Electronic apparatus for displaying image using visual afterimage of light source
An electronic apparatus for displaying an image by using visual afterimage of a light source, the apparatus comprises a communication unit performing data communication to a light source; a control unit controlling light emission of the light source; a body storing the communication unit and the control unit; and a fixing unit for attaching the body on a body of a user, wherein the light source provides an image based on changes in spatial position of the light source.
1. A method of displaying an image by using a light source, the method comprising steps of:
receiving an image data from an external device, the image data comprising at least one of an image or text;
determining a portion of image data to be distributed to one or more display devices based on an interaction with the one or more display devices;
performing an authorization procedure to distribute the image data in response to an authentication authority or server; and
controlling the distribution of image data as a result of determining step,
wherein the determining step comprises dividing the image data into one or more portions automatically or manually, in consideration of at least one of the number of image data to be generated, the number of the display devices for receiving the image data, and a position of the display device, and
wherein the performing step comprises transmitting an authority request message to the authentication authority or server, and receiving an authority approval message from the authentication authority or server.
2. The method of claim 1 , wherein the determining step further comprises receiving a position information from the display device, and determining image data to be transmitted to the display device based on positional information of the display device.
3. The method of claim 2 , wherein the controlling step further comprises detecting a change in position of the display device, and transmitting to the display device the image data determined based on the changed position of the display device.
4. A method of displaying an image by using a light source, the method comprising of:
receiving an image data from an external device, the image data comprising at least one of an image or text;
determining a portion of image data to be distributed to one or more display devices based on an interaction with the one or more display devices;
performing an authorization procedure to distribute the image data in response to the display device; and
controlling the distribution of image data as a result of the determining step,
wherein the determining step includes dividing the image data into one or more portions automatically or manually, in consideration of at least one of the number of image data to be generated, the number of the display devices for receiving the image data, and a position of the display device, and
wherein the performing step comprises transmitting an authority request message to the display device, and receiving an authority approval message from the display device.
5. The method of claim 4 , wherein the controlling step controls the distribution of image data to be distributed only to the display device that transmitted the approval message among a plurality of display devices.
