<P>PROBLEM TO BE SOLVED: To provide a position detecting system properly imaging an image of an object and improving the position detection precision of the object, by imaging an image of a frequency band of infrared light; a display system; and an information processing system. <P>SOLUTION: A position detecting system 400 includes an imaging portion 500 for imaging a picked-up image, and a coordinate computing portion 430 for obtaining the coordinate information of an object in a detection area set on an object surface, on the basis of the picked-up image from the imaging portion 500. To the detection area, irradiation light of a frequency band of infrared light is emitted. The imaging portion 500 images an infrared light band image which is an image of the frequency band of the infrared light as a picked up image, and the coordinate computing portion 430 obtains the coordination information of the object on the basis of the infrared light band image. <P>COPYRIGHT: (C)2012,JPO&INPIT |
