AI Technical Summary

Technical Problem

Existing camera modules struggle to balance optical performance and image stabilization in thinner, lighter, and full-screen devices, and the traditional off-center design leads to lens optical axis shift and decreased image quality.

Method used

It adopts a full-system synchronous eccentric design, with the lens and housing geometric center set off-center. All components in the carrier, focusing module, and image stabilization mechanism that move synchronously with the lens coincide with the lens geometric center. Combined with the ball bearing assembly, trapezoidal groove structure, and magnetic preload, it achieves independent sliding and focusing movements.

Benefits of technology

It achieves perfect adaptation in irregular spaces, avoids image tilt and distortion, improves image quality and image stabilization accuracy, reduces motion drag, and extends the life of the image stabilization mechanism.

Abstract

This invention relates to the field of camera equipment technology, disclosing an off-center camera module structure that solves the problem of excessive core space occupied by traditional centrally symmetrical camera modules. It includes a housing and a lens assembly. The housing contains a focusing module, an image stabilization mechanism, and a drive control module. The lens assembly includes a lens and a carrier, with the carrier slidably mounted on the housing. The focusing module is located between the image stabilization mechanism and the housing. The drive control module controls the operation of the focusing module and the image stabilization mechanism. The geometric center of the lens and the housing is off-center, and the components in the carrier, focusing module, and image stabilization mechanism that move synchronously with the lens coincide with the geometric center of the lens. Viewed from above along the optical axis, the distance between one edge of the lens and the housing is different from the distance between the other edge. Viewed from the front along a direction perpendicular to the optical axis, the thickness of the assembled camera module is different on both sides. This invention adopts a system-wide synchronous off-center design, utilizing the unused space at the corners of the phone to achieve image quality and performance comparable to centrally symmetrical modules.
