Abstract
A panoramic vision apparatus having a simple structure is provided which produces an image from which the viewer feels a natural stretch. A shooter and a display are each provided with a prism. The shooting range is changed by a rotation of the prism of the shooter and the projection position is changed by changing the direction of the projected light by a rotation of the prism of the display. The shooter outputs a direction signal representative of the direction of the prism of the shooter in synchronism with a video signal. The display sets the direction of the prism thereof in accordance with the direction represented by the signal to project an image.
