<P>PROBLEM TO BE SOLVED: To provide an optical position detection device and an optical position detection method for performing proper correction according to change of environmental temperature even without adding a temperature sensor, etc. <P>SOLUTION: In an optical position detection device 10 and an optical position detection method, a correction condition determination part 64 determines a correction condition based on a comparison result between a first coordinate value and a second coordinate value of default two-dimensional coordinate data detected by a position detection part 50 with a default state that a target object Ob does not exist, and when the two-dimensional coordinate data of the target object Ob is detected by the position detection part 50, correction corresponding to the correction condition is performed. Consequently, since temperature correction can be performed even without directly measuring environmental temperature, even when emission intensity of detection light from a light source 12 for detection changes due to the environmental temperature, the two-dimensional coordinate data of the target object Ob can be accurately detected. <P>COPYRIGHT: (C)2012,JPO&INPIT |
