PURPOSE: A change detecting method and a change detecting apparatus and a monitoring system using the method or apparatus are provided to transmit monitoring information to different destinations based on a detected position or a size of an object. CONSTITUTION: A change detecting apparatus includes an input image portion(1202), a region specification unit, a notification destination determination part(1207), a characteristics extraction part(1204), a characteristic extractor, a monitoring information generator(1206), and a transmitter(1209). The region specification unit specifies N regions, where N is a positive integer equal to or larger than 2, in a monitor image. The notification destination determination part specifies notification destinations of image changes in the monitor image in advance according to characteristics of the image changes. The characteristics extraction part detects an image change in the N regions. The characteristic extractor extracts at least one characteristic of the image changes. The monitoring information generator generates monitor information related to each of the detected image changes. The transmitter transmits the monitor information to a predetermined notification destination determined in the notification destination determination part based on the detected characteristic. |
