ABSTRACT:
The printer for making 3D and animation pictures from a series of 2D images, according to the present invention, uses an electronic displaying device for sequentially displaying the 2D images. A projection lens is used to sequentially projecting the displayed 2D images, each at a different projection angle through a view-separating screen onto a photosensitive emulsion layer. The projection angles can be achieved or extended by tilting the emulsion layer together with the view-separating screen away from the image plane. Preferably, the electronic displaying means is also tipped to improve the focusing of the projection lens on the tilted image plane. In order to correct for the distortion in the projected image due to tilting and tipping, the 2D images are warped in accordance with the tilting and tipping angles prior to being displayed for exposure.
