This application provides a shooting method and a related device. The shooting method may be applied to an electronic device with a camera lens. In the shooting method, the electronic device may output a RAW image through the camera lens, and divide the image into three paths of data streams through an image processor. The three paths of data streams are respectively data streams of a panorama path, a focus tracking path, and a detection path respectively. After stabilization processing, the data stream of the panorama path is used to display and preview a large window of a camera application interface. After human body detection and successful focus tracking, information about a human body cropping frame may be output, through the data stream of the detection path, to the focus tracking path for cropping a human body frame. After stabilization processing, smoothing processing, and cropping processing, the data stream of the focus tracking path may be used to display and preview a small window of the camera application interface. It may be understood that related processing on the three data streams is performed in a camera software architecture, and does not depend on a platform. This greatly facilitates transplantation, development, and the reuse at another platform at a later stage.
