Claim 15

Independent Claim 141 words

A method of displaying a three dimensional visual image comprising the steps of: generating a viewing screen by exposing photographic film to light which has passed through a lenticular screen thereby generating a series of substantially parallel lines which are of a predetermined width and separated by clear spaces; generating a photographic image on a transparency with said image comprising a series of substantially parallel image segments generated by exposing said transparency to light which has passed through said lenticular screen; spacing said viewing screen from said photographic image on said transparency by a predetermined distance; aligning said substantially parallel lines on said viewing screen with said substantially parallel image segments on said transparency; and maintaining said viewing screen in a fixed, substantially parallel orientation with respect to said photographic image on said transparency to display said three dimensional visual image.

Claim 16

Independent Claim 141 words

A method of displaying a three dimensional visual image comprising the steps of: generating a viewing screen by exposing photographic film to light which has passed through a lenticular screen thereby generating a series of substantially parallel lines which are of a predetermined width and separated by clear spaces; generating a photographic image on a transparency with said image comprising a series of substantially parallel image segments generated by exposing said transparency to light which has passed through said lenticular screen; spacing said viewing screen from said photographic image on said transparency by a predetermined distance; aligning said substantially parallel lines on said viewing screen with said substantially parallel image segments on said transparency; and maintaining said viewing screen in a fixed, substantially parallel orientation with respect to said photographic image on said transparency to display said three dimensional visual image.

Claim 17

Dependent Claim 14 words

Claim 19

Independent Claim 239 words

A method of displaying a three dimensional visual image comprising the steps of: generating a first screen with a series of substantially parallel lines by exposing photographic film to light which has passed through a lenticular screen thereby generating a first series of substantially parallel lines which are of a predetermined width and separated by clear spaces; generating a photographic image on a first transparency by exposing said transparency to light which has passed through said lenticular screen with said photographic image comprising a first series of substantially parallel image segments of a predetermined size; enlarging said first screen by a predetermined factor to generate a viewing screen which includes a second series of substantially parallel lines which are of a width equal to said predetermined width multiplied by a predetermined factor and separated by clear spaces; enlarging said first transparency by said predetermined factor to generate a second transparency with a photographic image comprising a second series of substantially parallel image segments which are of a size equal to said predetermined size multiplied by said predetermined factor; spacing said viewing screen from said second transparency by a predetermined distance; aligning said second series of substantially parallel lines on said view screen with said second series of substantially parallel image segments on said second transparency; and maintaining said viewing screen in a fixed, substantially parallel orientation with respect to said second transparency to display said three dimensional visual image.

Claim 20
