  • Patent number: 9276891
    Abstract: The present invention aims at offering a mobile communication device allowing the user to identify the sender when the user selects or opens a mail in a mail list by outputting an image and music that have been registered to the address book. Accordingly, when a mail is selected in the mail list of the mail box 401, or when a mail is opened and the mail message is displayed, the received mail display control unit 140 searches a mail address of the sender of the received mail in the address book 301. If the image/music data ID information 303(?) that has been registered in association with the sender of the mail address is present in the address book 301, the received mail display control unit 140 reads image data or music data from the image/music information 302 of the information storage unit 100 based on the image-music data ID information 303.
