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 from the image code;

determining whether the acquired information relating to light settings includes apparatus information and lighting state information;

when it is determined that the acquired information relating to light settings includes apparatus information and lighting state information, acquiring the apparatus information and lighting state information from the information relating to the light settings;

when it is determined that the acquired information relating to light settings includes apparatus information and does not include lighting state information, acquiring the lighting state information from a lighting apparatus having the apparatus information;

determining whether there are a plurality of lighting apparatuses generating light, and, when it is determined that there are a plurality of lighting apparatuses generating light, displaying a list of the plurality of lighting apparatuses generating the light; and

transmitting a light request message for requesting light settings corresponding to the lighting state information to the 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, further comprising:

when it is determined that the image code includes the apparatus information and does not include the lighting state information, transmitting lighting state information of a light menu from the lighting apparatus and determining the transmitted lighting state information of the light menu as the lighting state information.

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

5. The method of claim 1, further comprising:

when it is determined that the image code includes the lighting state information and does not include the apparatus information, obtaining the apparatus information 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 is 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 mage of a camera.

11. The method of claim 1, further comprising:

when an image code generation command is inputted, acquiring an image code including the apparatus information of the lighting apparatus and current lighting state information of the lighting apparatus.

12. A light control system, comprising:

a lighting apparatus having apparatus information; and

a control apparatus comprising;

a display unit configured to display an image code;

a control unit configured to acquire information relating to light settings from the image code, determine whether the acquired information relating to light settings includes the apparatus info nation of the lighting apparatus and lighting state information, acquire the apparatus information of the lighting apparatus and lighting state information from the information relating to the light settings when the control unit determines that the acquired information relating to light settings includes the apparatus information and lighting state information, acquire lighting state information from the lighting apparatus when the control unit determines that the acquired information relating to light settings includes the apparatus information and does not include lighting state information, determine whether there are a plurality of lighting apparatuses generating light, display, when the control unit determines that there are a plurality of lighting apparatuses generating light, a list of the plurality of lighting apparatuses generating the light, and generate a light request message for requesting the light settings corresponding to the lighting state information; and

a communication unit configured to transmit 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 when the control unit determines the image code includes the apparatus information and does not include the lighting state information, the lighting apparatus is configured to transmit lighting state information of a light menu and the control unit is configured to determine the transmitted lighting state information of the light menu 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 configured to drive the light source; and

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

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