Abstract
Examples in this application disclose a focusing method and apparatus applied to a terminal device, and the terminal device. One example 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, a determination is made as to whether the target object is in a motion state. When the target object is in the motion state, tracking focusing is performed by using phase detection PD information with a variable filtering length. When the target object is in a static state, stable focusing is performed by using PD information obtained in an adaptive fixed PD configuration mode.
