Abstract

The invention relates to a lens driving device with a shake compensation function, and the device comprises a base, a focusing part arranged on the base and supported by the base, an outer cover covering the periphery of the focusing part, and a shake compensation driving device arranged between the focusing part and the base or the outer cover. The device is characterized in that the focusing part is movably connected with the outer cover or the base through a connecting assembly; the focusing part is used for bearing an optical lens and realizing a focusing function; the connecting assembly comprises a friction supporting pair which is arranged on the base and is used for bearing the focusing part and enabling the focusing part to be connected with the base in a sliding manner, and a reed which is used for elastically connecting the outer cover or the base with the focusing part; the connecting assembly allows the focusing part to move relative to the base in the direction perpendicular to the optical axis of the optical lens. According to the lens driving device with the shake compensation function, a brand new lens driving structure different from a traditional suspension scheme and an SMA scheme is adopted, optical anti-shake is achieved, and the lens driving device has the advantages of being excellent in anti-shake function, stable and reliable in effect and easy to assemble.

Description

technical field [0001] The invention relates to the field of optical photography, in particular to a lens driving device with shake compensation function, a camera and an electronic device. Background technique [0002] Optical Image Stabilization: The moment the photographer presses the shutter, the camera will shake slightly and the image will be blurred. Optical image stabilization refers to the setting of optical components, such as lens settings, in cameras or other similar imaging instruments to avoid or reduce the phenomenon of instrument shake that occurs during the process of capturing optical signals, thereby improving image quality. Small movements are detected by a gyroscope inside the lens, and a signal is sent to a microprocessor. Afterwards, the processor immediately calculates the amount of displacement that needs to be compensated, and then through the compensation lens group, compensates according to the shaking direction and displacement of the lens, so a...
