Mixed code, and method and apparatus for generating the same
First Claim
1. 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, the first code image made using colors, shading, or a combination thereof; and
a second code image region storing a 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.

Abstract
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.

6. A method of generating a mixed code, comprising:
-
(a) encoding first information and second information into a first code image and a second code image made using colors, shading, shaping, a pattern, or a combination thereof, respectively, each of the first and second information being made using at least one of a character, a number, a sign, and an image; and
(b) producing a physical or electronic mixed code image by setting a difference in color and brightness between the first and second code images and combining the first and second code images according to the set difference. - View Dependent Claims (7, 8, 9, 10, 11, 12, 20)

13. A method of generating a mixed code, comprising:
-
(a) encoding first information made using at least one of a character, a number, and a sign into a first code image made using colors, shading, shaping, a pattern, or a combination thereof;
(b) encoding second information into a second code image made using colors, shading, shaping, a pattern, or a combination thereof, the second information obtained by performing at least one of adding new information to the first information and deleting and changing information in the first information;
(c) changing color and brightness of the second code image such that a difference in color and brightness between the first and second code images corresponds to a predetermined threshold; and
(d) mapping the changed second code image to the first code image. - View Dependent Claims (14)

15. An apparatus for generating a mixed code, comprising:
-
a code image generating unit encoding first information and second information into a first code image and a second code image which are using colors, shading, shaping, a pattern, or a combination thereof, the first and second information made using at least one of a character, a number, a sign, and an image; and
a code image combining unit producing a physical or electronic mixed code image by setting a difference in color and brightness between the first and second code images and combining the first and second code images based on the difference in color and brightness. - View Dependent Claims (16, 17, 18, 19)
