    • PROBLEM TO BE SOLVED: To provide a display system that uses aspheric lenses, controls the distance at which a virtual image is projected from a user and minimizes the distortions of the virtual image.
      SOLUTION: Aspheric lenses 20 and 22 and displays 24 and 26 are arranged on a support section 14, the lenses are substantially made parallel to the surfaces of the displays, and the central axes of the lenses are extended along the normal direction, with respect to the surfaces of the displays. In the system, the virtual image appears at a prescribed distance which is smaller than the distance to a point at infinity from the user. Thus, the aspheric lenses and displays are arranged on the support section at a certain prescribed angle, that focuses with respect to the axes of the eyes of the user, when the user looks straight toward the front. The lenses and the displays are located at places where the prescribed prescribed angle is focused, with respect to the user's eyes and the user's eyes are directed inside with a natural, certain prescribed angle for the user who looks at the object body at a certain prescribed distance that is smaller than the distance to the point at infinity.

    • 要解决的问题:为了提供使用非球面透镜的显示系统,控制从用户投射虚拟图像的距离并且使虚拟图像的失真最小化。 解决方案:非球面透镜20和22以及显示器24和26布置在支撑部分14上,透镜基本上与显示器的表面平行,并且透镜的中心轴沿着法线方向延伸, 相对于显示器的表面。 在系统中,虚拟图像出现在比用户无穷远点的距离小的规定距离处。 因此,当用户直视前方时,非球面透镜和显示器以特定的规定角度布置在支撑部分上,该角度相对于使用者的眼睛的轴线进行聚焦。 透镜和显示器位于相对于用户的眼睛聚焦规定的规定角度的位置,并且用户的眼睛以特定规定的角度对待身体的用户以自然的,特定的规定角度被引导到内部 距离小于无限远点的距离。 版权所有(C)2006,JPO&NCIPI
