Problems solved by technology

However, these focusing methods used by the auxiliary camera also have some disadvantages. For example, CDAF has a serious blowing phenomenon, and the focusing time is long, and the shooting picture is blurred during the focusing process; similarly, the laser focusing process takes a long time. And the shooting picture is blurred during the focusing process, which affects the user experience

Abstract

The invention provides a focusing method and electronic equipment. The electronic equipment comprises a processor and at least two cameras, wherein a first camera in the at least two cameras is used for detecting phase information of an image; a second camera of the at least two cameras is used for detecting contrast information of the image; the processor is used for determining at least one phase focusing position of the second camera according to one or more phase focusing positions of the first camera in the phase detection and automatic focusing process of the first camera, and controlling the second camera to move to the at least one phase focusing position; and determining a contrast focusing position of the second camera according to contrast information of an image detected by thesecond camera at one or more phase focusing positions in the at least one phase focusing position, the contrast focusing position of the second camera comprising a contrast focusing movement direction of the second camera. According to the embodiment of the invention, rapid focusing can be realized.

Description

technical field [0001] The present application relates to the field of electronic equipment, and more specifically, to a focusing method and electronic equipment. Background technique [0002] With the development of science and technology, more and more electronic devices support dual cameras or multiple cameras in order to meet users' diverse needs for shooting. For example, existing smart phones generally have rear dual cameras or front dual cameras. [0003] Based on cost considerations in existing electronic devices with dual cameras, usually only one camera (the camera may be called a main camera, and the other camera may be called an auxiliary camera) supports phase detection autofocus (PDAF). [0004] When shooting, a focusing method of the existing electronic equipment is as follows: the main camera first uses PDAF to determine the quasi-focus position of the main camera, and after the main camera focuses, the auxiliary camera determines and adjusts the quasi-focus ...
