Three Dimension Movies Leap from Screen (Aug, 1931)
Three Dimension Movies Leap from Screen
PATENTS have recently been granted to Jacob Burkhardt of Detroit, Michigan, on a type of motion picture film which produces pictures having so realistic a three dimension effect that the actors seem almost to walk from the screen among the audience.
The new film has two pictures in a single frame, and the top and bottom of these pictures are parallel with the sides of the film instead of at right angles. The lower of the two pictures is the image or action picture while the upper is the background picture.
The background of the action picture is blacked out, as is the background picture in the space occupied by the foreground picture, so that the light from those sections of the film will not appear on the screen to mar the projection.
A refracting prism, placed in front of the lens, projects the side by side images as one complete picture on the screen. This prism also turns the image at right angles, so that it will appear right side up instead of standing on one end. Space has been allowed on the film for a sound track.
