A visual image sensor system for detecting an abnormal change in a monitored scene is disclosed, wherein normal changes which may occur in the monitored scene are previously memorized to be selectively compared with changes in the monitored scene, whereby the normal changes are discriminated from the actual abnormal change to be detected. An alarm is issued when the monitored scene includes a change different from any of the memorized normal changes selected according to one or more rational selection standards, whereby false or redundant alarms due to the normal changes are prevented. For further precise detection, abnormal changes which may occur in the monitored scene are also previously memorized to be compared with the changes in the monitored scene.
