A projector includes a projection unit, an imaging unit, a correction control unit acquiring first correction information based on a first captured image acquired by capturing a distortion detection image projected onto a projection surface, and a distortion correction unit performing distortion correction based on the first correction information. The correction control unit, in a case where second distortion correction needs to be performed after the distortion correction unit, performs first distortion correction based on the first correction information, allows the projection unit to project the distortion detection image without transforming the distortion detection image by using the distortion correction unit allows the imaging unit to capture the projected distortion detection image so as to be acquired as a second captured image, acquires second correction information based on the second captured image, and allows the distortion correction unit to perform the second distortion correction based on the second correction information.
