And is detected by the light receiving sensor 42. Then
In response to a signal indicating wearing of glasses from the light receiving sensor 42, the light emitting sensor 16 formed at the approximate center of the upper edge of the frame 20c of the glasses 12c emits light. Selects a stereoscopic image, and the monitor 14 displays the stereoscopic image.

要はなく、装置の簡素化が図れる。Therefore, according to the stereoscopic display device 10 using the spectacles 12c, the observer 24 can display images not only when the spectacles 12c are worn, but also when the spectacles 12c are not worn. It can be recognized normally and does not cause discomfort. In addition, since the light is emitted toward, for example, the forehead of the observer 24 at a close distance from the glasses 12c, the presence or absence of the glasses is determined, so that not only the image corresponding to the presence or absence of the glasses can be accurately displayed, but also a separate reflecting member is provided. There is no need, and the device can be simplified.
