==OPTICAL SYSTEM AND APPARATUS HAVING THE SAME - A simplified explanation of the abstract==


This abstract first appeared for US patent application 18299615 titled 'OPTICAL SYSTEM AND APPARATUS HAVING THE SAME

==Simplified Explanation==

The patent application describes an optical system designed for capturing tilted images.
* The system consists of four lens units arranged in a specific order.
* The first and third lens units can move in a direction perpendicular to the optical axis for tilt image-capturing.
* The object-side lens unit and the second lens unit do not move in this direction.
* The first lens unit has a positive refractive power, while the third lens unit has a negative refractive power.
* This configuration allows for capturing tilted images without moving the entire system.


==Original Abstract Submitted==

An optical system configured to perform tilt image-capturing includes an object-side lens unit, a first lens unit having a positive refractive power, a second lens unit having a positive refractive power, and a third lens unit having a negative refractive power which are arranged in order from an object side. The first lens unit and the third lens unit move in a direction including a component of a direction perpendicular to an optical axis for tilt image-capturing. The object-side lens unit and the second lens unit do not move in a direction including a component of a direction perpendicular to the optical axis for tilt image-capturing.
