Abstract

The embodiment of the invention provides a method and device for automatically adjusting focal distance. The method comprises the following steps: performing the first focusing on a lens of a shooting device according to a shooting starting instruction and determining an initial-set focal distance; receiving a shooting instruction and recording shooting jitter data of the shooting device when receiving the shooting instruction, and then determining the fine-set focal distance according to the initial-set focal distance, the shooting jitter data and the preset focal distance setting numerical table; finally performing the second focusing on the shooting focal distance by using the fine-set focal distance and performing the shooting. Since the second focusing is performed according to the jitter of a user after the user presses down a photographing button, the focal distance deviation caused by the jitter when pressing down the photographing button is reduced, and the sharpness of a shot picture is improved. Since the fine-set focal distance is determined according to the initial-set focal distance, the shooting jitter data and the preset focal distance setting numerical table before performing the second focusing, and the second focusing and the shooting are performed by taking the fine-set focal distance as the shooting focal distance, the focus setting time is reduced, and the photographing speed 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...
