Method and apparatus for optimizing depth images by adjusting print spacing
First Claim
1. A method of producing a depth image, comprising the steps of:
- (a) producing image line sets where corresponding image lines in each of the sets corresponds to a different depth image view;
(b) fixing the sets in a display media in alignment with lenticules of a lenticular overlay by continuously varying a spacing between the sets by scanning in a direction aligned with the lenticules; and
(c) projecting the depth image to a viewer using the fixed image line sets.

Abstract
A method and apparatus for producing the image elements of a lenticular image. The lenticular image includes a plurality of composite images of the same scene where each composite image includes image lines. The image lines of one composite view are interleaved with the image lines forming the other composite images to create image line sets. The sets include one image line from each composite image. The sets of image lines are aligned with the lenticules of a lenticular overlay by adjusting the spacing between the image line sets, so that the sets are in optimum alignment or phase relationship with each lenticule of the lenticular overlay. The spacing between image lines and/or between scan lines and/or image line sets can be adjusted to correct phase errors. The scan lines are printed in a fast scan direction of a printer in alignment with the lenticules.
