ABSTRACT:
A projector has an acceleration sensor for detecting a tilt angle of the projector, a manual controller for manually setting a correction amount for a keystone distortion correction, an auto/manual switch, an upper edge basis corrector for determining parameters for an upper edge basis keystone distortion correction, a lower edge basis corrector for determining parameters for a lower edge basis keystone distortion correction, and an image processor for performing a keystone distortion correction on the image on the basis of the upper edge or lower edge in accordance with parameters applied thereto from the upper edge basis corrector or lower edge basis corrector to display the corrected image on a liquid crystal panel or the like. As the auto/manual switch selects an automatic adjustment, the acceleration sensor and upper edge basis corrector are connected to the image processor. As a manual adjustment is selected, the manual controller and lower edge basis corrector are connected to the image processor.
