LENS APPARATUS AND IMAGE PICKUP APPARATUS - A simplified explanation of the abstract

This abstract first appeared for US patent application 18626426 titled 'LENS APPARATUS AND IMAGE PICKUP APPARATUS

Simplified Explanation: The patent application describes a lens apparatus with a tilting unit that can change the angle of an object plane with respect to the optical axis by displacing some lenses. The apparatus also includes an aperture stop that can adjust the aperture amount, an aperture stop driving unit, an in-focus information obtaining unit, and a control unit.

• The lens apparatus includes a tilting unit that can change the angle of an object plane with respect to the optical axis by displacing some lenses.
• An aperture stop is included to adjust the aperture amount, with a driving unit to control it.
• An in-focus information obtaining unit gathers information about the focus of objects.
• A control unit manages the aperture stop driving unit based on the in-focus information and the tilting unit's drive information.

Potential Applications: This technology could be used in various optical systems where precise control over the angle of the object plane and aperture amount is required, such as in photography, microscopy, and machine vision systems.

Problems Solved: This technology addresses the need for precise control over the angle of the object plane and aperture amount in optical systems, improving image quality and focus accuracy.

Benefits: The benefits of this technology include enhanced image quality, improved focus accuracy, and increased flexibility in optical system design.

Commercial Applications: This technology could be applied in industries such as photography, microscopy, medical imaging, and machine vision systems, where precise control over focus and aperture is crucial for high-quality imaging.

Questions about Lens Apparatus: 1. How does the tilting unit in the lens apparatus work to change the angle of the object plane? 2. What are the potential benefits of using the in-focus information obtained by the apparatus in optical systems?

Original Abstract Submitted

Provided is a lens apparatus including: an optical system including: an optical system including a plurality of lenses; a tilting unit configured to change an angle of an object plane to an optical axis about with respect to an axis of rotation as a center by displacing at least a part some of the plurality of lenses; an aperture stop having configured to change an aperture amount which is changeable; an aperture stop driving unit configured to drive the aperture stop to change the aperture amount by driving the aperture stop; an in-focus information obtaining unit configured to obtain a first in-focus information of a first object which is displaced from the axis of rotation; and a control unit configured to control the aperture stop driving unit based on the first in-focus information and a drive information of the tilting unit.
