OBJECT DETECTING APPARATUS AND METHOD, PROGRAM AND RECORDING MEDIUM USED THEREWITH, MONITORING SYSTEM AND METHOD, INFORMATION PROCESSING APPARATUS AND METHOD, AND RECORDING MEDIUM AND PROGRAM USED THEREWITH

摘要

An object detecting apparatus and method accurately detect an event while reducing power consumption. A photosensor is used to detect an object entering a monitoring region, and a microwave sensor is used to detect the object, which enters another monitoring region. State data representing the state of the object is generated based on detection information obtained by both sensors.
