Abstract: A portable terminal detects a color change region corresponding to a marker in frames, and determines whether the brightness and/or hue change with time in the color change region matches a search rule. Subsequently, when the brightness and/or hue change with time in the color change region matches a search rule, the portable terminal restores information by decoding and determines whether the information is the content of predetermined information corresponding to the search rule determined to match. Furthermore, when the restored information is the content of predetermined information corresponding to the search rule determined to match, the portable terminal displays the information in association with the color change region to provide notice that the corresponding flying object is an appropriate flying object performing optical communication.

Abstract: To easily capture the light emission position of a light-emitting apparatus on the imaging apparatus side, even when the positional relationship of the two changes. A mobile device detects its own speed, and an LED within the mobile device accomplishes light emission in accordance with any out of a first light emission pattern, a second light emission pattern and a third light emission pattern so that the light emission cycle becomes shorter the faster the speed of the mobile device. On the other hand, a server detects the speed of the mobile device from frames obtained through imaging by an imager, and changes the imaging interval of the imager so that the imaging interval becomes longer the slower the speed.

Abstract: A reception device acquires multiple frames for a period corresponding to an optical signal format and determines whether a color change region within the frames includes any of red (R), green (G), and blue (B), which is a first color, and black (Bk) in the non-emission period corresponding to a header, which is a second color. Moreover, when the color change region within the multiple frames for a period corresponding to an optical signal format includes any of red (R), green (G), and blue (B) and black (Bk), the reception device controls decoding of a bit data string corresponding to the red (R), green (G), and blue (B) colors in the color change region to acquire communication target information.

Abstract: The imager and controller of an information apparatus images the back face of another information apparatus to acquire the manufacturing number of the other information apparatus corresponding to the two-dimensional bar code provided on the back face of the other information apparatus and acquire visible light information corresponding to blinking of light emitted by the light emitter arranged on the back face of the other information apparatus. Furthermore, the controller controls the imager so as to be able to image the two-dimensional bar code and the light emitted by the light emitter.
