Abstract

The present application relates to a target focus tracking method, device, electronic equipment, and computer-readable storage medium. The method includes: receiving a shooting instruction, controlling the camera to collect multiple frames of images according to the shooting instruction; Segmenting the target subject on the preview image to obtain a target subject mask map; determining the circumscribed area of ​​the target subject mask map according to the area parameters of the target subject mask map; according to the target subject mask map and the circumscribed area A focus tracking prediction frame of the current preview image is generated, and a focus tracking process is performed on a next frame image by using the focus tracking prediction frame. By adopting the method, the focus tracking process can be performed on the target subject according to the focus tracking prediction frame of each frame of image, so that the target subject can be accurately and continuously tracked, and the accuracy of focus tracking can be effectively improved.

Description

technical field [0001] The present application relates to the field of computer technology, and in particular, to a method and apparatus for tracking focus, an electronic device, and a computer-readable storage medium. Background technique [0002] With the development of photography technology, photography technology is widely used in various electronic devices. Users can shoot through electronic devices, and can focus on the subject when shooting. At present, some tracking methods based on visual target tracking, such as optical flow tracking and signal prediction tracking, have emerged. In the scene where the main target is moving, blocked, and the illumination changes greatly, it is easy to fail to focus, and the user needs to manually focus frequently. SUMMARY OF THE INVENTION [0003] Embodiments of the present application provide a method, device, electronic device, and computer-readable storage medium for tracking focus, which can effectively improve the tracking...
