CAMERA MODULE AND VEHICLE COMPRISING SAME - A simplified explanation of the abstract

This abstract first appeared for US patent application 18559208 titled 'CAMERA MODULE AND VEHICLE COMPRISING SAME

The camera module described in this patent application consists of a lens barrel with a through hole, along with three lenses aligned with the optical axis from the object side to the sensor side. The second lens has a lower refractive index than the first lens and includes a flange portion that contacts the inner surface of the lens barrel.

The second lens has a different radius of curvature on the object-side third surface and the sensor-side fourth surface.
The first contact surface where the flange portion of the second lens contacts the inner surface of the lens barrel is 20% to 50% of the thickness of the flange portion.
The center of the first contact surface may be closer to the side with a greater radius of curvature among the third and fourth surfaces.

Potential Applications: - This technology can be used in various camera systems, including smartphones, digital cameras, and surveillance cameras. - It can improve the optical performance and image quality of the camera module.

Problems Solved: - Enhances the optical performance of camera modules by optimizing the alignment and materials of the lenses. - Improves image quality by reducing aberrations and distortions in captured images.

Benefits: - Enhanced image quality and optical performance. - Improved accuracy and clarity in captured images. - Potential cost savings in camera manufacturing.

Commercial Applications: Title: Advanced Camera Module Technology for Enhanced Image Quality This technology can be applied in smartphone cameras, digital cameras, surveillance systems, and other imaging devices. It can benefit manufacturers looking to improve the performance of their camera modules and enhance the overall user experience.

Questions about Camera Module Technology: 1. How does the refractive index of the second lens impact the overall performance of the camera module? The lower refractive index of the second lens helps reduce aberrations and improve image quality by optimizing the light transmission through the lens system.

2. What are the key factors to consider when designing a camera module with multiple lenses? When designing a camera module with multiple lenses, factors such as material selection, lens alignment, and curvature of the lens surfaces play a crucial role in determining the optical performance and image quality of the system.

Original Abstract Submitted

The camera module disclosed in the embodiment of the invention includes a lens barrel having a through hole therein; and first, second and third lenses coupled to the through hole of the lens barrel and aligned with an optical axis from an object side to a sensor side. The materials of the first and second lenses are different, a refractive index of the second lens is lower than a refractive index of the first lens, the second lens includes a flange portion extending from the optical axis toward an inner surface of the lens barrel, and a length of a first contact surface in which the flange portion of the second lens contacts the inner surface of the lens barrel is 20% to 50% of a thickness of the flange portion. An object-side third surface and a sensor-side fourth surface of the second lens have different radii of curvature on the optical axis, and a center of the first contact surface where the flange portion of the second lens contacts the inner surface of the lens barrel may be located closer to a side having a greater radius of curvature among the third surface and the fourth surface based on a center of the thickness of the flange portion.
