Description

  The present invention relates to a portable information terminal device.

  Mobile information terminal devices such as mobile phones can send and receive electronic mail (hereinafter referred to as “mail”) to and from other users.

  When the mail is received, the portable information terminal device notifies the user that the mail has been received by some alert. For example, notification is made by voice assigned to mail reception, pictograms (visual symbols) displayed at the corners of the screen, vibrations, and the like.

  By the way, the work of confirming the received mail during the creation of the mail is necessary to prevent passing with the mail transmission / reception partner. For example, it is assumed that user A and user B have a meeting at 9:00. User A, who is likely to arrive at 9:30 am, is creating an email to User B that says “Today's meeting will be late”. Suppose you receive an email saying "I will change." In this case, if the user A transmits the mail from the user B without confirming it, the user B may receive the message “I will be late” for the conference “changed from 10:00”.

  In order to prevent such a passing, it is necessary to make a habit of sending mail after confirming the contents of the received mail. Alternatively, the contents of the received mail may be frequently confirmed even while the mail is being created. However, in order to confirm the received mail text during mail creation, the mail creation mode must be terminated once, the received mail confirmation mode must be transitioned, and after reading, the mail creation mode must be entered again. For this reason, it is complicated for the user.

  Patent Document 1 discloses a technique for reading a received mail. According to this technique, even when a mail is being created, by pressing the reading start button, the text of the received mail is synthesized and output. Therefore, the user can confirm the received mail while creating the mail.

  According to the technique disclosed in Patent Document 1, the user can check the contents of the received mail even while the mail is being created. However, since voice is used as an output means, the user has to consider such as using an earphone in a public place or the like. Further, Patent Document 1 does not mention a method of reading a received mail during mail creation, confirming the content of the received mail, and transmitting the created mail.

  Patent Document 2 discloses a technique for displaying the contents of an incoming mail as a banner in a part of the display, for example, the mail display area at the bottom of the screen.

  According to this technique, even when a mail is being created, it is possible to scroll and confirm the contents of the received mail using a fixed partial area of the display screen 41. However, since the received mail is scrolled and displayed in a fixed and limited area, it is difficult and complicated to confirm the long mail.

  Patent Document 3 proposes a technique for displaying a received mail in a telop according to a set condition.

  According to the technique disclosed in Patent Document 3, conditions for performing telop display must be set in advance, which is complicated. Furthermore, there is no disclosure of a dynamic condition setting method, such as designating “reception of new mail from a mail transmission destination being created” as a trigger for displaying a telop.

The problem that a difference in information transmission / reception timing occurs is not limited to the transmission / reception of mail, but also occurs when related information is received while inputting arbitrary information.

  As described above, according to the present invention, it is possible to display received information in an appropriate form according to the display state.

FIG. 1 is a functional configuration diagram of a mobile phone 100 according to an embodiment of the present invention.
As shown in the figure, the mobile phone 100 includes a control unit 1, a storage unit 2, a transmission / reception unit 3, a display unit 4, an operation unit 5, and an audio processing unit 6. These are connected to each other by a system bus 7.

  The control unit 1 includes a CPU (Central Processing Unit, not shown), and in accordance with an operation program (not shown) stored in the storage unit 2, the storage unit 2, the transmission / reception unit 3 via the system bus 7. Then, data is exchanged with the display unit 4, the operation unit 5, and the voice processing unit 6, and the cellular phone 100 is caused to function as the cellular phone according to the present embodiment. At that time, the control unit 1 reads data from the above-described functional blocks such as the storage unit 2 into a register (not shown) built in the control unit 1 as necessary, and performs an operation on the data. After that, the data generated by the calculation is sent to each functional block.

  The storage unit 2 is physically, for example, a ROM (Read Only Memory), a RAM (Random Access Memory), a hard disk, etc., and includes the above-described operation program, a mail 21 being created, an address book 23, a received mail 25, And other necessary information is stored.

  Here, the mail 21 being created is an electronic mail (hereinafter simply referred to as “mail”) being created by the user of the mobile phone 100.

  Further, the address book 23 is a table in which information such as the e-mail address of the main partner with whom the user of the mobile phone 100 communicates by mail is posted. The address book 23 is mainly created by the user's own intention, but may be additionally written based on information automatically acquired from mail received on the mobile phone 100.

  The received mail 25 is mail that arrives at the mobile phone 100 from another mail transmitting / receiving terminal.

  The transmission / reception unit 3 converts voice data, transmission mail data, and the like delivered from each functional block via the system bus 7 into a radio signal, and receives a receiver or a predetermined radio wave relay of a destination mail transmission / reception terminal. Then, wireless transmission from the antenna 31 is performed. The transmission / reception unit 3 also converts voice data, received mail data, and the like wirelessly transmitted to the mobile phone 100 from another mail transmission / reception terminal into an aspect that each functional block can interpret after being captured by the antenna 31, The data is delivered to each functional block via the system bus 7.

  The transmission / reception unit 3 supports one-way communication such as mobile TV simple broadcasting such as one-segment broadcasting, digital radio, etc., in addition to bidirectional communication such as cellular phone voice data and mail data. It corresponds also to. For example, a radio signal of a one-segment television broadcast captured by the transmission / reception unit 3 with the antenna 31 can be displayed on the display unit 4 as a viewable television image through a predetermined conversion process.

  The display unit 4 is a liquid crystal display, for example, and incorporates a driver (not shown) for driving the display unit 4 according to an instruction from the control unit 1. In the mobile phone 100, the creating mail 21 and the received mail 25 are displayed on the display unit 4. This point will be described in detail later.

  The operation unit 5 is, for example, a keyboard provided with a numeric keypad that is convenient for the user to input a telephone number. The operation unit 5 identifies the key pressed by the user, converts it to a key code corresponding to the key, and transmits the key code to the control unit 1. An operation content specifying unit (not shown) is included. In the present embodiment, since the mail transmission / reception function is important, the keyboard described above may be a simple QWERTY keyboard used in a so-called smartphone so that mail can be easily created.

  The voice processing unit 6 performs voice input, encoding, and decoding of voice data wirelessly received by the transmission / reception unit 3 during a call. The voice processing unit 6 includes a microphone 63 for inputting a user's voice and a speaker 61 for reproducing a voice of a speaker of another mobile phone that has arrived at the mobile phone 100.

  2A and 2B show an example of a display screen 41 which is a user interface of the display unit 4 in FIG. It is assumed that the display screen 41 has a width of 240 pixels and a height of 480 pixels.

  The portions corresponding to the first to 40th pixels counted from the upper end of the display screen 41 are used as a radio wave reception state display area 411, a pictogram area 412, and a current time display area 413 in order from the left. The pictogram area 412 is an area for notifying the reception of mail. This will be described in detail later.

  A portion 414 having a width of 240 pixels and a height of 400 pixels, which corresponds to the 41st to 440th pixels counted from the upper end of the display screen 41, is used for multiple purposes. Therefore, this portion will be referred to as a multipurpose display area 414 below.

  The portion corresponding to the 441st to 480th pixels counted from the upper end of the display screen 41, that is, the portion 415 corresponding to the 1st to 40th pixels counted from the lower portion of the display screen 41 is the multi-purpose display area 414. It is used to indicate that a specific function is assigned to some keys of the keyboard of the operation unit 5 depending on the state. FIG. 2A and FIG. 2B show, as an example, a state in which “return”, “display”, and “menu” functions are assigned to specific keys of the operation unit 5 in order from the left. Yes.

  The multipurpose display area 414 is used as, for example, a mail creation screen 416 for creating a mail to be transmitted. If the mail creation screen 416 is narrow, it is inconvenient to edit the mail text.

  Therefore, the area that must be secured as a minimum for the mail creation screen 416 is predetermined in pixel units, for example, as “minimum required size of mail display during creation” as shown in FIG. Stored. In the case of the example shown in FIG. 2C, the minimum required size for mail display during creation is determined to be 240 pixels wide and 200 pixels high. Therefore, when creating a mail, a mail creation screen 416 having a width of at least 240 pixels and a height of 200 pixels appears in the multipurpose display area 414. FIG. 2A shows a state where such a minimum area mail creation screen 416 is displayed.

  The user can enlarge the mail creation screen 416 to an arbitrary size not exceeding the size of the multipurpose display area 414 by operating the operation unit 5. Alternatively, in principle, the mail creation screen 416 occupies the entire multi-purpose display area 414. When a specific situation occurs, the mail creation screen 416 is reduced while satisfying the minimum required size of the mail display during creation. May be. This is because it is more convenient for the user to create an email in a state where the entire text can be read as much as possible without scrolling or the like.

  On the other hand, the multipurpose display area 414 is also used as a display screen (received mail display screen) 417 for mail received from another terminal. Simple display of information related to incoming mail is performed in the pictogram area 412. Therefore, when the control unit 1 determines that the information related to the received mail is to be displayed even if part of the multipurpose display area 414 is broken, the area of the information related to the received mail is larger than the pictogram area 412. It is reasonable to apply the indication. On the other hand, since the information related to the received mail is necessary only for the user to read, the minimum required size of the mail display during creation shown in FIG. Smaller is acceptable. From the viewpoint of effectively using the multi-purpose display area 414 having a limited area, it is also desirable to do so.

  Therefore, in order to display the information related to the received mail, the minimum area that must be secured in the multipurpose display area 414 is, for example, “minimum required size of received mail display” as shown in FIG. It is determined in advance and stored in the storage unit 2. In the case of the example shown in FIG. 2D, the minimum required size of the received mail display is defined as a width of 240 pixels and a height of 80 pixels. This size satisfies the above-mentioned condition that it is larger than the pictogram area 412 and smaller than the minimum required mail display size during creation.

  Therefore, when the mobile phone 100 receives a mail and the control unit 1 determines that information related to the received mail is displayed in the multipurpose display area 414, the multipurpose display area 414 has at least A received mail display screen having a width of 240 pixels and a height of 80 pixels appears. FIG. 2B shows a state where the received mail display screen 417 having such a minimum area is displayed.

  As will be described in detail later, how the information related to the mail is displayed is determined by the control unit 1 that acquires the information on how the multipurpose display area 414 is used from the display unit 4. And not a user. This is because the user is not forced to set various conditions. However, since how much effort is felt as a burden depends on the skill level of the user, the display mode of the information related to the mail is changed for the user who is familiar with the customization of the communication device. It is good also as a specification made to do. However, in the following description, it is assumed that there is no such change by the user.

  FIG. 3 shows a specific example of the mail creation screen 416. FIG. 3A is an example of a screen when creating a mail with the minimum required size for the mail being created, and corresponds to FIG. FIG. 3B shows an example of a screen when the multi-purpose display area 414 is created using the entire 414. The size of the mail creation screen 416 is the width of 240 pixels which is the size of the multi-purpose display area 414. Equal to 400 pixels.

  The contents of the mail are the same in FIG. 3A and FIG. In either case, “Taro Yamada” is shown as the mail address, “Re: Today's drink ...” as the mail subject, and “Slightly late” as the text. After the text, a cursor is displayed, as indicated by a thick vertical bar, prompting you to write the rest of the text.

  FIG. 4 shows an example in which a specific example of the mail creation screen 416 shown in FIG. 3 is applied to the display screen 41 shown in FIG. FIG. 4A and FIG. 4B both show that the radio wave reception state of the mobile phone 100 is good and the current time is 18:46.

  However, in the case of FIG. 4B, the multi-purpose display area 414 is used to the maximum and the mail creation screen 416 is displayed. This is convenient if the user wants to concentrate on composing mail. On the other hand, in the case of FIG. 4A, the upper half of the multi-purpose display area 414 having a width of 240 pixels and a height of 200 pixels is used for displaying a television screen by so-called one-segment broadcasting. . The remaining lower half of the multipurpose display area 414 has the minimum required size of the mail display during creation shown in FIG. 2C, and a mail creation screen 416 is displayed here. This is convenient when the user of the mobile phone 100 wants to create a mail while enjoying television broadcasting.

  FIG. 5 shows an example of the address book 23 stored in the storage unit 2 of FIG. As shown in the drawing, names such as “Taro Yamada” and “Jiro Kawano” and their mail addresses are associated with each other. Multiple addresses may correspond to one name as in the case of “Taro Yamada”, or only one address corresponds to one name as in the case of “Jiro Kawano”. You may do it.

  6A to 6C show examples of the received mail 25 stored in the storage unit 2 of FIG. These received mails 25 have the same date, sender, and subject. The main points of the text are the same in that the start time of “Today's Drinking Party” is changed to 19:30, but the lengths of the main texts are different from each other.

  In the following, it is assumed that the user of the mobile phone 100 starts creating an email addressed to “Taro Yamada” at 18:44. Then, as shown in FIG. 6, it is assumed that a mail from “Taro Yamada” arrives at the mobile phone 100 at 18:45, one minute later. Then, as shown in FIG. 4, it is assumed that the mail addressed to “Taro Yamada” is still being created even at 18:46, one minute later.

  In the following, in order to facilitate understanding of the operation of the mobile phone 100 according to the present embodiment, the content shown in FIG. 6 is stored as the received mail 25 in the storage unit 2 of FIG. A description will be given of what changes occur on the screen 41.

  As shown in FIG. 4, the user of the mobile phone 100 tries to tell “Taro Yamada” that “being late” for “a drinking party” and creates a mail at least from 18:44 to 18:46. Yes. On the other hand, at 18:45 during the creation, “Taro Yamada” informs the user of the mobile phone 100 that “Drinking party” has been changed to “19:30” start. The user of the mobile phone 100 intends to simply tell “Taro Yamada” that “being late”. However, if the time for exchanging mails is complicated, the user of the mobile phone 100 There may be confusion with “Taro Yamada”. For example, there is a possibility that “Yamada Taro” may be misunderstood when the user of the mobile phone 100 says “delayed” based on the reference. That is, it is unclear whether the user of the mobile phone 100 is “delayed” with respect to the originally promised time or “delayed” with respect to the newly set time of “19:30”. It is possible to become.

  The mobile phone 100 can prevent such a passing or passing by the following operation.

  The control unit 1 in FIG. 1 constantly monitors the received mail 25 in the storage unit 2. When a new received mail 25 is stored in the storage unit 2, the control unit 1 starts a received mail display policy determination operation.

  In this operation, the control unit 1 first attempts to specify the name of the sender.

  Hereinafter, the name of the sender of the new received mail 25 will be referred to as the sender.

  For example, in the case of FIG. 6, the control unit 1 refers to the address book 23 shown in FIG. 5 from the sender's mail address “yamada@yyy.co.jp” and the sender is “Taro Yamada”. Determine that there is.

  Subsequently, the control unit 1 instructs the display unit 4 in FIG. 1 to inform the user how to use the display screen 41 at the present time, and based on the data received from the display unit 4, the control unit 1 displays the multipurpose display area 414. To determine whether an email is being created.

  If a mail has not been created, the control unit 1 causes the display screen 41 to display information related to the received mail by any known method. When it is determined that the mail is being created, the control unit 1 determines whether the destination of the mail being created is “Taro Yamada”, who is the sender of the newly received mail. Is determined. Since the data received from the display unit 4 by the control unit 1 earlier includes information for identifying the destination of the mail being created, this determination is possible.

  In the following, the mail address being created by the user of the mobile phone 100 will be referred to as a scheduled addressee. The term “scheduled” is used here because the user has not yet sent an email and sent an email that was being created or completed due to the following information regarding the received email or due to other circumstances. This is because there are various cases such as no transmission or transmission to another destination.

  If the sender is different from “Taro Yamada” who is the scheduled recipient, for example “Jiro Kawano”, the control unit 1 instructs the display unit 4 to send an email from “Jiro Kawano” to the pictograph screen 412. Only the fact that it was received is displayed simply.

  If the sender's name cannot be specified, the fact that the mail has been received from someone is simply displayed.

  As described above, since the simplified display is performed if the scheduled addressee is different from the sender, it is possible to suitably check the mail received during mail creation.

  When the control unit 1 determines that the sender and the scheduled destination match, the control unit 1 acquires the mail display size being created from the display unit 4. The mail display size during creation is, for example, 240 pixels wide and 200 pixels high in the case of FIG. 4A, and 240 pixels wide and 400 pixels high in FIG. 4B.

  In the present embodiment, the display screen 41 is assumed to have a long vertical direction. Therefore, in the following, in order to facilitate understanding, the multi-purpose display area 414 is assumed to be subjected to various divisions only in the vertical direction, and the width of the portion displayed as a result of the various divisions is 240 pixels. And

  When the control unit 1 obtains the mail display size being created from the display unit 4, the multipurpose display area 414 has a portion that can be used to display information related to the received mail. Just consider what you have. If the information related to the received mail can be displayed without hindering the creation of the mail and without squeezing the area used independently of the mail, the user will not be interrupted to create the mail. This is because the TV screen being viewed is not obstructed, which is convenient for the user.

Therefore, assuming that there is a portion that can be used to display information related to received mail in the multipurpose display area 414, the control unit 1 obtains a margin size defined by the following equation.
Spare size = Mail display size during creation-Minimum required size of mail display during creation-Minimum required size of received mail display (Formula 1)
Here, the mail display size being created is acquired from the control unit 4, and the minimum required mail display size (FIG. 2C) and the received mail display minimum required size (FIG. 2D) are being stored in the storage unit. 2 is stored.

  When the margin size is smaller than 0, the control unit 1 determines to display the information in the pictogram area 412 in a simple manner without displaying the received mail display screen 417 in the multipurpose display area 414. Although this display mode is a simple display, it is possible to confirm the reception of the mail without blocking the mail creation screen 416 or the television screen.

  Specifically, when the display screen 41 is the one shown in FIG. 4A, 200 pixels of the multi-purpose display area 414 have already been used for displaying a TV screen unrelated to mail, and Since the minimum required size of 200 pixels is used as the mail creation screen 416, the margin size is 200−200−80 = −80 <0. Therefore, as shown in FIG. 8A, for example, an icon indicating an incoming mail and a sender are displayed in the pictogram area 412.

  On the other hand, when the display screen 41 is as shown in FIG. 4B, the margin size = 400−200−80 = 120 ≧ 0. That is, a part of the mail creation area 416 is cut away, and there is room for displaying a larger amount of information about the received mail than the display in the pictogram area 412 in the empty area.

  Thus, the received mail can be interrupted and displayed with high visibility according to the window size during which the mail function is displayed.

  In the following, taking the case where the display screen 41 is the one shown in FIG. 4B as an example, the multi-purpose display area 414 will be displayed when the received mail has the three types of lengths shown in FIGS. It will be described how such a mode is obtained.

  First, if the entire text of a new received mail 25 is displayed on the display screen 41, the control unit 1 determines how much size is required.

  For example, when the new received mail 25 is the one shown in FIGS. 6A and 7A, the received mail full text display size is 80, which is the received mail display stored in the storage unit 2. It is equal to the minimum required size (FIG. 2 (d)). Therefore, as shown in FIG. 8B, the control unit 1 cuts the e-mail creation area by 80 pixels from the state shown in FIG. 4B, and uses the free area shown in FIGS. 6 and 7A. Displays the full text of the email.

  On the other hand, the new received mail 25 is longer than that shown in FIGS. 6 (a) and 7 (a), FIG. 6 (b) and FIG. 7 (b), or FIG. 6 (c). If the size of the outgoing mail creation area 416 does not fall below the minimum required mail display size during creation, the information related to the new received mail 25 is displayed in the multi-purpose display area in as much detail as possible. It is convenient for the user to be displayed on 414.

Therefore, as shown in FIGS. 6B and 7B, or FIGS. 6C and 7C, the control unit 1 determines that the received mail full-text display size is the minimum required size of the received mail display. If it exceeds 80 pixels, the received mail displayable size is calculated by the following equation.
Received mail display size = Mail display size during creation-Mail display minimum required size during creation ... (Formula 2)

  The mail display size during creation is 400 pixels as shown in FIG. 4B, and the minimum required size of mail display during creation is 200 pixels as shown in FIG. 2C. Therefore, the received mail displayable size is 400−200 = 200 pixels. This received mail displayable size is the maximum value of the area that can be used to display received mail without disturbing the user's mail creation work.

Since (Equation 1), (Equation 2) is
Received mail display size = margin size + received mail display minimum required size (Equation 3)
Can also be expressed.

  The control unit 1 determines whether or not the entire new received mail 25 falls within the calculated received mail displayable size.

  For example, in the case of FIGS. 6B and 7B, the received mail full-text display size of 100 pixels is equal to or smaller than the 200 pixels that is the received mail displayable size obtained above. Therefore, it is possible to display the entire new received mail 25 in a batch while ensuring a sufficient mail creation area 416. Therefore, the multi-purpose display area 414 becomes as shown in FIG. That is, the original mail creation area in FIG. 4B is deleted by 100 pixels, the size of the mail creation area 416 is reduced to 300 pixels, and the empty 100-pixel area is replaced by the entire text of the new received mail 25. A received mail display screen 417 for displaying all at once is displayed.

  In this way, since the mail can be created while checking the received mail, it is convenient for the user of the mobile phone 100.

  However, in the case of FIG. 6 (c) and FIG. 7 (c), the received mail full text display size is as large as 300 pixels. Only 100 pixels remain. This would be less than the minimum required size of the mail display during creation shown in FIG. Therefore, in such a case, only the displayable range is displayed for the newly received mail 25 while leaving the mail creation area of the same size as the minimum required size of the mail display being created in the multipurpose display area 414. . Such a display mode is shown in FIG. From the simple calculation already described, it can be seen that the size of the information related to the new received mail 25 can be displayed is only 200 pixels. As shown in FIG. 7C, since a size of 300 pixels is originally required to display the entire new received mail 25 collectively, in the case of FIG. In the received mail displayed on the screen, information for 100 (= 300-200) pixels must be omitted.

  Therefore, as shown in the case of FIG. 9B, for example, a scroll bar is displayed on the right side of the area indicating the content of the received mail, and the mobile phone indicates that the received mail still has a continuation. When the user wants to read a continuation, the user operates a predetermined key of the operation unit 5 to scroll the screen so that the continuation can be read.

  Thus, by changing the window size according to the size of the received mail, it is possible to check the received mail with an appropriate screen size according to the display amount.

  The received mail display policy determination operation performed by the mobile phone 100 described above with reference to a specific example is organized as shown in the flowchart of FIG.

  That is, the control unit 1 attempts to specify the sender by referring to the address book 23 from the new received mail 25 stored in the storage unit 2. The control unit 1 also instructs the display unit 4 to notify the use of the liquid crystal display screen at the present time, and a mail is being created in the multi-purpose display area 414 based on the data received from the display unit 4. It is determined whether or not. When it is determined that no mail has been created, the control unit 1 causes the information related to the received mail to be displayed on the display screen 41 of the display unit 4 by any known method, and ends the process. On the other hand, when it is determined that the mail is being created, the control unit 1 specifies the scheduled addressee (step S111), and proceeds to step S113.

  When the sender cannot be specified, only the fact that the mail has been received from somebody is displayed on the display screen 41 in a manner according to the simple display described later.

  The control unit 1 determines whether or not the sender is the same as the scheduled destination (step S113).

  When it is determined that the sender is not the same as the scheduled destination (step S113; No), the control unit 1 determines to simply display the received mail (step S129), and ends the process. Here, the simple display is a simple mail reception notification display in the pictogram area 412 as shown in FIG. 8A, for example.

  When it is determined that the sender is the same as the scheduled addressee (step S113; Yes), the control unit 1 acquires the mail display size being created from the display unit 4 (step S115). The acquisition may be performed in advance in step S111.

  The control unit 1 uses the above-described formula (1) using the created mail display size acquired up to step S115, the created mail display minimum required size and the received mail display minimum required size stored in the storage unit 2. 1), the margin size is calculated (step S117), and it is determined whether the margin size is 0 or more (step S119).

  When it is determined that the margin size is not equal to or larger than 0 (step S119; No), the control unit 1 determines to simply display the received mail (step S129) and ends the process.

  When it is determined that the margin size is greater than or equal to 0 (step S119; Yes), the control unit 1 acquires a new received mail 25 from the storage unit 2 and performs a predetermined calculation to obtain the received mail full-text display size. (Step S121), and it is determined whether or not the obtained received mail full-text display size is larger than the received mail display minimum required size stored in the storage unit 2 (Step S123).

  When it is determined that the received mail full-text display size is not larger than the received mail display minimum required size (step S123; No), the control unit 1 determines to perform the short text received mail detail display (step S131). Here, “short text” implies that the entire newly received mail 25 is short enough to fit within the minimum required size of the received mail display, and “detail” herein refers to that in step S129. Unlike the case, it implies that the entire contents of the mail are displayed without being basically omitted. A specific example of step S131 is shown in FIG.

  If it is determined that the received mail full-text display size is larger than the received mail display minimum required size (step S123; Yes), the control unit 1 stores the created mail display size obtained up to step S115 and the storage unit 2 The received mail displayable size is obtained by the equation (2) by using the stored minimum required mail display size (step S125). Alternatively, the control unit 1 may calculate the received mail displayable size according to the equation (3) using the margin size obtained in step S117 and the received mail display minimum necessary size stored in the storage unit 2. Good.

  The control unit 1 determines whether or not the received mail full-text display size obtained in step S121 is larger than the received mail displayable size obtained in step S125 (step S127).

  When it is determined that the received mail full-text display size is not larger than the received mail displayable size (step S127; No), the control unit 1 determines to perform batch long received mail details display (step S133), End the process. Here, “collective” means that the contents of the newly received mail 25 can be displayed at once, and “long text” here is different from the case of step 131 in order to display the entire contents of the mail. It implies that the received mail display does not fit in the minimum required size. A specific example of this step 133 is shown in FIG.

  When it is determined that the received mail full-text display size is larger than the received mail displayable size (step S127; Yes), the control unit 1 determines to perform the long-text received mail detailed display with scroll bar (step S135). The process is terminated. A specific example of step S135 is FIG. 9B.

  The display modes determined in step S129, step S131, step S133, and step S135 can be classified into simple display and detailed display. That is, the received mail simple display (step S129) is a simple display, the short text received mail details display (step S131), the batch long text received mail details display (step S133), and the long text received mail details display with scroll bar (step S135). ) Is a detailed display.

  The display mode can also be classified from the viewpoint of whether the display on the display screen 41 related to the received mail is limited to a partial display or whether the entire text is displayed collectively. . That is, the received mail simple display (step S129) and the long-text received mail details display with scroll bar (step S135) are the former, and the short-text received mail details display (step S131) and the collective long-text received mail details display (step S133) are the latter. It is.

  As described above, the mobile phone 100 according to the present embodiment can change the interrupt display contents in accordance with the screen state, so that suitable information display can be performed in a limited screen area of the mobile phone.

  In particular, a display for displaying the received e-mail based on whether or not the e-mail creation screen is displayed when receiving e-mail, and the e-mail (size, destination, etc.) being created using the e-mail creation screen At least one of the area and the display content is controlled. Therefore, it is possible to easily and appropriately perform both the e-mail creation work and the received e-mail confirmation work.

  Further, based on the mail address and the registration information, it is determined whether or not the transmission destination of the email created on the email creation screen 416 matches the transmission source of the received email (step S113). Based on the result, at least one of the display area for displaying the received e-mail on the display screen 41 and the display content is controlled (S129 to S135). Therefore, it is possible to effectively prevent miscommunication by e-mail.

  In addition, the simplified display (S129) and the detailed detailed display (S131 to S135) are switched based on the registered name of the source of the received electronic mail and the registered name of the destination of the electronic mail being created. Compared to the case of comparing e-mail addresses, it is possible to suppress miscommunication. Further, since the display mode changes according to the other party, it is easy to check the e-mail.

  Also, the size of the e-mail creation screen 416 is determined (S115), and the display size of the received e-mail is determined based on the size (S119). If the possible size is less than a predetermined threshold, the received e-mail is displayed. The mail is simply displayed (S129), and if the possible size is equal to or larger than a predetermined threshold, the received electronic mail is displayed in more detail than the simplified display (S131 to 135). Therefore, it is possible to achieve harmony between the e-mail creation process and the e-mail confirmation process.

  Further, when the received email is displayed in detail, the size of the email creation screen is reduced, and a window for displaying the received email is displayed in a screen area vacated by the reduction (S133). Accordingly, it is possible to achieve harmony between the e-mail creation process and the e-mail confirmation process regardless of the size of the e-mail being created.

  Further, by setting the size of the window for displaying the received e-mail according to the size of the received e-mail data, the received e-mail can be easily confirmed.

  The present invention is not limited to the above embodiment, and various modifications and applications are possible. In the above embodiment, the storage unit 2 is built in the mobile phone 100.
