Description

一种移动终端 技术领域
本发明涉及电子技术领域，尤其涉及一种移动终端。
背景技术
随着电子信息技术和光学技术的飞速发展，移动终端(例如手机)在日常生活中扮演者越来越重要的角色，因此，用户对手机的功能和外形的需求也更加突出，尤其是手机的拍照性能。
而变焦技术是衡量手机的拍照性能优劣的重要标准之一。变焦技术可以分为数码变焦(Digital Zoom)和光学变焦(Optical Zoom)，其中，数码变焦易于实现，它实际上可以看做是画面的电子放大，将原来CCD(Charge-coupled Device，电荷耦合元件)影像感应器上的一部份像素使用插值处理手段进行放大，因此，通过数码变焦，拍摄的景物放大了，但它的清晰度却会下降。
而光学变焦是依靠光学镜头结构来实现变焦的，通过镜头的镜片移动来放大与缩小需要拍摄的景物，光学变焦倍数越大，能拍摄的景物就越远，而且清晰度不仅不会受到影响反而可以得到提高。然而，由于光学变焦是依靠光学镜头结构来实现变焦的，因此，使用光学变焦技术实现拍照功能的手机的厚度和重量都比较大，不易携带，另外，由于光学变焦的功能是通过镜头的伸缩来实现，整个镜头模组的尺寸比较大，容易损坏。

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。
为便于理解本发明实施例提供的一种移动终端，首先介绍与本发明相关的一些概念。
数码变焦，是通过移动终端内的处理器，把图片内的每个像素面积增大，从而达到放大图片的目的。即使用图像处理软件把图片的面积变大，把原来CCD影像感应器上的一部份像素使用″插值″处理手段做放大，将CCD影像感应器上的像素用插值算法将画面放大到整个画面。由于数码变焦是在感光器件垂直方向上的变化达到变焦效果的，在感光器件上的面积越小，视觉上就会让用户只看见景物的局部，但是由于真正的焦距并没有变化，所以，图像质量相对于正常情况下较差。
光学变焦，是依靠光学镜头结构来实现变焦。它是通过镜头、物体和焦点三方的位置发生变化而产生的，当成像面在水平方向运动的时候，视觉和焦距就会发生变化，更远的景物变得更清晰，让人感觉像物体递进的感觉。光学变焦正是利用镜头内透镜的移动来改变焦距，从而实现图像的放大与缩小。由于这种图像的放大与缩小是通过物理学原理，在放大与缩小的过程中，感光元件从被摄体中直接感光并形成影像，而没有经过其他任何的电子放大处理。并且在放大与缩小的过程中，感光元件都是全幅面成像，图象能够保持原有的最高分辨率。因此，通过光学变焦所获得的图像不但使被 摄物体变大了，同时也相对更加清晰。
另外，本发明实施例提供的移动终端，可以是如手机或者I-PAD等。为方便理解，以下实施例以手机为例进行描述，其中，所述手机可以为智能手机(Smart phone)或者非智能手机(Feature phone)，本发明对此并不作限制。
本发明的实施例提供一种手机，所述手机包括手机外壳，如图1所示，所述手机还包括潜望式光学变焦镜头01和位于手机外壳上的显示屏02，其中，
所述潜望式光学变焦镜头01与所述显示屏02在厚度方向上不重叠排布，且所述潜望式光学变焦镜头01位于所述手机的顶部区域潜望式光学变焦镜头，如图1a所示，为以图1为参考，所述潜望式光学变焦镜头01与所述显示屏02的空间排布的左视图，所述潜望式光学变焦镜头01与所述显示屏02在厚度方向上不重叠排布，这样一来可以充分降低潜望式光学变焦镜头01的体积对手机厚度的影响。
具体的，所述潜望式光学变焦镜头01，用于用于通过光学变焦采集光信号形式的图像，以使得光电转换芯片将所述光信号形式的图像转换为数字信号形式的图像；所述显示屏02，用于显示所述数字信号形式的图像。
光学变焦系统的类型按照光学结构特征的不同划分有很多种类。其中，按照伸缩和光学结构方式，可以将潜望式光学变焦镜头01分为直筒式潜望式光学变焦镜头01和潜望式光学变焦镜头01。
直筒式光学变焦镜头利用一节节套筒的伸缩，来进行焦长的调整，达到广角或是望远的取景、拍摄效果，其光学特征是：变焦时，镜头的光轴始终与焦平面垂盲。由于直筒式光学变焦镜头的光轴和焦平面呈90度，因此，在进行长焦拍摄时，手机的厚度较厚，这也成了手机小型化设计的瓶颈。同时长长的伸出镜头，也可能受到意外外力的作用导致损坏。
本发明实施例中采用的是潜望式光学变焦镜头01，所述潜望式 光学变焦镜头01俗称内变焦镜头，也可以称为折叠光学镜头，由于光学变焦是在机身内部完成，所以潜望式光学变焦镜头01可以很容易安装滤镜，无需再额外安装镜头筒。另外，由于潜望式光学变焦镜筒长度是固定不变的，且镜头小巧，因此可以非常方便地进行密封处理，所以密封性好。所述滤镜可位于所述手机外壳上。
潜望式光学变焦镜头01里有两块平面镜(实用仪器中这两块平面镜可以被一块或者两块三棱镜替代)放在45度的斜面上，如图2所示，其中，1为潜望式光学变焦镜头01的上反射镜，6为潜望式光学变焦镜头01的下反射镜，2、3、4、5为潜望式光学变焦镜头01的成像透镜组，7为观察孔，这样一来，潜望式光学变焦镜头01上端景物的光线沿直线传播，当光线遇到平面镜时就会被反射，再经过成像透镜组2、3、4、5，最后反射到观察孔7，以使得潜望式光学变焦镜头01采集到的光信号形式的图像通过观察孔7输出，可以看出，潜望式光学变焦镜头01的光学特征是：镜头的光轴与焦平面平行，经过棱镜折射后的光线光轴与焦平面垂直，利用这样的光学特征制造的镜头可以明显缩小镜头的厚度。
进一步地，可以将感光元件(如CCD、CMOS等)置于观察孔7之后，以便将潜望式光学变焦镜头01采集到的光信号形式的图像转换为数字信号形式的图像。
相应的，还可以在潜望式光学变焦镜头01内仅设有上反射镜1和成像透镜组2、3、4、5，这样一来，可以将将感光元件(如CCD、CMOS等)置于成像透镜5之后，以便将潜望式光学变焦镜头01采集到的光信号形式的图像转换为数字信号形式的图像。
本发明实施例提供的手机，正是利用了潜望式光学变焦镜头01成像质量高且厚度薄，体积轻巧的特点，将潜望式光学变焦镜头01内置于潜望式光学变焦镜头01手机内，通过重新排布所述手机内部的潜望式光学变焦镜头01与显示屏02的位置，保证所述潜望式光学变焦镜头01与所述显示屏02在同一厚度方上不重叠排布，减小了手机的厚度和重量，将手机的拍照性能和便携性有效的结合。
可选的，可以采用LCD(Liquid Crystal Display，液晶显示器)、OLED(Organic Light-Emitting Diode，有机发光二极管)等形式来配置所述显示屏02。进一步的，在本发明实施例提供的显示屏02内可以集成有触控功能，当显示屏02检测到在其上或附近的触摸操作后，传送给手机内的AP(Appellation Processor，应用处理器)以确定触摸事件的类型，随后AP根据触摸事件的类型在所述显示屏02上提供相应的视觉输出。
由于所述潜望式光学变焦镜头01与所述显示屏02在厚度方向上不重叠排布，且所述潜望式光学变焦镜头01置于所述手机的顶部区域，这样的空间布局会导致原本应该放在手机顶部区域中心位置的传统听筒(例如Reciver发声器)，需要偏置到距离该中心位置16毫米处的位置，无法通过手机入网认证的音频测试。
具体的，传统听筒是利用电磁感应现象使用动圈式器件制成的，当声波使金属膜片振动时，连接在膜片上的线圈(叫做音圈)随着一起振动，音圈在永久磁铁的磁场里振动，其中就产生感应电流(电信号)，感应电流的大小和方向都变化，变化的振幅和频率由声波决定，所述生感应电流经扩音器放大后传给扬声器，从扬声器中就发出放大的声音。然而，使用这种传统听筒时，需要将该传统听筒置于距所述中心位置8毫米以内的位置，才能使该传统听筒发出的声音达到所述音频测试的参数指标，因此，本发明的实施例使用压电发声器03和透明面板04解决上述问题。
如图3所示，所述手机还包括位于所述终端外壳上的压电发声器03，以及位于所述显示屏02、所述潜望式光学变焦镜头01和所述压电发声器03上的透明面板04，
所述显示屏02、所述潜望式光学变焦镜头01以及所述压电发声器03任意两者之间在厚度方向上不重叠排布；所述压电发声器03与所述玻璃面04板互相接触。
其中，所述压电发声器03，用于根据AP的触发信号产生声压，以引起所述透明面板产生震动；所述透明面板04，用于根据所述压 电发声器产生的声压震动。
具体的，可以使用OCA(Optically Clear Adhesive，光学透明胶)将所述透明面板04与所述显示屏02进行贴合，如图3a所示，为以图3为参考，所述潜望式光学变焦镜头01、所述显示屏02、所述压电发声器03以及所述透明面板04的空间排布的左视图。
示例性的，可以将所述压电发声器03与所述透明面板04贴合，当所述压电发声器03受控于AP输出的触发信号时，所述压电发声器03产生声压，所述透明面板04接收所述压电发声器03产生的声压，进而产生震动并发声。这样一来，无需使用传统听筒，而是通过压电发声器03与透明面板04的结合便可进行发声，而且，通过所述压电发声器03与所述透明面板04的结合产生振动进行发声的音效，完全可以通过手机入网认证的音频测试。
同时，由于所述压电发声器03与所述潜望式光学变焦镜头01和所述显示屏02在厚度方向上不重叠排布(如图3a所示)，这样的空间布局可以避免所述潜望式光学变焦镜头01影响手机的厚度。
示例性的，所述压电发声器03可以为压电陶瓷发声器。所述压电陶瓷发声器，是一种无铅的压电陶瓷发声元件，它主要由金属薄片与压电陶瓷薄片组成，其中，金属薄片表面上紧密贴合有2片或以上相同尺寸并依次紧密贴合的压电陶瓷薄片，相邻的压电陶瓷薄片的极化方向相反，这种新结构的压电发声器03所产生的声压与压电陶瓷薄片的数量成正比，数量越多，声压越大，通过增加压电陶瓷薄片数量，轻易地实现所需的大声压，其生产工艺简单，生产成本较低。
可选的，所述透明面板04，可以为玻璃面板或者蓝宝石面板等。其中，透明面板04与显示屏02配合完成触控输入和显示的作用。一种可能的实现方式如前所述，即在显示屏02上集成触控功能，以完成触控输入和显示功能；在另一种可能的实现方式中，可以在透明面板04上集成触控功能，以使得透明面板04与显示屏02集成为TP(Touch panel，触控面板)，完成手机的触控输入和显示功能。 其中，TP在功能上可以划分为感应器(Sensor)、控制器(Controller)及软件(Software)三部分。感应器即接收经接触所输入的讯息的部分，可以设置在透明面板上；控制器功能在于分析、计算接触点所在位置，并转换模拟信号为数位信号并传输至AP，可以由显示屏02内集成的电路完成，同时显示屏02还可以接收AP的输出命令进行显示；软件部分在连接AP与控制器问的沟通协定，让AP可以接收并辨认控制器所输入的数位信号以进行后续处理动作。
进一步地，如图4所示，所述移动终端还包括：与所述潜望式光学变焦镜头01分别相连的所述光电转换芯片05、马达驱动芯片06和光学防抖驱动芯片07，其中，
所述光电转换芯片05，用于将所述光学变焦镜头01采集的光信号形式的图像换为数字信号形式的图像；
所述马达驱动芯片06，用于调整所述潜望式光学变焦镜头01实现光学变焦；
所述光学防抖驱动芯片07，用于对所述潜望式光学变焦镜头01采集光信号形式的图像进行校正。
需要说明的是，所述潜望式光学变焦镜头01与所述光电转换芯片05、马达驱动芯片06、光学防抖驱动芯片07在厚度方向上不重叠排布，减小了手机的厚度和重量，将手机的拍照性能和便携性有效的结合。
具体的，所述光电转换芯片05中可以包含有感光元件，例如CCD(Charge-coupled Device，电荷耦合元件)或者CMOS(Complementary Metal Oxide Semiconductor，互补金属氧化物半导体)，两者的作用都是将光线转换为数字信号，然后该数字信号被传送到AP后进行输出。
进一步地，可以将所述光电转换芯片05承载于印刷电路板上，通过所述印刷电路板实现所述潜望式光学变焦镜头01与所述光电转换芯片05之间光电信号的传输过程；类似的，所述马达驱动芯片06和所述光学防抖驱动芯片07可以分别位于马达印刷电路板和光 学防抖印刷电路板上，分别实现所述潜望式光学变焦镜头01与所述马达驱动芯片06之间光电信号的传输过程，以及所述潜望式光学变焦镜头01与所述光学防抖驱动芯片07之间光电信号的传输过程。
进一步地，如图5所示，所述移动终端还包括：与所述压电发声器03、所述显示屏02、所述光电转换芯片05、所述马达驱动芯片06和所述光学防抖驱动芯片07均相连的AP08，其中，
所述AP08，用于获取所述光电转换芯片05潜望式光学变焦镜头输出的所述数字信号形式的图像，并将所述数字信号形式的图像输出至所述显示屏02；还用于生成触发信号指示所述压电发声器03产生声压；还用于生成第一控制信号指示所述马达驱动芯片06调整所述潜望式光学变焦镜头01实现光学变焦；以及生成第二控制信号指示所述光学防抖驱动芯片07对所述潜望式光学变焦镜头01采集光信号形式的图像进行校正。
另外，所述AP08内可以包含有图像处理器，即ISP(Image Signal Processing，图像信号处理)芯片，用于处理所述光电转换芯片05输出的所述数字信号形式的图像。
如图5所示，所述潜望式光学变焦镜头通过光学变焦采集光信号形式的图像，并传送至所述光电转换芯片05对所述图像进行图像处理，以将所述光信号形式的图像转换为数字信号形式的图像；同时配合所述马达驱动芯片06和所述光学防抖驱动芯片07，对所述潜望式光学变焦镜头进行变焦和校正，最终将所述数字信号形式的图像传送至AP08，以使得AP08中的ISP芯片进行数据处理，并通过所述显示屏02输出所述数字信号形式的图像，为用户呈现拍摄影像的视觉输出。同时，AP08还可以输出触发信号控制所述压电发声器03和透明面板进行发声04，当AP输出触发信号向压电发声器03指示发声时，所述压电发声器03产生声压，此时所述透明面板04根据所述压电发声器03产生的声压产生震动并发声。
至此，通过对手机中各个部件的合理空间布局，实现光学变焦下对图像的采集、光电转化并最终输出，将手机的拍照性能和便携 性有效的结合，提高用户体验。
进一步地，如图6所示，所述移动终端还包括：与所述AP08相连的闪光灯09，其中，
所述闪光灯09，用于为所述潜望式光学变焦镜头采集的图像增加曝光量。所述闪光灯09可以在很短时间内发出很强的光线，多用于光线较暗的场合瞬间照明，也用于光线较亮的场合给被拍摄对象局部补光。
