Embodiment approach 1

[0612] Embodiment 1 will be described below.

[0613] (Observation of brightness of light emitting part)

[0614] There is proposed an imaging method that does not expose all imaging elements at the same timing when capturing one image, but starts and ends exposure at different timings for each imaging element. figure 1 This is an example in which the imaging elements arranged in one row are simultaneously exposed, and the exposure start timings are shifted in the order of the row from the closest to the farthest, and images are taken. Here, it is called an exposure line of an imaging element exposed at the same time, and a line of pixels on an image corresponding to the imaging element is called a bright line.

[0615] When using this imaging method to image a flashing light source on the entire surface of the imaging element, as in figure 2 In this way, bright lines (lines of brightness and darkness of pixel values) along the exposure line appear on the captured image. B...

Embodiment approach 2

[1004] (Application to ITS)

[1005] Hereinafter, an ITS (Intelligent Transport Systems: intelligent transportation system) will be described as an application example of the present invention. In this embodiment, high-speed communication of visible light communication is realized, and application to the ITS field can be realized.

[1006] Figure 91 It is a diagram explaining communication between a transportation system equipped with a visible light communication function and vehicles or pedestrians. The traffic signal 6003 is equipped with the visible light communication function of this embodiment, and can communicate with the vehicle 6001 and the pedestrian 6002 .

[1007] Information transmission from the vehicle 6001, the pedestrian 6002, and the traffic signal 6003 is performed by a headlight or a flash light emitting unit of a portable terminal held by the pedestrian. The information transmission from the signal 6003 to the vehicle 6001 and the pedestrian 6002 is i...

Embodiment approach 3

[1047] (Service provision example)

[1048] Hereinafter, in this embodiment, as an application example of the present invention, use Figure 97 An example of service provision to users will be described. Figure 97 It is a diagram for explaining an example of providing a service to a user according to the third embodiment. exist Figure 97 In , a web server 4000a, transmitters 4000b, 4000d, 4000e, receivers 4000c, 4000f, and a building 4000g are shown.

[1049] Receivers 4000c and 4000f receive signals from a plurality of transmitters 4000b, 4000d and 4000e located inside and outside the home, and process them to provide services to users. In addition, the transmitter and the receiver may be able to independently process signals and provide services to users, or may be able to cooperate with the network server 4000a constituting the network to change their operations and transmitted signals according to instructions from the network. While providing services to users.

Abstract

An information communication method which enables communication using a variety of devices includes: a step (SK61) in which positional information indicating a position of a terminal device is transmitted; a step (SK62) in which identification information of at least one device, and service information associated with each piece of identification information are acquired and stored; a step (SK63) in which a light-exposure time for an image sensor is set; a step (SK64) in which a bright-line image, i.e. an image including a plurality of bright lines, is acquired; a step (SK65) in which identification information of an object is acquired by demodulating data identified by patterns of the plurality of bright lines included in the acquired bright-line image; and a step (SK66) in which service information associated with the identification information of the object is selected from among the at least one piece of service information stored in step (SK62), and said service information is presented to a user.

Description

technical field [0001] The present invention relates to a communication method between portable terminals such as smartphones, tablet PCs, and mobile phones, and home appliances such as air conditioners, lighting equipment, and rice cookers. Background technique [0002] In the home network in recent years, in addition to cooperation of AV home appliances by IP (Internet Protocol) connection under Ethernet (registered trademark) or wireless LAN (Local Area Network), there is also power consumption corresponding to environmental problems The home energy management system (HEMS), which has functions such as energy management and power ON / OFF outside the house, is in progress. The introduction of home appliance cooperation functions that realize various home appliances are connected to the network. However, there are also home appliances with insufficient computing power in terms of having a communication function, or home appliances in which it is difficult to implement a comm...
