技术领域
本公开实施例涉及通信技术领域，尤其涉及一种摄像头切换方法及终端设备。
背景技术
随着终端技术的发展，终端设备的屏占比越来越高。例如，可以将终端设备的前置摄像头设置为伸缩摄像头，从而实现终端设备的全面屏设计。
通常，用户可以触发终端设备在前置摄像头和后置摄像头之间切换，以适应不同的应用场景。具体的，在终端设备的前置摄像头处于工作状态(此时前置摄像头从终端设备内部伸出)的情况下，如果用户需求使用后置摄像头，那么用户可以触发终端设备从前置摄像头切换到后置摄像头，即触发终端设备关闭前置摄像头并控制前置摄像头缩回到终端设备内部，且开启后置摄像头(即此时后置摄像头处于工作状态)。此时，若用户又需求使用前置摄像头，则用户可以再触发终端设备从后置摄像头切换到前置摄像头，即触发终端设备关闭后置摄像头，且开启前置摄像头并控制前置摄像头从终端设备内部伸出。
然而，上述过程中，当用户需求交替使用终端设备的前置摄像头和后置摄像头时，用户需要多次触发终端设备在前置摄像头和后置摄像头之间来回切换，如此导致终端设备的前置摄像头多次伸出和缩回，从而增加了摄像头的机械损耗，缩短了摄像头的使用寿命。
发明内容
本公开实施例提供一种摄像头切换方法及终端设备，以解决由于前置摄像头多次伸出和缩回，而增加前置摄像头的机械损耗，缩短前置摄像头的使用寿命的问题。

第二方面，本公开实施例提供了一种终端设备，该终端设备包括第一摄像头、第二摄像头、接收模块和处理模块，第一摄像头为伸缩摄像头。接收模块，用于在第一摄像头开启且处于伸出状态的情况下，接收用户的第一输入；处理模块，用于响应于接收模块接收的第一输入，关闭第一摄像头，并开启第二摄像头；其中，处理模块响应第一输入之后，第一摄像头保持伸出状态。
第三方面，本公开实施例提供了一种终端设备，包括处理器、存储器及存储在存 储器上并可在处理器上运行的计算机程序，计算机程序被处理器执行时实现上述第一方面的摄像头切换方法的步骤。
第四方面，本公开实施例提供了一种计算机可读存储介质，该计算机可读存储介质上存储计算机程序，该计算机程序被处理器执行时实现上述第一方面的摄像头切换方法的步骤。
在本公开实施例中，终端设备可以包括第一摄像头和第二摄像头，第一摄像头为伸缩摄像头。终端设备可以在第一摄像头开启且处于伸出状态的情况下，接收用户的第一输入；且响应于第一输入，关闭第一摄像头，并开启第二摄像头；其中，响应第一输入之后，第一摄像头保持伸出状态。通过该方案，由于在第一摄像头开启并处于伸出状态的情况下，用户可以通过第一输入触发终端设备从第一摄像头切换到第二摄像头(即关闭第一摄像头，开启第二摄像头)，并且可以在切换后使得第一摄像头仍然保持伸出状态，因此当用户需要再切换回第一摄像头时，终端设备可以直接关闭第二摄像头，并开启第一摄像头，即在摄像头切换过程中，终端设备无需再控制第一摄像头伸缩。如此，在第一摄像头和第二摄像头交替切换的过程中，终端设备无需再控制第一摄像头多次伸缩，从而降低了第一摄像头的机械损耗，提高了第一摄像头的使用寿命。

本公开实施例中，在用户触发终端设备在第一摄像头和第二摄像头切换的过程中，用户可以通过特定输入(例如下述的第一输入)触发终端设备只控制第一摄像头和第二摄像头之间的切换(即关闭一个，开启另一个)，无需再控制第一摄像头伸缩；即在控制第一摄像头和第二摄像头切换的过程中，可以使得第一摄像头一直保持伸出状态。具体的，在第一摄像头开启且处于伸出状态的情况下，用户可以通过第一输入触发终端设备关闭第一摄像头，并开启第二摄像头，以及保持第一摄像头处于伸出状态(即无需控制第一摄像头缩回到该终端设备内部)。从而，在用户又需求使用第一摄像头时，用户只需通过另一个输入触发终端设备关闭第二摄像头，并开启第一摄像头， 即可实现第一摄像头和第二摄像头之间的切换。如此，在第一摄像头和第二摄像头交替切换的过程中，终端设备无需再控制第一摄像头多次伸缩，从而降低了第一摄像头的机械损耗，提高了第一摄像头的使用寿命。
下面具体结合各个附图对本公开实施例提供的摄像头切换方法进行示例性地描述。
如图2所示，本公开实施例提供一种摄像头切换方法，该方法可以包括下述的S201和S202。
S201、在第一摄像头开启且处于伸出状态的情况下，终端设备接收用户的第一输入。
需要说明的是，本公开实施例中，上述第一摄像头可以为终端设备中的前置摄像头，且第一摄像头可以为伸缩摄像头。即第一摄像头可以在终端设备中伸缩。具体的，第一摄像头可以处于伸出状态，也可以处于缩回状态。

示例性地，当上述驱动机构为升降机构时，上述第一摄像头可以为垂直升降式伸缩摄像头；当上述驱动机构为旋转机构时，上述第一摄像头可以为半旋转式伸缩摄像头。
具体的，本公开实施例中，当第一摄像头为垂直升降式伸缩摄像头时，终端设备可以通过升降机构控制第一摄像头从终端设备内部伸出或缩回到终端设备内部。当第一摄像头为半旋转式伸缩摄像头时，终端设备可以通过旋转机构控制第一摄像头从终端设备内部伸出(或称为从终端设备内部旋出)或缩回到终端设备内部(或称为旋入到终端设备内部)。
可选地，本公开实施例中，当上述第一摄像头开启且处于伸出状态时，终端设备可以在终端设备前台运行相机应用。或者，当第二摄像头开启时，终端设备可以在终端设备前台运行相机应用。可以理解，实际实现中，在终端设备在终端设备的前台运行相机应用的情况下，终端设备中至少有一个摄像头开启。
可选地，本公开实施例中，用户可以通过对相机应用的图标输入，触发终端设备在终端设备的前台运行相机应用(即用户触发终端设备直接打开相机应用)，此时终 端设备可以开启第一摄像头或第二摄像头。用户也可以通过在其它应用程序的界面上的输入，触发终端设备在终端设备的前台运行相机应用(即用户触发终端设备通过其他应用程序调用相机应用)，此时终端设备可以开启第一摄像头或第二摄像头。
本公开实施例中，终端设备在终端设备的前台运行相机应用时，终端设备的显示屏上可以显示相机应用的相机预览界面。其中，相机预览界面可以为第一摄像头的预览界面或第二摄像头的预览界面。具体可以根据当前开启的摄像头确定，本公开实施例不作限定。
对于相机预览界面的具体描述可以参见上述名词解释部分对相机预览界面的相关描述，此处不再赘述。
可选地，本公开实施例中，上述第一输入可以为用户在上述相机预览界面上的输入，也可以为用户对终端设备执行预设手势的输入。具体可以根据实际使用需求确定，本公开实施例不作限定。
一种实现方式中，当上述第一输入为用户在上述相机预览界面上的输入时，第一输入具体可以为用户对相机预览界面中的第一控件的输入，上述S201具体可以通过下述的S201a实现。
S201a、在第一摄像头开启且处于伸出状态的情况下，终端设备接收用户对第一控件的第一输入。
其中，上述第一控件为相机预览界面中的控件。对第一控件的第一输入可以用于触发终端设备关闭第一摄像头，并开启第二摄像头，以及使得第一摄像头保持伸出状态。
可选地，本公开实施例中，上述第一输入可以为点击输入、长按输入或者重按输入等任意可能形式的输入，具体可以根据实际使用需求确定，本公开实施例不作限定。
其中，上述点击输入可以为单击、双击或者连续点击预设次数的输入。上述长按输入可以为接触预设时间的输入。上述重按输入也称为压力触控输入，是指用户以大于或等于压力阈值的压力值按下的输入。
需要说明的是，上述预设次数、预设时间以及压力阈值均可以根据实际使用需求确定，本公开实施例不作限定。
可选地，本公开实施例中，上述相机预览界面中还可以包括第四控件。第四控件可以用于触发终端设备在不同摄像头之间切换。例如，在第一摄像头开启且处于伸出状态的情况下，用户可以通过对第四控件的输入，触发终端设备关闭第一摄像头，并开启第二摄像头，以及控制第一摄像头处于缩回状态。或者，在第二摄像头开启的情况下，用户可以通过对第四控件的输入，触发终端设备关闭第二摄像头，并开启第一摄像头，以及控制第一摄像头处于伸出状态。即用户可以通过对第四控件的输入，触发终端设备在不同摄像头之间切换。
另一种实现方式中，当上述第一输入为用户对终端设备执行预设手势的输入时，上述S201具体可以通过下述的S201b实现。
S201b、在第一摄像头开启且处于伸出状态的情况下，终端设备接收用户执行预设手势的第一输入。
本公开实施例中，上述第一输入可以为用户的手相对于终端设备或者终端设备的 屏幕的手势输入。
可选地，本公开实施例中，终端设备接收用户对终端设备执行与预设手势对应的第一输入之前，终端设备可以先检测用户的手势，在检测到用户执行预设手势时，终端设备可以确定接收到第一输入。
可选地，本公开实施例中，上述预设手势可以为任意可能实现本方案的手势。例如，上述预设手势可以为用户的手沿预设方向移动的手势，或者可以为用户的手沿预设轨迹移动的手势，以及可以是其它任意可能实现本方案的手势，具体可以根据实际使用需求确定，本公开实施例不作限定。
S202、终端设备响应于第一输入，关闭第一摄像头，并开启第二摄像头。
其中，终端设备响应第一输入之后，第一摄像头可以保持伸出状态。即终端设备响应第一输入之后，终端设备可以不控制第一摄像头缩回到终端设备内部。
可以理解，本公开实施例中，上述终端设备关闭第一摄像头，是指终端设备控制第一摄像头停止工作，即终端设备停止通过第一摄像头采集图像。上述终端设备开启第二摄像头，是指终端设备控制第二摄像头开始工作，即终端设备开始通过第二摄像头采集图像。
可选地，本公开实施例中，上述第一摄像头保持伸出状态，是指终端设备在从第一摄像头切换到第二摄像头时，只关闭第一摄像头，而无需控制第一摄像头缩回到终端设备内部(即无需控制第一摄像头处于缩回状态)。如此，当终端设备再从第二摄像头切换到第一摄像头时，终端设备可以无需控制第一摄像头从终端设备内部伸出，即在摄像头切换过程中，终端设备无需控制第一摄像头伸缩，从而可以降低第一摄像头的机械损耗，并提高第一摄像头的使用寿命。
下面再结合图3和图4对上述S201和S202所示的摄像头切换方法进行进一步示例性地说明。
示例性地，假设终端设备包括第一摄像头和第二摄像头，且第一摄像头为垂直升降式伸缩摄像头。又假设第一摄像头开启且处于伸出状态，且终端设备显示的相机预览界面为第一摄像头的预览界面，并且相机预览界面中包括第一控件和拍摄预览区，以及拍摄预览区中显示第一摄像头的拍摄预览图像(即第一摄像头采集的预览图像)。再假设第一输入为用户对第一控件的点击输入。那么，如图3中的(a)所示，第一摄像头31处于伸出状态，且终端设备的显示屏上显示相机预览界面(即第一摄像头的预览界面)，该相机预览界面中包括第一控件32和拍摄预览区33，该拍摄预览区33中显示第一摄像头31的拍摄预览图像(即第一摄像头31采集的预览图像)。此时，用户点击第一控件32，即终端设备接收到用户对第一控件的第一输入，那么终端设备响应于该第一输入，如图3中的(b)所示，终端设备可以关闭第一摄像头31，并开启第二摄像头，以及第一摄像头31保持伸出状态，且拍摄预览区33中显示的拍摄预览图像从第一摄像头采集的预览图像切换为第二摄像头采集的预览图像。
本公开实施例提供的摄像头切换方法中，由于在第一摄像头开启且处于伸出状态的情况下，用户可以通过第一输入触发终端设备从第一摄像头切换到第二摄像头(即关闭第一摄像头，开启第二摄像头)，并且可以在切换后使得第一摄像头仍然保持伸出状态，因此当用户需要再切换回第一摄像头时，终端设备可以直接关闭第二摄像头， 并开启第一摄像头，即在摄像头切换过程中，终端设备无需再控制第一摄像头伸缩。如此，在第一摄像头和第二摄像头交替切换的过程中，终端设备无需再控制第一摄像头多次伸缩，从而降低了第一摄像头的机械损耗，提高了第一摄像头的使用寿命。
可选地，本公开实施例中，终端设备执行上述S202之后，可以继续在相机预览界面中显示第一控件；也可以取消第一控件在相机预览界面中的显示。具体可以根据实际使用需求确定，本公开实施例不作限定。
可以理解，本公开实施例中，在终端设备执行上述S202之后，无论第一控件是否继续在相机预览界面中显示，终端设备均可以在相机预览界面中显示上述第四控件。
可选地，本公开实施例中，在终端设备执行上述S202之后，终端设备可以在相机预览界面中显示第二控件。这种情况下，如果用户不再需求使用第一摄像头，那么用户可以通过对第二控件执行一个输入(例如下述第二输入)，触发终端设备在第二摄像头开启的情况下，控制第一摄像头缩回到终端设备内部(即处于缩回状态)。
示例性地，结合上述图2，如图4所示，在上述S202之后，本公开实施例提供的摄像头切换方法还可以包括下述的S203和S204。并且，上述S201具体是通过上述S201a实现的。
S203、终端设备接收用户对第二控件的第二输入。
可选地，本公开实施例中，上述第二输入可以为点击输入、长按输入或者重按输入等任意可能形式的输入，具体可以根据实际使用需求确定，本公开实施例不作限定。对于点击输入、长按输入以及重按输入的描述具体可以参见上述S201a中对第一输入的相关描述，此处不再赘述。
可选地，上述第二控件与上述第一控件可以为相同的控件，也可以为不同的控件，具体可以根据实际使用需求确定，本公开实施例不作限定。
S204、终端设备响应于第二输入，控制第一摄像头处于缩回状态。
可以理解，本公开实施例中，终端设备控制第一摄像头处于缩回状态，可以理解为终端设备控制第一摄像头从伸出状态切换为缩回状态，也即终端设备控制第一摄像头缩回到终端设备内部之后，第一摄像头所处的状态。
本公开实施例中，终端设备可以通过上述驱动机构控制第一摄像头缩回到终端设备内部。具体的，对于驱动机构的描述具体可以参见上述实施例中对驱动机构的相关描述，此处不再赘述。
下面再结合图5对上述S203-S204所示的摄像头切换方法进行进一步示例性地说明。
假设第二摄像头开启，第一摄像头关闭，且第一摄像头保持伸出状态，以及相机预览界面中显示第二控件。又假设第二输入为用户对第二控件的长按输入。那么，如图5中的(a)所示，第一摄像头51处于从伸出状态，且终端设备的显示屏上显示相机预览界面，该相机预览界面中包括第二控件52和拍摄预览区53，且该拍摄预览区53中显示第二摄像头的拍摄预览图像(即第二摄像头采集的预览图像)。此时，用户长按第二控件52，即终端设备接收到用户对第二控件的第二输入，那么终端设备响应于该第二输入，如图5中的(b)所示，终端设备控制第一摄像头处于缩回状态(即第一摄像头缩回到终端设备内部的状态)，且该拍摄预览区53中继续显示第二摄像头的 拍摄预览图像(即第二摄像头采集的预览图像)。
本公开实施例中，由于用户可以在第二摄像头开启(即第二摄像头处于工作状态)，且用户不再需求使用第一摄像头时，可以通过对第二控件的第二输入，触发终端设备控制第一摄像头处于缩回状态，即控制第一摄像头缩回到终端设备内部。因此，增加了用户使用摄像头的灵活性，提高了人机交互性能。
可选地，本公开实施例中，在终端设备执行上述S202之后，终端设备可以取消第一控件在相机预览界面中的显示。
示例性地，结合上述图2，如图6所示，在上述S202之后，本公开实施例提供的摄像头切换方法还可以包括下述的S205。
S205、终端设备取消第一控件在相机预览界面中的显示。
其中，S205中的相机预览界面可以为第二摄像头的预览界面，即相机预览界面的拍摄预览区中显示第二摄像头的拍摄预览图像(也即显示第二摄像头采集的预览图像)。
需要说明的是，终端设备取消第一控件在相机预览界面中的显示之后，可以继续在相机预览界面中显示第四控件，且第一摄像头可以保持伸出状态。此时，若用户需求使用第一摄像头，那么用户可以通过对第四控件的输入，触发终端设备关闭第二摄像头，并开启第二摄像头。如此，即可从第二摄像头切换到第一摄像头，而无需控制第一摄像头从缩回状态切换至伸出状态(可以理解，这种情况下，无需再控制第一摄像头从终端设备内部伸出)，避免了第一摄像头的频繁伸缩。
示例性地，如图3中的(b)所示，终端设备关闭第一摄像头31，并开启第二摄像头，以及第一摄像头31保持伸出状态之后，终端设备可以在拍摄预览区33中显示第二摄像头的拍摄预览图像(即第二摄像头采集的预览图像)，并取消第一控件在相机预览界面中的显示。
本公开实施例中，由于用户可以通过对第四控件的输入，触发终端设备再次从第二摄像头切换为第一摄像头，且在切换过程中，终端设备只需关闭第二摄像头，且开启第一摄像头即可，无需再控制第一摄像头从缩回状态切换至伸出状态(可以理解，这种情况下，无需再控制第一摄像头从终端设备内部伸出)。如此，在第一摄像头和第二摄像头交替切换的过程中，终端设备无需再控制第一摄像头多次伸缩，从而降低了第一摄像头的机械损耗，提高了第一摄像头的使用寿命。
进一步的，本公开实施例中，在终端设备关闭第二摄像头，并开启第一摄像头之后，终端设备即可在相机预览界面中显示第一摄像头的拍摄预览图像(即第一摄像头采集的预览图像)。由于第一摄像头为伸缩摄像头，且伸缩摄像头从终端设备内部伸出需要一定时间，并且在伸缩摄像头完全从终端设备内部伸出之后(即第一摄像头处于伸出状态之后)，相机预览界面中才会显示该伸缩摄像头的拍摄预览图像(即该伸缩摄像头采集的预览图像)。因此，与传统伸缩摄像头的伸出过程相比，本公开实施例中，由于只需关闭第二摄像头，并开启第一摄像头，即可在相机预览界面中显示第一摄像头的拍摄预览图像(即第一摄像头采集的预览图像)。因此，缩短了从第二摄像头切换到第一摄像头的切换时间，从而加快了终端设备的响应速度，提高了用户体验。
可选地，本公开实施例中，当终端设备关闭第一摄像头，并开启第二摄像头，即 终端设备从第一摄像头切换到第二摄像头之后，终端设备中的相机应用在终端设备的前台运行。此时，终端设备可以检测相机应用的运行状态，并在检测到相机应用关闭或者相机应用切换到在终端设备的后台运行时，终端设备可以控制第一摄像头处于缩回状态。
示例性地，结合上述图2，如图7所示，在上述S202之后，本公开实施例提供的摄像头切换方法还可以包括下述的S206。
S206、终端设备在检测到相机应用关闭或切换到终端设备的后台运行的情况下，控制第一摄像头处于缩回状态。
对于后台运行的描述具体可以参见上述名词解释部分对后台运行的相关描述，此处不再赘述。
本公开实施例中，当终端设备中的相机应用关闭或者从在终端设备的前台运行切换到在终端设备的后台运行时，终端设备可以自动控制第一摄像头从伸出状态切换为缩回状态，可以理解，终端设备可以自动控制第一摄像头缩回到终端设备内部。
可以理解，本公开实施例中，当终端设备中的相机应用在终端设备的前台运行，且第一摄像头处于伸出状态时，终端设备中开启的摄像头可以为第一摄像头，也可以为第二摄头。即在第一摄像头开启或第二摄像头开启的情况下，终端设备中的相机应用均在终端设备的前台运行。
可选地，本公开实施例中，用户可以通过对终端设备中的home键或者返回键输入，触发相机应用从在终端设备的前台运行切换到在终端设备的后台运行。
可选地，本公开实施例中，用户可以通过对终端设备中的最近运行程序界面输入，触发终端设备关闭终端设备中的相机应用。实际实现中，在用户对终端设备中的最近运行程序界面输入之前，用户可以先通过一个输入触发终端设备显示最近运行程序界面。
可选地，本公开实施例中，当终端设备中的相机应用关闭或者从在终端设备的前台运行切换到在终端设备的后台运行时，终端设备还可以控制第二摄像头关闭。
本公开实施例中，由于终端设备在检测到相机应用关闭或者从在终端设备的前台运行切换到在终端设备的后台运行时，可以自动控制第一摄像头处于缩回状态，并可以自动控制第二摄像头关闭。因此，可以防止第一摄像头长时间暴露在终端设备外部，从而可以提高第一摄像头的使用寿命。
可选地，本公开实施例中，在上述S201中的在第一摄像头开启且处于伸出状态的情况下，在终端设备接收上述第一输入之前，本公开实施例提供的摄像头切换方法还可以包括下述的S207；并且，上述S201具体可以通过下述的S201c实现。
S207、在第一摄像头开启且处于伸出状态的情况下，终端设备显示第三控件。
S201c、终端设备接收用户的第一输入。
可选地，本公开实施例中，上述第三控件可以为上述相机预览界面中显示的控件。上述第三控件可以用于指示上述第一摄像头是否处于锁定状态。
其中，上述第一摄像头处于锁定状态可以理解为：锁定第一摄像头处于伸出状态。即在第一摄像头处于锁定状态时，无论终端设备是否切换摄像头，第一摄像头均处于伸出状态。
示例性地，上述第三控件可以为如图5中的(a)的521所示的锁形控件。该锁形控件可以具有锁住状态和打开状态两种显示状态。当终端设备以锁住状态显示锁形控件时，可以指示第一摄像头处于锁定状态；当终端设备以打开状态显示锁形控件时，可以指示第一摄像头处于非锁定状态。其中，在第一摄像头处于锁定状态时，无论终端设备是否切换摄像头，第一摄像头均处于伸出状态；在第一摄像头处于非锁定状态时，随着终端设备切换摄像头，第一摄像头进行伸缩。
需要说明的是，图5中是以锁形控件处于锁住状态为例进行示意的，其并不对本公开实施例造成任何限定，实际实现中，锁形控件可以在不同情况下具有不同的显示状态，例如上述锁住状态或打开状态。
本发明实施例中，第一摄像头保持伸出状态可以包括：在第三控件指示第一摄像头处于锁定状态的情况下，第一摄像头保持伸出状态。
本公开实施例中，由于第三控件可以用于指示第一摄像头是否处于锁定状态，因此用户可以通过触发终端设备更新第三控件的显示状态，以实现第一摄像头在锁定状态和非锁定状态之间切换，从而可以增加用户使用摄像头的灵活性，提高人机交互性能。
需要说明的是，本公开实施例中，上述各个方法附图所示的摄像头切换方法均是以结合本公开实施例中的一个附图为例示例性地说明的。具体实现时，上述各个方法附图所示的摄像头切换方法还可以结合上述实施例中示意的其它可以结合的任意附图实现，此处不再赘述。
