発明の名称 (英語) IMAGE DISPLAY DEVICE, PROCESSING METHOD, DETECTING METHOD, AND PROCESSING DEVICE
発明の概要(英語) This image display device (1) is provided with a light source unit that generates a plurality of light beams corresponding respectively to a plurality of pixels contained in an image, a projecting unit which forms a light path from the light source unit to an eye, and which directly projects the plurality of generated light beams on the retina of the eye through the light path, thereby forming the image on the retina, a branching unit that branches, on the light path, a plurality of reflected light beams from positions respectively corresponding to the plurality of pixels on a prescribed site of the eye, a detecting unit that detects the respective intensities of the plurality of branched reflected light beams, and a processing unit that obtains a parameter indicating the state of the site on the position corresponding to each of the plurality of pixels on the basis of the intensity of the generated light beams corresponding to each of the plurality of pixels and the detected intensity of the reflected light beams.
従来技術、競合技術の概要(英語) BACKGROUND ART
And mounted on the head of the human body, directly to the light by projecting the retina of the eye, the retina image formed by the image display apparatus has been known (for example, Patent Documents 1 and 2, as well as, non-patent document 1). For example, the image display apparatus, head-mounted display (HMD; Head Mounted Display) is expressed.
A projection method for the HMD used, the non-scanning method and scanning method has been known. Scanning system, corresponding to one pixel of the laser light 1, a plurality of pixels included in the image corresponding to an image by scanning a plurality of positions formed by the retina. Scanning in, for example, MEMS (Micro Electro Mechanical Systems) such as micro-mirrors are used. Non-scanning system, a plurality of pixels included in the image corresponding to each, and, in a plane that is arranged in a lattice pattern by generating a plurality of optical image formed by the retina.
In addition, to the retina of the eye of the subject is irradiated with light, the intensity of light reflected from the retina to a detection device has been known (for example, Patent Document 3 and 4, as well as, non-patent document 1). For example, the HMD of the non-patent document 1, the scanning system may be used to form an image on the retina. Further, this HMD is, to detect the intensity of the reflected light from the retina.
