Abstract

Method and apparatus for switching talking mode automatically applicable to electronic equipment, which includes an accelerometer, proximity sensor and video camera. The method includes acquiring gravity information from the accelerometer during conversation between the electronic equipment and the other side of the conversation, and judging whether the electronic equipment is in a vertical state according to the gravity information; activating the video camera to take a capturing action if the electronic equipment is not in a vertical state, and acquiring distance information and/or image information, the distance information used for indicating distance to the captured object, and the image information used for indicating the captured object; and switching the talking mode to speakerphone mode if distance indicated by the distance information is greater than a first threshold value, and/or resolution of the image indicated by the image information is greater than a second threshold value.

Claims (30)

1. A method for switching talking mode automatically, the method being applicable to electronic equipment, the electronic equipment comprising an accelerometer, a proximity sensor and a video camera, wherein the method comprising:

acquiring gravity information from the accelerometer during conversation between the electronic equipment and the other side of the conversation, and judging whether the electronic equipment is in a vertical state according to the gravity information;

activating the video camera to take a capturing action if the electronic equipment is not in a vertical state, and acquiring distance information and/or image information, the distance information being used for indicating the distance from the video camera to the captured object, and the image information being used for indicating the captured object; and

switching the talking mode of the electronic equipment to a speakerphone mode if the distance indicated by the distance information is greater than a first threshold value, and/or the resolution of the image indicated by the image information is greater than a second threshold value.

2. The method according to claim 1 , further comprising

acquiring detection information from the proximity sensor if the electronic equipment is in a vertical state, the detection information being used for indicating whether there is an object close to the electronic equipment; and

switching the talking mode of the electronic equipment to a receiver mode if it is determined according to the detection information that there is an object close to the electronic equipment.

3. The method according to claim 2 , wherein before acquiring detection information from the proximity sensor, the method further comprises:

activating the proximity sensor to detect whether there is an object close to the electronic equipment.

4. The method according to claim 1 , wherein before acquiring gravity information from the accelerometer, the method further comprises:

activating the accelerometer to detect the gravity of the electronic equipment.

5. An apparatus for switching talking mode automatically, the apparatus being contained in an electronic equipment, the electronic equipment further comprising an accelerometer, a proximity sensor and a video camera, wherein the apparatus comprises:

a first acquiring unit configured to acquire gravity information from the accelerometer during a conversation between the electronic equipment and the other side of the conversation;

a first judging unit configured to judge whether the electronic equipment is in a vertical state according to the gravity information acquired by the first acquiring unit;

a second acquiring unit configured to activate the video camera to take a capturing action when the result of judgment of the first judging unit is that the electronic equipment is not in a vertical state, and for acquiring distance information and/or image information from the video camera, the distance information being used for indicating the distance from the video camera to the captured object, and the image information being used for indicating the captured object; and

a switching unit configured to switch the talking mode of the electronic equipment to a speakerphone mode when the distance indicated by the distance information acquired by the second acquiring unit is greater than a first threshold value, and/or the resolution of the image indicated by the image information acquired by the second acquiring unit is greater than a second threshold value.

6. The apparatus according to claim 5 , wherein the apparatus further comprises:

a second judging unit configured to judge whether the distance indicated by the distance information acquired by the second acquiring unit is greater than the first threshold value, and/or whether the resolution of the image indicated by the image information acquired by the second acquiring unit is greater than the second threshold value, such that the switching unit performs the switching operation when the result of judgment of the second judging unit is positive.

7. The apparatus according to claim 5 , wherein the apparatus further comprises:

a third acquiring unit configured to acquire detection information from the proximity sensor when the result of judgment of the first judging unit is that the electronic equipment is in a vertical state, the detection information being used for indicating whether there is an object close to the electronic equipment; and

wherein the switching unit switches the talking mode of the electronic equipment to a receiver mode when it is determined according to the detection information acquired by the third acquiring unit that there is an object close to the electronic equipment.

8. The apparatus according to claim 7 , wherein the apparatus further comprises:

a second activating unit configured, before the third acquiring unit acquires the detection information from the proximity sensor, to activate the proximity sensor to detect whether there is an object close to the electronic equipment.

9. The apparatus according to claim 5 , wherein the apparatus further comprises:

a first activating unit configured, before the first acquiring unit acquires the gravity information from the accelerometer, to activate the accelerometer to detect the gravity of the electronic equipment.

10. An electronic equipment, comprising an accelerometer, a proximity sensor and a video camera, wherein the electronic equipment further comprises the apparatus for switching talking mode automatically as claimed in claim 5 .

11. An electronic equipment, comprising an accelerometer, a proximity sensor and a video camera, wherein the electronic equipment further comprises the apparatus for switching talking mode automatically as claimed in claim 6 .

12. An electronic equipment, comprising an accelerometer, a proximity sensor and a video camera, wherein the electronic equipment further comprises the apparatus for switching talking mode automatically as claimed in claim 7 .

13. An electronic equipment, comprising an accelerometer, a proximity sensor and a video camera, wherein the electronic equipment further comprises the apparatus for switching talking mode automatically as claimed in claim 8 .

14. An electronic equipment, comprising an accelerometer, a proximity sensor and a video camera, wherein the electronic equipment further comprises the apparatus for switching talking mode automatically as claimed in claim 9 .
