Abstract
A display device includes imaging unit (101) to generate a captured image, image recognizer (102) to recognize whether or not the captured image contains a reception terminal, light emitter (106) to emit light in accordance with a modulation signal, and transmission controller (103) and light emission controller (105) to control driving of light emitter (106) based on a result recognized by image recognizer (102).
Claims6
A display device configured to display an image captured by a camera of a reception terminal, the display device comprising:
- a display including a light emitter configured to transmit an optical modulation signal, the optical modulation signal being transmitted by the light emitter emitting light in accordance with a pulse train obtained by modulating predetermined data;
- and
- a controller that controls output to the display to let a specific image be output to the display during transmission of the optical modulation signal by the light emitter,
- wherein the specific image includes a middle zone and a peripheral zone,
- the middle zone of the specific image is output at a position corresponding to a direction of the camera of the reception terminal, such that the camera of the reception terminal can image the middle zone, and
- the light emitter is configured to transmit the optical modulation signal such that (i) the optical modulation signal is transmitted to the reception terminal, which images the middle zone of the specific image, and (ii) the optical modulation signal is not transmitted to another reception terminal, which does not image the middle zone of the specific image.
