A projector that can solve a problem in which a projection image is disturbed due to deviation of incident positions of projection light to a screen is provided. Projection section 11 includes LD light emission section 111 and scanning section 112 that scans light emitted by LD light emission section 111 and projects the scanned light to the rear plane side of the screen. Control section 12 controls an amount of light emission of the light and a scanning angle of scanning section 112 based on an image signal so as to cause projection section 11 to project an image corresponding to the image signal to the screen. Control section 12 corrects an orientation of projection light corresponding to each pixel of the image projected from projection section 11 based on a refractive index of the light transmission member and a scanning angle of scanning section 112 so as to correct an incident position of the projection light on the screen.
A projector that projects light to a rear plane side of a screen having a screen support member composed of a light transmission member located on the rear plane of the screen, comprising:
An image correcting method using a projector that has a projection section including a light source and a scanning section that scans light emitted by said light source and projects the scanned light to a rear plane side of a screen having a screen support member composed of a light transmission member located on the rear plane of the screen, comprising:
