An image display method for displaying a display image on optical scattering means by scattering a projected image, as projected from image projection means, with the optical scattering means. The image display method comprises a step of projecting a controlling image to be used for correcting the display image to be projected on the optical scattering means, from the image projecting means to the optical scattering means; a step of detecting the controlling image by a plurality of optical detection means disposed outside of an effective image display area in the optical scattering means; a step of generating an image correction signal on the basis of a detected signal of the controlling image by the optical detection means; and a step of projecting the projected image corrected on the basis of the image correction signal, on the optical scattering means. Consequently, the image display method can detect such a correction parameter precisely as reflects the distortion of the projected image precisely, while preventing the display image quality from being deteriorated by the presence of the optical detection means. |
