BACKGROUND OF THE INVENTION

Field of the Invention

The present disclosure relates to an optical system, and in particular it relates to an optical system having a liquid lens.

Description of the Related Art

As technology has progressed, many kinds of electronic devices such as smartphones have begun to include the functionality of digital photography or video recording. A user can operate the electronic device to capture various images with a camera module that is included in the electronic device.

Today's design of electronic devices continues to move toward the trend of miniaturization so that the various components of the camera module or its structure must also be continuously reduced, so as to achieve the purpose of miniaturization. In general, a driving mechanism of the camera module has a camera lens holder configured to hold a camera lens, and the driving mechanism can have the functions of auto focusing or optical image stabilization. However, although the existing driving mechanism can achieve the aforementioned functions of photographing or video recording, they still cannot meet all the needs of miniaturization.

Therefore, how to design a camera module that can perform autofocus, optical image stabilization, and miniaturization at the same time is a topic nowadays that needs to be discussed and solved.

BRIEF SUMMARY OF INVENTION

In view of the aforementioned problems, the object of the invention is to provide an optical system that includes a fixed assembly, a plurality of movable members, and a plurality of driving assemblies respectively connected to the movable members. The movable members are connected to an optical element and movable relative to the fixed assembly. The driving assemblies respectively drive the movable members to move relative to the fixed assembly in different time intervals.
