The information display device according to claim 1 or 2, wherein the display control unit controls the display unit to display a message on the screen prompting the user to hold the mobile terminal towards the display unit.
The information display device according to claim 1 or claim 2, wherein the information code includes a QR code.
The imaging step involves capturing images of the surroundings to obtain image data, A detection step that detects, based on the image data acquired in the aforementioned imaging step, that a person has performed an action of holding the mobile device towards the display unit, An information display method comprising: a display control step that controls the display unit to display an information code on the screen when it is detected in the detection step that the person has performed the action of holding the mobile terminal toward the display unit.

Description

This disclosure relates to an information display device and information display method for displaying content, and more particularly to an information display device and information display method for displaying a two-dimensional code along with content such as advertisements. Patent Document 1 describes a product and store information provision system consisting of a display device, a mobile phone, and a management computer. This display device is installed near the product sales area or inside the store and has a liquid crystal display that displays barcodes containing link information to websites related to the products and stores, along with advertising videos for the products and stores. Japanese Patent Publication No. 2008-256950 This is an explanatory diagram of an information display system 100 comprising a digital signage 200 and a content distribution server 300 according to one embodiment of the present disclosure.This is a block diagram showing the electrical configuration of the information display system 100.This is an explanatory diagram illustrating the action of a person 30, which is the target of detection by the digital signage 200, holding a smartphone 40 towards the display 220.This is a flowchart of the basic operation controlled by the CPU 230 of the digital signage 200.This is an explanatory diagram illustrating the display under normal conditions.This is an explanatory diagram illustrating a method of displaying a QR code 60 overlaid on content that was previously displayed.This is an explanatory diagram illustrating a configuration in which the previously displayed content is temporarily hidden and only the QR code 60 is displayed.This is an explanatory diagram illustrating an example of how the display position of the QR code 60 is changed according to the location of the detected person 30 or smartphone 40.This is an explanatory diagram illustrating an example of how the display position of the QR code 60 is changed in accordance with changes in the position of the detected person 30 or smartphone 40.This is an explanatory diagram illustrating an example of how the display size of the QR code 60 is changed according to the distance to the detected person 30 or smartphone 40.This is an explanatory diagram illustrating an example of how the display shape of the QR code 60 is corrected according to the position (direction) of the detected person 30 or smartphone 40.This is an explanatory diagram illustrating an example of how the content of the QR code 60 is changed according to the attributes of the detected person 30.This is an explanatory diagram illustrating an example of a configuration in which the fact that the digital signage 200 has the functions described herein is displayed on a pop-up display 51 placed on top of the digital signage 200.This is an explanatory diagram illustrating an example of how the digital signage 200 has the functions described herein, as indicated by the ticker 52 on the display 220. Embodiments of this disclosure will be described with reference to the drawings. Note that in the drawings, the same or corresponding parts will be denoted by the same reference numerals and will not be repeated in the description. (1) Outline configuration of the digital signage 200 Figure 1 is an explanatory diagram of an information display system 100 consisting of a digital signage 200 and a content distribution server 300 according to one embodiment of the present disclosure. Figure 2 is a block diagram showing the electrical configuration of this information display system 100. Note that the digital signage 200 is an example of the "information display device" of the present disclosure. As shown in Figures 1 and 2, the digital signage 200 comprises a camera 210, a display 220, a CPU 230, a volatile main memory unit 240, a non-volatile auxiliary memory unit 250, a communication unit 260, a USB terminal 270, and a data bus 280 that interconnects these components. However, to enable high-speed access, the CPU (Central Processing Unit) 230 and the main memory unit 240 are directly connected. The camera 210 (corresponding to the "imaging unit" in this disclosure) is positioned at a location suitable for imaging the area around the digital signage 200, for example, at the upper end of the digital signage 200. The display 220 (corresponding to the "display unit" in this disclosure) displays content such as advertisements and maps (such as tourist information and floor guides), and related two-dimensional codes such as QR codes (corresponding to the "information code" in this disclosure).
