Optical Image Stabilization with Voice Coil Motor for Moving Image Sensor - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240214684 titled 'Optical Image Stabilization with Voice Coil Motor for Moving Image Sensor
Simplified Explanation:
This patent application describes a camera with autofocus and optical image stabilization mechanisms using voice coil motors and magnets to move the lens and image sensor carrier, respectively.
- The camera includes a camera actuator with an autofocus voice coil motor (VCM) that moves a lens carrier in the direction of the optical axis of the lens.
- Magnets are mounted to the base of the camera to interact with the VCM and produce the necessary forces for lens movement.
- The optical image stabilization (OIS) mechanism consists of an image sensor carrier that moves orthogonally to the optical axis, controlled by OIS coils within the magnetic fields of the magnets.
Key Features and Innovation:
- Autofocus mechanism using a VCM for precise lens movement.
- Optical image stabilization system with an image sensor carrier and OIS coils.
- Integration of magnets for generating forces to control lens and image sensor movement.
Potential Applications:
- Digital cameras
- Smartphone cameras
- Surveillance cameras
Problems Solved:
- Ensures sharp and focused images
- Reduces blurriness in photos and videos
- Improves stability for clear and steady shots
Benefits:
- Enhanced image quality
- Improved autofocus performance
- Better stabilization for smoother videos
Commercial Applications:
The technology can be utilized in various consumer electronics products such as smartphones, digital cameras, and security cameras to enhance image quality and stability, catering to a wide range of users in the photography and videography market.
Questions about Camera Technology:
1. How does the autofocus mechanism in this camera differ from traditional autofocus systems? 2. What are the advantages of using voice coil motors for lens movement in cameras?
Original Abstract Submitted
a camera includes a camera actuator having autofocus (af) voice coil motor (vcm) with a lens carrier mounting attachment moveably mounted to a base, magnets mounted to the base, and an af coil fixedly mounted to the lens carrier mounting attachment for producing forces for moving a lens carrier in a direction of an optical axis of a lens of the lens carrier. the magnets may include a pair of first magnets laterally spaced along a first side of the camera and a pair of second magnets laterally spaced along a second side of the camera opposite the first side. the optical image stabilization (ois) vcm includes an image sensor carrier moveably mounted to the base, and ois coils moveably mounted to the image sensor carrier within the magnetic fields of the magnets, for producing forces for moving the image sensor carrier in directions orthogonal to the optical axis.
