Problems solved by technology

However, due to the influence of noise, external light and other factors when collecting the phase data of the pixels, the output of the phase detection data is unstable, which leads to the instability of the defocus (out of focus) position calculated based on the phase detection data, resulting in out of focus
When the recorded video is out of focus, you can only wait for the next trigger to focus, resulting in slow focus speed and poor video image quality

Abstract

The embodiment of the present invention discloses a focusing method, device, and mobile terminal, wherein the method includes: acquiring image parameters of video images collected by the mobile terminal, the image parameters including at least one of phase difference and focus value; judging Whether the image parameter satisfies a preset focus adjustment condition; when the image parameter meets the focus adjustment condition, moving the lens of the mobile terminal to a far-focus position, so as to perform image acquisition based on the far-focus position. By implementing the embodiment of the present invention, the focusing speed can be improved, and the video image quality can be improved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a focusing method, device and mobile terminal. Background technique [0002] With the continuous development of terminal technology and image processing technology, the camera function of terminals such as mobile phones is used more and more frequently, which brings convenience to users to record their lives. At present, there are many focusing methods for mobile phones, such as phase detection auto focus (PDAF for short). To determine the offset value of the focus, so as to achieve accurate focus, the phase focus is fast, so it is widely used. [0003] When recording video, the frequency of focusing is generally low to ensure user experience. However, due to the influence of factors such as noise and external light when collecting the phase data of the pixels, the output of the phase detection data is unstable, which leads to the instability of the defocus (out ...
