Description

  The present invention relates to communication of character information and display of received character information in a mobile phone or the like.

  2. Description of the Related Art Conventionally, it has become possible to access e-mails and Internet web pages in addition to normal calls using a mobile phone or the like. Information from these e-mails and web pages includes character information, and the character information is communicated by a predetermined character code. The mobile phone stores a table of character codes and font data corresponding to the character codes, and displays characters using this table.

  Here, in Japanese mobile phones, a table of Japanese fonts is stored to display Japanese characters, and Japanese can be displayed. As for the alphabet, every mobile phone in the world has a table for fonts.

  Here, mobile phones other than Japan basically do not have a table for Japanese fonts and cannot display Japanese. On the other hand, the Internet is accessible from all over the world and is borderless. Therefore, there is a demand for displaying Japanese on overseas mobile phones.

  Therefore, there are attempts to realize this, and some have been realized. In this method, characters are transmitted as images and displayed as Japanese on the screen of the mobile phone. That is, in the case of image information, the basic is data for each dot, and if all of the data is image data, no character code is used, so no font or the like is required and character display can be performed. There are several types of methods for converting a character into an image, but the information that is communicated and the information that is displayed are the image itself.

JP 2000-163204 A

  The image data has a large amount of data and takes a long time to communicate. On the receiving side, there is a problem that image data for one screen is a unit and editing for each character cannot be performed at all.

  In a personal computer or the like, since there is a sufficient storage capacity, it is sufficient to store necessary font data and switch languages. Such a method is described in Patent Document 1, for example.

  The present invention provides more convenient communication for various languages.

  An information providing method according to the present invention is a character information providing method for providing character information to a terminal device via a communication network. When providing character information to a terminal device, a character code and a dot corresponding to the character code are provided. It is characterized by transmitting font data composed of maps in pairs.

  In addition, the present invention is a server that is connected to a communication network to which a plurality of terminal devices are connected and provides character information to the terminal device, and is a font data comprising a character code and a dot map corresponding to the character code. A terminal device having a conversion table for storing the relationship, and when transmitting character information to the terminal device, the character information and the font data corresponding to the character code are paired with respect to the character information to be transmitted. It is characterized by transmitting to.

  Also, the font data specified by the received data when receiving the data for specifying the font to be used from the terminal device, specifying the font data to be used by the received data, and transmitting the character information to the terminal device Is preferably used.

  In addition, a user information storage unit that stores the identification information of the user and the font used by the user in association with each other is received, and the user identification information is received from the terminal device as data for specifying the used font. It is preferable that the corresponding used font is read from the user information storage unit and specified based on the user identification information.

  In addition, the present invention is a terminal device that receives an information providing service from a communication network, and receives character information as a pair of font data including a character code and a dot map corresponding to the character code. Corresponding characters are created and displayed based on font data.

  The terminal device is preferably a mobile phone terminal device, and the communication network is preferably the Internet connected via a public telephone line.

  As described above, according to the present invention, font data including a character code and a dot map corresponding to the character code is transmitted as a pair. Therefore, the terminal device that has received the information can display the character code in any language. Therefore, the terminal device can display the language of each country without storing the font data of each country.

  The font data is data for each character, and can be recognized as a display for each character when displayed on the terminal device. Therefore, editing for each character is possible in the terminal device.

  For example, even if mobile phone terminal devices in countries around the world have a common specification, a desired language can be displayed on each terminal device by holding and transmitting font data on the server side.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a diagram showing the overall configuration of the system. The mobile phone terminal device (terminal device) 10 is a normal cellular phone, and performs wireless communication with a responsible radio base station. The wireless base station is connected to the telephone station by wire and connected to the Internet through a provider. That is, in this example, the communication network is composed of a public telephone line and the Internet. It should be noted that other formats such as PHS or those using satellite communication may be used.

  The cellular phone terminal device 10 has minimum font data necessary for general communication, and can be displayed. It has a font table for ASCII codes, but does not have font tables for other languages.

  The mobile phone terminal device 10 stores a general-purpose display program 10a. The general-purpose display program 10a is a program for displaying character information of this embodiment described later when it is received. The general-purpose display program 10a may be provided in advance in the mobile phone terminal device 10, but is preferably downloaded from a server on the Internet (for example, the font server 20).

  Although not shown, the mobile phone terminal device 10 includes a keypad, a handset, a communication device, a display device, a control microcomputer, and the like, as in a normal case.

  A font server 20 is provided on the Internet. The font server 20 includes a user information table 20a for storing the relationship between user identification information and the fonts used, and a character code / font for storing font codes that are character codes of each language and dot data corresponding to the character codes. It has a conversion table 20b.

  An information providing server 30 is also provided on the Internet. The information providing server 30 is provided with an e-mail service unit 30a and a content data service unit 30b. The e-mail service unit 30a manages e-mail for each address, performs e-mail transmission / reception processing in response to the user's request, and the content data service unit 30b receives the content data in response to the user's request. provide. Note that the information providing server 30 is provided on the Internet, and each mobile phone terminal device 10 can directly access the information providing server 30. Also, the electronic mail service unit 30a and the content data service unit 30b may be provided in another server, or the information providing server 30 and the font server 20 may be formed as one server. Generally, the font server 20 can access any server on the Internet.

  In such a system, when the general-purpose display program 10a does not exist in the mobile phone terminal device 10, the font server 20 that provides it is accessed, downloaded from here, and installed. Downloading and installing the program is the same as the current service and there is no problem. For example, Java is used as the program language of the general-purpose display program 10a, but is not limited thereto.

  The user connects to the font server 20 by the mobile phone terminal device 10 and transmits user identification information. This user identification information includes, for example, a user code and a password registered in advance. The font server 20 searches the user information table 20a, checks whether the user of the transmitted user identification information is registered, and if registered, stores the font used by the user. Confirm from. If the user is not registered, the user is registered first. Further, when accessed, the font used at that time may be input every time.

  Then, the user accesses various information providing servers 30 via the font server 20 and acquires information.

  Here, the font server 20 is information obtained from the information providing server 30, and if the information supplied to the mobile phone terminal device 10 includes a character code other than alphanumeric characters (alphabetic characters, Arabic numerals), The data is converted by the character code / font conversion table 20b, and the converted data is sent to the mobile phone terminal device 10.

  Here, the data to be sent to the cellular phone terminal device 10 is as shown in FIG. 2, following the header portion indicating general data such as data indicating the start of character data or data length, A code and font data of the character code are sequentially stored. One data corresponds to one line of display. In addition, the character codes may be arranged first, followed by the font data, and the data length may be fixed or variable.

  Next, font data will be described with reference to FIG. This font data is data for each dot, and is represented by white dots and black dots, for example, as shown in FIG. In this case, 7 × 7 represents one character. In this example, capital letter A is shown, but this is for simplicity, and what is actually used is a non-alphabetic character such as Japanese Kanji.

  In this example, a black dot is a dot representing a character and is processed for each line constituting the character. The first line consists of three white dots, black dots, and three white dots. The second and third lines consist of two white dots, black dots, white dots, black dots, and two white dots. The fourth line is composed of white dots, black dots, three white dots, black dots, white dots, and the fifth line is composed of white dots, five black dots, white dots, lines 6 and 7 The eyes are composed of black dots, five white dots, and black dots.

  These pieces of information are processed into English letters and numbers by mathematical compression theory to create one-character font data.

  The character code / font conversion table 20b of the font server 20 is provided with various fonts in addition to Japanese fonts, such as Korean, Chinese, German, etc., depending on the font specified by the user. Select. When the information providing server 30 supplies the character code instead of the user's selection, if the character code is to send data indicating which language font is used, it is used. Similarly, the data may be converted and transmitted to the mobile phone terminal device 10.

  In the cellular phone terminal device 10, when the received data including the above-described font data is received and the data is specified from the header, the display data shown in FIG. 3 is restored using the general-purpose display program 10a. Show on the display. Therefore, even if font data of the language is not stored in the mobile phone terminal device 10, characters of the language can be displayed.

  Therefore, even if the foreign mobile phone terminal device 10 itself is common throughout the world, any language can be displayed in any country.

  According to this method, it is possible to compress the data amount rather than simply displaying the entire screen. Since the cellular phone terminal device 10 performs display for each character, processing such as enlargement, reduction, movement, copying, and color change for each character can be performed. For example, if a black dot is changed to red, it can be changed to a red character display.

  In this way, the general-purpose display program 10a receives the character code and font data from the font server 20 and displays them on the screen based on the font data, so that the actually displayed characters are Japanese, Korean or other countries. There is no need to distinguish between different languages.

  There is already a device that can display languages of other countries on a personal computer, etc., but this is a method of storing fonts of the language to be used and displaying characters with the font information, and a large capacity storage unit This is a system that can be used on the premise of having the system, and cannot be used for a mobile phone terminal device or the like.

  Furthermore, as long as the font data exists in the font server 20, any cellular phone terminal device 10 can display the language of each country without limitation even if the user changes.

  As a result, with regard to character display, it is possible to use terminal devices with the same specifications for languages all over the world. On the other hand, it will be possible to display Japanese on mobile phones used around the world.

Here, the mobile phone terminal device 10 of the present embodiment needs to satisfy the following specifications.
(I) It is possible to access the Internet network and freely capture data.
(Ii) It has a graphic display screen and a function for displaying the captured character font data.
(Iii) Having a program (general-purpose display program 10a) necessary for these functions.

  As described above, whether or not the general-purpose display program 10a is incorporated from the outside is not particularly limited, and the program itself does not depend on the program language.

It is a figure which shows the whole structure of a system. It is a figure which shows the structure of transmission data. It is a figure explaining font data.
