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.

Abstract: An apparatus includes a processor and a recording medium having a program, the program causing the processor to execute operations. The operations include providing a normal mode and a visible light communication mode, wherein the normal mode and the visible light communication mode are switchable. In the normal mode, first image data is obtained by image capture with a first exposure time by sequentially starting exposure for a plurality of exposure lines in an image sensor each at a different time and each of the plurality of exposure lines partially overlaps in exposure time an adjacent exposure line. In the visible light communication mode, (i) a second exposure time of the image sensor is set, (ii) a bright line image is obtained, and (iii) information is obtained by demodulating data specified by a pattern of the plurality of bright lines included in the obtained bright line image.

Abstract: An information processing program causes a computer to execute: encoding information to be transmitted, to determine a luminance change frequency; and outputting a signal of the determined luminance change frequency to cause a light emitter to change in luminance according to the determined luminance change frequency to transmit the information. In the encoding, each of a first frequency and a second frequency different from the first frequency is determined as the luminance change frequency. In the outputting, each of a signal of the first frequency and a signal of the second frequency is output as the signal of the determined luminance change frequency, to cause the light emitter to change in luminance according to the first frequency during a first time and change in luminance according to the second frequency during a second time different from the first time after the first time elapses.

Abstract: An information communication method is provided that includes continuously capturing an image of a subject that transmits a signal by changing luminance, with an image sensor. The method also includes displaying a captured image that includes a box and a subject image for identifying the subject, while continuously updating a position of the subject image on the captured image, according to a positional relationship between the image sensor and the subject established when the image of the subject is captured. The method further includes determining whether the subject image is in the box, and receiving the signal transmitted by the subject when it is determined that the subject image is in the box. In the receiving, information is obtained by demodulating a bright line pattern that appears in a second image data and corresponds to the plurality of exposure lines.

Abstract: A video display method is provided that displays, on a per frame basis, an image included in a video signal. The method includes generating a first visible light communication image by encoding a visible light communication signal, the first visible light communication image being an image having a stripe pattern for visible light communication, and displaying, in a predetermined frame, the image included in the video signal. The method also includes switching a pitch of the first visible light communication image to a different pitch, and generating a second visible light communication image. The method further includes displaying the second visible light communication image that has a stripe pattern configured with a different minimum pitch, which is different in resolution from the stripe pattern of the first visible light communication image.
