Projector and method of controlling the same

Abstract

A projector adapted to perform a keystone distortion correction for correcting keystone distortion of an image projected on a projection surface, includes: a fluctuation detection section adapted to start detection of fluctuation state of the projector in response to a predetermined instruction signal; an angle detection section adapted to detect an installation angle of the projector; a distortion correction section adapted to perform the keystone distortion correction, in response to detection of a fluctuation settled state by the fluctuation detection section, in accordance with the installation angle detected by the angle detection section; and a control section adapted to terminate the detection of the fluctuation state by the fluctuation detection section in response to elapse of second time while keeping the fluctuation settled state from completion of the keystone distortion correction by the distortion correction section.
