ZOOM LENS AND IMAGE PICKUP APPARATUS - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240264419 titled 'ZOOM LENS AND IMAGE PICKUP APPARATUS
The abstract describes a zoom lens with multiple lens units that change position during zooming, except for the second lens unit which remains stationary. The second lens unit moves in a direction orthogonal to the optical axis for image stabilization, and the lens closest to the object in this unit has positive refractive power.
- First lens unit with positive refractive power
- Second lens unit with negative refractive power
- Rear group with one or more lens units
- Changing distance between lens units during zooming
- Second lens unit stationary during zooming
- Movement of part of second lens unit for image stabilization
- Lens closest to object in second unit has positive refractive power
- Satisfies a predetermined inequality
Potential Applications: - Camera lenses - Surveillance systems - Medical imaging devices
Problems Solved: - Improved image stabilization - Enhanced zoom capabilities - Better optical performance
Benefits: - Clearer images - Stable footage - Versatile zooming options
Commercial Applications: Title: Advanced Zoom Lens Technology for Enhanced Imaging This technology can be used in professional photography equipment, security cameras, and medical imaging devices, offering superior image quality and stability.
Questions about Zoom Lens Technology: 1. How does the second lens unit contribute to image stabilization? The second lens unit moves in a direction orthogonal to the optical axis to stabilize the image. 2. What is the significance of the predetermined inequality being satisfied in this zoom lens design? The predetermined inequality being satisfied ensures optimal performance and image quality.
Original Abstract Submitted
a zoom lens includes a plurality of lens units, the plurality of lens units consisting of, in order from an object side to an image side, a first lens unit having positive refractive power, a second lens unit having negative refractive power, and a rear group consisting of one or more lens units. a distance between adjacent lens units changes during zooming, and the second lens unit does not move for zooming. at least a part of the second lens unit moves in a direction including a component orthogonal to an optical axis during image stabilization. a lens disposed closest to an object in the second lens unit has positive refractive power. a predetermined inequality is satisfied.
