Abstract
A projector has a projection optical system including a projection lens and a processing device. The processing device makes the projection optical system project a correction image having a rectangular shape. The number of correction points arranged on a first side out of two sides connecting to a vertex located the farthest from the projection lens when projected on a projection surface out of four vertexes of the correction image is larger than the number of correction points arranged on a side different from the two sides. The processing device receives an operation of moving first correction point included in the correction points arranged on the first side, and makes the projection optical system project an output image obtained by applying a distortion correction based on the operation to an input image.
