Document Type and Number:
Japanese Patent JP4796104
Kind Code:
B2
Abstract:
A touch position detection device (10) is provided in proximity of image capture sensors (12) and includes at least one external light sensor (15) having a lower light detection sensitivity than the image capture sensors (12) and an external light intensity calculation section (3) for calculating an external light intensity which is the intensity of light in the surroundings of a pointing member according to the quantity of light received by the external light sensor (15). Therefore, the external light intensity in the surroundings of the pointing member with which to point at an image capture screen containing the image capture sensors can be accurately calculated.
