Title:
FOCUSING APPARATUS AND METHOD, AND ELECTRONIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/082699
Kind Code:
A1
Abstract:
Embodiments of the present application provide a focusing apparatus and method, and an electronic device, which are applicable to the technical field of information. The focusing apparatus comprises a lens, a control module and a driving module. The control module is used for acquiring attribute information of the lens; determining a target stroke of the driving module according to the attribute information, wherein the target stroke is smaller than the total stroke of the driving module; and controlling the driving module to advance in the target stroke so as to drive the lens or a sensor to move, thereby realizing focusing. According to the solution of the present application, the control module acquires the attribute information of the lens, determines the target stroke of the corresponding driving module according to the attribute information of the lens, and thus controls the driving module to advance in the target stroke to drive the lens or the sensor to move to implement focusing. Because the target stroke is smaller than the total stroke of the driving module, a moving range of the driving module is reduced in the focusing process, and the focusing efficiency is improved.
