ZOOM LENS AND IMAGE PICKUP APPARATUS - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240241354 titled 'ZOOM LENS AND IMAGE PICKUP APPARATUS
The abstract describes a zoom lens with a first lens unit and a rear group including an image stabilizing unit and a focus unit, satisfying a predetermined inequality during zooming.
- First lens unit with negative refractive power
- Rear group with two or more lens units and an aperture stop
- Image stabilizing unit with negative refractive power for stabilization
- Focus unit on the object side of the image stabilizing unit
- Changing distance between lens units during zooming
Potential Applications: - Camera lenses - Surveillance systems - Medical imaging devices
Problems Solved: - Image stabilization during zooming - Maintaining image quality at different zoom levels
Benefits: - Improved image quality - Enhanced stability for clearer photos - Versatile zoom capabilities
Commercial Applications: Title: Advanced Zoom Lens Technology for High-Resolution Imaging This technology can be used in high-end cameras, security systems, and medical equipment to provide superior image quality and stability.
Questions about Zoom Lens Technology: 1. How does the image stabilizing unit contribute to the overall performance of the zoom lens? The image stabilizing unit helps to reduce blur and improve image quality by compensating for movements during zooming.
2. What sets this zoom lens apart from traditional zoom lenses in terms of innovation? This zoom lens incorporates an image stabilizing unit that moves with a component orthogonal to the optical axis, providing enhanced stability and image quality.
Original Abstract Submitted
a zoom lens includes, in order from an object side to an image side, a first lens unit having negative refractive power, and a rear group including two or more lens units, and an aperture stop. the rear group includes an image stabilizing unit having negative refractive power and configured to move with a component in a direction orthogonal to an optical axis during image stabilization, and a focus unit disposed on the object side of the image stabilizing unit. a distance between adjacent lens units changes during zooming. a predetermined inequality is satisfied.
