Electronic device having message-recording and message-playback function and related method

1. An electronic device having message-recording and message-playback function, comprising:

an image capture unit;

a storage unit storing a plurality of facial images of members and a relationship list recording relationships between messages left by members and facial images of message recipients of the messages;

whereby the image capture unit captures the facial images of the members at predefined time intervals until the image capture unit captures at least one facial image of all members; and

a processing unit to:

a). detect whether there is an unplayed message existing in the storage unit,

b). determine the facial images of the message recipients association with the unplayed message according to the relationship list when there is an unplayed message existing in the storage unit,

c). control the image capture unit to capture facial images of members in front of the electronic device,

d). compare the facial images associated with the unplayed message with the captured facial images of members, and determine whether at least one member who has not received the unplayed message is in front of the electronic device according to the comparative result; and

e). play the unplayed message when at least one member who has not received the unplayed message is in front of the electronic device.

2. The electronic device as described in claim 1 , wherein the electronic device initiates an operation system of the electronic device before the processor detects whether there is an unplayed message existing in the storage unit.

3. The electronic device as described in claim 1 , wherein the message is audio, video or a message containing audio and images.

4. The electronic device as described in claim 3 , wherein the electronic device comprises an audio collection unit, the member leaves one or more messages via the audio collection unit.

5. The electronic device as described in claim 4 , wherein the member leaves one or more messages further via the image capture unit.

6. The electronic device as described in claim 4 , wherein the electronic device comprises a voice output unit and a display unit, the processor decodes the message into audio or image data as required, the audio date is reproduced through the voice output unit and the image data is reproduced through the display unit.

7. The electronic device as described in claim 1 , wherein the electronic device is a smart TV.

8. The electronic device as described in claim 1 , wherein the processor generates a mark to mark the message as a played message corresponding to the member after the unplayed message has been played.

9. A method for completing message-playback on an electronic device, the electronic device comprising an image capture unit, a storage unit storing a plurality of facial images of members of the electronic device and a relationship list recording relationships between messages left by members and facial images of message recipients of the messages, whereby the image capture unit captures the facial images of members at predefined time intervals until the image capture unit captures at least one facial image of all members; the method comprising:

detecting whether there is an unplayed message existing in the storage unit;

determining the facial images of the message recipients association with the unplayed message according to the relationship list when there is an unplayed message existing in the storage unit;

capturing facial images of members in front of the electronic device;

comparing the facial images associated to the unplayed message with the captured facial images of members;

determining whether at least one member who has not received the unplayed message is in front of the electronic device according to the comparative result; and

playing the unplayed message when the at least one member who has not received the unplayed message is in front of the electronic device.

10. The method described as in claim 9 , wherein the electronic device initiates an operating system of the electronic device before detecting whether there is an unplayed message existing in the storage unit.

11. The method described as in claim 9 , wherein the message is an audio, a video and a message containing audio and images.

12. The method described as in claim 11 , wherein the unplayed message is played by decoding the unplayed message into audio and image data, the audio data is reproduced through a voice output unit of the electronic device and the image data is reproduced through a display unit of the electronic device.

13. The method described as in claim 9 , wherein the method further comprises:

generating a mark to mark the message as a played message corresponding to the member after the unplayed message has been played.

14. A method for completing message-recording and message-playback on an electronic device, the electronic device comprising an audio collection unit, an image capture unit and a storage unit storing a plurality of facial images of members of the electronic device, whereby the image capture unit captures the facial images of the members at predefined time intervals until the image capture unit captures at least one facial image of all members; the method comprising:

collecting a message via the audio collection unit or/and the image capture unit in response to a input signal of a member;

determining message recipients of the collected message according to user information inputted by the member;

establishing a relationship list recording relationships between the collected message and facial images of the message recipients;

detecting whether there is an unplayed message existing in the storage unit;

determining the facial images of the message recipients association with the unplayed message according to the relationship list when there is an unplayed message existing in the storage unit;

capturing facial images of members in front of the electronic device;

comparing the facial images associated to the unplayed message with the captured facial images of members;

determining whether at least one member who has not received the unplayed message is in front of the electronic device according to the comparative result; and

playing the unplayed message when at least one member who has not received the unplayed message is in front of the electronic device.

15. The method described as in claim 14 , wherein the electronic device initiates an operation system of the electronic device before detecting whether there is an unplayed message existing in the storage unit.

16. The method described as in claim 14 , wherein the method further comprises:

generating a mark to mark the message as a played message corresponding to the member after the unplayed message has been played.
