2. Description of the Related Art In recent years, video screens have become larger and three-dimensional. On the other hand, it is desired that a device for viewing video images be made smaller and lighter. Wearable display devices have been developed. These devices project an electronic image on a two-dimensional image display device onto the retina of the eye via an optical system, and unlike the case of viewing a large conventional stationary screen display plate, the device is not portable. Because of its goodness and ease of attachment and detachment, it can be used in all places and situations. As conventional examples, there are spectacle type devices such as those disclosed in Japanese Patent Laid-Open Nos. 4-23579 and 4-26287.

By turning on the power switch 3,
As shown in FIG. 2, a photo sensor 5 provided outside the device operates to detect the brightness of the outside world. For the operation of the photo sensor 5, for example, in the case of an eyeglass-type device as shown in FIG. 2, the piezoelectric sensor 6 is provided on the support portion at the time of wearing such as the nose pad portion and the temple portion, and the piezoelectric sensor 6 is mounted at the time of wearing. The generated electric signal may be used as a use start signal of the device, and the device may be activated by this. Further, the brightness of the outside world may be detected by a monitor of the pupil diameter that changes depending on the brightness of the outside world, instead of the photosensor.

The initial value of the electronic image displayed on the two-dimensional image display element 2 is determined according to the brightness of the external environment detected by the photo sensor 5, but most typically, it is detected. Make it the same brightness as the outside world (Fig. 4). The brightness of the subsequent image is decreased with time from the initial value by the time counter circuit. It is preferable to reduce the brightness along the dark adaptation curve of the eye as shown in FIG. 3 from the viewpoint of reducing the burden on the eye. This curve is divided into a curve A and a curve B with the bending point C as a boundary. However, when the external brightness (initial value) detected by the photosensor 5 is in the area of the curve B, the brightness is Then decrease along curve B. It should be noted that the decrease in the brightness of the electronic image with time from the initial value is preferably performed along the dark adaptation curve of the eye as described above, but the decrease curve is strictly the dark adaptation of the eye. It is not necessary to follow the curve, and according to the curve located slightly above the curve, and even if the stability level is slightly higher than the stability level of the dark adaptation curve of the eye, it is effective in reducing the burden on the eye.

Next, FIG. 4 shows an example of temporal changes in the brightness of the outside world and images. When reproducing a recording medium such as a video, a CD-ROM, or a laser disk, the brightness of the external environment is re-detected a predetermined time before the end of the source program, and the brightness of the electronic image to be displayed is gradually changed to that of the external environment. It is more preferable to increase in accordance with, for example, a light adaptation curve so that the outside world after the end of the image can be comfortably seen without depending on the light adaptation of the eye. In the example of this figure, the initial value and the end value of the brightness of the image are made equal to those of the outside world, but they do not necessarily have to be equal.
