Abstract
A method for adjusting lens position, includes: controlling a lens in a photographing component to be sequentially located at m first lens positions during a focusing process, and acquiring a first definition of an image captured by the photographing component at each of the first lens positions, where m≥3; selecting a first relationship curve in a focusing curve library according to a matching condition, the focusing curve library including at least two relationship curves between definitions and lens positions captured at different focusing distances, and the matching condition being used to indicate a degree of similarity between the m first lens positions as well as the first definitions and the relationship curves; and controlling the lens to be located at a target lens position corresponding to a maximum definition indicated by the first relationship curve.
