实施例一
为了解决现有技术中图像特效实现比较复杂且不灵活的技术问题，本公开实施例提供一种图像特效处理方法。如图1所示，该图像特效处理方法主要包括如下步骤S11至步骤S15。
步骤S11：获取视频图像。
具体的，视频图像可以为实时输入的视频流，例如，短视频应用中的直播视频，也可以为预先存储在终端中的视频图像。其中，终端可以为移动终端，例如智能手机、平板电脑，也可以为固定终端，例如台式电脑。
步骤S12：根据所述视频图像的当前播放进度确定当前图像。
其中，当前图像为当前时刻播放到的图像。
其中，当前时刻可以由用户自定义设置。
具体的，将视频图像显示在终端屏幕上进行播放，当用户有需求或者观看到感兴趣的图像时，可以通过触发相应的按钮获取当前图像，例如拍照或截取终端屏幕。
步骤S13：通过渲染层的图像获取单元从数据存储层获取所述当前图像的上一帧图像。
其中，数据存储层用于存储历史图像，例如，数据存储层可由缓存组成，历史图像存储在缓存中，这样可以快速的存取。
其中，所述历史图像可以为一张或多张。
步骤S14：通过所述渲染层的特效单元将所述上一帧图像与所述当前图像进行透明度叠加处理。
其中，上一帧图像与当前图像均为带有透明度的图像。
具体的，首先确定上一帧图像和当前图像的透明度，然后将两个透明度进行叠加。例如，可以采用公式1-(1-x)ⅹ(1-y)计算得到叠加后的透明度，其中，x为上一帧图像的透明度和y为当前图像的透明度。例如，上一帧图像的透明度为0.5，当前图像的透明度为0.5，则透明度叠加后的图像的透明度为0.75。
步骤S15：将叠加后的图像输出在终端屏幕上显示。
本实施例通过渲染层的图像获取单元从数据存储层获取所述当前图像的上一帧图像；通过所述渲染层的特效单元将所述上一帧图像与所述当前图像进行透明度叠加处理；将叠加后的图像输出在终端屏幕上显示，这样只需要通过修改渲染层即可实现特效，实现起来比较简单灵活。
在一个可选的实施例中，所述方法还包括：
在所述视频图像的播放过程中，通过所述渲染层的图像抓取单元从所述视频图像中抓取所述当前图像的上一帧图像，并将所述上一帧图像存储在数据存储层。
在一个可选的实施例中，所述方法还包括：
通过脚本层向所述渲染层的图像获取单元发送图像获取指令，以触发所述图像获取单元的操作。
其中，脚本层包含脚本程序，及所述脚本程序运行所需要的脚本文件。通过设置脚本中的逻辑实现对渲染层的控制。例如，通过向渲染层的图像获取单元发送图像获取指令，图像获取单元根据图像获取指令从数据存储层中获取所述视频图像的历史图像。
在一个可选的实施例中，所述方法还包括：
通过脚本层向所述渲染层的特效取单元发送控制指令，以触发所 述特效单元的操作。
具体的，通过设置脚本中的逻辑实现对渲染层的控制。例如，通过控制渲染层的特效单元完成一个特效。即向所述渲染层的特效取单元发送控制指令，所述特效单元根据控制指令将所述历史图像与所述当前图像叠加。
在一个可选的实施例中，所述方法还包括：
通过脚本层向所述渲染层的图像抓取单元发送图像抓取指令，以触发所述图像抓取单元的操作。
具体的，通过设置脚本中的逻辑实现对渲染层的控制。例如，通过脚本层向所述渲染层的图像抓取单元发送图像抓取指令，图像抓取单元根据抓取指令抓取图像，并将抓取的图像缓存在存储层中。
进一步的，所述图像抓取指令中包含以下至少一项参数：图像标识、图像坐标、图像宽度、图像高度、所述终端屏幕的分辨率。
其中，图像标识为抓取图像的编号或名称，在每次抓取图像时可以随机生成图像标识。
其中，图像坐标为抓取图像的开始坐标和终点坐标，包括x坐标和y坐标。例如，可以为终端屏幕左上角坐标及右下角坐标。图像坐标具体可以为归一化坐标。当为归一化坐标时，需要根据所述终端屏幕的分辨率计算得到实际坐标，例如，将归一化坐标与所述终端屏幕的分辨率的乘积作为实际坐标。
其中，图像宽度为抓取图像的宽度。
其中，图像高度为抓取图像的高度。
本领域技术人员应能理解，在上述各个实施例的基础上，还可以进行明显变型(例如，对所列举的模式进行叠加)或等同替换。
在上文中，虽然按照上述的顺序描述了图像特效处理方法实施例中的各个步骤，本领域技术人员应清楚，本公开实施例中的步骤并不必然按照上述顺序执行，其也可以倒序、并行、交叉等其他顺序执行，而且，在上述步骤的基础上，本领域技术人员也可以再加入其他步骤，这些明显变型或等同替换的方式也应包含在本公开的保护范围之内，在此不再赘述。
