Title:
HUMAN BODY DETECTOR
Document Type and Number:
Japanese Patent JP2003006758
Kind Code:
A
Abstract:
To provide a human body detector which makes erroneous detection less probable, thereby eliminating troublesomeness, etc., due to erroneous warning thereafter.
A prescribed threshold is provided previously to the value of a moving quantity for deciding movement. Thus, only when a detected value by a moving quantity arithmetic means exceeds the threshold, the presence of the movement of a human body is decided. By obtaining this threshold in line with the movement of a person by an experiment, etc., it is possible to decide a movement different from a movement made by a mere shadow. By judging the presence/absence of the movement by this moving quantity arithmetic means, it is possible to recognize the movement of a person reliably.
