Problems solved by technology

[0004] However, at present, because the pixels of the phase difference detection component (that is, the pixel of the phase PD) will be affected by various factors such as noise and external light instability, the defocus value (defocus amount) calculated by the phase difference detection component will fluctuate greatly. The motor will also oscillate back and forth, causing obvious jitter in the picture

Abstract

The invention discloses a camera focusing method and device, and a terminal. The method comprises the steps of obtaining a defocus value for a current frame detected by a phase difference detection component when it is detected that a camera is used for photographing; judging whether the defocus value for the current frame is an abnormal value or not; controlling a photosensitive element to move according to the defocus value for the current frame if the defocus value for the current frame is the abnormal value, thereby enabling the defocus value for the current frame to be in a normal range. Through movement control of the photosensitive element, the defocus value detected by the phase difference detection component will not be changed suddenly, the defocus value calculated by the phase difference detection component can be prevented from being excessively oscillatory and unstable, and the use experience of a user is improved.

Description

technical field [0001] The present invention relates to the technical field of terminals, in particular to a camera focusing method, device and terminal. Background technique [0002] In the process of shooting with a smart terminal, a user often needs to focus. Focusing is the process of changing the object distance and distance position through the intelligent terminal focusing system, so that the object to be photographed is imaged and cleaned. At present, there are many focusing technologies, such as phase focusing technology, contrast focusing technology and laser focusing technology. Among them, the phase focusing technology is favored by more and more users because of its fast focusing speed. [0003] In phase focusing technology, the phase difference detection component is composed of left and right pixel points in pairs. The smart terminal acquires the first image through the left pixel and the second image through the right pixel, and then generates the image da...
