Description

  The present invention relates to a portable radio terminal such as a mobile phone having a mail function, and relates to a text layout technique for displaying a mail text on a liquid crystal display screen.

  Mobile phones with an e-mail function are widespread, and when a user performs e-mail communication with this terminal, the e-mail is displayed in an easy-to-read manner on the screen of the terminal device that is the e-mail destination. There are cases where the text of an e-mail is arranged by inserting spaces or line breaks on the screen of the terminal device. In this way, when the destination is a portable terminal device of the same model, a text of the same appearance as that confirmed on the screen of the source portable terminal device is displayed on the screen of the received portable terminal device.

  However, if the display function of the destination mobile phone differs depending on the type of communication company or mobile phone used, information may not be transmitted as intended by the mail creator. For example, due to the difference in the number of line feed characters due to the appearance of the liquid crystal display screen in the mail text and the difference in the character size, the image on the mail creation side may often be transmitted to the browsing side in a different form. In this case, the creation side is almost unaware and correction is difficult.

  2. Description of the Related Art Conventionally, various techniques for making a received mail easy to read in electronic mail transmitted / received between apparatuses having different display forms on the transmission / reception side have been proposed. For example, in Patent Document 1, wireless means for receiving character information, display character information storage means for storing character information received by the wireless means, and character information stored by the display character information storage means are analyzed and displayed. Display width adjusting means for adjusting the width, and display means for displaying the character information whose display width is adjusted by the display width adjusting means, and automatically displaying the display width of the character information of the line determined to require adjustment of the display width. By adjusting, line breaks caused by differences between models, etc., and line breaks such as punctuation marks and periods that should not be at the beginning of lines are eliminated.

  Further, in Patent Document 2, model information on the communication partner side is obtained and registered in advance in the mail address registration means for registering the mail address of the mail destination, and the model on the communication partner side is determined from the mail transmission destination address. E-mail display conditions are set, and the e-mail creation display condition setting means for setting the creation display conditions at the time of e-mail creation according to the obtained e-mail display conditions is provided. By creating a mail under display conditions, it is possible to display an electronic mail in a display format that is easy to read even with different types of receiving devices.

  In the case of the invention described in Patent Document 1, when displaying character information (email) on the display unit, it is possible to suppress line breaks of characters that should not be at the beginning of a line, such as punctuation marks, and only unnecessary line breaks and punctuation marks are broken. Since the situation can be avoided, misunderstood communication and reading difficulty resulting from line breaks when displaying character information can be eliminated, but for that purpose, the character spacing is reduced with respect to the previous line. There is a problem that it is necessary to perform control for shortening. Furthermore, in the invention described in Patent Document 1, it is not considered to determine the model (display function) on the transmission side from the received mail.

  In the case of the invention described in Patent Document 2, the model information of the communication partner is obtained and registered in advance, the model of the communication partner is determined from the mail transmission destination address, the mail display condition is obtained, and the communication partner is determined. E-mail transmission is performed in a display format that matches the model of the other side, so it is possible to display received e-mails in a display format that is easy to read even with different types of receiving devices. There is a problem that the model must be registered.

  An object of the present invention is to determine the mail display function on the transmission side from the received mail text on the receiving terminal side without registering the mail display function on the transmission side in advance, and to determine the mail display function of the own terminal. The object is to provide a means for enabling browsing of the imaged image of the transmission source by combining with the function.

  Another object of the present invention is to send a reply mail for the received mail with the determined mail display function, so that the reply mail having the image content can be transmitted without changing the mail display function of the sender. It is intended to provide a means for enabling display on a terminal.

The portable wireless terminal with a mail function having the received mail display part of the present invention analyzes the display position of the delimiter symbol when the received mail is displayed on the display part, thereby The transmission source display function determination means for determining the difference between the number of displayable characters and the number of display characters per line of the display unit of the transmission source mobile phone, and the number of display characters per line of the transmission source mobile phone When the number of displayable characters per line of the mobile wireless terminal is smaller, the display of the received mail is per line of the display unit of the transmission source mobile phone determined by the transmission source display function determination unit comprising a display setting change means for displaying in accordance with the display number, the source display function determination means, beginning from the first grid after the first sentence or Return mail thus received When at least one of the sentences to be determined is selected as a determination target and the selected sentence is displayed on the display unit, the position of the delimiter symbol such as the punctuation mark is the Nth line (N is an integer of 1 or more) of the sentence. The number of cells from the next cell of the delimiter symbol to the end of the line is n × N (n is an integer of 1 or more), and the next cell of the delimiter symbol When the next sentence of the received mail is continuously displayed, the number of display characters per line of the display unit of the mobile phone of the transmission source is 1 of the display unit of the mobile wireless terminal. It has a function of determining that there are n full-width characters less than the number of displayable characters per line .

  Specifically, the sender display function determination means analyzes the content (sentence) of the received mail, and uses the sentence end position such as punctuation marks and pictographs and the beginning position of the next sentence as a reference. If a deviation is found at the line feed position, it is determined that there is a mismatch between the transmission source and the number of display characters per line, and the display setting changing means displays one line so that the same display content as the transmission source can be displayed. It is characterized by having a function of correcting the contents as per the image of the transmission source so that the content can be viewed at the reception destination by automatically changing the number of characters displayed.

  Inconsistency determination of the number of display characters per line is made by selecting at least one of the first sentence of the received mail or the sentence starting from the first square after the line feed as a determination target, and the selected sentence is displayed on the display unit of the terminal. When the punctuation mark or pictogram symbol indicating the end of the sentence is displayed on the N line (N is an integer of 1 or more) of the sentence, the end of the line from the next square of the delimiter symbol is displayed. Up to n × N squares (n is an integer equal to or greater than 1), and the next sentence of the received mail is continuously displayed from the square next to the delimiter symbol. "The area that the display unit of the mobile phone of the mail sender can display on one line is fewer than n characters in full-width compared to the area that the display unit of the receiving mobile phone (own terminal) can display on one line." to decide.

  If the value obtained by subtracting the determined value n from the number of characters that can be displayed on one line by the display unit of the terminal itself is smaller than a predetermined value, the determination result is invalidated and the number of displayed characters The mail is displayed with the initial setting of the mobile phone (self terminal) (the number of characters that the display unit of the self terminal can display in one line) without performing change control.

  The portable wireless terminal with a mail function having the received mail display unit of the present invention stores the result of the determination by the transmission source display function determination unit in a memory in association with the transmission source mail address of the received mail. Means.

  When the user starts to create a transmission mail from the portable wireless terminal, the memory is searched for whether or not the result of the determination is stored in association with the destination mail address, and the input destination mail When the determination result is stored in association with the address, the determination result is read out from the memory, and the display setting changing unit is configured to match the determination result for each line of the display unit of the portable wireless terminal. Change the number of displayed characters.

  Accordingly, the outgoing mail input by the user from the key operation unit is created by the changed mail creation screen, and the data of the changed mail creation screen is transmitted to the destination mail address. On the display unit of the terminal, the same layout as that of the mail created on the modified mail creation screen is displayed.

  According to the present invention, the content of the email received by the mobile wireless terminal on the browsing side is analyzed, and the deviation of the line feed position from the creation side is found with reference to the position of the punctuation marks, pictographs and the like and the position of the beginning of the sentence. Because it is automatically corrected, when creating a mail, the appearance of the LCD screen on the composing side (sender) and the viewing side (recipient) is different, and the number of line feed characters differs depending on the character size setting. Even if it is impossible to convey the contents as it is, the mobile wireless terminal on the mail viewing side automatically includes a line break position that takes into account the appearance on the composing side before opening the mail to avoid it It becomes possible to do.

  FIG. 1 is an external view showing a mobile phone to which the present invention can be applied, and FIG. 2 is an internal block diagram showing a portion related to the present invention in the mobile phone shown in FIG. In addition to the block configuration shown in FIG. 2, the mobile phone also includes an antenna, a radio unit, an audio processing unit, a speaker, a microphone, and the like, but these configurations are not directly related to the present invention. Therefore, illustration is omitted in FIG.

  On the front surface of the cellular phone 1, there are a display unit 11 composed of a liquid crystal or the like having a function of displaying various messages, and a key operation unit 12 such as number keys used for text input by the user and menu keys for performing various settings. A battery 13 for supplying power is provided on the back side. The control unit 21 controls all the functions of the mobile phone 1. As control related to the present invention, when the character key of the key operation unit 12 is pressed, the character string is input, and the display unit 11, a control for reading out the contents of the memory 22 for storing a mail address, and a control for editing. The memory 22 stores programs for realizing various functions such as a call function and an e-mail function of the mobile phone 1, settings for executing various functions, etc., and also stores received mail addresses and received data such as mails. Various data such as temporary storage is stored.

  In the present embodiment, the control unit 21 analyzes the content of the mail received from the transmission source, and refers to the position of the beginning of the sentence and the position of the punctuation marks and pictogram symbols, and the display unit 11 of the mobile phone 1 (own terminal). When the received mail is displayed on the screen, it is determined that there is a discrepancy in the line feed position of the sentence, it is determined that there is a mismatch between the sender and the number of display characters per line, and the same display content as the sender can be displayed. Thus, the number of display characters per line is automatically changed.

  In determining the mismatch in the number of display characters per line, the control unit 21 selects at least one of the first sentence of the received mail or the sentence starting from the first square after the line feed as a determination target, and the selected sentence Is displayed on the display unit of the terminal, the position of a delimiter symbol such as a punctuation mark or a pictogram symbol indicating the end of the sentence becomes the Nth line (N is an integer of 1 or more) of the sentence, and the next to the delimiter symbol The number of squares from the square to the end of the line is n × N (n is an integer of 1 or more), and the next sentence of the received mail is continuous from the square next to the delimiter symbol "The area that can be displayed in one line on the display unit of the mobile phone from which the mail is sent is compared to the area that can be displayed in one line on the display part of the receiving mobile phone (self terminal). N full characters . It is determined that the ".

  Next, a specific example of the operation of automatically changing the number of display characters per line by the control unit 21 will be described with reference to FIG.

  Assume that the transmission source creates and transmits the example sentence of FIG. 3A on the mobile phone 1 capable of displaying 12 full-width characters per line. At this time, a punctuation mark indicating the end of the sentence is input in the last square (12th character) of the first line, but if a punctuation mark is input in the last square of the line, a line feed operation is not performed. Since the character input position automatically moves to the first cell on the next line, line feed input is omitted between this punctuation mark and the first character of the next sentence. On the other hand, when the display function of the receiving mobile phone 1 that received the mail shown in FIG. 3A is 13 characters in full-width per line, if the mail content is viewed without processing, the display for one full-width character is displayed. As shown in FIG. 3 (b), the display unit 11 of the receiving mobile phone 1 displays ".save" on the first line, so that the display form of the transmission source A discrepancy occurs in the display mode viewed by the recipient.

  Therefore, the control unit 21 analyzes the contents (FIG. 3 (b)) when the received mail content is displayed on the display unit of its own terminal having a display function of 13 full-width characters per line and analyzes the received mail. There is a punctuation mark “.” On the first line of the first sentence, and the first letter “storing” of the next sentence is entered in the last square of the first line, which is the next square of this punctuation mark Therefore, it is determined that the number of display characters per line of the display unit of the transmission source is one character less than the number of display characters per line (13 full-width characters) of the display unit 11 of the reception destination (own terminal).

  The control unit 21 associates the content determined from the received mail with the mail address of the transmission source as additional information and stores it in the memory 22. Based on the determined content, the number of display characters per line of the receiving destination (own terminal) is changed to the same setting as that of the transmitting source (FIG. 3C), and the content to be viewed at the receiving destination is transmitted. The content can be browsed in the same state as the original content (FIG. 3D).

  In the example shown in FIG. 3, the number of displayable characters (12 full-width characters) per line on the display unit of the transmission source is the number of displayable characters (13 full-width characters) per line on the display unit of the receiving destination (own terminal). However, for example, if the number of displayable characters per line on the display unit of the recipient (own terminal) is 14 full-width characters, the received mail displayed on the display unit of the own terminal In the last third cell of the first line, “.save” is displayed, and two characters of the next sentence are displayed after the punctuation mark. The number of displayable characters per line can be determined to be two characters less than the number of display characters per line (14 full-width characters) on the display unit 11 of the receiving destination (own terminal).

  Therefore, there is a punctuation mark “.” In the first line of the mail, and the number of characters (number of squares) that can be input from the next cell after the punctuation character “.” To the end of the line is n (n is 1 or more). And the next sentence is continuously input from the next cell after the punctuation mark “.”, The control unit 21 can display per line of the display unit of the transmission source. The number of characters can be determined to be n characters less than the number of characters displayed per line (14 full-width characters) on the display unit 11 of the receiving destination (own terminal).

  FIG. 3A shows an example in which a punctuation mark indicating the end of a sentence is input to the last square (12th character) of the first line. For example, the last square of the second line When a punctuation mark indicating the end of the sentence is input in (12th character), the display unit of the receiving terminal having a display function of 13 full-width characters per line is followed by a punctuation mark displayed on the second line. A character input area for the second square is generated, and the first two characters of the next sentence are input there. Therefore, the first sentence of the received mail is N lines, and the number of squares from the next square of the punctuation mark on the Nth line to the end of the line is N (N is an integer of 1 or more), If the next sentence of the received mail is continuously displayed from the next square of the punctuation mark, the control unit 21 determines the number of displayable characters per line on the display unit of the transmission source as the reception destination (own terminal). It is possible to determine that the number of characters displayed per line on the display unit 11 is less than one character.

  Further, in FIG. 3A, for example, a punctuation mark indicating the end of a sentence is input in the last square (12th character) of the second line, and 1 of the display unit of the receiving destination (own terminal). When the number of display characters per line is 14 double-byte characters, the character input area for the fourth square (2 characters × 2 lines) after the punctuation mark displayed on the second line in the display unit of the receiving destination (own terminal) Will occur, and the first four characters of the next sentence will be entered there.

  Accordingly, the first sentence of the received mail is N lines, and the number of squares from the next square of the punctuation mark on the Nth line to the end of the line is n × N (n and N are integers of 1 or more) ) And the next sentence of the received mail is displayed continuously from the next square of the punctuation mark, the control unit 21 determines the number of displayable characters per line on the display unit of the transmission source. It can be determined that there are n characters less than the number of display characters per line of the display unit 11 of (own terminal).

  In the example shown in FIG. 3, as shown in FIG. 3 (b), the first sentence of the received mail “Begin commuting by bicycle” is completed in the first line (N = 1) of the receiving side display section. Since the number of cells from the next cell after the punctuation mark “.” On the first line to the end of the line is 1, n × 1 = 1 and n = 1. Then, since the next sentence of the received mail “using the savings” is continuously displayed from the next square after the punctuation mark “.”, The control unit 21 displays one line of the display unit of the transmission source. The number of characters that can be displayed is determined to be one character less than the number of characters displayed per line on the display unit 11 of the receiving destination (own terminal).

  In the example of FIG. 3, the first sentence of the received mail is a sentence that can determine the number of characters, but for example, if there is a sentence that can determine the number of characters in the sentence starting from the first square after a line feed, It can be selected as a determination target. Also, if such a sentence that can be judged to be inconsistent in the number of characters is not found in the received mail, it is considered that there is no particular sense of incongruity with the display of the sender, so the initial setting of the receiving mobile phone The received mail is displayed as it is (the number of characters that the display unit of the terminal can display in one line). Even in this case, a sentence that can be judged to be inconsistent in the number of characters may be generated in the received mail while repeating the exchange of mail several times, so that the determination can be made at that time.

  Note that the display width of the display unit provided in the mobile phone is limited by the size of the mobile phone, and even if the number of display characters per line varies depending on the model of the mobile phone, the number of full-width displayable characters per line is It is about 10 to 15 characters, and usually the number of display characters within this range is adopted. Therefore, the value obtained by subtracting the determined value of n from the number of characters that can be displayed on one line by the display unit of the terminal itself is smaller than the value (for example, 10 characters) of the mobile phone having the smallest number of characters that can be displayed on one line. In the case of a small value, the display unit of the mobile phone from which the mail is sent is considered to have a larger number of display characters per line than the display unit of its own terminal. Without changing the number of display characters, the mail is displayed with the initial setting of the mobile phone 1 (the number of characters that the display unit of the terminal can display on one line).

  As described above, when the number of display characters per line is larger in the display unit of the mobile phone as the mail transmission source than in the display unit of the own terminal, the receiving terminal cannot perform the display character number change control according to the present invention. However, while repeating mail exchanges such as mail replies, the display character number change control of the present invention is performed by the mobile phone of the mail transmission source with a large number of display characters per line, so in the subsequent mail communication, there is a line feed error. Easy-to-read e-mail display can be realized.

  FIG. 4 is a flowchart showing the operation when the mobile phone of the present invention receives a mail.

  When the mail is received (S11), the control unit 21 confirms whether or not a learning function for executing the operation of the present invention for changing the number of display characters per line is set in the mobile phone 1 (S12). . If not set, the mail is opened and displayed on the display unit 11 in the initial setting of the mobile phone 1 (S18). Therefore, the user views the mail contents (FIG. 3B) displayed with the number of characters that can be displayed on one line by the display unit 11 of the mobile phone 1.

  When the learning function for executing the operation of the present invention is set, the control unit 21 selects and analyzes the sentence to be determined from the mail contents (S13), and determines that there is a line break. In the case (S14, YES), that is, the next cell of the character entered at the end of the sentence such as punctuation marks or pictogram symbols is the last cell of the first line, and the last cell of the sentence When the general character string that is input first is input, the control unit 21 indicates that “the display unit 11 of the mobile phone 1 that is the mail transmission source can display the area that the display unit 11 of the mobile phone 1 on the receiving side displays. Change to reduce the number of display characters per line by one full-width character so that it is the same as the display content of the image of the transmission source (see FIG. 3 ( c)) is executed (S15).

  At this time, the control unit 21 associates the changed content with the sender mail address and stores it in the memory 22 (S16). Therefore, the user can view the received mail contents with the setting in which the number of display characters is changed (FIG. 3D) (S17). On the other hand, if line breaks are not found, or if it is determined that the number of display characters per line is larger on the display unit of the mobile phone 1 that is the mail sender (S14, NO), the initial setting of the mobile phone 1 is performed. The mail is opened at (S18).

  Next, the control unit 21 automatically changes the number of display characters per line when the receiving terminal (own terminal) that has received the mail shown in FIG. A specific example will be described with reference to FIG.

  After receiving the mail shown in FIG. 3, when the receiving destination replies the mail to the transmission source during the learning function setting, the control unit 21 reads the learning content associated with the mail address of the reply destination and reads 1 The display setting of 13 full-width characters per line is changed to the display setting of 12 full-width characters (FIG. 5A), and the reply mail creation screen is opened. In response to the reply mail input from the key operation section 12, the control section 21 creates a reply origin mail on this creation screen (FIG. 5 (b)), so that the reply destination and the same number of display characters are aligned. You can send an email with the content. Therefore, in the mobile phone of the transmission source, the mail can be viewed with the same display contents of the reply destination (FIG. 5C) by the display function of the transmission source terminal.

  FIG. 6 is a flowchart showing an operation when the mobile phone of the present invention transmits mail.

  When the user of the mobile phone of the present invention starts to create a transmission mail (S21), the control unit 21 checks whether information associated with the input destination mail address is in the memory 22 (S22). If there is no associated information (S22, NO), the mail key-input by the user is created on the mail creation screen opened by the initial setting of the mobile phone 1 (S25).

  On the other hand, when the information associated with the input destination mail address is in the memory 22 (S22, YES), the control unit 21 reads the learning content associated with the destination mail address from the memory 22 and stores one line. The number of characters is changed to the number of displayable characters that the destination terminal has (S23). Therefore, the content of the email input by the user from the key operation unit 12 is created on the changed email creation screen (S24).
