Parallax ghosting is mitigated in a mounted lenticular grating with for many-frame animation by having lenticules at an offset angle a relative to the viewing vertical and incorporating ghosting in the base images. Where Ω is an angular range orthogonal to the longitudinal axes of the lenticules over which m picture slices in the base graphic are viewable, Vis the distance between the viewer's eyes, and L is the distance of the viewer from the lenticular grating, the number N of picture slices viewed due to the parallax effect given by N = 2 {m /Ω) arctan(V |cos α| /2 L) The above variables are chosen such that the number N of viewed picture slices is not too large. Ghosting of foreground images from neighboring frames is added to mitigate parallax-induced washing-out of colors. To create a three- dimensional effect, ghosted images are shifted in position by an amount related to their intended distance out-of-plane. |
