Abstract:
1. An optical touch panel apparatus, comprising: a flat panel which is rectangular in shape; an optical path generation unit, which includes a plurality of light emitting elements arranged along each of adjacent two sides of the flat panel and a plurality of light receiving elements arranged along sides respectively opposed to the two sides, for generating a plurality of optical paths on the flat panel by receiving light emitted from one light emitting element of the plurality of light emitting elements at a plurality of light receiving elements opposite to the one light emitting element; a detection unit for detecting a position at which any one of the plurality of optical paths is blocked on the flat panel; a setting unit for setting a band-like peripheral area on the flat panel as an area where the resolution for detection of the position is lower than a specific resolution for detection of the position in an area excluding the band-like peripheral area; and an area limitation unit for limiting an area for which detection of the position is to be performed among areas on the flat panel to the area excluding the band-like peripheral area set by the setting unit for which no detection of the position is to be performed.
