具体实施方式
应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。
基于上述问题，本发明提供一种智能电视的拍照方法。
参照图1，图1为本发明智能电视的拍照方法的第一实施例的流程示意图。
在本实施例中，所述智能电视的拍照方法包括：
步骤S10，在智能电视进行拍照时，获取智能电视的摄像头所捕捉环境画面；
步骤S20，根据环境画面确定智能电视当前环境的亮度值；
在本实施例中，在检测到用户打开智能电视上具有拍照功能的APP时，通过与该智能电视关联的摄像头捕捉该智能电视当前的环境画面并将该环境画面显示在该智能电视的取景界面上。当检测到用户按下拍照键进行拍照时，获取该智能电视的摄像头所捕捉的该环境画面，根据该环境画面对应的亮度值确定该智能电视当前环境的亮度值。其中，获取到的该环境画面可以是该智能电视取景界面当前显示的整个环境画面，也可以是该智能电视取景界面显示的整个环境画面中的某一部分画面；该智能电视当前环境的亮度值的区间为[0，255]。
步骤S30，当当前环境的亮度值小于预设值时，逐步增大智能电视的屏幕亮度并显示不同屏幕亮度下的照片预览图像；
在确定智能电视的当前环境的亮度值时，将该智能电视当前环境的亮度值与预设值进行比对，判断该智能电视当前环境的亮度值是否小于该预设值，若该智能电视当前环境的亮度值小于该预设值，则需要根据该智能电视当前环境的亮度值调整该智能电视显示屏的亮度参数，以逐步增大智能电视的屏幕亮度，同时，在该屏幕亮度下显示照片预览图像，该智能电视显示屏的亮度参数包括背光值、亮度值以及对比度。例如，在获取到该智能电视当前环境的亮度值为Lt，该智能电视预设值为L0，将该Lt与该L0进行比较，若该Lt小于该L0，则根据该Lt调整该智能电视显示屏的亮度参数，以逐步增大智能电视的屏幕亮度，并该屏幕亮度下显示照片预览图像。其中，该智能电视预设值的取值区间为[65，75]。
步骤S40，在用户根据照片预览图像选择拍照所需的屏幕亮度后，将屏幕亮度调整为用户所选择的亮度，以供用户在该亮度下拍照。
在用户按下具有拍照功能的APP上的拍照键后，将该摄像头捕捉的各个照片预览图像显示在智能电视的显示界面上，同时提示用户选择是否将该照片预览图像对应的屏幕亮度设置为拍照所需的屏幕亮度，例如，当用户点击某一张照片预览图像时，向用户弹出问题“是否将该照片预览图像对应的屏幕亮度设置为拍照所需的屏幕亮度”，并接受用户的选择，以实现快速确定该智能电视拍照所需的屏幕亮度，或者当用户退出浏览该照片预览图像时，向用户弹出问题“是否将该照片预览图像对应的屏幕亮度设置为拍照所需的屏幕亮度”，并接受用户的选择，又或者在该照片预览图像的结尾处向用户提示问题并接受用户的选择，在用户根据照片预览图像选择拍照所需的屏幕亮度后，根据用户选择的亮度调整拍照所需的屏幕亮度，以供用户在该亮度下拍照。其中，当该摄像头进行拍照的同时该智能电视的显示屏进行闪光，当摄像头拍照完成时，该智能电视的屏幕亮度又恢复到用户选择的该亮度。
需要说明的是，当用户点击某一张照片预览图像时，对于弹出的问题“是否将该照片预览图像对应的屏幕亮度设置为拍照所需的屏幕亮度”，选择的是“否”，则退出当前照片预览图像，用户还可继续浏览各个照片预览图像。
本实施例通过在智能电视进行拍照时，获取智能电视的摄像头所捕捉环境画面，并根据环境画面确定智能电视当前环境的亮度值，当当前环境的亮度值小于预设值时，逐步增大智能电视的屏幕亮度并显示不同屏幕亮度下的照片预览图像，在用户根据照片预览图像选择拍照所需的屏幕亮度后，将屏幕亮度调整为用户所选择的亮度，以供用户在该亮度下拍照。由于在智能电视进行拍照时，获取该智能电视当前环境的亮度值，当获取的该当前环境的亮度值小于预设值时，表明该智能电视当前处于较暗的拍照环境，通过根据该智能电视当前环境的亮度值来调整该智能电视的屏幕亮度至拍照所需的屏幕亮度，以供用户在该亮度下拍照，因此即使智能电视处于较暗的拍照环境，该智能电视的摄像头依然可借助该智能电视的屏幕亮度，拍摄出比较清晰的照片。
进一步的，基于上述第一实施例，请参照图2，提出本发明智能电视的拍照方法的第二实施例的流程示意图，在该第二实施例中，S20之后，该智能电视的拍照方法包括：
步骤S50，当当前环境的亮度值小于预设值时，保存智能电视的当前屏幕亮度，用以在拍照完成后，将智能电视的屏幕亮度调整为当前屏幕亮度。
若该智能电视当前环境的亮度值小于该预设值，说明该智能电视当前所处的拍照环境亮度比较暗，该智能电视的摄像头无法拍摄出比较清晰的照片，则需要将该智能电视的当前屏幕亮度调整为用户所选择的拍照所需的屏幕亮度，并保存该智能电视的当前屏幕亮度，当摄像头基于该拍照所需的屏幕亮度进行拍照的同时该智能电视的显示屏进行闪光，当在该摄像头拍照完成后，将该拍照所需的屏幕亮度恢复为已保存的该智能电视的当前屏幕亮度，使得用户基于已保存的该智能电视的当前屏幕亮度进行其它的操作，如显示照片。例如，若当前环境的亮度值Lt1（Lt1=60）小于该预设值L0（L0=70）时，获取该智能电视的当前屏幕亮度Lt2（Lt2=70），保存该Lt2，并将该Lt2调整为用户所选择的拍照所需的屏幕亮度（Lt3 =80），当该摄像头基于该Lt3进行拍照的同时该智能电视的显示屏进行闪光，当在该摄像头拍照完成后，将拍照所需的屏幕亮度Lt3恢复为该Lt2。
可以理解的是，当该智能电视当前环境越暗，该智能电视当前环境的亮度值就越小，则拍照所需的屏幕亮度就越大，当该智能电视当前环境越亮，该智能电视当前环境的亮度值就越大，则拍照所需的屏幕亮度就越小。
本实施例通过当当前环境的亮度值大于预设值时，保存智能电视的当前屏幕亮度，用以在拍照完成后，将智能电视的屏幕亮度调整为当前屏幕亮度，避免该智能电视的显示屏长时间处于高亮度状态，使得该智能电视显示屏不容易出现老化现象。
进一步的，基于上述第一实施例，请参照图3，提出本发明智能电视的拍照方法的第三实施例的流程示意图，在该第三实施例中，S20之后，该智能电视的拍照方法包括：
步骤S60，当当前环境亮度值不小于预设值时，直接提示用户拍照。
在本实施例中，在当前环境的亮度值大于或者等于预设值时，说明该智能电视当前所处的环境亮度比较亮，则不需调整该智能电视的屏幕亮度，直接提示用户拍照，例如，向用户弹出问题“是否进行拍照”并接受用户的选择。
本实施例通过当当前环境亮度值不小于预设值时，直接提示用户拍照。由于当当前环境亮度值小于预设值时，需要将该智能电视的屏幕亮度调整为拍照所需的屏幕亮度，再提示用户拍照，当当前环境亮度值不小于预设值时，直接提示用户拍照，因此使得智能电视的拍照模式是动态调整的，随着当前环境亮度的改变而改变，从而满足智能电视的摄像头在拍照时对环境亮度的需求，进而改善用户体验。
进一步的，请参照图4，为本发明第一实施例中步骤S20的细化步骤的流程示意图，该步骤S20的细化步骤包括：
步骤S21，获取环境画面中各个像素点的亮度值；
步骤S22，将环境画面中各个像素点的亮度值的平均值作为当前环境的亮度值。
在本实施例中，在智能电视进行拍照时，截取该智能电视当前取景界面显示的环境画面，获取环境画面中各个像素点的亮度值，由于该环境画面中各个像素点的亮度值是由摄像头（感光元件）直接输出的，且没有经过任何处理的图像数据，因此该环境画面中各个像素点的亮度值也可称为原始数据Rawdata。在获取到该原始数据Rawdata时，统计该环境画面中所有的原始数据Rawdata，或者有规则的抽取该环境画面中部分原始数据Rawdata，对该原始数据Rawdata进行累加，对该累加后的原始数据Rawdata求平均值，并将平均值作为该智能电视当前环境的亮度值。
本实施例通过获取环境画面中各个像素点的亮度值，将环境画面中各个像素点的亮度值的平均值作为当前环境的亮度值，使得该智能电视当前环境的亮度值的计算更加的精确。
进一步的，请参照图5，为本发明第一实施例中步骤S40的细化步骤的流程示意图，该步骤S40的细化步骤包括：
步骤S41，切换智能电视屏幕的显示界面为全白画面，并设定其亮度为用户所选择的亮度；
步骤S42，在屏幕亮度为用户所选择的亮度后，提示用户拍照。
在本实施例中，当摄像头基于该拍照所需的屏幕亮度进行拍照的同时切换智能电视屏幕的显示界面为全白画面以增大显示屏的亮度，以供摄像头在全白画面下进行拍照，在拍照的同时该智能电视的显示屏还基于该全白画面进行闪光。其中，该全白画面中的每个像素点的R值、G值以及B值都是255。
本实施例通过切换智能电视屏幕的显示界面为全白画面，并设定其亮度为用户所选择的亮度，在屏幕亮度为用户所选择的亮度后，提示用户拍照。由于将该智能电视显示屏的显示界面切换为全白画面，使得该智能电视显示屏的发光效率是最高，而且不会改变环境的颜色，因此即使该智能电视处于较暗的拍照环境，用户通过该智能电视也可拍摄出比较清晰的照片。
本发明进一步提供一种智能电视的拍照系统。
参照图6，图6为本发明智能电视的拍照系统的第一实施例的功能模块示意图。
在本实施例中，所述智能电视的拍照系统包括：获取模块10、确定模块20、显示模块30以及第一调整模块40。
所述获取模块10，在智能电视进行拍照时，获取智能电视的摄像头所捕捉环境画面；
所述确定模块20，根据环境画面确定智能电视当前环境的亮度值；
在本实施例中，在检测到用户打开智能电视上具有拍照功能的APP时，通过与该智能电视关联的摄像头捕捉该智能电视当前的环境画面并将该环境画面显示在该智能电视的取景界面上。当检测到用户按下拍照键进行拍照时，获取模块10获取该智能电视的摄像头所捕捉的该环境画面，确定模块20根据该环境画面对应的亮度值确定该智能电视当前环境的亮度值。其中，获取模块10获取到的该环境画面可以是该智能电视取景界面当前显示的整个环境画面，也可以是该智能电视取景界面显示的整个环境画面中的某一部分画面；该智能电视当前环境的亮度值的区间为[0，255]。
所述显示模块30，当当前环境的亮度值小于预设值时，逐步增大智能电视的屏幕亮度并显示不同屏幕亮度下的照片预览图像；
在确定模块20确定智能电视的当前环境的亮度值时，显示模块30将该智能电视当前环境的亮度值与预设值进行比对，判断该智能电视当前环境的亮度值是否小于该预设值，若该智能电视当前环境的亮度值小于该预设值，则需要根据该智能电视当前环境的亮度值调整该智能电视显示屏的亮度参数，以逐步增大智能电视的屏幕亮度，同时，在该屏幕亮度下显示照片预览图像，该智能电视显示屏的亮度参数包括背光值、亮度值以及对比度。例如，在获取到该智能电视当前环境的亮度值为Lt，该智能电视预设值为L0，将该Lt与该L0进行比较，若该Lt小于该L0，则根据该Lt调整该智能电视显示屏的亮度参数，以逐步增大智能电视的屏幕亮度，并该屏幕亮度下显示照片预览图像。其中，该智能电视预设值的取值区间为[65，75]。
所述第一调整模块40，在用户根据照片预览图像选择拍照所需的屏幕亮度后，将屏幕亮度调整为用户所选择的亮度，以供用户在该亮度下拍照。
在用户按下具有拍照功能的APP上的拍照键后，显示模块30将该摄像头捕捉的各个照片预览图像显示在智能电视的显示界面上，同时提示用户选择是否将该照片预览图像对应的屏幕亮度设置为拍照所需的屏幕亮度，例如，当用户点击某一张照片预览图像时，向用户弹出问题“是否将该照片预览图像对应的屏幕亮度设置为拍照所需的屏幕亮度”，并接受用户的选择，以实现快速确定该智能电视拍照所需的屏幕亮度，或者当用户退出浏览该照片预览图像时，向用户弹出问题“是否将该照片预览图像对应的屏幕亮度设置为拍照所需的屏幕亮度”，并接受用户的选择，又或者在该照片预览图像的结尾处向用户提示问题并接受用户的选择，第一调整模块40在用户根据照片预览图像选择拍照所需的屏幕亮度后，根据用户选择的亮度调整拍照所需的屏幕亮度，以供用户在该亮度下拍照。其中，当该摄像头进行拍照的同时该智能电视的显示屏进行闪光，当摄像头拍照完成时，该智能电视的屏幕亮度又恢复到用户选择的该亮度。
需要说明的是，当用户点击某一张照片预览图像时，对于弹出的问题“是否将该照片预览图像对应的屏幕亮度设置为拍照所需的屏幕亮度”，选择的是“否”，则退出当前照片预览图像，用户还可继续浏览各个照片预览图像。
本实施例通过在智能电视进行拍照时，获取模块10获取智能电视的摄像头所捕捉环境画面，确定模块20根据环境画面确定智能电视当前环境的亮度值，当当前环境的亮度值小于预设值时，显示模块30逐步增大智能电视的屏幕亮度并显示不同屏幕亮度下的照片预览图像，在用户根据照片预览图像选择拍照所需的屏幕亮度后，第一调整模块40将屏幕亮度调整为用户所选择的亮度，以供用户在该亮度下拍照。由于在智能电视进行拍照时，获取该智能电视当前环境的亮度值，当获取的该当前环境的亮度值小于预设值时，表明该智能电视当前处于较暗的拍照环境，通过根据该智能电视当前环境的亮度值来调整该智能电视的屏幕亮度至拍照所需的屏幕亮度，以供用户在该亮度下拍照，因此即使智能电视处于较暗的拍照环境，该智能电视的摄像头依然可借助该智能电视的屏幕亮度，拍摄出比较清晰的照片。
进一步的，基于上述第一实施例，提出本发明智能电视的拍照系统的第二实施例，在本实施例中，参照图7，所述智能电视的拍照系统还包括：第二调整模块50。
所述第二调整模块50，用于当当前环境的亮度值小于预设值时，保存智能电视的当前屏幕亮度，用以在拍照完成后，将智能电视的屏幕亮度调整为当前屏幕亮度。
若第二调整模块50确定该智能电视当前环境的亮度值小于该智能电视预设值，说明该智能电视当前所处的拍照环境亮度比较暗，该智能电视的摄像头无法拍摄出比较清晰的照片，则需要将该智能电视的当前屏幕亮度调整为用户所选择的拍照所需的屏幕亮度，并保存该智能电视的当前屏幕亮度，当摄像头基于该拍照所需的屏幕亮度进行拍照的同时该智能电视的显示屏进行闪光，当在该摄像头拍照完成后，将该拍照所需的屏幕亮度恢复为已保存的该智能电视的当前屏幕亮度，使得用户基于已保存的该智能电视的当前屏幕亮度进行其它的操作，如显示照片。例如，若当前环境的亮度值Lt1（Lt1=60）小于该预设值L0（L0=70）时，获取该智能电视的当前屏幕亮度Lt2（Lt2=70），保存该Lt2，并将该Lt2调整为用户所选择的拍照所需的屏幕亮度（Lt3 =80），当该摄像头基于该Lt3进行拍照的同时该智能电视的显示屏进行闪光，当在该摄像头拍照完成后，将拍照所需的屏幕亮度Lt3恢复为该Lt2。
可以理解的是，当该智能电视当前环境越暗，该智能电视当前环境的亮度值就越小，则拍照所需的屏幕亮度就越大，当该智能电视当前环境越亮，该智能电视当前环境的亮度值就越大，则拍照所需的屏幕亮度就越小。
本实施例通过当当前环境的亮度值大于预设值时，保存智能电视的当前屏幕亮度，用以在拍照完成后，将智能电视的屏幕亮度调整为当前屏幕亮度，避免该智能电视的显示屏长时间处于高亮度状态，使得该智能电视显示屏不容易出现老化现象。

所述提示模块60，用于当当前环境亮度值不小于预设值时，直接提示用户拍照。
在本实施例中，在当前环境的亮度值大于或者等于预设值时，说明该智能电视当前所处的环境亮度比较亮，则不需调整该智能电视的屏幕亮度，提示模块60直接提示用户拍照，例如，向用户弹出问题“是否进行拍照”并接受用户的选择。
本实施例通过当当前环境亮度值不小于预设值时，直接提示用户拍照。由于当当前环境亮度值小于预设值时，需要将该智能电视的屏幕亮度调整为拍照所需的屏幕亮度，再提示用户拍照，当当前环境亮度值不小于预设值时，直接提示用户拍照，因此使得智能电视的拍照模式是动态调整的，随着当前环境亮度的改变而改变，从而满足智能电视的摄像头在拍照时对环境亮度的需求，进而改善用户体验。
进一步的，基于上述第一实施例，提出本发明智能电视的拍照系统的第四实施例，在本实施例中，参照图9，所述确定模块20包括获取单元21、确定单元22。
所述获取单元21，用于获取环境画面中各个像素点的亮度值；
所述确定单元22，用于将环境画面中各个像素点的亮度值的平均值作为当前环境的亮度值。
在本实施例中，在智能电视进行拍照时，截取该智能电视当前取景界面显示的环境画面，获取单元21获取环境画面中各个像素点的亮度值，由于该环境画面中各个像素点的亮度值是由摄像头（感光元件）直接输出的，且没有经过任何处理的图像数据，因此该环境画面中各个像素点的亮度值也可称为原始数据Rawdata。在获取到该原始数据Rawdata时，统计该环境画面中所有的原始数据Rawdata，或者有规则的抽取该环境画面中部分原始数据Rawdata，确定单元22对该原始数据Rawdata进行累加，对该累加后的原始数据Rawdata求平均值，并将平均值作为该智能电视当前环境的亮度值。
本实施例通过获取环境画面中各个像素点的亮度值，将环境画面中各个像素点的亮度值的平均值作为当前环境的亮度值，使得该智能电视当前环境的亮度值的计算更加的精确。
