Title:
IMAGE PROCESSING UNIT FOR SUPERVISION
Document Type and Number:
Japanese Patent JPH09214938
Kind Code:
A
Abstract:

To correct undesirable detection internally before it is notified externally by providing a means discriminating occurrence of external disturbance when a change area appears at a prescribed area.

An external disturbance discrimination section 8 receives change area data from a change area extract section 5 to discriminate whether or not the change area is in existence in an external disturbance discrimination area. When the change area is in existence in the external disturbance discrimination area, it is discriminated that external disturbance takes place and informed to an alarm processing section 7A. The alarm processing section 7A restricts alarm processing when it receives a notice of presence of external disturbance and makes usual alarm processing when no external disturbance takes place. Thus, occurrence of undesired detection due to shadow of a building or the like is suppressed, and undesired detection is corrected internally before alarming without much loss in the processing speed so as to avoid undesirable alarming externally.
