Image display apparatus

An image display apparatus comprising:

• 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 provided with a plurality of elementary hologram optical elements having an optical power corresponding to said plurality of image display elements, wherein
• each of said elementary hologram optical elements diffracts light from a corresponding one of said image display elements, said plurality of diffracted light traveling to a single pupil of an observer positioned at a predetermined position with respect to said hologram optical element, so that a virtual image by each said image display element is formed on the same virtual image plane to allow the observer to observe the virtual image as a single continuous virtual image.

An image display apparatus comprising:

• a plurality of image display elements, each of said image display elements having a plurality of pixels;
• and
• a hologram optical element provided with a plurality of elementary hologram optical elements having an optical power corresponding to said plurality of image display elements, wherein
• each of said elementary hologram optical elements diffracts light from a corresponding one of said image display elements, said plurality of diffracted light traveling to a single pupil of an observer positioned at a predetermined position with respect to said hologram optical element, so that a virtual image by each said image display element is formed on the same virtual image plane to allow the observer to observe the virtual image as a single continuous virtual image, and
• wherein said 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.

A 3-dimensional image display apparatus, which allows recognition of a 3-dimensional image by presenting two pieces of image information having a parallax therebetween to two systems for right and left eyes, comprising:

• first image display means for the right eye;
• second image display means for the left eye;
• each of said first and second image display means having a plurality of image display elements, and said plurality of image display elements being assigned to different partial image information regions of an image to be displayed,
• first deflection means for the right eye;
• and
• second deflection means for the left eye,
• each of said first and second deflection means having a plurality of elementary hologram optical elements having an optical power corresponding to said plurality of image display elements, wherein
• each of said elementary hologram optical elements diffracts light from a corresponding one of said image display elements, said plurality of diffracted light traveling to a single pupil of an observer positioned at a predetermined position with respect to said first and second deflection means, so that a virtual image by each said image display element is formed on the same virtual image plane to allow the observer to observe the virtual image as a single continuous virtual image.
