Focusing method and terminal
A focusing method and a terminal are provided. The method includes the following. A set of FV sampling parameter groups and a set of 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. 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.
