  In the body data description part, text data constituting the mail text is described in association with an HTML (Hypertext Markup Language) tag for each sentence. Each HTML tag is further associated with information specifying the font size and character color of the characters constituting the corresponding sentence, and information defining the placement of each sentence (left alignment, centering, right alignment, etc.). When the e-mail includes an image, information for identifying the data of the attached image is described in the body data description portion in association with the HTML tag.

  In the attached file data description portion, image data attached to the e-mail is described. Each of these image data is described in a GIF (Graphic Interchange Format) format, and includes image size data indicating the vertical and horizontal widths of each image in addition to the control information for each pixel forming the bitmap. Yes.

  Next, an e-mail transmission process (FIG. 4) and an e-mail display adjustment process (FIG. 6) according to the present embodiment will be described. In the present embodiment, it is assumed that the mobile communication terminal 50A transmits e-mail data created on its own as shown on the left side of FIG. 5 to the mobile communication terminal 50B. For convenience of explanation, it is assumed that the display unit 52 of the mobile communication terminal 50A has a display area with a width of 240 pixels, and the display unit 52 of the mobile communication terminal 50B has a display area with a width of 144 pixels.

  Note that the width of the display area included in the display unit 52 is not limited to this, and can be any value indicating the width of the display area that the mobile communication terminal 50 would normally have. In the present embodiment, it is assumed that the horizontal width of the display area of the mobile communication terminal 50A is larger than that of the mobile communication terminal 50B. On the contrary, the mobile communication terminal 50B has a larger display area. Of course there may be.

  FIG. 4 is a flowchart showing an e-mail transmission process executed by the control unit 55 of the mobile communication terminal 50A. When the user performs an operation for creating and sending an e-mail on the operation unit 51, the control unit 55 reads out and executes the mailer application from the nonvolatile memory 54b, and can provide it to the user according to the mailer application. A menu screen that is a list of functions is displayed on the display unit 52. Subsequently, when the user selects a new mail creation function, the control unit 55 starts the email transmission process shown in FIG. 4 according to the mailer application.

First, the control unit 55 creates e-mail data in accordance with the operation of the operation unit 51 performed by the user, and displays the content of the e-mail on the display unit 52 (step S101). In this step, when the user inputs the body of the e-mail by operating the operation unit 51 and performs an editing operation such as selection of the font size or character color of the body, placement of characters such as centering, the control unit 55 In accordance with the input work and the edit work, a text description part of the e-mail data is constructed. When the user inputs a transmission destination address by operating the operation unit 51, the transmission destination address is written in the transmission source address description part of the e-mail data. Further, when the user selects a desired image and embeds it in the e-mail, the corresponding image data is read from the nonvolatile memory 54b and stored in the attached file description portion of the e-mail data. The user can also perform arrangement processing such as centering on these images.
In the present embodiment, it is assumed that an e-mail as shown on the left side of FIG. 5 is created in step S101. As shown in the figure, in this e-mail, images A, B, and C are arranged left-justified, centered, and right-justified, respectively.

After visually recognizing the display state of the e-mail on the display unit 52, the user inputs a destination of the e-mail (in this embodiment, the address of the mobile communication terminal 50B) and presses a send button (not shown).
Next, in step S103, the control unit 55 receives a mail transmission instruction from the user. The control unit 55 that has received this transmission instruction reads the display size information stored in the nonvolatile memory 54b in step S105. This display size information is information indicating the horizontal width (240 pixels) of the display area of the mobile communication terminal 50A, and is hereinafter referred to as “display size information A” for convenience of explanation.

Subsequently, the control unit 55 writes the display size information A in the display size information description part in the header of the e-mail and writes the e-mail address of the own device in the e-mail data as the transmission source address (step S107). The electronic mail is transmitted via the wireless communication unit 53 (step S109).
The mobile communication terminal 50B receives the electronic mail transmitted from the mobile communication terminal 50A via the mobile communication network 40. The control unit 55 of the mobile communication terminal 50B notifies the user that the electronic mail has been received and stores the electronic mail data in the nonvolatile memory 54b.

FIG. 6 is a flowchart showing an e-mail display adjustment process according to the present embodiment.
When an operation for instructing browsing of electronic mail is performed by the user, the control unit 55 of the mobile communication terminal 50B reads the electronic mail data instructed to be browsed from the nonvolatile memory 54b. Thereafter, the control unit 55 starts the e-mail display adjustment process shown in FIG.
In step S201, the control unit 55 first reads the display size information A (240 pixels) of the mobile communication terminal 50A with reference to the display size information description unit of the read e-mail data. Next, the control unit 55 reads display size information (hereinafter, “display size information B”) stored in the non-volatile memory 54b of the own device (step S203). In the present embodiment, the display size of the mobile communication terminal 50B is 144 pixels.

Next, the control unit 55 calculates the ratio of the display size information B to the display size information A (step S205). As a result, in this embodiment, the scaling factor 144/240 is obtained.
In step S207, the control unit 55 refers to the text data description unit to determine the layout of the text data, and then arranges the sentence associated with each HTML tag at a predetermined position. Thereafter, the routine proceeds to step S209.
Next, the control unit 55 reads the data of the attached images A, B, and C with reference to the attached file data description unit (step S209), and specifies the aspect ratio of each image (step S211). Thereafter, the image a, b, c is subjected to the size changing process by applying the scaling ratio 144/240 obtained in step S205 to each of the images A, B, C while maintaining the specified aspect ratio. Is generated (step S213).

  In step S215, the HTML data associated with the images A, B, and C before the size changing process is referred to in the body data description unit, so that each image is arranged. Specifically, the image a is left-aligned, the image b is centered, and the image c is right-aligned. As a result, as shown on the right side of FIG. 5, the e-mail is displayed in a suitable size and arrangement (step S217). The e-mail display process in FIG.

  According to the embodiment described above, when a transmission instruction is given to the mobile communication terminal 50B after an e-mail including an image is created in the mobile communication terminal 50A, the display size information of the mobile communication terminal 50A is automatically added. And sent as part of the e-mail data. For this reason, the mobile communication terminal 50B that has received the e-mail obtains a scaling factor based on the display size of the mobile communication terminal 50A that is the e-mail creator terminal and the display size of its own device, and is attached to the e-mail. Can be displayed with the ratio of the display screen to the image kept the same as that of the mobile communication terminal 50A. As a result, it is possible to display an e-mail on the display unit of the receiving terminal in a state almost the same as the state visually recognized by the user of the transmitting terminal immediately before the transmission instruction.

In addition, when the ratio of the vertical width and the horizontal width of the display area is different between the sending terminal and the receiving terminal of the e-mail, even if the image resizing process using the display information indicating the width of the display area is performed, the e-mail It is possible that the lower part of the screen protrudes from the screen. In such a case, the user can view an e-mail laid out in a suitable size in the horizontal width direction by performing a very easy operation of scrolling the screen in the vertical width direction of the display unit.
In the present embodiment, the image size changing process is performed based on the display size information indicating the horizontal width of the display area of the transmission side terminal and the reception side terminal. If the size changing process is performed using the scaling factor, the user does not need to scroll the screen, and the entire e-mail can be viewed at a glance.

(Second embodiment)
In the first embodiment, the image size changing process is performed. In the present embodiment, a case will be described in which the character size changing process is performed in addition to the image size changing process. In this embodiment, the same reference numerals are used for portions common to the first embodiment, and the description thereof is also omitted.

  The mobile communication terminal 50 according to the present embodiment is different from the mobile communication terminal 50 according to the first embodiment in that character data corresponding to a plurality of types of font sizes is stored in the nonvolatile memory 54b. Specifically, the mobile communication terminal 50 according to the present embodiment stores five font sizes of 7, 9, 12, 14, and 18 points as bitmap font data. After the scaling ratio is determined based on the display size information of the mobile communication terminal 50A and the mobile communication terminal 50B, a font size that matches or is closest to the scaling ratio may be selected to change the character size. It becomes possible.

  For example, in the example of FIG. 5, it is assumed that “Dear Ken” and “Lisa” are both described with a font size of 12 points, and “Happy Birthday!” Is described with a font size of 18 points. Since the scaling factor obtained by the processing of the first embodiment is 144/200 (= 60% reduction rate), “Dear Ken” and “Lisa” are 12 × 60% = 7.2 points, “Happy Birthday!” 18 × 60% = 10.8 points are obtained, and the font size corresponding to the most approximate value is selected from a plurality of types of font sizes stored in the mobile communication terminal 50A. In the example of FIG. 5, a font size of 7 points is selected for “Dear Ken” and “Lisa”, and a font size of 12 points is selected for “Happy Birthday!”, And each character string is displayed in the selected size.

  The characters whose size has been changed in this way are respectively arranged according to the position associated with each HTML tag after the layout of the text data is determined by the control unit 55 in S207 of FIG. Specifically, in FIG. 5, “Dear Ken” is arranged left-justified, “Happy Birthday!” Is centered, and “Lisa” is arranged right-justified. As a result, the display screen of the mobile communication terminal 50B, which is the receiving terminal, has a balance between images and characters in the same state as that displayed on the display screen of the mobile communication terminal 50A, which is the e-mail creator terminal. An e-mail message is displayed that has been kept.

  The type of font size held by the mobile communication terminal 50 is not limited to the above five types, and can be arbitrarily changed. For example, the character size according to the present embodiment based on the font size associated with a name that can be easily recognized by the user, such as “minimum”, “small”, “slightly small”, “medium”, “large”, “extra large”, “maximum”. The change process may be performed. This makes it possible to improve the visibility by appropriately changing the font size to “small”, for example, when the user of the receiving terminal feels it is difficult to visually recognize the characters reduced to “minimal”. Become.

(Modification)
As mentioned above, although embodiment of this invention was described, this invention is not limited to such embodiment, For example, it can consider changing as follows.
(Modification 1)
In the first embodiment, the image size is changed based on the scaling factor obtained from the display size information of the transmission side terminal and the display size information of the reception side terminal.
However, there may be a case where the visibility of the image is remarkably lowered by performing the size changing process based on the scaling factor. For example, if the image C in FIG. 5 is image data including small characters such as initials and marks, for example, if the image C is reduced using a scaling factor of 144/200 (= 60% reduction rate), the image There is a risk that the characters contained in will be unrecognizable.

In such a case, when reducing an image whose original image size is smaller than a certain size, the scaling factor obtained from the display size information of the transmitting terminal and the display size information of the receiving terminal is not applied as it is. For example, a configuration in which a reduction ratio of 4/5 is uniformly applied may be adopted.
Similarly, the character data may be configured to apply a reduction ratio of, for example, 4/5 for characters smaller than a certain size.
This makes it possible to display an e-mail message in a form as close as possible to the display state on the transmitting terminal while ensuring visibility even in a limited display area of the mobile communication terminal.

(Modification 2)
In the above-described embodiment, the case where the mobile communication terminal 50 is a mobile phone having a mail client function has been described. (Personal Digital Assistance), a mobile PC having a mail client function, or the like may be used. This mobile communication terminal has one or more of a call function, a data communication function, and a vertical scroll function.
Further, the mobile communication terminal 50 according to the present invention is not limited to the mobile communication terminal 50 accommodated in the mobile communication network 40 as described in the above embodiment. It may be a terminal accommodated in the communication network.

(Other variations)
In the above-described embodiment, the display adjustment application has been described as being stored in advance in the nonvolatile memory 54b. However, the application described in the Java (registered trademark) programming language is stored in the server device on the network. The application may be appropriately distributed in response to a request from each mobile communication terminal 50 for the server device, and may be executed on the Java virtual machine of the mobile communication terminal 50.

  In the above embodiment, the “display” should be interpreted in a broad sense, such as an electronic display (not limited to an LCD) and an optical display (not limited to a projected image).

  The image data in the above embodiment has been described as being described in the GIF format, but may be described in another format such as JPEG (Joint Photographic Experts Group).
