Description

一种摄像头组件和移动设备 技术领域
本发明涉及通信技术及图像采集领域, 尤其涉及一种摄像头组件和移动设 备。
背景技术
随着通信事业的发展, 智能移动设备逐渐进入人们的生活, 移动设备中的 摄像头逐渐由现在的拍照功能转变为场景的实时传输, 为了使移动设备使用更 加方便、 更加灵活, 双摄像头几乎是现阶段各种智能移动设备的必备配置。
但是, 目前大多数智能移动设备中的摄像头存在的主要问题是:
1、 介于成本、 构造等技术问题, 移动设备的后置摄像头像素较高, 前置摄 像头的像素较低;
2、 目前, 摄像头的变焦主要有两种: 一种是数码变焦, 另一种是光学变焦, 数码变焦采用差值算法, 在感光元件的像素数不变的前提下, 通过对两个相邻 像素进行插值运算, 凭空算出来一个数码像素, 由于该像素是算出来的, 与实 际有一些误差。 因此, 数码变焦只能把图像放大, 实际上画质并没有本质提高, 而且降低了摄像头拍摄的最大像素; 光学变焦是真正意义上的变焦, 通过镜片 的移动来放大或者缩小需要拍摄的景物, 但是, 随着移动设备越做越薄, 光学 变焦在移动设备上实现起来, 成本非常大、 难度非常高。
为了解决问题 1,现有技术中公开了一种可 360°旋转手机摄像头,该可 360° 旋转手机摄像头包括手机和设置于手机上的摄像头, 所述的手机上设置有安装 摄像头的摄像头安装体, 摄像头安装体与手机本体为分体式, 并通过中心旋转 轴连接, 摄像头数据线位于旋转轴内, 通过旋转轴与手机本体的数据处理系统 相接。 现有技术虽然可以解决现有手机前后两个摄像头像素不一致造成的使用 不便的问题; 但是, 该技术中摄像头安装体与手机本体为分体式, 并通过中心 旋转轴连接, 这使得手机的结构复杂, 体积较大, 而且设置在手机的外部容易 磕碰, 不利于摄像头镜头的保护。
针对问题 2, 现有技术中提出一种将镜头从手机上突出来的光学变焦手机, 这种手机虽然可以实现光学变焦, 但是成本较大, 改变了手机的传统外观而且 非常容易磨损甚至被磕掉, 安全性和耐久度太低, 还会使用户使用手机时的感 觉变差。
