Parallax panoramagram having improved depth and sharpness
First Claim
Patent Images
1. A method for forming a parallax panoramagram, comprising:
- providing a plurality of digitized images having parallax therebetween, each image being defined as a plurality of pixels;
slicing each of the digitized images into a plurality of corresponding vertical image stripes, each image stripe having a width being defined as a cluster of pixels;
ordering the corresponding image stripes into columns; and
increasing the contrast between adjacent pixels at a boundary between two columns by shrinking the size of the image stripes so that more image stripes fit into the columns, and assigning a color value to a last image stripe of one column and a first image stripe of a next column, wherein the assigned color value is determined by averaging the color values of a second-to-last image stripe in the one column with a second image stripe in the next column.

Abstract
A parallax panoramagram has increased depth and sharpness when a sharpness filter is applied after interdigitation of multiple image portions. An optical path of wave train (204) (on-axis) and wave train (205) (off-axis) intersect a single lenticle (201). The lenticle has a focal length (208) and the on-axis (204) and off-axis (205) wave trains correspond to different stripes. These wave trains (204 and 205) comme to focus at points (206 and 207) respectively. The surface (202) has a cylindrical curvature, and bracket (203) denotes the width of the lenticle (201). Each eye of the observer sees its own perspective view when looking at a lenticular stereogram.
