Abstract

The invention discloses a focusing method, device and terminal equipment, wherein the method includes: identifying a portrait area in a frame during video shooting, and determining the depth of field of the portrait area when the portrait area is identified. Determine whether to focus according to the difference in depth of field in the portrait area between different frames. Avoiding the method of detecting shaking in the prior art to trigger focusing, but using the detection of depth of field information to perform focusing. When recording a video, even if you do not focus frequently, because the depth of field of the portrait area is controlled within a certain range, you can also capture a clearer portrait image. It solves the technical problem of frequent focusing of the camera lens during the shooting process in the prior art, optimizes the shooting effect, and avoids the situation of repeated zooming of the picture in the shooting picture.

Description

Technical field [0001] The present invention relates to the field of photographing technology, in particular to a focusing method, device and terminal equipment. Background technique [0002] When a terminal device is shooting a video, it often shakes due to the movement of the body, causing the object to be photographed cannot be clearly imaged. In order to solve the problem of incapable of clear imaging in video shooting, the shaking of the screen or the body is monitored. When a large amount of shaking occurs in the shot screen or the body, after shaking stops, trigger refocusing. [0003] However, in actual use, it is found that when recording a video, the user is often in a mobile state, and even a slight jitter will trigger the auto focus. This leads to frequent lens focusing, which affects the shooting effect. In the shooting picture, the picture zooms repeatedly. Summary of the invention [0004] The purpose of the present invention is to solve one of the above technical ...
