The utility model relates to a focus digital camera camera, which includes a lens seat and a lens tube set in the lens seat. The lens barrel is used to fix the lens lens. The lens seat can move along the inner wall of the lens tube. The inner wall of the lens seat is provided with a front oil cavity and a rear oil cavity. The outer wall of the lens barrel is connected with a double head piston. The head piston is matched with the front oil cavity and the rear oil chamber; the front oil cavity and the rear oil cavity are connected to the front and rear cavity of the oil cavity by independent oil channels. The front and rear chambers of the oil chamber are separated by the intermediate piston; the intermediate piston is connected with the screw adjusting seat and the threaded joint is used to drive the intermediate piston movement. The camera uses hydraulic transmission to focus on the focus, the structure is simple, the occupancy is small, and the processing precision is low, and it has a long service life. Because of the hydraulic transmission, the stability is good. One

一种调焦数码相机摄像头
本技术涉及一种调焦数码相机摄像头,属于光学镜头
技术介绍
随着多媒体技术的发展,数码相机、摄影机越来越为广大消费者青睐,在人们对数码相机、摄影机追求小型化的同时,人们希望于同一位置可拍摄远近距离不同物体的影像,且获得的影像画面清晰,由此变焦相机应运而生,而相机的变焦是通过相机内的摄像头的镜头的移动来实现。一般而言,数码相机镜头的变焦方式分为数字变焦与光学变焦两种。数字变焦是利用影像传感器的电荷耦合器(ChargeCoupledDevice,下称CCD)局部成像,即于原来拍摄的照片中挖出一块放大,数码相机虽可通过插值等方式在一定程度上改善成像质量,最后对照片成像质量仍会有一定影响。故数字变焦是以牺牲分辨率与图像质量为代价的变焦。数码相机的光学变焦是依靠光学镜头结构实现变焦,即通过改变变焦镜头的各镜片的相对位置,从而改变镜头的焦距使被拍摄的景物放大或缩小,光学变焦倍数越大,其越能拍摄较远景物。由此,人们通常通过光学变焦实现数码相机镜头的变焦。现有技术的摄像头镜头模组均是通过齿轮或螺纹结构来实现调焦,存在的缺点是结构较复杂,体积大;另外,为保证调焦精度,上述结构对加工精度要求较高,且容易损坏。
