ACTUATOR FOR OPTICAL IMAGE STABILIZATION AND CAMERA MODULE INCLUDING ACTUATOR FOR OPTICAL IMAGE STABILIZATION - A simplified explanation of the abstract

This abstract first appeared for US patent application 18212956 titled 'ACTUATOR FOR OPTICAL IMAGE STABILIZATION AND CAMERA MODULE INCLUDING ACTUATOR FOR OPTICAL IMAGE STABILIZATION

Simplified Explanation: The patent application describes an actuator for optical image stabilization that includes a fixed frame, a movable frame, a driving unit, and a sensor substrate with an image sensor.

  • The actuator consists of a fixed frame and a movable frame that can move relative to each other.
  • A driving unit applies a driving force to the movable frame to stabilize the image.
  • The sensor substrate, which includes the image sensor, is connected to the movable frame.
  • The driving unit is composed of sub-driving units with magnets and coils that generate the driving force.
  • The magnets and coils are positioned in a way that allows for efficient stabilization of the image sensor.

Key Features and Innovation:

  • Actuator for optical image stabilization
  • Fixed frame and movable frame design
  • Driving unit with magnets and coils
  • Sensor substrate with image sensor
  • Efficient stabilization mechanism

Potential Applications:

  • Smartphone cameras
  • Digital cameras
  • Video cameras
  • Surveillance cameras
  • Medical imaging devices

Problems Solved:

  • Image blurring due to motion
  • Unstable images in low light conditions
  • Shaky videos
  • Poor image quality in moving vehicles
  • Inaccurate medical imaging results

Benefits:

  • Improved image stabilization
  • Clearer and sharper images
  • Better video quality
  • Enhanced performance in various lighting conditions
  • Accurate medical diagnoses

Commercial Applications: Optical image stabilization technology can be utilized in various commercial applications such as smartphone cameras, digital cameras, video cameras, surveillance systems, and medical imaging devices to enhance image quality and performance.

Questions about Optical Image Stabilization: 1. How does optical image stabilization improve image quality? 2. What are the main components of an actuator for optical image stabilization?


Original Abstract Submitted

An actuator for optical image stabilization includes a fixed frame having an internal space, a movable frame disposed in the fixed frame and configured to be movable relative to the fixed frame, a first driving unit configured to apply a driving force to the movable frame, and a sensor substrate including a moving portion coupled to the movable frame, wherein an image sensor is disposed on the sensor substrate, the first driving unit includes a first sub-driving unit including a first magnet disposed on the fixed frame and a first coil disposed to face the first magnet, and a second sub-driving unit including a second magnet disposed on the fixed frame and a second coil disposed to face the second magnet, and a portion of the first magnet overlaps a portion of the second magnet in a direction perpendicular to an imaging surface of the image sensor.
