Problems solved by technology

[0006] The small camera module has a disadvantage that it can affect external devices because it forms a large magnetic field to the periphery
Especially in the development of mobile devices with dual cameras, there is a limitation that the two camera modules must be separated by a predetermined distance or more

Abstract

Disclosed is an OIS camera module including: a module base; a lens carrier movably mounted on the module base; and at least one OIS actuator controlling movement of the lens carrier in a horizontal direction vertical to an optical axis of the lens carrier, and each OIS actuator includes a coil and a magnet unit, and a main magnetic flux line direction of the magnet unit is aligned parallel to theoptical axis. The OIS camera module disclosed in the invention can reduce influence exerted on an external part by a magnetic field to a maximum degree.

Description

technical field [0001] The invention relates to a camera module with an anti-shake function, in particular to an OIS camera module and a dual camera system which are beneficial for configuring dual cameras. Background technique [0002] A camera module with an auto-focusing (AF: auto-focusing) function in which the lens automatically adjusts the focus when shooting a subject is not only suitable for general digital video cameras, but also widely used in mobile devices such as mobile phones and tablets. [0003] At present, not only the automatic focus (AF) function is adopted, but the camera module also adopts the anti-shake function. Anti-shake methods can be divided into electronic and optical. Electronic Image Stabilizer (EIS: Electronic Image Stabilizer) is a method of correcting and processing the image signal output from the image sensor by a program. The optical image stabilization method (OIS: Optical Image Stabilizer) is a method of mechanically adjusting the posi...
