Under the mode of the imaged viewing angle of automatic adjustment camera, main performing step is as follows:
A) camera rises to television set top, and camera is started working.
B) MIC array starts to catch sound, and camera lens starts to catch image.
Camera gets audio, video data by microphone array and camera lens, to ensure successfully to realize video calling.
C) audio frequency and video processing unit is by auditory localization technology, judges the general location of sound source.
When starting dynamic tracing function, when target (user) moves and causes sound source position to change, camera calculates the time delay that sound source (targeted voice signal) arrives each microphone, judges the general location of sound source, thus determines the position, direction of target.
D) audio frequency and video processing unit drives horizontal motor (and/or motor vertical), makes cam lens towards Sounnd source direction.
E) audio frequency and video processing unit is according to Face detection technology, determines the position of face.
The image of target on camera collection Sounnd source direction, adopts Moving Target Tracking Algorithm and Face datection algorithm to confirm the position of target cranial (being mainly people face), accurately to locate target.
F) audio frequency and video processing unit drives horizontal motor, finely tunes, make face in the center of image pickup scope to camera direction.
By above-mentioned steps A) to F) achieve the camera angle automatically adjusting camera.
