Display method and display system

Abstract

A projector includes a first acquisition unit, a detection unit, a second acquisition unit, and a display control unit. The first acquisition unit acquires a captured image of a range containing a display surface by a camera. The detection unit detects a first bright point and a second bright point corresponding to reflected lights of a first light and a second light radiated substantially parallel to the display surface by a pointer from the captured image. When a distance between a position of the first bright point and a position of the second bright point is less than a first threshold, the second acquisition unit acquires a third position determined based on the first bright point and the second bright point. The display control unit displays a display image containing a drawn image by the pointer in the third position.
