Abstract:
A projector adapted to perform display by projecting an image on a projection surface, includes: a light source; a light modulator adapted to modulate light from the light source into image light representing the image; a projection optical system adapted to project the image light modulated by the light modulator on the projection surface; a keystone distortion correction section adapted to perform a keystone distortion correction process for correcting keystone distortion of the image to be projected on the projection surface; a detection section adapted to detect start of movement of the projector; and a control section adapted to cancel the keystone distortion correction process in the keystone distortion correction section in response to detection of start of movement of the projector in the detection section.
