Description

电子书页面显示方法、装置和终端设备
本申请要求于2017年3月30日提交中国专利局、申请号为201710202333.6，发明名称为“电子书页面显示方法、装置和终端设备”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及数据处理技术领域，尤其涉及一种电子书页面显示方法、装置和一种终端设备。
背景技术
电子书是利用计算机技术将文字、图片、声音、影像等信息内容数字化的出版物。随着互联网技术应用的越来越广泛，传统的纸质阅读方式已逐渐被电子书取代，人们越来越趋向于利用互联网和计算机技术，通过用于阅读电子书的阅读应用下载电子书进行阅读。
在阅读电子书的过程中，用户最经常做的操作是电子书翻页操作。翻页操作过程中，电子书页面会随着用户的滑动操作显示相应的翻页效果，在整个显示界面中，一部分显示为当前页面(已阅读的页面)的内容，一部分显示为下一页面(待阅读的页面)的内容，而另一部分则显示为当前页面的翻折部分(即当前页面被翻折的那部分，其为当前页面背面的一部分)，以形成完整的翻页效果。
目前，翻页过程中当前页面的翻折部分通常仅显示为固定的颜色，如，显示为白色或显示为设定的纸张颜色。这种简单的颜色显示方式使得翻页过程中的页面颜色不能够很好地进行匹配，影响电子书的页面显示效果。
发明内容
本申请实施例提供了一种电子书页面显示方法、装置和一种终端设备，以解决目前电子书翻页过程中，页面颜色不能够很好地进行匹配，影响电子书的页面显示效果的问题。
根据本申请实施例，一种电子书页面显示方法，包括：确定接收到对当前显示的电子书图像页面的翻页操作后，获取所述电子书图像页面的边缘纸张颜色和页面内容，其中，所述边缘纸张颜色用于指示距离所述电子书图像页面边缘设定距离内的纸张的颜色；使用所述边缘纸张颜色和所述页面内容，绘制并显示所述翻页操作所操作的电子书图像页面的翻折部分。
通过本发明实施例提供的电子书页面显示方案，在用户想要对正在阅读的电子书页面尤其是电子书图像页面进行翻页，进行了相应的翻页操作后，电子书阅读应用所在设备，如移动终端、台式机等，在接收到该翻页操作后，会首先获取当前显示的电子书图像页面的页面边缘的纸张颜色以及页面内容，进而以此为依据绘制翻页操作过程中显示的电子书图像页面的翻折部分。与传统的使用固定颜色显示电子书图像页面的翻折部分的方式相比，一方面，边缘纸张颜色作为电子书图像页面颜色的一部分，与电子书图像页面的匹配度更高，颜色搭配也更为协调，有效改进了电子书图像页面的显示效果，提升用户阅读体验；另一方面，与传统的页面颜色分析需要对整个页面的颜色数据进行采集和分析相比，边缘纸张颜色既能有效反映当前的电子书图像页面情况，也大大降低了颜色数据的采集和分析的数据处理量，提升了电子书绘制和显示 效率，也进一步提升了用户的阅读体验。

具体实施方式
下面结合附图(若干附图中相同的标号表示相同的元素)和实施例，对本申请实施例的具体实施方式作进一步详细说明。以下实施例用于说明本申请，但不用来限制本申请的范围。
本领域技术人员可以理解，本申请实施例中的“第一”、“第二”等术语仅用于区别不同步骤、设备或模块等，既不代表任何特定技术含义，也不表示它们之间的必然逻辑顺序。
实施例一
参照图1，示出了根据本申请实施例一的一种电子书页面显示方法的步骤流程图。
本实施例的电子书页面显示方法包括以下步骤：
步骤S102：确定接收到对当前显示的电子书图像页面的翻页操作后，获取电子书图像页面的边缘纸张颜色和页面内容。
本申请实施例中，电子书图像页面意指电子书页面内容中包含图像，并且，该图像中存在与电子书页面的边界区域相重合的部分。其中，电子书页面的边界区域可以设置为进行边缘纸张取色的区域，如距离电子书图像页面边缘设定距离内的区域。
边缘纸张颜色用于指示距离电子书图像页面边缘设定距离内的纸张的颜色。其中，设定距离可以由本领域技术人员根据实际需求适当设置，可在电子书图像页面边缘区域取色即可，如，设置为四边均距离电子书图像页面的四个页面边界一个像素或者一毫米的距离等等。
边缘纸张颜色能够有效反映当前电子书图像页面的构色情况，例如，电子书封面或者电子书页面的某个或某几个边界区域中设置有插图的页面，其边缘纸张颜色可能包括多种颜色；又例如，若当前电子书页面的主要内容虽然为文字，但使用了有不同颜色元素的图片背景或者装饰背景时，其边缘纸张颜色也可能包括多种颜色。对这些边缘纸张颜色进行提取，将其与电子书图像页面的页面内容(如图像和/或文字)相结合，作为绘制翻页过程中显示的电子书图像页面的翻折部分的依据，在提升颜色数据的处理效率的同时，因其与当前显示的电子书图像页面的匹配度较高，颜色搭配更为 协调，有效提升了电子书页面尤其是电子书图像页面显示的效果。
对当前显示的电子书图像页面的页面内容的获取可以由本领域技术人员根据实际情况设置任意适当的方式实现，如，在电子书页面绘制时获取绘制的页面内容的信息，或者，确定电子书页面的绘制区域，进而从该区域中获取绘制的内容等等，本申请实施例对此不作限制。
此外，确定接收到对当前显示的电子书页面的翻页操作的实现方式，同样可以由本领域技术人员根据实际情况适当设置，例如，检测到用户通过触摸屏对当前显示的电子书页面进行了操作，根据其轨迹坐标确定该操作为滑动操作，则认为用户对当前电子书页面进行了翻页操作；或者，根据鼠标的操作轨迹确定该操作为滑动操作，认为对电子书页面进行了翻页操作等，本申请实施例对此也不作限制。
另外，如无特别说明，本申请实施例中，当前显示的电子书页面意指已阅读过、待翻页的页面。
步骤S104：使用边缘纸张颜色和页面内容，绘制并显示翻页操作所操作的电子书图像页面的翻折部分。
翻页过程中的电子书显示界面通常包括第一区域、第二区域和第三区域。其中，第三区域为翻页操作所操作的电子书图像页面的翻折部分的区域，第一区域为当前显示的电子书图像页面中，未被翻折部分遮挡的区域，第二区域为当前显示的电子书图像页面的下一页面中的被显示区域。
一种翻页操作过程中显示的电子书页面如图2所示，为便于区分，本申请实施例中，使用第一电子书页面表示当前显示的电子书图像页面(即已阅读过、待翻页的图像页面)，使用第二电子书页面表示待显示的电子书页面(即待阅读的、翻页操作后显示的页面，可以为图像页面，也可以为非图像页面)。图2中，四条外边线AB、BC、CD、DA表示电子书页面的边界，A、B、C、D为页面的四个顶点，翻页操作过程中显示的电子书页面的效果可以从其中的任何一个顶点开始，图2中以从C顶点开始为例。EF表示翻页操作形成的折边，折边与页面边界BC的交点为E，与页面CD的交点为F。折边EF将电子书页面划分为翻页初始操作点所在的区域和当前操作点所在的区域，这两个区域组成整个电子书页面。其中，初始操作点所在的区域为第二区域(图2中的斜线区域)，第二区域相对于折边EF的轴对称区域，即EC’F区域(C’为第一区域沿折边EF翻页后，顶点C的位置)，为第三区域(图2中的竖线和横线交叉区域)，除此之外的区域为第一区域(当前操作点所在区域中，除第三区域外的区域，图2中的横线区域)。
本申请实施例中，对于第三区域，使用边缘纸张颜色和页面内容进行绘制。其中，边缘纸张颜色可以作为第三区域中电子书页面纸张颜色，根据该区域的大小和对应的当前电子书页面的位置，绘制相对应的页面内容。第三区域的大小、对应于当前电子书页面的位置、该区域应当显示的页面内容的确定及反向处理、以及第一区域和第二区域的绘制均可由本领域技术人员采用任意适当的手段实现，本申请实施例对此不作限制。绘制完成的第一区域、第二区域和第三区域形成完整的翻页操作过程中的电子书页面呈现效果。
另外，需要说明的是，在翻页操作过程中，第三区域会随着用户的翻页操作而变化，包括但不限于大小的变化、形状的变化等，其在一个翻页操作过程中并不是一成 不变的，图2中的第三区域也仅为示例性说明，实际中，也可能存在矩形或者梯形的第三区域，并且，以C顶点为翻页顶点为例，随着用户从右向左的滑动操作，第三区域将逐渐增大，绘制的页面内容也会逐渐增多。
通过本实施例的电子书页面显示方法，在用户想要对正在阅读的电子书页面尤其是电子书图像页面进行翻页，进行了相应的翻页操作后，电子书阅读应用所在设备在接收到该翻页操作后，会首先获取当前显示的电子书图像页面的页面边缘的纸张颜色以及页面内容，进而以此为依据绘制翻页操作过程中显示的电子书图像页面的翻折部分。与传统的使用固定颜色显示电子书图像页面的翻折部分的方式相比，一方面，边缘纸张颜色作为电子书图像页面颜色的一部分，与电子书图像页面的匹配度更高，颜色搭配也更为协调，有效改进了电子书图像页面的显示效果，提升用户阅读体验；另一方面，与传统的页面颜色分析需要对整个页面的颜色数据进行采集和分析相比，边缘纸张颜色既能有效反映当前的电子书图像页面情况，也大大降低了颜色数据的采集和分析的数据处理量，提升了电子书绘制和显示效率，也进一步提升了用户的阅读体验。
本实施例的电子书页面显示方法可以由任意适当的具有数据处理能力的设备执行，包括但不限于：移动终端、电子书阅读器或台式机等。
实施例二
参照图3，示出了根据本申请实施例二的一种电子书页面显示方法的步骤流程图。
本实施例的电子书页面显示方法包括：
步骤S202：判断当前显示的电子书页面是否为电子书图像页面；若为电子书图像页面，则执行步骤S204；若不为电子书图像页面，则执行步骤S208。
本申请实施例的电子书页面显示方法主要针对电子书图像页面，即，电子书页面内容中包含图像，并且，该图像中存在与电子书页面的边界区域相重合的部分的页面，如，电子书封面，或者电子书内容页面中以图片为背景或者设置有装饰背景的页面，或者，电子书内容页面的边界区域设置有插图的页面等等。
在一种可行方式中，可以根据当前显示的电子书页面的透明度值，判断当前显示的电子书页面是否为电子书图像页面。若透明度值指示为不透明，则可以确定当前显示的电子书页面为电子书图像页面。但不止于此，若虽然透明度值指示为透明，但经进一步判断距离当前显示的电子书页面边缘设定距离内的区域中是否存在图片和/或装饰背景后，确定存在，则可确定当前显示的电子书页面也为电子书图像页面。
这是因为，电子书页面在绘制时，会先进行排版，再确定绘制待呈现元素的方式，然后通过适当的方式渲染绘制。其中，待呈现元素既包括待绘制元素的具体内容，如文字、图片、视频、装饰背景等，也包括绘制待绘制元素的载体，如画板。本申请实施例中，将画板设置为透明。如果电子书页面里存在全屏的图片或者全屏的装饰背景，则结果图表现为全不透明；如果是纯文字则表现为具有部分全透明色值，如，纯文字页面的边界区域表现为透明色。但除此之外，如果存在文字和图片混合排版的情况，比如文字将中间的图片环绕起来，或者上下两部分文字中间设置有位于版心范围内的图片，则电子书页面的边界区域仍表现为透明色。但如果文字和图片混合排版情况下，图片不在版心范围内，且图片的一部分位于页面的边界区域内，则在此情况下，该电子书页面的边界区域中，该图片覆盖的范围内也不透明。这种通过透明度进行判断的 方式，大大提高了确定电子书页面是否为电子书图像页面的效率。但不限于此，其它确定当前显示的电子书页面是否为电子书图像页面的方式也同样适用，如在电子书页面排版过程中分析可视元素区域、根据电子书页面中的图像信息和/或装饰背景信息进行判断等。
步骤S204：确定接收到对当前显示的电子书图像页面的翻页操作后，获取电子书图像页面的边缘纸张颜色和页面内容。
其中，边缘纸张颜色用于指示距离电子书图像页面边缘设定距离内的纸张的颜色。
使用纸张边缘颜色的色值扫描代替传统的全图扫描，可以提高颜色提取和判断的效率。并且，该方式与生活常识里的图书页面边缘即未经印刷的纸张的原理相吻合。可选地，纸张边缘选择距离电子书页面上下左右边界1个像素的区域。
在一种可行方式中，可以通过确定距离电子书图像页面边缘设定距离内的区域；获取所述区域内的像素的像素值；根据获取的像素值确定边缘纸张颜色。以RGB色彩空间为例，每一个像素的像素值都对应有一个颜色，如，RGB(255，255，255)为白色，RGB(0，0，0)为黑色，RGB(255，0，0)为红色等等。获得了区域内像素的像素值，就可以根据这些像素值确定相应的边缘纸张颜色。需要说明的是，以上RGB色彩空间仅为示例性说明，本领域技术人员可以根据实际需要选择相应的色彩空间，如HSV色彩空间、HSL色彩空间等，本申请实施例对此不作限制。
因为纸张颜色可能有多种情况，因此获取到的像素值指示的颜色也可能指示多种颜色情况。在此情况下，一种可行方式中，可以根据获取的像素值确定区域内包含的颜色的数量，进而确定边缘纸张颜色。具体地，在确定时，可以采用以下方式中的至少一种，包括：(1)若所述区域内包含的颜色的数量大于第二设定阈值且小于第三设定阈值，则将所有像素值中，占比最多的像素值对应的颜色确定为待绘制的边缘纸张颜色；其中，第二设定阈值和第三设定阈值均为正整数，第二设定阈值大于1，且第二设定阈值小于第三设定阈值；其中，第二设定阈值和第三设定阈值的具体数值可以由本领域技术人员适当设置，不会使颜色过于混杂即可。例如，第二设定阈值设定为2，第三设定阈值设定为5；再例如，第二设定阈值设定为2，第三设定阈值设定为采样的像素的数量的30％取整等等。例如，若采集了所述区域内共1000个像素的像素值，其中，300个像素的像素值为(255，255，255)，200个像素的像素值为(0，0，0)，500个像素的像素值为(255，0，0)，则可以将占比最多的像素值对应的颜色，即(255，0，0)对应的红色，确定为待绘制的边缘纸张颜色。(2)若所述区域内包含的颜色的数量大于或等于第三设定阈值，则将设定颜色确定为待绘制的边缘纸张颜色。其中，设定颜色也可以由本领域技术人员根据实际情况适当设置，如设置为白色，或者设置为淡米色、淡黄色等。(3)若所述区域内仅包含一种颜色，则可以将该种颜色确定为边缘纸张颜色。
当颜色数量在第二设定阈值和第三设定阈值范围内时，表明当前显示的电子书图像页面中，仅有少数的几种颜色，页面颜色相对干净，此时，使用占比最多的像素值对应的颜色作为边缘纸张颜色，过渡自然，颜色搭配效果好。而当颜色数量大于或等于第三设定阈值时，表明当前显示的电子书图像页面颜色较杂，不容易确定匹配度较好的颜色，而且，杂色容易为用户带来视觉疲劳，仍选用其中占比最多的像素值对应 的颜色也不能达到缓解用户视觉疲劳的效果。因此，若当前显示的电子书图像页面的颜色较为复杂，则可以将设定颜色确定为电子书图像页面的边缘纸张颜色，以为用户带来更好的阅读体验。
在另一种可行方式中，可以根据获取的像素值确定区域内包含的颜色的数量与获取的像素值的数量的比值，进而确定边缘纸张颜色。具体地，在确定时，可以采用以下方式中的至少一种，包括：(1)若所述比值大于第一设定比值且小于第二设定比值，则将所有像素值中，占比最多的像素值对应的颜色确定为待绘制的边缘纸张颜色；其中，第二设定比值大于【1/(获取的像素值的数量)】，且第一设定比值小于第二设定比值；其中，第一设定比值和第二设定比值的具体数值可以由本领域技术人员适当设置，不会使颜色过于混杂即可。(2)若所述区域内包含的颜色的数量与获取的像素值的数量的比值大于或等于第二设定比值，则将设定颜色确定为所述待绘制的边缘纸张颜色。其中，设定颜色也可以由本领域技术人员根据实际情况适当设置，如设置为白色，或者设置为淡米色、淡黄色等。(3)若所述区域内仅包含一种颜色，则可以将该种颜色确定为边缘纸张颜色。
此外，表现为百分数形式的比例也包含在本申请实施例的“比值”范围内。
电子书图像页面的页面内容，包括但不限于图像和/或文字，可以由本领域技术人员采用适当手段获取，本申请实施例对此不作限制。
步骤S206：使用边缘纸张颜色的页面内容，绘制并显示翻页操作所操作的电子书图像页面的翻折部分。
在一种可行方式中，对于电子书图像页面的翻折部分可以采用先在翻折部分绘制页面内容，再在绘制的页面内容之上，将边缘纸张颜色绘制至整个翻折部分的方式实现。先绘制页面内容，再绘制边缘纸张颜色，可以使得绘制效果具有较好的投射效果，更接近于真实的翻页效果。而对于电子书页面的其它部分，包括当前显示的电子书图像页面中除翻折部分之外的部分，以及当前显示的电子书图像页面的下一页面的显示部分均可以由本领域技术人员根据实际情况选择适当的方式绘制实现。在这些部分均绘制完成后，显示呈现最终的绘制结果。
优选地，还可以对绘制的边缘纸张颜色进行降低透明度的处理，即，在绘制的页面内容之上，将边缘纸张颜色绘制至整个翻折部分后，降低绘制的边缘纸张颜色的透明度，以使最终的呈现效果更为接近真实的翻页效果。在一种可选方式中，在降低边缘纸张颜色的透明度时，可以先判断绘制的边缘纸张颜色的亮度值是否小于第一设定阈值，若小于，则降低绘制的边缘纸张颜色的透明度。其中，第一设定阈值可以由本领域技术人员根据实际情况适当设置，如设置为0.2；对边缘纸张颜色降低透明度的幅度也可以由本领域技术人员根据实际情况适当设置，如降低为原透明度的二分之一。在电子书图像页面中，当亮度值小于某一阈值时，颜色的透明度会较高，使得绘制的页面内容有较为清晰的呈现，一方面与实际翻页效果不符，另一方面也影响用户的阅读体验。降低此种情况下的边缘纸张颜色的透明度，以提高用户阅读体验。
本步骤中，对电子书图像页面的翻折部分进行了重点说明，对于除翻折部分之外的其它部分，可以由本领域技术人员采用任意适当方式进行绘制，在此不再赘述。
此外，本实施例中，使用OpenGL进行电子书图像页面的绘制。OpenGL定义了一个跨编程语言、跨平台的编程接口规格的专业的图形程序接口，其与硬件无关，可 以方便地进行2D或3D图形图像的绘制。但不限于OpenGL，其它方式，如Unity或OpenCL等也同样适用。
为使电子书翻页效果与实际翻页效果更为吻合，本实施例在使用OpenGL绘制翻页效果过程还可以借助构建的圆柱模型或圆锥模型，使构建的圆柱模型或圆锥模型与页面的切线与折边EF重合。通过圆柱模型或圆锥模型，实现电子书页面好像绕着一个斜放着的圆柱模型或圆锥模型进行卷边的翻页效果。以下，以构建圆柱模型为例进行说明。
参考图4，图4中，T0为翻页操作的初始操作点，T1为翻页操作的当前操作点，根据T0到T1的翻页操作，形成折边EF。在图2所示界面的基础上，定义平行于边界CD并且经过初始操作点T0的直线与折边EF的交点H为第一中心点，以第一中心点为原点、边界CD所在的方向为X轴的延伸方向、与边界CD相邻的边界DA或BC所在的方向为Y轴的延伸方向建立第一直角坐标系XYZ(如图4中左下角所示)。在该第一直角坐标系XYZ上构建圆柱模型以及与该圆柱模型相切的页面(为便于区分，下文称构建页面)，该构建页面与页面ABCD平行。对该圆柱模型及其相切的构建页面进行三维旋转，以使旋转后的圆柱模型(图4中虚线部分所示为圆柱模型截面)与构建页面的切线与折边EF重合。然后，将第三区域对应的页面纹理进行切分和旋转后贴在圆柱模型上。
其中，第三区域对应的页面纹理意指当前电子书图像页面的翻折部分所对应的纹理(包括当前电子书图像页面的图像和边缘纸张颜色)。本实施例中，先在旋转后的圆柱模型上绘制当前电子书图像页面的图像，再在绘制在图像之上绘制边缘纸张颜色。其中，在绘制图像时，假设先将图像切分成多个n×m个小方块图，每个方块图有4个顶点，这4个顶点就是纹理顶点；假设将该图像切分为多个三角形块图，每个三角形块图有3个顶点，这3个顶点就是纹理顶点。可以理解的是，切分的块图面积越小，个数越多(纹理顶点也越多)，贴在圆柱模型上的效果就越逼真。其中，纹理如何切分以及切分为多少个块图都可以由本领域技术人员根据实际需要进行设定，本申请实施例对此不作限制。
在进行上述纹理处理时，需要根据第三区域对应的各图像块的纹理顶点在第一直角坐标系内的坐标以及适当的三维旋转公式，计算出各纹理顶点旋转后的坐标。然后，依据旋转后的坐标进行圆柱模型的纹理贴图。
一种可行方式中，可以先根据第三区域对应各图像块的纹理顶点在第一直角坐标系内的坐标，计算在第一直角坐标系旋转为第二直角坐标系X’Y’Z’后各纹理顶点旋转后的坐标，其中，折边EF在第二直角坐标系中的位置相对于折边EF在第一直角坐标系中的位置旋转了(90-a)度，其中a表示当前翻页角度。
如图4中所示，第一直角坐标系以第一中心点H为旋转点、绕Z轴顺时针旋转(90-a)度后，变为第二直角坐标系，第二直角坐标系的原点仍然为第一中心点H，第二直角坐标系与第一直角坐标系中的X轴对应的轴为X’轴，第二直角坐标系与第一直角坐标系中的Y轴对应的轴为Y’轴，第二直角坐标系与第一直角坐标系中的Z轴对应的轴为Z’轴(与Z轴重合)。由于在第一直角坐标系中，圆柱模型与构建页面的切线与折边EF重合，也就是说，圆柱模型与边界CD的夹角为当前翻页角度a，又由于第二直角坐标系相对于第一直角坐标系绕H点顺时针旋转了(90-a)度，因此，圆柱 模型在第二直角坐标系中与Y’轴是重合的，可以说在第二直角坐标系中圆柱模型被“移正”了。同样地，各纹理顶点在进行三维旋转后，也被“移正”，以绘制在“移正”后的圆柱模型上。
与此类似，当使用圆锥模型时，可以对第三区域对应的各图像块的纹理顶点和圆锥模型进行坐标转换处理，转换后的圆锥模型的顶点可以为折边的顶点，如为折边EF的顶点E，进而根据转换后的纹理顶点坐标进行纹理图。其中，坐标转换的具体处理可由本领域技术人员采用适当的数学方式进行，在此不再赘述。
而对于第一区域和第二区域的绘制，则可以由本领域技术人员采用常规手段实现，例如，对于第一区域，先确定区域范围坐标，再获取该坐标范围内的图像的所有像素点的信息，然后在该坐标范围内根据像素点的信息进行图像绘制等；对于第二区域，先确定区域范围坐标，再获取该坐标范围内的图像的所有像素点的信息，和/或，该坐标范围内的文字信息，然后在该坐标范围内根据像素点的信息和/或文字的信息进行绘制等，本申请实施例对第一区域和第二区域的具体绘制方式不作限制。
步骤S208：若所述透明度值指示为透明，且，距离当前显示的电子书页面边缘设定距离内的区域中不存在图片和/或装饰背景，则先在整个翻折部分绘制电子书页面的默认纸张颜色，再在翻折部分绘制电子书页面的页面内容，并显示绘制的结果。
也即，若当前显示的电子书页面不为电子书图像页面，则先在整个翻折部分绘制电子书页面的默认纸张颜色，再在翻折部分绘制电子书页面的页面内容，并显示绘制的结果。例如，当前显示的电子书页面为纯文字页面，或者为图片位于版心范围内的图片和文字混排页面，则使用默认纸张颜色(如羊皮纸颜色)绘制翻折部分，再在其上绘制页面内容，以模仿该种页面的实际翻页效果。可选地，也可以进一步降低绘制的页面内容的透明度，以使模仿效果更好。
通过本实施例，实现了电子书图像页面在翻页过程中的页面投射显示，能够与当前显示的电子书图像页面进行有效的匹配和过渡，改进了电子书图像页面的显示效果，提升用户阅读体验；同时，仅以边缘纸张颜色进行处理，大大降低了颜色数据的采集和分析的数据处理量，提升了电子书图像页面绘制和显示效率，也进一步提升了用户的阅读体验。
本实施例的电子书页面显示方法可以由任意适当的具有数据处理能力的设备执行，包括但不限于：移动终端、电子书阅读器或台式机等。

实施例四
参照图6，示出了根据本申请实施例四的一种电子书页面显示方法的步骤流程图。
本实施例的电子书页面显示方法包括以下步骤：
步骤S402：在接收到对当前显示的电子书图像页面的翻页操作后，获取待显示的页面信息。
其中，待显示的页面信息包括：当前显示的电子书图像页面的页面内容、当前显示的电子书图像页面的边缘纸张颜色、当前显示的电子书图像页面的下一页面的页面内容，其中，边缘纸张颜色用于指示距离电子书图像页面边缘设定距离内的纸张的颜色。
对于当前显示的电子书图像页面的边缘纸张颜色，一种可行的获取方式包括：获取距离电子书图像页面边缘设定距离内的区域中的像素的像素值；根据所述像素值获取当前显示的电子书图像页面的边缘纸张颜色信息。使用纸张边缘颜色的色值扫描代替传统的全图扫描，可以提高颜色提取和判断的效率。并且，该方式与生活常识里的图书页面边缘即未经印刷的纸张的原理相吻合。可选地，纸张边缘选择距离电子书页面上下左右边界1个像素的区域。
因为边缘纸张颜色可能有多种情况，可以针对不同情况确定不同的边缘纸张颜色。因此，在根据所述像素值获取当前显示的电子书图像页面的边缘纸张颜色信息时，可以采用以下方式中的任意一种或几种的组合。具体地，这些方式包括：根据所述像 素值确定距离电子书图像页面边缘设定距离内的区域内包含的颜色的数量；(1)若所述区域内包含的颜色的数量大于第二设定阈值且小于第三设定阈值，则将所有像素值中，占比最多的像素值对应的颜色确定为待绘制的边缘纸张颜色；其中，第二设定阈值和第三设定阈值均为正整数，第二设定阈值大于1，且第二设定阈值小于第三设定阈值，第二设定阈值和第三设定阈值的具体设定可以由本领域技术人员根据实际情况适当设定。(2)若所述区域内包含的颜色的数量大于或等于第三设定阈值，则将设定颜色确定为待绘制的边缘纸张颜色，其中，设定颜色可以由本领域技术人员根据实际情况适当设定，优选地，可设定为白色。(3)若所述区域内仅包含一种颜色，则将该颜色确定为边缘纸张颜色。
在另一种可行方式中，可以根据获取的像素值确定区域内包含的颜色的数量与获取的像素值的数量的比值，进而确定边缘纸张颜色。具体地，在确定时，可以采用以下方式中的至少一种，包括：(1)若所述比值大于第一设定比值且小于第二设定比值，则将所有像素值中，占比最多的像素值对应的颜色确定为待绘制的边缘纸张颜色；其中，第二设定比值大于【1/(获取的像素值的数量)】，且第一设定比值小于第二设定比值；其中，第一设定比值和第二设定比值的具体数值可以由本领域技术人员适当设置，不会使颜色过于混杂即可。(2)若所述区域内包含的颜色的数量与获取的像素值的数量的比值大于或等于第二设定比值，则将设定颜色确定为所述待绘制的边缘纸张颜色。其中，设定颜色也可以由本领域技术人员根据实际情况适当设置，如设置为白色，或者设置为淡米色、淡黄色等。(3)若所述区域内仅包含一种颜色，则可以将该种颜色确定为边缘纸张颜色。
此外，表现为百分数形式的比例也包含在本申请实施例的“比值”范围内。
对于当前显示的电子书图像页面的页面内容和当前显示的电子书图像页面的下一页面的页面内容，可以采用常规获取方式获取。
步骤S404：根据翻页操作的初始操作点和当前操作点确定电子书图像页面的折边；以折边为界，将电子书显示界面划分为初始操作点所在区域和当前操作点所在区域；将初始操作点所在区域作为第二区域；将第二区域相对于折边的轴对称区域作为第三区域；将当前操作点所在区域中，除第三区域外的区域作为第一区域。
翻页过程中的电子书显示界面，在不同区域将显示不同的内容，需要进行区域划分，以便相应内容的绘制和展示。由上述划分可见，第三区域为翻页操作所操作的电子书图像页面的翻折部分的区域，第一区域为当前显示的电子书图像页面中，未被翻折部分遮挡的区域，第二区域为当前显示的电子书图像页面的下一页面中的被显示区域。具体可参照图2中所示的电子书显示界面的第一、第二和第三区域。
步骤S406：使用当前显示的电子书图像页面的边缘纸张颜色和页面内容，绘制电子书显示界面的第三区域；使用当前显示的电子书图像页面的页面内容，绘制电子书显示界面的第一区域；使用当前显示的电子书图像页面的下一页面的页面内容，绘制电子书显示界面的第二区域。
其中，对于第三区域，可以将当前显示的电子书图像页面的页面内容中对应于第三区域的页面内容绘制至第三区域；在绘制的页面内容之上，将边缘纸张颜色绘制至第三区域。
优选地，还可以在绘制的页面内容之上，将边缘纸张颜色绘制至第三区域的步骤 之后，降低绘制的边缘纸张颜色的透明度。
步骤S408：显示绘制结果。
