Abstract

Provided are a method and system for controlling light by using an image code. The method includes displaying an image code on a display unit; acquiring information relating to light settings by recognizing the image code; determining apparatus information and lighting state information by using information relating to the light settings; and transmitting a light request message for requesting light settings according to the lighting state information to the lighting apparatus having apparatus information that is equal to the apparatus information of the image code.

Claims

1. A method of controlling light of a lighting apparatus by using an image code, the method comprising:

displaying an image code on a display unit;

acquiring information relating to light settings by recognizing the image code;

determining apparatus information and lighting state information by using the information relating to the light settings; and

transmitting a light request message for requesting light settings corresponding to the lighting state information to a lighting apparatus having the apparatus information.

2. The method of claim 1, wherein the information relating to the light settings includes at least one of the apparatus information and the lighting state information.

3. The method of claim 1, wherein if the image code includes the apparatus information and does not include the lighting state information, lighting state information of a light menu transmitted from the lighting apparatus is determined as the lighting state information.

4. The method of claim 3, further comprising displaying the light menu.

5. The method of claim 1, wherein if the image code includes the lighting state information and does not include the apparatus information, the apparatus information is obtained from apparatus information of accessible lighting apparatuses.

6. The method of claim 5, further comprising displaying a list of accessible lighting apparatuses.

7. The method of claim 1, wherein the apparatus information comprises at least one of an Internet protocol (IP) address of the lighting apparatus, a media access control (MAC) address of the lighting apparatus, and a product name of the lighting apparatus.

8. The method of claim 1, wherein the lighting state information is a ratio of red light, green light, and blue light emitted from the lighting apparatus.

9. The method of claim 1, wherein the image code may be at least one of barcode, quick response (QR) code, data matrix, portable data file (PDF)417, maxi code, color code, Gray code, or three-dimensional barcode.

10. The method of claim 1, wherein the image code is included in a preview image of a camera.

11. The method of claim 1, further comprising acquiring an image code including the apparatus information of the lighting apparatus and current lighting state information of the lighting apparatus, when an image code generation command is input.

12. A light control system comprising:

a lighting apparatus; and

a control apparatus comprising;

a display unit for displaying an image code;

a control unit for acquiring information relating to light settings by recognizing the image code and generating a light request message for requesting the light settings by using the information relating to the light settings; and

a communication unit for transmitting the light request message to the lighting apparatus.

13. The light control system of claim 12, wherein the information relating to the light settings includes at least one of apparatus information and lighting state information.

14. The light control system of claim 12, wherein if the image code includes the apparatus information and does not include the lighting state information, the control unit determines lighting state information of a light menu transmitted from the lighting apparatus as the lighting state information.

15. The light control system of claim 14, wherein the control unit displays the light menu on the display unit.

16. The light control system of claim 12, wherein the apparatus information comprises at least one of an Internet protocol (IP) address of the lighting apparatus, a media access control (MAC) address of the lighting apparatus, and a product name of the lighting apparatus.

17. The light control system of claim 12, wherein the lighting state information is a ratio of red light, green light, and blue light emitted from the lighting apparatus.

18. The light control system of claim 12, wherein the control apparatus further comprises a camera, and the image code is included in a preview image of the camera.

19. The light control system of claim 12, wherein the lighting apparatus comprises:

a light source;

a light source driving unit for driving the light source; and

a light control unit for controlling the light source driving unit according to a light request message requested by the control unit.

20. The light control system of claim 12, further comprising a relay apparatus for relaying communication between the lighting apparatus and the control apparatus via a network.
