CAMERA MODULE AND ELECTRONIC DEVICE INCLUDING THE SAME - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240353689 titled 'CAMERA MODULE AND ELECTRONIC DEVICE INCLUDING THE SAME
The abstract describes a patent application for a camera module in an electronic device that includes a lens assembly, an image sensor, and an optical image stabilization (OIS) driving unit.
- The OIS driving unit provides force for the lens assembly or image sensor to move in a direction perpendicular to the optical axis or to rotate about the optical axis.
- The OIS driving unit includes an OIS carrier that transports the lens assembly or image sensor based on its movement.
- The OIS driving unit also includes first axis drive coils, a first magnet with at least two polarities, first position sensors, and at least one second position sensor.
- The first and second position sensors measure the position of the first magnet in different directions to control the movement of the lens assembly or image sensor.
Potential Applications: - Mobile phones - Digital cameras - Surveillance cameras
Problems Solved: - Reducing image blurring due to camera movement - Improving image quality in low light conditions
Benefits: - Enhanced image stabilization - Improved image quality - Better low-light performance
Commercial Applications: Title: Advanced Image Stabilization Technology for Electronic Devices This technology can be used in smartphones, digital cameras, and security cameras to provide superior image stabilization, resulting in clearer and sharper images. This innovation can attract consumers looking for high-quality photography and video capabilities in their devices.
Prior Art: Prior art related to this technology may include patents or research papers on optical image stabilization systems in camera modules.
Frequently Updated Research: Researchers are constantly working on improving image stabilization technology in camera modules to enhance the overall image quality and user experience.
