3D photo printer with image distortion correction

摘要

A photographic printer for making 3D pictures or animation pictures from at least two 2D images on lenticular print material. The printer uses a monitor for sequentially displaying 2D images. A projection lens is used to project the displayed 2D images onto the print material. A tilting mechanism is used to tilt the print material for changing the projection angles. In order to correct for the distortion of images projected on the print material due to tilting, the 2D images are geometrically transformed according to the tilting angles. The same printer can be used to make 2D prints on regular photographic paper. The printer can be equipped with a plurality of projection lenses with different focal lengths so that pictures of different magnification factors can be made.
