Embodiment Construction

[0034] In order to make the object, technical solution and advantages of the present invention more clear and definite, the present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0035] The first embodiment of the present invention provides a camera focusing method based on a dynamic environment, such as figure 1 shown, including:

[0036] S1: After receiving a photographing instruction, obtain brightness signals of multiple preset coordinate points in a preset photographing preset area.

[0037] When the target object is in motion, you don’t need to click the image on the display screen to focus, just press the camera button, the screen receives a camera command, and obtains the brightness signals of multiple preset coordinate points in the preset camera preset...

Abstract

The present invention provides a camera focusing method based on a dynamic environment, a mobile terminal and a storage medium. When taking a photo, the brightness signals of a plurality of preset coordinate points in a preset camera preset area are taken, and the pulse corresponding to the brightness signal is obtained by processing. signal; compare the pulse signals of adjacent preset coordinate points, filter out a plurality of adjacent preset coordinate points with the smallest amplitude difference, and use the center point of the area formed by the plurality of preset coordinate points as the target The focus point of the object, focus on the target object and take a photo. The method provided by the invention reflects the main features of the object according to the fact that the brightness signal of the target object is basically unchanged during the dynamic state, so that when the dynamic target object is photographed, there is no need to repeat focusing, as long as the target object is within a predetermined area, fast focusing can be achieved Taking pictures, the invention can improve the user experience, improve the picture taking technology of the mobile terminal, enrich the picture taking function of the mobile terminal, and promote the development of innovative technology of the mobile terminal.

Description

technical field [0001] The present invention relates to the technical field of photographing, and in particular to a dynamic environment-based photographic focusing method, a terminal and a storage medium. Background technique [0002] At present, the camera function of mobile terminals is frequently used in daily life. In order to take a clear photo, it is necessary to focus on the target of the photo. It is impossible to quickly and repeatedly focus on the photographing target, that is, during the photographing and focusing, the photographing subject cannot be quickly focused in a short period of time, so the photographing target cannot be quickly and accurately focused, thereby failing to take a clear image. [0003] Therefore, prior art awaits further improvement. Contents of the invention [0004] In view of the deficiencies in the above-mentioned prior art, the present invention provides a camera focusing method, terminal and storage medium based on a dynamic enviro...
