Description

一种终端、拍摄方法及存储介质 技术领域
本公开涉及但不限于通信领域，具体而言，涉及一种终端、拍摄方法及存储介质。
背景技术
目前的双摄像头智能手机拍摄方法丰富了手机拍摄的功能，提高了拍摄画面的质量。但双摄像头拍摄方法依然存在一些缺陷：由于相关技术中终端上的两个摄像头位置和角度是固定不变的，而拍摄焦点通常并非是在取景画面正中心(在相机中轴线附近)，因此拍摄焦点中心的光线通常是通过侧面进入摄像头，随着焦点离相机中轴线偏差角度的增大，定位误差也会增大，容易导致画面变形。因此，目前的手机双摄拍照模式影响了拍摄的灵活度，也在一定程度上降低了拍摄画面的质量。
发明内容

具体实施方式
下文中将参考附图并结合实施例来详细说明本公开。需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互组合。
需要说明的是，本公开的说明书和权利要求书及上述附图中的术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。
实施例1
图1是本公开实施例的一种终端的结构框图。如图1所示，本公开实施例一提供了一种终端，可以包括：摄像头1，用于采集图像，其中，终端上包括至少两个摄像头1；存储有计算机程序的存储器2以及处理器3，处理器3被配置为运行计算机程序以执行：
确定拍摄信息，其中，拍摄信息包括：拍摄目标的位置或拍摄视角；
根据拍摄目标的位置调整终端所包括的至少两个摄像头的轴线方向以使至少两个摄像头聚焦于拍摄目标；或，根据拍摄视角调整至少两个摄像头的轴线方向的夹角；
控制被调整后的至少两个摄像头采集图像。
通过本公开的实施例，可以通过处理器控制终端上的摄像头的轴线方向，因此可以解决相关技术中终端摄像头拍照不灵活的问题，达到灵活拍照的效果。
需要说明的是，图3是根据本公开实施例的摄像头的轴线方向示意图，如图3所示，摄像头的轴线方向可以指摄像头的朝向，或者在摄像头的轴线所在的直线上，朝向被拍摄对象的方向。
需要说明的是，摄像头的轴线方向聚焦于拍摄目标，可以指摄像头的轴线方向相交于拍摄目标上。例如拍摄目标是一个物体，摄像头的轴线方向聚焦于拍摄目标可以指摄像头的轴线方向相交于该拍摄物体上。
现有智能手机使用空间位置固定且无法调整朝向的双摄像头结构，导致主要拍摄对象偏离摄像头轴线方向，容易造成画面变形；而本实施方式中提供的方案中摄像头的轴线方向聚焦于拍摄目标可以使拍摄对象始终处于摄像头主轴线附近范围，提高了摄像头的灵活性，避免了由于拍摄主体偏离摄像头主轴中心而导致的画面变形，提高了手机拍摄画面的质量。
在一实施方式中，处理器被配置为运行计算机程序以执行确定拍 摄信息，包括：
当拍摄信息中包括拍摄目标的位置时，确定拍摄信息包括：在确定拍摄目标之后，采集拍摄目标的图像并根据图像的场景深度信息确定拍摄目标的位置。
在一实施方式中，处理器被配置为运行计算机程序以执行根据拍摄目标的位置调整至少两个摄像头的轴线方向以使摄像头聚焦于拍摄目标，包括：
根据拍摄目标的位置确定至少两个摄像头在聚焦于拍摄目标时的目标轴线方向；
根据目标轴线方向和至少两个摄像头的当前轴线方向确定至少两个摄像头的轴线方向的调整角度；
按照调整角度将至少两个摄像头的当前轴线方向调整至目标轴线方向。
需要说明的是，例如，进入拍摄模式后，用户可以在屏幕上点击确定了拍摄目标(拍摄焦点)，摄像头通过检测镜头与拍摄目标的距离，根据内置算法可以计算出摄像头应该形成的角度，即可以确定至少两个摄像头在聚焦于拍摄目标时的目标轴线方向。
当拍摄信息中包括拍摄视角时，确定拍摄信息包括：
根据拍摄指令确定拍摄视角，其中，拍摄指令中指示了拍摄视角。
在一实施方式中，处理器被配置为运行计算机程序以执行根据拍摄视角调整至少两个摄像头的轴线方向的夹角，包括：
根据拍摄视角确定至少两个摄像头的轴线方向的目标夹角；
根据目标夹角和至少两个摄像头的轴线方向的当前夹角确定至少两个摄像头的轴线方向的调整角度；
按照调整角度将至少两个摄像头的当前轴线方向调整至目标轴线方向，其中，目标轴线方向的夹角为目标夹角。
在一实施方式中，处理器被配置为运行计算机程序以执行按照调 整角度将摄像头的当前轴线方向调整至目标轴线方向，其中，目标轴线方向的夹角为目标夹角，包括：
在预定时间内，调节至少两个摄像头的轴线方向的夹角在当前夹角和目标夹角之间的角度范围内连续变化。
需要说明的是，例如，用户在终端显示屏上选择了摄像头组中的两个摄像头的轴线方向夹角为50°，则终端可以根据用户的选择生成的指令指示终端所包括的至少两个摄像头的轴线方向夹角需要设置成50°，处理器根据该指令将两个摄像头的轴线方向夹角调整至50°。又如，用户选择了全景模式，则处理器可以根据指示了全景模式的指令按照预先设置的角度调整至少两个摄像头的轴线方向夹角。例如，预先设置全景模式的最大夹角是270°，当前终端上的两个摄像头的夹角是60°，则处理器控制两个摄像头的轴线方向调整至夹角为270°的状态。
需要说明的是，在预定时间内，调节至少两个摄像头的轴线方向的夹角在当前夹角和目标夹角之间的角度范围内连续变化并不限定夹角一定要在一个连续不间断的角度范围内连续变化，例如，可以是在0°到60°角度范围内变化，也可以是在全景模式中，在预定的时间内，摄像头的轴线方向的夹角由60°连续变至0°，再由0°连续变至270°，即也可以是在间断的角度范围内连续变化。
另外，调节至少两个摄像头的轴线方向的夹角在当前夹角和目标夹角之间的角度范围内连续变化也并不限定角度的变化在预定时间内一定是按照时间均匀变化的，例如可以是每1s的时间夹角均匀增加5°，也可以是前1s的时间夹角均匀增加5°，紧接着的下1s时间内夹角均匀增加了10°，也可以是夹角增加5°之后，暂停，待摄像头拍摄图像后，继续增大摄像头轴线方向的夹角。
在一实施方式中，处理器还被配置为运行计算机程序以执行：
在接收到合成指令后，合成通过至少两个摄像头采集到的图像得到合成图像。
在一实施方式中，处理器还被配置为运行计算机程序以执行合成通过至少两个摄像头采集到的图像得到合成图像，包括：
确定至少两个摄像头所采集的图像中的像素的深度值；
基于像素的深度值根据图像处理模式合成通过至少两个摄像头采集到的图像得到合成图像。
在一实施方式中，处理器还被配置为运行计算机程序以执行：向终端的显示屏输出通过摄像头组采集到的图像和/或合成图像。
在一实施方式中，摄像头组设置在终端的第一侧面上，其中，第一侧面可以为终端的一个侧面、终端的组成部分的一个侧面或者终端的组成部分的侧面所构成的组合侧面。
需要说明的是，上述的终端的一个侧面可以是终端或终端的组成部分的上侧面、下侧面、左侧面、右侧面、前侧面、后侧面等，第一侧面可以是终端上的任一侧面或终端的组成部分的任一侧面所构成的组合侧面。
在一实施方式中，第一侧面可以包括以下之一：
终端可以包括一个终端本体，其中，第一侧面为终端本体上的一个侧面；或者
终端可以包括互相连接的第一本体和第二本体，其中，第一侧面为终端在平直展开的状态下，位于第一本体和第二本体同一侧的侧面所形成的组合侧面；或者
终端可以包括互相连接的第一本体和第二本体，其中，第一侧面为第一本体上的一个侧面或第二本体上的一个侧面。
需要说明的是，上述的第一侧面可以是只包括了一个本体的终端上的一个侧面，也可以是包括了具有两个组成部分的终端(例如折叠手机、翻盖手机等终端)在平直展开的状态下，位于两个组成部分上的同一侧的侧面所构成一个组合的平面，即，第一侧面可以是这种组合而来的平面。
在一实施方式中，摄像头组中的摄像头分散分布在第一侧面的边缘。
需要说明的是，目前的手机双摄像头的两个镜头之间的基线(两个镜头的间距)很短，一般为10mm左右，而人类双眼的基线均值是64mm，相比之下目前的双摄手机基线太短，因此，在定位与图像处理过程中会引起较大的计算误差，只能计算较近物体的景深(浅景深)，在拍摄场景上具有较大的局限性。在本申请的一个实施方式中，摄像头可以分散分布在第一侧面的边缘，其中，分散分布在第一侧面的边缘可以指摄像头之间至少在工作状态下(例如拍照时)是分散分布的(并非是挨靠在一起)，并且分布在靠近第一侧面边缘的位置处，这样可以有效增加摄像头之间的基线长度，提高了图像深度的计算精度，增大可拍摄画面景深处理的有效范围，为用户带来更高的便捷性与实用性，有效提升用户体验。
例如图4所示，图4是根据本公开实施例的摄像头的位置示意图，其中，A部分可以表示终端的正面或者背面，图4中的B部分可以表示终端的上、下、左、右任一个侧面，在本实施例的摄像头组含有两个摄像头的情况下，两个摄像头可以是设置在终端的正面或背面上的1-2位置处，也可以是4-5、3-6、7-8、9-10位置处，也可以是1-8、2-7、4-9、5-10位置处，也可以是8-10、7-9、2-4、1-5位置处，当该两个摄像头设置在终端的上、下、左、右任一个侧面上时，可以设置在11-12位置处。
当终端上有多个摄像头，例如4个摄像头的时候，摄像头的位置可以按照正方形分布，例如，可以设置在1-10位置中可以构成正方形的四个位置上，如图4所示，可以是7-8-9-10、1-2-4-5、7-2-9-4、1-8-10-5，也可以是在水平方向和垂直方向上各设置两个摄像头，例如可以是1-5-3-6、2-4-3-6、7-9-3-6、8-10-3-6。
在一实施方式中，第一侧面为终端上的显示屏所在的侧面或终端上背离显示屏一侧的侧面。
需要说明的是，摄像头位于显示屏一侧可以方便拍摄者进行自拍，并且不影响拍摄者查看拍摄画面；摄像头设置在背离显示屏的一侧可以方便使用者查看被拍摄的画面。
在一实施方式中，终端上包括调整部件，该调整部件用于调整终端上的摄像头的轴线方向。
在一实施方式中，调整部件可以包括弯折结构，其中，弯折结构与摄像头连接，弯折结构用于直接调整摄像头的轴线方向；或者，弯折结构与承载摄像头的承载结构连接，弯折结构用于通过调整承载结构的弯折状态调整摄像头的轴线方向。
需要说明的是，弯折结构可以直接与摄像头本身的部件连接，用以直接带动摄像头轴线方向变化。例如，弯折结构可以是包括轴、铰链或联轴器等的可转动的结构，可以直接引起摄像头朝向变化，在这种情形下，终端本身可以保持原有的状态，不需要弯折。
在本公开的一个实施方式中，弯折结构可以与承载摄像头的承载结构连接，例如，承载摄像头的承载结构是终端的第一侧面上的一些结构，或者说是终端的第一侧面承载了摄像头，则，通过调整第一侧面的弯折状态就可以带来摄像头的轴线方向的变化。例如，弯折结构可以是折叠终端中间的合页或者铰链或者连接轴。当合页开合或者铰链、连接轴转动的时候，带动折叠终端的两个分体的开合，那么设置在分体上的摄像头的轴线方向就会发生变化。
又如，弯折结构可以是承托承载结构的一个结构，例如可弯折的板状构件，例如由多个小的板状构件相互连接所形成的可弯折的板状结构，可以通过控制小的板状构件的倾斜角度调整可弯折的板状结构整体的弯折状态。当弯折结构本身弯折时，可以带动承载结构的弯折。
再如，承载了摄像头的承载结构本身就可以是一个弯折结构，当弯折结构本身弯折时，相当于承载结构弯折。
在一实施方式中，在承载结构处于弯折状态时，摄像头分布在承载结构上的弯折轴线的两侧。
需要说明的是，承载摄像头的结构可以是终端上的第一侧面。当承载结构发生弯折时，即从平面状态变为曲面状态时，弯折线可以是在承载结构弯折后，将承载结构划分为多个弯折区域的边界线，其中，在承载结构发生弯折变化时，垂直于这些弯折区域表面的直线的方向也会发生变化。例如，某个平面(承载结构)左右两侧同时向上弯曲，形成剖面类似于与U型的结构，则该U型结构底部的线就可以理解为是弯折线，左右两侧弯曲的部分可以理解为被弯折线区分开的两个弯折区域；又如，某个平面(承载结构)弯折后形成了剖面为半圆弧线的曲面，则该曲面上所有垂直于该半圆弧线的直线(即该曲面上平行于该半圆筒状结构的轴线的直线)都可以理解为弯折线，该弯折线两侧的区域内，垂直于区域表面的直线的方向在承载结构弯折过程中都发生了变化。
需要说明的是，当摄像头组中的摄像头分布在承载结构上的弯折轴线的两侧时，由于垂直于弯折线两侧的弯折区域表面的直线的方向会在承载结构弯折时发生变化，这样就赋予了设置在承载结构上的摄像头组中的摄像头更多的朝向可能，例如摄像头的轴线方向可以在承载结构弯折后相交于拍摄目标处，使得终端可针对拍摄对象同时进行多角度拍摄，进一步使得终端能够适应多种拍摄场景，提升了拍摄的灵活性。

具体实施方式一
为了更好的理解本公开的实施例，以下结合场景对本公开实施例进一步说明。
本公开实施例通过在柔性屏/折叠屏智能手机同侧的两端分别安装一个摄像头实现双摄像头立体拍摄效果。在拍照时根据拍摄画面的对焦点自动调节手机的弯曲/折叠角度，使两个摄像头同时对准对焦点，同时采集拍摄两个摄像头的视觉图像和深度图像，进行图像处理，实现模拟人眼模式的3D立体照片拍摄和三维立体动态画面的拍摄。
在本公开的一个实施例中，通过柔性屏手机的弯曲带动手机两端的摄像头进行转动，来模拟人眼在观察事物时的眼球运动，模拟人眼的立体视觉，通过增大两摄像头的距离提高立体效果照片的拍摄范围，同时提出一种三维立体动态照片的拍摄方法。
一方面，相比于现有智能手机位置固定的双摄像头结构，两摄像头的相对位置关系不会随对焦点的位置而变化，在主要拍摄对象偏离画面中心的情况下容易导致画面变形问题的特点；本公开中的手机双摄像头可以根据拍摄对象的位置变化而自动调整手机弯曲度，来调整摄像头位置，使拍摄对象始终处于摄像头主轴线附近范围，提高了摄像头的灵活性，避免了由于拍摄主体偏离摄像头主轴中心而导致的画面变形，提高了手机拍摄画面的质量。
另一方面，针对现有双摄智能手机的两个摄像头间距短，导致的计算误差较大，只能计算较近物体的景深的问题，本公开中的柔性屏/折叠屏手机两个摄像头间距采用模拟人眼视角的较大间距。
除此之外，本公开的实施例可以利用柔性屏/折叠屏手机的两摄像头的较大视差近距离拍摄三维立体动态图片，生成在一定角度内可以旋转查看的三维场景照片，提升了照片的真实性和拍照的趣味性。
图5a至图6b针对柔性终端和折叠终端的结构、拍摄状态等提供了示意，如图5a至图6b所示，该柔性屏/折叠屏智能手机的屏幕具有可弯折的特点，两个摄像头分别安装在手机背面的不同位置。其中在柔性屏手机中，如图5b所示，第一摄像头安装在上半部分、第二摄像 头在下半部分，两个摄像头在同一条竖直线上，由于柔性屏手机或柔性终端具有可弯折性，因此两个摄像头的相对位置会随手机屏幕的弯曲而发生改变，弯折过程示意如图5c、图5d。在折叠屏手机中，两摄像头分别安装在折叠屏手机左右屏幕的两侧的顶部位置，摄像头位置随屏幕的折叠运动而发生变化，如图5e。柔性屏手机屏幕弯折的方式不只局限于两侧同步弯折或者弯曲程度相同，柔性屏幕各个部位的弯曲程度会随预设模式的不同和拍摄场景条件的变化而有所不同，通过指令自动调整。
图6a和图6b是折叠手机的结构示意图，其中，两个摄像头设置在折叠手机的背面的左上角和右上角，折叠屏手机的折叠方式也会随着拍摄场景条件的差异而采取不同的折叠机制。例如，以图6a所示的折叠终端的背面为例，以A屏为参照基准折叠B屏，以B屏为参照基准折叠A屏，AB屏同步折叠，AB屏不同步折叠转动等折叠方式。
本公开实施例主要涉及一种柔性屏/折叠屏终端的拍摄方法和柔性屏/折叠屏移动终端，在柔性屏/折叠屏手机的背面的不同位置分别安装一个摄像头。拍摄时设置对焦点，两个摄像头进行分别取景并实时计算画面中的场景深度；根据对焦点与手机摄像头的距离自动实时调节柔性屏/折叠屏各部分的弯曲程度，将两个摄像头对准画面焦点；第一摄像头和第二摄像头同时拍摄，获得拍摄画面并获得拍摄场景的深度值；根据预设的图像处理模式对图片进行图像处理。实现模拟人眼模式的立体效果照片拍摄和三维立体动态照片的拍摄。
拍摄过程原理示意图如图7所示，图7是根据本公开可选实施例的移动终端拍摄方法的流程图，由于柔性屏/折叠屏手机的第一摄像头与第二摄像头模拟人眼立体视觉模式，摄像头间距较大，较大的视差可以支持较大范围内的场景深度值计算，可以支持较远距离的立体拍摄效果处理。同时通过控制屏幕调整摄像头拍摄角度，可以将摄像头主光轴对准拍摄焦点，使拍摄对象的成像区域在摄像头主轴附近范围内，避免了拍摄主体偏离画面中心造成的画面变形，提高了画面质量。
当拍摄物体距离摄像头较远时(最大立体图像拍摄范围内)，可以进行立体效果照片的拍摄，如背景虚化、多重对焦等立体效果的处理；当近距离拍摄时支持三维立体动态照片的拍摄：由于两摄像头拍摄角度差较大，此时可以支持三维动态图像的采集，计算拍摄场景的深度图，对拍摄范围内的场景进行三维重建，并生成一定角度内可以转动查看的三维动态图片。
具体的拍摄实现过程如图7所示。启动柔性屏/折叠屏双摄像头拍摄模式；检测屏幕当前的弯曲/折叠角度及两摄像头所处的位置关系，并显示两摄像头所拍摄的预览画面；相机自动对焦或用户手动设置对焦点；检测对焦点与柔性屏/折叠屏手机的距离，根据对焦点与摄像头一及摄像头二的位置关系，计算拍摄时屏幕应该弯曲/折叠的角度参数；通过硬件传感器获得手机屏幕当前的弯曲/折叠角度；判断屏幕当前角度与拍摄角度参数是否一致；若一致则直接拍摄画面；若不一致，则计算补偿参数，发出指令，屏幕自动弯曲/折叠至指定的角度，然后进行画面拍摄。
本拍摄方法具有多种应用场景，其中典型的三个应用场景是：较远距离拍摄具有立体效果的照片、近距离拍摄三维立体动态照片，以及自动拍摄全景照片模式。
拍摄具有立体效果照片的实现流程如图8所示，图8是本公开可选实施例的移动终端拍摄立体效果照片的流程图。相机自动对焦或用户手动设置对焦点；第一摄像头、第二摄像头分别取景，分别获得实时预览图像第一预览图像与第二预览图像，并实时计算画面中的场景深度；根据对焦点所在位置与第一摄像头及第二摄像头的位置关系，根据预设算法计算出手机柔性屏/折叠屏需要弯曲/折叠的角度；发出弯曲指令，调节柔性屏各部分的弯曲程度，使得屏幕弯曲/折叠到指令所示形状，使两个摄像头同时对准对焦点；第一摄像头、第二摄像头进行重新对焦，并拍摄照片，获得第一图像与第二图像；根据第一图像与第二图像计算出拍摄场景的深度图，获取拍摄场景每个像素的深度 值；根据拍摄场景的深度值与拍摄画面，选择图片处理模式，根据预设的图像处理算法对图片进行图像处理；输出图片。
拍摄三维立体动态照片拍摄流程的实现流程如图9所示，图9是本公开可选实施例的移动终端拍摄三维动态图片的流程图。选择三维立体动图拍摄模式，进行自动对焦，可手动辅助对焦；第一摄像头、第二摄像头分别取景，获得实时预览图像；根据预览图像实时计算画面中的场景深度，根据对焦点位置，自动调节柔性屏/折叠屏的弯曲参数，将两个摄像头对准对焦点；检测两摄像头位置是否水平平齐，并对用户进行相应的指导提示；第一摄像头和第二摄像头同时拍摄，获得第一图像与第二图像；计算拍摄场景的深度图，进行场景的三维重建，将色彩图像像素点与重建场景相对应，对两摄像头中间视角的图像进行过渡处理；进行画面合成，输出一定角度内可旋转观察的三维立体场景照片。
自动拍摄全景照片模式的实现流程如图10所示，图10是本公开可选实施例的移动终端自动拍摄全景照片的流程图，拍摄时终端的状态如图11所示，图11是本公开可选实施例的移动终端自动拍摄全景照片的状态示意图。选择自动拍摄全景图片模式；第一摄像头、第二摄像头分别取景，获得实时预览图像；通过硬件传感器获得手机屏幕当前的弯曲/折叠角度及机身状态；判断当前手机屏幕是否平直(未弯曲/折叠)，若机身屏幕为非平直状态，则向屏幕角度控制器发出指令，控制手机屏幕恢复平直状态，否则进如下一步；判断当前机身状态是否为横向放置，若机身未处于横向位置状态，则通过界面提示用户将手机横向放置，使两摄像头处于水平位置，否则进入下一步；根据预设模式，屏幕两端同时向内侧弯曲带动摄像头转动，两摄像头实时采集若干拍摄画面，直至达到最大预设拍摄角度(或用户手动终止拍摄)；根据预设算法将采集到的若干图像合成一张全景照片，输出全景照片。
在用户界面中，“A+B”按钮功能为分屏同时显示两个摄像头拍摄画面，用户界面如图12a所示；“A/B”按钮功能为全屏显示单个摄 像头画面，用户界面如图12b所示；“合成”按钮功能为根据所选的拍摄模式，合成两个摄像头所拍摄的画面，用户界面如图12c所示。拍摄过程中，可以隐藏界面工具栏，提高视觉体验，如图12d所示；拍摄立体效果照片时，用户界面如图12e至12g所示，其中图12e是本公开可选实施例的终端的拍摄立体动图-分屏显示的界面示意图、图12f本公开可选实施例的终端的拍摄立体动图-单摄像头画面的界面示意图、图12g是根据本公开可选实施例的终端的拍摄立体动图-合成画面查看界面的界面示意图；在完成立体动图的拍摄后，可以通过在屏幕上左右横向滑动，在一定角度范围内查看立体照片的不同角度拍摄场景。
拍摄全景照片时，用户界面操作如图12h所示。图12h是本公开可选实施例的终端的自动拍摄全景照片的界面示意图。
通过本公开的实施例，通过柔性屏实现摄像头随屏幕转动，模拟了人演的立体视觉原理。模拟了人眼球随所观察物体移动的特点，相比现有相机可减少拍摄主体的画面变形，提高画面质量；增大了两摄像头之间的距离来模拟人眼的双眼视差，可以提高拍摄场景深度的测量精度，拍摄立体图片的立体效果更强，同时也增大了立体图片的拍摄距离。可以近距离利用双摄像头的较大拍摄视差，来拍摄、合成立体动态场景照片，实现在一定角度内的三维场景查看。实现双摄像头自动拍摄全景照片，避免了手动转动手机造成的画面质量不稳定的问题，两摄像头分别向左右两侧同时拍摄提高了拍摄效率。
显然，本领域的技术人员应该明白，上述的本公开的各模块或各步骤可以用通用的计算装置来实现，它们可以集中在单个的计算装置上，或者分布在多个计算装置所组成的网络上，在一实施方式中，它们可以用计算装置可执行的程序代码来实现，从而，可以将它们存储在存储装置中由计算装置来执行，并且在某些情况下，可以以不同于此处的顺序执行所示出或描述的步骤，或者将它们分别制作成各个集成电路模块，或者将它们中的多个模块或步骤制作成单个集成电路模块来实现。这样，本公开不限制于任何特定的硬件和软件结合。
以上仅为本公开的优选实施例而已，并不用于限制本公开，对于本领域的技术人员来说，本公开可以有各种更改和变化。凡在本公开的原则之内，所作的任何修改、等同替换、改进等，均应包含在本公开的保护范围之内。
