Problems solved by technology

Auto focus is to capture some specific elements in the real-time image to focus, such as a person's head portrait and smiling face, but it cannot focus on any point in the image; tap the screen to focus, you can focus on any point on the screen, but you must manually click, and The contacts are not very fine, and it is very inconvenient to operate with both hands for devices with large screens
[0003] In summary, none of the above methods can achieve fully automatic and accurate camera focus

Abstract

The embodiment of the invention discloses a camera focusing method and device. In the embodiment of the present invention, according to the conversion coefficient from the spatial coordinates of the photographing device to the screen and the coordinate difference of the coordinate point where the photographing device is rotated and focused, the corresponding coordinates of the spatial coordinate points mapped on the screen after the photographing device is rotated are obtained, and the focusing point is moved. Go to the position corresponding to the corresponding coordinates and take a photo, which can automatically and accurately focus the photo.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a camera focusing method and device. Background technique [0002] At present, there are many ways for the camera device to focus, such as auto-focus, tapping the screen to focus, and the like. Auto focus is to capture some specific elements in the real-time image to focus, such as a person's head portrait and smiling face, but it cannot focus on any point in the image; tap the screen to focus, you can focus on any point on the screen, but you must manually click, and The contacts are not very fine, and it is very inconvenient to operate with both hands for devices with large screens. [0003] To sum up, none of the above methods can realize fully automatic and accurate camera focusing. Contents of the invention [0004] Embodiments of the present invention provide a camera focusing method and device, which can automatically and accurately focus. [0005] On...
