Abstract: An information communication method selectively obtains a location of a terminal device. Determining the location of the terminal device by wireless communication with a wireless access point includes receiving a radio signal including a first identification information to identify a location of the wireless access point, and calculating the location of the terminal device using the identified location of the wireless access point, which is identified by the first identification information. Determining the location of the terminal device by visible light communication with a subject provides higher accuracy and includes setting an exposure time of an image sensor having a plurality to exposure lines 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, obtaining a bright line image by capturing the subject, and demodulating data from the bright line image.

Abstract: A method includes capturing images with an image sensor while switching the shutter speed of the image sensor between a first speed and a second, higher speed. When a captured subject is a barcode, a barcode image is obtained when the shutter speed is the first speed, and barcode information is obtained by decoding the barcode in the image. When a captured subject is a light source, a bright line image including bright lines corresponding to a plurality of exposure lines included in the image sensor is obtained when the shutter speed is the second speed, and a visible light signal is obtained as visible light information by decoding a pattern of the bright lines in the obtained bright line image. The method also includes displaying an image obtained through capturing performed when the shutter speed is the first speed.
