It is an object of the present invention to provide a stereoscopic image displaying method and a stereoscopic image displaying apparatus using the same, which are capable of excellently observing a stereoscopic image. In order to achieve the object, a stereoscopic image forming apparatus of the present invention is configured such that display light from an image corresponding to a viewpoint of one parallax image on an image displaying device, on which parallax images corresponding to a plurality of different viewpoints can be displayed, is guided to an optical modulator, on which a light transmitting section and a light shielding section can be formed, by a second optical system disposed in the front of the image displaying device, and that the display light transmitted through the light transmitting section of the optical modulator is collected at a position that is a predetermined distance apart corresponding to the viewpoint on an observation surface by a first optical system, and the entire screen of a parallax image to be displayed on the image displaying device is thereby caused to be incident on each eye by controlling transmitted light from the optical modulator in synchronism with the switching of parallax images to be displayed on the image displaying device when an observer attains stereoscopic viewing of the image information on the image displaying device.
A stereoscopic image displaying method, wherein, when image information displayed on an image displaying device is observed three-dimensionally by guiding display light from an image corresponding to a viewpoint of one parallax image on said image displaying device, on which parallax images corresponding to a plurality of different viewpoints can be displayed, to an optical modulator, on which a light transmitting section and a light shielding section can be formed, by a second optical system disposed in the front of said image displaying device, and collecting the display light transmitted through said light transmitting section of said optical modulator at a position, which is a predetermined distance apart, corresponding to the viewpoint on an observation surface, by a first optical system, the entire screen of a parallax image to be displayed on said image displaying device is caused to be incident on each eye by controlling transmitted light from said optical modulator in synchronism with the switching of parallax images to be displayed on said image displaying device.
A stereoscopic image displaying method, wherein each of parallax images corresponding to a plurality of different viewpoints is made a predetermined stripe image, display light, which is from a stripe image corresponding to one viewpoint of a synthesized parallax image on an image displaying device that can alternately display a synthesized parallax image in which the stripe images is arranged in a predetermined order and synthesized and a synthesized parallax image in which the arrangement is changed, is guided to an optical modulator, which is formed in synchronism with the change of a synthesized parallax image that displays a predetermined pitch of light transmitting section and light shielding section by a second optical system disposed in the front of said image displaying device, display light that has transmitted through said light transmitting section of said optical modulator are collected at a position corresponding to a viewpoint on an observation face by a first optical system, and stereoscopic observation of image information displayed on said image displaying device is thereby performed.
