Abstract

System and method forms a lenticular viewing card having viewable depth or motion images by processing an original image into digital form and sampling and shifting the processed original image into at least two frames of images shifted perpendicular to the lenticular direction from each other by being sampled at different points. These frames of images are sliced and interlaced into a merged image that is printed and positioning into a viewing position with a lenticular lens sheet to permit a sequential viewing of the frames making up the merged image as a function of a user'"'"'s viewing angle.

Claims

1. A method for forming a lenticular image having viewable depth or motion effects, comprising the steps of:

providing a lenticule sheet having a plurality of lenticules trrayed in a given direction,

interlacing at least two frames of the same image with at least one frame sequentially displaced perpendicular to said given direction; and

positioning said lenticule sheet of so as to view the image content of the interlaced frames of the same image.

2. A method according to claim 1, wherein the at least two frames of similar image content are derived is digitally and where each frame is derived by sampling the single image at a different sampling position sequentially displaced perpendicular to the lenticular direction by at least one pixel and recorded onto a support base in interleaved slices with the sheet of lenticular material attached to the image base with each lenticule in registration with corresponding interleaved slices.

3. The method according to claim 2 wherein each frame is displaced perpendicular to the lenticular direction by at least one pixel and recorded onto a support base in interleaved slices;

and

said sheet of lenticular material is attached to an image base with each lenticule in registration with corresponding slices.

4. A method for forming a lenticular card having viewable depth or motion images, comprising the steps of:

a) obtaining at least two frames of the same image;

b) displacing each frame perpendicular to a lenticular direction and recording onto a support base in interleaved slices; and

c) laminating a sheet of lenticular material having a plurality of elongated lens elements the length of each defining the lenticular direction to said support base with each lenticule in registration with corresponding slices.

5. An imaging method comprising the steps of:

a) processing an image of a subject into a plurality of images by sampling at different positions;

b) merging the plurality of sampled images to provide merged interlaced images; and

c) positioning the merged images with respect to a sheet of lenticular lenses in a viewing position to permit viewing of the plurality of images.

6. The imaging method according to claim 5 and further comprising the steps of:

prior to processing an image, digitizing the images into pixels and displacing the sample points of at least one of the plurality of images of step a) by at least one pixel.

7. The imaging method according to claim 5 and further comprising the steps of:

displacing at least two of the plurality of images in a direction perpendicular to the directions that the images are sliced.

8. A card supporting interlaced images for viewing through a lenticular sheet manufactured in accordance with the method steps of claim 5.

9. A method for forming an image comprising the steps of:

a) forming multiple frames of image data by repeatably sampling an original image with at least one of the samplings being displaced in position from a preceding sampling;

b) interleaving the samples from each of the multiple frames; and

c) positioning the interleaved multiple frames with respect to a lenticular sheet having a plurality of lenticular lenses into viewing alignment.

10. A method for forming an image according to claim 9 wherein the samplings of the original image are displaced perpendicular to the line of interleaving used t6 join the samples from each of the multiple frames of sliced image data.

11. A method for forming an image according to claim 10 and further comprising the steps of:

a) sampling a plurality of original images;

b) interleaving the samples from all of the sampled original images to form a merged interleaved image.

12. A method for forming an image according to claim 11 and further comprising the step of printing the merged interleaved image onto a supporting media for viewing.
