FOCUSING METHOD AND RELATED PRODUCT

A focusing method and a related product are provided according to implementations of the present disclosure. The method includes the following. A set of FV sampling parameter groups and a set of phase difference defocus value sampling parameter groups are obtained. A first mapping relation between step angles and FVs is determined according to the set of FV sampling parameter groups and a first predetermined fitting scheme, and a second mapping relation between the step angles and defocus values is determined according to the set of defocus value sampling parameter groups and a second predetermined fitting scheme, where the step angles are step angles of a camera driving device of a camera module. A first step angle in a first step angle set is determined according to the first mapping relation, and a second step angle in a second step angle set is determined according to the second mapping relation. Focusing is completed according to the first step angle and the second step angle. In the implementations of the present disclosure, a speed of focusing of the mobile terminal is increased, and service life of focusing-related hardware components is prolonged.
