Abstract
A method for controlling a projector includes projecting a projection image representing a first mark and a second mark on a projection surface, generating captured image data representing a captured image by causing the imaging section to capture an image of the projection image displayed on the projection surface, and detecting the position of the first mark and the position of the second mark based on the captured image data. The first mark and the second mark are so located in the captured image that a first distance between the first mark displayed on the projection surface and the imaging section is longer than a second distance between the second mark displayed on the projection surface and the imaging section. The size of the first mark is greater than the size of the second mark in the captured image.
