Patent ID: 8113666

Claim:
A projector comprising: a light source; a light modulator that modulates the light flux emitted from the light source in accordance with an image signal to form image light; a projection optical apparatus that enlarges and projects the image light; a reflection section having a reflection surface disposed along the direction in which the projection optical apparatus outputs the image light, the reflection surface reflecting the image light; an adjustment section that adjusts the inclination angle of the reflection section with respect to the direction in which the image light travels; a first inclination angle detector that detects the inclination angle of the reflection section with respect to the direction in which the image light travels; an acquisition section that acquires the image signal to be outputted to the light modulator; a distortion corrector that corrects the image signal not to distort the projected image based on the inclination angle detected by the first inclination angle detector; an image signal output section that outputs the image signal corrected by the distortion corrector to the light modulator; and a second inclination angle detector that detects the inclination angle of the projector with respect to the horizontal plane, wherein the distortion corrector corrects the image signal based on the inclination angle detected by the second inclination angle detector.
