ABSTRACT:
An automatic vision display apparatus has a flight object having a floating gas filled therein to fly, flying along a vertical wall surface and including a screen mounted at an opposite side to the vertical wall surface; a propulsion unit mounted at a predetermined position of the flight object and moving the flight object; a control unit mounted to the flight object and controlling the propulsion unit; a projector projecting an image on the screen of the flight object at a distance from the flight object; an adjusting unit adjusting an image projecting direction of the projector; and a main control unit controlling the projector to project the image and controlling the adjusting unit so that the projector tracks a movement of the flight object to project an image. According to the invention, it is possible to project an image while automatically tracking the screen of the flight object being flying. In addition, it is possible to correct a distortion of the projected when the screen of the flight object consists of the three dimensional curved surface.
