FILTER CHANGE ASSEMBLY FOR CAMERA MODULE WHICH USES ELECTROMAGNETIC ROTATING DEVICE, AND OPERATING METHOD THEREOF

摘要

The present invention relates to a filter change assembly for camera module which uses an electromagnetic rotating device, and more specifically to a filter change assembly which: excludes an unnecessary operation from the filter change assembly by driving an electromagnetic rotating device after detecting the environment through a camera module; and does not veil a screen by shortening an operation time thereof. The filter change assembly disclosed in the invention comprises: an assembly base that supports an electromagnet rotation inducing member; the electromagnetic rotation inducing member that forms an electronic field for rotating the electromagnetic rotating device; the electromagnetic rotating device that rotates by an electromagnetic force when electricity flows into the electromagnet rotation inducing member to form the electric field; a plate that comprises a hollow portion for changing the rotation into linear motion of the electromagnetic rotating device and transferring the light passing through a lens to a CCD; and a filter holder slide that has a glass filter and an infrared ray removing filter inserted into an internal hollow portion thereof and performs linear motion through the guidance of the plate.
