And is detected by the light receiving sensor 42. Then,
In response to a signal from the light receiving sensor 42 indicating that the eyeglasses are worn, the light emitting sensor 16 formed in the substantially central portion of the upper edge of the frame 20c of the eyeglass 12c emits light, and when the light receiving sensor 18 detects the light, the image selection circuit 28. Selects a stereoscopic image, and the stereoscopic image is displayed on the monitor 14.

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 the image not only when the spectacles 24 are wearing the spectacles 12c but also when the spectacles 12c are not wearing. Normal recognition and no discomfort. Further, since it is determined whether or not the eyeglasses are worn by the observer 24 who is at a short distance from the eyeglasses 12c, for example, the presence or absence of the eyeglasses is judged, so that not only an image corresponding to the presence or absence of the eyeglasses can be accurately displayed, but also a separate reflection member is provided. There is no need, and the device can be simplified.
