In addition, the communication module 14 may provide a communication service to the user based on the contact information detected through the control unit 18. In this case, the communication service may include at least one of a voice call service, a message transmission service, and a data transmission service.

The process of detecting the contact information and providing the communication service to the user by the digital frame 10 will be described later.

The database 16 may store a number of images, each of which is mapped with contact information.

The contact information may be a mobile phone number, a landline phone number, an e-mail address, an IP address, a messenger ID, and the like, used to perform communication with respect to a subject of a corresponding image among a plurality of images. The contact information may be stored as meta information of each of the pre-stored images.

At this time, the user's digital frame 10 may be mobile communication with the other user's mobile phone through the mobile phone number, and may provide a voice call service through the VoIP network to the user through the IP address.

As shown in FIG. 6C, the database 16 includes a predetermined image T11 and meta information corresponding to the predetermined image T11 (for example, a name that is an object of the predetermined image T11). Autumn leaves), a buddy list including the number (010-000-0000), and the like.

The controller 18 detects an image selected by the user, detects an image corresponding to the detected image among the plurality of images stored in the database 16 based on the detected image, and contacts information corresponding to the detected image. Can be detected.

For example, when the user selects a point from the entire image area where the image is displayed through the display unit 20 using a touch screen, the controller 18 includes a predetermined point including the point.

For example, when the at least one subject is a restaurant, the user may order a desired food by communicating with the restaurant owner.

Meta information (FIG. 2) generated by the control unit 18 may be stored in the database 16, and the group image including the meta information may be transferred to another user (ie, another user's digital frame). It may be transmitted (S7).

When the group image TM including meta information is transmitted to another user, the other user may communicate with at least one subject (Hong Gil Dong, Kim Cheol Soo, and Lee Jung Soo) based on the meta information (S9). For example, the digital picture frame of another user may receive a group image including meta information from another digital picture frame and store it in a database.

Referring back to FIG. 1, the display unit 20 displays an image. For example, the display unit 20 may display an image received through the receiver 12, the communication module 14, the database 16, the controller 18, and / or the camera 24. In this case, the display unit 20 may be implemented as a flat panel display device such as a TFT-LCD, a PDP, or an OLED, and may be used as a touch screen.

In addition, the display unit 20 may display various graphical user interfaces (GUIs) for providing a communication service (eg, a message transmission service or a data transmission service) provided to a user.

The camera 24 may photograph the subject in response to an image photographing signal (not shown) input from the user through the key input unit 22. For example, the camera 24 may photograph the subject as a still image or a moving image, and the captured still image or the moving image may be displayed through the display unit 20.

The voice processing unit 26 may include a microphone (not shown) and a speaker (not shown).
