Abstract
Mobile communication or computing devices, and methods and systems for the operation of mobile communication devices; each involving a binary code in square form which has been encoded with binary data arrayed within the square form, whereby the code in square form includes at least one border not including binary data, but including code size indication data in the form of a repetitive sequence.
Claims43
A method of operation of a camera-enabled mobile communication or computing device;
- the method comprising:
- providing a code in square form which has been encoded with binary data arrayed within the square form, whereby the code in square form includes at least one border not including binary data, but including code size indication data in the form of a repetitive sequence;
- capturing the encoded information using the camera of a camera-enabled mobile communication or computing device;
- using the repetitive sequence to determine the size of the code;
- and
- decoding the encoded information.
A computer readable medium comprising at least computer program code for controlling a camera-enabled mobile communication or computing device;
- said computer readable medium comprising;
- computer code for providing a code in square form which has been encode with binary data arrayed within the square form, whereby the code in square form includes at least one border not including binary data, but including code size indication data in the form of a repetitive sequence;
- computer code for capturing the encoded information using the camera of a camera-enabled mobile communication or computing device;
- computer code for using the repetitive sequence to determine the size of the code;
- and
- computer for decoding the code information.
A mobile communication apparatus comprising:
- a camera;
- and
- a controller, wherein said controller is configured to:
- provide a code in square form which has been encoded with binary data arrayed within the square form, whereby the code in square form includes at least one border not including binary data, but including code size indication data in the form of a repetitive sequence;
- capture the encoded information using the camera of a camera-enabled mobile communication or computing device;
- use the repetitive sequence to determine the size of the code;
- and
- decode the encoded information.
