  • Patent number: 7639266
    Abstract: A transmission-side cellular phone sends, via a mail server, to a reception-side cellular phone a face image and its attribute information as an attachment to an email. The reception-side cellular phone extracts the face image from the email, selects face part images from among a plurality of face part images stored in the face part storing section, combines the face image and the selected face parts, and displays the combined image. The reception-side cellular phone selects the face part images based on, for example, a number of times a telephone call from a person was not attended in a predetermined period.
