  • Publication number: 20240053822
    Abstract: It is possible to guide a mounting state of a head-mounted image display device to a visually recognizable region that is a correct design position. A head-mounted image display device 100 includes an image acquisition unit 104 that acquires a positional relationship image from which a positional relationship between a pupil position of an eyeball of a user and a visually recognizable region of the user can be estimated and a projection system 103 onto which incident light is projected, and the visually recognizable region is a focal position of the projection system 103. Further, the image display device 100 includes an imaging element, and the imaging element acquires the three-dimensional positional relationship image.

  • Patent number: 9726890
    Abstract: An image display device includes an image generating device, a light guide unit, and a light beam expanding device. The light guide unit includes a light guide plate, a first deflector, and a second deflector. The light beam expanding device expands a light beam incident from the image generating device along the Z direction and outputs the light beam to the light guide unit when the incident direction of light incident on the light guide plate is defined as the X direction and the propagation direction of light in the light guide plate is defined as the Y direction. The light beam expanding device is composed of a first reflective mirror on which light from the image generating device is incident and a second reflective mirror on which light from the first reflective mirror is incident and that outputs light to the light guide unit.
