<P>PROBLEM TO BE SOLVED: To provide a detection method for motion not only capable of reducing using sensors to simplify a computing method but also capable of avoiding an effect easy to be affected by an environment, an electric noise, a difference between the sensors and the like, in an original sensed data, and capable of enhancing noise resistant ability of a motion detector. <P>SOLUTION: The sensed data are received from a referring reference sensor of a motion detecting module and a plurality of matched sensors, and a motion direction, a moving frequency and a motion speed are found using definition domain transformation and mathematical discriminants (discriminants for the direction, moving frequency and motion speed). <P>COPYRIGHT: (C)2006,JPO&NCIPI |
