Description

提示摄像头状态的方法及电子设备
本申请要求于2021年7月28日提交国家知识产权局、申请号为202110859099.0、申请名称为“提示摄像头状态的方法及电子设备”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
本申请涉及终端技术领域，尤其涉及一种提示摄像头状态的方法及电子设备。
背景技术
随着终端技术的发展和普及，电子设备逐渐集成了越来越多的功能。手机等电子设备中通常设置有摄像头，该电子设备中的应用程序可以通过调用摄像头进行拍摄来获取图像。由于在实际应用中，这种拍摄操作可能会导致用户隐私泄露，因此需要及时对摄像头的状态进行提示。
现有技术中，电子设备可以在检测到摄像头处于打开状态时，在显示屏的右上角显示一个黄色的光点，因此，用户可以通过观察显示屏的右上角是否存在该光点，来判断摄像头是否处于打开状态。但这种提示方式不够明显，用户极有可能会忽略掉该光点，提示效果较差。
发明内容
有鉴于此，本申请提供一种提示摄像头状态的方法及电子设备，能够显著地提示摄像头的状态，提高提示效果。
为了实现上述目的，第一方面，本申请实施例提供一种提示摄像头状态的方法，包括：
检测第一摄像头的状态；
若检测到所述第一摄像头处于打开状态，则在显示屏的第一区域显示第一提示信号，其中，所述第一区域与第二摄像头所在的第二区域相邻，所述第一提示信号用于提示当前所述第一摄像头处于打开状态。
其中，第一区域与第二区域相邻，可以是指电子设备在至少一种使用形态时，第一区域和第二区域之间的距离小于或等于特定距离。在一些实施例中，如果第一区域与第二区域之间为显示屏的部分区域，则该部分区域不用于显示任何通知消息，也不包括任何用于与用户交互的对象(比如应用程序的图标)。如果第一区域与第二区域之间为电子设备的部分机身外壳，则该部分机身外壳上不包括任何外露的元器件，比如喇叭或麦克风等。当第一区域和第二区域越接近，且第一区域和第二区域包括的元器件、通知消息或图标等可能干扰用户感知的因素越少，在第一区域所显示的示信号与第二区域的摄像头的关联性也就越强，从而以使得用户能够更好地将提示信号与摄像头联系起来，提示效果也就越好。
在本申请实施例中，电子设备可以在检测到第一摄像头处于打开状态时，通过显 示屏中与第二区域相邻的第一区域显示第一提示信号。由于第二的区域为第二摄像头所在的区域，那么当在第一区域显示第一提示信号时，用户可以很容易地将第一提示信号与摄像头相关联，从而确定第一提示信号所提示的内容为第一摄像头当前处于打开状态。与在显示屏下显示弹窗的方式相比，提示过程不会打断用户的其他操作，用户体验良好。与在显示屏右上角显示黄色光点的方式相比，能够更准确地提示用户当前是摄像头被调用，而不是定位或者录音等其他功能被调用，提示方式更为显著，也降低了用户的学习成本。另外，当用户在感知到第一提示信号时，可能会希望关闭第一摄像头，因此电子设备可以基于第一区域或额外的触控感知区域，快速关闭打开的第一摄像头，提供更好的隐私保护效果。
可选地，所述第一提示信号包括第一光信号。
其中，第一光信号的任一色彩属性可以是固定的，也可以是随提示时长而变化的。当该光信号的任一色彩属性可以随提示时长变化时，能够起到更好的提示效果。在一些实施例中，第一光信号的色相和色调可以不变，明度按照从低到高再到低的方式循环变化。在一些实施例中，第一光信号的色调和明度可以不变，色相按照预设方式的循环变化。
可选地，所述第一提示信号包括第一应用程序的应用标识，所述第一应用程序为请求打开所述第一摄像头的应用程序。
其中，还可以在第一区域显示文字和图标，从而提示与摄像头状态相关的更多信息，比如通过应用标识指示打开摄像头的应用程序，进一步提高提示效果。
可选地，所述第一区域包围所述第二区域。
其中，如果第二区域与第一区域不在同一平面内，则第一区域包围第二区域可以包括，第一区域包围第二区域在第一区域所在平面上的投影。
若第一区域包围第二区域，则可以使得第一提示信号可以环绕第二摄像头，提高第一提示信号与摄像头的关联性。
可选地，第一区域与第二区域在同一平面内。
其中，第一区域与第二区域在同一平面内，也可以使得第一提示信号与摄像头的关联性更强，从而提高提示效果。
可选地，所述第一区域为圆形区域、矩形区域或扇形区域。
在一些实施例中，第一区域的形状可以与第二区域的形状为相似图形。
可选地，在所述在显示屏的第一区域显示第一提示信号之前，还包括：
基于预设的屏幕切割区域参数，确定所述第二区域；
确定所述显示屏的最小触控块尺寸；
基于所述第二区域和所述最小触控块尺寸，确定所述第一区域。
其中，最小触控块可以为显示屏中能够清楚无疑义地接收用户触控操作的最小区域，该最小触控块的尺寸或者确定方式，可以由电子设备接收相关技术人员提交得到。在一些实施例中，电子设备可以获取存储的显示屏的触控板(TP，touchpad)行数和TP列数，该显示屏横向像素数除以TP列数所得到的数值即可以为最小触控块的宽度，该显示屏纵向像素数除以TP行数所得到的数值即可以为最小触控块的高度。在另一些实施例中，电子设备可以获取存储的最小触控块尺寸。
电子设备可以通过屏幕切割区域参数以及最小触控块尺寸，自动匹配得到第一区域，提高了确定第一区域的效率。
在一些实施例中，上述最小触控块尺寸也可以被代替为预设尺寸。
可选地，还包括：
基于对所述第一区域的第一拖动操作，更新所述第一区域的位置；和或，
基于对所述第一区域的第一缩放操作，更新所述第一区域的尺寸。
由于在实际应用中，电子设备种类繁多，自动适配所得到的第一区域可能不能完美地与该电子设备的第二区域相匹配，因此电子设备可以基于用户的第一拖动操作或第一缩放操作，对自动匹配得到的第一区域的位置或尺寸进行更新，从而精确调整第一区域，提高了第一区域的准确性。
在一些实施例中，电子设备可以在显示屏显示第三边框，其中，第三边框的形状可以是预先设置的，第一边框的位置和尺寸都可以是随机的数值或者预设的数值。电子设备可以基于第三边框接收用户的第二拖动操作，基于第二拖动操作确定第一区域的位置；基于第三边框接收用户第二缩放操作，将第二缩放操作缩放后的尺寸确定为第一区域的尺寸。也即是，电子设备也可以仅根据用户操作来确定第一区域，便于在难以自动匹配得到第一区域的情况下(比如无法获取到屏幕切割区域参数)，也能够确定第一区域，提高确定第一区域的可靠性。
可选地，还包括：
若基于第三区域接收到第一触发操作，则关闭所述第一摄像头，所述第三区域为所述第一区域，或者，所述第三区域为与所述第一区域相邻的触控感知区域。
其中，第三区域为与第一区域相邻的触控感知区域，则电子设备可以通过与确定第一区域相似的方式确定第三区域。在一些实施例中，若第三区域与第一区域不为同一区域，则第一区域和第三区域可以在同一平面内。在一些实施例中，若第三区域与第一区域不为同一区域，则第三区域可以包围第一区域。在一些实施例中，第三区域的形状可以与第一区域的形状为相似图形。
可选地，还包括：
若基于第三区域接收到第一触发操作，并通过所述第一摄像头检测到感光度下降且下降的数值变化量大于或等于第一感光度阈值，则关闭所述第一摄像头，所述第三区域为所述第一区域，或者，所述第三区域为与所述第一区域相邻的触控感知区域。
可选地，还包括：
若基于第三区域接收到第一触发操作，并通过所述第一摄像头检测到感光度下降且下降后的数值小于第二感光度阈值，则关闭所述第一摄像头，所述第三区域为所述第一区域，或者，所述第三区域为与所述第一区域相邻的触控感知区域。
可选地，所述第一触发操作为由所述第三区域指向所述第二区域的方向，且滑动轨迹的至少部分处于所述第三区域的滑动操作。
在一些实施例中，电子设备可以在先基于第三区域接收到第一触发操作，再通过所述第一摄像头检测到感光度下降且下降的数值变化量大于或等于第一感光度阈值，或者，再通过所述第一摄像头检测到感光度下降且下降后的数值小于第二感光度阈值，则关闭摄像头，相应的，用户可以先按照由第三区域指向第二区域的方向开始滑动， 在滑动过程中逐渐接近并遮挡第一摄像头，进而使得第一摄像头的感光度降低，最终关闭第一摄像头。一方面符合用户在感知到第一摄像头开启之后并关闭的操作逻辑，另一方面也减少了误操作的可能。
可选地，还包括：
若基于第三区域接收到第二触发操作，则确定保持所述第一摄像头开启，所述第三区域为所述第一区域，或者，所述第三区域为与所述第一区域相邻的触控感知区域。
在一些实施例中，第二触发操作可以为由第二区域指向第三区域的方向，且滑动轨迹的至少部分处于第三区域的滑动操作；在另一些实施例中，第二触发操作可以为由第三区域指向第一边缘，且至少部分滑动轨迹处于第三区域的滑动操作，第一边缘为显示屏最接近第三区域的边缘。
可选地，所述第一提示信号的显示时长为第一预设时长。
可选地，还包括：
若在所述第一预设时长内，基于第三区域未接收到第一触发操作，则保持所述第一摄像头开启，所述第三区域为所述第一区域，或者，所述第三区域为与所述第一区域相邻的触控感知区域。
可选地，所述第三区域为与所述第一区域相邻的触控感知区域，且所述第三区域包围所述第一区域。
可选地，还包括：
若确定保持所述第一摄像头开启，则将所述第一区域显示的第一光信号更新为第二光信号。
其中，第二提示信号可以用于提示当前第一摄像头处于打开状态，且该打开状态是经过用户允许的。在一些实施例中，第二提示信号可以用于提供补光功能。
也即是，电子设备若确定关闭第一摄像头(比如在第一预设时长内，基于第三区域接收到第一触发操作)或者确定保持打开第一摄像头(比如在第一预设时长内基于第三区域未接收到第一触发操作，或者接收到第二触发操作)，即已经基于第一提示信号得到了用户的反馈，或者，虽然未得到用户反馈但已经充分起到了提示的作用，则可以停止显示第一提示信号(也可以理解为隐藏第一提示信号)。在一些实施例中，电子设备若确定保持第一摄像头开启，则可以停止在第一区域显示第一提示信号并在第一区域显示第二提示信号，即将在第一区域显示的第一提示信号更新为第二提示信号。
在一些实施例中，电子设备若基于第三区域接收到第五触发操作，则可以跳转至的打开第一摄像头的第一应用程序。
相似的，电子设备可以按照与提示第一摄像头状态的方式相似的方式，提示第二摄像头的状态，也可以按照控制第一摄像头的方式相似的方式，控制第二摄像头。
在一些实施例中，电子设备若检测到第二摄像头处于打开状态，则可以在第一区域显示第三提示信号。在一些实施例中，第三提示信号可以包括第三光信号和第二应用程序的应用标识中的至少一个，其中，第二应用程序为请求打开第二摄像头的应用程序。
需要说明的是，若第一摄像头与第二摄像头为同一摄像头，则第三提示信号即为第一提示信号，或者可以理解为第三提示信号与第一提示信号相同。当然，无论第一 摄像头与第二摄像头是否为同一摄像头，第三提示信号都可以与第一提示信号有所区别，也可以与第一提示信号相同，区别在于，若第一提示信号与第三提示信号相同，提示方式比较简洁，也能够降低对设备能力的要求；若第一提示信号和第三提示信号不同，则能够更加准确地提示用户当前是哪个摄像头处于打开状态。
在一些实施例中，电子设备可以在基于第三区域接收到第一触发操作，且基于第二摄像头检测到感光度下降的数值变化量大于或等于第三感光度阈值时，或者，在基于第三区域接收到第一触发操作，且基于第二摄像头检测到感光度下降且下降后的数值小于第四感光度阈值时，则关闭第二摄像头。
在一些实施例中，第三提示信号的显示时长可以为第二预设时长。
在一些实施例中，若第二摄像头当前处于开启状态，且该电子设备基于第三区域接收到第四触发操作，则可以保持第二摄像头开启。
在一些实施例中，若在第二预设时长内，基于第三区域未检测到第四触发操作，则可以确定保持第二摄像头开启。
也即是，电子设备若确定关闭第二摄像头或确定保持打开第二摄像头，则可以停止显示第三提示信号。在一些实施例中，该电子设备若确定保持第二摄像头开启，则可以停止在第一区域显示第三提示信号并在第一区域显示第四提示信号，即将在第一区域显示的第三提示信号更新为第四提示信号。
其中，第四提示信号可以用于提示当前第二摄像头处于打开状态，且该打开状态是经过用户允许的。在一些实施例中，第四光信号可以提供补光功能。
在一些实施例中，电子设备若基于第三区域接收到第五触发操作，则可以跳转至的打开第二摄像头的第二应用程序。
可选地，所述若检测到所述第一摄像头处于打开状态，则在显示屏的第一区域显示第一提示信号，包括：

检测第一摄像头的状态；
若检测到所述第一摄像头处于打开状态，则通过第一区域内的至少一个灯光组件显示第一提示信号，其中，所述第一区域包围第二摄像头所在的第二区域，所述第一提示信号用于提示当前所述第一摄像头处于打开状态。
第二方面具有与前述第一方面相似的效果，区别在于，在第一方面中，第一区域为显示屏中的部分区域，电子设备可以是通过绘制用户界面的方式显示提示信号，该提示信号是由第一区域内多个不同显示状态的像素叠加的结果。而第二方面中，第一 区域可以不是显示屏中的部分区域，而是包括至少一个灯光组件的区域，该灯光组件可以包括闪光灯或灯带模组，相应的，提示信号可以只包括光信号，电子设备不需要绘制用户界面。在后续过程中，电子设备可以仅依据摄像头的感光度变化来确定是否关闭摄像头，也不再依赖用户的手势交互。
可选地，所述灯光组件包括闪光灯或灯带模组。
可选地，若所述灯光组件包括所述灯带模组，则所述灯带模组为环绕所述第二区域的环形灯带模组。
可选地，所述第一光信号为第一功率的光信号，所述第一功率小于所述灯光组件的额定功率或者预设的第一功率阈值。
可选地，还包括：
若检测到所述第二摄像头处于打开状态，则通过第一区域内的至少一个灯光组件显示第三光信号。
可选地，所述第三光信号为第二功率的光信号，所述第二功率小于所述灯光组件的额定功率或者预设的第一功率阈值。
其中，第一功率或第二功率，小于灯光组件的额定功率或者预设的第一功率阈值，因此当该灯光组件发出第一光信号或第三光信号时，可以被认为是处于低功率输出模式，使得用户能够将第一光信号以及第三光信号，与其他情况下灯光模组发光的情况区别开，提高提示效果。

图1是本申请实施例提供的一例电子设备100的结构示意图。电子设备100可以包括处理器110、存储器120、通信模块130、显示屏140、摄像头150和传感器160等。
其中，处理器110可以包括一个或多个处理单元，存储器120用于存储程序代码和数据。在本申请实施例中，处理器110可执行存储器120存储的计算机执行指令，用于对电子设备100的动作进行控制管理。
通信模块130可以用于电子设备100的各个内部模块之间的通信、或者电子设备100和其他外部电子设备之间的通信等。示例性的，如果电子设备100通过有线连接的方式和其他电子设备通信，通信模块130可以包括接口等，例如USB接口，USB接口可以是符合USB标准规范的接口，具体可以是Mini USB接口，Micro USB接口，USB Type C接口等。USB接口可以用于连接充电器为电子设备100充电，也可以用于 电子设备100与外围设备之间传输数据。也可以用于连接耳机，通过耳机播放音频。该接口还可以用于连接其他电子设备，例如AR设备等。
或者，通信模块130可以包括音频器件、射频电路、蓝牙芯片、无线保真(wireless fidelity，Wi-Fi)芯片、近距离无线通讯技术(near-field communication，NFC)模块等，可以通过多种不同的方式实现电子设备100与其他电子设备之间的交互。
显示屏140用于显示图像，视频等。在一些实施例中，电子设备100可以包括1个或N个显示屏140，N为大于1的正整数。
摄像头150用于捕获静态图像或视频。在一些实施例中，电子设备100可以包括1个或N个摄像头150，N为大于1的正整数。例如，当电子设备100为手机时，可以包括一个设置在显示屏140一侧的前置摄像头，以及多个设置在与显示屏140相背的一侧的多个后置摄像头。
其中，前置摄像头可以为当用户使用电子设备100时，与用户相对的一面所设置的摄像头。以电子设备100为手机为例，当用户使用手机时，设置有显示屏140的一面与用户相对，设置在该面内的摄像头即为前置摄像头，设置在与该面相背的一面的摄像头即为后置摄像头。
传感器160可以包括压力传感器、触摸传感器和光传感器。
压力传感器用于感受压力信号，可以将压力信号转换成电信号。在一些实施例中，压力传感器可以设置于显示屏140。当有触摸操作作用于显示屏140，电子设备100根据压力传感器检测触摸操作强度。电子设备100也可以根据压力传感器的检测信号计算触摸的位置。在一些实施例中，作用于相同触摸位置，但不同触摸操作强度的触摸操作，可以对应不同的操作指令。例如：当有触摸操作强度小于第一压力阈值的触摸操作作用于短消息应用图标时，执行查看短消息的指令。当有触摸操作强度大于或等于第一压力阈值的触摸操作作用于短消息应用图标时，执行新建短消息的指令。
触摸传感器，也称“触控面板”。触摸传感器可以设置于显示屏140，由触摸传感器与显示屏140组成触摸屏，也称“触控屏”。触摸传感器用于检测作用于其上或附近的触摸操作。触摸传感器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140提供与触摸操作相关的视觉输出。在另一些实施例中，触摸传感器也可以设置于电子设备100的表面，与显示屏140所处的位置不同。
光传感器，可以用于感知环境光亮度，进而可以用于自适应调节屏幕亮度、在拍照时自动调节白平衡、检测是否有物体靠近等等。
可选地，电子设备100还可以包括外设设备(图中未示出)，例如鼠标、键盘、扬声器、麦克风等。
应理解，除了图1中列举的各种部件或者模块之外，本申请实施例对电子设备100的结构不做具体限定。在本申请另一些实施例中，电子设备100还可以包括比图示更多或更少的部件，或者组合某些部件，或者拆分某些部件，或者不同的部件布置。图示的部件可以以硬件，软件或软件和硬件的组合实现。
图2是本申请实施例的电子设备100的软件结构框图。
分层架构将软件分成若干个层，每一层都有清晰的角色和分工。层与层之间通过软件接口通信。在一些实施例中，电子设备100可以包括接入层、控制层和基础中间 层。
接入层可以用于向用户呈现各种各样的界面，并基于所呈现的界面与用户进行交互，包括设置界面中的控制开关，本申请实施例中第一区域和第三区域的位置选择，以及在第一区域和第三区域中的触控交互。
控制层可以用于对本申请实施例中的提示信号的显示或隐藏，以及与第一区域和第三区域的交互逻辑进行控制。
控制层又可分为前台和后台。
前台包括坐标控制模块、事件注册模块和摄像头控制模块。坐标控制模块可以用于根据电子设备中存储的屏幕切割区域(notch)参数以及TP参数，确定第一区域或第三区域的位置(如坐标)和尺寸。事件注册模块可以用于在应用程序框架(framework，图中未示出)注册与本申请实施例相关的各种事件，比如摄像头打开事件、触控滑动事件和摄像头感光变化事件等等。摄像头控制模块可以用于对摄像头的状态进行控制，包括开启或关闭等。
其中，屏幕切割区域可以是摄像头所在的区域，屏幕切割区域参数可以用于该指示屏幕切割区域的位置以及尺寸等。TP参数可以包括行数和列数，显示屏横向像素数除以列数即为显示屏的最小触控块的宽度，显示屏纵向像素数处于行数即为该最小触控块的高度。
后台包括位置匹配模块、事件监听模块、摄像头管理模块和通知管理模块。位置匹配模块可以根据前述坐标控制模块的计算结果，在显示屏中匹配确定第一区域或第三区域。事件监听模块可以用于监听前述事件注册模块所注册的各种事件，如摄像头打开事件和触控滑动事件等等。摄像头管理模块可以用于管理摄像头，如打开、关闭和前后台跳转等。通知管理模块可以用于进程或组件之间的消息通知，比如传递摄像头被打开的消息等等，也可以用于向用户通知某些信息。
基础中间层可以用于为前述接入层和控制层提供基础的硬件和软件支持。在一些实施例中，基础中间层可以包括华为移动服务(huawei mobile services，HMS)、窗口管理服务(window manager service，WMS)、活动组件管理服务(activity manager service，AMS)、应用程序包管理服务(package manage service，PMS)、结构化查询语言软件库(structured query language ite，SQLite)、广播(broadcast)服务和推送套件(push kit)中的一个或多个。
为了便于理解本申请施例中的技术方案，下面首先对本申请实施例的应用场景予以介绍。
电子设备中通常都设置有摄像头，用户可以通过相机等应用程序调用摄像头，从而拍摄图像，达到记录信息的目的。但目前电子设备中安装的应用程序的种类和数量越来越多，很多第三方的应用程序都可能会打开摄像头，并在用户不知情的情况下拍摄图像，这可能会侵犯用户隐私，因此需要对摄像头的状态进行提示，以便于用户感知该摄像头的状态。
在一些实施例中，电子设备对前置摄像头的提示方式可以如图3所示。请参照图3，电子设备的操作系统可以在相机框架注册针对前置摄像头的监听事件。当某个应用程序调用前置摄像头时，相机框架会监听到该调用事件并发出事件通知。操作系统捕 获到该通知时，在屏幕下方显示弹窗如图4所示，该弹窗包括“某应用请求打开前置摄像头”、禁止按钮和允许按钮，禁止按钮附近还显示有倒计时。如果电子设备基于禁止按钮接收到用户的点击操作，或者在该倒计时结束之前未接收到任何操作，则保持前置摄像头关闭。如果电子设备基于允许按钮接收到用户的点击操作，则打开前置摄像头。但如图4所示的这种提示方式为侵入式的提示，在该弹窗显示的过程中，用户只能在选择允许或禁止之后，才能够继续进行其他操作。
在一些实施例中，电子设备对前置摄像头的提示方式可以如图5所示。请参照图5，应用程序向相机框架请求打开前置摄像头，相机框架通知状态栏前置摄像头的调用状态为开，因此状态栏在显示屏显示黄色(图中示出为黑色)的光点如图6所示。相应的，相机框架在相机关闭时，可以通知状态栏前置摄像头的调用状态为关，因此状态栏将黄色的光点隐藏。对于用户来说，可以通过观察显示屏的右上角是否存在该光点，来判断摄像头是否处于打开状态。但这种提示方式不够明显，用户极有可能会忽略掉该光点，提示效果较差。另外，电子设备还通过显示屏的右上角的同一位置显示相同大小的另一颜色的光点，来表示另一种较为敏感的功能(如定位或录音)处于打开状态，这也会导致用户需要耗费时间和精力去记忆不同颜色的光点所表示的含义，学习成本较高。
为至少解决上述至少部分技术问题，本申请实施例提供了另一种提示摄像头状态的方法。
在本申请实施例中，电子设备可以在检测到第一摄像头处于打开状态时，通过显示屏中与第二区域相邻的第一区域显示第一提示信号。由于第二区域为第二摄像头所在的区域，那么当在第一区域显示第一提示信号时，用户可以很容易地将第一提示信号与摄像头相关联，从而确定第一提示信号所提示的内容为第一摄像头当前处于打开状态。与在显示屏下显示弹窗的方式相比，提示过程不会打断用户的其他操作，用户体验良好。与在显示屏右上角显示黄色光点的方式相比，能够更准确地提示用户当前是摄像头被调用，而不是定位或者录音等其他功能被调用，提示方式更为显著，也降低了用户的学习成本。
在一些实施例中，当用户在感知到第一提示信号时，可能会希望关闭第一摄像头，因此电子设备可以基于第一区域或额外的触控感知区域，快速关闭打开的第一摄像头，提供更好的隐私保护效果。
需要说明的是，本申请实施例可以被实现为一个应用程序(如摄像头提示程序)或者某个应用程序中的一个组件(如提示组件)，下述电子设备所执行的与本申请实施例相关的操作，实际上可以由电子设备通过该提示程序或该提示组件来执行。
下面以具体地实施例对本申请的技术方案进行详细说明。下面这几个具体的实施例可以相互结合，对于相同或相似的概念或过程可能在某些实施例不再赘述。
请参照图7，为本申请实施例所提供的一种提示摄像头状态的方法的流程图。需要说明的是，该方法并不以图7以及以下所述的具体顺序为限制，应当理解，在其它实施例中，该方法其中部分步骤的顺序可以根据实际需要相互交换，或者其中的部分步骤也可以省略或删除。该方法包括如下步骤：
S701，电子设备打开摄像头提示功能。
本申请实施例提供的提示摄像头状态的方法，其目的是在摄像头打开时及时提示用户，以减少第三方应用程序程序恶意拍摄等隐私泄露的情况的发生，但在实际应用中，可能并不是所有的用户都希望被提示，而即便是同一用户在某些场景下也不希望被提示，因此电子设备可以向用户提供相应的配置接入口，以便于用户灵活地对是否提示摄像头状态以及提示方式的相关细节进行配置。
在一些实施例中，电子设备可以在接收用户提交的第一设置操作时，确定打开摄像头提示功能，那么便可以通过后续步骤来提示摄像头的状态。相应的，电子设备也可以在接收到第二设置操作时，确定关闭摄像头提示功能，那么无论摄像头的状态如何，都不再对用户进行提示，或者，至少不会再按照本申请实施例所提供的方式进行提示。
其中，第一设置操作和第二设置操作的操作类型可以由电子设备事先确定，本申请实施例对第一设置操作和第二设置操作的操作类型不做具体限定。
在一些实施例中，电子设备可以向用户提供系统配置页面如图8所示，该系统配置页面包括“摄像头调用提示”选项以及与该选项对应的开关。当电子设备基于该开关接收到用户的点击操作(即第一设置操作)时，可以打开摄像头提示功能，并将该开关切换至开的状态。当电子设备再次基于该开关接收到用户的点击操作(第二设置操作)时，关闭摄像头提示功能，并将该开关切换至关的状态。
需要说明的是，在实际应用中，电子设备也可以通过其他方式来确定开启或关闭摄像头提示功能，而并不仅限于如图8所示的方式，本申请实施例对电子设备确定开启或关闭摄像头提示功能的方式不做具体限定。
还需要说明的是，在一些实施例中，电子设备也可以不基于用户的配置来确定是否打开摄像头提示功能，比如电子设备可以基于相关技术人员预先设置的判断策略来判断是否打开摄像头提示功能。或者，在另一些实施例中，在任何时机，电子设备都可以按照本申请实施例所提供方式来提示用户摄像头的状态，而不需要再开启或关闭摄像头提示功能，也就不需要执行S701，即S701为可选的步骤。
S702，电子设备在显示屏确定第一区域。
电子设备可以设置有显示屏，当用户使用该电子设备时，该显示屏可以总是或者大部时间是面向用户的。该电子设备还可能会包括一个以上的摄像头，其中可以包括设置在电子设备的显示屏所在的平面(比如该显示屏一侧的面板或者该显示屏内的某个位置)的第二摄像头，还可以包括设置在电子设备任一位置(比如与该显示屏向背的一面)的第一摄像头。那么，当某一摄像头被调用而处于打开状态时，即可以在显示屏靠近第二摄像头的第一区域来发出提示信号，一方面便于用户感知到该提示信号，另一方面也便于用户将该提示信号与摄像头联系在一起，即更容易确定该提示信号是用于提示当前有摄像头出打开状态的。因此，为了便于后续在第一区域对用户进行提示，电子设备可以在显示屏确定第一区域。
其中，电子设备可以基于第二摄像头的位置，自动匹配确定第一区域；或者，也可以接收用户的相关操作来确定第一区域，即由用户手工确定第一区域；或者，电子设备可以先自动匹配确定第一区域，再基于用户的相关操作对第一区域进行精确调整，进而最终确定第一区域。
在一些实施例中，电子设备在显示屏确定第一区域的方式，可以如下图9所示。
在一些实施例中，第一区域和第二区域可以在同一平面内，从而使得在第一区域所所显示的提示信号与摄像头的关联性更强，提高提示效果。
在一些实施例中，第一区域可以与第二摄像头所在的第二区域相邻。
其中，第一区域与第二区域相邻，可以是指电子设备在至少一种使用形态时，第一区域和第二区域之间的距离小于或等于特定距离。需要说明的是，该特定距离的大小以及计算单位可以相关技术人员确定，以计算单位为像素为例，该特定距离可以是100至200之间的任意数值个像素，本申请实施例对该特定距离的大小不做具体限定。
以前述图8所示的电子设备为例，该电子设备只有一种使用形态，第二摄像头设置在显示屏内部，那么显示屏的区域都与第二摄像头所在的第二区域处于同一平面。或者，另一种电子设备为可折叠设备，当该电子设备处于折叠状态时可以如图10所示，显示屏的一部分显示区域与摄像头所处的第二区域1001处于同一平面，那么便可以在该部分显示区域确定第一区域1002，以用于提示摄像头状态。
在一些实施例中，如果第一区域与第二区域之间为显示屏的部分区域，则该部分区域不用于显示任何通知消息，也不包括任何用于与用户交互的对象(比如应用程序的图标)。如果第一区域与第二区域之间为电子设备的部分机身外壳，则该部分机身外壳上不包括任何外露的元器件，比如喇叭或麦克风等。当第一区域和第二区域越接近，且第一区域和第二区域包括的元器件、通知消息或图标等可能干扰用户感知的因素越少，在第一区域所显示的示信号与第二区域的摄像头的关联性也就越强，从而以使得用户能够更好地将提示信号与摄像头联系起来，提示效果也就越好。
在一些实施例中，第一区域可以包围第二区域，从而使得提示信号可以环绕第二摄像头，提高提示信号与摄像头的关联性。
其中，如果第二区域与第一区域不在同一平面内，则第一区域包围第二区域可以包括，第一区域包围第二区域在第一区域所在平面上的投影。
在一些实施例中，第一区域的形状可以与第二区域的形状为相似图形。
在一些实施例中，如图11所示，第二摄像头所在的区域为第二区域1001，第一区域1002与第二区域1001相邻。第一区域1002可以为圆形区域，如图11中的a和图11中的b；或者，第一区域1002可以为矩形区域，如图11中的c和图11中的d所示；或者，第一区域1002可以为扇形区域，如图11中的e所示。其中，与图11中的a相比，图11中的b中第一区域1002与第二区域1001之间没有公共边界，即第一区域1002与第二区域1001之间可以存在空隙，因此图11中的b中的第一区域1002又可称之为环形区域；相似的，与图11中的c相比，图11中的d中第一区域1002与第二区域1001之间也没有公共边界；与图11中的a、b、c和d相比，图11中的e中第一区域1001设置在第二区域1001的一侧而非包围第二区域1001。
当然，在实际应用中，为了美观和提高提示效果等目的，第一区域也可以是其他形状的区域。
需要说明的是，第一区域可以是包括棱角，也可以包括对该棱角进行倒角处理后的圆角。例如，第一区域可以是具有四个直角的矩形区域，也可以是具有四个圆角的矩形，其中，四个圆角是通过分别对四个直角进行倒角处理得到的。
需要说明的是，由于第一区域是基于第二摄像头所在的第二区域来确定的，对于同一电子设备，由于其第二摄像头的位置以及排布是固定的，即第二区域(形状、尺寸和位置)是固定的，那么第一区域可以是固定的；而对于不同的电子设备，由于其第二摄像头的位置不同，第二区域也不同，那么相应的第一区域可以不同，从而呈现出不同电子设备可以包括形态各异的第一区域。
在一些实施例中，为了对摄像头进行控制，比如关闭摄像头，电子设备还可以设置用于用户触控操作的第三区域。在一些实施例中，第三区域可以与第一区域是同一区域。在另一些实施例中，第一显示区域可以只用于显示提示信号，电子设备额外确定作为触控感知区的第三区域，第三区域可以与第一区域相邻。
需要说明的是，电子设备确定第三区域的方式可以与确定第一区域的方式相同或相似。
在一些实施例中，若第三区域与第一区域不为同一区域，则第一区域和第三区域可以在同一平面内。
在一些实施例中，若第三区域与第一区域不为同一区域，则第三区域可以包围第一区域。
在一些实施例中，第三区域的形状可以与第一区域的形状为相似图形。
需要说明的是，电子设备可以按照与确定第一区域相似的方式，确定第三区域，且所确定的第三区域的位置和尺寸，也可以因不同的电子设备而异，此处不再一一赘述。
在一些实施例中，第一摄像头和第二摄像头可以为设置在电子设备的显示屏所在的平面的同一摄像头，比如同一前置摄像头。在另一些实施例中，第一摄像头设置在与该显示屏向背的一面，即后置摄像头，第二摄像头为前置摄像头。
S703，电子设备检测摄像头的状态。
为了在摄像头处于打开状态时及时对用户进行提示，电子设备可以检测摄像头当前是处于开启状态还是关闭状态。
在一些实施例中，电子设备检测摄像头的状态的方式，可以如下图12所示。但需要说明的是，在实际应用中，电子设备检测摄像头的状态的方式，并不限于如图12所示的方式，本申请实施例对电子设备检测摄像头的状态的方式不做具体限定。
S704，电子设备若检测到摄像头处于打开状态，则在第一区域显示提示信号。
当电子设备确定了与摄像头关联性较强的第一区域，且检测到有摄像头处于打开状态，则可以及时在第一区域提示用户，使得用户能够更及时准确地感知摄像头被打开这一事件，也便于后续对摄像头进行相关的控制操作。
在一些实施例中，提示信号可以包括光信号、文字和图标中的至少一种。
其中，光信号可以具有色相、色调和明度等三种色彩属性。提示信号所包括的光信号的任一色彩属性可以是固定的，也可以是随提示时长而变化的。当该光信号的任一色彩属性可以随提示时长变化时，能够起到更好的提示效果。
在一些实施例中，该光信号的色相和色调可以不变，明度按照从低到高再到低的方式循环变化。在一些实施例中，该光信号的色调和明度可以不变，色相按照预设方式的循环变化。
在一些实施例中，文字和图标可以包括请求打开摄像头的应用标识，从而提示与摄像头状态相关的更多信息，比如指示打开摄像头的应用程序，进一步提高提示效果。
需要说明的是，在实际应用中，提示信号并不限于上述的光信号、文字和图标。电子设备也可以通过更多或更少类型的提示信号，来提示用户摄像头处于打开状态，比如，电子设备可以将当前显示屏待显示的画面在第一区域内的第二图像进行反相处理，得到第一图像，然后将第一图像作为提示信号在第一区域进行显示，本申请实施例对该提示信号的类型不做具体限定。
在一些实施例中，电子设备可以基于用户提交的第三设置操作，确定提示信号的类型。
例如，电子设备若基于前述图8所示的系统设置界面的开关接收到用户的点击操作，则可以显示提醒信号配置选项如图13所示。该提醒信号配置选项包括“显示光信号”、“显示应用名称”和“显示应用图标”等三个选项，每个选项对应设置有开关。对于任一选项，电子设备若基于任一选项对应的开关接收到用户的点击操作，则可以确定提示信号的类型包括该选项所指示的类型。
在一些实施例中，电子设备若检测到第一摄像头处于打开状态，则可以在第一区域显示第一提示信号。在一些实施例中，第一提示信号可以包括第一光信号和第一应用程序的应用标识中的至少一个，其中，第一应用程序为请求打开第一摄像头的应用程序。
相似的，电子设备若检测到第二摄像头处于打开状态，则可以在第一区域显示第三提示信号。在一些实施例中，第三提示信号可以包括第三光信号和第二应用程序的应用标识中的至少一个，其中，第二应用程序为请求打开第二摄像头的应用程序。
需要说明的是，若第一摄像头与第二摄像头为同一摄像头，则第三提示信号即为第一提示信号，或者可以理解为第三提示信号与第一提示信号相同。当然，无论第一摄像头与第二摄像头是否为同一摄像头，第三提示信号都可以与第一提示信号有所区别，也可以与第一提示信号相同，区别在于，若第一提示信号与第三提示信号相同，提示方式比较简洁，也能够降低对设备能力的要求；若第一提示信号和第三提示信号不同，则能够更加准确地提示用户当前是哪个摄像头处于打开状态。
S705，电子设备检测预设控制事件。
由于摄像头在打开时可能并未得到用户允许，或者，该摄像头可能是由用户误操作打开的，总之用户可能当前希望快速关闭该摄像头，因此，电子设备可以检测预设控制事件，该预设控制事件用于触发关闭摄像头。
在一些实施例中，预设控制事件可以包括与第一摄像头对应的第一预设控制事件和与第二摄像头对应的第二预设控制事件。其中，第一预设控制事件用于触发关闭第一摄像头，第二预设控制事件用于触发关闭第二摄像头。
在一些实施例中，第一预设控制事件可以包括第一触控事件和第一感光度下降事件。
第一触控事件可以为基于第三区域接收到第一触发操作的事件。
由前述可知，第一区域与摄像头的关联性较强，因而能够直观地显示用于提示摄像头打开的提示号，而第三区域为第一区域或者与第一区域相邻的触控感知区域，与 摄像头的关联性也很强，因此基于第一触控事件来控制摄像头，能够符合大多数用户的思维习惯，提高操作的便利性。
需要说明的是，第一触发操作的操作类型可以由电子设备事先确定。在一些实施例中，第一触发操作可以为沿第一方向滑动且至少部分滑动轨迹处于第三区域的滑动操作。
还需要说明的是，第一方向可以由电子设备事先确定。在一些实施例中，第一方向可以为由第三区域指向第二区域的方向。
第一感光度下降事件可以为基于第一摄像头检测到感光度下降的数值变化量大于或等于第一感光度阈值的事件，或者，第一感光度事件可以为基于第一摄像头检测到感光度下降且下降后的数值小于第二感光度阈值的事件。
需要说明的是，第一感光度阈值或第二感光度阈值可以由电子设备事先确定。
在一些实施例中，第二预设控制事件可以包括第一触控事件和第二感光度下降事件。
第二感光度下降事件可以为基于第二摄像头检测到感光度下降的数值变化量大于或等于第三感光度阈值的事件，或者，第二感光度事件可以为基于第二摄像头检测到感光度下降且下降后的数值小于第四感光度阈值的事件。
需要说明的是，第三感光度阈值或第四感光度阈值可以由电子设备事先确定。在一些实施例中，第三感光度阈值可以与第一感光度阈值相同，第四感光度阈值可以与第二感光度阈值相同。
还需要说明的是，若第一摄像头与第二摄像头为同一摄像头，则第二预设控制事件即为第一预设控制事件。
还需要说明的是，第一预设控制事件(或第二预设控制事件)的类型和数量可以是电子设备事先设置的。
在一些实施例中，电子设备可以在执行S705之前，注册预设控制事件。在一些实施例中，电子设备可以在确定第一摄像头处于打开状态之后，注册第一预设控制事件；在确定第二摄像头处于打开状态之后，注册第二预设控制事件。
其中，以注册第一预设控制事件为例，电子设备可以通过提示组件，从与触控相关的组件中注册第一触控事件，从与摄像头相关的组件(比如相机框架)中注册第一感光度下降事件。
S706，电子设备若检测到预设控制事件，则关闭处于打开状态的摄像头。
其中，电子设备可以通过相机驱动，控制摄像头关闭。在一些实施例中，电子设备若检测到第一预设控制事件，则可以关闭第一摄像头；若检测到第二预设控制事件，则可以关闭第二摄像头。
需要说明的是，由前述可知，电子设备可以事先设置第一预设控制事件(或第二预设控制事件)的类型或数量。因此，以第一预设控制事件为例，若事先设置的第一预设控制事件的数量多于一个，则电子设备可以在检测到其中部分第一预设控制事件(比如至少一个)时关闭处于打开状态的摄像头，也可以在检测到全部第一预设控制事件时关闭处于打开状态的摄像头。
在一些实施例中，电子设备可以按照预设的检测顺序来检测多个预设控制事件。 当检测到某个预设控制事件时，继续检测下一预设控制事件，直至检测完成并关闭对应的摄像头。如果并未检测到下一预设控制事件，则可以保持该摄像头处于打开状态。相应的，用户可以通过与预设的检测顺序相匹配的操作顺序，才可以关闭该摄像头，因而能够减少因误操作关闭摄像头的可能，提高控制摄像头的准确性。
在一些实施例中，电子设备关闭摄像头的方式，可以参照下述图14所示。
在一些实施例中，第一提示信号的显示时长可以为第一预设时长。电子设备若在第一预设时长内，未检测到指定的至少一个或者全部的第一预设控制事件，则可以确定保持第一摄像头开启。相似的，第三提示信号的显示时长可以为第二预设时长。电子设备若在第二预设时长内，未检测到指定的至少一个或者全部的第二预设控制事件，则可以确定保持第二摄像头开启。也即是，在电子设备发出第一提示信号之后的第一预设时长内，如果用户没有手动关闭第一摄像头，则该电子设备可以保持第一摄像头开启；或者，电子设备发出在第三提示信号之后的第二预设时长内，如果用户没有手动关闭第二摄像头，则该电子设备可以保持第二摄像头开启。
需要说明的是，第一预设时长或第二预设时长可以由电子设备事先确定。本申请实施例对确定第一预设时长和第二预设时长的方式以及第一预设时长和第二预设时长的大小，不做具体限定。
还需要说明的是，若第一摄像头与第二摄像头为同一摄像头，则第二预设时长即为第一预设时长。
在一些实施例中，若第一摄像头当前处于开启状态，且电子设备基于第三区域接收到第二触发操作，则可以保持第一摄像头开启。相似的，若第二摄像头当前处于开启状态，且该电子设备基于第三区域接收到第四触发操作，则可以保持第二摄像头开启。也即是，用户可以主动通过第二触发操作来保持第一摄像头开启，或者主动通过第四触发操作保持第二摄像头开启。
其中，第二触发操作或第四触发操作的操作类型可以由电子设备事先确定。以第二触发操作为例，在一些实施例中，第二触发操作可以为由第二区域指向第三区域的方向，且滑动轨迹的至少部分处于第三区域的滑动操作；在另一些实施例中，第二触发操作可以为由第三区域指向第一边缘，且至少部分滑动轨迹处于第三区域的滑动操作，第一边缘为显示屏最接近第三区域的边缘。
需要说明的是，若第一摄像头与第二摄像头为同一摄像头，则第四触发操作即为第二触发操作。
在一些实施例中，电子设备若在第一预设时长内，基于第三区域未检测到第二触发操作，则可以确定保持第一摄像头开启。相似的，若在第二预设时长内，基于第三区域未检测到第四触发操作，则可以确定保持第二摄像头开启。
在一些实施例中，电子设备若确定关闭第一摄像头(比如在第一预设时长内，基于第三区域接收到第一触发操作)或者确定保持打开第一摄像头(比如在第一预设时长内基于第三区域未接收到第一触发操作，或者接收到第二触发操作)，即已经基于第一提示信号得到了用户的反馈，或者，虽然未得到用户反馈但已经充分起到了提示的作用，则可以停止显示第一提示信号，或者也可以理解为隐藏第一提示信号；相似的，该电子设备若关闭第二摄像头或确定保持打开第二摄像头，则可以停止显示第三提示 信号。
在一些实施例中，电子设备若确定保持第一摄像头开启，则可以停止在第一区域显示第一提示信号并第一区域显示第二提示信号，即将在第一区域显示的第一提示信号更新为第二提示信号。相似的，该电子设备若确定保持第二摄像头开启，则可以停止在第一区域显示第三提示信号并在第一区域显示第四提示信号，即将在第一区域显示的第三提示信号更新为第四提示信号。
其中，第二提示信号可以用于提示当前第一摄像头处于打开状态，且该打开状态是经过用户允许的；第四提示信号可以用于提示当前第二摄像头处于打开状态，且该打开状态是经过用户允许的。
需要说明的是，第二提示信号可以包括第二光信号，还可以包括第一应用程序的应用标识；第四提示信号可以包括第四光信号，还可以包括第二应用程序的应用标识。
在一些实施例中，第二光信号或第四光信号还可以提供补光功能。例如，第二光信号或第四光信号可以为白色的光信号。
在一些实施例中，若第一摄像头与第二摄像头为同一摄像头，则第四光信号即为第二光信号。当然，无论第一摄像头与第二摄像头是否为同一摄像头，第四提示信号都可以与第二提示信号有所区别，也可以与第二提示信号相同。
以图15所示电子设备为例。其中，第一摄像头与第二摄像头为位为第二区域1001的同一摄像头，第一区域1002与第三区域为同一区域，该电子设备在第一区域1002发出第一光信号。
若电子设备基于图15，接收到如图16所示的从位置1至位置2的滑动操作，其中，位置1处于第一区域1002外，位置2处于第一区域1002中。因此，电子设备可以确定检测到第一触控事件。但实际上由于用户在滑动至位置2时并未停止，而是继续滑动至处于第二区域1001中的位置3，当用户滑动至位置3时，会遮挡住位于第二区域1001的第一摄像头，第一摄像头所检测到的感光度会降低，所以电子设备还会检测到第一感光度下降事件。当电子设备检测到第一触控事件和第一感光度下降事件时，即可以关闭第一摄像头，并停止在第一区域1002显示第一光信号，如图17所示。
需要说明的是，在图16中，用户是通过手指遮挡第一摄像头(即手势交互)，从而使得第一摄像头检测到的感光度下降，在另一些实施例中，用户也可以通过将电子设备设置有第一摄像头的一面靠近障碍物来使得第一摄像头检测到的感光度下降，比如用户可以翻转电子设备从而使得第一摄像头倒扣在桌面上。
若电子设备基于图15，接收到如图18所示的从位置4至位置5的滑动操作，其中，位置4处于第一区域1002中，位置5处于第一区域1002外，为显示屏最靠近第一区域1002的边缘。因此电子设备可以保持第二区域1001中的第一摄像头开启。当电子设备保持第一摄像头开启时，可以停止在第一区域1002显示第一光信号，如图17所示，也可以将第一区域1002显示的第一光信号更新为第二光信号，如图19所示，从而通过第二光信号进行补光，提高第一摄像头的拍摄效果。
在一些实施例中，电子设备若基于第三区域接收到第五触发操作，则可以跳转至第一应用程序或第二应用程序。
需要说明的是，第五触发操作的类型可以由电子设备事先确定。在一些实施例中， 第五触发操作可以包括按压操作或双击操作。当然，在实际应用中，第五触发操作还可以是其他类型的操作，本申请实施例对第五触发操作的操作类型不做具体限定。
在本申请实施例中，电子设备可以在检测到第一摄像头处于打开状态时，通过显示屏中与第二区域相邻的第一区域显示第一提示信号。由于第二的区域为第二摄像头所在的区域，那么当在第一区域显示第一提示信号时，用户可以很容易地将第一提示信号与摄像头相关联，从而确定第一提示信号所提示的内容为第一摄像头当前处于打开状态。与在显示屏下显示弹窗的方式相比，提示过程不会打断用户的其他操作，用户体验良好。与在显示屏右上角显示黄色光点的方式相比，能够更准确地提示用户当前是摄像头被调用，而不是定位或者录音等其他功能被调用，提示方式更为显著，也降低了用户的学习成本。另外，当用户在感知到第一提示信号时，可能会希望关闭第一摄像头，因此电子设备可以基于第一区域或额外的触控感知区域，快速关闭打开的第一摄像头，提供更好的隐私保护效果。
请参照图9，为本申请实施例所提供的一种确定第一区域的方法的流程图。需要说明的是，该方法并不以图9以及以下所述的具体顺序为限制，应当理解，在其它实施例中，该方法其中部分步骤的顺序可以根据实际需要相互交换，或者其中的部分步骤也可以省略或删除。该方法包括如下步骤：
S901，电子设备确定第二摄像头所在的第二区域。
在一些实施例中，第二摄像头设置在显示屏的边缘或内部，显示屏对应设置有用于安置第二摄像头的屏幕切割区域，该显示屏可以为“刘海屏”、“水滴屏”或“挖孔屏”等。电子设备中可以预先存储有屏幕切割区域参数，因此，电子设备可以获取该屏幕切割区域参数，基于该屏幕切割区域参数确定第二区域。
其中，屏幕切割区域参数可以用于指示屏幕切割区域。在一些实施例中，屏幕切割区域参数可以包括该屏幕切割区域的高度、宽度以及距离显示屏边缘的距离。在一些实施例中，屏幕切割区域参数可以包括该屏幕切割区域的边缘上多个像素点的坐标位置。需要说明的是，在实际应用中，屏幕切割区域参数可以根据屏幕切割区域的形状等因素确定，本申请实施例对屏幕切割区域参数的形式不做具体限定。
在一些实施例中，第二摄像头埋设在显示屏下方的内部空间。电子设备可以预选存储用于指示第二区域的区域参数，进而能够基于该区域参数确定第二区域，或者，电子设备可以检测用户在显示屏绘制的第二区域。
需要说明的是，对于任何一种第二摄像头设置在显示屏边缘或内部的电子设备，比如前述中“刘海屏”、“水滴屏”和“挖孔屏”以及不同于前述中“刘海屏”、“水滴屏”和“挖孔屏”的其他异形屏，该电子设备都可以通过检测用户在该显示屏绘制的方式来确定第二区域。
需要说明的是，在实际应用中，电子设备也可以不必执行S901来确定第二区域，而是直接执行后续步骤，比如在一些实施例中，第二摄像头设置在电子设备靠近显示屏一侧的面板上，第二区域不能根据屏幕切割区域来确定，因此S901为可选的步骤。
S902，电子设备确定显示屏的最小触控块尺寸。
为了便于通过该提示区域向用户显示信号，也便于通过该提示区域与用户进行交互，从而实现针对摄像头的其他操作，比如关闭等，提示区域的宽度可以基于显示屏 的最小触控块尺寸来确定。
其中，最小触控块可以为显示屏中能够清楚无疑义地接收用户触控操作的最小区域，该最小触控块的尺寸或者确定方式，可以由电子设备接收相关技术人员提交得到。在一些实施例中，电子设备可以获取存储的显示屏的TP行数和TP列数，该显示屏横向像素数除以TP列数所得到的数值即可以为最小触控块的宽度，该显示屏纵向像素数除以TP行数所得到的数值即可以为最小触控块的高度。在另一些实施例中，电子设备可以获取存储的最小触控块尺寸。
需要说明的是，S902可以为可选的步骤，那么在后续步骤中，电子设备可以通过其他方式来确定提示区域的尺寸。
S903，电子设备基于第二区域和最小触控块尺寸，确定第一区域。
由于第二区域为第二摄像头所在的区域，因此为了便于用户感知到提示信号并该提示信号与摄像头联系在一起，提高提示效果，可以将第一区域设置在与第二区域相邻的位置，即第二区域可以与用于确定第一区域的位置。另外，最小触控块可以用于确定第一区域的宽度。因此，基于第二区域和最小触控块尺寸，即可以确定第一区域。
可以理解的是，对于不同的电子设备，由于其第二摄像头的位置不同，第二区域也不同，那么相应的第一区域可以不同，从而呈现出不同电子设备可以包括形态各异的第一区域。
以图20所示的电子设备为例。该电子设备的显示屏为“挖孔屏”，第二摄像头设置在显示屏内部的第二区域1001。第二区域1001为矩形区域，以第二区域为中心，将第二区域1001的宽度向两端延长最小触控块1003的宽度，并将第二区域1001的高度向两端延长最小触控块1003的高度，即可得到同为矩形区域的第一区域1002。
再以图21所示的电子设备为例。该电子设备的显示屏为“刘海屏”，第二摄像头设置在显示屏边缘的第二区域1001。第二区域1001为矩形区域，以第二区域为中心，将第二区域1001的宽度向两端延长最小触控块1003的宽度，并将第二区域1001的高度向远离第二区域1001的一端延长最小触控块1003的高度，即可得到同为矩形区域的第一区域1002。
再以图22所示的电子设备为例。该电子设备的显示屏为异形屏，第二摄像头设置在显示屏边缘右上角的第二区域1001。第二区域1001的形状为不规则形状，第一区域1002可以为圆形。第一区域1002任一处的宽度可以大于或等于最小触控块1003的宽度，第一区域1002任一处的高度可以大于或等于最小触控块1003的高度。
再以图23所示的电子设备为例。第二摄像头设置在电子设备的前面板，并靠近显示屏顶部，所在的第二区域1001为圆形。第一区域1002可以为半圆形，且第一区域1002直线的一边与显示屏顶部重合。第一区域1002可以至少包括一个最小触控块1003。
在一些实施例中，若电子设备省略了S901，即并未确定第二区域，那么电子设备可以在显示屏显示第一边框，其中，第一边框的形状可以是预先设置的，第一边框的尺寸可以是基于最小触控块尺寸确定的。电子设备可以基于第一边框接收用户的第二拖动操作，基于第二拖动操作确定第一区域的位置。也即是，由用户手动设置第一区域的位置。
例如，对于前述图10所示的电子设备，电子设备在未执行S901的情况下，执行 S903时可以如图24所示。电子设备显示第一边框1004，其中，第一边框1004的位置是为显示屏中靠近第二摄像头所在的第二区域1001的一侧，第一边框1004的宽度为最小触控块1003的宽度，第一边框1004的高度为随机数值。电子设备基于第一边框1004接收用户的第二拖动操作重新确定第一边框1004的位置，最终得到如图10所示的第一区域1002。
在一些实施例中，若电子设备省略了S902，即未确定最小触控块尺寸，那么电子设备可以在显示屏显示第二边框，其中，第二边框的形状可以是预先设置的，第二边框的位置可以基于第二区域确定的，第二边框的尺寸可以是随机的尺寸或者预设的尺寸。且在另一些实施例中，电子设备还可以基于第二边框接收用户第二缩放操作，将第二缩放操作缩放后的尺寸确定为第一区域的尺寸。最小触控块尺寸可以被代替为随机的尺寸或预设的尺寸。也即是，由用户手动设置第一区域的尺寸。
在一些实施例中，若电子设备既未执行S901也未执行S902，则可以在显示屏显示第三边框，其中，第三边框的形状可以是预先设置的，第一边框的位置和尺寸都可以是随机的数值或者预设的数值。电子设备可以基于第三边框接收用户的第二拖动操作，基于第二拖动操作确定第一区域的位置；基于第三边框接收用户第二缩放操作，将第二缩放操作缩放后的尺寸确定为第一区域的尺寸。也即是，由用户手动设置第一区域的位置和尺寸，便于在难以自动匹配得到第一区域的情况下，也能够确定第一区域，提高确定第一区域的可靠性。
通过前述S901-S903，电子设备可以通过自动适配，确定第一区域，但在实际应用中，电子设备种类繁多，自动适配所得到的第一区域可能不能完美地与该电子设备的第二区域相匹配，因此，为了提高第一区域的准确性，只要第一区域的位置和尺寸中的至少一个是通过自动适配得到的，电子设备还可以执行下述可选的步骤S904，以使得用户手动对自动适配得到的第一区域进行精确调整。
S904，电子设备基于接收到的第一更新操作，对第一区域进行更新。
其中，第一更新操作用于对第一区域的位置和尺寸中的至少一个进行更新。
在一些实施例中，第一更新操作为对第一区域的第一拖动操作，电子设备可以基于第一拖动操作结束更新第一区域的位置。
在一些实施例中，第一更新操作为对第一区域的第一缩放操作，电子设备可以基于第一缩放操作更新第一区域的尺寸。
在一些实施例中，如果第三区域与第一区域不为同一区域，电子设备还可以按照与S901-S904相似的方式，确定第三区域。
例如，若如前述图15所示的电子设备还确定了不同于第一区域的触控感知区作为第三区域，则可以如图25所示。与图15相比，图25中还包括第三区域1005，且第三区域1005包围第一区域1002和第二区域1001，该电子设备在第一区域1002显示提示信号，如图26所示。其中，在图15所示的显示方式中，第一区域1002既可以用于显示提示信号，还可以用于后续接收用户的相关操作来控制处于打开状态的摄像头。而在图26所示的显示方式中，第一区域1002可以只用于显示提示信号，第一区域1002之外的第三区域1005可以用于后续接收用户的相关操作来控制处于打开状态的摄像头，便于用户操作。
在一些实施例中，若第三区域与第一区域不为同一区域，则第一区域的尺寸可以不必受最小触控块尺寸的限制。
在本申请实施例中，电子设备可以确定第二摄像头所在的第二区域以及显示屏的最小触控块尺寸，并基于第二区域和最小触控块尺寸，自动匹配得到第一区域，提高了确定第一区域的效率。另外，电子设备还可以基于第一更新操作，对自动匹配的第一区域进行更新调整，使得用户能够手动调整通过自动匹配得到的第一区域，提高了第一区域的准确性。
请参照图12，为本申请实施例所提供的一种检测摄像头的状态的方法的流程图，电子设备可以通过提示组件、相机框架和相机驱动之间的交互来完成摄像头状态的检测。需要说明的是，该方法并不以图12以及以下所述的具体顺序为限制，应当理解，在其它实施例中，该方法其中部分步骤的顺序可以根据实际需要相互交换，或者其中的部分步骤也可以省略或删除。该方法包括如下步骤：
S1201，提示组件向相机框架注册摄像头监听事件。
其中，摄像头监听事件可以用于从相机框架感知摄像头打开事件。
电子设备可以通过提示组件向相机框架发送事件注册消息，该事件注册消息中携带注册的事件类型。当相机框架接收到该事件注册消息时，即可基于该事件注册消息，注册该事件类型的事件。
S1202，相机驱动向相机框架发送摄像头调用中断消息。
其中，摄像头调用中断消息用于通知相机框架开始打开摄像头，包括打开第一摄像头或第二摄像头。
在一些实施例中，当某个应用程序需要调用摄像头时，电子设备可以通过该应用程序向相机驱动发送摄像头打开指令，相应的，电子设备若通过相机驱动接收到该摄像头打开指令，则可以向相机框架发送摄像头调用中断消息，并打开摄像头。
在一些实施例中，电子设备还可以通过相机驱动向相机框架通知请求打开摄像头的应用程序的应用标识。
其中，应用标识可以用于识别应用程序。在一些实施例中，该应用标识可以包括该应用程序的应用程序包名、应用程序名称、对应进程的进程ID和图标中的至少一个。当然，在实际应用中，该应用标识也可以包括其他能够用于识别应用程序的信息，本申请实施例对该应用标识的类型不做具体限定。
需要说明的是，电子设备可以通过相机驱动将调用摄像头的应用程序的应用标识，携带在调用中断消息中，也可以通过相机驱动单独向相机框架发送该应用标识。本申请实施例对电子设备通过相机驱动通知提相机框架该应用标识的方式不做具体限定。
S1203，相机框架向提示组件发送摄像头调用消息。
其中，调用消息可以用于指示摄像头被调用并处于打开状态，相应的，若电子设备通过提示组件检测到该调用消息，则可以确定摄像头当前处于打开状态。
在一些实施例中，电子设备还可以相机框架通知提示组件调用摄像头的应用程序的应用标识。
需要说明的是，电子设备可以通过相机框架将调用摄像头的应用程序的应用标识，携带在调用消息中，也可以通过相机框架单独向提示组件发送该应用标识。本申请实 施例对电子设备通过相机框架通知提示组件该应用标识的方式不做具体限定。
在一些实施例中，电子设备可以通过相机框架向提示组件发送第一调用消息，第一调用消息用于指示第一摄像头当前被调用并处于打开状态，相应的，若电子设备通过提示组件检测到第一调用消息，则可以确定第一摄像头当前被调用并处于打开状态。
在一些实施例中，电子设备可以通过相机框架向提示组件发送请求打开第一摄像头的应用程序的应用标识。
相似的，电子设备可以通过相机框架向提示组件发送第二调用消息，第二调用消息用于指示第二摄像头当前被调用并处于打开状态，相应的，若电子设备通过提示组件检测到第二调用消息，则可以确定第二摄像头当前被调用并处于打开状态。另外，电子设备可以通过相机框架向提示组件发送请求打开第二摄像头的应用程序的应用标识。
需要说明的是，若第一摄像头和第二摄像头为同一摄像头，则第二调用消息即为第一调用消息。
在本申请实施例中，电子设备可以通过注册摄像头监听事件的方式，从相机框架感知被打开的摄像头以及打开该摄像头的应用程序，便于及时对用户进行提示。
请参照图14，为本申请实施例所提供的一种电子设备关闭摄像头的方法的流程图。需要说明的是，该方法并不以图14以及以下所述的具体顺序为限制，应当理解，在其它实施例中，该方法其中部分步骤的顺序可以根据实际需要相互交换，或者其中的部分步骤也可以省略或删除。还需要说明的是，图14提供了在检测第一预设控制事件情况下关闭第一摄像头的方法。其中，第一预设控制事件包括第一触控事件和第一感光度下降事件，第一摄像头和第二摄像头为同一摄像头，比如前置摄像头。该方法包括如下步骤：
S1401，电子设备检测第一触控事件。
电子设备可以检测用户的任一触控操作在显示屏上的位置以及操作类型，如果该触控操作是基于第三区域接收到第一触发操作，如果是则可以确定检测到第一触控事件。
S1402，电子设备若检测到第一触控事件，则检测第一感光度下降事件。
电子设备可以基于第一摄像头检测当前的感光度，将检测到的感光度与第一感光度阈值或第二感光度阈值进行比较。在一些实施例中，若检测到的感光度下降且下降的数值变化量大于或等于第一感光度阈值，则可以确定检测到第一感光度下降事件。在一些实施例中，若检测到的感光度下降且下降后的数值小于第二感光度阈值，则可以确定检测到第一感光度下降事件。
S1403，电子设备若检测到第一感光度下降事件，则关闭第一摄像头。
由于已经检测到第一触控事件和第一感光度下降事件，因此可以关闭第一摄像头。
在本申请实施例中，在第一摄像头处于打开状态的情况下，可以依次检测第一触控事件和第一感光度下降事件，并在检测到第一触控事件和第一感光度下降事件时，关闭第一摄像头。由前述可知，第一触控操作可以为沿由第三区域指向第二区域的方向滑动，且至少部分滑动轨迹处于第三区域的滑动操作，而第一摄像头和第二摄像头为同一处于第二区域的摄像头，那么用户可以先按照由第三区域指向第二区域的方向 开始滑动，触发第一触控事件，在滑动过程中逐渐接近并遮挡第一摄像头，进而使得第一摄像头的感光度降低，触发第一感光度下降事件。电子设备按照时间顺序，先在检测到第一摄像头打开时在第一区域显示第一提示信号(第一个条件)，之后再依次检测第一触控事件(第二个条件)和第一感光度下降事件(第三个条件)。当三个条件依次被满足时，电子设备可以关闭第一摄像头。一方面符合用户在感知到第一摄像头开启之后并关闭的操作逻辑，另一方面也减少了误操作的可能。
需要说明的是，本申请实施例仅以先检测第一触控事件再检测第一感光度下降事件的顺序，对电子设备关闭第一摄像头的情况进行说明，并不对检测预设控制事件的检测顺序构成限定。
另外，在前述实施例中，第一区域为显示屏中的部分区域，电子设备可以是通过绘制用户界面(user interface，UI)的方式显示提示信号，该提示信号是由第一区域内多个不同显示状态的像素叠加的结果。而在另一些实施例中，第一区域可以不是显示屏中的部分区域，而是包括至少一个灯光组件的区域，该灯光组件可以包括闪光灯或灯带模组，相应的，提示信号可以只包括光信号，电子设备不需要再进行UI绘制。在后续过程中，电子设备可以仅依据摄像头的感光度变化来确定是否关闭摄像头，而不需要再依赖用户的手势交互。
在一些实施例中，若灯光组件为灯带模组，则该灯带模组可以为环绕第二区域的环形灯带模组。
在一些实施例中，第一光信号可以是由电子设备通过控制第一区域中的闪光灯或灯带模组，按照第一功率输出的光信号。相似的，第三光信号可以是由电子设备通过控制第一区域中的闪光灯或灯带模组，按照第二功率输出的光信号。
其中，第一功率和第二功率可以灯光组件的额定功率或者预设的第一功率阈值，从而使得当灯光组件按照第一功率输出光信号时，可以被认为是处于低功率输出模式，也使得用户能够将第一光信号以及第三光信号，与其他情况下灯光模组发光的情况区别开，提高提示效果。
需要说明的是，若第一摄像头和第摄像头为同一摄像头，则第一功率和第二功率相同。当然，即使第一摄像头和第摄像头不为同一摄像头，第一功率和第二功率也可以相同。
