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 invention discloses a focus tracking shooting method and a related product, a media service module and an operating system are included, an application layer of the operating system is provided with a third-party camera application, and a hardware abstraction layer of the operating system is provided with a camera hardware abstraction module. The method comprises the following steps that the third-party camera application determines a framing area, sends the framing area to the media service module, the media service module extracts features of a focusing area according to the framing area; the focusing area features are sent to a camera hardware abstraction module; the camera hardware abstraction module acquires real-time data of the focusing area characteristics; motion trend information of the camera is predicted according to the real-time data; the motion trend information is processed, the camera focusing parameters are determined, the camera focusing parameters are sent to the third-party camera application, and the third-party camera application performs focus tracking processing on the framing area according to the camera focusing parameters, so that the definition and accuracy of focus tracking shooting are effectively improved, and the use effect is enhanced.
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. Sometimes it is not possible to obtain better results. Contents of the invention [0003] Embodiments of the present application provide a focus ...
