PURPOSE:To reduce distortion around an image although the more a distance between a viewpoint and a projected plane is reduced, the more the distortion around the projected image is enlarged when a projecting object is projected by a general-purpose center projecting method concerning the center projecting method for projecting the projecting object on the projected plane by emitting a beam from the view point in the shape of a cone. CONSTITUTION:After or when the projecting object is projected onto the projected plane composed of a plane, the distortion is corrected by projecting it again onto the projected plane by eyeball conversion. In this case, the eyeball conversion is the reprojection onto the projected plane through the projection onto a projected plane (projected spherical plane) defining a semispherical plane farther from the view point as this projected plane among the two semispherical planes provided by bisecting a spherical plane, which is provided with a center on a line of sight, orthogonally to the line of sight at that center position after or when the projecting object is projected onto the projected plane. |
