In the determining a pattern, the pattern of the change in luminance is determined by adjusting a first time from one change in luminance to a next change in luminance according to the signal, the one change in luminance and the next change in luminance being a same one of a rise and a fall in luminance. | 08-13-2015 |
20150244914 | INFORMATION COMMUNICATION METHOD - An information communication method is provided for obtaining information from a subject using a terminal device. The method includes obtaining and holding identification information of devices, and service information associated with the identification information, from a server. The method also includes setting an exposure time of an image sensor so that a bright line corresponding to each of the plurality of exposure lines included in the image sensor appears according to a change in luminance of the subject, and obtaining a bright line image including a plurality of bright lines. The method further includes obtaining identification information of the subject, by demodulating data specified by a pattern of the plurality of bright lines included in the obtained bright line image, selecting service information associated with the identification information, and presenting the service information to a user of the terminal device. | 08-27-2015 |
20150244919 | INFORMATION COMMUNICATION METHOD - An information communication method is provided that includes setting an exposure time of an image sensor so that, in an image obtained by capturing a subject by the image sensor, a plurality of bright lines corresponding to a plurality of exposure lines included in the image sensor appear according to a change in luminance of the subject. The method also includes obtaining a bright line image including the plurality of bright lines, by capturing the subject changing in luminance by the image sensor with the set exposure time, and obtaining information by demodulating data specified by a pattern of the plurality of bright lines included in the obtained bright line image. | 08-27-2015 |
20150310736 | COMMUNICATION DEVICE - A mobile device includes a position sensing unit, a remote control information obtainment unit, and a storage unit. Position information obtained by the position sensing unit is stored in the storage unit in association with remote control information. The mobile device further includes a directional space obtainment unit and an apparatus specification unit. The mobile device recognizes a direction pointed by a user using the mobile device, and enables operation of a terminal apparatus existing in the pointing direction. | 10-29-2015 |
20150341539 | INFORMATION COMMUNICATION METHOD - An information communication method is provided for obtaining information from a subject. The information communication method includes transmitting position information indicating a position of an image sensor used to capture the subject, and receiving an ID list that is associated with the position indicated by the position information. The information communication method also includes setting an exposure time of the image sensor so that in a bright line corresponding to an exposure line included in the image sensor appears according to a change in luminance of the subject. The information communication method further includes obtaining a bright line image including the bright line, obtaining information by demodulating data specified by a cycle length or frequency of a stripe pattern of the bright line included in the obtained bright line image, and searching the ID list for identification information that includes the obtained information. | 11-26-2015 |
