<p>The problem addressed by the present invention is providing an image display method that can superimpose projected images from projectors on a screen by a comparatively simple and easy method. To do so, in the present invention, a prescribed projected image that a first projector (10) projects on a screen (2) is imaged by a second projector (20) and an inverted image of the imaged observed image that has been inverted with respect to a perpendicular line is computed. In the second projector (20), an angle for which this inverted image and a corrected image for angular calculations, which is calculated by image correction with angle as a parameter, coincide is calculated. On the basis of angles of inclination alpha and -alpha for the first and second projectors (10, 20) calculated from this angle, image correction with angle as a parameter is carried out for each of the projectors (10, 20). The image correction with angle as a parameter is carried out such that an observed image seen from the direction of a normal line to the screen when the projectors are positioned at an inclination of a prescribed angle to the normal line to the screen forms a corrected image of the projected image.</p> |
