Abstract
Disclosed herein is a method of correcting the distortion of an image overlap area. The method includes identifying an overlap area between images projected by a plurality of projectors, obtaining information about the brightness of an image projected on the overlap area, and controlling the brightness of the image projected on the overlap area. Controlling the brightness of the image includes incorporating a transparency variable α into the image, and the transparency variable of an image projected by a specific projector is reduced toward remaining boundaries of the overlap area at a boundary of a non-overlap area and the overlap area.
