Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a mobile communication terminal, and more particularly, to an improvement of a mobile communication terminal such as a mobile phone that realizes a chat function using electronic mail.
[0002]
[Prior art]
Recently, most mobile phones can send and receive e-mail. Conventionally, there has been a mobile phone that realizes a pseudo chat function using the e-mail transmission / reception function of such a mobile phone (for example, Patent Document 1). Chat is a communication mode in which conversation is performed in real time between two or more communication terminals using characters.
[0003]
The e-mail addressed to the mobile phone is temporarily stored in a mail server installed in the mail center of the carrier (carrier). When the e-mail arrives, this mail server sends a mail reception notification to the destination mobile phone. The mobile phone that has received this mail reception notification immediately starts receiving e-mail from the mail center. That is, in the case of a mobile phone, if the radio wave condition is good, it is possible to receive an e-mail at a speed according to real time.
[0004]
Therefore, in the mobile phone, a near real-time chat function can be realized by using a normal e-mail transmission / reception function even if the telecommunications carrier does not provide a special service for realizing the chat function. That is, the chat function is realized in a pseudo manner only by processing inside the mobile phone.
[0005]
In a mobile phone having such a pseudo chat function, e-mail is transmitted / received to / from registered members by registering in advance the mail addresses of members participating in the chat. When an e-mail from a registered member is received while the chat screen is displayed, the body of the e-mail is displayed as a chat message in chronological order on the chat screen, and a text conversation is established between two or more members. .
[0006]
In the member registration, the name of the member corresponding to the mail address is registered together with the registration of the mail address, and the name of the registered member corresponding to the mail address of the chat message sender is displayed on the chat screen. The member name is displayed in association with the chat message. For example, the name of the sender of the chat message is displayed at the beginning of the message.
[0007]
FIG. 12 is a diagram showing an example of a chat screen display in a conventional mobile phone. Each chat message transmitted and received during the chat is displayed in the chat screen, and the corresponding member name is displayed at the beginning of the message in these chat messages. By displaying the member name in this way, it is possible to identify who the chat message is from.

[Problems to be solved by the invention]
The conventional mobile phone described above has a problem that it is difficult for the user to identify who the chat message is. That is, in a mobile phone that is required to be downsized to improve portability, the display screen is limited to a small one. For this reason, the member name displayed on the chat screen in association with the chat message is small and difficult to see. Further, since the number of characters that can be displayed in the chat screen is limited, the member name displayed on the chat screen is not a full name, but only a part of the name, for example, a surname. For this reason, when a registered member has a member with the same surname, it is difficult to identify a chat message from the member.
[0010]
The present invention has been made in view of the above circumstances, and an object thereof is to improve the convenience of a mobile communication terminal that implements a chat function using electronic mail. In particular, an object is to provide a mobile communication terminal that allows a user to easily identify who the chat message is.
[0011]
[Means for Solving the Problems]
The mobile communication terminal according to the present invention displays member chatting means for storing members who participate in chat as registered members, a chat screen, and chats with the body of an e-mail received from the registered member as a chat message while the chat screen is displayed. The chat processing means is displayed on the screen and outputs a chat message created while the chat screen is displayed to the registered member as an e-mail. The member storage means stores registered members in association with images. The chat processing means displays an image corresponding to the chat message transmission source on the chat screen in association with the chat message.
[0012]
According to such a configuration, by storing the registered member in the member storage unit in association with the image, the chat processing unit can display the image in the chat screen in association with the chat message. That is, since the registered member is stored in association with the image, the chat processing means determines the registered member who is the transmission source of the chat message, and associates the image corresponding to the chat message with the chat message on the chat screen. Can be displayed.
[0013]
In addition to the above-described configuration, the mobile communication terminal according to the present invention displays member reception means for member registration, telephone book storage means for storing an email address and an image in association with a telephone number, an incoming call screen, Incoming call processing means for reading out an image from the telephone directory storage means based on the telephone number of the caller and displaying it on the incoming call screen, wherein the member registration means assigns the mail address corresponding to the registered member in the member registration to the member storage means. Is stored in the member storage means in association with the image stored in the telephone directory storage means.
[0014]
According to such a configuration, since the mail address and the image are stored in the phone book storage unit in association with the telephone number, the member registration unit can be used as the phone book storage unit by inputting the mail address of the registered member. The e-mail address can be stored in the member storage means in association with the image stored in. That is, if an e-mail address corresponding to a registered member is input to perform member registration, an image is automatically read out from the telephone directory storage unit based on this e-mail address. Thus, the member registration unit can register the read image in the member storage unit in association with the mail address.
[0015]
In addition to the above configuration, the mobile communication terminal according to the present invention includes a character size changing unit that changes a character size of a chat message displayed on the chat screen based on a user operation input, and an image displayed on the chat screen. Image size changing means for changing the image size to an image size corresponding to the character size of the chat message.
[0016]
According to such a configuration, the image size of the image displayed on the chat screen is changed in accordance with the character size of the chat message displayed on the chat screen. Therefore, for example, when the character size is reduced, the image size can be reduced according to the character size.
[0017]
Further, in the mobile communication terminal according to the present invention, in addition to the above configuration, the chat processing means displays an image corresponding to the chat message on the left side of the chat message, and a portion of the chat message exceeding a predetermined number of lines is displayed. It is configured to be displayed under the image.
[0018]
According to such a configuration, a part of the chat message exceeding a predetermined number of lines can be displayed by being wrapped under the image. That is, the chat processing means determines the number of lines of the chat message to be displayed on the chat screen, and when the number of lines exceeds a predetermined number of lines, a part of the chat message is wrapped under the image corresponding to the chat message. Can be displayed.
[0019]
In addition to the above configuration, the mobile communication terminal according to the present invention includes character size changing means for changing the character size of the chat message displayed on the chat screen based on a user operation input, and the chat processing means includes: An image corresponding to the chat message is displayed on the left side of the chat message, and the number of lines that can be displayed in the chat message is changed according to the character size of the chat message.
[0020]
According to such a configuration, the number of lines that can be displayed in the chat message is changed in accordance with the character size of the chat message displayed on the chat screen. Therefore, for example, when the character size is reduced, the number of lines that can be displayed can be increased according to the character size.

The member registration unit 6 performs registration processing of members who participate in chat based on user operation input. Member registration is performed when the user directly inputs a mail address or when the user selects and designates a mail address ma stored in the telephone directory storage unit 8. In this way, each time a mail address corresponding to a member participating in the chat is input, the mail address is stored in the member storage unit 7.
[0030]
In addition, as the registered member's mail address is stored in the member storage unit 7, the member registration unit 6 reads the image pc and the name from the telephone directory storage unit 8. These images pc and names are read based on the mail address and stored in the member storage unit 7 as member information. In particular, the read image pc is stored as a member image mp in association with the mail address ma. That is, when a mail address is input in member registration, the member registration unit 6 searches the phone book storage unit 8 and member information corresponding to the mail address is automatically stored in the member storage unit 7 together with the mail address. The
[0031]
Here, when the image corresponding to the input mail address is not stored in the telephone directory storage unit 8, the default image stored in the default image storage unit 10 is registered in the member storage unit 7. . The default image is an image irrelevant to the registered member, and dummy image data prepared in advance is used.
[0032]
The member storage unit 7 is a storage unit that stores members participating in the chat as registered members (chat members). The member storage unit 7 stores member information, that is, a member name mp associated with the registered member name and the registered member, in addition to the mail address ma of each registered member, in association with the mail address ma. The chat processing unit 5 determines a registered member based on the mail address ma held in the member storage unit 7.

Therefore, the user himself / herself sets the phone book storage unit 8 for each member registration. There is no need to search and select images. Therefore, the trouble at the time of member registration can be saved and the convenience can be improved. In addition, since an image stored in advance in the phone book storage unit 8 for a picture call is registered as a member image, and this image is used for displaying a chat screen, a dedicated image for displaying the chat screen is newly prepared. Therefore, the configuration of the mobile phone 1 can be simplified.
[0050]
In the present embodiment, an example in which member registration is performed by directly inputting a mail address or selecting and specifying a mail address stored in the telephone directory storage unit 8 has been described. The present invention is not limited to this. For example, if a plurality of mail addresses are stored in advance as a mailing list or the like in order to send e-mails to a plurality of partners all at once, such a mail address database may be used for member registration. good. In this case, in the member registration, if the database is selected and designated by the user, a plurality of mail addresses stored in this database are registered as a member. With this configuration, members who want to participate in the chat can be registered together using an existing database.
[0051]
In batch member registration based on the above database, if there is already data such as an email address in the registered member storage unit 7, all email addresses in the database are registered as members after erasing these data. desirable. In this way, since only the mail addresses stored in the database are registered as members, it is possible to save the trouble of deleting the registration of members not stored in the database.
