The audio processing unit 15 and the video processing unit 16 are controlled to decompress, and to compress the video data captured by the camera 12 and the audio data input through the audio input / output unit 18 for transmission to the counterpart terminal. To control.

The audio processor 15 compresses the voice data of the user provided from the audio input / output unit 18 and provides the compressed voice data to the transmitter / receiver 11 to transmit to the counterpart terminal through a communication network. The compressed voice data of the counterpart terminal user received through the receiver 11 is decompressed and output to the audio input / output unit 18. In this case, the audio input / output unit 18 may be a microphone and a speaker.

After the video connection unit 16 makes a call connection with the opposite terminal, the video data of the user captured by the camera 12 is compressed and provided to the transmitting / receiving unit 11 to be transmitted to the opposite terminal through a communication network. / The compressed video data for the counterpart terminal user received by the receiver 11 is decompressed and output to the display unit 17.

Here, the image data can be compressed and decompressed using MPEG-1 / 2, MPEG-4, or the like. Since the image data is well known and used, a detailed description thereof will be omitted.

When the call connection for the video communication is made as described above, the control unit 21 extracts the caller indication data from the call setting information received for the call connection and searches the address book stored in the storage unit 14 to display the caller's telephone number. It is determined whether it is stored in the address book of the user terminal.

As a result of the determination, if it is stored in the address book, the controller 21 controls the address book image control means 20 to decompress through the video processor 16 to capture a still image from the video data displayed in real time or for a predetermined time. Acquires and stores the moving picture data, and converts the still image and the moving picture data into the address book image type to automatically update the pre-stored address book image.

2 is a flowchart illustrating a method of updating an address book image according to an exemplary embodiment of the present invention, and a method of updating an address book image using the terminal described above with reference to FIG. 1 will be described in detail.

1 and 2, when a user accepts the start of a video call by pressing any key of the key input unit 13 (S11), the transmission / reception unit 11 receives the transmitted image data (S12).

The received image data is divided into audio data and video data, and decoded and decompressed by using the audio processor 15 and the video processor 16, respectively (S13).

The decoded voice data is output to the audio input / output unit 18 via the D / A converter, and the decoded video data is displayed on the display unit 17 to start a video call (S14).

Thereafter, it is determined whether a video call end command is input (S15), and when the end command is input, the video call ends (S16).

At this time, the caller indication data is extracted from the call setting information received for the start of the video call under the control of the address book image control means 20, and the received phone number of the other party is stored (S21), and the address book information corresponding to the phone number. The address book of the terminal is searched whether is present in the storage unit 14 (S22).

Thereafter, an image for updating an address book image is obtained from real-time output video data (S23), and the image previously stored in the searched address book is automatically updated with the obtained image (S24).

If there is no searched address book information, the user may select whether to generate address information including the obtained image and store it in the address book.

For example, a single still image is captured from the video data displayed in real time during a video call and stored in the storage unit 14, and the pre-stored address book image is automatically updated with the captured still image, or the video for a predetermined time. By storing the data, the previously stored address book image may be automatically updated with the video data.

Also, for capturing the still image, for example, when the other party's face screen is over a certain ratio of the entire screen or by using a face recognition technology after a predetermined time for capturing the still image from the video data after the video call connection is stabilized. If the face is in the middle of the screen, it is captured and stored in the storage unit 14 and automatically updates the image of the retrieved address book information with the captured still image.

In this case, when the pre-stored address book image exists, the still image or video data obtained may be stored as the address book image only without updating the address book image automatically. The character of the caller displayed on the display unit 17 such as an avatar and an emoticon can be updated with an address book image.

As another example, when a user inputs an arbitrary key during a video call, the video data displayed on the screen at the time of the key input is captured as a still image to automatically update the address book image, or from the time the key is input. The address book image can be automatically updated by storing video data up to the point where the next key is input.

As another example, in the process of playing the video data received by the Multimedia Messaging Service (MMS), the image data is automatically updated by acquiring an image and updating the address book image as described above, or stored according to a user's key input. Can automatically update the address book image.

As another example, the video data of the other party displayed during the video call is captured and stored as a still image at predetermined time intervals, and after the call is finished, the captured still image is displayed to the user so that the address book image can be selectively updated. If a plurality of address book images can be stored, the captured still image can be stored without deleting the previously stored address book image so that the representative address book image can be selectively changed.

As described above, the present invention has the advantage of automatically updating the address book image by capturing the video data displayed in real time during a video call as a still image or by storing the video data at a predetermined time, thereby improving the user's convenience for address book management. have.

In addition, the automatically updated address book image is displayed on the screen together with the caller's telephone number when a call request is received from the terminal.
