Abstract

The embodiment of the invention relates to the field of electronic technology, and discloses a contrast focusing method and a mobile terminal. Wherein, the method includes: when receiving a focus instruction for the target object, the mobile terminal will obtain the phase difference value between the two image data waveforms for the target object, and judge whether the phase difference value satisfies the contrast formula If the starting condition of the focus mode is satisfied, the contrast focus mode is started, and the focus data of the focus position of the camera is determined according to the phase difference value in the contrast focus mode, and finally the lens of the camera is controlled to move to the focus position according to the focus data. focus position. Through the embodiment of the present invention, when the contrast focus mode is started, the direction of the focus position of the camera can be determined by the obtained phase difference value, and then the lens of the camera is directly controlled to move in this direction, so that the focus position can be quickly found and the focus can be improved. The focusing speed of contrast focusing improves user experience.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a contrast focusing method and a mobile terminal. Background technique [0002] Current mobile terminals such as smartphones, tablet computers, notebook computers, etc. will focus before using the camera to take pictures. Focusing methods in the prior art include phase focusing, contrast focusing, and laser focusing. [0003] In the existing contrast focusing technology, the mobile terminal needs to move the lens of the camera according to a preset track to find the best focus position of the camera. It can be seen that the focusing speed of this focusing method is relatively slow. Contents of the invention [0004] The embodiment of the present invention discloses a contrast focusing method and a mobile terminal, which can quickly find the best focusing position for a camera lens, thereby improving the focusing speed of the contrast focusing. [0005] The embodiment of ...
