Abstract: Embodiments of this application disclose a focusing method and apparatus applied to a terminal device, and the terminal device. The method includes: detecting whether a current frame includes a target object, where the target object is one of preset objects on which focusing needs to be performed; when the current frame includes the target object, determining whether the target object is in a motion state; when the target object is in the motion state, performing tracking focusing by using phase detection PD information with a variable filtering length; and when the target object is in a static state, performing stable focusing by using PD information obtained in an adaptive fixed PD configuration mode.
