[0029] <First embodiment>

[0030] Figure 1A and 1B 1 is a perspective view illustrating the appearance of a mobile phone device 100A according to the first embodiment of the present disclosure. Mobile phone device 100A according to this embodiment is a smartphone. Note that mobile phone device 100A may be a mobile phone other than a smartphone, or may be a portable information processing device with a call function. Furthermore, in the following description, it is assumed that a first user uses mobile phone device 100A to communicate with a second user, who is the user of another telephone device.

[0031] like Figure 1A and Figure 1BAs shown in the diagram, the mobile phone device 100A includes housings 41 and 42 and a hinge 49. Each of the housings 41 and 42 is a housing in the shape of a rectangular parallelepiped plate. The housing 41 has a rectangular display surface 41S on one of its front and rear surfaces, while the housing 42 has a rectangular display surface 42S on one of its front and rear surfaces. The display surfaces 41S and 42S are display surfaces of the display device 14 included in the mobile phone device 100A (see FIG. Figure 2 In this embodiment, display surfaces 41S and 42S have the same display area. In addition, housing 41 is provided with speaker 16 and microphone 17. For example, when a first user uses mobile phone device 100A to talk with a second user, speaker 16 and microphone 17 are used.

[0032] End surface 41E is one of the two end surfaces on the long sides of the front and rear surfaces of housing 41, among the four end surfaces. Similarly, housing 42 has four rectangular end surfaces surrounding its front and rear surfaces. End surface 42E is one of the two end surfaces on the long sides of the front and rear surfaces of housing 42, among the four end surfaces. Hinge 49 is a so-called hinge that rotatably connects housings 41 and 42. Hinge 49 connects the long side opposite the long side facing display surface 41S at end surface 41E and the long side opposite the long side facing display surface 42S at end surface 42E.

[0033] In this embodiment, the hinge angle formed by the display surfaces 41S and 42S changes with the rotation of the hinge 49. In this embodiment, by setting the hinge angle to 360°, as shown in FIG. Figure 1A With the display surfaces 42S and 41S facing outward as shown in the diagram, the first user can make the display state of the display device 14 of the mobile phone device 100A enter the first display state in which only the display surface 41S is displayed. In addition, by setting the hinge angle to 180°, the first user can Figure 1B As shown in the diagram, the display surfaces 41S and 42S are positioned facing the first user. With this operation, the display state of the display device 14 of the mobile phone device 100A changes to the second display state in which display is performed on both the display surfaces 41S and 42S. The display area in the second display state is larger than the display area in the first display state.

[0034] Figure 2 1 is a block diagram illustrating the hardware configuration of the mobile phone device 100A. Figure 2As shown in the diagram, mobile phone device 100A is a computer that includes a processing device 11, a storage device 12, a communication device 13, a display device 14, an operating device 15, a speaker 16, a microphone 17, and an open / close detection device 18. The various components of mobile phone device 100A are interconnected via a single bus or multiple buses. Note that the term "device" in this application can be replaced with other terms such as circuit, device, or unit. In addition, each component of mobile phone device 100A may include one or more devices, and some components of mobile phone device 100A may be omitted.

[0035] The processing device 11 is a processor that controls the entire mobile phone device 100A and includes, for example, one or more chips. The processing device 11 includes, for example, a central processing unit (CPU) that includes interfaces with peripheral devices, arithmetic devices, registers, and the like. Some or all of the functions of the processing device 11 may be implemented by hardware such as a digital signal processor (DSP), an application-specific integrated circuit (ASIC), a programmable logic device (PLD), or a field-programmable gate array (FPGA). The processing device 11 performs various processes in parallel or sequentially.

[0036] The storage device 12 is a recording medium readable by the processing device 11, and stores a plurality of programs to be executed by the processing device 11 and various data to be used by the processing device 11. The plurality of programs includes a control program PR. The various data includes a table TBL. The storage device 12 includes, for example, a nonvolatile storage circuit such as a read-only memory (ROM), an erasable programmable ROM (EPROM), or an electrically erasable programmable ROM (EEPROM), and a volatile storage circuit such as a random access memory (RAM).

[0037] Figure 3 1 is an explanatory diagram illustrating the storage contents of the table TBL. The table TBL stores so-called phone book data. Figure 3 As shown in the diagram, table TBL stores multiple records r. Each record r is a set of phone numbers and names. Names include nicknames, given names, and titles. Names include "given name," "surname," "given name," "company name," "trade name," and "facility name."

[0038] The communication device 13 is a device that communicates with other devices via a communication network such as a mobile communication network or the Internet. For example, the communication device 13 is also called a network device, a network controller, a network card, or a communication module. For example, the application program received by the communication device 13 from a distribution server (not shown) via the communication network is stored in the storage device 12. In addition, the communication device 13 includes a wireless device that performs short-range wireless communication such as Bluetooth (registered trademark). In addition, the communication device 13 outputs communication information indicating the communication status to the processing device 11. The communication status includes a call initiated to another telephone device, an incoming call from another telephone device, and communication establishment with another telephone device.

[0039] The display device 14 displays various images on the display surfaces 41S and 42S described above under the control of the processing device 11. For example, various display panels such as liquid crystal display panels and organic EL display panels are suitable for use as the display device 14. The display device having the display surface 41S and the display device having the display surface 42S are physically separate display devices. However, in the mobile phone device 100A according to this embodiment, a single image can be displayed across the display surfaces 41S and 42S, or the display on the display surface 41S and the display on the display surface 42S can be linked to each other to perform a combined process. Thus, in this embodiment, the display device having the display surface 41S and the display device having the display surface 42S are considered to be a single display device 14.

[0040] In addition, the display device 14 can switch the display state between a first display state and a second display state. In the second display state, the display area is larger than the display area in the first display state.

[0041] The operation device 15 is a device for inputting information to be used by the mobile phone device 100A. The operation device 15 receives user operations. Specifically, the operation device 15 receives operations for inputting symbols such as numbers and letters, and for selecting icons to be displayed on the display device 14. For example, a touch panel that detects contact with the display surface of the display device 14 is suitable as the operation device 15. Note that the operation device 15 may include multiple operators that can be operated by the user. A first user can use the operation device 15 to input the telephone number of another telephone device used by a second user.

[0042] The speaker 16 is a device that converts an electrical signal into sound. The processing device 11 includes a DA converter, and the analog signal obtained by converting the digital signal using the DA converter is supplied to the speaker 16. Alternatively, a DA converter may be provided in the front stage of the speaker 16. In this case, the processing device 11 outputs the audio data to the DA converter. When the first user uses the mobile phone device 100A to talk to the second user, the speaker 16 outputs the second user's voice. Figure 1A In the example illustrated in FIG, speaker 16 is provided above display device 14, but the present disclosure is not limited thereto. For example, a first speaker may be provided above display device 14, and a second speaker may be provided below display device 14. When two speakers are provided, speaker 16 collectively refers to the first and second speakers.

[0043] Microphone 17 is a device that converts sound into electrical signals. Processing device 11 includes an AD converter. Processing device 11 converts the analog audio signal output from microphone 17 into digital sound data via the AD converter and uses the sound data for processing. Alternatively, an AD converter may be provided after microphone 17. In this case, the audio signal is converted into audio data via the AD converter. The audio data is provided to processing device 11. When a first user uses mobile phone device 100A to talk to a second user, the first user's voice is input into microphone 17.

[0044] The opening / closing detection device 18 is a device that detects the display state of the display device 14. Specifically, the opening / closing detection device 18 includes a sensor that detects the angle formed by the display surfaces 41S and 42S, that is, the hinge angle of the hinge 49, and outputs a detection signal having an amplitude corresponding to the hinge angle. When the hinge angle θ indicated by the detection signal is, for example, in the range of 360°<θ<270°, the opening / closing detection device 18 detects that the display state of the display device 14 is the first display state (closed state). When the hinge angle θ indicated by the detection signal is, for example, in the range of 270°<θ<90°, the opening / closing detection device 18 detects that the display state of the display device 14 is the second display state (open state). The opening / closing detection device 18 outputs detection information 18a indicating the detection result to the processing device 11.

[0045] The processing device 11 reads the control program PR stored in the storage device 12 and executes the read control program PR to realize various functions. Figure 4 is a block diagram illustrating the functions of the processing device 11.

[0046] The processing device 11 functions as a communication unit 110A, an image generation unit 120A, a detection unit 130 , and a display control unit 140 by executing the control program PR.

[0047] Communication unit 110A uses communication device 13, speaker 16, and microphone 17 to conduct a call between a first user and a second user of mobile phone device 100A. Call modes include normal call and hands-free call. Normal call is a mode in which the first user holds mobile phone device 100A close to their face while making a call. Hands-free call is a mode in which the first user holds mobile phone device 100A away from their face while making a call. When the call mode is hands-free call, communication unit 110A increases the volume of the sound output from speaker 16 compared to when the call mode is normal call. Specifically, communication unit 110A controls the amplitude of the audio signal supplied to speaker 16 according to the call mode.

[0048] In addition, the communication unit 110A outputs identification information ID for identifying another telephone device used by the second user. The details of the identification information ID will be described later.

[0049] Image generation unit 120A generates a first image D1 and a second image D2. When a first user is talking to a second user, first image D1 indicates first information including the phone number of the other phone device. When image generation unit 120A generates first image D1, image generation unit 120A obtains identification information ID from communication unit 110A for identifying the other phone device. The identification information ID may be, for example, the phone number of the other phone device. The identification information ID may be, for example, the name of the second user. Alternatively, the identification information ID may include at least one of the phone number of the other phone device and the name of the second user. In this embodiment, the identification information ID includes the phone number of the other phone device and the name of the second user. Communication unit 110A identifies the name of the second user by referring to table TBL based on the phone number of the other phone device and generates an identification information ID including the phone number and the identified name of the second user.

[0050] Figure 5 is a plan view illustrating an example of a first image D1 displayed on the display surface 41S of the display device 14. Figure 5 In the first image D1 illustrated in FIG, an image of text indicating the second user is arranged in area A11, an image of text indicating the telephone number "03-5533-1001" is arranged in area A21, and an icon indicating that a call is in progress is arranged in area A31. The first information in this example is that the second user is "ABC Pizza," the telephone number of the other telephone device is "03-5533-1001," and the call is in progress.

[0051] The second image D2 indicates second information related to the second user, including information other than the first information. Image generation unit 120A generates second image D2 based on the identification information ID. Image generation unit 120A specifies the second user's address based on, for example, their phone number or name. For example, image generation unit 120A uses a web browser to search for an address based on their phone number or name to specify the second user's address. Alternatively, image generation unit 120A may use a map application to generate an image of a map containing the specified address, and use this map image as second image D2. In this case, second image D2 may be a map with the location indicating the second user's address at the center. By centering the map in this way, the first user can be informed of the situation surrounding the second user's address. Alternatively, image generation unit 120A may use a web browser to search for an address based on their phone number or name to specify a service provided by the second user, generate an image related to the specified service, and set this image as second image D2.

[0052] Figure 6 41S and 42S of the display device 14. Figure 6 In the second image D2 illustrated in the figure, an image of a map including the second user's address is arranged in area B11, an image of a street view showing the second user's address is arranged in area B21, and an image related to the second user's services is arranged in area B31. The second information in this example is the map including the second user's address, the street view of the second user's address, and the content of the services provided by the second user. Simply by talking on the phone with the second user, the first user can learn about the map including the address of "ABC Pizza," the second user's restaurant, and the menu of "ABC Pizza."

[0053] Figure 4 The detection unit 130 shown in the diagram detects a switching operation performed by the first user to switch the display state of the display device 14 from the first display state to the second display state. Specifically, the detection unit 130 detects that the display state of the display device 14 switches from the first display state to the second display state based on the detection information 18a.

[0054] When the display state of the display device 14 indicated by the detection information 18a is the first display state, the display control unit 140 causes the display device 14 to display the first image D1. In this example, when the display state of the display device 14 is the first display state, the display control unit 140 displays the first image D1 on the display surface 41S of the display device 14. For example, the display control unit 140 displays the first image D1 on the display surface 41S of the display device 14. Figure 5 The first image D1 is shown in the diagram.

[0055] Furthermore, when the detection unit 130 detects the switching operation, the display control unit 140 changes the display state of the display device 14 to the second display state and displays the second image D2 on the display device 14. For example, the display control unit 140 displays the second image D2 on the display surfaces 41S and 42S of the display device 14. Figure 6 The second image D2 is shown in the diagram.

[0056] When the first user switches the display state of the display device 14 from the first display state to the second display state, the first user rotates along the direction of arrow Q. Figure 1A In this change of the display state, it is preferable that the second image D2 is immediately displayed on the display device 14 when the display state of the display device 14 changes to the second display state. If the second image D2 can be prepared while the display state of the display device 14 is in the first display state, the second image D2 can be displayed on the display device 14 from the start of the second display state.

[0057] Therefore, when a call between the first user and the second user begins while the display state of display device 14 is in the first display state, image generation unit 120A generates second image D2. Specifically, when communication is established between mobile phone device 100A and another phone device, communication unit 110A outputs identification information ID to image generation unit 120A. Image generation unit 120A generates a second image ID based on the identification information ID, starting from the timing of receiving the identification information ID from communication unit 110A.

[0058] When the display device 14 is in the first display state, mobile phone 100A is smaller than when the display device 14 is in the second display state. Therefore, the first user typically communicates with the second user in a normal conversation. When making a call in an ordinary location, the first user holds mobile phone 100A in one hand, holds speaker 16 to their ear, and holds microphone 17 close to their mouth. When a call is received or a call is received, the first user identifies the other user's phone number by viewing first image D1. After confirming the other user's phone number, the first user holds mobile phone 100A close to their face to continue the call.

[0059] On the other hand, when the display state of the display device 14 changes to the second display state, detailed information about the second user is displayed on the display device 14. Therefore, the first user usually talks to the second user while viewing the second image D2 displayed on the display device 14. Therefore, when the display state of the display device 14 switches from the first display state to the second display state during a call, it is preferable to switch to a hands-free call even if the first user does not operate the operating device 15.

[0060] Therefore, when the display state of display device 14 is the second display state at the time when detection unit 130 detects the switching operation, communication unit 110A of this embodiment causes the second user's voice to be output from speaker 16 louder than when the display state of display device 14 is the first display state. Specifically, communication unit 110A causes the amplitude of the audio signal output to speaker 16 in the second display state to be greater than the amplitude of the audio signal output to speaker 16 in the first display state. Note that if speaker 16 includes multiple speakers, the speaker that outputs the second user's voice in the first display state may be different from the speaker that outputs the second user's voice in the second display state. For example, the speaker that outputs the second user's voice in the first display state may be the first speaker, while the speaker that outputs the second user's voice in the second display state may be the second speaker. When the speaker that outputs the second user's voice is changed according to the display state, it is preferable that the second user's voice be louder in the second display state than in the first display state. By using different speakers, it is possible to selectively use a speaker for low volume and a speaker for high volume.

[0061] Image generation unit 120A can notify communication unit 110A of the completion of generation of second image D2. Upon receiving the notification, communication unit 110A can cause speaker 16 to output a predetermined sound that prompts the display state of display device 14 to change from the first display state to the second display state. By outputting the predetermined sound from speaker 16, the first user can be informed that the second image D2 is ready for display. Note that upon completion of generation of second image D2, image generation unit 120A can generate an image that prompts the change in display state to notify the first user of the completion, and output the generated image to display control unit 140. Display control unit 140 causes display device 14 to display the image. Alternatively, a vibrator can be provided in 100A, and the completion of generation of second image D2 can be notified to the first user by activating the vibrator. If notification is provided through vibration, upon completion of generation of second image D2, image generation unit 120A can output a control signal to the vibrator for a predetermined time.

[0062] Next, the operation of the mobile phone device 100A according to the first embodiment will be described. Figure 7 1 is a flowchart illustrating the operation of the mobile phone device 100A. The processing device 11 determines whether the display state of the display device 14 is the first display state based on the detection information 18a (step S1). When the determination result of step S1 is negative, the processing device 11 repeats step S1 until the determination result of step S1 is positive. When the determination result of step S1 is positive, the processing device 11 determines whether the call between the first user and the second user has started (step S2). The start of a call means that communication has been established between the mobile phone device 100A and another telephone device used by the second user. Specifically, the processing device 11 determines that the call has started based on the communication information output from the communication device 13.

[0063] If the determination result of step S2 is negative, the processing device 11 returns the process to step S1. On the other hand, if the determination result of step S2 is positive, the processing device 11 generates a first image D1 based on the identification information ID (step S3).

[0064] Next, the processing device 11 causes the display device 14 to display the first image D1 (step S4). Since the display state of the display device 14 is the first display state, the first image D1 is displayed on the display surface 41S. Since the first image D1 indicates the first information including the telephone number of the other telephone device, the first user can confirm the telephone number of the other telephone device in the state where the mobile phone device 100A is closed. Since the identification information ID in this example includes the name of the second user, Figure 5 As shown in the diagram, the first image D1 includes an image "ABC Pizza" of the second user's name located in the area A11 in addition to the image "03-5533-1001" of the telephone number located in the area A21.

[0065] Next, the processing device 11 generates a second image D2 based on the identification information ID (step S5). The second image D2 indicates second information including information other than the first information. For example, Figure 6 As shown in the diagram, in the second image D2, as information other than the telephone number "03-5533-1001" and the name of the second user "ABC Pizza", a map containing the address of the second user is arranged in the area B11, and an image indicating the content of the service provided by the second user is arranged in the area B31.

[0066] Next, the processing device 11 determines whether a switching operation of the display device 14 from the first display state to the second display state by the first user is detected (step S6). Specifically, the processing device 11 determines whether a switching operation is detected based on the detection information 18a.

[0067] If the determination result of step S6 is negative, processing device 11 determines whether the call has ended based on the communication information (step S10). If the determination result of step S10 is positive, processing device 11 ends the process. On the other hand, if the determination result of step S10 is negative, processing device 11 returns the process to step S6.

[0068] When the determination result of step S6 is positive, processing device 11 changes the display state of display device 14 from the first display state to the second display state (step S7). Specifically, processing device 11 changes the display using only display surface 41S to the display using display surfaces 41S and 42S.

[0069] Next, processing device 11 changes the call mode from normal to hands-free (step S9). Specifically, processing device 11 increases the amplitude of the audio signal output to speaker 16 compared to a normal call. By switching to hands-free, the first user can talk to the second user while viewing the second image D2 displayed on display surfaces 41S and 42S. Thus, since the first user can interact with the second user while referring to the information about the second user displayed on large-screen display device 14, they can communicate effectively with the second user.

[0070] The processing device 11 functions as the image generation unit 120A in steps S1, S2, S3, and S5. The processing device 11 functions as the display control unit 140 in steps S4, S7, and S8. The processing device 11 functions as the communication unit 110A in steps S9 and S10. The processing device 11 functions as the detection unit 130 in step S6.

[0071] As described above, the mobile phone device 100A according to the first embodiment includes: the display device 14 capable of switching the display state between a first display state and a second display state in which the display area is larger than the display area in the first display state; the communication unit 110A that performs a call between a first user of the mobile phone device 100A and a second user who is talking using another telephone device; the image generation unit 120A that generates a first image D1 indicating first information including a telephone number of another telephone device based on identification information ID for identifying the other telephone device, and Based on the identification information ID, a second image D2 indicating second information including information other than the first information and related to the second user is generated; a detection unit 130, the detection unit 130 detects a switching operation performed by the first user to switch the display state of the display device 14 from the first display state to the second display state; and a display control unit 140, the display control unit 140 causes the display device 14 to display the first image D1 when the display state of the display device 14 is the first display state, and changes the display state of the display device 14 to the second display state and causes the display device 14 to display the second image D2 when the detection unit 130 detects the switching operation.

[0072] According to mobile phone device 100A, since the second image D2 related to the second user is displayed on display device 14 in the second display state of the large screen, the first user can obtain information related to the second user during the call. In this case, the first user does not need to perform any input operation on mobile phone device 100A in order to display the second image D2 on display device 14. As a result, the operability and convenience of mobile phone device 100A are improved.

[0073] The mobile phone device 100A includes a speaker 16 that outputs the second user's voice and a communication unit 110A. When the detection unit 130 detects the switching operation, the communication unit 110A makes the second user's voice output from the speaker 16 louder than the second user's voice output from the speaker 16 when the display state of the display device 14 is the first display state.

[0074] When the display state of the display device 14 is switched from the first display state to the second display state during a call in normal call mode, it is necessary to change the call mode to a hands-free call. According to the mobile phone device 100A, when the detection unit 130 detects the switching operation, the communication is changed to a hands-free call, so that the first user does not need to perform any input operation on the mobile phone device 100A. Thus, the operability and convenience of the mobile phone device 100A are improved. In addition, when the display state of the display device 14 is switched from the first display state to the second display state during a call and then switched back to the first display state, the communication unit 110A can change the call from a hands-free call to a normal call. This is because when the first user switches back to the first display state, it is assumed that the first user intends to make a normal call through a one-handed operation.

[0075] <Second embodiment>

[0076] Mobile phone device 100A according to the first embodiment described above generates a second image D2 based on identification information ID. Mobile phone device 100B according to the second embodiment is similar in configuration to mobile phone device 100A according to the first embodiment, except that second image D2 is generated based on identification information ID and call information X indicating the content of a call. The differences between mobile phone device 100B according to the second embodiment and mobile phone device 100A according to the first embodiment will be described below.

[0077] Figure 8 The block diagram illustrates the functions realized by the processing device 11 of the mobile phone device 100B executing the control program PR. By executing the control program PR stored in the storage device 12, the processing device 11 of the mobile phone device 100B functions as the communication unit 110B instead of the communication unit 110B. Figure 4 The communication unit 110A shown in the diagram in FIG, and functions as the image generation unit 120B instead of Figure 4 The role of the image generation unit 120A shown in the figure.

[0078] The communication unit 110B is different from the communication unit 110A that does not output the call information X to the image generation unit 120A in that the identification information ID and the call information X are output to the image generation unit 120B.

[0079] Image generation unit 120B generates second image D2 based on identification information ID and call information X output from communication unit 110B. Call information X indicates the content of the call when display device 14 is in the first display state. Specifically, image generation unit 120B specifies keywords included in the call based on call information X and generates second image D2 based on the specified keywords and identification information ID. Keyword identification can be, for example, one or more words included in the first user's speech and in the second user's speech. Alternatively, the most frequently used word among the multiple words included in the first user's speech and the second user's speech is the keyword.

[0080] For example, suppose that the first user speaks to the doctor who is the second user via an emergency call.Alternatively, suppose that the first user needs to attempt to resuscitate her husband using an AED. Figure 9 is a plan view illustrating an example of a first image D1 displayed on the display surface 41S of the display device 14. Figure 9 In the first image D1 illustrated in FIG, an image of text indicating an emergency call is arranged in area A12, an image of text indicating the telephone number "119" is arranged in area A22, and an icon indicating that a call is in progress is arranged in area A32. The first information in this example is that the call is an emergency call, the telephone number of the other telephone device is "119", and the call is in progress.

[0081] Furthermore, it is assumed that the following call is made when the display state of the display device 14 is the first display state.

[0082] User 1: "My husband collapsed and he's not breathing."

[0083] Second user: "Is there an AED nearby?"

[0084] First user: “I have an AED, but I don’t know how to use it.”

[0085] Second user: "The use of an AED is very simple. Let me explain."

[0086] In this call, the words included in the first user's speech and in the second user's speech are "AED" and "usage." Therefore, the image generation unit 120B specifies "AED" and "usage" as keywords. Furthermore, the image generation unit 120B specifies that the second user is compatible with the video call based on the telephone number "119" indicated by the identification information ID. Furthermore, the image generation unit 120B searches based on "AED" and "usage" using, for example, a web browser, and generates an image related to the usage of the AED as part of the second image D2. Furthermore, the image generation unit 120B generates an image of the doctor who is the second user as part of the second image D2. The image generation unit 120B generates an image related to the resuscitation method using the AED as part of the second image D2.

[0087] Figure 10 41S and 42S of the display device 14. Figure 10 In the second image D2 shown in the diagram, an image about how to use an AED is placed in area B12, an image of the doctor serving as the second user is placed in area B22, and an image about the resuscitation method using the AED is placed in area B32. The second information in this example includes how to use the AED, the appearance of the second user, and the resuscitation method using the AED.

[0088] Next, the operation of the mobile phone device 100B according to the second embodiment will be explained. Figure 11 is a flowchart illustrating the operation of the mobile phone device 100B according to the second embodiment. Figure 7 The operation of the mobile phone device 100A according to the second embodiment is similar to that of the mobile phone device 100A according to the first embodiment, except that step S5a is adopted in step S5 illustrated in FIG.

[0089] In step S5a, the processing device 11 generates the second image D2 based on the identification information ID and the call information X when the display state of the display device 14 is the first display state. In step S5a, the processing device 11 functions as the image generation unit 120B.

[0090] As described above, mobile phone device 100B according to the second embodiment generates a second image D2 to be displayed on display device 14 based on identification information ID and call information X when the display state of display device 14 is the second display state. Thus, compared to a case where second image D2 is generated based on identification information ID without considering call information X, useful information is provided to the first user. As a result, the convenience of mobile phone device 100B is improved.

[0091] Note that the information displayed in areas B12 and B32 can be transmitted from mobile phone device 100 to the terminal device of the second user. For example, if the second user is a doctor, the information is displayed on the terminal device, allowing the doctor to confirm the information displayed on mobile phone device 100 of the first user. The doctor can then more easily explain the response method, etc. to the first user through a phone call while grasping the information obtained.

[0092] <Third embodiment>

[0093] Figure 12A and Figure 12B This is a perspective view illustrating the appearance of a mobile phone device 100C according to a third embodiment of the present disclosure. Mobile phone device 100C according to this embodiment differs from mobile phone device 100A according to the first embodiment in the detailed configuration of display device 14. Furthermore, mobile phone device 100C differs from mobile phone device 100A in that communication unit 110C is used instead of communication unit 110A.

[0094] As in the first embodiment, mobile phone device 100C includes housings 41 and 42 and hinge 49. In the first embodiment, mobile phone device 100A has two display surfaces 41S and 42S. On the other hand, mobile phone device 100C according to this embodiment has three rectangular display surfaces 43S, 44S, and 45S. Specifically, housing 41 has display surfaces 45S and 44S on its front and rear surfaces, respectively, and housing 42 has display surface 43S on one of its front and rear surfaces. Hinge 49 connects the long side of the rectangular end surface 41E of housing 41 facing display surface 43S and the long side of the rectangular end surface 42E of housing 42 facing display surface 44S.

[0095] In this embodiment, the hinge angle formed by the display surfaces 43S and 44S changes as the hinge 49 rotates. In this embodiment, by setting the hinge angle to 0°, the user can set the display state of the display device 14 of the mobile phone device 100C to the first display state. In the first display state, as shown in FIG. Figure 12A As shown in the diagram, the display surfaces 43S and 44S are opposite to each other, and display is performed only on the display surface 45S facing outward. In this embodiment, by setting the hinge angle to 180°, the first user can set the display state of the display device 14 of the mobile phone device 100C to the second display state. In the second display state, as shown in FIG. Figure 12BAs shown in the diagram, display surfaces 43S and 44S face outward, and display is performed on both display surfaces 43S and 44S. Here, the total display area of ​​display surfaces 43S and 44S is larger than the display area of ​​display surface 45S. Thus, the second display state is a display state in which the display area is larger than that of the first display state.

[0096] The first speaker 16a and the first microphone 17a used when the display state of the display device 14 is the first display state are arranged on the surface where the display surface 45S of the housing 41 is located. The second speaker 16b and the second microphone 17b used when the display state of the display device 14 is the second display state are arranged on the surface where the display surface 43S of the housing 41 is located.

[0097] Figure 13 The block diagram illustrates the functions realized by the processing device 11 of the mobile phone device 100C executing the control program PR. By executing the control program PR stored in the storage device 12, the processing device 11 of the mobile phone device 100C functions as the communication unit 110C instead of the communication unit 110C. Figure 4 The role of the communication unit 110A shown in the figure.

[0098] When the display state of the display device 14 changes to the first display state, the communication unit 110C converts the voice of the first user into an electric signal using the first microphone 17 a and outputs the voice of the second user from the first speaker 16 a .

[0099] When the display state of the display device 14 changes to the second display state, the communication unit 110C converts the voice of the first user into an electric signal using the second microphone 17 b and outputs the voice of the second user from the second speaker 16 b .

[0100] Therefore, when the display state of the display device 14 is in the second display state at the timing when the detection unit 130 detects the switching operation, the communication unit 110C makes the second user's voice output from the second speaker 16b louder than the second user's voice output from the first speaker 16a when the display state of the display device 14 is in the first display state. As a result, even if the first user does not operate the operating device 15, the normal call is switched to the hands-free call.

[0101] Mobile phone device 100C according to the third embodiment has the same effects as mobile phone device 100A according to the first embodiment. In the third embodiment, display surfaces 43S and 44S face each other in the first display state. Therefore, since the first user's finger or the like does not touch display surfaces 43S and 44S, there is an advantage that, for example, in the first display state, processing such as disabling operation of the touch panel provided on display surfaces 43S and 44S is not required.

[0102] <Fourth embodiment>

[0103] The appearance of the mobile phone device 100D according to the fourth embodiment of the present disclosure is similar to that of the reference Figure 12A and Figure 12B The functions of the mobile phone device 100D are the same as those of the mobile phone device 100C except that the communication unit 110D is used instead of the communication unit 110C and the image generation unit 120B is used instead of the image generation unit 120A.

[0104] Figure 14 The block diagram illustrates the functions realized by the processing device 11 executing the control program PR. By executing the control program PR stored in the storage device 12, the processing device 11 of the third embodiment functions as the communication unit 110C instead of Figure 4 The role of the communication unit 110A shown in the figure.

[0105] The mobile phone device 100D includes the image generation unit 120B described in the second embodiment. Then, the mobile phone device 100D generates the second image D2 based on the identification information ID and the call information X. Since this point is the same as the second embodiment, the mobile phone device 100D has the same effect as the mobile phone device 100B according to the second embodiment. In the fourth embodiment, the display surfaces 43S and 44S are opposite to each other in the first display state. Therefore, since the first user's finger or the like does not touch the display surfaces 43S and 44S, there is an advantage that, for example, in the first display state, there is no need for processing such as disabling the operation of the touch panel provided on the display surfaces 43S and 44S.
