Abstract
There is provided an encoding method for encoding a two-dimensional code using an encoder, wherein in accordance with a predetermined area allocation policy, the encoder generates a primary two-dimensional tally code having a primary effective area containing primary distribution information and a primary dummy area, and generates a secondary two-dimensional tally code having a secondary effective area containing secondary distribution information and disposed in a position where the primary dummy area is disposed and a secondary dummy area disposed in a position where the primary effective area is disposed.
Claims19
An encoding method for encoding a two-dimensional code using an encoder,
- wherein in accordance with a predetermined area allocation policy, the encoder generates a primary two-dimensional tally code having a primary effective area containing primary distribution information and a primary dummy area, and
- generates a secondary two-dimensional tally code having a secondary effective area containing secondary distribution information and disposed in a position where the primary dummy area is disposed and a secondary dummy area disposed in a position where the primary effective area is disposed.
A decoding method for decoding a two-dimensional code using a decoder,
- wherein the decoder obtains a primary two-dimensional tally code having a primary effective area containing primary distribution information and a primary dummy area,
- obtains a secondary two-dimensional tally code having a secondary effective area containing secondary distribution information and disposed in a position where the primary dummy area is disposed and a secondary dummy area disposed in a position where the primary effective area is disposed, the primary two-dimensional tally code and the secondary two-dimensional tally code being generated in accordance with a predetermined area allocation policy,
- cuts out the primary effective area and the secondary effective area in accordance with the area allocation policy, and
- disposes the primary effective area and the secondary effective area in positions corresponding to positions where the primary effective area and the secondary effective area are disposed before the primary effective area and the secondary effective area are cut out to thereby combine the primary effective area and the secondary effective area as a data area of the two-dimensional code.
An encoder configured to in accordance with a predetermined area allocation policy generate a primary two-dimensional tally code having a primary effective area containing primary distribution information and a primary dummy area, and generate a secondary two-dimensional tally code having a secondary effective area containing secondary distribution information and disposed in a position where the primary dummy area is disposed and a secondary dummy area disposed in a position where the first effective area is disposed.
A decoder configured to obtain a primary two-dimensional tally code having a primary effective area containing primary distribution information and a primary dummy area, obtain a secondary two-dimensional tally code having a secondary effective area containing secondary distribution information and disposed in a position where the primary dummy area is disposed and a secondary dummy area disposed in a position where the primary effective area is disposed, the primary two-dimensional tally code and the secondary two-dimensional tally code being generated in accordance with a predetermined area allocation policy, cut out the primary effective area and the secondary effective area in accordance with the area allocation policy, and dispose the primary effective area and the secondary effective area in positions corresponding to positions where the primary effective area and the secondary effective are disposed before the primary effective area and the secondary effective area are cut out to thereby combine the primary effective area and the secondary effective area as a data area of the two-dimensional code.
