Abstract:
A biocular image display apparatus, comprising:a left image display surface for a left eye;a right image display surface for a right eye:a left optical system through which an observer's left eye observes an image displayed by said left image display surface as a virtual image for the left eye; anda right optical system through which an observer's right eye observes an image displayed by said right image display surface as a virtual image for the right eye; andan image distorting device that causes said left and right image display surfaces to display said left and right images distorted so that when the observer views said left and right virtual images as a single image by fusing said two images in his/her brain, observer's left and right visual lines can intersect substantially in an ideal virtual image plane, which is a virtual image position ideal for said observer's visual perception,wherein said image distorting device includes a device for distorting the images displayed on said left and right image display surfaces so that both a point of intersection between said observer's left and right visual lines formed when the observer sees the virtual images through images displayed at right-hand edges of said left and right image display surfaces and a point of intersection between said observer's left and right visual lines formed when the observer sees the virtual images through images displayed at left-hand edges of said left and right image display surfaces shift to an ideal virtual image plane containing a point of intersection between observer's left and right visual lines formed when the observer sees the virtual images through images displayed in central portions of said left and right image display surfaces.
