MONITORING CAMERA AND MONITORING CAMERA CONTROL METHOD
First Claim
1. A monitoring camera comprising:
- an imaging unit having a zoom lens;
a turn table that moves the imaging unit in panning and tilting directions;
an image processing unit which subjects an image captured by the imaging unit to image processing for identifying a tracking target, and generates tracking information including information about motion of the tracking target and pan, tilt and zoom information;
a tracking unit which tracks the tracking target by controlling the zoom lens of the imaging unit in accordance with the zoom information generated by the image processing unit and controls the turn table in accordance with the pan and tilt information generated by the image processing unit; and
an intrusion detection unit which determines, based on the information about motion of the tracking target generated by the image processing unit, whether or not the tracking target has intruded inside of a preset area from outside during tracking the tracking target, and outputs an alarm only when the tracking target has intruded the inside of the area from the outside.

Abstract
An image signal processing DSP subjects an image captured by an imaging element having a zoom lens to image processing for identifying a tracking target. In accordance with zoom information generated by the image signal processing DSP, the main CPU controls the zoom lens; and controls a turn table that moves the imaging element in panning and tilting directions in accordance with pan and tilt information, to track the tracking target. During tracking of the tracking, a determination is made, from information about movements of the tracking target generated by the image signal processing DSP, as to whether or not the target to be tacked has intruded the inside of the area from the outside. In a case where the target has intruded the inside of a preset area from the outside, an alarm command is produced when the target continually remains in the area for; e.g., one second.

5. A monitoring camera control method comprising:
-
subjecting an image captured by an imaging unit having a zoom lens to image processing for identifying a tracking target, and generating tracking information including information about motion of the tracking target and pan, tilt, and zoom information; tracking the tracking target by controlling the zoom lens of the imaging unit in accordance with the zoom information generated in the image processing step and controlling the turn table, which moves the imaging unit to panning and tilting directions, in accordance with the pan and tilt information generated in the image processing step; and determining, from the information about motion of the tracking target generated in the image processing step, whether or not the tracking target has intruded inside of a preset area from outside, during the course of tracking the tracking target, and that outputs an alarm only when the tracking target has intruded the inside of the area from the outside.
