ABSTRACT:
The filmless method and printer for making 3D and animation pictures, using a matrix display to sequentially display a series of 2D views, and a projection lens to project the displayed images onto a lenticular print material, each at a different projection angle. In order to fill the image area underlying each lenticule on the lenticular print material with different 2D views, each 2D view must be projected onto the lenticular print material at different projection angle. Two methods can be used: 1) In the scanning method, two of the three elements including the matrix display, the projection lens and the lenticular print material are moved by mechanical means to different positions to change the projection angle; 2) In the non-scanning method, a large-aperture projection lens is used to project the 2D views sequentially displayed on the matrix display onto the lenticular print material such that each 2D view is projected through a different section the lens aperture. The 2D images for making 3D pictures are electronically aligned before they are conveyed to the display. Thus, the key-subject alignment process during printing is eliminated. The matrix display can be a video monitor or a light valve, such as an LCD or LED panel. Computer generated images can be used.
