技术领域
本申请涉及终端领域，具体地，涉及一种拍照处理方法和电子设备。
背景技术
随着电子设备中拍摄功能的发展，相机应用程序在电子设备中的应用越来越广泛。目前，在电子设备检测到多次连续拍照操作的情况下，电子设备通常会最后处理拍摄时间最晚的数据包；但是，在拍照结束后，用户通常会通过点击拍摄时间最晚的缩略图像对实际的拍摄图像进行查看；由于电子设备通常在最后处理拍摄时间最晚的拍摄图像，因此电子设备需要在一段时长后才能在图库应用程序中显示拍摄时间最晚的拍摄图像；因此，目前在用户点击拍摄时间最晚的缩略图像后，电子设备无法快速地显示实际的拍摄图像；从而导致用户的等待时长较长，拍摄体验感较差。
因此，在电子设备检测到点击缩略图像的情况下，如何快速地显示实际的拍摄图像成为一个亟需解决的问题。
发明内容
本申请提供了一种拍照处理方法和电子设备，在电子设备检测到点击缩略图像的情况下，能够在一定程度上快速地显示拍摄图像，提高拍摄体验。

示例性地，指纹传感器180H用于采集指纹。电子设备100可以利用采集的指纹特性实现解锁、访问应用锁、拍照和接听来电等功能。
示例性地，触摸传感器180K，也称为触控器件。触摸传感器180K可以设置于显示屏194，由触摸传感器180K与显示屏194组成触摸屏，触摸屏也称为触控屏。触摸传感器180K用于检测作用于其上或其附近的触摸操作。触摸传感器180K可以将检测到的触摸操作传递给应用处理器，以确定触摸事件类型。可以通过显示屏194提供与触摸操作相关的视觉输出。在另一些实施例中，触摸传感器180K也可以设置于电子设备100的表面，并且与显示屏194设置于不同的位置。
目前，电子设备通常是按照先采集先处理的方式对图像传感器采集的数据包进行图像处理；由于电子设备按照先采集先处理的方式对数据包进行处理，则拍摄时间最晚的图像电子设备通常在最后处理；但是，在用户结束拍照操作后，用户通常会点击缩略图查看实际的拍摄图像，此时缩略图像通常为拍摄时间最晚的缩略图像；由于电子设备通常在最后处理拍摄时间最晚的拍摄图像，因此电子设备需要一段时长后才能在图库应用程序中显示拍摄时间最晚的拍摄图像；因此，目前在用户点击缩略图像后，存在图库应用程序中无法快速地显示拍摄时间最晚的拍摄图像的问题；从而导致用户的等待时长较长，拍摄体验感较差。
示例性地，如图2所示，以电子设备检测到3次快速连续拍摄的操作进行举例说明；在电子设备检测到3次快速连续拍摄的操作的情况下，电子设备检测到拍照操作的顺序为：第一次拍照操作、第二次拍照操作与第三次拍照操作；由于电子设备按照先采集先处理的方式对采集的图像进行处理；其中，第一次拍摄操作对应电子设备采集数据包1，第二次拍照操作对应电子设备采集数据包2，第三次拍照操作对应电子设备采集数据包3；电子设备处理数据包的顺序为：数据包1、数据包2与数据包3；电子设备检测到点击缩略图像后显示拍摄图像(例如，图库应用程序显示拍摄图像)的顺序为按照时间的逆顺序进行显示，可以理解为电子设备显示拍摄图像的顺序为：第三拍摄图像、第二拍摄图像与第一拍摄图像；由于一次拍摄可以采集一帧或者多帧图像，通过对一帧或者多帧图像的处理生成一次拍摄的拍摄图像；在电子设备检测到第三次拍照操作后，电子设备可能还在处理第一次拍摄的图像或者第二次拍摄的图像；此时，电子设备无法在用户点击第三次拍摄的缩略图像之后，快速地显示第三次拍摄的拍摄图像；导致用户的等待时长较长，拍摄体验感较差。
例如，假设电子设备采集一个数据包的时长为0.1秒；电子设备处理一个数据包所需时长为3秒，即电子设备生成一张拍摄图像所需的时长为3秒；若电子设备检测到快速地3次连续拍照操作，则电子设备需要9秒才能生成第三拍摄图像；因此，用户在完成拍照操作，点击第三拍摄图像的缩略图像后，电子设备还需要一段时长后才能显示第三拍摄图像；导致用户的等待时长较长，拍摄体验感较差。
示例性地，电子设备运行相机应用程序后，显示预览界面201，如图3中的(a) 所示；预览界面201中包括预览图像、拍照控件202与缩略图显示控件203，其中，缩略图显示控件203中显示的图像为上一次拍照的缩略图像；电子设备检测到多次快速连续拍摄的操作；例如，电子设备检测到点击拍照控件202的操作，如图3中的(b)所示；在电子设备检测到点击拍照控件202的操作之后，电子设备检测到弹起拍照控件202的操作，显示显示界面204，如图3中的(c)所示；在电子设备检测到弹起拍照控件202的操作之后，电子设备检测到点击拍照控件202的操作，如图3中的(d)所示；在电子设备检测到点击拍照控件202的操作之后，电子设备检测到弹起拍照控件202的操作，显示显示界面205，如图4中的(a)所示；在电子设备检测到弹起拍照控件202的操作之后，电子设备检测到点击缩略图显示控件203的操作，如图4中的(b)所示；在电子设备检测到点击缩略图显示控件203的操作之后，电子设备可以显示显示界面206，显示界面206中包括第二次拍照操作采集的图像；由于目前电子设备按照先采集先处理的方式对数据包进行图像处理，因此在电子设备检测到点击缩略图显示控件203的操作时，可能正在处理第一次拍照操作采集的第一拍摄图像还未处理第二次拍照操作采集的数据包；因此，此时显示的第二次拍照的图像为通过对第二次拍照的缩略图像进行缩放处理得到的图像，并非第二次拍照的真实图像；例如，如图4中的(c)所示，显示界面206中显示的图像中包括图像区域207，图像区域207中细节信息较差；在一定时长之后，电子设备生成第二次拍照的拍摄图像，显示显示界面208，显示界面208中包括第二次拍照的拍摄图像，即第二次拍照摄的真实图像；第二次拍照图像的真实图像中包括图像区域209；图像区域209中的细节信息优于图像区域207中的细节信息，如图4中的(d)所示。
需要说明的是，用户在完成拍照操作后通常会点击缩略图显示控件203查看拍摄图像；在点击缩略图显示控件203之后，用户希望能够快速地在图库应用程序中显示拍摄图像；若电子设备按照目前的先采集先处理的方式(例如，按照采集时刻从早到晚的顺序)对图像进行处理，则电子设备显示无法在检测到弹起拍照控件后快速显示拍摄图像，导致用户的拍摄等待时长较长，拍摄体验较差。
还应理解，电子设备检测到一次点击拍照控件的操作与一次弹起拍照控件的操作可以是看作是检测到一次拍照操作；多次快速连续拍摄的操作可以是指电子设备在较短的时间内检测到多次拍照操作；例如，可以是在较短的时间内电子设备检测到3次拍照操作，3次拍照操作包括第一次点击拍照控件的操作与第一次弹起拍照控件的操作；第二次点击拍照控件的操作与第二次弹起拍照控件的操作；第三次点击拍照控件的操作与第三次弹起拍照控件的操作。
有鉴于此，本申请的实施例提供了一种拍照处理方法和电子设备；在本申请的实施例中，电子设备通过按照采集时刻从早到晚的顺序采对采集的图像数据包进行图像处理，生成拍摄图像，从而在一定程度上能够缩短电子设备检测到点击缩略图像的操作与显示拍摄图像之间的时长；可以理解为，电子设备在处理连续拍照操作中第一次拍照操作的数据包之后，可以选取存储的图像数据队列中逆序方向的第一个数据包进行图像处理，即获取拍摄时间最晚的数据包进行图像处理；从而确保电子设备能够快速处理拍摄时间靠后的拍摄图像，使得电子设备检测到点击缩略图像的操作之后能够快速地显示拍摄图像；在一定程度上能够缩短用户等待拍摄图像的时长，提高用户的拍摄体验。

示例性地，第一算法为Raw颜色空间的算法；Raw颜色空间的算法可以包括但不限于：黑电平矫正处理(Black Level Correction，BLC)、镜头阴影校正(Lens Shading Correction，LSC)等算法。
其中，黑电平矫正处理用于对黑电平进行校正处理，黑电平是指在经过一定校准的显示装置上，没有一行光亮输出的视频信号电平；进行黑电平校正的原因在于：一方面由于图像传感器存在暗电流，导致在没有光照的情况下像素也存在电压输出的问题；另一方面，由于图像传感器进行模数转换时精度不够。镜头阴影校正(Lens Shading Correction，LSC)用于消除由于镜头光学系统原因造成的图像四周颜色以及亮度与图像中心不一致的问题。

示例性地，对于电子设备检测到一次拍照操作的场景中，在该场景中后处理队列中只包括数据包1；电子设备可以先对数据包1进行图像处理，接着采用上述先采集后处理的方式对数据包进行图像处理；在后处理队列中，由于后处理队列中只包括数据包1，因此在对数据包1进行图像处理后，电子设备未检测到其他数据包，则可以结束图像处理流程。
示例性地，对于电子设备检测到连续两次拍照操作的场景中，在该场景中后处理队列中只包括数据包1与数据包2；电子设备可以先对数据包1进行图像处理，接着采用上述先采集后处理的方式对数据包进行图像处理；在后处理队列中，由于后处理队列中只包括数据包1与数据包2，因此在对数据包1进行图像处理后，按照第一方向的相反方向，选取当前后处理队列中的第一个数据包，即对数据包2进行图像处理。
图7是本申请实施例提供的一种拍照处理方法的示意性流程图。该方法400可以由图1所示的电子设备执行；该方法400包括S401至S412，下面分别对S401至S412进行详细的描述。

应理解，如图7所示，存储方向可以为第一方向，第一方向是指由右向左的方向；则第一方向的相反方向可以是指第一方向的逆序方向；若第一方向为由右向左的方向，则第一方向的逆序方向可以是指由左向右的方向；此外，若电子设备处理一个数据包，则该数据包可以看作是移出后处理队列；可以理解为，后处理队列中存储的数据包均为未处理的数据包；按照存储方向的相反方向选取的第一个数据包则是指拍照操作的时刻最晚的数据包。
示例性地，如图7所示，由于在第一流程405中电子设备对第一数据包进行图像处理；因此，此时后处理队列中包括的未处理的数据包为数据包2与数据包3，按照存储的逆序方向选取后处理队列中的数据包，则获取数据包3。
可选地，在处理第一数据包中的结束帧时，电子设备可以按照存储的逆序方向，选取当前后处理队列中的第一个数据包。
示例性地，如图9中的(b)所示，在电子设备处理第一数据包中的结束帧时(例如，数据包1中的结束帧)，当前后处理队列中包括数据包2与数据包3；此时，电子设备可以选取当前的后处理队列中逆序方向的第一个数据包，即选取数据包3；并对数据包3进行图像处理生成拍摄图像。
在本申请的实施例中，电子设备通过采用先采集后处理的方式对采集的图像数据包进行图像处理，生成拍摄图像，从而在一定程度上能够缩短电子设备检测到点击缩略图像的操作与显示拍摄图像之间的时长；可以理解为，电子设备在处理连续拍照操作中第一次拍照操作的数据包之后，可以选取存储的图像数据队列中逆序方向的第一个数据包进行图像处理，即获取拍摄时间最晚的数据包进行图像处理；从而确保电子设备能够快速处理拍摄时间靠后的拍摄图像，使得电子设备检测到点击缩略图像的操作之后能够快速地显示拍摄图像；在一定程度上能够缩短用户等待拍摄图像的时长，提高用户的拍摄体验。
需要说明的是，在本申请的实施例中，方法400可以适用于连续拍摄的场景中；因此，电子设备可以多次检测到拍照操作；在执行S440的同时电子设备还可以检测到其他拍照操作，基于其他拍照操作后处理队列中会不断存入新的数据包，如图9中的(b)所示；在本申请的实施例中，电子设备在处理到第一数据包之后，可以按照先采集后处理的方式顺序对后处理队列中的数据包进行图像处理；而是在后处理队列中选取当前的最后一个数据包进行处理，从而能够在一定程度上缩短用户的拍摄等待时长。
可选地，在处理到第一数据包中的结束帧时，根据逆序处理方式在后处理队列中选取第一个起始帧，获取最后一个数据包。
示例性地，如图10所示，以一次连续拍照操作包括3次拍照操作进行举例说明；其中，按照从前到后的时间顺序电子设备分别检测到第一拍照操作、第二拍照操作与第三拍照操作；第一拍照操作对应的数据包中包括：起始帧、图像帧1、图像帧2、图像帧3与结束帧；第二拍照操作对应的数据包中包括：起始帧、图像帧3、图像帧4、图像帧5与结束帧；第三拍照操作对应的数据包中包括：起始帧、图像帧7、图像帧8、图像帧9与结束帧为后处理队列中存储的第三次拍照操作的数据；在电子设备检测到第一拍照操作之后，在第一时刻选帧模块通过指示信息1指示第一拍照操作的数据包从起始帧开始出队(例 如，开始从后处理队列中获取数据)；在第二时刻，选帧模块通过指示信息2指示第一拍照操作的数据包结束出队(例如，停止从后处理队列中获取数据)；在第三时刻，选帧模块逆向遍历整个后处理处理队列，找到第一个起始帧的位置，即第三拍照操作的起始帧；通过指示信息3指示第三拍照操作的数据包从起始帧开始出队；在第四时刻，选帧模块通过指示信息4指示第三拍照操作的数据包结束出队；在第五时刻，选帧模块逆向遍历整个后处理处理队列，找到第一个起始帧的位置，即第二次拍摄的起始帧；通过指示信息5指示第二拍照操作的数据包从起始帧开始出队；在第六时刻，选帧模块通过指示信息6指示第二拍照操作的数据包结束出队；选帧模块从后处理队列中选取数据的顺序为：第一拍照操作的数据包、第三拍照操作的数据包与第二拍照操作的数据包。
S408、对选取的数据包进行图像处理，生成第二拍摄图像。
可选地，如图7所示，按照存储方向的相反方向，选取当前后处理队列中的第一个数据包为数据包3；对数据包3进行图像处理，生成第二拍摄图像。
应理解，数据包3对应第三拍照操作，即拍照操作时刻最晚的拍照操作；第二拍摄图像为根据第三拍照操作生成的拍摄图像。
可选地，图像处理的实现方式可以参见上述S4051的相关描述，此处不再赘述。
S409、检测到点击缩略图像的操作(第二操作的一个示例)。
应理解，由于按拍照时刻的从早到晚的顺序电子设备分别检测到第一拍照操作、第二拍照操作与第三拍照操作；其中，第三拍照操作为拍照时间最晚的拍照操作，因此若在第三拍照操作之后在一段时长内，电子设备未检测到拍照操作，则电子设备的拍摄界面中显示的缩略图像为第三拍照操作的缩略图像；可以理解为，电子设备拍摄界面中通常显示拍照操作的时刻最晚的缩略图像；在电子设备检测到点击第三拍照操作的缩略图像的操作之后，电子设备可以显示存储在图库应用程序中的拍摄图像，即第二拍摄图像。
示例性地，检测到点击第三拍照操作的缩略图像的操作可以如17中的(f)所示。
S410、显示第二拍摄图像。
可选地，显示第二拍摄图像可以是在图库应用程序中显示第三拍照操作的拍摄图像，即第三拍照操作的实际的拍摄图像。
应理解，在用户结束拍照操作后，用户通常通过点击缩略图像对拍摄图像进行查看；可以理解为，用户通过点击缩略图像查看图库应用程序中存储的实际的拍摄图像。
示例性地，如假设电子设备处理一个数据包的时长为3秒，即电子设备生成一张拍摄图像的时长为3秒；采集一个数据包的时长为1秒；采用现有的方式生成拍照时刻最晚的拍照图像；例如，按照如图2所示的先采集先处理的方式生成拍摄图像，则电子设备在第9秒时才能生成第二拍摄图像；而基于本申请的实施例提供的拍照处理方法，在电子设备生成第一拍摄图像之后，则电子设备可以生成第二拍摄图像；可以理解为，基于本申请实施例提供的拍摄处理方式，如图7所示则电子设备在第6秒时可以生成第二拍摄图像；因此，在本申请的实施例中，在电子设备检测到用户点击第二拍摄图像的缩略图像时，可以快速地显示第二拍摄图像；从而在一定程度上缩短用户的等待时长，提高用户的拍摄体验。
在本申请的实施例中，电子设备通过采用先采集后处理的方式对采集的图像数据包进行图像处理，生成拍摄图像，从而在一定程度上能够缩短电子设备检测到点击缩略图像的操作与显示拍摄图像之间的时长；可以理解为，电子设备在处理连续拍照操作中第一次拍 照操作的数据包之后，可以选取存储的图像数据队列中逆序方向的第一个数据包进行图像处理，即获取拍摄时间最晚的数据包进行图像处理；从而确保电子设备能够快速处理拍摄时间靠后的拍摄图像，使得电子设备检测到点击缩略图像的操作之后能够快速地显示拍摄图像；在一定程度上能够缩短用户等待拍摄图像的时长，提高用户的拍摄体验。
S411、按照存储方向的相反方向，选取当前后处理队列中的第一个数据包。
应理解，如图7所示，存储方向可以为第一方向，第一方向是指由右向左的方向；则第一方向的相反方向(例如，逆序方向)是指第一方向的相反方向；若第一方向为由右向左的方向，则第一方向的逆序方向可以是指由左向右的方向；此外，若电子设备处理一个数据包，则该数据包可以看作是移出后处理队列；可以理解为，后处理队列中存储的数据包均为未处理的数据包；按照存储的逆序方向选取的第一个数据包则是指拍照操作的时刻最晚的数据包。
示例性地，如图7所示，由于在第一流程405中电子设备对第一数据包进行图像处理，S408中对数据包3进行图像处理；因此，此时后处理队列中包括的未处理的数据包为数据包3，按照存储方向的相反方向选取后处理队列中的第一个数据包，则获取数据包2。
S412、对选取的数据包进行图像处理，生成第三拍摄图像。
可选地，如图7所示，按照存储方向的相反方向，选取当前后处理队列中的第一个数据包为数据包2；对数据包2进行图像处理，生成第三拍摄图像。
应理解，数据包2对应第二拍照操作，电子设备检测到第二拍摄操作的时刻位于检测到第一拍摄操作的时刻与检测到第二拍摄操作的时刻之间。
可选地，图像处理的实现方式可以参见上述S4051的相关描述，此处不再赘述。
在本申请的实施例中，电子设备通过采用先采集后处理的方式对采集的图像数据包进行图像处理，生成拍摄图像，从而在一定程度上能够缩短电子设备检测到点击缩略图像的操作与显示拍摄图像之间的时长；可以理解为，电子设备在处理连续拍照操作中第一次拍照操作的数据包之后，可以选取存储的图像数据队列中逆序方向的第一个数据包进行图像处理，即获取拍摄时间最晚的数据包进行图像处理；从而确保电子设备能够快速处理拍摄时间靠后的拍摄图像，使得电子设备检测到点击缩略图像的操作之后能够快速地显示拍摄图像；在一定程度上能够缩短用户等待拍摄图像的时长，提高用户的拍摄体验。
可选地，图7是以电子设备检测到连续3次拍照操作进行举例说明；本申请实施例提供的拍照处理方法同样适用于电子设备检测到一次拍照操作与连续的两次拍照操作的场景。
示例性地，对于电子设备检测到一次拍照操作的场景中，在该场景中后处理队列中只包括数据包1；电子设备可以先对数据包1进行图像处理，接着采用上述先采集后处理的方式对数据包进行图像处理；在后处理队列中，由于后处理队列中只包括数据包1，因此在对数据包1进行图像处理后，电子设备未检测到其他数据包，则可以结束图像处理流程。
示例性地，对于电子设备检测到连续两次拍照操作的场景中，在该场景中后处理队列中只包括数据包1与数据包2；电子设备可以先对数据包1进行图像处理，接着采用上述先采集后处理的方式对数据包进行图像处理；在后处理队列中，由于后处理队列中只包括数据包1与数据包2，因此在对数据包1进行图像处理后，按照存储方向的相反方向，选取当前后处理队列中的第一个数据包，即对数据包2进行图像处理。
可选地，下面结合图11至图16对电子设备检测到连续三次以上的拍照操作进行举例说明。
示例一
可选地，在电子设备检测到一次连续拍照操作时，电子设备可以按照后处理队列中数据包的存储方向的相反方向在后处理队列中选取当前的第一个数据包进行图像处理，生成拍摄图像；从而确保电子设备能够快速处理拍摄时间靠后的拍摄图像，使得电子设备检测到连续拍照操作之后能够快速地生成拍摄图像；在一定程度上能够缩短用户等待拍摄图像的时长，提高用户的拍摄体验。
例如，可以先处理后处理队列中连续拍照操作中第一次拍照操作的数据包；在处理连续拍照操作中第一次拍照操作的数据包之后，处理连续拍照操作中时间最晚的数据包；再依次按照时间顺序从后向前处理不同拍摄操作的数据包；确保电子设备能够快速处理拍摄时间靠后的拍摄图像，使得电子设备检测到连续拍照操作之后能够快速地生成拍摄图像；在一定程度上能够缩短用户等待拍摄图像的时长，提高用户的拍摄体验。
示例性地，如图11所示，以连续拍照操作包括5次拍照操作进行举例说明；5次拍摄操作对应生成5张拍摄图像，分别为拍摄图像1、拍摄图像2、拍摄图像3、拍摄图像4与拍摄图像5；第一次拍摄操作电子设备采集的数据包为数据包1；第二次拍摄操作电子设备采集的数据包为数据包2；第三次拍摄操作电子设备采集的数据包为数据包3；第四次拍摄操作电子设备采集的数据包为数据包4；第五次拍摄操作电子设备采集的数据包为数据包5；如图12所示，假设电子设备处理一个数据包所需的时长为3秒；采集一个数据包的时长为0.1秒，即1秒可以采集10次拍照操作的数据；则在第一时刻(例如，第0.1秒)，电子设备采集数据包1；并对数据包1进行图像处理，生成拍摄图像1；在第3.1秒电子设备处理完数据包1；此时，由于电子设备采集一次拍照操作的图像数据为0.1秒，电子设备检测到5次拍照操作；则电子设备在第0.5秒采集5个数据包；在第二时刻(例如，第3.1秒)，电子设备按照逆序方向在当前的后处理队列中获取第一个数据包，即数据包5；电子设备对数据包5进行图像处理，生成拍摄图像5；重复执行上述操作，在生成拍摄图像5之后，电子设备按照逆序方向在当前的后处理队列中获取第一个数据包，即数据包4；电子设备对数据包4进行图像处理，生成拍摄图像4；在生成拍摄图像4之后，电子设备按照逆序方向在当前的后处理队列中获取第一个数据包，即数据包3；电子设备对数据包3进行图像处理，生成拍摄图像3；在生成拍摄图像3之后，电子设备按照逆序方向在当前的后处理队列中获取第一个数据包，即数据包2；电子设备对数据包2进行图像处理，生成拍摄图像2；此时，电子设备生成拍摄图像1、拍摄图像2、拍摄图像3、拍摄图像4与拍摄图像5。
需要说明的是，获取后处理队列一个数据包，对数据包进行图像处理可以看作是该数据包移除后处理队列；由于电子设备在对后处理队列中数据包进行处理的同时，电子设备还可能采集基于检测到的拍照操作采集新的数据包；因此，后处理队列中的数据包可以看作是处于实时更新状态，即有新写入的数据包同时也有移出的数据包；在处理至前一个数据包的包尾时，可以选取当前后处理队列中按照逆序方向的第一个数据包；其中，逆序顺序可以理解为与数据包存储至后处理队列的方向相反。
可选地，电子设备按照逆序方向在当前的后处理队列中获取第一个数据包的实现方式 可以参见图9与图10的相关描述，此处不再赘述。
示例二
可选地，在电子设备检测到至少连续拍照操作时，电子设备可以按照后处理队列中存储数据包的相反方向在后处理队列中选取当前的第一个数据包进行图像处理，生成拍摄图像；从而确保电子设备能够快速处理拍摄时间靠后的拍摄图像，使得电子设备检测到连续拍照操作之后能够快速地生成拍摄图像；在一定程度上能够缩短用户等待拍摄图像的时长，提高用户的拍摄体验。
情况一
例如，以电子设备检测到两次连续拍照操作进行举例说明，其中，第一次连续拍照操作包括5次拍照操作；例如，第一次连续拍照操作包括第一次拍照操作至第五次拍摄操作；第二次连续拍照操作包括2次拍照操作；例如，第二次连续拍照操作包括第六次拍照操作与第七次拍照操作；如图13所示，7次拍摄操作对应生成7张拍摄图像，分别为拍摄图像1、拍摄图像2、拍摄图像3、拍摄图像4、拍摄图像5、拍摄图像6与拍摄图像7；第一次拍摄操作电子设备采集的数据包为数据包1；第二次拍摄操作电子设备采集的数据包为数据包2；第三次拍摄操作电子设备采集的数据包为数据包3；第四次拍摄操作电子设备采集的数据包为数据包4；第五次拍摄操作电子设备采集的数据包为数据包5；第六次拍摄操作电子设备采集的数据包为数据包6；第七次拍摄操作电子设备采集的数据包为数据包7，如图14所示。
示例性地，如图13与图14所示，在第一时刻，电子设备在后处理队列中按照数据包的存储方向的相反方向(例如，逆序方向)获取第一个数据包进行图像处理；例如，在第一时刻电子设备获取数据包1进行图像处理，生成拍摄图像1；在电子设备对数据包1进行图像处理的同时，基于电子设备检测到的拍照操作，后处理队列中存储数据包2至数据包5；在第二时刻，电子设备处理至数据包1中的结束帧时，电子设备在后处理队列中按照数据包的存储方向的相反方向获取第一个数据包，即数据包5；电子设备对数据包5进行图像处理，生成拍摄图像5；在第三时刻，电子设备处理至数据包5中的结束帧时，电子设备在后处理队列中按照存储方向的相反方向获取第一个数据包，即数据包7；电子设备对数据包7进行图像处理，生成拍摄图像7；重复执行上述操作，在生成拍摄图像7之后，电子设备在后处理队列中按照数据包的存储方向的相反方向获取第一个数据包，即数据包6；电子设备对数据包6进行图像处理，生成拍摄图像6；在生成拍摄图像6之后，即电子设备处理至数据包6中的结束帧时，电子设备按照存储方向的相反方向在当前的后处理队列中获取第一个数据包，即数据包4；电子设备对数据包4进行图像处理，生成拍摄图像4；在生成拍摄图像4之后，电子设备在后处理队列中按照数据包的存储方向的相反方向在当前的后处理队列中获取第一个数据包，即数据包3；电子设备对数据包3进行图像处理，生成拍摄图像3；在生成拍摄图像3之后，电子设备在后处理队列中按照数据包的存储方向的相反方向获取第一个数据包，即数据包2；电子设备对数据包2进行图像处理，生成拍摄图像2；此时，电子设备生成拍摄图像1、拍摄图像2、拍摄图像3、拍摄图像4、拍摄图像5、拍摄图像6与拍摄图像7。
应理解，电子设备在处理当前数据包的结束帧时，电子设备在后处理队列中可以按照数据包的存储方向的相反方向获取第一个数据包；可以理解为，在电子设备处理至上一个 数据包的包尾时，电子设备可以从后处理队列中选取下一次处理的数据包；选取时按照拍摄时间从后向前的顺序进行选取；即电子设备优先选取拍摄时间最靠后的数据包。
可选地，电子设备按照逆序方向在当前的后处理队列中获取第一个数据包的实现方式可以参见图9与图10的相关描述，此处不再赘述。
情况二
例如，以电子设备检测到两次连续拍照操作进行举例说明，其中，第一次连续拍照操作包括5次拍照操作；例如，第一次连续拍照操作包括第一次拍照操作至第五次拍摄操作；第二次连续拍照操作包括2次拍照操作；例如，第二次连续拍照操作包括第六次拍照操作与第七次拍照操作；如图15所示，7次拍摄操作对应生成7张拍摄图像，分别为拍摄图像1、拍摄图像2、拍摄图像3、拍摄图像4、拍摄图像5、拍摄图像6与拍摄图像7；第一次拍摄操作电子设备采集的数据包为数据包1；第二次拍摄操作电子设备采集的数据包为数据包2；第三次拍摄操作电子设备采集的数据包为数据包3；第四次拍摄操作电子设备采集的数据包为数据包4；第五次拍摄操作电子设备采集的数据包为数据包5；第六次拍摄操作电子设备采集的数据包为数据包6；第七次拍摄操作电子设备采集的数据包为数据包7，如图16所示。
示例性地，如图15与图16所示，在第一时刻，电子设备在后处理队列中按照逆序方向获取第一个数据包进行图像处理；例如，在第一时刻电子设备获取数据包1进行图像处理，生成拍摄图像1；在电子设备对数据包1进行图像处理的同时，基于电子设备检测到的拍照操作，后处理队列中存储数据包2至数据包7；在第二时刻，电子设备处理至数据包1中的结束帧时，电子设备在后处理队列中按照逆序方向获取第一个数据包，即数据包7；电子设备对数据包7进行图像处理，生成拍摄图像7；重复执行上述操作，在生成拍摄图像7之后，电子设备按照逆序方向在当前的后处理队列中获取第一个数据包，即数据包6；电子设备对数据包6进行图像处理，生成拍摄图像6；在生成拍摄图像6之后，即电子设备处理至数据包6中的结束帧时，电子设备按照逆序方向在当前的后处理队列中获取第一个数据包，即数据包5；电子设备对数据包5进行图像处理，生成拍摄图像5；在生成拍摄图像5之后，电子设备按照逆序方向在当前的后处理队列中获取第一个数据包，即数据包4；电子设备对数据包4进行图像处理，生成拍摄图像4；在生成拍摄图像4之后，电子设备按照逆序方向在当前的后处理队列中获取第一个数据包，即数据包3；电子设备对数据包3进行图像处理，生成拍摄图像3；在生成拍摄图像3之后，电子设备按照逆序方向在当前的后处理队列中获取第一个数据包，即数据包2；电子设备对数据包2进行图像处理，生成拍摄图像2；此时，电子设备生成拍摄图像1、拍摄图像2、拍摄图像3、拍摄图像4、拍摄图像5、拍摄图像6与拍摄图像7。
可选地，电子设备按照逆序方向在当前的后处理队列中获取第一个数据包的实现方式可以参见图9与图10的相关描述，此处不再赘述。
需要说明的是，上述情况二与情况一的区别在于：在情况一中，电子设备处理数据包1之后，后处理队列中包括数据包2至数据包5，此时电子设备在后处理队列中按照数据包的存储方向的相反方向获取第一个数据包，即获取数据包5；在情况二中，电子设备处理数据包1之后，后处理队列中包括数据包2至数据包7，此时电子设备在后处理队列中按照数据包的存储方向的相反方向获取第一个数据包，即获取数据包7；存在上述情况的 原因在于电子设备在连续拍照操作时不同拍照操作的时间间隔可能存在差异；由于时间间隔存在差异，因此电子设备中后处理队列中存储的图像数据可能不同。
在本申请的实施例中，电子设备通过采用先采集后处理的方式对采集的图像数据包进行图像处理，生成拍摄图像，从而在一定程度上能够缩短电子设备检测到点击缩略图像的操作与显示拍摄图像之间的时长；可以理解为，电子设备在处理连续拍照操作中第一次拍照操作的数据包之后，可以选取存储的图像数据队列中逆序方向的第一个数据包进行图像处理，即获取拍摄时间最晚的数据包进行图像处理；从而确保电子设备能够快速处理拍摄时间靠后的拍摄图像，使得电子设备检测到点击缩略图像的操作之后能够快速地显示拍摄图像；在一定程度上能够缩短用户等待拍摄图像的时长，提高用户的拍摄体验。
下面结合图17至图20对适用于本申请实施例的界面示意图进行详细描述。
示例性地，电子设备运行相机应用程序后，显示预览界面501，如图17中的(a)所示；预览界面501中包括预览图像、拍照控件502与缩略图显示控件503，其中，缩略图显示控件503中显示的图像为上一次拍照的缩略图像；电子设备检测到多次快速连续拍摄的操作；例如，电子设备检测到点击拍照控件502的操作，如图17中的(b)所示；在电子设备检测到点击拍照控件502的操作之后，电子设备检测到弹起拍照控件502的操作，显示显示界面504，如图17中的(c)所示；在电子设备检测到弹起拍照控件502的操作之后，电子设备检测到点击拍照控件502的操作，如图17中的(d)所示；在电子设备检测到点击拍照控件502的操作之后，电子设备检测到弹起拍照控件502的操作，如图17中的(e)所示；在电子设备检测到弹起拍照控件502的操作之后，电子设备检测到点击缩略图显示控件503的操作，如图17中的(f)所示；在电子设备检测到点击缩略图显示控件503的操作之后，电子设备可以显示图库应用应用程序中的显示界面，如图18所示。
需要说明的是，结合图4中的(b)至图4中的(d)、图17中的(f)与图18可以看出，在本申请的实施例提供的拍照处理方法中，电子设备通过先采集后处理后的方法对连续拍照的数据包进行图像处理，可以在检测到点击缩略图像的操作时缩短生成拍摄图像的等待时长；可以理解为，电子设备可以优先处理拍摄时间最晚的数据包，从而在检测到电子设备点击缩略图显示控件后的等待时长，即可以在一定程序上缩短显示拍摄图像的等待时长；提高用户的拍摄体验。
下面结合图19与图20对电子设备中开启快速显示拍摄图像，即执行本申请实施例的拍照处理方法的界面示意图进行描述。

在本申请的实施例中，电子设备通过采用先采集后处理的方式对采集的图像数据包进行图像处理，生成拍摄图像，从而在一定程度上能够缩短电子设备检测到点击缩略图像的操作与显示拍摄图像之间的时长；可以理解为，电子设备在处理连续拍照操作中第一次拍照操作的数据包之后，可以选取存储的图像数据队列中逆序方向的第一个数据包进行图像处理，即获取拍摄时间最晚的数据包进行图像处理；从而确保电子设备能够快速处理拍摄时间靠后的拍摄图像，使得电子设备检测到点击缩略图像的操作之后能够快速地显示拍摄图像；在一定程度上能够缩短用户等待拍摄图像的时长，提高用户的拍摄体验。
