Miniature optical anti-vibration camera module

Abstract

The invention relates to the technical field of a camera, and especially relates to a miniature optical anti-vibration camera module. The module at least is equipped with a lens, an automatic focusing voice coil motor, an image sensor module and a miniature memory alloy optical anti-vibration actuator. The lens is fixed on the automatic focusing voice coil motor. The image sensor module sends an image obtained by the lens. The automatic focusing voice coil motor is fixed on the miniature memory alloy optical anti-vibration actuator. A control chip drives the automatic focusing voice coil motor to move based on length change of a memory alloy wire on the miniature memory alloy optical anti-vibration actuator, thereby realizing vibration compensation of the lens. According to the module, the module structure is simplified, the cost is reduced, the power consumption is low, through novel layout of a flexible circuit board, the relative movement problem of a moving board and a fixed board is solved, multi-line connection is realized, the technology is simple, the structure stability is high, the integrated height of the module will not be increased, and the product structure is light and miniature.

AI Technical Summary

Benefits of technology

This technology improves imaging by controlling an automatic focus (AF) camera's diaphragm movements during photography without adding extra components like motors or sensors. It achieves this through changing the distance between two wires attached at different points along its surface. Additionally, there are also features such as a miniature position sensor to improve accuracy when adjusting focusing settings. Overall, these improvements make cameras more efficient and effective than older models with mechanical parts.

Problems solved by technology

Technological Problem: Current Micro-Optical Anti-Shake Camera Module (MOSA) designs have issues such as lenses being unable to maintain their stability when subjecting them to external forces like vibration. These limitations result in poor images taken through these systems.
