Problems solved by technology

[0004] However, in practical applications, if omnidirectional recording is adopted, not only the sound of the video subject, but also sounds from all other angles can be obtained, which makes the background noise in the recording result too large, which seriously affects the recording quality

Embodiment Construction

[0053] The following will clearly describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative efforts belong to the protection scope of the present invention.

[0054] The term "face recognition" refers to a biometric technology for identification based on human facial feature information. Use a camera or camera to collect images or video streams containing faces, and automatically detect and track faces in the images, and then perform a series of face processing and recognition related technologies on the detected faces, usually also called portrait recognition ,face recognition.

Abstract

The embodiment of the invention discloses a method for recording the sound of a video recording object and a mobile terminal, which are used to reduce the background noise in the recorded sound of the recording object and improve the recording quality. The method in the embodiment of the present invention includes: the mobile terminal obtains the location information of the recording object through face recognition, converts the location information into beam configuration information as an input parameter of the beamforming technology, and performs beamforming processing on the recorded sound signal , so that the signal strength of the sound signal at the location of the recording object is enhanced, and the signal strength of the sound signals at other directions is attenuated, so that the sound at the location of the recording object is obtained.

Description

technical field [0001] The invention relates to the field of data processing, in particular to a method and a mobile terminal for recording the sound of a recording object. Background technique [0002] Video recording refers to the recording of images by optical, electromagnetic and other methods, such as recording a child's movement, or an animal's foraging process, etc. With the development of electronic technology, recordings are generally also made at the same time during the video recording process. Get complete audio and video information. [0003] At present, because the position of the recorded object will change dynamically during the recording process, in order to collect the sound of the recorded object, omnidirectional recording is generally used in the recording process, that is, the sound enters the microphone from 0 to 360 degrees and the output will not be obvious. The change. [0004] However, in practical applications, if omni-directional recording is ad...
