Embodiment approach 1

[0114] Figure 6 An example of the configuration of the device 100 and the terminal 150 in this embodiment is shown.

[0115] [Configuration of device 100]

[0116] The device 100 (corresponding to a visible light communication transmitter) includes a visible light source such as an LED (Light Emitting Diode), lighting, or a lamp (may also be collectively referred to as a light source). In addition, the device 100 will be referred to as a "first device" hereinafter.

[0117] exist Figure 6 In the first device 100, the transmitting unit 102 inputs, for example, information 101 related to a location or a location. Furthermore, the transmitting unit 102 may input the information 105 related to the time. Furthermore, the transmitting unit 102 may input both the information 101 about the location or the position, and the information 105 about the time.

[0118] Transmitter 102 receives location-related information or position-related information 101 and / or time-related inform...

Embodiment approach 2

[0150] In this embodiment, a case where there are a plurality of first devices 100 described in Embodiment 1 will be described.

[0151] In this embodiment, for example Figure 8 shown, with Figure 6 The shown first device 100 is a modulated signal transmitted by the similarly configured 1-1 device 301-1. have with Figure 6 The terminal 150 shown has the same structure as the terminal 302 that receives the modulated signal sent by the 1-1 device 301-1, for example, obtains information related to the 1-1 location and / or position, and information related to the 1-1 moment. Information.

[0152] Likewise, with Figure 6 The illustrated first device 100 has a modulated signal transmitted by the first-second device 301-2 having the same configuration. The terminal 302 receives the modulated signal sent by the 1-2 device 301-2, for example, obtains information related to the 1-2 place and / or position, and information related to the 1-2 time.

[0153] Then, the terminal 302 c...

Embodiment approach 3

[0162] Figure 9 An example of the configuration of the base station 470 (or AP (access point)) that communicates with the device 400, the terminal 450, and the terminal 450 in this embodiment is shown.

[0163] The device 400 includes, for example, a visible light source such as LED, lighting, a light source, or a lamp. In addition, the device 400 is also called "the 1st device" below.

[0164] In addition, in Figure 9 As shown in the first device 400, for the Figure 6 The configurations of the first device 100 shown that perform the same operations are assigned the same symbols. and, in Figure 9 terminal 450 shown, for use with Figure 6 Components of the illustrated terminal 150 performing the same operations are assigned the same symbols.

[0165] exist Figure 9 In the first device 400, the transmission unit 102 inputs, for example, information 101 on location or location, information 401-1 on SSID (service set identifier) ​​that is an identifier of the base sta...

Abstract

A reception device (150) capable of safely obtaining information is provided with: an image sensor (A3103) which acquires an image by photography; and reception units (A2053_1-A2053_M) which, with respect to each of N (N is an integer of two or more) regions included in an imaging surface of the image sensor (A3103), sample a plurality of pixels included in the region, and thereby receive mutuallydifferent N optical signals in parallel that are transmitted from a plurality of light sources.

Description

technical field [0001] The present application relates to a receiving device and a receiving method. Background technique [0002] For the purpose of using services based on the location of the terminal, there is a method of using GPS (Global Positioning System) as a method of obtaining information such as the location of the terminal itself. In the method using GPS, the terminal receives a modulated signal sent from a satellite, and estimates its own position by performing position measurement calculations. However, when it is difficult for the terminal to receive radio waves transmitted from satellites (for example, indoors), it is difficult for the terminal to estimate its own position. [0003] In this case, as a method for the terminal to estimate its own position, for example, as shown in the method disclosed in Non-Patent Document 1, the terminal uses a wireless access point (AP (access point)) from a wireless LAN (Local Area Network) The transmitted radio waves are...
