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

Embodiments of the invention disclose a photographing focusing method and device. In the embodiments of the invention, a corresponding coordinate of a space coordinate point mapped onto the screen after the rotation of the photographing device is obtained in accordance with a conversion coefficient of a space coordinate to a screen and a coordinate difference between coordinate points at which the photographing device focuses by rotating, and the focusing point is moved to a position corresponding to the coordinate for photographing, and thus automatic and correct photographing focusing can be implemented.

Description

Technical field [0001] The present invention relates to the technical field of image processing, in particular to a photographing focusing method and device. Background technique [0002] At present, there are many methods for camera focusing, such as auto focusing, tapping the screen to focus and so on. Auto focus is to capture some specific elements in the real-time image to focus, such as a person's avatar, smiling face, but can not focus on any point in the image; tap the screen to focus, you can focus on any point on the screen, but you must click manually, and The contacts are not too fine, and it is very inconvenient for devices with large screens to operate with hands. [0003] In summary, none of the above methods can achieve fully automatic and accurate camera focusing. Summary of the invention [0004] The embodiments of the present invention provide a camera focusing method and device, which can automatically and accurately perform focusing. [0005] On the one hand, an...
