Abstract: A projection apparatus includes a matrix expression generation unit which generates viewpoint correction matrices used for a conversion calculation on each of the projection surfaces for an image to be projected, a mask generation unit which generates correction mask data indicating regions corresponding to the viewpoint correction matrices generated by the matrix expression generation unit for the image, and a projection control unit which executes the conversion calculation on the image using each viewpoint correction matrix generated for each corresponding region in the correction mask data generated by the mask generation unit, and thereafter controls the projection unit to project the image.
