Abstract

A coordinate detection system detects coordinates of a position to which an electronic pen points on a surface of a display. The coordinate detection system includes a plurality of detecting elements configured to detect light emitted from each of light emission points of the electronic pen, and a coordinate detection unit configured to detect the coordinates of the position to which the electronic pen points based on a distance relationship between first images of the light emission points in an image formed by the light detected by each of the plurality of detecting elements and second images of the light emission points formed by reflection of the first images on the surface of the display.
