<P>PROBLEM TO BE SOLVED: To provide a video signal processing device etc. having a simple configuration, capable of displaying real time a video image having suppressed distortion of video light to be visually recognized by an observer. <P>SOLUTION: The video signal processing device includes: a screen 1 having a projection surface of optional shape; a distortion correction unit 3 for distortion correcting a plane video signal, originally prepared to project the video light on a planar projection surface, so as to output to project the video light on a projection surface of optional shape; a parameter adjustment PC 5 for generating a distortion correction table, which is a corresponding map of the planar projection surface to a mesh model of the projection surface of optional shape; and projectors 2a, 2b for projecting each video image on the screen based on the video signal output from the video signal processing device. The distortion correction unit 3 inputs the distortion correction table from the parameter adjustment PC 5, and by referring to the distortion correction table, performs distortion correction processing on a pixel-by-pixel basis of the planar video signal which is input by a video signal input means, and generates the video signal to project the video light on the projection surface of optional shape. <P>COPYRIGHT: (C)2011,JPO&INPIT |
