monitored, said control section selects at least one camera, from said plurality of cameras, as a camera for enlargement for obtaining an enlarged image to contribute to identification of the object to be monitored, said control section being further configured so that, in response to the detection of the object being monitored, said control section selects another one of said plurality of cameras as a camera for wide area to obtain a wide area image of the monitor area, a magnification of said camera for enlargement being larger than a magnification of said camera for wide area.
