Patent ID: 7796753

Claim:
An automated method for digitally encoding an image using a data processor, the method comprising: providing a first digitized input image; dividing the first digitized input image into a number of elemental input image segments each having an input segment length dimension and a common input segment width dimension sized so that the number of elemental input image segments per inch is equal to or a multiple of a decoder lens frequency; resizing the elemental input image segments to form corresponding output image segments each having an output segment length dimension equal to the length dimension of the corresponding input segment and a common width dimension that is a function of the input segment width dimension and a scrambling factor, the output segment being resized about a lengthwise segment centerline; and forming a first encoded output image from the output image segments, the first encoded output image being configured so that the output image segments retain a number of output image segments per inch that is equal to the number of elemental input image segments per inch and so that if the first encoded output image is printed, the first digitized input image can be discerned by viewing the printed encoded output image through a lenticular lens having the decoder lens frequency.
