第一方面：
在一些实施例中，将显示设备作为显示端与外设设备进行交互时，外设设备仅作为输入设备。显示设备与外设设备的交互内容仅呈现在显示设备中，使得显示设备的内容相对封闭，而显示设备并未与外设设备进行信息共享，使得外设设备在交互过程中不会产生相应变化，这将导致交互场景中内容呈现形式较为单一，用户体验感不高。
为便于用户在利用显示设备进行游戏、唱歌等娱乐交互场景时，能够烘托气氛，提高用户体验，本发明实施例提供一种显示设备，可在播放电视画面、游戏或唱歌等娱乐交互场景下，控制外设设备的显示颜色可以随着用户画面的颜色变化而变化。
为实现外设设备的颜色变化，与显示设备进行交互的外设设备可选用能够发光变色的设备，例如，可变颜色的灯泡、LED灯条等。外设设备的显示颜色随显示设备的用户画面的颜色变化而变化，可以烘托观看显示设备的显示内容的氛围，增加显示内容的呈现形式，提升用户使用显示设备的体验。
图4中示例性示出了根据一些实施例的显示设备的结构框图。为此，本发明实施例提供一种显示设备200，参见图4，包括显示器275、外设设备201和控制器250。显示器275被配置为显示用户画面；外设设备201为可发光变色的设备，被配置为呈现不同的颜色；控制器250与显示器275和外设设备201连接，控制器250用于将显示器275中显示的用户画面的颜色实时同步至外设设备201，使得外设设备201的显示颜色与用户画面的颜色同步更新。
为更加准确地利用外设设备呈现用户画面的颜色，提高气氛烘托的效果，在一些实施例中，同时与显示设备交互的外设设备可为多个。例如，可设置四个外设设备，每个外设设备与显示设备进行连接，连接方式可为有线连接或无线连接，保证在同一局域网中即可。
在采用无线连接方式时，将显示设备连接到路由器，路由器给显示设备分配局域网IP；再将外设设备连接到路由器，路由器给外设设备分配局域网IP。通过路由器即可实现显示设备与每一个外设设备在同一个网段的连接，显示设备可以通过扫描获得连接该局域网的所有外设设备。
图5中示例性示出了根据一些实施例的设备列表的示意图。参见图5，显示设备在进行扫描时，通过在自身所处的局域网中来设置要扫描的所有IP段，通过网络命令进行扫描，获取每个外设设备的IP地址，并将扫描到的每个外设设备显示在设备列表中。若扫描到四个外设设备，则将四个外设设备的名称显示在设备列表中。
基于设备列表，还可对每个外设设备的名称进行修改，也可将其他与颜色呈现不相关的设备在设备列表中删除。
图6中示例性示出了根据一些实施例的显示设备设置多个外设设备的示意图。参见图6，多个外设设备可设置在显示设备的显示器的周围，以设置四个外设设备为例，第一个外设设备201a设置在显示器的上侧，第二个外设设备201b设置在显示器的下侧，第三个外设设备201c设置在显示器的左侧，第四个外设设备201d设置在显示器的右侧。
显示器275周围设置的四个外设设备，可分别呈现用户画面的对应位置所呈现的颜色，即利用第一个外设设备201a呈现用户画面上端的颜色；利用第二个外设设备201b呈现用户画面下端的颜色；利用第三个外设设备201c呈现用户画面左端的颜色；利用第四个外设设备201d呈现用户画面右端的颜色。
每个外设设备对应显示器中用户画面的相应位置，使得每个外设设备201的显示颜色均可与用户画面的对应位置的颜色同步更新，提高外设设备的显示颜色的效果。
图7中示例性示出了根据一些实施例的外设设备颜色跟随画面颜色变化的方法的流程图。本发明实施例提供的一种显示设备，参见图7，其配置的控制器250在执行外设设备颜色跟随画面颜色变化的方法时，被配置为执行下述步骤：
S1、将用户画面划分为多个颜色提取区域，建立每个外设设备与每个颜色提取区域的绑定关系，外设设备的数量与颜色提取区域的数量相同。
由于与显示设备同时交互的外设设备可为多个，每个外设设备的显示设备仅会跟随用户画面的对应位置的颜色变化，因此，为便于准确确定每个外设设备可呈现的用户画面对应位置的颜色，可将用户画面划分成多个颜色提取区域，颜色提取区域用于提供用户画面相应位置所呈现的颜色。
在划分区域时，在一些实施例中，控制器在执行将用户画面划分为多个颜色提取区域，被进一步配置为执行下述步骤：
步骤11、获取显示器呈现的用户画面。
步骤12、按照预设划分规则，对用户画面进行区域划分，得到多个颜色提取区域，每个颜色提取区域不重合。
控制器获取显示器呈现的用户画面，将用户画面按照预设划分规则划分成多个颜色提取区域。预设划分规则可为将用户画面划分成互不重合的多个颜色提取区域，多个颜色提取区域的总和可小于或等于用户画面所呈现的完整区域。
图8中示例性示出了根据一些实施例的颜色提取区域的示意图。参见图8，在将用户画面划分成四个颜色提取区域时，四个颜色提取区域的位置可分别位于用户画面的上、下、左、右四个位置，第一个颜色提取区域A 1位于用户画面的上侧，第二个颜色提取区域A 2位于用户画面的下侧，第三个颜色提取区域A 3位于用户画面的左侧，第四个颜色提取区域A 4位于用户画面的右侧。
颜色提取区域的划分数量与外设设备的设置数量相同，使得颜色提取区域与外设设备呈现一对一的绑定关系，实现由一个外设设备接收一个颜色提取区域的颜色，以便于外设设备可以显示对应区域位置的用户画面的颜色，避免出现混乱，以呈现不同的外设设备显示不同的颜色的效果。
在将外设设备与颜色提取区域建立一对一的绑定关系时，通过触发设备列表中的 目标外设设备名称，将对应的外设设备呈现闪烁状态，以准确确定将要进行绑定的设备为哪一个。而后，可基于用户的个性化设置，将该闪烁的外设设备与其中一个颜色提取区域建立绑定关系。为便于外设设备呈现用户画面的颜色的一致性，可以按照设定位置相同的规则建立外设设备与颜色提取区域的绑定关系。
外设设备的设置位置与颜色提取区域的位置一一对应，例如，将设置在显示器上侧的第一个外设设备201a与位于用户画面上侧的第一个颜色提取区域A 1对应，将设置在显示器下侧的第二个外设设备201b与位于用户画面下侧的第二个颜色提取区域A 2对应，将设置在显示器左侧的第三个外设设备201c与位于用户画面左侧的第三个颜色提取区域A 3对应，将设置在显示器右侧的第四个外设设备201d与位于用户画面右侧的第四个颜色提取区域A 4对应。
S2、获取每个颜色提取区域所呈现画面内容的色彩特征值。
划分出的颜色提取区域用于为对应的外设设备提供显示的颜色，因此，可对每个颜色提取区域中所呈现的画面内容进行颜色提取，确定每个颜色提取区域对应的色彩特征值。色彩特征值可表征对应颜色提取区域的色彩标准值。
在确定色彩特征值时，可直接从每个颜色提取区域中进行提取，还可先获取当前显示器中显示的用户画面(即先截图)，再从截图中提取每个颜色提取区域的色彩特征值。
图9中示例性示出了根据一些实施例的提取色彩特征值的一种方法流程图。在一些实施例中，采用直接提取时，参见图9，控制器在执行获取每个颜色提取区域所呈现画面内容的色彩特征值，被进一步配置为执行下述步骤：
S211、获取每个颜色提取区域所呈现画面内容的颜色直方图。
S212、在每个颜色直方图中提取对应的红色像素合值、绿色像素合值和蓝色像素合值，作为每个颜色提取区域对应的色彩特征值。
由于每个外设设备仅会呈现与其产生绑定关系的颜色提取区域所呈现画面内容的颜色，因此，控制器可直接提取每一个颜色提取区域所呈现画面内容的颜色直方图。颜色直方图是一种颜色特征，其所描述的是不同色彩在整幅图像中所占的比例。
在指定颜色提取区域对应的颜色直方图中提取色彩特征值，包括红色像素合值、绿色像素合值和蓝色像素合值。红色像素合值可为64RColor，是指指定颜色提取区域对应的指定画面内容中所有色彩所呈现的红色像素值的合值；绿色像素合值可为64GColor，是指指定颜色提取区域对应的指定画面内容中所有色彩所呈现的绿色像素值的合值；蓝色像素合值可为64BColor，是指指定颜色提取区域对应的指定画面内容中所有色彩所呈现的蓝色像素值的合值。
每个颜色提取区域均对应一个色彩特征值，例如，第一个颜色提取区域A 1对应色彩特征值C 1(64R 1Color，64G 1Color，64B 1Color)，第二个颜色提取区域A 2对应色彩特征值C 2(64R 2Color，64G 2Color，64B 2Color)，第三个颜色提取区域A 3对应色彩特征值C 3(64R 3Color，64G 3Color，64B 3Color)，第四个颜色提取区域A 4对应色彩特征值C 4(64R 4Color，64G 4Color，64B 4Color)。
图10中示例性示出了根据一些实施例的提取色彩特征值的另一种方法流程图。在一些实施例中，采用截图方式提取时，参见图10，控制器在执行获取每个颜色提取区域所呈现画面内容的色彩特征值，被进一步配置为执行下述步骤：
S221、截取用户画面中所呈现的完整画面。
S222、按照颜色提取区域的划分规则，将完整画面进行划分，确定每个颜色提取区域对应的部分画面内容。
S223、获取每个颜色提取区域所呈现部分画面内容的颜色直方图。
S224、在每个颜色直方图中提取对应的红色像素合值、绿色像素合值和蓝色像素合值，作为每个颜色提取区域对应的色彩特征值。
在采用截图方式提取时，可先对用户画面在某一时刻所呈现的画面进行截屏，得到完整画面。然后分别提取完整画面每个部位的颜色直方图，完整画面中每个部位的确定，可基于划分颜色提取区域的划分规则进行划分，即将完整画面划分成多个部分画面，每隔部位对应一个部分画面，多个部分画面互不重合，多个部分画面的面积总和小于或等于完整画面的总面积。
各个划分得到的部分画面互不重合，可以避免每个部分画面的颜色被影响，进而可以准确提取出相应部分画面的代表颜色，并呈现在外设设备上。例如，如果部分画面B 1与部分画面B 2有重合，而部分画面B 1整体呈现红色，部分画面B 2整体呈现黄色，那么重合后，会导致部分画面B 1的整体颜色呈红色偏黄色，部分画面B 2的整体颜色呈现黄色偏红色，导致最终呈现的颜色并非相应部分画面原本所应呈现的颜色。
完整画面划分成的部分画面数量与颜色提取区域的划分数量相同，位置相同，即若颜色提取区域为四个，位置分别位于用户画面的上、下、左、右四个位置，则完整画面的划分成的部分画面也为四个，四个部分画面的位置也位于完整画面的上、下、左、右四个位置。
完整画面被划分后，每个颜色提取区域对应一个部分画面内容，以将指定部分画面内容所呈现的颜色作为指定颜色提取区域的颜色。在确定指定部分画面内容所呈现的颜色时，可获取该部分画面内容的颜色直方图。
在部分画面内容对应的颜色直方图中提取色彩特征值，包括红色像素合值、绿色像素合值和蓝色像素合值。红色像素合值可为64RColor，是指指定颜色提取区域对应的指定画面内容中所有色彩所呈现的红色像素值的合值；绿色像素合值可为64GColor，是指指定颜色提取区域对应的指定画面内容中所有色彩所呈现的绿色像素值的合值；蓝色像素合值可为64BColor，是指指定颜色提取区域对应的指定画面内容中所有色彩所呈现的蓝色像素值的合值。
将各个部分画面内容对应的颜色特征值作为各个对应的颜色提取区域的颜色特征值，一个部分画面内容的颜色特征值作为一个颜色提取区域的一个色彩特征值，例如，部分画面内容B 1的颜色特征值C 1(64R 1Color，64G 1Color，64B 1Color)为第一个颜色提取区域A 1对应的色彩特征值，部分画面内容B 2的颜色特征值C 2(64R 2Color，64G 2Color，64B 2Color)为第二个颜色提取区域A 2对应的色彩特征值，部分画面内容B 3的颜色特征值C 3(64R 3Color，64G 3Color，64B 3Color)为第三个颜色提取区域A 3对应的色彩特征值，部分画面内容B 4的颜色特征值C 4(64R 4Color，64G 4Color，64B 4Color)为第四个颜色提取区域A 4对应的色彩特征值。
S3、基于每个颜色提取区域的像素面积，将对应的色彩特征值转换成RGB颜色空间的RGB均值。
在确定出每个颜色提取区域的色彩特征值(红色像素合值、绿色像素合值和蓝色 像素合值)后，即可将该色彩特征值转换成RGB颜色空间的RGB均值。在转换时，需利用每个颜色提取区域的像素面积，通过求取RGB颜色空间三原色(红、绿、蓝)均值的方式，确定RGB均值。
在一些实施例中，控制器在执行基于每个颜色提取区域的像素面积，将对应的色彩特征值转换成RGB颜色空间的RGB均值，被进一步配置为执行下述步骤：
步骤31、计算每个颜色提取区域的像素面积。
步骤32、计算红色像素合值与像素面积得到的红色像素均值，计算绿色像素合值与像素面积得到的绿色像素均值，以及，计算蓝色像素合值与像素面积得到的蓝色像素均值，将红色像素均值、绿色像素均值和蓝色像素均值作为RGB颜色空间的RGB均值。
每个颜色提取区域在划分时，可将颜色提取区域划分成矩形、圆形等。例如，在划分成矩形时，可获取指定颜色提取区域两个顶点的像素坐标值，来确定该指定颜色提取区域的像素面积。基于用户画面建立坐标系，坐标原点为用户画面左上角的位置，沿用户画面向右的方向为X轴正向，沿用户画面向下的方向为Y轴正向。
两个顶点选取在矩形的左上点和右下点，在坐标系中，获取指定颜色提取区域对应的矩形的左上点P 1的像素坐标值(X 1，Y 1)和右下点P 2的像素坐标值(X 2，Y 2)，进而确定指定颜色提取区域的像素面积S＝(X 2-X 1)*(Y 2-Y 1)。每个颜色提取区域的像素面积均采用该方法进行计算，可确定出四个颜色提取区域的像素面积分别为S 1、S 2、S 3、S 4。
在计算均值时，由每个颜色提取区域对应的色彩特征值(红色像素合值、绿色像素合值和蓝色像素合值)和对应的像素面积进行求商，即可将色彩特征值转换成RGB颜色空间的RGB均值。
在转换指定颜色提取区域的色彩特征值为RGB均值时，按照式red＝64RColor/S，计算红色像素合值与像素面积的商值，得到的红色像素均值red；按照式green＝64GColor/S，计算绿色像素合值与像素面积的商值，得到的绿色像素均值green；按照式blue＝64BColor/S，计算蓝色像素合值与像素面积的商值，得到的蓝色像素均值blue。最后，将Color.RGB(red，green，blue)作为RGB颜色空间的RGB均值，实现色彩特征值到RGB均值的转换。
例如，在将第一个颜色提取区域A 1对应的色彩特征值C 1(64R 1Color，64G 1Color，64B 1Color)转换为RGB均值时，获取像素面积S 1，按照式red 1＝64R 1Color/S 1，计算红色像素合值与像素面积的商值，得到的红色像素均值red 1；按照式green 1＝64G 1Color/S 1，计算绿色像素合值与像素面积的商值，得到的绿色像素均值green 1；按照式blue 1＝64B 1Color/S 1，计算蓝色像素合值与像素面积的商值，得到的蓝色像素均值blue 1。最后，将Color.RGB(red 1，green 1，blue 1)作为第一个颜色提取区域A 1对应的RGB颜色空间的RGB均值，实现色彩特征值C 1到RGB均值的转换。
在将第二个颜色提取区域A 2对应的色彩特征值C 2(64R 2Color，64G 2Color，64B 2Color)转换为RGB均值时，获取像素面积S 2，按照式red 2＝64R 2Color/S 2，计算红色像素合值与像素面积的商值，得到的红色像素均值red 2；按照式green 2＝64G 2Color/S 2，计算绿色像素合值与像素面积的商值，得到的绿色像素均值green 2；按照式blue 2＝64B 2Color/S 2，计算蓝色像素合值与像素面积的商值，得到的蓝 色像素均值blue 2。最后，将Color.RGB(red 2，green 2，blue 2)作为第二个颜色提取区域A 2对应的RGB颜色空间的RGB均值，实现色彩特征值C 2到RGB均值的转换。
在将第三个颜色提取区域A 3对应的色彩特征值C 3(64R 3Color，64G 3Color，64B 3Color)转换为RGB均值时，获取像素面积S 3，按照式red 3＝64R 3Color/S 3，计算红色像素合值与像素面积的商值，得到的红色像素均值red 3；按照式green 3＝64G 3Color/S 3，计算绿色像素合值与像素面积的商值，得到的绿色像素均值green 3；按照式blue 3＝64B 3Color/S 3，计算蓝色像素合值与像素面积的商值，得到的蓝色像素均值blue 3。最后，将Color.RGB(red 3，green 3，blue 3)作为第三个颜色提取区域A 3对应的RGB颜色空间的RGB均值，实现色彩特征值C 3到RGB均值的转换。
在将第四个颜色提取区域A 4对应的色彩特征值C 4(64R 4Color，64G 4Color，64B 4Color)转换为RGB均值时，获取像素面积S 4，按照式red 4＝64R 4Color/S 4，计算红色像素合值与像素面积的商值，得到的红色像素均值red 4；按照式green 4＝64G 4Color/S 4，计算绿色像素合值与像素面积的商值，得到的绿色像素均值green 4；按照式blue 4＝64B 4Color/S 4，计算蓝色像素合值与像素面积的商值，得到的蓝色像素均值blue 4。最后，将Color.RGB(red 4，green 4，blue 4)作为第四个颜色提取区域A 4对应的RGB颜色空间的RGB均值，实现色彩特征值C 4到RGB均值的转换。
S4、基于绑定关系，将每个颜色提取区域的RGB均值发送至对应的外设设备，由外设设备呈现RGB均值对应的颜色。
在确定出每个颜色提取区域的RGB均值后，即可将该RGB均值发送至对应的外设设备进行显示。每个颜色提取区域与外设设备存在一一对应的绑定关系，因此，控制器可将每个颜色提取区域的RGB均值基于绑定关系发送至对应的外设设备。
例如，将第一个颜色提取区域A 1对应的RGB均值Color.RGB(red 1，green 1，blue 1)发送至第一个外设设备201a，由第一个外设设备201a呈现RGB均值Color.RGB(red 1，green 1，blue 1)对应的颜色。将第二个颜色提取区域A 2对应的RGB均值Color.RGB(red 2，green 2，blue 2)发送至第二个外设设备201b，由第二个外设设备201b呈现RGB均值Color.RGB(red 2，green 2，blue 2)对应的颜色。将第三个颜色提取区域A 3对应的RGB均值Color.RGB(red 3，green 3，blue 3)发送至第三个外设设备201c，由第三个外设设备201c呈现RGB均值Color.RGB(red 3，green 3，blue 3)对应的颜色。将第四个颜色提取区域A 4对应的RGB均值Color.RGB(red 4，green 4，blue 4)发送至第四个外设设备201d，由第四个外设设备201d呈现RGB均值Color.RGB(red 4，green 4，blue 4)对应的颜色。
控制器在将RGB均值发送至对应的外设设备时，可先将RGB均值打包成网络包的形式进行发送。外设设备接收到网络包，进行解析，得到对应的颜色值，并将该颜色进行显示，改变该外设设备的显示颜色。
在一些实施例中，控制器每隔300毫秒获取一次指定颜色提取区域的色彩特征值，并转换成RGB均值，再由外设设备显示RGB均值对应的颜色，使得用户画面与外设设备共同所显示的颜色呈现渐变颜色的效果，这样可以保证用户画面与外设设备的显示颜色同步显示，实现外设设备的显示颜色随用户画面的改变而改变。
由以上技术方案可知，本发明实施例提供的一种显示设备，控制器将用户画面划分为多个颜色提取区域，建立每个外设设备与每个颜色提取区域的绑定关系，获取每 个颜色提取区域所呈现画面内容的色彩特征值；基于每个颜色提取区域的像素面积，将对应的色彩特征值转换成RGB颜色空间的RGB均值；将每个颜色提取区域的RGB均值发送至对应的外设设备，由外设设备呈现RGB均值对应的颜色。可见，本发明实施例提供的显示设备，通过获取用户画面的颜色，将该颜色发送至外设设备进行显示，使得外设设备的显示颜色可以随着用户画面的颜色变化而变化，增加显示内容的呈现形式，提升用户使用显示设备的体验。

图11为本申请根据示例性实施例示出的显示设备外观示意图，如图11所示，该显示设备包括摄像头231和一个摄像头呼吸灯2311，摄像头呼吸灯可以在显示设备控制器的控制下呈现出不同的灯光效果，以指示出摄像头的工作状态。例如，摄像头呼吸灯持续高电平输入时，其将呈现出常亮的灯光效果，持续低电平输入时，其将呈现出常灭的灯光效果，高电平与低电平交替输入时，其将呈现闪烁的灯光效果。
图12为本申请根据另一示例性实施例示出的显示设备外观示意图，与图11所示显示设备不同的是，该显示设备包括231和多个摄像头呼吸灯2311。应当理解，该多个摄像头呼吸灯可以为显示设备控制器所同步控制，也可以为显示设备控制器所单独控制。
需要说明的是，摄像头可以是显示设备内置的摄像头，也可以是通过外部装置接口与显示设备控制器连接的外置摄像头。摄像头呼吸灯可以是与显示设备内置的呼吸灯，也可以是通过外部装置接口与显示设备连接的外置呼吸灯。
在一些实施例中，为使摄像头应用可以在启动、使用及关闭摄像头时，摄像头呼吸灯能够呈现出摄像头应用所需的灯光效果，控制器250被配置为：获取呼吸灯控制参数，该呼吸灯控制参数是与摄像头应用在使用摄像头时所需的灯光效果对应的；根据呼吸灯控制参数控制摄像头呼吸灯，以使摄像头呼吸灯呈现出摄像头应用所需的灯光效果。
在上述实施例中，摄像头应用是指可以使用摄像头的应用，如“魔镜”应用、“嗨见”应用、“K歌”应用等等。
在上述实施例中，呼吸灯控制参数可以是用于指示控制摄像头呼吸灯常亮的参数，如预先定义“255”为指示控制摄像头呼吸灯常亮的参数，可以是用于指示控制摄像头呼吸灯闪烁及闪烁频率的参数，如预先定义“1～5”为指示控制摄像头呼吸灯以1～5次/秒闪烁的参数，还可以是用于指示控制摄像头呼吸灯关闭的参数，如预先定义“0”为指示控制摄像头呼吸灯关闭的参数。
在一些实施例中，控制器250直接与摄像头呼吸灯电连接，从而，控制器250可以根据获取到的呼吸灯控制参数，控制摄像头呼吸灯的高/低电平输入，以使摄像头呼吸灯呈现出与呼吸灯控制参数对应的灯光效果。
在另一些实施例中，摄像头具有单独的单片机，控制器250与该单片机连接，单片机与摄像头呼吸灯连接，从而，通过该单片机完成对摄像头呼吸灯的控制。在一些实施例中，该用于直接控制摄像头呼吸灯的单片机又被称为呼吸灯控制模块。在这些实施例中，控制器250获取到呼吸灯控制参数后，根据呼吸灯控制参数生成呼吸灯控制指令，并将呼吸灯控制指令发送给呼吸灯控制模块；呼吸灯控制模块，根据接收到的呼吸灯控制指令，通过控制摄像头呼吸灯的高/低电平输入，控制摄像头呼吸灯。
为了使摄像头应用可以控制摄像头呼吸灯呈现出其所需的灯光效果，由框架层中的摄像头控制服务(CameraControl服务)提供一个用于应用传入呼吸灯控制参数的接口，进而，应用在需要控制摄像头呼吸灯时，通过调用该接口即可传入与其所需的灯光效果对应的呼吸灯控制参数，当该接口被调用时，摄像头控制服务根据传入的呼吸灯控制参数生成呼吸灯控制指令，并将呼吸灯控制指令发送给呼吸灯控制模块。这样，任意摄像头应用均可控制摄像头呼吸灯呈现出其所需的灯光效果。
在一些实施例中，控制器250被配置为：响应于摄像头启动指令，在启动摄像头的同时，控制所述摄像头呼吸灯开启，并在所述摄像头呼吸灯的开启时长达到预设时长时，控制所述摄像头呼吸灯关闭。这样，在启动摄像头的场景中，持续预设时长(如2秒)的灯光点亮效果可以使用户在视觉上感知到摄像头的启动过程，消除用户困扰，提升用户体验。结合前述实施例，在一些更为具体的实施例中，摄像头应用在接收到触发摄像头启动指令的用户输入时，可以通过调用框架层中的CameraService服务启动摄像头，与此同时，根据摄像头控制服务所提供的上述接口传入第一控制参数；摄像头控制服务接收到摄像头应用传入的第一控制参数后，将根据第一控制参数生成呼吸灯开启指令，并将呼吸灯开启指令发送给呼吸灯控制模块；呼吸灯控制模块则响应于接收到呼吸灯开启指令，控制摄像头呼吸灯开启。在预设时长后，摄像头应用再次根据摄像头控制服务所提供的上述接口传入第二控制参数；摄像头控制服务接收到摄像头应用传入的第二控制参数后，将根据第二控制参数生成呼吸灯关闭指令，并将呼吸灯关闭指令发送给呼吸灯控制模块；呼吸灯控制模块则响应于接收到呼吸灯关闭指令，控制摄像头呼吸灯关闭。
示例性的，第一控制参数可如前述实施例提及的“255”，第二控制参数可如前述实施例提及的“0”。
图13为本申请根据示例性实施例示出的摄像头呼吸灯控制场景示意图，如图13所示，当显示设备显示应用中心界面时，用户可以通过语音、按键、手势等任意形式输入用于启动应用中心中“魔镜”应用的指令，显示设备控制器响应于用户输入的该指令，启动“魔镜”应用，“魔镜”应用启动成功后，通过调用框架层中的CameraService服务启动摄像头，与此同时，根据摄像头控制服务所提供的上述接口传入呼吸灯控制参数，以由摄像头控制服务根据传入的呼吸灯控制参数，配合呼吸灯控制模块，开启摄像头呼吸灯，并在预设时间长关闭摄像头呼吸灯。进而，为用户展示出“魔镜”应用启动摄像头的同时，摄像头呼吸灯持续预设时长的灯光点亮效果。在一些实施例中，控制器250被配置为：响应于触发图像拍摄指令的用户输入，在控制摄像头拍摄图像的同时，控制摄像头呼吸灯以第一特定频率闪烁，例如闪烁1次。这样，在拍照场景中，用户每按下一次快门键，都将伴随着一定频率的呼吸灯闪烁，可以使用户在视觉上感知到摄像头拍摄的时间截点，消除用户困扰，提升用户拍照体验。
在另一些实施例中，控制器250被配置为：响应于触发视频录制开始指令的用户输入，在控制摄像头录制视频的同时，控制摄像头呼吸灯以第二特定频率闪烁，例如每秒闪烁5次；响应于触发视频录制开始指令的用户输入，在控制摄像头结束录制视频的同时，控制摄像头呼吸灯关闭。这样，在录像场景中，在摄像头开始录制一直到结束录制的过程中，始终伴随着一定频率的呼吸灯闪烁，可以使用户在视觉上感知到摄像头的录制过程，消除用户困扰，提升用户录像体验。
需要说明的是，上述触发图像拍摄指令的用户输入，包括但不限于指示开始拍摄图片 的按键输入、语音输入、手势输入等。上述触发视频录制开始指令及视频录制结束指令的用户输入，包括但不限于指示开始录制及结束录制的按键输入、语音输入、手势输入等。
结合前述实施例，在一些更为具体的实施例中，当摄像头应用接收到触发图像拍摄指令的用户输入时，根据摄像头控制服务所提供的上述接口传入第一频率参数；摄像头控制服务根据摄像头应用传入的第一频率参数生成呼吸灯闪烁指令，并将呼吸灯闪烁指令发送给呼吸灯控制模块；呼吸灯控制模块，用于根据呼吸灯闪烁指令控制摄像头呼吸灯按照第一特定频率闪烁。当摄像头应用接收到触发视频录制开始指令的用户输入时，根据摄像头控制服务所提供的上述接口传入第二频率参数；摄像头控制服务根据摄像头应用传入的第二频率参数生成呼吸灯闪烁指令，并将呼吸灯闪烁指令发送给呼吸灯控制模块；呼吸灯控制模块，用于根据呼吸灯闪烁指令控制摄像头呼吸灯按照第二特定频率闪烁。当摄像头应用接收到触发视频录制结束指令的用户输入时，根据摄像头控制服务所提供的上述接口传入第二控制参数；摄像头控制服务根据摄像头应用传入的第二控制参数生成呼吸灯关闭指令，并将呼吸灯关闭指令发送给呼吸灯控制模块；呼吸灯控制模块响应于接收到呼吸灯关闭指令，控制摄像头呼吸灯关闭。
示例性的，第一频率参数和第二频率参数可以是上述实施例提及的“1～5”中的任意一个，如第一频率参数为“1”，这样，当摄像头应用接收到指示拍摄图片的用户指令时，将会控制摄像头呼吸灯闪烁一次。
图14为本申请根据示例性实施例示出的摄像头呼吸灯控制场景示意图，如图14所示，显示设备显示的前台应用界面为“魔镜”应用提供的摄像头预览界面，在显示该界面时，用户可以通过语音、按键、手势等任意形式输入用于触发图像拍摄的指令；显示设备控制器响应于用户输入的该指令，当用户输入该指令后，显示设备通过摄像头拍摄一张图片，同时，摄像头呼吸灯闪烁一次；若用户再次输入触发图像拍摄的指令，显示设备通过摄像头再拍摄一张图片，同时，摄像头呼吸灯再闪烁一次；这样，在拍照场景中，用户每按下一次快门键，都将伴随着一定频率的呼吸灯闪烁，可以使用户在视觉上感知到摄像头拍摄的时间截点，消除用户困扰，提升用户拍照体验。
图15为本申请根据示例性实施例示出的摄像头呼吸灯控制场景示意图，如图15所示，显示设备显示的前台应用界面为“魔镜”应用提供的摄像头预览界面，在显示该界面时，用户可以通过语音、按键、手势等任意形式输入用于触发开始视频录制的指令；显示设备控制器响应于用户输入的该指令，当用户输入该指令后，显示设备通过摄像头录制视频，在录制视频的过程中，摄像头呼吸灯将以每秒5次的频率持续闪烁，直到视频录制结束，即直到用户输入用于结束录制视频的指令。这样，在录像场景中，在摄像头开始录制一直到结束录制的过程中，始终伴随着一定频率的呼吸灯闪烁，可以使用户在视觉上感知到摄像头的录制过程，消除用户困扰，提升用户录像体验。在一些实施例中，控制器250被配置为：响应于接收到通话请求，控制所述摄像头呼吸灯以特定频率闪烁。其中，通话请求可以是语音通话请求，也可以是视频通话请求。这样，当通话应用接收到好友设备发送的通话请求时，通过控制摄像头呼吸灯以特定频率闪烁，达到提醒用户的目的。
具体实现时，当通话应用接收到通话请求时，根据摄像头控制服务所提供的上述接口传入特定的频率参数；摄像头控制服务根据摄像头应用传入的频率参数生成呼吸灯闪烁指令，并将呼吸灯闪烁指令发送给呼吸灯控制模块；呼吸灯控制模块，用于根据呼吸灯闪烁指令控制摄像头呼吸灯以特定频率闪烁。
图16为本申请根据示例性实施例示出的摄像头呼吸灯控制场景示意图，如图16所示，显示设备显示接收到通话请求时的用户界面。在显示设备接收到通话请求时起，到显示设备拒绝或接受该通话请求的过程中，摄像头呼吸灯将以特定频率持续闪烁，从而达到提醒用户的目的。
由以上实施例可知，本申请提供一种显示设备，该显示设备包括摄像头、摄像头呼吸灯和控制器；所述控制器，与所述摄像头呼吸灯连接，用于获取呼吸灯控制参数，所述呼吸灯控制参数与应用在使用所述摄像头时所需的灯光效果对应；根据所述呼吸灯控制参数控制所述摄像头呼吸灯；所述摄像头呼吸灯，用于呈现应用所需的灯光效果。本申请显示设备中，其摄像头配置有呼吸灯功能，摄像头呼吸灯可以在摄像头工作时呈现出应用所需的灯光效果，提升用户体验。在本申请提供的显示设备上，任意摄像头应用均可根据需求控制摄像头呼吸灯呈现出其所需的灯光效果，从而达到提醒用户、提升用户体验的目的。
