The first resource identification information has a data amount corresponding to an access code of a size that can be displayed on the display. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent Publication No. 2021-22123 Summary of the Invention [Problem to be solved by the invention]

[0004] When the first code information generated based on the first access information for connecting to the first external device is displayed in an area allocated to a part of the display screen, if the first code information becomes too fine, depending on the display performance of that area, the first code information may not be displayed correctly or a malfunction may occur due to the first code information not being able to be read correctly by the terminal device, etc.

[0005] The present disclosure aims to provide an electronic device, an information processing system, and an information display method that can avoid malfunctions such as the first code information not being able to be displayed correctly or the first code information not being able to be read correctly by a terminal device, etc., even if the first area allocated to displaying first code information generated based on first access information does not meet the required performance. [Means for solving the problem]

[0006] The electronic device of the present disclosure includes a display unit, a first acquisition unit, a determination unit, a second acquisition unit, and a display control unit. The display unit has a display screen. The first acquisition unit acquires first access information for connecting to a first external device and first display performance information indicating display performance of a first area allocated to a part of the display screen. The determination unit determines whether the first area satisfies first required performance required to display first code information generated based on the first access information, based on the first display performance information. The second acquisition unit requests the second external device to shorten the first access information, and acquires second access information obtained by shortening the first access information from the second external device. When the determination unit determines that the first area does not satisfy the first required performance, the display control unit displays second code information generated based on the second access information in the first area.

[0007] The information processing system of the present disclosure includes a terminal device and the electronic device described above. The terminal device has an imaging unit, a restoration unit, and a first communication unit. The imaging unit reads the first code information or the second code information displayed in the first area. The restoration unit restores the read first code information or the second code information into access information. The first communication unit connects to the first external device or the second external device based on the restored access information.

[0008] The information processing system of the present disclosure includes the electronic device and the second external device. The second external device includes a shortening unit, a storage unit, a connection transfer unit, an unauthorized connection detection unit, and a control unit. When the shortening of the first access information is requested by the electronic device, the shortening unit shortens the first access information to obtain the second access information, and returns the second access information to the electronic device. The storage unit stores the first access information and the second access information in association with each other. The connection transfer unit transfers a connection from the outside based on the second access information to a connection destination based on the first access information stored in association with the second access information. The unauthorized connection detection unit detects a connection that is highly likely to be unauthorized as a suspect connection. When the suspect connection is detected, the control unit restricts the transfer of a connection from a connection source of the suspect connection by the connection transfer unit.

[0009] The information display method disclosed herein displays information on a display screen, and includes the steps of: acquiring first access information for connecting to a first external device and first display performance information indicating display performance of the first region allocated to a part of the display screen; determining, based on the first display performance information, whether the first region satisfies first required performance required for displaying first code information generated based on the first access information; requesting a second external device to shorten the first access information, acquiring second access information from the second external device in which the first access information has been shortened; and, if it is determined that the first region does not satisfy the first required performance, displaying, in the first region, second code information generated based on the second access information. Effect of the Invention

[0010] According to the present disclosure, even if the first area allocated to display the first code information generated based on the first access information does not meet the required performance, it is possible to avoid problems such as the first code information not being able to be displayed correctly or the first code information not being able to be read correctly by a terminal device, etc. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0012] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present disclosure will now be described with reference to the accompanying drawings, in which the same or corresponding parts in the drawings are designated by the same reference characters and will not be described repeatedly.

[0013] First Embodiment 1.1 Overall configuration of information processing system 1 First, an information processing system 1 including an electronic device 100 will be described with reference to FIGS. 1 to 6. FIG. 1 is a block diagram showing a configuration of an information processing system 1 including an electronic device 100 according to a first embodiment of the present disclosure. FIG. 2 is an explanatory diagram showing a display example when the resolution of the display screen 121 is 4K. FIG. 3 is an explanatory diagram showing an enlarged example of a task tray area RT displayed on the right side of the lower end of the display screen 121. FIG. 4 is an explanatory diagram showing an enlarged example of first code information Q1 displayed near the left end of the task tray area RT. FIG. 5 is an explanatory diagram showing a display example when the resolution of the display screen 121 is full HD. FIG. 6 is an explanatory diagram showing an enlarged example of second code information Q2 displayed near the left end of the task tray area RT.

[0014] As shown in FIG. 1, the information processing system 1 includes a first external device 10, a second external device 20, a terminal device 30, and an electronic device 100. The first external device 10 is an external device that provides various information and services to the electronic device 100 and the terminal device 30. The second external device 20 is an external device that provides a so-called shortened URL (Uniform Resource Locator) service. The terminal device 30 is a device that is operated by a user to access the first external device 10. The first external device 10 will be described in detail in "1.4", the second external device 20 in "1.5", and the terminal device 30 in "1.6".

[0015] 1.2 Configuration of the Electronic Device 100 The electronic device 100 includes a CPU (Central Processing Unit) 110, a display unit 120, a storage unit 130, and a communication unit 140.

[0016] The CPU 110 controls each unit of the electronic device 100. The CPU 110 may be, for example, a processor or a MPU (Micro Processing Unit), but is not limited to these. The CPU 110 has a first acquisition unit 111, a determination unit 112, a second acquisition unit 113, a display control unit 114, and a remote control unit 115.

[0017] For example, if an OS (Operating System, sometimes called "basic software") that runs on the CPU 110 and programs for the functions corresponding to the first acquisition unit 111, the determination unit 112, the second acquisition unit 113, the display control unit 114, and the remote control unit 115 are stored in the storage unit 130, the CPU 110 executes the OS and programs to realize each of the above-mentioned units. Examples of the OS include, but are not limited to, Microsoft Windows (registered trademark) and Android (registered trademark). Each of the above-mentioned units may be composed of, but is not limited to, an electronic circuit, a DSP (Digital Signal Processor), an FPGA (Field Programmable Gate Array), an ASIC (Application Specific Integrated Circuit), or the like.

[0018] The first acquisition unit 111 acquires first access information for connecting to the first external device 10 and first display performance information indicating the display performance of a first area R1 (see Figures 2 and 3) allocated to a portion of the display screen 121.

[0019] The determination unit 112 determines, based on the first display performance information, whether or not the first region R1 satisfies the first required performance required for displaying the first code information Q1 generated based on the first access information.

[0020] The second acquisition unit 113 requests the second external device 20 to shorten the first access information, and acquires from the second external device 20 the second access information resulting from the shortening of the first access information.

[0021] If the determining unit 112 determines that the first region R1 does not satisfy the first required performance, the display control unit 114 causes the second code information Q2 generated based on the second access information to be displayed in the first region R1.

[0022] The remote control unit 115 performs control based on an operation input received from the second communication unit 37 of the terminal device 30. The remote control unit 115 will be described later in "1.6".

[0023] The display unit 120 has a display screen 121. The display unit 120 includes a display unit with and without a memory property. Examples of a display unit with no memory property include, but are not limited to, liquid crystal and organic electro-luminescence (EL). Examples of a display unit with a memory property include, but are not limited to, electronic paper.

[0024] Therefore, if the first region R1 allocated to display the first code information Q1 generated based on the first access information does not satisfy the required performance, the second code information Q2 generated based on the second access information obtained by shortening the first access information is displayed in the first region R1 instead of the first code information Q1. As a result, it is possible to avoid problems such as the first code information Q1 not being able to be displayed correctly or the terminal device 30 not being able to read the first code information Q1 correctly.

[0025] The storage unit 130 stores information and data necessary for controlling each unit of the electronic device 100. The storage unit 130 may store or store an OS, a program, etc. executed by the CPU 110. The storage unit 130 includes a memory, specifically, a volatile memory and a non-volatile memory. The volatile memory includes, for example, a dynamic random access memory (DRAM) and a static random access memory (SRAM), but is not limited to these. The non-volatile memory includes, for example, a read-only member (ROM), a flash memory, a solid state drive (SSD), and a hard disk, but is not limited to these.

[0026] The communication unit 140 is connected to the communication unit 13 of the first external device 10, the communication unit 23 of the second external device 20, and the second communication unit 37 of the terminal device 30 by wire or wirelessly. As a result, the electronic device 100 performs bidirectional communication with the first external device 10, the second external device 20, and the terminal device 30.

[0027] 1.3 Key terms related to display screen 121 Various sizes, resolutions, etc. can be selected as necessary for the display screen 121. Examples of resolutions that are often adopted include "Full HD (High Definition)", i.e., 1,920×1,080=2,073,600 pixels, and "4K", i.e., 3,840×2,160=8,294,400 pixels, but are not limited to these resolutions.

[0028] (Configuration and effect of claim 2) The first display performance information includes, for example, the resolution of the display screen 121 and the size of the first region R1. This is because the number of pixels in the first region R1 is determined by these. Therefore, if the size of the first region R1 changes, this is reflected in the first display performance information. As a result, if the first code information Q1 cannot be displayed correctly in the first region R1 or the terminal device 30 cannot read this first code information Q1 correctly, the second code information Q2 is displayed in the first region R1 instead.

[0029] The resolution of display screen 121 and the size of first region R1 are managed by the OS running on CPU 110. However, the size of first region R1 may be changed by an application running on the OS. For example, when the resolution of display screen 121 is less than 4K (e.g., full HD), the size of first region R1 may be set to 40×40 pixels. When the resolution of display screen 121 is 4K, the size of first region R1 may be set to 80×80 pixels, which is twice as large in both the vertical and horizontal directions.

[0030] Alternatively, the size of the first region R1 may be adjusted so that the size of the first region R1 on the display screen 121 is approximately the same regardless of the resolution of the display screen 121.

[0031] The first access information may include a first URL indicating the location of the first external device 10 on the Internet, and the second access information may include a second URL obtained by shortening the first URL. Therefore, if the first area R1 allocated to display the first code information Q1 generated based on the first URL does not satisfy the required performance, the second code information Q2 generated based on the second URL obtained by shortening the first URL is displayed in the first area R1 instead. As a result, it is possible to avoid problems that may occur when the first code information Q1 is displayed.

[0032] The first code information Q1 and the second code information Q2 may both include a two-dimensional code. An example of a two-dimensional code is a QR code (registered trademark), but is not limited to this. Therefore, a two-dimensional code having a higher information density per area than a one-dimensional barcode is displayed in the first region R1. As a result, more information can be displayed in the first region R1.

[0033] 2 and 5, in electronic device 100, a horizontally long rectangular task tray area RT is disposed on the right side of the lower edge of display screen 121. As shown in Fig. 3, a square first area R1 is allocated to the left edge of this task tray area RT.

[0034] As shown in Fig. 2, when the resolution of the display screen 121 is 4K, if the first region R1 is set to 80 x 80 pixels, the first region R1 satisfies the required performance, and the first code information Q1 (see Fig. 4) is displayed as is. On the other hand, as shown in Fig. 5, when the resolution of the display screen 121 is full HD, if the first region R1 is set to 40 x 40 pixels, the first region R1 does not satisfy the required performance, and the second code information Q2 (see Fig. 6) is displayed instead.

[0035] 1.4 Configuration of the first external device 10 As described above, the first external device 10 is an external device that provides various information, services, and the like to the electronic device 100 and the terminal device 30. Examples of the first external device 10 include, but are not limited to, a Web (World Wide Web) server and a video conference server.

[0036] The first external device 10 includes at least a CPU 11, a storage unit 12, and a communication unit 13. These hardware configurations are similar to those of a general computer used as a server, and therefore detailed description thereof will be omitted.

[0037] 1.5 Configuration of the second external device 20 As described above, the second external device 20 is an external device that provides a so-called shortened URL (Uniform Resource Locator) service. A shortened URL service is a site that converts a long URL into a URL with a shorter notation. If it is sufficient to simply convert a long URL into a short URL, any of various existing shortened URL services provided to the general public free of charge or for a fee may be selected and used.

[0038] The second external device 20 includes a CPU 21, a storage unit 22, and a communication unit 23. The hardware configuration of these is similar to that of a general computer for a server, and therefore detailed description is omitted. The CPU 21 includes a shortening unit 21a, a connection forwarding unit 21b, and an unauthorized connection detection unit 21c. If a program for each function corresponding to each of these units is stored in the storage unit 22, the CPU 21 executes the program to realize each of the above units.

[0039] When the shortening unit 21a is requested by the electronic device 100 to shorten the first access information, the shortening unit 21a shortens the first access information to obtain second access information, and returns the second access information to the electronic device 100.

[0040] The storage unit 22 stores the first access information and the second access information in association with each other.

[0041] The connection forwarding unit 21b forwards an external connection based on the second access information to a connection destination based on the first access information that is stored in association with the second access information.

[0042] The unauthorized connection detection unit 21c detects a connection that is highly likely to be unauthorized as a suspect connection. A well-known method may be applied to detect a connection that is highly likely to be unauthorized.

[0043] When a suspicious connection is detected, the CPU 21 restricts the transfer of a connection from the source of the suspicious connection by the connection transfer unit 21b.

[0044] Therefore, when the second external device 20 detects a connection that is likely to be fraudulent, it restricts the transfer of the connection from that connection source. As a result, it is possible to provide an information processing system that is highly resistant to security risks such as brute force attacks.

[0045] The CPU 21 deletes from the storage unit 22 the invalidated first access information and the second access information that is stored in association with the first access information.

[0046] This prevents the invalidated first access information and the associated second access information from remaining for a long period of time, thereby making it possible to provide an information processing system that is more resistant to security risks.

[0047] 1.6 Configuration of terminal device 30 As described above, the terminal device 30 is a device operated by a user to access the first external device 10. Examples of the terminal device 30 include, but are not limited to, a smartphone or a tablet.

[0048] The terminal device 30 includes a CPU 31, an imaging unit 32, an operation unit 33, a display unit 34, a storage unit 35, a first communication unit 36, and a second communication unit 37. These hardware configurations are similar to those of general smartphones, tablets, etc., and therefore detailed explanations are omitted. The CPU 31 includes a restoration unit 31a. If a program of a function corresponding to this restoration unit 31a is stored in the storage unit 35, the restoration unit 31a is realized by the CPU 31 executing the program.

[0049] The imaging unit 32 reads the first code information Q1 or the second code information Q2 displayed in the first region R1. The imaging unit 32 may be, for example, a built-in camera, but is not limited to this.

[0050] The restoration unit 31a restores the read first code information Q1 or second code information Q2 into access information.

[0051] The first communication unit 36 ​​connects to the first external device 10 or the second external device 20 based on the restored access information.

[0052] Therefore, when the second code information Q2 is displayed in the first area R1, the terminal device 30 reads the second code information Q2 and connects to the second external device 20 based on the restored access information, which is then transferred to the first external device 10. As a result, even if the display performance of the first area R1 is insufficient, the terminal device 30 can connect to the first external device 10 without any problems.

[0053] The operation unit 33 receives an operation input. Examples of the operation unit 33 include, but are not limited to, a button, a keyboard, and a touch panel that allows touch operations.

[0054] Examples of the display unit 34 include, but are not limited to, liquid crystal and organic electroluminescence (EL). The display unit 34 may be a touch panel that allows touch operations and the like, and may also serve as the operation unit 33.

[0055] The second communication unit 37 transmits the operation input received by the operation unit 33 to the electronic device 100.

[0056] As described above, the remote control unit 115 of the electronic device 100 performs control based on the operation input received from the second communication unit 37. Therefore, the electronic device receives the operation input accepted by the terminal device and performs control based on the operation input. As a result, the terminal device can remotely control the electronic device.

[0057] 1.7 Information Display Method Using Electronic Device 100 Next, an overview of an information display method for displaying information on the display screen 121 of the electronic device 100 will be described with reference to Fig. 7. Fig. 7 is a flowchart showing the information display method by the electronic device 100.

[0058] As shown in FIG. 7, first, in step S1, the first acquisition unit 111 acquires first access information for connecting to the first external device 10 and first display performance information indicating the display performance of the first area R1 allocated to a portion of the display screen 121.

[0059] In step S2, the determination unit 112 determines whether the first region R1 satisfies the first required performance required for displaying the first code information generated based on the first access information, based on the first display performance information. If the first region R1 satisfies the first required performance, the process proceeds to step S5, and if not, the process proceeds to step S3.

[0060] In step S3, the second acquisition unit 113 requests the second external device 20 to shorten the first access information, and acquires from the second external device 20 the second access information resulting from the shortening of the first access information.

[0061] In step S4, the display control unit 114 displays the second code information Q2 generated based on the second access information in the first area R1, and then ends the series of processes.

[0062] On the other hand, in step S5, the display control unit 114 displays the first code information Q1 generated based on the first access information in the first region R1, and then ends the series of processes.

[0063] Therefore, if the first region R1 allocated to display the first code information Q1 generated based on the first access information does not satisfy the required performance, the second code information Q2 generated based on the second access information obtained by shortening the first access information is displayed in the first region R1 instead of the first code information Q1. As a result, it is possible to avoid problems such as the first code information Q1 not being able to be displayed correctly or the terminal device 30 not being able to read the first code information Q1 correctly.

[0064] <Second embodiment> Next, a method of holding an electronic conference using the electronic device 100 with an application for an electronic conference running as a second embodiment will be described with reference to Fig. 8. Fig. 8 is an explanatory diagram of a method of holding an electronic conference using the electronic device 100 according to the second embodiment of the present disclosure. Note that the configuration of this second embodiment is the same as the configuration of the first embodiment shown in Fig. 1.

[0065] 8, when an application for electronic conferences is started in the electronic device 100 and a specific date is specified, a list 122 of electronic conferences for that date is displayed on the display screen 121. Here, three electronic conferences are displayed.

[0066] When one of the displayed electronic conferences is selected (the top electronic conference 122a enclosed in a frame is selected in FIG. 8), options for participating in the selected electronic conference 122a are displayed below the electronic conference list display 122. These options include a button 123 that can be tapped with a fingertip or the like on the display screen 121, and first code information Q1 displayed in a second area R2 located to the right of the button 123.

[0067] At this time, the first acquisition unit 111 acquires conference information of one or more electronic conferences, and also acquires second display performance information indicating the display performance of a second region R2 allocated to a part of the display screen 121 for each electronic conference in the conference information list display 122. This conference information includes the first access information.

[0068] The determination unit 112 determines whether the second region R2 satisfies the second required performance required for displaying the first code information Q1 in the second region R2 based on the second display performance information. If it is determined that the second region R2 does not satisfy the second required performance, the display control unit 114 displays the second code information Q2 in the second region R2.

[0069] Therefore, if the second area R2 allocated for the list display 122 of the conference information including the first code information Q1 does not satisfy the required performance, the second code information Q2 is displayed instead of the first code information Q1. As a result, it is possible to avoid problems that may occur when the first code information Q1 is displayed as it is.

[0070] On the other hand, if it is determined that the second region R2 satisfies the second required performance, the display control unit 114 causes the first code information Q1 to be displayed in the second region R2.

[0071] In addition, the first acquisition unit 111 may acquire third display performance information indicating the display performance of a third area allocated to a part of the display screen 121 for displaying the first code information Q1 and a file icon of the started conference.

[0072] In this case, the determination unit 112 determines whether the third region satisfies the third required performance required for displaying the first code information Q1 in the third region based on the third display performance information. If it is determined that the third region does not satisfy the third required performance, the display control unit 114 displays the second code information Q2 in the third region.

[0073] Therefore, if the third area allocated to display the first code information Q1 and the file icon of the started conference does not meet the required performance, the second code information Q2 is displayed instead of the first code information Q1. As a result, it is possible to avoid problems that may occur when the first code information Q1 is displayed.

[0074] The present invention can be implemented in various other forms without departing from its spirit or main features. Therefore, the above-described embodiments are merely illustrative in all respects and should not be interpreted as being limiting. The scope of the present invention is defined by the claims and is not limited to the text of the specification. Furthermore, all modifications and changes within the equivalent scope of the claims are within the scope of the present invention. [Industrial Applicability]
