Abstract
An apparatus for receiving visible light data, including an image acquirer configured to acquire an image including a color code, the color code including a data region and a reference region; a detector configured to detect in the acquired image an object having a shape corresponding to the color code, determine a reference candidate region in the object, and determine the object to be the color code by comparing property information of the reference region with the determined reference candidate region; and a demodulator configured to demodulate visible light data from the data region.
Claims21
An apparatus for receiving visible light data, the apparatus comprising:
- an image acquirer configured to acquire an image including a color code, the color code including a data region and a reference region;
- a detector configured to detect in the acquired image an object having a shape corresponding to the color code, determine a reference candidate region in the object, and determine the object to be the color code by comparing property information of the reference region with the determined reference candidate region;
- and
- a demodulator configured to demodulate visible light data from the data region.
An apparatus for transmitting visible light data, the apparatus comprising:
- an acquirer configured to acquire a data region including data cells and to generate a color code by arranging a reference region including reference cells at a preset position with respect to the data region;
- and
- a display configured to display an image including the generated color code,
- wherein at least one object having a shape corresponding to the color code is identified by property information of the reference region.
A method for receiving visible light data, the method comprising:
- acquiring an image including a color code, the color code including a data region and a reference region;
- detecting in the acquired image an object having a shape corresponding to the color code;
- determining a reference candidate region in the object;
- determining the object to be the color code by comparing property information of the reference region with the determined reference candidate region;
- and
- demodulating visible light data from the data region.
A method for transmitting visible light data, the method comprising:
- acquiring a data region including data cells;
- generating a color code by arranging a reference region including reference cells at a preset position with respect to the data region;
- and
- displaying an image including the acquired color code,
- wherein at least one object having a shape corresponding to the color code is identified by property information of the reference region.
