METHOD AND APPARATUS FOR STORING DATA

摘要

A method and an apparatus for storing data as a coded two-dimensional pattern of pixels on a photographic medium are described. An image representative of the data to be stored is divided into a two-dimensional array of blocks. A representative color value is determined for each block to obtain a two-dimensional array of representative color values. At least part of the data to be stored is coded such that the resulting coded two-dimensional pattern of pixels resembles the two-dimensional array of representative color values. The coded two-dimensional pattern of pixels is printed onto the photographic medium.

1. A method for storing data as a coded two-dimensional pattern of pixels on a photographic medium, the method comprising:
dividing an image representative of the data to be stored into a two-dimensional array of blocks; determining a representative color value for each block to obtain a two-dimensional array of representative color values; coding at least part of the data to be stored such that the resulting coded two-dimensional pattern of pixels resembles the two-dimensional array of representative color values, and printing the coded two-dimensional pattern of pixels onto the photographic medium.
