MONITORING CAMERA SYSTEM AND CONTROL METHOD OF MONITORING CAMERA SYSTEM
First Claim
1. A monitoring camera system, comprising:
- a first camera which captures an image at a first field angle; and
a second camera which is connected to the first camera to be capable of communicating with each other and captures an image at a variable second field angle,wherein the first camera notifies the second camera of movement information indicating a movement of an object in a monitoring target area twice at different timings in a specific monitoring target area set in the first field angle in advance,the second camera changes the second field angle to a field angle corresponding to the specific monitoring target area on the basis of the movement information which is first notified, andwhen a movement of the object is not detected in the specific monitoring target area, an image of the specific monitoring target area is captured at the second field angle after being changed on the basis of the movement information which is second notified.

Abstract
An image processing camera generates movement information on the basis of an omnidirectional image captured at a fixed field angle, and notifies PTZ camera of first movement information through a network. The PTZ camera analyzes the first movement information, changes a field angle to a specific monitoring target area. The image processing camera transmits second movement information to the PTZ camera. The PTZ camera analyzes the second movement information, captures a projected image of the specific monitoring target area when it is recognized that a current field angle is correct on the basis of the second movement information. Accordingly, an image of the specific monitoring target area is captured in a situation where there is no object such as a figure while monitoring a wide range.

13. A control method of a monitoring camera system including a first camera which captures an image at a first field angle, and a second camera which is connected to the first camera to be capable of communicating with each other and captures an image at a variable second field angle, the method comprising:
-
notifying the second camera of first movement information indicating a movement of an object in a monitoring target area in the monitoring target area which is set in the first field angle in advance by the first camera; changing the second field angle to a field angle corresponding to a specific monitoring target area on the basis of the movement information which is first notified by the second camera; notifying the second camera of second movement information indicating a movement of the object in the monitoring target area by the first camera; and capturing an image of the specific monitoring target area at the second field angle after being changed on the basis of the movement information which is second notified when a movement of the object is not detected in the specific monitoring target area by the second camera.
