WIPO Patent Application WO/2021/022810
Kind Code:
A1
Abstract:
Provided are an automatic focusing method and apparatus, an electronic device, and a readable storage medium. According to the method, by means of acquiring the frames per second of a currently played video stream, acquiring gap time intervals between frames on the basis of the frames per second, wherein there are two or more gap time intervals, then inserting a focusing image into each gap time interval, and recording the stroke position of a focusing motor of an electronic device each time the focusing image is inserted, then calculating the definition of each focusing image, finding the focusing image with the highest definition, and moving the motor to the stroke position corresponding to the focusing image, focusing can be completed. By using the method to perform automatic focusing, interruption, due to the fact that focusing is to be performed, of a video stream that is being played can be avoided, thereby improving the viewing experience of a user.
