Mixed code, and method and apparatus for generating the same

摘要

A mixed code, and a method and apparatus for encoding the same are provided. The mixed code includes a first code image region storing a first code image obtained by encoding first information using color, shading, or a combination thereof, and a second code image region storing a second code image obtained by encoding second information using color, shading, or a combination thereof. The first code image and/or the second code image includes the results of encoding interpretation information, construction information, error control information, and code direction information. The mixed code is made by adjusting the difference in color and brightness between the first and second code images to a predetermined level and combining these images.

A computer readable storage medium having embodied thereon a mixed code a mixed code obtained by overlapping first information with second information in a region, the first and second information made using at least one of a character, a number, a sign, and an image, the mixed code comprising:
a first code image region storing a first code image obtained by encoding the first information and construction information regarding a second code image, the first code image made using colors, shading, or a combination thereof; and a second code image region storing the second code image obtained by encoding the second information, the second code image made using colors, shading, or a combination thereof, the second code image overlapping with the first code image, the colors and shading being distinguished from the colors and shading used in the first code image, using a predetermined threshold.
