A method and apparatus for optimizing viewing distance for a stereogram
system. In a stereogram, an image is held in close juxtaposition with a
lenticular screen. In the invention, a data store is used to store
optimum pitch values for specified viewing distances. An interdigitation
program then acts on the table values and creates a mapping of
interdigitated views for each viewing distance. The user can then select
or specify a desired viewing distance, and the optimum mapping of views
is automatically chosen for display.
