A three-dimensional observation apparatus includes a pair of image projection means, an image display means, a position detecting means for detecting movements of an observer of images displayed by the image display means, and a driving means for tracking movements of the observer and for moving the image display means based on changes of signals that are output from the position detecting means. The pair of image projection means and the image display means are configured such that the pair of image projection means projects a right eye image and a left eye image, and the image display means presents these images to the right eye and left eye, respectively, of an observer. A diffusing means may be provided to enlarge the exit pupils of the three-dimensional observation apparatus.

A stereoscopic image display device is for use with shutter glasses having left and right shutter lenses and includes a display processor, a display screen, a signal generator, and a signal transmitter. The display processor is for receiving a video input signal and outputting a video output signal sequence according to a frame sync signal acquired from the video input signal. The display screen is for receiving the video output signal sequence corresponding to a sequence of left-eye and right-eye images and displays the left-eye and right-eye images in an alternating manner according to the frame sync signal. The signal generator is for generating a shutter sync control signal that is transmitted to the shutter glasses by the signal transmitter for controlling duty cycles of alternating operations of the shutter glasses according to the frame sync signal.
