具体实施方式
为了保证闪光灯的光，能够被手机中摄像头的芯片捕捉到，现有技术通常会延长闪光灯的开启时间，例如，如图1所示，闪关灯的驱动时间涵盖3帧图像，且该3帧图像均完全被曝光，可以从3帧图像中选取最佳图像进行输出，这种方式下，闪光灯发光的时间通常会在200ms左右。进一步地，随着闪光灯开启时间的延长，温度会增加；图2为闪光灯的亮度随温度变化的变化关系示意图，从图2所示的变化示意图中可以看出，随着温度的增加亮度反而降低，也就是说，现有3帧图像的闪光灯开启方式，会导致闪光灯亮度降低，即3帧图像会出现亮度不同，亮度不均匀的问题，难以从3帧图像中选取中最佳图像。因此，为解决上述问题，本公开实施例提供了一种控制方法及处理装置。为了能够更加详尽地了解本公开的特点与技术内容，下面结合附图对本公开的实现进行详细阐述，所附附图仅供参考说明之用，并非用来限定本公开。但是应该理解，这些描述只是示例性的，而并非要限制本公开的范围。此外，在以下说明中，省略了对公知结构和技术的描述，以避免不必要地混淆本公开的概念。

实施例一
本实施例提供了一种控制方法，所述方法应用于处理装置中，所述处理装置可以具体为图像采集装置，如摄像头，或为包含有所述图像采集装置的具体处理装置，例如，手机、平板电脑等电子设备。这里，以处理装置是摄像头为例对本实施例做解释。本实施例通过在摄像头的芯片中增加一特殊的闪光灯同步信号，来控制闪光灯的开启时间，进而将闪光灯的开 启时间从200ms左右缩短到10ms以内，实现缩短闪光灯的开启时间的目的。进一步地，由于本实施例缩短了闪光灯的开启时间，基于如图2所示的原理可以确定出，本实施例在缩短闪光灯的开启时间的同时，能够提升闪光灯的亮度，进而避免了由于闪光灯开启时间较长而导致的亮度不均匀的问题，为提升用户体验奠定了基础。
图3为本公开实施例一控制方法的实现流程示意图；如图3所示，所述方法包括：
步骤301：获取图像的输出时间信息，所述输出时间信息表征图像采集装置在对目标对象进行采集时所述图像采集装置输出目标图像的时间信息。
具体地，图4为本公开实施例提供的控制方法对闪光灯进行控制的时序图，以下结合图4对本公开所述的输出时间信息、曝光时间信息以及开启时间信息做进一步详细解释。
根据本公开的实施例所述输出时间信息可以具体对应图4所示的图像输出时间，进一步地，从图4的图像输出时间中可以看出，所述输出时间信息可以具体包括每帧图像的输出时间，以及相邻两帧图像进行输出时的间隔时间，如A和B两点之间即为两帧图像进行输出的时间间隔。
步骤302：获取图像的曝光时间信息，所述曝光时间信息表征所述图像采集装置在对所述目标对象进行采集时所述图像采集装置的曝光时间信息。
继续以图4为例，所述曝光时间信息可以具体对应图4所示的曝光时间，从图4的曝光时间中可以看出，所述曝光时间信息包含从第一行开启扫描的时间至最后一行扫描结束的时间。根据本公开的实施例，A和B两点之间的曝光时间内一帧图像的内容才会全部被曝光，也即A和B两点之间的曝光时间具体为一帧图像中从第一行扫描结束之前到最后一行扫描开始之后所对应的时间段，在该时间段内，该帧图像的全部内容才会被全部曝光。
步骤303：基于所述输出时间信息以及所述曝光时间信息，产生用于控制闪光灯处于工作状态的开启时间信息，所述开启时间信息表征所述图像采集装置在对目标对象进行采集时开启闪光灯处于工作状态的时间信息。
根据本公开的实施例，所述开启时间信息所对应的时间段可以具体位于输出时间信息所包含的相邻两帧目标图像之间间隔的第一时间段，例如，第一时间段可以具体为图4所示的输出时间对应的A和B两点之间的时间段。进一步地，所述开启时间信息所对应的时间段还位于曝光时间信息所包含的一帧图像中从第一行扫描结束之前到最后一行扫描开始之后的第二时间段，例如，第二时间段可以具体为图4所示的曝光时间对应的A和B两点之间的时间段。也就是说，所述开启时间信息位于曝光时间对应的A和B两点之间的时间段内，以及位于输出时间对应的A和B两点之间的时间段。
根据本公开的实施例，所述曝光时间对应的A和B两点之间的时间段与输出时间对应的 A和B两点之间的时间段可以相同(如图4所示)，也可能不相同，例如，输出时间对应的A和B两点之间的时间段大于曝光时间对应的A和B两点之间的时间段，即前者与后者不同，但前者包含后者。
步骤304：输出所述开启时间信息，以使得所述闪光灯在所述开启时间信息所对应的时间段内处于工作状态。
根据本公开的实施例，若闪光灯的开启时间变的很短，则难以通过软件精确控制，基于此，可以采用如下方式输出开启时间信息，即利用所述图像采集装置的管脚将所述开启时间信息的脉冲信号输出，以使得所述闪光灯在所述开启时间信息所对应的时间段内处于工作状态。例如，可以在摄像头的芯片中增加一个控制闪光灯的管脚，利用该控制闪光灯的管脚来控制闪光灯在所述开启时间信息所对应的时间段内处于工作状态，进而解决了闪光灯开启时间较短而无法使用软件进行精确控制的问题。
根据本公开的实施例，利用图像采集装置在对目标对象进行采集时图像的输出时间信息，以及图像的曝光时间信息来确定出控制闪光灯处于工作状态的开启时间信息，由于确定出的开启时间信息是基于输出时间信息以及开启时间信息而确定的，所以，确定出的开启时间信息可以控制处于输出时间信息以及曝光时间信息所对应的时间段内，如此，为缩短闪光灯的开启时间奠定了基础，进而为避免由于闪光灯开启时间较长而导致的亮度不均匀的问题，为提升用户体验奠定了基础。
实施例二
基于实施例一所述的方法，本实施例提供了一种确定开启时间信息的具体方法，即利用逻辑门电路来确定开启时间信息，具体地，将所述输出时间信息以及所述曝光时间信息输入所述图像采集装置的逻辑门电路，进而通过所述逻辑门电路生成所述开启时间信息。
根据本公开的实施例，所述逻辑门电路至少包括逻辑与门电路；对应地，确定开启时间信息的方法则可具体为：将从感光组件中获取到的曝光时间信息输入至逻辑与门电路中，以及将从图像输出接口中获取到的输出时间信息输入至逻辑与门电路中；利用所述逻辑与门电路对所述曝光时间信息和所述输出时间信息进行取小处理，得到同时处于所述曝光时间信息所对应的时间段内以及所述输出时间信息所对应的时间段内的目标时间范围；从所述目标时间范围中选取出开启时间信息。
结合图5和图6所示，对本实施例做进一步详细说明。
图5为现有图像采集装置的芯片内部结构示意图。如图5所示，现有图像采集装置的芯片内部主要包括感光组件，也即Image sensor core，用于将光信号转换为电信号；图像处理组 件，也即Image sensor process，用于将感光组件产生的电信号暂时存储；图像输出接口，也即Image output interface，用于按照输出的协议，将图像按照以MIPI协议进行输出。
图6为本公开实施例图像采集装置的芯片内部结构示意图，对比图5和图6可以看出，本实施例在现有图像采集装置的芯片上增加逻辑门电路以及管脚，如，在时间产生和系统控制逻辑中增加管脚，如此，来控制逻辑门电路向感光组件中的Row select中去获取曝光时间信息，以及向图像输出接口的MIPI去获取输出时间信息，进而通过自身的逻辑运算得到开启时间信息，并利用管脚输出该开启时间信息，如此，实现缩短闪光灯的开启时间的目的，且由于闪光灯的开启时间是基于曝光时间信息确定出的，所以，能够确保闪光灯的开启时间内目标图像的全部内容均被曝光。
根据本公开的实施例，图6所示的逻辑门电路可以具体为逻辑与电路，即从输出时间信息和曝光时间信息中选取出两者均包含的最短时间段，并从该最短时间段中选取出开启时间信息。
实施例三
本实施例提供了一种处理装置，所述处理装置可以具体为图像采集装置，如摄像头，或为包含有所述图像采集装置的具体处理装置，例如，手机、平板电脑等电子设备。以处理装置是摄像头为例对本实施例做解释，即本实施例通过在摄像头的芯片中增加一特殊的闪光灯同步的信号，来控制闪光灯开启时间，进而将闪光灯的开启时间从200ms左右缩短到10ms以内，实现缩短闪光灯的开启时间的目的。进一步地，由于本实施例缩短了闪光灯的开启时间，所以，基于如图2所示的原理可以确定出，本实施例在缩短闪光灯的开启时间的同时，能够提升闪光灯的亮度，进而避免了由于闪光灯开启时间较长而导致的亮度不均匀的问题，为提升用户体验奠定了基础。
如图7所示，所述处理装置包括图像采集组件71和处理器72。其中：
图像采集组件71，用于获取图像的输出时间信息，所述输出时间信息表征图像采集装置在对目标对象进行采集时所述图像采集装置输出目标图像的时间信息；以及用于获取图像的曝光时间信息，所述曝光时间信息表征所述图像采集装置在对所述目标对象进行采集时所述图像采集装置的曝光时间信息。
处理器72，用于基于所述输出时间信息以及所述曝光时间信息，产生用于控制闪光灯处于工作状态的开启时间信息，所述开启时间信息表征所述图像采集装置在对目标对象进行采集时开启闪光灯处于工作状态的时间信息。
对应地，所述图像采集组件71，还用于输出所述开启时间信息，以使得所述闪光灯在所 述开启时间信息所对应的时间段内处于工作状态。
具体地，图4为本公开实施例控制方法对闪光灯进行控制的时序图，以下结合图4对本公开所述的输出时间信息、曝光时间信息以及开启时间信息做进一步详细解释。
根据本公开的实施例，所述输出时间信息可以具体对应图4所示的图像输出时间，进一步地，从图4的图像输出时间中可以看出，所述输出时间信息可以具体包括每帧图像的输出时间，以及相邻两帧图像进行输出时的间隔时间，如A和B两点之间即为两帧图像进行输出的时间间隔。
继续以图4为例，所述曝光时间信息可以具体对应图4所示的曝光时间，从图4的曝光时间中可以看出，所述曝光时间信息包含从第一行开启扫描的时间至最后一行扫描结束的时间。根据本公开的实施例，A和B两点之间的曝光时间内一帧图像的内容才会全部被曝光，也即A和B两点之间的曝光时间具体为一帧图像中从第一行扫描结束之前到最后一行扫描开始之后所对应的时间段，该时间段内，该帧图像的全部内容才会被全部曝光。
在一具体实施例中，所述开启时间信息所对应的时间段属于相邻两帧目标图像之间间隔的第一时间段且属于一帧图像中从第一行结束之前到最后一行开始之后的第二时间段。例如，第一时间段可以具体为图4所示的输出时间对应的A和B两点之间的时间段，第二时间段可以具体为图4所示的曝光时间对应的A和B两点之间的时间段。也就是说，所述开启时间信息位于曝光时间对应的A和B两点之间的时间段内，以及位于输出时间对应的A和B两点之间的时间段。
根据本公开的实施例，所述曝光时间对应的A和B两点之间的时间段与输出时间对应的A和B两点之间的时间段可以相同(如图4所示)，也可能不相同，例如，输出时间对应的A和B两点之间的时间段大于曝光时间对应的A和B两点之间的时间段，即前者与后者不同，但前者包含后者。
根据本公开的实施例，所述处理器72，还用于将所述输出时间信息以及所述曝光时间信息输入所述图像采集装置的逻辑门电路，并通过所述逻辑门电路生成所述开启时间信息。
根据本公开的实施例，所述逻辑门电路至少包括逻辑与门电路；对应地，所述处理器72，还用于：将从感光组件中获取到的曝光时间信息输入至逻辑与门电路中，以及将从图像输出接口中获取到的输出时间信息输入至逻辑与门电路中；利用所述逻辑与门电路对所述曝光时间信息和所述输出时间信息进行取小处理，得到同时处于所述曝光时间信息所对应的时间段内以及所述输出时间信息所对应的时间段内的目标时间范围；从所述目标时间范围中选取出开启时间信息。
根据本公开的实施例，若闪光灯的开启时间变的很短，则难以通过软件精确控制，基于 此，可以采用如下方式输出开启时间信息，即，所述图像采集组件71，还用于利用管脚将所述开启时间信息的脉冲信号输出，以使得所述闪光灯在所述开启时间信息所对应的时间段内处于工作状态。
结合图5和图6所示，对本实施例做进一步详细说明。
图5为现有图像采集装置的芯片内部结构示意图，如图5所示，现有图像采集装置的芯片内部主要包括感光组件，也即Image sensor core，用于将光信号转换为电信号；图像处理组件，也即Image sensor process，用于将感光组件产生的电信号暂时存储；图像输出接口，也即Image output interface，用于按照输出的协议，将图像按照以MIPI协议进行输出。
图6为本公开实施例图像采集装置的芯片内部结构示意图，对比图5和图6可以看出，本实施例在现有图像采集装置的芯片上增加逻辑门电路以及管脚，如，在时间产生和系统控制逻辑中增加管脚，如此，来控制逻辑门电路向感光组件中的Row select中去获取曝光时间信息，以及向图像输出接口的MIPI去获取输出时间信息，进而通过自身的逻辑运算得到开启时间信息，并利用管脚输出该开启时间信息，如此，实现缩短闪光灯的开启时间的目的，且由于闪光灯的开启时间是基于曝光时间信息确定出的，所以，能够确保闪光灯的开启时间内目标图像的全部内容均被曝光。
根据本公开的实施例，图6所示的逻辑门电路可以具体为逻辑与电路，即从输出时间信息和曝光时间信息中选取出两者均包含的最短时间段，并从该最短时间段中选取出开启时间信息。
根据本公开的实施例，所述图像采集组件可以集成于处理器中，集成有图像采集组件的处理器可以具体通过类似图6所示的图像采集装置的芯片结构实现。
根据本公开的实施例，利用图像采集装置在对目标对象进行采集时图像的输出时间信息，以及图像的曝光时间信息来确定出控制闪光灯处于工作状态的开启时间信息，这里，由于确定出的开启时间信息是基于输出时间信息以及开启时间信息而确定的，所以，确定出的开启时间信息可以控制处于输出时间信息以及曝光时间信息所对应的时间段内，如此，为缩短闪光灯的开启时间奠定了基础，进而为避免由于闪光灯开启时间较长而导致的亮度不均匀的问题，为提升用户体验奠定了基础。
本公开的实施例是针对摄像头模组的处理芯片的改进，将闪光灯的开启时间限定在属于相邻两帧目标图像之间间隔的第一时间段且属于一帧图像中从第一行结束之前到最后一行开始时候之后的第二时间段。从而相对于相关技术能够减少闪光灯的开启时间从而降低了功耗。同时从而保证闪光灯在短时间内所提供的光亮也是最适合拍照成像的。至少部分解决了现有技术中闪光灯亮着的时间长，温度增加，亮度反而降低的技术问题。
可以理解的是，图像采集组件71和处理器72可以合并在一个模块中实现，或者其中的任意一个模块可以被拆分成多个模块。或者，这些模块中的一个或多个模块的至少部分功能可以与其他模块的至少部分功能相结合，并在一个模块中实现。根据本发明的实施例，图像采集组件71和处理器72中的至少一个可以至少被部分地实现为硬件电路，例如现场可编程门阵列(FPGA)、可编程逻辑阵列(PLA)、片上系统、基板上的系统、封装上的系统、专用集成电路(ASIC)，或可以以对电路进行集成或封装的任何其他的合理方式等硬件或固件来实现，或以软件、硬件以及固件三种实现方式的适当组合来实现。或者，图像采集组件71和处理器72中的至少一个可以至少被部分地实现为计算机程序模块，当该程序被计算机运行时，可以执行相应模块的功能。
