A 3D printer that uses two video cameras with different magnification powers for acquiring images from 2D negatives for editing and key subject alignment. One video camera takes full view image for key subject selection and picture cropping, the other video camera which is used for acquiring image data for key subject alignment sees only an enlarged section of the image around the key subject. The printer also uses an automated image matching algorithm to find the relative location of the key subject in each frame. In particular, the algorithms are divided into a crude computation step and a fine computation step which reduces computation time. The printer uses a criterion to check whether the actual key subject alignment is satisfactory. The optics for printing and key subject alignment are assembled on a single mechanical stage to reduce mechanical errors.

In a printer for printing an image array on the photosensitive surface of lenticular print film from a set of 2-D views with a key subject image on each 2-D view, said printer having a negative carrier, and a projection lens mounted on a platform for printing said 2-D views onto lenticular print film, and means for moving said platform relative to said negative carrier and lenticular print film, an improvement comprising: (a) a printer being arranged as a single stage printer and having first optical means for editing the 2-D views and second optical means for locating the key subject image on each 2-D view, said first optical means for editing and second optical means for locating each being placed on said platform, and means for conveying the location of the key subject image to a computer which computes the actual location of the key subject image and controls the relative movement of the platform for correct alignment of the key subject image in each 2-D view in a set for printing.
