Camera modules with lens drive device

Modules de camera

Abstract

A camera module has a plurality of lenses aligned along an optic axis that receive and transmit light from a scene being imaged by the camera module. At least one lens is mounted on a platform which is movable along the optic axis and is moved by action of a piezoelectric motor. Optionally, at least one lens is mounted on a second platform which is movable along the optic axis. The second platform may be driven by a second piezoelectric motor or moved by action of the first platform.
L'invention concerne un module de caméra équipé de plusieurs lentilles alignées le long d'un axe optique qui reçoivent et transmettent la lumière d'une scène imagée par ledit module de caméra. Au moins une lentille est montée sur une plate-forme mobile le long de l'axe optique et se déplaçant par l'action d'un moteur piézo-électrique. Eventuellement, au moins une lentille est montée sur une seconde plate-forme mobile le long de l'axe optique. Ladite seconde plate-forme peut être entraînée par un second moteur piézo-électrique ou se déplacer par l'action de la première plate-forme.
