First Claim
Patent Images
1. An intruder monitoring apparatus comprising:
- a monitoring camera for monitoring an object;
an image processor for analyzing an image from said monitoring camera;
a video device controller for controlling video devices including said monitoring camera;
means for managing at least one kind of information selected from a group of video device control information used for controlling the video devices, object characteristic quantity information which is information concerning characteristic quantities of the object, and a topographic information of an area to be monitored;
means for teaching said image processor characteristic quantities of an object; and
means for correcting the characteristic quantities, on the basis of which image analysis is effected, when any change occurs in conditions of the video devices and environments.

Abstract
An intruder monitoring apparatus has at least a feature of correcting characteristic quantities by which an object to be monitored is specified, on the basis reference characteristic, when any change occurs in conditions of the video devices and environments. A further feature is provided which a plurality of scenes are monitored periodically by one camera and an image analysis function is driven so as to monitor any intruder only when the camera unit is fixedly directed to a specific scene among the scenes.
