  • Patent number: 6769783
    Abstract: A visual angle-dependent imaging device comprises a main body; a show window on a front side of the main body, a concave portion within the show window; an inner wall of the concave portion being installed with a three-dimensional concave sculpture with a specific pattern; a lamp seat at a bottom of the main body. The lamp seat is communicated with the concave portion of the main body. A light source is installed on the lamp seat for projecting light to the concave portion of the main body. When light emitted from the light source is projected to an inner surface of the concave portion, the light is reflected from different portions of the concave portion. When a viewer views the three-dimensional concave sculpture from different viewing angles of the show window, the three-dimensional concave sculpture will project to the eyes of the viewer with a different image dependent on the viewing angle of the viewer.
