BACKGROUND OF THE INVENTION
The present invention relates to an e-mail transmission / reception apparatus that displays an e-mail so that it can be efficiently read and written, and a display method thereof.
[0002]
[Prior art]
In electronic mail, it is possible to easily quote mail received at the time of mail creation. The quote part is distinguished from the normal part by adding a specific symbol such as “>” as a quote identifier at the beginning of the line. In some cases, the writer of the citation source can understand such as “Munetaka Yasunou wheat”. If this quoted part is displayed without being processed, there is a possibility that the listability of the mail is impaired. In particular, when displaying the contents of an email on a small display device, it is difficult to display the entire email.
[0003]
On the other hand, an example of processing a quoting portion in order to improve the listability is described in JP-A-10-207794. This display method is devised so as to improve the listability by displaying the entire quote part in a shaded display on the first line of the quote part or by reducing the display with an icon. It also describes a method of canceling the reduced display or returning to the original reduced display mode by touch input or key operation. However, with the above-described device, it is only possible to reduce / expand the quoted portion at once.
[0004]
Figure 4 is a mail with a plurality of reference portions is a diagram showing an example of a display screen of a mail that has not been reduced / decompression display. FIG. 11 is a diagram showing a display screen in which the mail shown in FIG. 4 is reduced / expanded by the method described in the above publication.
[0005]
In this way, when the citation section is divided into a plurality of parts as shown in FIG. 4, as shown in FIG. 11, only the entire display can be reduced / expanded as a whole. Some quoted parts are thin and do not affect context understanding even if they are displayed in a reduced size, while there are parts that should be expanded and displayed that are indispensable for context understanding. It is not possible to display the image in a reduced / expanded manner by distinguishing it as intended. In addition, since only the quote identifier at the beginning of the line is used to distinguish between the quote part and the normal part, a line such as “Munetaka Yasunou wrote” indicating the writer of the quote source is determined as the normal part. .
[0006]
[Problems to be solved by the invention]
The present invention has been made in view of the above-described problems of the prior art, and an object of the present invention is to enable reduction / expansion display of a quoted part as intended by an operator. It is another object of the present invention to enable a reduced display of a line representing a writer of a citation source in the same manner as a citation section.
[0007]
[Means for Solving the Problems]
In order to solve the above-described problem, the first technical means includes a transmission / reception unit that transmits / receives mail, a display unit that displays mail transmitted / received via the transmission / reception unit, and a display screen of the display unit on which the mail is displayed. And a control unit for controlling the display of mail on the display screen based on the instruction, and the instruction position indicated by the instruction unit on the display screen is displayed on the display screen. It is determined whether or not it is located on the line that displays the quoted mail with the quoted identifier specified, and if it is determined that it is located on the line that displays the quoted mail, the line before and after the judged line determines continuously in each row quoted identifiers are assigned so as to determine which rows quoted identifiers are assigned in a continuous as the reduced display range to display only the first line of the reduced display range was determined boss Shrink It is characterized by displaying.
[0011]
The second technical means is characterized in that the number of mail lines in the range to be reduced is displayed as the reduced display content.
[0012]
The third technical means is characterized in that the reduced display is expanded to the original display by indicating the line on which the reduced display content is displayed.
[0013]
The fourth technical means includes a transmission / reception unit that transmits / receives mail, a display unit that displays mail transmitted / received via the transmission / reception unit, and an instruction that indicates a predetermined position in the display screen of the display unit where the mail is displayed And a mail display in an electronic mail transmission / reception device comprising a control unit that controls display of mail on the display screen based on the instruction, the indicated position indicated in the display screen by the instruction unit determining whether located on the row to display the quote mail quoted identifiers displayed on the screen is attached, if it is determined to be located on the row to display the quotation mail, the determined row to determine in succession each front row and back row quoted identifiers are assigned, determining a line that quoted identifiers are assigned in a continuous as the reduced display range, determined Characterized in that it comprises a step of switching to display only the first line of the reduced display ranges.
[0015]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of an electronic mail display method and display switching method according to the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing an embodiment of a configuration of a terminal having a mail function to which the present invention is applied. In this figure, 1 is a central control unit (CPU) that controls the entire terminal, 2 is a software module that defines the operation of the central control unit 1, 3 is a display unit that displays emails to be sent and received, 4 is A transmission / reception unit for transmitting / receiving mails, 5 a data input unit for inputting mail data, 6 a pointing device for inputting mail contraction / expansion positions, and 7 for storing mail data. This is a data storage unit. Note that the data input unit 5 is not necessary in a terminal that does not have the function of inputting mail.
[0016]
2 and 3 are flowcharts showing an example of the processing procedure of the e-mail display method and display switching method according to the present invention. Here, the operation of the present invention will be described with reference to the flowchart of FIG .
[0017]
First, the point designated on the mail display screen by the pointing device 6 is detected (step S21), and the central control unit 1 calculates the line position and the digit position of the point position (designated position) (step S22). Here, the row position is a variable R, and the column position is a variable C. Next, the central control unit 1 determines whether or not the position is on the quote identifier based on the data stored in the data storage unit 7 (step S23). Since it performs, it transfers to step S31 of the following figure (FIG. 3).
[0018]
If not on reference identifier, the central control unit 1, subsequently, the display range indicating a reference source writers, or, it is determined whether the on display range of the right side (step S24), and on its scope If so, since some reduction display is performed, the process proceeds to step S36 in the next figure (FIG. 3). When the point position is not on the citation identifier, on the range representing the writer of the citation source, or on the right side of the citation identifier, the central control unit 1 is instructed in the data stored in the data storage unit 7 . A citation identifier is searched from the point position toward the beginning of the line (step S25).
[0019]
Next, it is determined whether or not a quotation identifier has been found (step S26). If it is found, some reduction display is performed, so the digit position C is changed here to the position of the found quotation identifier (step S27). ), The process proceeds to step S31 in the next figure (FIG. 3). If the quote identifier is not found in step S26, the process is terminated because the designated position is not within the mail display range to be switched to reduced display (step S28).
[0020]
Next, processing for determining a mail part to be reduced and displayed will be described with reference to the flowchart of FIG. If the indicated point position in Step S23 in FIG. 2 on the reference identifier, and a step 26, reference identifier is searched at step S27 in the processing after the transition to FIG. 3, first, the row position R as described above Since the position of the digit position C is on the quote identifier, when the symbol of the quote identifier is a multi-byte symbol such as “>” (double-byte symbol) , the central control unit 1 determines the digit position C. the changes at the beginning side in the reference identifier (symbol) (step S31). Next, the central control unit 1, only the row position of the digit position C to the left, R-1, R-2 ,. . . Then, the line position while the digit position C is the quote identifier is decremented (moved upward) (step S32).
[0021]
If the row reference identifier is attached in the digit position C is exhausted continuously, further, there is determined whether the display range indicating the reference source description (Step S33), if so The line position is further decremented by 1 (step S34). Thus row position of the beginning of a sentence side mail part to shrink display Ru is determined (step S35).
[0022]
Next, similarly, the central control unit 1 keeps the column position C as it is and sets only the row position to R + 1, R + 2,. . . Then, the row position where the corresponding position is the quote identifier is incremented (moved downward) (step S36). Thus incremented to a range of rows quoted identifiers sequentially to the digit position C is searched, endnotes side row position of the mail part to shrink display Ru is determined (step S37).
As described above, when a quote identifier is searched in S25 and S26 for the line of the pointed indication position, the digit position C indicating the position in the line of the quote identifier is specified in S27 and S31, and in S32 to S37. A continuous range of lines with a quote identifier added to the column position C is specified in the lines before and after the line, and a range to be reduced and displayed is determined.
[0023]
Finally, when the central control unit 1 reduces and displays the mail part to be displayed in a reduced size determined in step S35 and step S37, it simultaneously remembers from which line to which line of the mail the reduction is reduced ( Step S38). When the process proceeds from step S24 in FIG. 2 to the process of determining the mail part to be displayed in a reduced size shown in the figure, the process immediately proceeds to step S36. This process is almost the same as the process in the case of proceeding to the flowchart of this figure in step S23 and step S27, and there is no process (steps S31 to S35) for searching for the mail part to be reduced and displayed on the sentence head side. Therefore, explanation is omitted. This algorithm does not correspond to the case where there is a gap line between the line representing the writer of the citation source and the corresponding quote part, but it may be adapted to this case.
[0024]
Next, an embodiment of the present invention will be described with examples. As shown in FIG. 4, the quoting part shown in FIG. 4 can be implemented in the configuration of the terminal shown in FIG. 1 as compared with FIG. 11 which is a reduced display according to the conventional example. An embodiment of the present invention will be described. FIG. 4 shows a state in which the received normal mail is displayed on the display unit of 13 rows vertically, and the quote part occupies most of the screen, and the full text of the mail cannot be displayed.
[0025]
FIG. 11 shows a display screen in which the mail shown in FIG. 4 is displayed by the above-described method for reducing the quoted portion at once. Unlike FIG. 4, the mail can be displayed up to the end of the mail. The time information that should have been in the quoted part of the eye cannot be displayed. FIG. 5 is a view showing an example of a display screen obtained by performing the reduction / expansion display method according to the present invention on the mail body shown in FIG. As shown in the figure, to collapse the first reference portion of the mail shown in FIG. 4, which extends displaying a second reference part, similar to the mail text shown in FIG. 11, is displayed to the mail end The time information in the second quotation part can also be displayed. Thus, by providing the user with a method capable of changing the reduced / expanded display for each quoted part, it is possible to display an e-mail having both listability and detailed display.
[0026]
Next, in this embodiment, a method for switching between the reduced / expanded display of the citation part according to the present invention will be described.
FIG. 6 is a diagram showing a screen in which a range in which a pointing device is pointed by the pointing device in order to switch to the display of FIG. 5 is superimposed on the mail text display screen of FIG. When the range enclosed by the solid line in FIG. 6 is pointed, the first digit quote identifier “>” is searched in steps S21 to S26 in FIG. 2, and the first digit quote identifier is searched in S27 and S31. The digit position C is specified, and in S32 to S37, the continuous range of lines in which the quote identifier is attached to the digit position C surrounded by the solid line shown in FIG. The screen is switched to the reduced display screen shown in FIG. FIG. 7 is a diagram showing a screen in which a pointing device point range for switching to the original mail text display screen shown in FIG. 4 is superimposed on the display screen of FIG. The Rukoto to point instructs the range surrounded by the solid line, the display of FIG. 5 is switched to the extended display screen shown in FIG. In this example, the point range for reduction is applied up to the blank at the right end of the display, but it can be limited to only the character string portion of the mail body or the quote identifier portion . In addition, although the range in which the point for expansion is designated is only the portion representing reduction, it can be extended to the blank at the right end of the display. The display switching is not completed only by the point instruction operation, but can be combined with other operations.
[0034]
Next, a method for defining the range indicating the citation source writer will be described. The display of the writer of the citation varies depending on the mail software and the user settings for the mail software, such as “Munetaka Yasunou Wrote” and “Munetaka Anno wrote:”. Therefore, it is only necessary to store these fixed sentence formats as a dictionary in the terminal so as to define the range indicating the citation source.
[0035]
FIG. 8 is a diagram illustrating an example of a dictionary that lists formats of fixed phrases stored in the terminal. At this time, the format of the fixed phrase may be additionally input by the user, or may be downloaded from the outside via the transmission / reception unit. As an example of the format specification, a method using a regular expression can be considered. In the above embodiment, when the quotation part is displayed in a reduced size, the first line of the reduced range is represented by shading to indicate the range, but the mail data including other than the first line of the reduced range is displayed. The display contents at the time of reduction may be determined based on the original. Then, the user may be able to set which expression is to be performed.
[0036]
FIG. 9 and FIG. 10 are diagrams showing display examples showing a reduced display portion when such a quote portion is displayed in a reduced size. FIG. 9 shows a reduced display equivalent to that shown in FIG. 5 according to the number of lines and the number of characters reduced based on the line range of the mail to be reduced stored in the process of S38 as described in FIG. This is an example when a reduced portion is represented. FIG. 10 shows an example in which a reduced portion is represented by a writer of the reduced range with the same content as that shown in FIG.
A combination of these display methods is also conceivable. As described above, the present invention may be applied not only when viewing electronic mail but also when creating mail.
[0037]
【The invention's effect】
According to the present invention, it is possible to display an electronic mail having both listability and detailed display. Specifically, reduction / expansion display of a plurality of citation portions can be switched independently, or reduction / expansion display of a mail that has been quoted a plurality of times can be partially switched. Further, it is possible to reduce / expand the range in which the writer of the citation source is displayed in the same manner as the citation section. Furthermore, the display contents at the time of reduced display can be determined flexibly.
