An image display method of the exemplary embodiments, in which a projection image projected from an image projection device is scattered by a light scattering device, thereby displaying a display image on the light scattering device, the image display method includes: projecting a control image, which is used to correct the display image to be projected onto the light scattering device, from the image projection device toward the light scattering device; detecting the control image by a plurality of photodetection devices disposed outside an effective image display region on the light scattering device; generating an image correction signal, based on control image detection signals from the photodetection devices; and projecting onto the light scattering device the projection image corrected based on the image correction signal. A correction parameter, having accurately reflected thereon a distortion of the projection image, can be detected with accuracy, and a reduction in display image quality is discouraged or prevented from occurring due to the presence of the photodetection device. |
