Abstract

Embodiments of the present invention provide a method and device for automatically adjusting focus, including: focusing a lens of a photographing device for the first time according to a photographing start instruction and determining an initial focal length. Receive the shooting instruction and record the shooting shake data of the shooting device when receiving the shooting instruction, and then determine the fine adjustment focus according to the initial focus adjustment, the shooting shake data and the preset focus adjustment value table. Finally, use the fine-tuning focal length as the shooting focal length to focus and shoot for the second time. After the user presses the camera button, the second focus is performed according to the shaking of the user, thereby reducing the focus shift caused by the shaking when the camera button is pressed, and improving the clarity of the photographed photos. Because before the second focusing, the fine-tuning focal length is determined according to the initial focal length, shooting shake data and the preset focal length adjustment value table, and then the fine-tuning focal length is used as the shooting focal length for the second focusing and shooting, thereby reducing The time for focusing is shortened, and the speed of taking pictures is improved.

Description

technical field [0001] Embodiments of the present invention relate to the field of image technology, and in particular, to a method and device for automatically adjusting focus. Background technique [0002] Nowadays, many electronic products are equipped with high-resolution cameras, and basically have an auto-focus function, which brings a lot of convenience to users. However, apart from scenes with low light, many of the photos taken by users are blurry. The reason for this phenomenon is that the focus function of the camera is not coordinated with the camera function. Because in the prior art, most of the cameras first perform automatic focusing, and then take a snapshot to take pictures, but after taking pictures, the pictures taken still have blurred situations. Contents of the invention [0003] Embodiments of the present invention provide a method and device for automatically adjusting the focus, which are used to solve the problem in the prior art that blurred p...
