ZOOM LENS, IMAGE PICKUP APPARATUS, AND IMAGE PICKUP SYSTEM - A simplified explanation of the abstract
This abstract first appeared for US patent application 18493844 titled 'ZOOM LENS, IMAGE PICKUP APPARATUS, AND IMAGE PICKUP SYSTEM
Simplified Explanation
The patent application describes a zoom lens with multiple lens units that change position during zooming and focusing, providing high-quality images across a range of focal lengths.
- The zoom lens consists of a first lens unit with negative refractive power, a second lens unit with positive refractive power, a third lens unit with negative refractive power, and a fourth lens unit with positive refractive power.
- The distance between adjacent lens units changes during zooming from wide-angle to telephoto, with the first and fourth lens units fixed relative to the image plane.
- The second lens unit is made up of four or more spherical lenses, and a specific inequality is satisfied to ensure optimal performance.
Potential Applications
This technology could be used in digital cameras, camcorders, and other optical devices that require high-quality zoom lenses for capturing images and videos.
Problems Solved
This innovation solves the problem of maintaining image quality and focus accuracy while zooming and focusing, providing users with clear and sharp images across different focal lengths.
Benefits

Original Abstract Submitted
A zoom lens includes a plurality of lens units that consist of, in order from an object side to an image side, a first lens unit having negative refractive power, a second lens unit having positive refractive power, a third lens unit having negative refractive power, and a fourth lens unit having positive refractive power. A distance between adjacent lens units changes during zooming from a wide-angle end to a telephoto end. During zooming from a wide-angle end to a telephoto end, the first lens unit and the fourth lens unit are fixed relative to an image plane, and the third lens unit moves to the object side. During focusing from infinity to a shortest distance, the first lens unit is fixed relative to the image plane. The second lens unit consists of four or more spherical lenses. A predetermined inequality is satisfied.
