    摘要： A virtual reality creating system including: a screen 1 including a projection plane of arbitrary shape; a distortion correction unit 3 which performs distortion correction for projecting image light onto the projection plane of arbitrary shape for a two-dimensional image signal to project image light onto a two-dimensional projection plane and then outputs the same; a parameter adjusting PC 5 which creates a distortion correction table as a correspondence map between the two-dimensional projection plane and a mesh model of the projection plane of arbitrary shape; and projectors 2a and 2b unit which project an image based on the image signal outputted from the image signal processing apparatus onto the screen. The distortion correction unit 3 receives the distortion correction table from the parameter adjusting PC 5 and performs distortion correction processing for each pixel of the two-dimensional image signal received by the image signal input unit with reference to the distortion correction table to generate the image signal to project the image light onto the projection plane of arbitrary shape. It is therefore possible to display images with reduced distortion of image light viewed by a viewer with a simple structure in real time.
