Title:
DATA ENCODING DEVICE AND DATA DECODING DEVICE
Document Type and Number:
WIPO Patent Application WO/2002/044997
Kind Code:
A1
Abstract:
A data encoding device comprises an encoding unit for converting data on a text, sound and a dynamic image with reference to a code conversion table (104, 204) to output color marks and a decoding unit for converting color marks with reference to a code inverse-conversion table (112, 212) to output the data on a text, sound and a dynamic image. High density recording is realized through color marks. A higher density recording than that of a bar code or a two-dimensional code of the prior art can be made by relating a unit of data to one of a plurality of colors when coding and decoding the data.
