Description

一种终端及终端拍摄的方法 技术领域
本申请涉及但不限于移动终端技术领域。
背景技术
日常生活中，越来越多的人习惯使用移动终端，例如智能手机、平板电脑等进行拍照，可以随时随地记录生活中的点点滴滴。移动终端在光线充足的情况下进行拍摄都能有出色的表现，但是光线不足的情况下，拍摄出的照片出现模糊的概率较大。
目前市面上的大多数终端生产厂商都会通过适当降低弱光环境下的曝光时间来降低拍照模糊的概率，具体方案是：在普通拍照模式下，为了达到防抖的效果，需要降低曝光时间；而且为了保证拍摄出来的照片的画面亮度，在降低曝光时间的同时还需要提升感光度ISO。提升ISO是指在进光量一定的情况下，提升了光信号的转换倍数，从而在放大了信号的同时也放大了噪声。所以，为了控制拍摄照片的画面噪声，感光度ISO的值也不能提升的太高。

在阅读并理解了附图和详细描述后，可以明白其他方面。
附图概述
图1为本发明实施例提供的一种终端拍摄的方法流程示意图；
图2为本发明实施例提供的另一种终端拍摄的方法流程示意图；
图3为本发明实施例提供的一种终端的结构示意图。
本发明的实施方式
下文中将结合附图对本发明的实施方式进行详细说明。需要说明的是， 在不冲突的情况下，本文中的实施例及实施例中的特征可以相互任意组合。
在附图的流程图示出的步骤可以在诸如一组计算机可执行指令的计算机系统中执行。并且，虽然在流程图中示出了逻辑顺序，但是在某些情况下，可以以不同于此处的顺序执行所示出或描述的步骤。
实施例一
参见图1，为本发明实施例提供的一种终端拍摄的方法流程示意图。图1中示出了本发明实施例提供的一种终端拍摄的方法流程，该方法可以包括以下步骤，即S101～S102：
S101：终端在进入拍摄模式时，获取当前的拍摄场景状态。
可选地，终端获取当前的拍摄场景状态，可以包括：
终端获取当前拍摄环境的光强度，或者当前拍摄环境的光强度拍摄对象的运动速率。
S102：当拍摄场景状态满足预设的拍摄条件时，终端按照预设的像素处理策略将终端的拍摄图像中的相邻像素进行联合处理，得到处理后的拍摄图像。
示例性地，由步骤S101可以得知，拍摄场景状态可以包括当前拍摄环境的光强度，或者还可以包括当前拍摄环境的光强度和拍摄对象的运动速率。
可选地，当拍摄场景状态包括当前拍摄环境的光强度时，拍摄场景状态满足预设的拍摄条件，例如可以包括：当拍摄环境光强度低于第一阈值时，拍摄场景状态满足预设的拍摄条件；
在本实施例中，针对当前拍摄环境的光强度进行获取时，终端可以仅通过光强度相关的阈值来确定是否按照预设的像素处理策略将终端的拍摄图像中的相邻像素进行联合处理。
可选地，当拍摄场景状态包括当前拍摄环境的光强度和拍摄对象的运动速率时，拍摄场景状态满足预设的拍摄条件，例如可以包括：
当拍摄环境光强度低于第二阈值且拍摄对象的运动速率超过第三阈值时，所述拍摄场景状态满足预设的拍摄条件；
当拍摄环境光强度低于第四阈值时，所述拍摄场景状态满足预设的拍摄条件；其中，第二阈值大于第四阈值。
在本实施例中，针对当前拍摄环境的光强度和拍摄对象的运动速率进行获取时，终端就需要对两者进行综合分析来确定是否按照预设的像素处理策略将终端的拍摄图像中的相邻像素进行联合处理。比如：如果环境光强度比较弱，但是拍摄对象处于静止状态，终端通过综合分析后得出常规拍摄也可以拍出清晰的照片，因此，就不需要按照预设的像素处理策略将终端的拍摄图像中的相邻像素进行联合处理；如果环境光强度比较弱，并且拍照对象处于运动状态，或者环境光强度相当弱的时候，终端通过综合分析后得出常规拍摄容易导致拍照模糊，因此，就需要按照预设的像素处理策略将终端的拍摄图像中的相邻像素进行联合处理。
在本实施例中，终端按照预设的像素处理策略将终端的拍摄图像中的相邻像素进行联合处理，得到处理后的拍摄图像，这一过程可以参考用于图像读出的图像读出模式(Binning)的方案，Binning模式在图像读出方面应用的基本思想是：将相邻像元感应的电荷进行相加之后，以一个像素的模式读出。可以分为水平方向Binning和垂直方向Binning，水平方向Binning是将相邻的列的电荷加在一起读出，而垂直方向Binning是将相邻的行的电荷加在一起读出，当行和列同时采用Binning时，图像的纵横比并不改变，当采用2:2Binning，图像的解析度将减少75％。
可选地，基于上述Binning模式的基本思想，终端按照预设的像素处理策略将终端的拍摄图像中的相邻像素进行联合处理得到处理后的拍摄图像，可以包括：
通过2×2的像素模板对拍摄图像进行遍历，并将像素模板范围内的拍摄图像像素相加，得出单个像素；
将像素模板遍历时得到的单个像素按照遍历顺序进行排列，得到处理后的拍摄图像。
可选地，本实施例以2×2的像素模板进行遍历，也就是采用2:2Binning为例进行说明，在实际应用中，设计人员可以根据实际应用场景采用其他的像素模板进行遍历，本实施例对此不作赘述。
以2×2的像素模板进行遍历处理后得到的拍摄图像解析度比原拍摄图像的解析度减少了75％，对于相关技术的终端所配置的八百万甚至更高像素的摄像头来说，减少的解析度并不会影响图像的清晰度，但是由于将拍摄图像中的2×2的像素之和作为单个像素进行输出，从而提高了单个像素的进光量，在单个像素的进光量提升后，终端就可以采用更短的曝光时间和更小的感光度ISO就能够获得与相关技术方案相同甚至更优的降低拍照模糊的效果。
本实施例提供了一种终端拍摄的方法，按照预设的像素模板将像素进行合并后再输出，提高了输出像素的进光量，从而在减少曝光时间的同时只需要提升较小的感光度ISO。
实施例二
基于前述实施例相同的技术构思，参见图2，为图2为本发明实施例提供的另一种终端拍摄的方法流程示意图。图2示出了本发明实施例提供的一种终端拍摄的方法的详细流程，该流程可以包括以下步骤，即S201～S205：
S201：终端在开启拍照功能之后，通过环境光传感器和运动检测技术分别获取当前拍摄环境的光强度和拍摄对象的运动速率。
S202：终端将拍摄环境的光强度和拍摄对象的运动速率分别与预设的光强度相关和拍摄对象运动速率相关的阈值进行比较，确定是否满足预设的拍摄条件。
在本实施例中，可选地，预设的光强度相关和拍摄对象运动速率相关的阈值可以认为是前述实施例所提出的按照预设的像素处理策略将终端的拍摄图像中的相邻像素进行联合处理的预设的拍摄条件，主要的参考条件可以是：如果环境光强度比较弱，但是拍摄对象处于静止状态，终端通过综合分析后得出常规拍摄也可以拍出清晰的照片，因此，就不需要按照预设的像素处理策略将终端的拍摄图像中的相邻像进行联合处理；如果环境光强度比较弱，并且拍照对象处于运动状态，或者环境光强度相当弱的时候，终端通过综合分析后得出常规拍摄容易导致拍照模糊，因此，就需要按照预设的像素处理策略将终端的拍摄图像中的相邻像进行联合处理。
因此，步骤S202的实施就会出现以下几种结果，分别可以为：当拍摄环境光强度低于第二阈值且拍摄对象的运动速率超过第三阈值时，或者当拍摄环境光强度低于第四阈值时，拍摄场景状态满足预设的拍摄条件；可以理解地，第二阈值大于第四阈值；
以及，当拍摄环境光强度和拍摄对象的运动速率没有满足上述条件时，拍摄场景状态不满足预设的拍摄条件。
可选地，当拍摄场景状态满足预设的拍摄条件，可以执行步骤S203；当拍摄场景状态不满足预设的拍摄条件时，可以执行步骤S205。
S203：通过2×2的像素模板对拍摄图像进行遍历，并将像素模板范围内的拍摄图像像素相加，得出单个像素；
S204：将像素模板遍历时得到的单个像素按照遍历顺序进行排列，得到处理后的拍摄图像。
在本实施例中，以2×2的像素模板进行遍历，也就是采用2:2Binning为例进行说明，在实际应用中，设计人员可以根据实际应用场景采用其他的像素模板进行遍历，本实施例对此不作赘述。
S205：按照常规模式进行拍摄。
本实施例提供了一种终端拍摄的方法的详细流程，按照预设的像素模板将像素进行合并后再输出，提高了输出像素的进光量，从而在减少曝光时间的同时只需要提升较小的感光度ISO。
实施例三
基于前述实施例相同的技术构思，参见图3，为本发明实施例提供的一种终端的结构示意图。图3示出了本发明实施例提供的一种终端30的结构，该终端30可以包括：获取单元301、确定单元302和处理单元303。
其中，获取单元301，设置为：当终端进入拍摄模式时，获取当前的拍摄场景状态；
确定单元302，设置为：确定获取单元301获取的拍摄场景状态是否满足预设的拍摄条件；还设置为：当确定出拍摄场景状态满足预设的拍摄条件时，触发处理单元303；
处理单元303，设置为：按照预设的像素处理策略将终端的拍摄图像中的相邻像素进行联合处理，得到处理后的拍摄图像。
在上述方案中，拍摄场景状态包括当前拍摄环境的光强度，或者当前拍摄环境的光强度和拍摄对象的运动速率。
可选地，确定单元302确定拍摄场景状态是否满足预设的拍摄条件，包括：是设置为当拍摄环境光强度低于第一阈值时，拍摄场景状态满足预设的拍摄条件。
可选地，确定单元302确定拍摄场景状态是否满足预设的拍摄条件，包括：是设置为当拍摄环境光强度低于第二阈值且拍摄对象的运动速率超过第三阈值时，拍摄场景状态满足预设的拍摄条件；或者，
是设置为当拍摄环境光强度低于第四阈值时，拍摄场景状态满足预设的拍摄条件；其中，第二阈值大于第四阈值。
可选地，处理单元303，是设置为：通过2×2的像素模板对拍摄图像进行遍历，并将像素模板范围内的拍摄图像像素相加，得出单个像素；以及，
将像素模板遍历时得到的单个像素按照遍历顺序进行排列，得到处理后的拍摄图像。
本实施例提供了一种终端30，按照预设的像素模板将像素进行合并后再输出，提高了输出像素的进光量，从而在减少曝光时间的同时只需要提升较小的感光度ISO。

工业实用性
本发明实施例通过获取终端的当前拍摄场景状态，并且在所获取的拍摄场景状态满足预设的拍摄条件时，按照预设的像素策略将终端的拍摄图像中的相邻像素进行联合处理，实现了将像素进行合并后再输出，提高了输出像素的进光量，从而在减少曝光时间的同时只需要提升较小的感光度ISO。
