Abstract
A method is provided which sharpens three-dimensional images by using an unsharp masking technique subsequent to interleaving and before printing.
Claims16
A method of producing a high resolution hardcopy image comprising:
- interleaving a plurality of images to form a composite;
- and
- performing an unsharp masking technique on said composite, wherein said step of performing an unsharp masking technique includes:
- determining an intensity value "i" on a first waveform representing an original image;
- blurring said original image to provide a second waveform;
- determining a second intensity value "b" on said second waveform corresponding to said "i";
- determining a blending factor "a";
- and
- determining a resulting intensity value "h" on a third waveform representing said image having sharpened edges, said "h" corresponding to said "i" and said "b".

A method of producing three-dimensional hardcopy images comprising:
- digitizing and storing a plurality of generated images captured on frames;
- determining a common point to said plurality of frames;
- creating multiple images from off-axis perspective projections using said common point;
- storing said images;
- interleaving said images to form a composite;
- performing an unsharp masking technique on said composite to produce a sharper image;
- printing said sharper image using a hardcopy output device;
- and
- laminating said sharper image onto a lenticular surface, wherein said step of performing an unsharp masking technique on said composite includes:
- determining an intensity value "i" on a first waveform representing an original image;
- blurring said original image to provide a second waveform;
- determining a second intensity value "b" on said second waveform corresponding to said "i";
- determining a blending factor "a";
- and
- determining a resulting intensity value "h" on a third waveform representing said image having sharpened edges, said "h" corresponding to said "i" and said "b".
