ZOOM LENS AND IMAGING APPARATUS - A simplified explanation of the abstract
This abstract first appeared for US patent application 18750114 titled 'ZOOM LENS AND IMAGING APPARATUS
The zoom lens described in the patent application consists of multiple lens groups with specific refractive powers and movements during zooming and image blur correction.
- The first lens group has a positive refractive power and moves during zooming.
- The second lens group includes a front group that does not move during image blur correction and an image stabilization group with a negative refractive power that moves during image blur correction.
- The zoom lens satisfies predetermined conditional expressions.
Potential Applications: This technology can be used in cameras, camcorders, and other optical devices that require zoom capabilities with image stabilization and image blur correction.
Problems Solved: This technology addresses the challenge of maintaining image quality and stability while zooming in on objects, especially in situations where image blur correction is necessary.
Benefits: The zoom lens design improves image quality by providing image stabilization and correcting image blur, resulting in clearer and sharper photos and videos.
Commercial Applications: This technology can be applied in the consumer electronics industry for digital cameras, smartphones, and other devices with zoom capabilities. It can also be used in professional photography and videography equipment.
Questions about the Zoom Lens Technology: 1. How does the movement of the lens groups during zooming affect image quality? 2. What are the specific conditional expressions that the zoom lens must satisfy for optimal performance?
Original Abstract Submitted
The zoom lens includes, in order from a position closest to an object side to an image side: a first lens group that has a positive refractive power; a second lens group that has a negative refractive power; an intermediate group that has a positive refractive power; and a subsequent group that has a negative refractive power. The first lens group moves during zooming. The second lens group consists of, in order from the object side to the image side, a front group of the second lens group which does not move during image blur correction and an image stabilization group which moves during image blur correction and has a negative refractive power. The zoom lens satisfies predetermined conditional expressions.
