Abstract

PROBLEM TO BE SOLVED: To improve the power of expression of characters by changing the display color or character size only of a designated character string in a mail text by validly using a color LCD. SOLUTION: Character strings surrounded by special characters are defined so as to be replaced with a Compact-HTML tag designating color display corresponding to the kinds of the special characters by the browser of a portable telephone. For example, the designation of the red display of the special character ' ' or the designation of the blue display of the special character [ ] is preset. As for a mail sentence 2 displayed in a display 1 of a reception side portable telephone, '10:00 am, today' is shown in red display 3, and [that park] is shown in green display 4, and the other clauses are displayed in a normal color. Thus, the significant information such as a time and place is color- converted so that the a receiver can carefully read those color-converted character strings. Also, those ' ' or [ ] surrounding the color-converted character strings of the mail sentence 2 is excluded from the target of color conversion, and the display of those parentheses is erased after the character strings are color-converted.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a portable terminal capable of transmitting and receiving character information such as mail, and more particularly to a portable terminal capable of improving the expressiveness of displayed character information.

[0002]

2. Description of the Related Art In recent years, a mobile phone capable of sending and receiving e-mails has recently come to be equipped with a color LCD (L / L) supporting a mail function.
The iquid Crystal Display) type has begun to be sold. Such a mobile phone that supports the mail function usually uses a compact dedicated browser, and the HTML specification for the mobile phone (so-called Compact-HT) is used.
By specifying the tag of (ML), the display color can be easily changed by the browser. That is, by tag specification,
The entire display can be changed to a desired display color.

[0003]

However, in a mobile phone equipped with a conventional color LCD, it is not possible to color and display only words and phrases that are particularly impressive to the other party in the contents of the mail text. In other words, the mobile phone has a smaller LCD than a normal personal computer, and has a limited memory capacity and the number of keys. Therefore, when inputting e-mail text, it is necessary to specify colors in the same way as a normal personal computer. It is difficult to do. Therefore, with the current mobile phone, the entire text of an e-mail can be displayed in a desired character color, but the color of only a limited character string cannot be changed.

The present invention has been made in view of such circumstances, and it is an object of the present invention to effectively use a color LCD to change a display color of only a designated character string in a mail text. An object of the present invention is to provide a mobile terminal such as a mobile phone that can improve the expressiveness of characters by changing the character size.

[0005]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention relates to a portable terminal for receiving and displaying character information.
A detection unit for detecting the special character,
A color change control unit for changing and controlling a character string surrounded by the detected special characters to a designated color predetermined for each of the special characters, and a deletion unit for deleting the detected special characters is provided. And

Therefore, according to the portable terminal of the present invention,
By enclosing a part of the text (that is, a character string) in the mail text with special characters, the enclosed character string can be easily displayed in a different color from the standard color.
Note that the special characters used at this time are special characters and symbols that are different from the Japanese syllabary or alphanumeric characters and are commonly used in ordinary sentences. By using such special characters, it is not necessary to add a special function for a new text input operation. That is, a designated color to be converted corresponding to each type of special character is determined in advance for the mobile phone, and the caller terminal phone inserts a desired character string when creating a mail text. Insert special characters. On the other hand, the receiving terminal telephone reads the input characters and converts only the character string surrounded by the special characters into a designated color corresponding to the special characters.

That is, a specific method of operating the mobile phone is as follows. In the mobile phone on the sender side, predetermined special characters are inserted before and after a character string to be color-coded in the displayed mail text. Send. Then, on the recipient's mobile phone, only the character string surrounded by special characters in the received mail text is changed to the specified color corresponding to the type of special character, and the entire mail text is displayed Is done. In addition, by inserting a plurality of types of special characters designated to change colors for each character string, individual character strings in the entire character information can be displayed in different colors for different purposes. In this manner, by displaying the individual character information in the mail text in different colors, the expressiveness of the character information can be improved. That is, within the entire character information,
Only the character string that calls attention to the recipient or strongly impresses can be expressed in different colors.

Further, the present invention provides a portable terminal for receiving and displaying character information, wherein, when the received character information has two or more predetermined special characters, a detecting means for detecting the special characters; Character strings surrounded by special characters
A character size change control unit that controls change to a predetermined character size for each special character and a deletion unit that deletes the detected special character are provided.

That is, the portable terminal according to the present invention does not display a character string surrounded by special characters by color conversion, as in the above-described invention, but converts a character string surrounded by special characters into a normal character size. Is converted to a different character size.
As described above, even if the character size of only the character string to be emphasized to the receiver side is changed (for example, increased), the expressive power of the character information can be improved.

[0010]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to a portable telephone as an example. In the mobile phone of the present invention, the sender's mobile phone does not need to perform troublesome input designation or setting when inputting the text of an email. Alternatively, a special character predetermined for each designated color may be inserted on both sides of a character string such as a sentence content to be strongly impressed. That is, the caller's mobile phone first prepares a normal text, and then transmits a character string whose color is to be emphasized by changing the color with special characters defined for each designated color. The special characters to be input at this time are, for example, various parentheses such as "", [], [], and parentheses, and characters and symbols such as #, &, and ￥.

[0011] On the other hand, when the receiver's mobile phone receives the text of the e-mail and detects a special character, it automatically starts up a browser and sets a character string surrounded by the special character in advance for each special character. Is converted to the specified color and displayed. Therefore, in the mail text, a character string not surrounded by special characters is displayed in a normal character color without color conversion, and a character string surrounded by special characters is converted into a desired character color and displayed.

In the portable telephone according to the present invention, the target information to be displayed with the character color changed is a title of a mail, a part of a word or a sentence in the text, or the whole sentence.
In addition, special characters that change the character color can be inserted at a plurality of places in one mail text, and different character colors can be displayed for each type of special character. Therefore, in one email text,
If necessary, several types of colors can be displayed.

For example, the special character "" is designated in red, the special character [] is designated in blue, the special character [] is designated in green, and the special character "" is designated in purple. If you do,
The character string between "Iroha" is displayed in red, the character string between [Hohei] is displayed in blue, the character string between [Chirinu] is displayed in green, and the character string between "Naramu" is purple Is displayed with. Usually, special characters () are sometimes used for displaying a telephone number or the like. In such a case, the special characters () cannot be used for color conversion.

That is, as a setting function of the browser, when a leading special character in a character string is detected, color conversion to a designated color corresponding to the special character is started, and then a special character of the same type is detected. It is set so that the color conversion ends when it is done. With this setting, the browser automatically converts the character string within the range of the special character into a color character corresponding to the special character and displays the character string.

Next, a specific example of a mail text will be described. I'm waiting at the "Normal Park" at "9:00 today".
Don't be late! Is sent from the sender's mobile phone, the display on the receiver's mobile phone shows 9 o'clock in red text today,
Is displayed in green text color. Such a process of changing the character color can be implemented in the browser, or can be converted outside the browser and passed to the browser. In either case, the caller ’s mobile phone ’s transmission history
The text after each color conversion can be saved.

FIG. 1 is an example of a screen which is color-coded and displayed by a received mail in the mobile phone of the present invention. In FIG. 1, a display 1 displays a mail text 2 together with a received mail, a sender, a reception date and time, and a title. Email 2 is waiting at {10:00 am today} at {Example Park}. Don't forget to bring your promise! It has become. At this time, “10:00 am today” is displayed in red 3, {example park} is displayed in green 4, and the other phrases are in standard color. As a result, the receiver can carefully read the color-converted character string of the time and place as important information. Note that "" and "@" surrounding the color conversion character string of the mail text 2 are not subjected to color conversion, and the display of these parentheses disappears after the character is color-converted.

The special characters "", [], and [] can be within the range of a character string whose color is to be changed, or can be within the range of a character string whose color is not to be changed. In the above example, the range of changing the color is set.If the range of the special character "" is set to the range of the character string that does not change the color, for example, in the case of an e-mail sentence "Be careful" in a strong wind Is displayed in red text color in strong winds, and is displayed in a standard color with no color conversion as noted. After being displayed in the designated character color, the inserted special character can be automatically erased or can not be erased. However, since the expressive power is usually improved by the color conversion of the characters, it is desirable to set so that the special characters are automatically erased.

Next, the flow of processing when the receiving-side mobile phone performs color conversion of mail text will be described with reference to a flowchart. FIG. 2 is a flowchart showing a flow of processing when the receiving mobile phone performs the color conversion of the mail text shown in FIG. In the figure, first, the mobile phone on the receiving side determines whether or not a mail has been received (step S).
1). If an e-mail has been received (step S1,
YES), it is determined whether or not the mail text contains two or more special characters (step S2). If two or more special characters are not included (step S2, NO), a normal mail display is performed on the display (step S3).

On the other hand, if two or more special characters are included in step S2 (step S2, YES), the special character is detected (step S4), and the detected special character and the special character A comparison is made with a color conversion table in which the designated color is recorded (step S5). Then, the character string surrounded by the special characters is color-converted according to the color conversion table (step S6). Next, the detected special character is deleted (step S7). Then, only the designated character string is color-converted and the entire text of the mail text is displayed on the display (step S8).

Further, as another embodiment, by defining a display specification when special characters "", [], and [] are nested, it is possible to cope with more complicated display. For example, it may be set so that each type of parenthesis is switched to the designated color for each start mark and returned to the previous designated color for each end mark. That is, "is converted to red display, [is converted to blue display, and [is converted to green display.
Then,] returns to blue display,] returns to red display, and returns to the standard color.

As an example of an e-mail, "Today at 9 o'clock,
[Wait at the example park. [Mr. XX will come.] Bring an example, and please come in time. Xx
At 9 o'clock today, when I receive the e-mail, I wait in the park, which is displayed in red. Is blue, xx will come, so please bring the green one, bring the example, and blue, please come in time. Indicates a red color, and XX indicates a standard color.

Also, each time a special character of each type is switched, the RGB of the display color designated for the new special character is changed.
The value of (Red Green Blue) and the value of RGB of the display color designated for the special character before switching can be taken as the larger value and displayed as a new RGB value. Alternatively, the smaller RGB value of the two may be taken and displayed as a new RGB value, or the average of the two RGB values may be taken as the new RGB value.
It is also possible to display as a B value and sequentially switch display colors. For example, it is also possible to return the display to the standard color with "" to display red, [to display the intermediate color of red and blue, and] to return to red, and "".

As special characters, besides "", [] and [], <>,! , “, ', ♯, ♯, ＄,%, &, ￥, etc. can also be used as enclosing characters. By using these various special characters, you can not only change the character color, but also For example, as long as the display can be performed by specifying the tag, the background color and the character size can be switched and displayed.
For example! 2! To specify the maximum font size
If it is defined to be replaced with a t-HTML tag,
The character size of the numeral 2 can be arbitrarily changed. Furthermore, if {3} is defined to be replaced with a Compact-HTML tag that switches the background display color to blue, the background display color of the numeral 3 can be changed to blue.

[0024]

As described above, according to the portable terminal (for example, a portable telephone) of the present invention, the character color of a phrase or a phrase to be emphasized or called for attention is changed or the character is changed in the mail text. It can be displayed in different sizes. Therefore, the e-mail can be easily viewed and the intention of the sender can be accurately communicated to the other party. An input operation for changing a character color or a character size can be realized by inputting a special character which is usually used. Therefore, it is not necessary to add a function for performing special processing, and color conversion of an input mail can be easily performed without providing an external keyboard, an external display device, or the like. Furthermore, even when the other party replies to the mail, the text of the mail can be displayed in the same color as when the text was sent to the other party.
