Abstract

The invention discloses an automatic focus following method and device and a piece of user equipment; wherein the method comprises following steps of focusing according to the captured image of an object focusing area; obtaining the definition and the brightness of the image after the optimum focusing point is adjusted; photographing by taking the definition and the brightness as standard parameters; in a photographing process, detecting whether the definition and the brightness of the image change or not compared with the standard parameters; and if the definition and the brightness change, adjusting the focal length according to different change trends.

Description

technical field [0001] The invention belongs to the technical field of optoelectronics, and in particular relates to an automatic focus method and device, and user equipment. Background technique [0002] With the development of electronic technology, more and more smart devices with a camera function are used in people's lives. These smart devices with a camera function must focus on the object to be photographed to obtain a good photo quality. But none of these smart devices are equipped with a follow focus device. There are also some mechanical camera follow focus devices in the prior art, but the mechanism is relatively large and the cost is high. [0003] Therefore, how to realize the automatic focus of the smart device is a problem to be solved. Contents of the invention [0004] In view of this, the present application provides an automatic focus method and device, and user equipment, capable of realizing automatic focus on an object to be photographed by a smart ...
