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描述。
本发明实施例所述的笔迹调整方法可以基于图1是所示的调整笔迹粗细度系统来实现，该系统10可以包括显示设备11和输入设备12，其中，
该显示设备11可以是手机、电纸书、平板电脑、个人数字助理(Personal Digital Assistant，PDA)、台式计算机、便携式计算机、智能电视、媒体播放器等设备。输入设备12包括通信模块和笔迹采集装置，比如触控面板、压力传感器等。该输入设备12可以是写字板。显示设备11和输入设备12可以通过数据线进行通信，也可以无线通信，比如，通过蓝牙(Bluetooth)、移动通信、近距离无线通信(Near Field Communication，NFC)、无线网络(Wireless-Fidelity，WiFi)等，本发明不作限制。
本发明实施例所述的笔迹调整方法也可以基于显示设备单独来实现，该显示设备包括轨迹采集装置(比如触控面板)和显示装置(比如显示面板)。本发明实施例中显示面板和触控面板可以集成于触控显示屏中。显示设备可以通过轨迹采集装置获取到输入笔迹上多个采集点的位置坐标。
请参阅图2，图2是本发明实施例提供的一种笔迹调整方法的流程示意图，该方法包括：
步骤S210：显示设备获取输入笔迹上多个采集点的第一位置坐标。
其中，第一位置坐标为像素坐标，即显示设备上显示装置(也称显示面板)上显示笔迹的像素点的位置坐标。第一位置坐标还可以是尺寸位置坐标，可以理解，像素坐标可以结合屏幕的尺寸、分辨率等信息转换为尺寸坐标。
可选地，该笔迹可以包括一个字符，也可以包括多个字符；对于汉字等包括多个笔画的字符来说，该笔迹还可以包括N笔笔画。可以理解，字符前N笔笔画可以确定需要书写的字符的区域面积。
可选地，显示设备获取输入笔迹上多个采集点的第一位置坐标的一种实施方式可以是：显示设备可以包括笔迹采集装置(比如触控面板)和显示装置(比如显示面板)，第一设备可以通过笔迹采集装置获取用户输入笔迹上多个采集点的触控坐标。触控面板上的触控点可以对应到显示面板中的像素点，进而显示设备可以将各个采集点的触控坐标转换为第一位置坐标，即像素坐标。
可选地，显示设备获取输入笔迹上多个采集点的第一位置坐标的一种实施方式还可以是：显示设备可以与输入设备建立通信连接；输入设备，比如写字板等可以包括笔迹采集装置(比如触控面板)和显示装置(比如显示面板)。输入设备可以通过笔迹采集装置获取用户输入笔迹上多个采集点的触控坐标。触控面板上的触控点可以对应到显示面板中的像素点，进而输入设备可以将各个采集点的触控坐标转换为第二位置坐标，即像素坐标，输入设备可以将多个采集点的第二位置坐标以及该输入设备中显示装置的分辨率发送至显示设备。进而，显示设备在接收到多个采集点的第二位置坐标和输入设备中显示装置的第一分辨率后，在显示设备的显示装置的第二分辨率与输入设备中显示装置的第一分辨率不相同时，显示设备可以根据输入设备中显示装置的第一分辨率以及显示设备中显示装置的第二分辨率计算第一调整系数，并根据第一调整系数分别调整多个采集点的第二位置坐标，获得该多个采集点的第一位置坐标，以使显示设备正常显示该轨迹信息。在输入设备中显示装置的第一分辨率与显示设备的显示装置的第二分辨率相同时，第二位置坐标即为第一位置坐标。其中，第一调整系数用于对第二位置坐标进行缩放处理。
可以理解，该采集点的第一位置坐标可以按照采集的先后顺序生成的位置坐标序列，显示设备还可以获取分别与第一位置坐标一一对应的压力信息、采集时间或停留时间等信息，本发明不作限定。其中，笔迹采集装置还包括压力传感器，笔迹采集装置可以获取用户在该位置坐标按压的压力值。采集时间为该采集该位置坐标时的时间。停留时间可以是该位置坐标的采集时间与下一个位置坐标的采集时间之差。压力信息、采集时间或停留时间等可以进一步用于优化笔迹的绘制，本发明不作限定。
步骤S220：根据所述多个采集点的第一位置坐标计算所述笔迹的区域面积。
其中，笔迹的区域可以是包括笔迹上所有采集点且面积最小的矩形区域，笔迹的区域面积可以是该矩形区域的面积。
计算笔迹的区域面积的一种实施方式可以是：显示设备选定第一坐标点(x1，y1)和第二坐标点(x2，y2)，该第一坐标点喝第二坐标点分别为矩形的区域面积的相对的顶点。笔迹的区域面积S＝|x1-x2|×|y1-y2|。
其中，请参阅图3，图3是本发明实施例提供的一种区域面积计算方法是示意性说明 图，在笔迹采集界面300，矩形ABCD确定的区域即为笔迹的区域301，第一坐标点A的横坐标x1为多个采集点的第一位置坐标中横坐标的最小值，第一坐标点A的纵坐标y1为多个采集点的第一位置坐标中纵坐标的最大值，第二坐标点C的横坐标x2为多个采集点的第一位置坐标中横坐标的最大值，第二坐标点C的纵坐标y2为多个采集点的第一位置坐标中纵坐标的最小值；或者，第一坐标点B的横坐标x1为多个采集点的第一位置坐标中横坐标的最小值，第一坐标点B的纵坐标y1为多个采集点的第一位置坐标中纵坐标的最小值，第二坐标点D的横坐标x2为多个采集点的第一位置坐标中横坐标的最大值，第二坐标点D的纵坐标y2为多个采集点的第一位置坐标中纵坐标的最大值。
需要说明的是，笔迹的区域还可以是其他形式的区域，比如，包括笔迹上所有采集点且面积最小的圆形区域等，区域面积还可以是该圆形区域的面积，区域面积的计算方法还可以是其他的计算方法，本发明不作限定。
例如，笔迹对应的字符为“花”，显示设备计算该字符“花”的区域面积，进而显示设备执行步骤S230，根据该区域面积调整笔迹的粗细度。
本发明一实施例中，当显示设备获取输入的笔迹包括M笔笔画的情况下，所述笔迹的区域面积可以为所述M笔笔画的前N笔笔画对应的字符的区域面积；M为大于等于N的自然数，N为大于等于2或3的自然数；其中，所述前N笔笔画对应的字符包括根据该前N笔笔画预估的用户所要输入的字符；例如，前N笔笔画的笔迹为部分字符“艹”，该前N笔笔画对应字符为包括“艹”的字符，如“花”、“草”等。
显示设备可以识别包括N个笔画的笔迹所形成的字符或部分字符(比如，偏旁部首)通常，偏旁部首在一个汉字中占据空间的比例差别不大，显示设备可以设定各个偏旁部首在一个字符中占据的空间比，并确定该N笔笔画对应的空间比a，进而显示设备根据该N笔笔画的区域面积S 1以及该N笔笔画对应的空间比a计算该笔迹的区域面积S，其中，S＝S 1/a。其中，S 1的计算方法可以参考图3所示的笔迹的区域面积的计算方法，本发明不在赘述。
例如，当显示设备识别笔迹包括的前N笔笔画对应的部分字符为“艹”，若该“艹”在一个汉字中占据的面积比例可以为1/3，“艹”的区域面积S 1为300mm 2，则该则笔迹的区域面积为900mm 2。
显示设备可以在获取包括一个完整字符的笔迹后，再计算该笔迹的区域面积；也可以在获取到一个字符的前N笔笔画，比如前3笔笔画对应的笔迹后，进行估算前N笔笔画笔对应的字符的区域面积，以快速调整笔迹的粗细度，实现在用户输入的过程中，对笔迹的动态调节。
步骤S230：根据所述笔迹的区域面积调整所述笔迹的第一粗细度。
其中，第一粗细度用于调整显示设备根据多个采集点的第一位置坐标和/或该第一位置坐标对应的压力信息、采集时间或停留时间等显示的笔迹的粗细大小。该显示设备可以通过该第一粗细度的线根据多个采集点的第一位置坐标和/或该第一位置坐标对应的压力信息、采集时间或停留时间等直接绘制笔迹；也可以将该第一粗细度作为基础粗细度结合第一位置坐标的对应的压力信息、采集时间或停留时间等信息调整该第一位置坐标对应的点或线段的粗细度，使得显示设备绘制出的轨迹能展示出笔锋。
例如，当第一位置坐标对应的压力值较大时，第一粗细度对应增大使得显示设备对应放大/增粗显示第一位置坐标处的轨迹。
又例如，当第一位置坐标对应的停留时间较长时，第一粗细度对应增大使得显示设备对应放大/增粗显示第一位置坐标处的轨迹。
本发明一实施例中，步骤S230的一种实施方式可以是：显示设备可以预先存储预设对照表，该预设对照表包括至少一个面积，以及所述至少一个面积对应的粗细度，该至少一个面积包括笔迹的区域面积。其中，面积值的单位可以是mm 2、cm 2或其他面积单位，粗细度的单位可以是磅或其他粗细度单位，本发明不作限定。例如，预设对照表如表1所示：
面积S 粗细度
<600mm 2 0.5
601-3500mm 2 2
3501-8000mm 2 4
>8000mm 2 6
表1
显示设备可以根据预设对照表确定笔迹的区域面积对应的第一粗细度，进而，通过该第一粗细度的线绘制和/或显示该笔迹。
可以理解，本发明实施例仅以表1为例来说明预设对照表，本发明实施例中预设对照表还可以是其他形式的预设对照表，本发明不作限定。
步骤S240：根据所述多个采集点的第一位置坐标以所述第一粗细度显示所述笔迹。
可以理解，显示设备可以根据所述多个采集点的第一位置坐标通过该第一粗细度的线绘制和/或显示该笔迹。
本发明一实施例中，步骤S230之后，显示设备根据笔迹的区域面积和笔迹的占用像素面积计算第二调整系数，再根据第二调整系数调整第二粗细度，获得第一粗细度。可选地，第二调整系数可以是笔迹的占用像素面积与笔迹的区域面积的比值。其中，笔迹的占用像素面积为笔迹的实际占用区域的面积。
请参阅图4，图4是本发明实施例提供的一种笔迹的显示界面的示意性说明图。显示设备的显示界面401包括显示装置上所有像素点，像素点通过图中小方块表示，笔迹“大”的区域面积为虚线框402所示的区域的面积，笔迹“大”的占用像素面积为被笔迹“大”所实际占用的区域，即黑色点所占据的面积。
可选地，笔迹的占用像素面积S 1的第一种表达方式可以是：S 1＝L×W。其中，L为笔迹的长度；W为预设粗细度，比如1mm，2mm或其他数值等。笔迹的长度可以通过各个采集点的第一位置坐标计算获得。可选地，该预设粗细度为笔迹的第一粗细度。
对应地，第二调整系数p的一种计算方式可以是：p＝S 1/S。其中，S为笔迹的区域面积，区域面积的计算方法可以参阅步骤S220中相关描述，本发明不在赘述。
可选地，笔迹的占用像素面积的第二种表达方式可以是：笔迹在显示界面所实际占用的像素点个数N 1，如图4中，黑色小方块的个数。对应地，笔迹的区域面积的表达方式可以是如图4中虚线框402所示的区域内内像素点个数N 2。对应地，笔迹的有效面积占比p 的一种计算方式可以是：
Figure PCTCN2017118091-appb-000001
可选地，第二粗细度的调整方法包括：
Figure PCTCN2017118091-appb-000002
其中，b 2为第二粗细度，b 1为第一粗细度，a为预设占比。
例如，第二调整系数为0.5％，预设系数为0.3％，笔迹的第一粗细度b 1为5mm，则第二粗细度b 2为3mm。
可以理解，第二粗细度的调整方法还可以包括其他调整方法，本发明不作限定。
本发明实施例中，显示设备获取输入笔迹上多个采集点的第一位置坐标，根据该多个采集点的第一位置坐标计算笔迹的区域面积，根据笔迹的区域面积调整所述笔迹的第一粗细度，进而，根据多个采集点的第一位置坐标以第一粗细度显示笔迹，实现笔迹粗细度的自动调整，提高用户体验。
而且，通过可表示笔迹繁简程度第二调整系数进一步调整笔迹的粗细度，进而实现笔画较多的笔迹或笔画较少的笔迹以合适的粗细度进行显示。
