<p><P>PROBLEM TO BE SOLVED: To solve a problem of operation inconvenience of a conventional electrooptical mouse by a defect of sensitivity of the electrooptical mouse. <P>SOLUTION: In this double sensing light source-loaded electrooptical mouse and a sensing method therefor, a concept of a double sensing light source of a synchronous light source, and an asynchronous light source or the like is used, and both the light sources are combined by each angle to improve the sensing sensitivity and accuracy related to various kinds of surface environment (e.g. a coarse surface or a uniform surface). In the double sensing light source-loaded electrooptical mouse, manual and automatic changeover modes are provided, the necessary light source is made to be selected by a user end, and the necessary light source is changed over on the basis of a track pattern by sensing by the automatic changeover mode. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
