Abstract
A change detecting method and apparatus constituted by an input portion for inputting image data obtained by imaging apparatus, a processing unit for processing the image data inputted from the input portion, and a storage for storing the image data. The processing unit has an image data change detecting portion, a monitoring information generating/transmitting portion. The storage has a monitoring schedule table. The image data change detecting portion reads the image data from the storage based on the monitoring schedule table, and detects a change in image data from the image data. The monitoring information generating/transmitting portion generates monitoring information based on a result of the detected change and outputs the monitoring information.
