具体实施方式
下面通过具体实施方式结合附图对本发明作进一步详细说明。
很多设备都可实现对采集数据的图像显示。在本申请实施例中，图像包括图、图形和波形。波形包括数据随时间推移的趋势图。在对图像的分辨率进行调整时，分辨率调整指令由用户通过触摸屏输入，根据用户的触摸动作对用户期望的图像的分辨率进行调整，并按照调整后的分辨率显示数据。下面以医学临床监护设备显示的趋势图为例进行说明，本领域技术人员应当理解，本申请的分辨率调整方案同样可适用于其它医疗设备或图像显示设备。例如应用于中央站、除颤仪、麻醉机的不同分辨率的调整，如参数、波形、压缩波形、影像数据的不同分辨率的调整等。
实施例一：
在一种具体实例中，监护设备的结构如图3所示，包括趋势图分辨率调整装置10、数据检测装置20、数据处理模块30和触摸屏40。数据检测装置20用于检测被监护者的生命体征参数，例如用于检测患者的血压、心率、血氧等生命体征参数。数据处理模块30的输入端耦合到数据检测装置20的输出端，用于接收数据检测装置20检测的生命体征参数，对生命体征参数进行分析处理，生成可视化显示数据。触摸屏40为多点触摸显示屏，其与数据处理模块30信号连接，用于为监护设备提供生命体征参数的可视化趋势图显示和用户输入接口，在感应到用户的操作时输出触摸信息。趋势图分辨率调整装置10分别与触摸屏40和数据处理模块30信号连接，接收触摸屏40输出的触摸信息，对用户选择的趋势图进行分辨率调整，并向数据处理模块30输出按调整后分辨率显示的结果。
在一具体实例中，趋势图分辨率调整装置10的结构示意图如图4所示，包括动作识别单元110、调整判断单元120、分辨率计算单元130和显示单元140。
动作识别单元110用于接收触摸屏输出的触摸信息，根据触摸信息识别用户触摸操作的动作，生成动作信息。
调整判断单元120用于判断动作识别单元110检测到的触摸动作是否符合预定的分辨率调整条件。调整判断单元120判断的一种具体方式是判断检测到的触摸动作是否与预定的分辨率调整动作相对应，根据判断结果确定触摸动作是否符合预定的分辨率调整条件。调整判断单元120还可根据动作信息中触摸操作的位置信息进行辅助判断，即判断触摸动作是否位于某个趋势图的显示区域；如果触摸动作不在任一趋势图的显示区域内，则认为触摸动作不符合预定的分辨率调整条件；如果触摸动作在某一趋势图的显示区域内，则将触摸操作的该趋势图作为用户期望调整的趋势图。
分辨率计算单元130用于在调整判断单元120判断触摸动作符合预定的分辨率调整条件时，根据动作识别单元110生成的动作信息和预设的计算方法计算调整后的趋势图显示的分辨率。如果预定的分辨率调整动作是多个触点的滑动，则分辨率计算单元的一种结构可如图5所示，包括初始几何量计算子单元131、移动后几何量计算子单元132和分辨率计算子单元133。初始几何量计算子单元131用于根据动作信息中多个触点初始接触触摸屏时的位置信息计算多个触点的初始几何量；移动后几何量计算子单元132用于根据动作信息中该多个触点最终的位置信息计算多个触点的滑动后几何量，当多个触点的位置信息保持不变持续设定时间后，认为此时的位置信息为多个触点的最终的位置信息，或当检测到多个触点离开触摸屏后，将最后检测到的多个触点的位置信息作为最终位置信息；分辨率计算子单元133用于根据计算公式计算调整后的分辨率，例如利用初始几何量和移动后几何量的比值与调整前后分辨率的比值相等的关系计算调整后分辨率。
显示单元140用于根据分辨率计算单元130输出的调整后分辨率将界面上用户期望调整的趋势图按调整后的分辨率显示数据，并在调整判断单元120检测到的触摸动作不符合预定的分辨率调整条件时，使界面上的趋势图维持原分辨率。
基于上述监护设备，其对趋势图分辨率进行调整的流程如图6所示，包括以下步骤：
步骤210，将监护仪的趋势图界面处于打开状态，按当前分辨率显示病人的趋势数据。
步骤220，检测触摸操作。当用户期望调整界面的分辨率时，用户和触摸屏接触，执行触摸操作以改变为用户期望的显示分辨率，该步骤为用户和监护仪的交互过程。当用户接触触摸屏，***开始响应用户的触摸操作，该步骤根据用户和触摸屏的接触生成各种触摸相关的信息，触摸信息主要为触摸点的相关信息，包括但不限于触摸点坐标、触摸的时间和/或触摸点的压力。动作识别单元在显示趋势图的界面状态下检测用户通过触摸屏输入的触摸操作，生成触摸信息。
步骤230，识别触摸动作。触摸点的触摸信息是关于单个触摸点的信息而非动作信息，需要根据触摸点信息识别出用户的动作，生成用户触摸动作信息，动作信息包括但不限于动作、动作方向、动作速度（大小和方向）和/或动作的加速度（大小和方向）。
步骤240，判断检测到的触摸动作是否符合预定的分辨率调整条件，如果是，则执行步骤250，否则执行步骤210，界面上的趋势图维持原分辨率。要对趋势图的分辨率进行调整，需要满足两个条件，一个是需要知道对哪个趋势图进行调整，这可以通过默认设置或用户选择确定。另一个是需要判断检测到的触摸动作是否与预定的分辨率调整动作相对应。当需要调整的趋势图通过默认设置可确定时，只需要判断检测到的触摸动作是否与预定的分辨率调整动作相对应，根据判断结果确定触摸动作是否符合预定的分辨率调整条件，当触摸动作与预定的分辨率调整动作相对应时，认为符合预定的分辨率调整条件，允许对默认的趋势图的分辨率进行调整。当触摸动作与预定的分辨率调整动作不相对应时，认为不符合预定的分辨率调整条件，禁止对趋势图的分辨率进行调整。当需要调整的趋势图通过用户选择确定时，判断检测到的触摸动作是否符合预定的分辨率调整条件的步骤包括：
确定期望调整的趋势图步骤，根据触摸操作的位置信息判断触摸动作是否位于趋势图的显示区域，如果触摸动作的位置坐标不在趋势图的显示区域内，则认为触摸动作不符合预定的分辨率调整条件；则进行下一步触摸动作判断。
判断触摸动作步骤，判断检测到的触摸动作是否与预定的分辨率调整动作相对应，根据判断结果确定触摸动作是否符合预定的分辨率调整条件，当触摸动作与预定的分辨率调整动作不相对应时，认为不符合预定的分辨率调整条件，禁止对趋势图的分辨率进行调整。
如果触摸动作的位置坐标在趋势图的显示区域内，且触摸动作与预定的分辨率调整动作相对应时，即当上述两个条件都满足时，才认为符合预定的分辨率调整条件，允许对期望调整的趋势图的分辨率进行调整。如果任一条件不满足，则认为不符合预定的分辨率调整条件，禁止对趋势图的分辨率进行调整。
步骤250，根据动作信息和预设的计算方法计算调整后的趋势图显示的分辨率。
本步骤中，分辨率的计算方法根据分辨率的调整模式和预定的分辨率调整动作而确定。
分辨率的调整模式可以有以下两种类型：
1．确定种类分辨率：支持确定的几种分辨率，分辨率由小到大排列，比如分辨率提供（1，2，3，4，5，6，7，8，9，10），根据触摸动作将分辨率调整为对应的等级。该种类型是通过对话框设置分辨率的主要方式。
2. 动态范围分辨率：支持分辨率在一定范围内动态调整，如界面分辨率在（Range1，Range2）之间，则分辨率可以为该范围之间的任一值，具体值由计算得到。
预定的分辨率调整动作可以有以下几种类型：
1.单手指的触摸操作，判断的触摸信息为单手指触摸位置的变化。比如单个手指在某个方向的滑动，可根据滑动距离计算分辨率的调整。对于这种情况，分辨率调整动作是单个触点的动作，例如调整模式是确定种类分辨率时，分辨率由小到大排列，分辨率调整动作可以设定为是单个触点的点击，根据触摸动作是增大还是减少在分辨率序列中调整，比如分辨率提供（1，2，3，4，5，6，7，8，9，10），如果当前为5，当动作是增大分辨率时，则新的分辨率为6，减少时则新的分辨率为4。当调整模式配置为动态范围分辨率时，分辨率调整动作可以设定为是单个触点的滑动，分辨率计算单元可根据单个触点的滑动方向和距离计算调整后的分辨率。例如规定向左滑动为减小分辨率，向右滑动为增加分辨率，每滑动设定距离分辨率增大或减小一个等级或设定值。
2.多手指的触摸操作，判断的触摸动作信息包括触摸点信息，和触摸点的距离信息。预定的分辨率调整动作为多个触点的滑动，预设的计算方法为：
根据动作信息中多个触点初始接触触摸屏时的位置信息计算多个触点的初始几何量；
根据动作信息中该多个触点最终的位置信息计算多个触点的滑动后几何量；
根据以下公式计算调整后的分辨率：
G1/ G2 = Precise1/Precise2
其中，G1为初始几何量，G2为移动后几何量，Precise1为原分辨率，Precise2为调整后的分辨率。
比如预定的分辨率调整动作为两个触点的滑动时，计算两个手指之间的距离，通过距离关系来计算分辨率的调整，主要用到的动作信息为初始和结束接触点信息，当用户两个手指接触触摸屏时产生初始触点信息，两个手指在触摸屏上滑动，两个手指距离减小的时候，分辨率变小，单屏幕显示时间段变大，两个手指距离变大时，分辨率变大，单屏幕显示时间段变小，当用户两个手指从触摸屏抬起的时候认为动作结束。两个手指定义为Finger A 和Finger B，假设该动作在某一时刻的接触点坐标为（Xfa，Yfa）（Xfb，Yfb），其中Xfa和Xfb为水平方向坐标，Yfa和Yfb为垂直方向坐标，这两个手指的某一时刻的坐标定义为一个四元组（Xfa，Yfa，Xfb，Yfb）。
在计算方法上可以要求，初始接触位位置为（Xa1，Ya1，Xb1，Yb1），结束接触位置为（Xa2，Ya2，Xb2，Yb2），这里要求Xa1<Xa2，Xb1<Xb2，界面的原分辨率为Precise1，调整后的分辨率为Precise2，调整后的分辨率要求满足以下公式：
（Xa1-Xb1）/(Xa2-Xb2) = Precise1/Precise2
该公式的界面效果为 Xa1和Xb1之间显示的时间范围和Xa2和Xb2的显示时间范围相同。该公式为示意公式，没有考虑边界情况。
当预定的分辨率调整动作为三个以上（包括三个）触点的滑动时，可计算三个以上触点围合成的几何图形的面积，通过面积关系来计算分辨率的调整。
3.分辨率增大或减少的动作，每次动作，***预定义增大或减少一个单位的分辨率，比如某个方向的短促滑动动作，可为单个手指或多个手指的滑动，当滑动速度大于某一速度值时，认为是一个有效调整动作，分辨率计算单元根据滑动的方向和次数对原分辨率进行逐级递增或递减。
步骤270，将界面上用户期望调整的趋势图按调整后的分辨率显示数据。
实施例二：
将界面上用户期望调整的趋势图按调整后的分辨率进行显示时，显示的数据点可以是固定不变的数据点，也可以是随分辨率变化的数据点。
本实施例与上述实施例不同的是对于不同分辨率或不同范围的分辨率定义了不同的需要显示的数据点，在确定调整后的分辨率后，需要确定该分辨率所对应的数据点。可通过以下几种方式确定不同分辨率所对应的可显示数据点。
定义不同分辨率下的可显示数据：该方法定义不同分辨率下可显示的数据，可根据不同分辨率对应的不同数据抽样率确定调整后分辨率所对应的可显示数据点。比如确定种类分辨率（1，2，3，4，5，6，7，8，9，10），可分别定义这10种分辨率下显示的数据点。而对于动态范围分辨率（Range1，Range2），需要把范围做一个划分，确定不同范围的分辨率所对应的显示点。
定义各数据点在不同分辨率下的可显示性：该方法定义数据在不同分辨率下是否可显示，根据数据点对不同分辨率的可显示性确定调整后分辨率所对应的可显示数据点。比如确定种类分辨率由小到大排列，（1，2，3，4，5，6，7，8，9，10），对于数据点P1，定义P1点在大于等于5时可显示，小于5时不可显示，而对于动态范围分辨率（Range1，Range2），可将该范围的某一分辨率PrceiseA设置为阈值，P1在分辨率大于PrceiseA时可显示，小于PrceiseA时不显示。
基于上述构思，趋势图分辨率调整装置与实施例一不同的是还包括可显示数据点确定单元，趋势图分辨率调整装置的结构示意图如图7所示，包括动作识别单元110、调整判断单元120、分辨率计算单元130、可显示数据点确定单元150和显示单元140。可显示数据点确定单元150用于根据分辨率计算单元130计算出的调整后分辨率确定该调整后分辨率所对应的可显示数据点，例如根据不同分辨率对应的不同数据抽样率确定调整后分辨率所对应的可显示数据点，或者根据数据点对不同分辨率的可显示性确定调整后分辨率所对应的可显示数据点；显示单元140将可显示数据点按调整后的分辨率显示在趋势图中。
一种具体实例中，显示单元140在按调整后的分辨率显示数据时，为了保持显示的连贯性，采用渐进式处理或动画式处理。如图8所示，显示单元140包括先期显示子单元141、可显示性判断子单元142和后期显示子单元143，先期显示子单元141用于在趋势图上按照调整后的分辨率显示原分辨率对应的可显示数据点；可显示性判断子单元142用于根据调整后分辨率所对应的可显示数据点，识别数据点分别对于原分辨率和调整后分辨率的可显示性，并据此判断当前趋势图上显示的数据点是否需要调整；后期显示子单元143用于在需要调整时对数据点进行显示或隐藏处理，将趋势图上显示的数据点调整为调整后分辨率所对应的可显示数据点，在不需要调整时保持趋势图上显示的数据点不变。例如：在数据点对于原分辨率为不可显示、而对于调整后分辨率为可显示时，后期显示子单元143将该数据点以逐帧增大亮度的方式显示在趋势图上，在数据点对于原分辨率为可显示、而对于调整后分辨率为不可显示时，后期显示子单元143将该数据点以逐帧减小亮度的方式从趋势图上消隐。
基于上述构思的分辨率调整方法的流程如图9所示，与实施例一不同的是在步骤250和步骤270之间增加了步骤260，在步骤260中根据调整后的分辨率确定趋势图上需要显示的数据点，例如，预先设置分辨率和抽样率对应表，当分辨率调整确定后，从采样数据中按照该分辨率对应的数据抽样率进行抽取，抽取出的数据为该分辨率所对应的可显示数据点；或者查询数据点对该分辨率的可显示性，从而确定该分辨率下可显示的数据点。
例如：本实施例的一个显示的例子是，每个数据点的显示位置是不连接的离散点，当前显示宽度内可显示9个数据点（P1，P2，P3，P4，P5，P6，P7，P8，P9），当前分辨率为Precise1，根据定义，数据点P1，P3，P5，P7，P9在分辨率大于PrceiseA时可显示，数据点P2，P4，P6，P8大于PreciseB时可显示，PreciseB>PreciseA，即需要在更高的分辨率才能显示P2，P4，P6，P8。
当分辨率由Precise1调整为Precise2时，因为Precise1>PreciseB，PreciseB> Precise2 >PreciseA，则界面按照Precise2所对应的数据点显示，只显示数据点P1，P3，P5，P7，P9。当分辨率由Precise2调整为Precise1时，则界面以Precise1所对应的数据点显示，可显示数据点P1，P2，P3，P4，P5，P6，P7，P8，P9。
在本实施例中，不同的分辨率可能对应不同的数据点，即趋势图上显示的数据点为根据分辨率而设计。
在步骤270中将步骤260确定的数据点按调整后分辨率进行显示。当调整后的分辨率所对应的数据点与原显示的数据点相同时，步骤270中的显示不变。当调整后的分辨率所对应的数据点与原显示的数据点不同时，步骤270中显示的数据点将会发生变化，有的数据点还继续显示，有的数据点原来没有显示，但根据新分辨率确定的数据点需要将其显示出来，有的数据点原来有显示，但根据新分辨率确定的数据点需要将其隐藏，即不再显示该数据点。显示时可直接将步骤260确定的数据点按调整后分辨率进行显示，但这样在视觉效果上存在一个突变，为了消除该视觉突变，可在从原显示数据点变为新数据点时进行一些处理，使其以渐进式或动画的方式逐渐变化。处理流程如图10所示，包括以下步骤：
步骤271，在趋势图上按照调整后的分辨率显示原分辨率对应的可显示数据点，而不是不直接显示调整后分辨率下可显示数据点。
步骤272，根据调整后分辨率所对应的可显示数据点，判断当前趋势图上显示的数据点是否需要调整。如果需要，则执行步骤273，否则执行步骤275，保持趋势图上显示的数据点不变。
步骤273，对数据点进行渐进式显示或渐进式消隐处理。
如果数据点对于原分辨率为不可显示，而对于调整后分辨率为可显示，则将该数据点以逐帧增大亮度的方式显示在趋势图上；如果数据点对于原分辨率为可显示，而对于调整后分辨率为不可显示，则将该数据点以逐帧减小亮度的方式从趋势图上消隐。
步骤274，将趋势图上显示的数据点调整为调整后分辨率所对应的可显示数据点。
界面显示数据点的方式主要有两种情况：
1. 以离散的点显示，数据点的显示为互不连接的点，如图1所示。
2. 以点的连线显示，数据点的显示为互相连接的点，如图11所示。
一个显示点互相不连接的例子是，当前界面显示九个点（P1，P2，P3，P4，P5，P6，P7，P8，P9），当前分辨率为Precise1，P1，P3，P5，P7，P9在分辨率大于PrceiseA时可显示，P2，P4，P6，P8大于PreciseB时可显示，PreciseB>PreciseA，即需要在更高的分辨率才能显示P2，P4，P6，P8。
当分辨率由Precise1调整为Precise2时，Precise1>PreciseB，PreciseB> Precise2 >PreciseA，则界面先按Precise2进行显示，显示的数据点为Precise1对应的数据点P1，P2，P3，P4，P5，P6，P7，P8，P9，数据点P2，P4，P6，P8的亮度在一定时间内渐渐变低，直到不显示，最后显示的是Precise2对应的数据点P1，P3，P5，P7，P9。
当分辨率由Precise2调整为Precise1时，则界面先按Precise1进行显示，显示的数据点为Precise2对应的数据点P1，P3，P5，P7，P9，数据点P2，P4，P6，P8的亮度在一定时间内渐渐变高，直到亮度为正常值，最后显示为Precise1对应的数据点P1，P2，P3，P4，P5，P6，P7，P8，P9。
一个显示点互相连接的例子，当前界面显示九个点（W1，W2，W3， W4， W5， W6， W7， W8， W9）的曲线，当前分辨率为Precise1，数据点W1， W3， W5， W7， W9在分辨率大于PrceiseA时可显示，数据点W2，W4，W6，W8大于PreciseB时可显示，PreciseB>PreciseA，即需要在更高的分辨率才能显示W2，W4，W6，W8。
当分辨率由Precise1调整为Precise2时，Precise1>PreciseB，PreciseB> Precise2 >PreciseA，则界面先以Precise2进行显示，显示的数据点为Precise1对应的数据点W1，W2，W3，W4，W5，W6，W7，W8，W9及其之间连接成的曲线Curve1，再以动画的形式隐藏数据点W2，W4，W6，W8，最后显示为Precise2对应的数据点W1，W3，W5，W7，W9及其之间连接成的曲线Curve2。曲线Curve1到Curve2的动画的一个方式为，这里以W2为例，W4，W6，W8类似，Curve1的W1和W2之间曲线、W2点、W2和W3之间曲线亮度渐渐变低，而Curve2的W1和W3之间曲线亮度渐渐变高，直到Curve1不显示，Curve2正常显示。
当分辨率由Precise2调整为Precise1时，则界面先以Precise1进行显示，显示的数据点为Precise2对应的数据点W1，W3，W5，W7，W9及其之间连接成的曲线Curve2，再以动画的形式显示数据点W2，W4，W6，W8，最后显示为Precise1对应的数据点W1，W2，W3，W4，W5，W6，W7，W8，W9及其之间连接成的曲线Curve1。 曲线Curve2到Curve1的动画的一个方式为，这里以W2为例，W4，W6，W8类似，Curve1的W1和W2之间曲线、W2点、W2和W3之间曲线亮度渐渐变高，而Curve2的W1和W3之间曲线亮度渐渐变低，直到Curve1正常显示，Curve2不显示。
实施例三：
上述实施例是对触摸动作响应后，流程则结束，开始下一次的动作检测。本实施例与上述实施例不同的是：触摸动作分为启动分辨率调整动作和分辨率调整动作。请参考图12，趋势图分辨率调整装置包括动作识别单元1100、调整启动判断单元1500、调整判断单元1200、分辨率计算单元1300和显示单元1400。动作识别单元1100用于接收触摸屏输出的触摸信息，根据触摸信息识别用户触摸操作的动作，生成动作信息；调整启动判断单元1500用于判断检测到的触摸动作和预定的分辨率调整启动动作是否相对应，如果不相对应，则界面上的趋势图维持原分辨率；如果触摸动作和预定的分辨率调整启动动作相对应，则界面启动分辨率调整过程；调整判断单元1200用于在调整启动判断单元启动分辨率调整过程后判断动作识别单元检测到的触摸动作是否符合预定的分辨率调整条件；分辨率计算单元1300用于在调整判断单元判断触摸动作符合预定的分辨率调整条件时，根据动作识别单元生成的动作信息和预设的计算方法计算调整后的趋势图显示的分辨率；显示单元1400用于根据分辨率计算单元输出的调整后分辨率将界面上用户期望调整的趋势图按调整后的分辨率显示数据，并在检测到的触摸动作不符合预定的分辨率调整条件时，使界面上的趋势图维持原分辨率。
基于本实施例的构思调整分辨率的过程如图13所示，包括以下步骤：
步骤2100，初始状态是界面显示数据，监护仪的趋势图界面处于打开状态，按当前分辨率显示病人的趋势数据。
步骤2200，检测用户对触摸屏操作，识别触摸操作的动作。用户期望调整界面的分辨率时，用户和触摸屏接触，执行触摸操作以改变为用户期望的显示分辨率，该步骤为用户和监护仪的交互过程。
预定的分辨率调整启动动作的一个实例为两个手指操作，两个触摸点，当两个手指接触触摸屏、两个手指的距离发生时，则认为是启动动作。
步骤2300，根据识别用户动作，判断该触摸动作是否和预定的分辨率调整启动动作相对应605，如果对应则执行步骤2400，启动分辨率调整，如果不对应则不响应用户动作，继续按当前分辨率显示病人的趋势数据。
步骤2500，用户通过分辨率调整动作调整分辨率，界面以新分辨率显示原分辨率可显示数据。该步骤根据分辨率的调整动作信息和调整方法计算新的显示分辨率，可采用上述实施例的方案，也可采用以下方案：
预定的分辨率调整启动动作和分辨率调整动作都为两个手指在触摸屏上滑动。当检测到两个触点之间的距离增加时，根据步骤2300的判断，启动分辨率调整。紧接着检测两个触点之间的距离，根据两个触点之间的距离计算调整后的分辨率，初始值检测到分辨率启动动作时的点，分辨率调整动作的每次计算以当前触摸位置坐标更新。两个触点之间的距离减小，分辨率变小，单屏幕显示时间段变大，两个触点之间的距离变大，分辨率变大，单屏幕显示时间段变小，当用户两个手指从触摸屏抬起的时候认为动作结束。
步骤2600， 用户结束分辨率调整动作，界面显示新分辨率下可显示数据，完成整个分辨率调整。
本领域技术人员可以理解，上述实施方式中各种方法的全部或部分步骤可以通过程序来指令相关硬件完成，该程序可以存储于一计算机可读存储介质中，存储介质可以包括：只读存储器、随机存储器、磁盘或光盘等。
以上内容是结合具体的实施方式对本发明所作的进一步详细说明，不能认定本发明的具体实施只局限于这些说明。对于本发明所属技术领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干简单推演或替换。
