LENS ASSEMBLY AND ELECTRONIC DEVICE INCLUDING THE SAME - A simplified explanation of the abstract

This abstract first appeared for US patent application 17947285 titled 'LENS ASSEMBLY AND ELECTRONIC DEVICE INCLUDING THE SAME

Simplified Explanation

The abstract describes an electronic device with a lens assembly that includes multiple lens groups. The first lens group has a negative refractive power and consists of at least two lenses. The second lens group has a positive refractive power and can move along the optical axis. The third lens group also has a negative refractive power and can move back and forth along the optical axis. The processor in the device is programmed to increase the focal length of the lens assembly by moving either the second lens group or the third lens group towards the object side during zooming.

  • The electronic device has a lens assembly with multiple lens groups.
  • The first lens group has a negative refractive power and consists of at least two lenses.
  • The second lens group has a positive refractive power and can move along the optical axis.
  • The third lens group has a negative refractive power and can move back and forth along the optical axis.
  • The processor in the device is programmed to increase the focal length of the lens assembly by moving either the second lens group or the third lens group towards the object side during zooming.

Potential applications of this technology:

  • Digital cameras
  • Smartphones
  • Surveillance systems
  • Medical imaging devices

Problems solved by this technology:

  • Provides a compact and versatile lens assembly for electronic devices
  • Enables zooming functionality without the need for additional external lenses

Benefits of this technology:

  • Improved image quality during zooming
  • Compact and lightweight design for portable devices
  • Cost-effective solution for electronic devices with zooming capabilities


Original Abstract Submitted

According to certain embodiments, an electronic device comprises, a processor; and a lens assembly, wherein the lens assembly includes, an image sensor; and a first lens group, a second lens group, and a third lens group; wherein the first lens group has a negative refractive power and includes at least two lenses; wherein the second lens group has a positive refractive power and is configured to move along an optical axis direction between the first lens group and the image sensor, the second lens group including at least two lenses; and wherein the third lens group has a negative refractive power and is configured to move back and forth along the optical axis direction between the second lens group and the image sensor, the third lens group including at least one lens, wherein the processor is configured to increase a focal length of the lens assembly by moving at least one of the second lens group and the third lens group toward an object side in a zooming operation.
