Abstract

A speaker displaying method displaying who is a speaker while many users are performing a videophone call and a videophone terminal implementing the same are provided. The method includes detecting voice characteristic information of other characters when a videophone call starts so as to match the characteristic information with character images of a received image in a one-to-one correspondence, detecting voice characteristic information from a voice received after the matching, and displaying a character image matching the detected voice characteristic information distinguished from other character images.

Claims

1. A speaker display method of a videophone terminal, the method comprising:

detecting voice characteristic information of other characters when a videophone call starts so as to match the characteristic information with character images of a received image in a one-to-one correspondence;

detecting voice characteristic information from a voice received after the matching; and

displaying a character image matching the detected voice characteristic information distinguished from other character images.

2. The method of claim 1, wherein the matching of the characteristic information comprises:

detecting voice characteristic information and character images from the received voice and image, respectively;

selecting one of the detected character images;

detecting character characteristic information of the selected character image; and

matching the detected voice characteristic information with the detected character characteristic information.

3. The method of claim 2, wherein the selecting of the detected character image comprises:

detecting a certain gesture from the received image; and

selecting one of the detected character images based on the detected certain gesture.

4. The method of claim 2, wherein the selecting of the detected character image comprises:

receiving user input information; and

selecting one of the detected character images based on the received user input information.

5. The method of claim 2, wherein the matching of the detected voice characteristic information comprises:

masking and displaying an unregistered character image of the detected character images,

wherein the unregistered character image is an image not matching the voice characteristic information.

6. The method of claim 2, wherein the detected voice character information and the character characteristic information are tone information and location information, respectively.

7. The method of claim 1, wherein the displaying of the character image comprises displaying a contour of a character image matching with the detected voice characteristic information.

8. A videophone terminal comprising:

a radio frequency communication unit for receiving an image and a voice;

a controller detecting voice characteristic information from the received voice, for detecting character characteristic information of character images from the received image, for matching the detected voice characteristic information with one of the detected character characteristic information, and for determining a corresponding character image of the matched character characteristic information as a speaker image of the received voice;

a memory for storing the detected voice characteristic information and character characteristic information matching the detected voice characteristic information; and

a display unit for displaying the determined speaker image distinguished from other character images.

9. The videophone terminal of claim 8, wherein the controller comprises:

a detecting unit for detecting the voice characteristic information from the received voice and for detecting a certain gesture and the character characteristic information of character images from the received image;

a speaker determining unit for matching one of the detected character characteristic information with the detected voice characteristic information based on the detected certain gesture so as to determine the speaker image of the received voice; and

an image processing unit for processing the received image to distinguish the determined speaker image from other character images, and for outputting the processed image on the display unit.

10. The videophone terminal of claim 9, wherein:

the speaker determining unit searches character characteristic information matching the detected voice characteristic information from the memory so as to determine a character image corresponding to the searched character characteristic information as the speaker image, and

the speaker determining unit selects one of the detected character characteristic information based on the detected certain gesture when the character characteristic information matching the detected voice characteristic information is not found in the memory so as to match the selected character characteristic information with the detected voice characteristic information.

11. The videophone terminal of claim 10, wherein the speaker determining unit controls the image processing unit to mark an unregistered character image when the character characteristic information matching the detected voice characteristic information is not found in the memory,

wherein the unregistered character image is an image in which character characteristic information is not stored in the memory.

12. The videophone terminal of claim 11, wherein the speaker determining unit receives user input information from a touch screen and selects one of the detected character characteristic information based on the received user input information.

13. The videophone terminal of claim 8, wherein the display unit displays a contour of the determined speaker image.

14. The videophone terminal of claim 8, wherein the controller detects tone information from the received voice and detects location information of a character image from the received image.

15. The videophone terminal of claim 9, wherein the controller comprises:

a detecting unit for detecting the voice character information from the received voice and for detecting a certain gesture and the character characteristic information of character images from the received image;

a speaker determining unit for receiving user input information from a touch screen and for matching one of the detected character characteristic information with the detected voice characteristic information based on the received user input information to determine a speaker image; and

an image processing unit for processing the received image to distinguish the determined speaker image from other character images, and for outputting the processed image on the display unit.

16. A videophone terminal, comprising:

a communication unit for receiving data associated with a videophone call;

a display unit for displaying at least one character image, each character image corresponding to a speaker in the videophone call, the display unit including a touch screen for receiving a user input;

a controller for detecting voice characteristic information from a received voice, for detecting character characteristic information corresponding to each of the at least one character image, for matching the voice characteristic information with character characteristic information corresponding to one of the at least one character image, and for determining the corresponding character image as a speaker image of the received voice; and

a memory for storing the voice characteristic information and the character characteristic information matching the voice characteristic information,

wherein the controller controls the display unit to display the character image corresponding to the speaker image differently than the other character images.

17. The videophone terminal of claim 16, wherein, in response to the user input, the controller controls the display unit to display a divided screen including a main screen and a sub screen, controls the display unit to display the at least one character image in the main screen, and controls the display unit to display at least one application icon in the sub screen.

18. The videophone terminal of claim 17, wherein, in response to the user input corresponding to one of the at least one application icon, the controller controls the display unit to display information corresponding to the at least one application icon and the speaker image.
