PROJECTOR APPARATUS, PROJECTION METHOD, AND RECORDING MEDIUM STORING PROJECTION METHOD

A projector apparatus is disclosed which has a projection unit which projects image corresponding to an input image signal, an instruction unit which issues an instruction for performing keystone correction, a distance survey unit which surveys distances between the projector apparatus and a plurality of positions on the image projected by the projection unit in accordance with an instruction from the instruction unit, and a focus control unit which performs keystone correction of the image projected by the projection unit in a manner that the image becomes a rectangle having an appropriate aspect ratio based on the distances obtained by the distance survey unit, while bringing the image projected by the projection unit into focus at the center position of the image after being keystone-corrected.
