<P>PROBLEM TO BE SOLVED: To provide a projector capable of projecting in normal shape on a corner where three wall surfaces intersect almost perpendicularly without carrying out advanced and complicated processing. <P>SOLUTION: The projector comprises a first compression means M1 correcting image data so that compressibility to the approximate center in the lateral direction of the image data linearly rises upward from below; a second compression means M2 correcting the image data by compressing the image data vertically by a predetermined amount while fixing the lower end of the image data; and a third compression means M3 correcting the image data so that compressibility in the vertical direction linearly rises from the approximate center in the lateral direction to the lateral side while fixing the upper end and the approximate center of the lower end of the image. <P>COPYRIGHT: (C)2009,JPO&INPIT |
