Abstract
A projector can include a projection section that projects an image on a projection surface, a detection light radiation section that radiates detection light in a direction corresponding to the projection surface. The projector can also include an adjuster that adjusts the direction of the detection light relative to the projection surface, and an imager and a controller that can detect reflected light resulting from the detection light to detect operation performed on the projection surface. The controller can evaluate whether or not the detection state of the reflected light corresponds to a specific state. If the detection is in the specific state, the adjuster can adjust the direction of the detection light based on a result of the evaluation.
