参阅图1，为本发明一优选实施例中滤镜切换方法的流程示意图。该实施例中，滤镜切换方法具体包括以下步骤：
S100：于所述智能终端内创建一空白滤镜
为了实现滤镜的无卡顿使用与切换，需要使用空白滤镜实现滤镜的初始化功能，需要创建一空白滤镜。由于使用相机以及处理图片时均有可以使用滤镜，因此，空白滤镜的应用对象既包括智能终端内的相机捕捉的图像，也包括已存储在智能终端内的图片。当空白滤镜应用至智能终端内的相机捕捉的图像或智能终端内的图片上时，空白滤镜不改变图像或图片的参数，保持所述图像或图片的原始参数不变，图像或图片的原始参数包括像素大小、每一像素点的红绿蓝值，即RGB值等参数。
S200：检测所述智能终端内的相机是否正在启动或所述智能终端内的图片是否正被调用
由于使用滤镜的卡顿一般出现在启动相机后第一次使用滤镜以及打开图片第一次使用滤镜时，也即从未使用滤镜状态到使用滤镜状态会发生卡顿，因此，在启动相机时以及调用图片时需要将空白滤镜应用至智能终端内的相机捕捉的图像或智能终端内的图片上，通过在用户未使用滤镜前使用空白滤镜实现对滤镜的初始化，后续使用滤镜时只需执行相应的图像处理操作即可，从而消除卡顿现象。因此，需要对相机是否正在启动或 图片是否正被调用进行检测，从而决定是否应用空白滤镜以及空白滤镜的应用对象是相机捕捉的图像还是智能终端内的图片。
S300：当所述智能终端内的相机正在启动或所述智能终端内的图片正被调用时，将所述空白滤镜应用至所述相机捕捉的图像上或所述图片上
检测智能终端内的相机是否启动以及图片是否被调用后，需要根据检测结果确定是否应用空白滤镜以及空白滤镜的应用对象。当检测到智能终端内的相机正在启动时，将调用空白滤镜程序，将空白滤镜应用到相机所捕捉的图像上；当检测到智能终端内的图片正被调用时，调用空白滤镜程序，将空白滤镜应用到智能终端内被调用的图片上。
S400：检测除所述空白滤镜外的其他滤镜是否被启用，当除所述空白滤镜外的其他滤镜被启用时，将所述空白滤镜切换为所述被启用的其他滤镜
由于已经将空白滤镜应用至相机捕捉的图像上或被调用的图片上，因此，此时用户看到的相机捕捉的图像或被调用的图片为带空白滤镜的图像或图片。相机启动或智能终端内的图片被调用后，用户有可能使用其他滤镜，为保证用户使用其他滤镜时无卡顿，需要实时监测除空白滤镜外的其他滤镜是否被启用，当检测到其他滤镜被启用时，需要将空白滤镜切换为被启用的其他滤镜。切换时只需执行其他滤镜对应的滤镜程序中的图像处理操作即可，无需再次初始化，从而节省了运行时间，解决卡顿问题。
具有上述配置后，在使用滤镜时，用户不会看到卡顿现象，从而实现流畅切换滤镜的效果。
参阅图2，在一优选实施例中，于所述智能空间内创建空白滤镜的方法，具体包括有：
S101：将所述智能终端内的相机捕捉的图像或所述智能终端内的图片复制，并缓存，形成第一副本图像或第一副本图片
在进行滤镜操作时，实质上是对目标对象的副本进行操作，因此对智能终端内的相机捕捉的图像或智能终端内的图片进行图像处理操作前，需要获取相机捕捉的图像或智能终端内的图片的副本，因此，首先需要复制相机捕捉的图像或智能终端内的图片，并进行缓存操作，将其临时存储在缓冲器中，形成第一副本图像或者第一副本图片。
S102：获取所述第一副本图像或第一副本图片的参数信息，参数信息包括图像或图片的像素、分辨率、灰度值、亮度、每一像素点的红绿蓝值等信息中的一种或多种
获取第一副本图像或者第一副本图片后，需要对第一副本图像或者第一副本图片进行不改变图片或图像参数的图像处理，因此，需要获取所述第一副本图像或第一副本图片的参数信息，参数信息应包括图像或图片的像素、分辨率、灰度值、亮度、每一像素 点的RGB值等信息中的一种或多种。
S103：保持所述第一副本图像或第一副本图片的参数信息不变，形成第二副本图像或第二副本图片
获取所述第一副本图像或第一副本图片的参数信息后，由于空白滤镜不改变图像或图片的原始参数，因此，应保持所述第一副本图像或第一副本图片的参数信息不变。如，参数信息为每一像素点的RGB值时，可对每一像素点的红绿蓝值进行减0或加0操作，相当于不更改红绿蓝值，除此之外，将获取的红绿蓝值都乘以或除以1的操作也是不更改红绿蓝值的操作。事实上，所有不更改图像或图片的原始参数的操作都是可以的，参数信息为像素大小、分辨率大小、亮度、灰度值时，对各参数信息的值进行乘以1或除以1的操作也可以，甚至在获取第一副本图像或第一副本图片后不进行操作也可以。此时获取的第二副本图像或第二副本图片即为经空白滤镜应用后的图像或图片。
参阅图3，在一优选实施例中，检测所述智能终端内的相机是否正在启动或所述智能终端内的图片是否被正调用的步骤可具体包括：
S201：获取第一程序与第二程序，其中第一程序为所述相机的启动程序，第二程序为所述智能终端内的图片调用程序
为检测所述智能终端内的相机是否正在启动或所述智能终端内的图片是否被正调用，需要检测第一程序即相应的相机程序以及第二程序即图片调用程序是否正被调用，因此，需要获取相机启动程序以及图片调用程序的程序名，或给相机程序以及图片调用程序设定相应触发标志，当程序被触发时，相应的触发标志为true。
S202：当所述第一程序被调用时，返回第一参数
当检测到智能终端内第一程序的程序名被调用或相应的触发标志为true时，第一程序被调用，因此，相机正在启动，向智能终端返回第一参数，第一参数为相机启动的标志。
S203：当所述第二程序被调用时，返回第二参数，并读取所述第二程序内的图片参数
当检测到智能终端内第二程序的程序名被调用或相应的触发标志为true时，第二程序被调用，因此，某一图片正被调用，向智能终端返回第二参数，第二参数为图片被调用的标志。同时，为明确被调用的图片为哪一图片，需要读取第二程序即图片调用程序中调用的图片参数，从而确定被调用的图片。
参阅图4，在一优选实施例中，当所述智能终端内的相机启动或图片被调用时，将所 述空白滤镜应用至所述相机捕捉的图像上或所述图片上的步骤具体包括：
S301：接收所述智能终端返回的参数
在检测智能终端内的相机是否正在启动或智能终端内的图片是否被正调用后，需要接收检测结果，也即智能终端返回的参数，包括第一参数与第二参数，也包括未返回参数，第一参数为智能终端内相机启动的标志，第二参数为图片被调用的标志，未返回参数即并接收到参数并一定不意味着没有参数返回，与设置的参数情况相关，例如，以第一参数或第二参数的true代表相机正在启动或图片正被调用，则第一参数与第二参数均为false时，即为未返回参数；若以存在第一参数或第二参数而不论参数的数值代表相机正在启动或图片正被调用，则没有接收到第一参数与第二参数即认为未返回参数。其中接收第二参数时，也应接收同时返回的图片参数。
S302：当所述智能终端返回的参数为第一参数时，将所述空白滤镜应用至所述相机捕捉的图像上
当接收到智能终端返回的参数为第一参数时，则认为智能终端内相机正在启动，此时需要执行空白滤镜对应的代码程序，将空白滤镜应用至相机捕捉的图像上，通过这一操作，将滤镜初始化的工作提前，而不改变图像的参数，因此用户并不知道系统已经执行此操作，而在用户第一次应用改变图像参数的滤镜时，该图像已经不是第一次使用滤镜，不会出现卡顿，而在用户看来，其第一次使用滤镜就没有出现卡顿，后续使用同样如此，因此，实现了滤镜切换与使用的流畅性。
S303：当所述智能终端返回的参数为第二参数时，将所述空白滤镜应用至所述图片参数对应的图片上
当接收到智能终端返回的参数为第二参数时，则认为智能终端内图片正在调用，此时需要执行空白滤镜对应的代码程序，同时，需要读取图片调用程序中的图片参数，确定被调用的图片，从而将空白滤镜应用至被调用的图片上，通过这一操作，将滤镜初始化的工作提前，而不改变图片的参数，因此用户并不知道系统已经执行此操作，而在用户第一次应用改变图片参数的滤镜时，该图片已经不是第一次使用滤镜，不会出现卡顿，而在用户看来，其第一次使用滤镜就没有出现卡顿，后续使用同样如此，因此，实现了滤镜切换与使用的流畅性。
参阅图5，在一优选实施例中，检测除所述空白滤镜外的其他滤镜是否被启用，当除所述空白滤镜外的其他滤镜被启用时，将所述空白滤镜切换为所述被启用的其他滤镜的步骤具体包括有：
S401：获取所述智能终端内除所述空白滤镜外的其他滤镜对应的滤镜程序
为了实现滤镜程序切换的流畅性，需要在用户使用滤镜时执行相应的切换操作，因此，需要对用户使用滤镜功能进行监测，首先需要获取所述智能终端内除所述空白滤镜外的其他滤镜对应的滤镜程序，其他滤镜对应的滤镜程序程序名或相应的触发标志均可，当检测到某一滤镜程序的程序名被调用或相应的触发标志为true时，认为该程序被调用。
S402：当所述滤镜程序中的至少一个被调用时，从所述相机捕捉的图像上或所述图片上删除所述空白滤镜
获取智能终端内除所述空白滤镜外的其他滤镜对应的滤镜程序后，对其进行监测，当当检测到某一滤镜程序的程序名被调用或相应的触发标志为true时，该程序被调用，此时用户需要使用具有图像处理功能的滤镜，因此，需要删除已经使用的空白滤镜，即删除空白滤镜进行的图像处理操作，事实上，由于空白滤镜进行的图像处理操作并不改变图像或图片的原始参数，因此，此处删除操作也可不执行。删除的方法既可以通过执行与滤镜程序中图像处理操作相反的操作，即通过逆操作进行还原，也可以在进行滤镜操作时保存两个副本，在其中一个副本上进行图像处理操作，当需要删除滤镜时，直接删除进行图像处理操作的该副本，并调取未进行图像处理操作的另一副本。
S403：执行被调用的所述滤镜程序，将被调用的所述滤镜程序对应的所述其他滤镜应用至所述相机捕捉的图像上或所述图片上
删除空白滤镜后，需要将用户使用的滤镜应用至相机捕捉的图像上或智能终端内的图片上，此时，执行被调用的滤镜程序，将被调用的滤镜程序对应的滤镜应用至相机捕捉的图像上或所述图片上。在执行被调用的滤镜程序时，只需执行该被调用的滤镜对应的图像处理操作即可，而不需要进行初始化等前序操作，因此，实现了滤镜的流畅切换，不会出现卡顿现象。
参阅图6，为符合本发明一优选实施例中基于智能终端的滤镜切换系统，其具体包括以下部件：
空白滤镜创建模块，为了实现滤镜的无卡顿使用与切换，需要使用空白滤镜实现滤镜的初始化功能，需要创建一空白滤镜。由于使用相机以及处理图片时均有可以使用滤镜，因此，空白滤镜的应用对象既包括智能终端内的相机捕捉的图像，也包括已存储在智能终端内的图片。当空白滤镜应用至智能终端内的相机捕捉的图像或智能终端内的图片上时，空白滤镜不改变图像或图片的参数，保持所述图像或图片的原始参数不变，图像或图片的原始参数包括像素大小、每一像素点的红绿蓝值，即RGB值等参数。

执行单元，与所述参数信息获取单元连接，获取所述第一副本图像或第一副本图片 的参数信息后，由于空白滤镜不改变图像或图片的原始参数，因此，应保持所述第一副本图像或第一副本图片的参数信息不变。如，参数信息为每一像素点的RGB值时，可对每一像素点的红绿蓝值进行减0或加0操作，相当于不更改红绿蓝值，除此之外，将获取的红绿蓝值都乘以或除以1的操作也是不更改红绿蓝值的操作。事实上，所有不更改图像或图片的原始参数的操作都是可以的，参数信息为像素大小、分辨率大小、亮度、灰度值时，对各参数信息的值进行乘以1或除以1的操作也可以，甚至在获取第一副本图像或第一副本图片后不进行操作也可以。此时获取的第二副本图像或第二副本图片即为经空白滤镜应用后的图像或图片。
