<P>PROBLEM TO BE SOLVED: To suppress image distortion occurring in displaying an image on a screen without correcting a distortion compensation table by a simple structure. <P>SOLUTION: This image signal processor includes: a distortion compensation table storage part 15a for storing a distortion compensation table being a corresponding map between a planar projection surface and a mesh model of a projection surface of an optional shape in order to project image light on the projection surface 1 of an optional shape for applying distortion compensation processing to a planar image signal input by an image signal input part 11; and a table compensation parameter storage part 15b for storing a table compensation parameter for compensating displacement between a reference pixel position of a planar image and a reference position in the distortion compensation table. A distortion compensation part 12 compensates the distortion compensation table using the table compensation parameter, and applies distortion compensation processing to each pixel of the planar image signal input by the image signal input part 11 by referring to the compensated distortion compensation table to generate an output image signal for projecting image light on the projection surface. <P>COPYRIGHT: (C)2010,JPO&INPIT |
