Patent ID: 8382291

Claim:
A projector adapted to perform display by projecting an image on a projection surface, comprising: 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; a storage section adapted to store guide pattern data representing a guide pattern indicating a center of a maximum area capable of modulating the light from the light source in the light modulator; and a control section adapted to cancel the keystone distortion correction process in the keystone distortion correction section and make the light modulator modulate the image light representing the guide pattern based on the guide pattern data stored in the storage section in response to detection of the start of movement of the projector in the detection section.
