Abstract:
1. A projector comprising: a laser beam generation portion outputting a laser beam; an image projection portion, including a scanning portion scanning said laser beam, projecting an image on a projection area; an image correction portion correcting distortion of projected said image on the basis of projection condition information; a photoreceiving portion receiving said laser beam reflected by a detection object; and a position acquisition portion acquiring the position of said detection object on the basis of photoreceiving information of said laser beam received by said photoreceiving portion and said projection condition information employed by said image correction portion for correcting said image; and wherein said image correction portion is configured to estimate a scanning locus of said laser beam on said projection area on the basis of said projection condition information and to correct said distortion of said projected image on the basis of estimated said scanning locus; and wherein said position acquisition portion is configured to estimate a scanning locus of said laser beam on said projection area on the basis of said projection condition information and to acquire the position of said detection object on the basis of estimated said scanning locus and said photoreceiving information.
