Monitoring system and imaging system

Claim 2

A monitoring system comprising: an imaging device for imaging a monitoring area; means for detecting information corresponding to amount of movement of an object in the monitoring area on the basis of an output of the imaging device; means for judging whether or not a person to be monitored exits from the monitoring area on the basis of the information relating to the movement of the object; and reporting means for reporting, when it is judged that the person to be monitored exits from the monitoring area, to a supervisor that the person to be monitored exits from the monitoring area.

Claim 3

A monitoring system comprising: a recording device; first imaging means for imaging a whole monitoring area; second imaging means for taking a close-up of a part of the monitoring area and imaging the part whose close-up has been taken, the second imaging means being imaging means other than the first imaging means and having an automatic focusing function; a switch for switching between an output of the first imaging means and an output of the second imaging means and feeding the output obtained by the switching to the recording device; a pan tilt driving device for moving the second imaging means upward, downward, rightward and leftward; detection means for detecting an amount of movement of an object in the monitoring area on the basis of an output of the first imaging means; first control means for controlling the switch such that the output of the first imaging means is fed to the recording device when the movement of the object in the monitoring area is not detected by the detection means; and second control means for controlling the pan tilt driving device, when the movement of the object in the monitoring area is detected by the detection means, wherein the pan tilt driving device directs the second imaging means at the moving object in the monitoring area, thereby to make the second imaging means take a close-up of the moving object and image the object, the second control means further for controlling the switch such that the output of the second imaging means is fed to the recording device.

Claim 4

A monitoring system comprising: a recording device; first imaging means for imaging a whole monitoring area; second imaging means for taking a close-up of a part of the monitoring area and imaging the part whose close-up has been taken, the second imaging means being imaging means other than the first imaging means and having an automatic focusing function; a switch for switching between an output of the first imaging means and an output of the second imaging means and feeding the output obtained by the switching to the recording device; a pan tilt driving device for moving the second imaging means upward, downward, rightward and leftward; detection means for detecting an amount of movement of an object in the monitoring area on the basis of an output of the first imaging means; first control means for controlling the switch such that the output of the first imaging means is fed to the recording device when the movement of the object in the monitoring area is not detected by the detection means; and second control means for controlling the pan tilt driving device, when the movement of the object in the monitoring area is detected by the detection means, wherein the pan tilt driving device directs the second imaging means at the moving object in the monitoring area, thereby to make the second imaging means take a close-up of the moving object and image the object, the second control means further for controlling the switch such that the output of the second imaging means is fed to the recording device.
