Coordinate detection method, coordinate detection program, and coordinate detection system

摘要

A coordinate detection system includes a camera configured to capture an image of a face opposite to a display face of a transmissive display panel including a plurality of luminous parts and to thereby produce video information, and a video processor configured to detect coordinates instructed on the display face of the transmissive display panel based on the luminance or chromaticity of reflected light, which occurs when reflecting light emitted from each luminous part of the transmissive display panel, according to the captured video information.
