Abstract
A change in position or direction of a projector may be detected by a simple configuration. A projector includes a light projection unit that projects an image, a projection unit main body that houses the light projection unit, and a power supply housing part that supports the projection unit main body. Further, the projector includes an imaging part provided in either of the power supply housing part or projection unit main body, and a control unit that detects a relative position or relative direction between the projection unit main body and the power supply housing part based on a captured image of the imaging part.
