OPTICAL POSITION DETECTION SYSTEM, CONTROL APPARATUS, POSITION DETECTION APPARATUS, CONTROL PROGRAM, AND DISTANCE MEASURING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2015/137050
Kind Code:
A1
Abstract:
Disclosed is an optical position detection system, wherein a position detection unit detects the position of a subject to be detected, said position being detected on the basis of electrical signals obtained by receiving, by means of a light receiving surface, light which has been radiated from the irradiation unit, and is reflected by means of the subject. A determining unit determines whether there is the subject or not on the basis of detection results obtained from the position detection unit. An operation control unit controls operation mode of the optical position detection system. The optical position detection system has: first operation mode, in which a lighting unit radiates light with a first light quantity; and second operation mode, in which the lighting unit radiates light with a second light quantity that is smaller than the first light quantity. In the cases where the determining unit determines that there is the subject, the operation control unit sets the operation mode to the first operation mode, and in the cases where the determining unit determines that there is no subject, the operation control unit sets the operation mode to the second operation mode.
