Embodiment approach 1

[0433] Embodiment 1 will be described below.

[0434] (Observation of brightness of light emitting part)

[0435] 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 row of pixels on an image corresponding to the imaging element is called a bright line.

[0436] In the case of imaging a flickering light source on the entire surface of the imaging element using this imaging method, if figure 2 In this way, bright lines (lines of brightness and darkness of pixel values) along the exposure line are generated on the captur...

Embodiment approach 2

[0469] In this embodiment, each application example using a receiver such as a smartphone as the information communication device K90 of the first embodiment and a transmitter that transmits information as a blinking pattern of a light source such as LED and / or organic EL will be described.

[0470] In the following description, the normal photography mode or photography in the normal photography mode is called normal photography, and the visible light communication mode or photography in the visible light communication mode is called visible light photography (visible light communication). In addition, intermediate mode imaging may be used instead of normal imaging and visible light imaging, and intermediate images may be used instead of composite images described later.

[0471] Figure 7 It is a diagram showing an example of the imaging operation of the receiver of the present embodiment.

[0472] The receiver 8000 switches between shooting modes such as normal shooting, v...

Embodiment approach 3

[0547] In this embodiment, each application example using a receiver such as a smartphone and a transmitter that transmits information as a blinking pattern of LED or organic EL in the above-mentioned Embodiment 1 or 2 will be described.

[0548] Figure 26 It is a diagram showing an example of the processing operations of the receiver, the transmitter, and the server according to the third embodiment.

[0549] For example, the receiver 8142 configured as a smartphone acquires position information indicating its own position, and transmits the position information to the server 8141 . In addition, the receiver 8142 acquires position information when receiving other signals, for example, using GPS or the like. The server 8141 transmits to the receiver 8142 a list of IDs associated with the positions indicated by the position information. In the ID list, for each ID such as "abcd", the ID and information associated with the ID are included.

[0550] The receiver 8142 receives...

Abstract

A transmission method comprises the steps of: a determination step (S571) for determining a pattern of luminosity change by modulating a signal, and a transmission step (S572) for transmitting a visible-light signal by changing the luminance of a red color represented by a light source in accordance with the determined pattern. The visible-light signal includes data, a preamble, and a payload. A first and a second luminance value appear along a time base in the data, and the first and second luminance values appear alternately along the time base in the payload, the duration of time in which each of the first and second luminance values continues is larger than a first prescribed value and is determined in accordance with the signal and a prescribed scheme.

Description

technical field [0001] The present invention relates to a transmission method, a transmission device, a program, and the like of a visible light signal. Background technique [0002] In the home network in recent years, in addition to the cooperation of AV home appliances by IP (Internet Protocol) connection under Ethernet (registered trademark) or wireless LAN (Local Area Network), there is also a power consumption corresponding to environmental problems. The home energy management system (HEMS) that has functions such as power ON / OFF from outside the house promotes the introduction of a home appliance collaboration function that connects various home appliances 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 communication function in terms of cost. [0003] In order to solve such a problem, Patent Document 1 describes that in an...
