Zusammenfassung:	PROBLEM TO BE SOLVED: To reduce a memory capacity required to perform keystone correction on an image to be projected, in parallel by plural means.SOLUTION: An inclination sensor (121) detects inclination of a projection apparatus (100) with respect to a screen. An image division unit(132) divides image data on an image to be projected into divided image data of plural regions and supplies each piece of divided image data to image processing units (117 to 120). Each image processing unit (117 to 120) comprises: a memory for storing the divided image data from the image division unit (132); communication means which delivers and receives image data to and from another image processing unit and stores received image data in the memory; and keystone correction means for performing keystone correction of the image data in the memory, in accordance with the inclination of the projection apparatus.
