Problems solved by technology
[0002] With the rapid development of smart terminal equipment, people's requirements for third-party camera applications are increasing. Under the existing technology, in the current three-party applications, only the user's camera focus function can be supported, and the subject cannot be tracked. Update the focus area. When shooting a moving object or the electronic device shakes during the shooting process, the object is likely to be predicted incorrectly or the recognition fails, which will cause the focus to fail to form a blurred out-of-focus image, which will cause the three-party camera application to shoot moving objects. Can't get better effect when using

The embodiment of the present application discloses a focus tracking shooting method and related products, including a media service module and an operating system, the application layer of the operating system is provided with a third-party camera application, and the hardware abstraction layer of the operating system is provided with a camera hardware abstraction module; the method; It includes: a third-party camera application determines a framing area, and sends the framing area to the media service module, the media service module extracts the focal area feature according to the framing area, and sends the focal area feature to the camera hardware abstraction module, and the camera hardware abstraction module obtains the focal area. The real-time data of the feature, predict the motion trend information of the camera according to the real-time data, process the motion trend information, determine the camera focus parameters, and send the camera focus parameters to the third-party camera application. The third-party camera application tracks the viewing area according to the camera focus parameters. Focus processing, effectively improve the clarity and accuracy of the focus shooting, which is conducive to enhancing the use effect.
Description
technical field [0001] The present application relates to the technical field of electronic equipment, and in particular to a focus tracking shooting method and related products. Background technique [0002] With the rapid development of smart terminal equipment, people's requirements for third-party camera applications are increasing. Under the existing technology, in the current three-party applications, only the user's camera focus function can be supported, and the subject cannot be tracked. Update the focus area. When shooting a moving object or the electronic device shakes during the shooting process, the object is likely to be predicted incorrectly or the recognition fails, which will cause the focus to fail to form a blurred out-of-focus image, which will cause the three-party camera application to shoot moving objects. When it is not possible to obtain better results. Contents of the invention [0003] Embodiments of the present application provide a focus track...
