    Abstract: This invention relates to an image display apparatus capable of displaying a high-definition image. An image display apparatus of this invention is characterized in that light beams from a plurality of image display elements (1) are displayed as continuous single image information via a hologram optical element (2). An image display apparatus of this invention is characterized by including a plurality of image display elements respectively assigned to different partial image information regions of an image to be displayed, and a hologram optical element for diffracting a plurality of light beams from the plurality of image display elements, and displaying the diffracted light beams as continuous single image information. An image display apparatus is also characterized by including a plurality of image display elements, each of the image display elements having a large number of pixels, and a hologram optical element for forming a synthesized image by diffracting a plurality of image light beams from the image display elements, wherein the hologram optical element diffracts the plurality of image light beams so as to display a synthesized image by interpolating information between pixels of a plurality of images to be synthesized.

    Abstract: A display optical system for guiding light from an original picture to an eye of an observer or a surface to have an image projected thereon is provided with a first optical system and a second optical system. The first optical system is provided with a first surface that is formed on a transparent body and has at least a reflecting action, a second surface for reflecting light reflected on the first surface toward the first surface again, and a third surface that is formed on the transparent body in the same manner as the first surface and transmits the light from the original picture. The light transmitted through the third surface travels toward the first surface and reflected for the first time on the first surface. In addition, a principal ray at central angle of view to be reflected for the last time on the first surface is reflected and travels to a side opposite to a side of the first reflection on the first surface with respect to a normal line of a surface on a hit point thereof. With such a structure, a small display optical system that is capable of widening an angle of view is realized.

    Abstract: A small optical system that is capable of widening an angle of view is provided. This optical system is provided with a first surface having a reflecting action and a second surface that reflects a light beam reflected on this first surface toward the first surface again. Then, a principal ray at central angle of view that is made incident on the first surface again is reflected and travels to a side opposite to a side of the last time it was reflected from the first surface with respect to a normal line of a surface at a hit point thereof.

    Abstract: An image display apparatus has a light source, a reflective display device, an illumination optical system for guiding light from the light source to the display device to illuminate the display device, and a display optical system for guiding the light reflected by the display device to the pupil of an observer to allow the observer to observe an image displayed on the display panel. The illumination optical system and the display optical system have an optical element shared in part or are arranged so as not to interfere with each other, thereby providing the image display apparatus of compact structure. Particularly, where the display optical system is a thin optical system having a plurality of decentered, reflecting, curved surfaces, the appropriate illumination optical system is arranged, thereby providing the thin image display apparatus using the reflective display device.

    Abstract: This invention relates to an image display method, which includes the steps mainly characterized by allowing the observer to stereoscopically view the three-dimensional partial image by guiding a light beam coming from the three-dimensional partial image to a predetermined position via a partial parallax barrier, which is formed by light directivity controlling means, arranged to oppose the image displaying means, by alternately arranging stripe-shaped light-transmitting portions and light-shielding portions on an area corresponding to the three-dimensional partial image; and controlling, using light amount adjusting means, the brightness levels of the partial images to be observed by the observer in correspondence with the view point numbers of the partial images.
