It is possible to further reduce the fatigue of the user by presenting the image. That is, since the distance of the virtual image formed by the image display panel and the lens is continuously adjusted according to the pupil distance of each person, the distance of the presented virtual image and the distance of the virtual image due to binocular parallax are surely matched and used. This can further reduce the fatigue of the person.

Alternatively, a camera is used in the image generating unit, and the distance to the object is determined by the focal length of the camera or a distance measuring device provided separately, and according to the distance,
It is also desirable that the virtual image distance in the fixed head image display device be continuously controlled.

In this case, it is preferable that the left and right eyes of the user have an image generation unit or a camera that presents the same image, and the virtual image is continuously controlled according to the distance determined as described above. .

By linking with the virtual image distance, it is possible to realize a realistic image presentation and increase the immersive feeling. On the other hand, in the head-fixed image display device, since the device is fixed to the user's head, there is no change in the image that normally occurs due to the movement of the head, and there is little sense of realism and discomfort. I may feel.
