MULTIFOCAL CAMERA BY REFRACTIVE INSERTION AND REMOVAL MECHANISM - A simplified explanation of the abstract
This abstract first appeared for US patent application 17837551 titled 'MULTIFOCAL CAMERA BY REFRACTIVE INSERTION AND REMOVAL MECHANISM
Simplified Explanation
The patent application describes an information handling system camera with a rapid focus capability for near and far objects. This is achieved by selectively inserting and removing a refractive material between the camera lens and image sensor to adjust the focusing distance.
- The camera uses a refractive material to adjust the focusing distance between the lens and image sensor.
- When focusing on far objects, a refractive material with specific properties is inserted to achieve instant focus.
- For near objects, the refractive material is removed or replaced with a thinner material to quickly achieve focus.
- A voice coil motor or other actuator can be used to fine-tune the focus when needed.
- In an alternative embodiment, focus is solely achieved by inserting and retracting the refractive material, eliminating the need for a lens actuator.
Potential Applications
- This technology can be applied to various information handling system cameras, such as smartphones, tablets, or digital cameras.
- It can improve the speed and accuracy of focusing in photography and videography applications.
- The rapid focus capability can be beneficial in capturing fast-moving objects or in situations where quick adjustments in focus are required.
Problems Solved
- The technology solves the problem of slow focusing times associated with traditional lens actuator-based focus systems.
- It provides a rapid focus capability for both near and far objects, enhancing the overall user experience in capturing images or videos.
Benefits
- The use of a refractive material allows for instant focus adjustment, reducing the time required to achieve focus.
- The ability to quickly switch between near and far object focus improves the versatility and efficiency of the camera.
- The elimination of a lens actuator in the alternative embodiment simplifies the camera design and potentially reduces manufacturing costs.
Original Abstract Submitted
An information handling system camera that includes a rapid focus capability for near and far objects by selectively inserting and removing a refractive material between the camera lens and image sensor to effectively adjust the camera focusing distance. When far object focus is desired, a refractive material of predefined properties is inserted to enable an instant focus of the far object to the image sensor. When a near object focus is desired, the refractive material is removed (or replaced with a thinner material) to rapidly achieve focus. In addition, a voice coil motor or other actuator fine tunes the focus when desired. In one alternative embodiment, focus is performed only with the insertion and retraction of the refractive material so that no lens actuator is included in the camera. The refractive material extends the back focal distance between the lens and image sensor relative to the back focal distance without the refractive material. Rapid insertion of refractive material shortens the time to adjust focus relative to focus time associated with actuator-based lens movement focus.
