Abstract: A projector includes a main body including a projection unit which projects an image, a movement detecting unit which detects movement of the main body, and an imaging unit which captures an image of a screen. Furthermore, the projector includes a correction control unit which performs trapezoidal distortion correction on the basis of an image-capturing result, and a second processing unit which performs a second process, which is different from the trapezoidal distortion correction, on the basis of the image-capturing result. In a case where it is determined that the main body is moving on the basis of a detection result, an imaging control unit allows the correction control unit to perform the trapezoidal distortion correction, and in a case where it is determined that the main body is stopped, the imaging control unit allows a manipulation detecting unit to perform a manipulation detecting process.

Abstract: A projector includes a manipulation detecting unit that performs a manipulation detecting process on the basis of captured image data of an imaging unit, and a correction control unit that performs a distortion correcting process on the basis of the captured image data. An imaging control unit sets an image-capturing resolution of the imaging unit to resolutions different from each other between a case where the manipulation detecting unit performs the manipulation detection process and a case where the correction control unit performs the distortion correcting process.
