Monitoring camera and monitoring camera control method
First Claim
1. A system for tracking a moving subject, comprising:
- a camera that captures an image of an imaging area within a monitoring area, the imaging area being determined in accordance with an initial imaging direction of the camera; and
a processor that sets a preset area within the monitoring area,whereinwhen the moving subject intrudes into the preset area, the processor changes the imaging direction from the initial imaging direction to a second imaging direction toward the preset area and tracks the moving subject by moving the camera in a tilt direction or in a pan direction.

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 target, 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 tracked 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.

4. The system for tracking a moving subject according to the claim 1, wherein
the processor changes the imaging direction by moving the camera in the tilt direction or in the pan direction such that the moving subject is positioned in a center of the image captured by the camera. -
5. The system for tracking a moving subject according to the claim 1, further comprising
a camera apparatus that includes the camera, the processor and a receiver, wherein the processor sets the imaging direction of the camera to be toward the preset area by rotating the camera in the tilt direction or in the pan direction via the rotator when the receiver receives a signal transmitted from another apparatus different from the camera apparatus. -
6. The system for tracking a moving subject according to the claim 1, further comprising
a memory that stores location information indicating a position within the preset area, wherein the processor sets the imaging direction of the camera according to the location information to be toward the position within the preset area by moving the camera in the tilt direction or in the pan direction when the processor receives a predetermined input, the processor further rotates the camera for tracking the moving subject in the tilt direction or in the pan direction according to the location information. -
7. The system for tracking a moving subject according to the claim 1, wherein
the processor rotates the camera for tracking the moving subject in the tilt direction or in the pan direction when the moving subject intrudes an inside of the preset area from an outside of the preset area. -
8. The system for tracking a moving subject according to the claim 7, wherein
the processor does not rotate the camera for tracking the moving subject in the tilt direction or in the pan direction when a first position where the moving subject is detected within the preset area. -
9. The system for tracking a moving subject according to the claim 7, wherein
the processor rotates the camera for tracking the moving subject in the tilt direction or in the pan direction when the moving subject stops for a predetermined period. -
10. The system for tracking a moving subject according to the claim 1, wherein
the camera is configured to capture a plurality of images by rotating the camera, each of the captured plurality of images corresponding to each of partial areas of the monitoring area.
