Problems solved by technology

Among these methods, laser focusing requires the object to be photographed to have a high reflectivity to the laser, and when shooting without a picture has a low reflectivity to the laser, the autofocus effect is poor; dual-camera focus, phase focus and contrast focus require The ambient light is bright, so that the scanned object pattern can be accurately auto-focused, and in the case of low ambient light, the scanned object pattern is not clear enough, and the auto-focus effect is poor

Abstract

The invention relates to an automatic focusing method. The method comprises the following steps: controlling a first driving module to drive a first image acquisition module to perform automatic focusing on a target object through a preset mode; acquiring a first driving quantity of the first driving module to the first image acquisition module; querying a second driving amount associated with the first driving amount according to a preset association relationship; and controlling the second driving module to drive the second image acquisition module to perform automatic focusing on the target object according to the second driving amount. According to the embodiment of the invention, compared with automatic focusing modes such as contrast focusing, phase focusing and double-shooting focusing in the related technology, automatic focusing can be accurately carried out under the condition that ambient light is dark, and compared with an automatic focusing mode of laser focusing in the related technology, the method can be applied to accurate automatic focusing of more types of objects.

Description

technical field [0001] The present disclosure relates to the technical field of image acquisition, and in particular to an autofocus method, an autofocus device, electronic equipment, and a computer-readable storage medium. Background technique [0002] In the related art, in order to simplify the user's shooting operation on the object, the terminal with the image acquisition function provides an auto focus (also called auxiliary focus) function, which can automatically complete the focal length adjustment of the image acquisition module when the user shoots the object. adjustment, eliminating the need for the user to manually adjust the focus. [0003] Auto focus mainly includes dual camera focus, phase focus, contrast focus, laser focus and other methods. Among these methods, laser focusing requires the object to be photographed to have a high reflectivity to the laser, and when shooting without a picture has a low reflectivity to the laser, the autofocus effect is poor;...
