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

This abstract first appeared for US patent application 20240337905 titled 'LENS APPARATUS AND IMAGE PICKUP APPARATUS

The patent application describes a lens apparatus with an optical system, a tilting unit, an aperture stop, an aperture stop driving unit, an in-focus information obtaining unit, and a control unit.

• The optical system includes multiple lenses.
• The tilting unit can change the angle of an object plane with respect to the optical axis by moving some of the lenses.
• The aperture stop can adjust the aperture amount.
• The aperture stop driving unit controls the aperture stop.
• The in-focus information obtaining unit captures in-focus information of displaced objects.
• The control unit manages the aperture stop driving unit based on in-focus information and the tilting unit's movements.

Potential Applications: - Photography equipment - Medical imaging devices - Surveillance systems

Problems Solved: - Enhancing focus on tilted objects - Adjusting aperture for different lighting conditions

Benefits: - Improved image quality - Enhanced focus control - Versatile applications in various industries

Commercial Applications: Title: Advanced Lens Apparatus for Precision Imaging This technology can be used in professional photography equipment, medical imaging devices, and surveillance systems, offering superior focus control and image quality. The market implications include increased demand for high-quality imaging solutions in multiple industries.

Questions about Lens Apparatus: 1. How does the tilting unit affect the focus of the lens apparatus? The tilting unit changes the angle of the object plane with respect to the optical axis, allowing for precise focus adjustments on tilted objects.

2. What role does the aperture stop play in the lens apparatus? The aperture stop controls the amount of light entering the optical system, affecting the depth of field and exposure of the images captured.

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.
