Method and apparatus for operating notification function in user device

1. A method for operating a notification function in a user device, the notification function being configured to notify to the user as a notification mode of an occurrence of a notification event, the method comprising:

detecting whether the notification event is a reception notification event or a function notification event;

detecting a face of a user by separating the face area of the user and a background area from each of images collected through a camera and executing an eye pattern from the face area of the user, when the reception or function notification event is detected;

executing the notification function to either one of a silent mode or a vibration mode from a sound notification mode in response to the detected function notification event, or outputting contents of a message simultaneously with message originator information on a display unit in response to the detected reception notification event, when the face of the user is detected in the images collected through the camera; and

preventing the notification function from changing to the silent mode by an input of the user when the face of the user is not detected in the images collected through the camera.

2. The method of claim 1 , wherein, when the notification event is not detected, the notification function is executed in the preset notification mode.

3. The method of claim 1 , further comprising:

when the reception notification event is detected,

outputting originator information and contents of a message on a display unit, when the face of the user is detected; and

outputting the reception notification information on the display unit, when the face of the user is not detected.

4. The method of claim 1 , wherein, when the face of the user is detected, the detection of the face of the user is determined when a feature point of the face of the user detected through the camera is compared with a feature point of a pre-stored face and it is determined that the feature point of the face of the user is similar to the feature point of the pre-stored face.

5. The method of claim 1 , further comprising:

executing an application supporting the notification function before the notification event is detected;

wherein a mode of the notification function is changed to one of a silent mode and a vibration mode when the face of the user is detected, and

wherein the notification function is executed in a preset notification mode when the face of the user is not detected.

6. A user device for operating a notification function, the notification function being configured to notify to the user as a notification mode an occurrence of a notification event, the user device comprising:

a wireless communication unit configured to transmit/receive one of a call and particular data;

a camera configured to collect images;

an audio processing unit configured to output a reception sound; and

a control unit configured to:

detect whether the notification event is a reception notification event or a function notification event,

execute the notification function of notifying a user of reception of one of the call and the particular data in either of a silent mode and a vibration mode from a sound notification mode, if a face of the user is detected in response to the detected function notification event by separating the face area of the user and a background area from each of images collected through the camera,

execute an eye pattern form the face area of the user, when the reception notification event or the function notification event is detected or output contents of a messaged simultaneously with message originator information on a display unit in response to the detected reception notification event, and

prevent the notification function from changing to the silent mode by an input of the user when the face of the user is not detected in the images collected through the camera.

7. The user device of claim 6 , wherein the control unit is further configured to perform a control operation to execute the notification function in the preset notification mode, when the notification event is not detected.

8. The user device of claim 6 , wherein, when the reception notification event is detected, the control unit is further configured to perform a control operation to output the reception notification information on the display unit when the face of the user is not detected.

9. The user device of claim 6 , wherein the control unit is further configured to determine the detection of the face of the user when a feature point of the face of the user detected through the camera is compared with a feature point of a pre-stored face and it is determined that the feature point of the face of the user is similar to the feature point of the pre-stored face.

10. The user device of claim 6 , wherein an application supporting the notification function is further executed before the notification event is detected.
