Change detecting method and apparatus and monitoring system using the method or apparatus
First Claim
1. A change detecting apparatus comprising:
- an input unit that receives a monitor image picked up by a pickup unit;
a region specification unit that specifies N regions (N is a positive integer equal to or larger than
2) in the monitor image;
a notification destination specification unit that specifies notification destinations of image changes in the monitor image in advance according to characteristics or features of the image changes;
a change detection unit that detects an image change in the N regions;
a characteristics extraction unit that extracts at least one characteristic or feature of the image changes from said change detection unit;
a monitor information generation unit that generates monitor information related to each of the detected image changes; and
a transmission unit that transmits the monitor information,wherein said transmission unit transmits the monitor information to a predetermined notification destination, which is set in said notification destination specification unit, based on the detected characteristics or features of the image change.

Abstract
A change detecting apparatus and monitoring system using the apparatus as a notification apparatus. The change detecting apparatus has an input unit receiving a monitor image captured by a pickup unit, a region specification unit specifying N regions (N≧2) in the monitor image, a notification destination specification unit specifying notification destinations of image changes in the monitor image in advance according to the image change characteristics, a change detection unit detecting an image change in the N regions, a characteristics extraction unit extracting a feature of the image change, a monitor information generation unit generating monitor information related to the detected image change and a transmission unit transmitting the monitor information. Based on the detected image change characteristics, the monitor information is transmitted to a notification destination set in the notification destination specification unit.

12. A change detecting method comprising the steps of:
-
setting N monitor regions (N is an integer equal to or larger than
2) in a pickup range of a camera in advance;creating, in advance, a notification destination table in which notification destinations of image changes in an image from the camera are set according to characteristics of the image changes; reading an image from an image accumulation unit, in which images from said camera are accumulated, detecting an image change in the image that has been read; extracting characteristics or features of the detected image change; creating monitor information related to the detected image change; and transmitting the monitor information to a predetermined notification destination based on the extracted characteristics features. - View Dependent Claims (13, 14, 15, 16, 17, 18)
