In a specific implementation, the second determining unit 601 may determine whether the distances between at least one person and the mobile terminal are all greater than a second preset distance, where the detecting unit 402 may detect more than one person during the rotation of the rotating camera of the mobile terminal, at this time, the determining unit 403 may determine the shortest distances between the persons and the mobile terminal, and the second determining unit 601 determines whether the shortest distance is greater than the second preset distance, which may be set by the user, and specifically, the second preset distance may include but is not limited to: 10 meters, 15 meters, 20 meters, 20.5 meters, etc., the second set distance may also be defaulted by the system, and 10 meters may be defaulted to the second preset distance.
A holding unit 602, configured to hold the volume of the speaker if the second determining unit 601 determines that the distances between the at least one person and the mobile terminal are all greater than a second preset distance.
In a specific implementation, if the second determining unit 601 determines that the distance between at least one person and the mobile terminal is greater than the second preset distance, that is, in a case that the rotating camera of the mobile terminal detects one person, the second determining unit 601 may determine the distance between the person and the mobile terminal, and if the distance is greater than the second preset distance, the speaker of the mobile terminal is maintained; in case that 2 or more than 2 persons are detected by the rotary camera of the mobile terminal, the mobile terminal may determine the shortest distance between the persons and the mobile terminal, and maintain the speaker of the mobile terminal in case that the shortest distance is greater than a second preset distance.
In the answering process by using the loudspeaker of the mobile terminal, the control unit 401 controls the rotary camera of the mobile terminal to rotate; in the process of rotating the rotary camera, the detection unit 402 detects a person in a shot picture of the rotary camera; in a case where the detection unit 402 detects at least one person, the determination unit 403 determines a distance between the at least one person and the mobile terminal; the adjusting unit 404 adjusts the volume of the speaker according to the distance between the at least one person and the mobile terminal determined by the determining unit; the second determining unit 601 determines whether the distances between the at least one person and the mobile terminal are all greater than a second preset distance; if the second determining unit 601 determines that the distances between the at least one person and the mobile terminal are all greater than a second preset distance, the holding unit 602 holds the volume of the speaker. By adopting the embodiment of the invention, when the user starts the loudspeaker to answer, the distance between the person in the picture shot by the rotary camera and the mobile terminal is determined by the rotary camera, the volume of the loudspeaker is adjusted according to the distance, and the loudspeaker is closed when the distance between the person and the mobile terminal is detected to be smaller than the first preset distance, so that the influence of too large volume of the loudspeaker on other people is greatly avoided.
