発明の名称 (英語) IMAGE DISPLAY DEVICE USING RETINAL SCAN DISPLAY UNIT AND METHOD THEREFOR NEW コモンズ
発明の概要(英語) In the present invention, when visibly displaying a given image for a user (USR), the direction of the user's gaze is detected. Letting a first image be a portion assumed to exist in the detected direction of the user's gaze and a second image be an image complementary to the first image with respect to the given image, the first image is focused and displayed at a first distance away from both eyes of the user by scanning laser light at the retinal position of both eyes of the user from a user's head-mounted retinal scan display unit (20). Furthermore, the second image is displayed on the panel surface of a panel display unit (50) provided at a second distance away from the user, the second distance being shorter than the first distance. Thus, it is possible to suitably present a given image to a user.
従来技術、競合技術の概要(英語) BACKGROUND ART
(Hereinafter, referred to as user) of a person from the conventional field of view by covering as much as possible, to improve the immersive feeling of the user have been proposed various display device. For example, in Patent Document 1, a plurality of large-sized display device is prepared, can be arranged so as to surround the user, thereby increasing the sense of immersion. Such an apparatus configuration, a liquid crystal display device if the distance of the user, a relatively small display device can cover many of the field of view, the distance to the display device becomes small, the feeling is easily lost. For this reason, a certain distance from the user and then, is made for a large-screen display is obtained, for example in Patent Document 2, the projection-type display device utilizing the curved projection surface, the user field of view covers a large portion of the configuration of the high sense of immersion has been proposed.
On the other hand, the display device of the head are arranged in close proximity to the eye and thereby enhancing the coverage of the field of view, the image formed by the virtual user can be away from the position of the image, the display device can be downsized and at the same time and the appearance of immersive technology attempts, have been proposed various (for example, Patent Document 3).
In addition, such large display device or in a head-mounted display, the human visual recognition ability, high in the central portion of the field of view to be low at the peripheral portion, than the resolution of the image displayed on the center of a field in the vicinity of the rough resolution, rendering time and to reduce the load of the image formation can be shortened and the like are also proposed (Patent Document 4, 5). Is mounted, Patent Document 3 as illustrated, such as liquid crystal or organic EL display unit of the mirror image is formed, this image using an optical system of the type visible to the user as a virtual image of the other, a small laser light is directly incident to the retina using an optical system and, the user positions separated by a predetermined distance from the display image can be focused also known type (for example, Patent Document 6).
