具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
相关技术中，拍摄装置大都只考虑“用户交互”对其功耗模式转换的影响，如一段时间没有“用户交互”，拍摄装置则进入低功耗模式。而在部分场景中，完全依赖于用户而进行功耗控制，不利于拍摄装置的续航，同时，若拍摄装置持续处于低功耗模式甚至关机，再次拍摄时可能需要较长的启动过程，则拍摄装置无法对关键场景进行快速响应，导致错过精彩的瞬间，使得拍摄装置无法得到最佳的用户体验。
以拍摄装置为运动相机为例，运动相机通常在户外使用，以捕捉精彩永恒瞬间。户外使用环境中，由于充电的便利性较差，不仅需要运动相机续航时间尽可能地长，也需要及时拍摄到更多精彩永恒瞬间，故需要在尽可能减少运动相机的功耗消耗的条件下，使得运动相机能够被快速唤醒。
对于此，本发明综合考虑了拍摄装置所拍摄的影像的内容特征和/或拍摄装置的运动状态对拍摄装置的功耗模式的影响，控制拍摄装置处于与内容特征和/或运动状态对应的功耗模式，从而不依赖于用户与拍摄装置的交互操作，也可以实现对拍摄装 置的续航的控制，且在需要拍照或录像等用户操作时，拍摄装置能够对用户操作进行快速响应，使得拍摄装置达到最佳的用户体验。
下面结合附图，对本发明的拍摄装置的控制方法和拍摄装置进行详细说明。在不冲突的情况下，下述的实施例及实施方式中的特征可以相互组合。
图1是本发明一实施例中的拍摄装置的控制方法的方法流程图，如图1所示，所述拍摄装置的控制方法可包括如下步骤：
S101：获取拍摄装置所拍摄的影像的内容特征和/或拍摄装置的运动状态；
在一些实施例中，通过S101获取拍摄装置所拍摄的影像的内容特征。在另一些实施例中，通过S101获取拍摄装置的运动状态。在又一些实施例中，通过S101获取拍摄装置所拍摄的影像的内容特征和拍摄装置的运动状态。
可选的，根据内容特征确定影像是处于静止状态还是处于变化状态，具体的，在特定时间段(如影像的相邻两帧或两帧以上图像对应的时间段)内，当内容特征存在变化时，则确定影像处于变化状态；当内容特征不存在变化时，则确定影像处于静止状态。
可采用不同的方式来判断影像的内容特征是否存在变化，如，可直接对影像进行分析，确定影像的内容特征是否存在变化；可选的，内容特征包括：颜色特征、纹理特征、形状特征、空间关系特征等图像特征信息。在特定时间段内，当上述图像特征信息中任一图像特征信息存在变化时，判断内容特征存在变化，则内容特征指示影像处于变化状态；当上述图像特征信息均不存在变化时，判断内容特征不存在变化，则内容特征指示影像处于静止状态。其中，影像的变化可以从侧面反馈用户当前是否需要进行拍摄，基于此，当影像处于变化状态时，说明用户拍摄的场景发生变化，或者拍摄的特定对象存在移动，则用户仍具有拍摄需求，此时，可以控制拍摄装置处于可拍摄的功耗模式，而当影像处于静止状态时，则说明用户不具有拍摄需求，此时，可以控制拍摄装置处于不需要过多功耗的模式。可以理解，图像特征信息在一定范围内的变化波动可以认为不存在变化。
在某些实施例中，拍摄装置具有具体的拍摄对象(本文称为拍摄装置所拍摄的特定对象)，还可基于特定对象的运动状态，确定影像的内容特征。
可选的，特定对象的运动状态为根据该特定对象的位置信息确定。
作为一种可行的实现方式，可基于外部传感器(如GPS)采集特定对象的位置信息，再根据特定对象的位置信息，判断影像的内容特征是否存在变化。若根据外部传感器的采集信息，确定特定对象的实际位置未发生改变且特定对象的实际位置未发生改变的时长大于或等于第一特定时长(如10秒、20秒或其他时长)，则确定特定对象处于静止状态，由此判断内容特征不存在变化；若根据外部传感器的采集信息，确 定特定对象的实际位置发生改变，则确定特定对象处于移动状态，由此判断内容特征存在变化。
作为另一种可行的实现方式，基于影像分析确定特定对象在影像中连续几帧图像的特征信息，若特定对象在影像中连续几帧图像的特征信息相同，确定特定对象处于静止状态，则确定内容特征指示影像为静止状态；若特定对象在影像中相邻帧图像的特征信息不完全相同，确定特定对象处于移动状态，则确定内容特征指示影像为变化状态。例如，特对对象为动物的特定部位(如眼睛)，若动物的特定部位变化，则可确定动物在影像中相邻帧图像的特征信息不完全相同，从而确定动物处于移动状态。
需要说明的是，本发明实施例中，特定对象可为某一物体的整体，也可为某一物体的特定部分，例如，特定对象可为动物整体，也可为动物的眼睛、耳朵等。
上述实施例中，若根据特定对象的运动状态，确定特定对象处于静止状态，则确定内容特征指示影像为静止状态；若根据特定对象的运动状态，确定特定对象处于移动状态，则确定内容特征指示影像为变化状态。
也可采用不同的方式来获取拍摄装置的运动状态，本实施例中，拍摄装置可包括运动传感器和/或导航系统。可利用运动传感器获取拍摄装置的运动信息和/或利用导航系统获取拍摄装置的位置信息；并根据运动信息和/或拍摄装置的位置信息，确定拍摄装置的运动状态。其中，拍摄装置的运动状态也可以从侧面反馈用户当前是否需要进行拍摄，基于此，当拍摄装置处于移动状态时，说明用户在移动，尤其是用户可能处于运动场景(如滑雪、冲浪、跳伞等)中，则用户仍具有拍摄需求，此时，可以控制拍摄装置处于可拍摄的功耗模式，而当拍摄装置处于非移动状态时，则说明用户不具有拍摄需求，此时，可以控制拍摄装置处于不需要过多功耗的模式。
具体的，若根据运动信息，确定拍摄装置的姿态未变化，和/或根据拍摄装置的位置信息，确定拍摄装置的位置未变化，则确定拍摄装置处于非移动状态；若根据姿态信息，确定拍摄装置的姿态产生变化，和/或根据拍摄装置的位置信息，确定拍摄装置的位置产生变化，则确定拍摄装置处于移动状态。
其中，运动传感器可为陀螺仪，本实施例是利用陀螺仪获取拍摄装置的角速度，在根据拍摄装置的角速度确定拍摄装置的姿态未变化时，确定拍摄装置处于非移动状态；在根据拍摄装置的角速度确定拍摄装置的姿态产生变化时，确定拍摄装置处于移动状态。当然，运动传感器也可为其他能够检测拍摄装置的运动信息的传感器。
导航系统可为GPS，也可为其他定位系统。
本实施例中，当拍摄装置的运动状态为移动状态时，影像的内容特征为变化的；但拍摄装置的运动状态为非移动状态时，内容特征为变化的还是非变化的需要分析影像的图像特征信息进一步确定。
本实施例的拍摄装置可为运动相机，也可为航拍无人机，还可以为其它具有拍摄功能的电子设备，此处不做具体限定。
S102：控制拍摄装置处于与内容特征和/或运动状态对应的功耗模式。
其中，不同的功耗模式对应不同的耗电速度。
本实施例中，功耗模式可包括第一功耗模式或第二功耗模式，第一功耗模式对应的功耗速度大于第二功耗模式对应的功耗速度。其中，第一功耗模式即为拍摄装置处于运行状态的功耗模式，在第一功耗模式下，拍摄装置能够进行拍摄或录像等工作。第二功耗模式可包括：空闲模式、休眠模式或关机模式。当然，第二功耗模式并不限于上述说明的空闲模式、休眠模式和关机模式，还可为其他第二功耗模式。
可选的，拍摄装置包括主控器CPU(Central Processing Unit)、内存DDR(Double Data Rate)和外部电路(如信号放大电路、通信电路等)，其中，主控器CPU与内存DDR、外部电路分别电耦合连接。
需要说明的是，当拍摄装置处于第一功耗模式时，主控器CPU、内存DDR以及外部电路均处于上电运行状态，内存DDR能够与外部交换数据。
当拍摄装置处于空闲模式时，主控器CPU处于上电但未运行状态，此时，主控器CPU能够等待硬件事件，并且，主控器CPU仅维持部分唤醒核心电路上电。在空闲模式下，主控器CPU的耗电速度比拍摄装置处于第一功耗模式下的主控器CPU的耗电速度低。同时，内存DDR处于自刷新状态，内存DDR仅仅用于维持数据不丢失，而不与外部交换数据。在空闲模式下，内存DDR的耗电速度比拍摄装置处于第一功耗模式下的内存DDR的耗电速度低。
当拍摄装置处于休眠模式时，主控器CPU处于掉电状态，即主控器CPU不耗电；内存DDR处于自刷新状态；外部电路非唤醒部分可以掉电。在休眠模式下，拍摄装置的工作状态(即拍摄装置进入第二功耗模式时的工作状态)被保存，一旦出现硬件事件(如按键等)，拍摄装置立刻恢复到保存的工作状态。
当拍摄装置处于关机模式时。主控器CPU、内存DDR以及外部电路都掉电，拍摄装置无功耗消耗。在关机模式下，若要运行拍摄装置，则必须执行完整的启动流程。
拍摄装置在各功耗模式下的耗电速度的排序为：第一功耗模式>空闲模式>休眠模式>关机模式，即空闲模式对应的耗电速度大于休眠模式对应的耗电速度，且休眠模式对应的耗电速度大于关机模式对应的耗电速度。
此外，在上述第二功耗模式下，拍摄装置除了等待唤醒(由任一第二功耗模式切换至第一功耗模式)，不会运行其他软件逻辑，故可以关闭除唤醒所需的部分外其他部分的电源，达到降低功耗的目的。
拍摄装置由不同的第二功耗模式切换至第一功耗模式的时长不同，即在不同的第二功耗模式下，拍摄装置的唤醒速度(时间)不同，本实施例根据影像的内容特征和/或拍摄装置的运动状态来控制拍摄装置的功耗模式，使得拍摄装置在被触发拍照或录像等时，能够进行快速响应，从而尽可能避免拍摄装置错失精彩的拍摄瞬间。可选的，第二功耗模式切换至第一功耗模式的时长与第二功耗模式的耗电速度呈正相关。本实施例中，拍摄装置在各第二功耗模式下的唤醒速度(时间)排序为：空闲模式<休眠模式<关机模式，即拍摄装置由空闲模式切换至第一功耗模式的速度最快(时间最少)，拍摄装置由关机模式切换至第一功耗模式的速度最慢(时间最长)。其中，当拍摄装置处于关机模式时，若拍摄装置再次拍摄，则需要较长的启动过程，拍摄装置无法对关键场景进行快速响应，导致错过精彩的瞬间，从而使得拍摄装置无法得到最佳的用户体验，基于此，在多种第二功耗模式中，关机模式一般可以不启动，而作为最后的备选方案，且可以结合其他预设条件对多种第二功耗模式进行选择，例如，当拍摄装置的电量小于预设电量阈值时，可以进入关机模式。
相关技术中，不同功耗模式之间的切换通过非硬件调整实现，例如，控制影像的显示亮度和/或显示分辨率减小，以减小拍摄装置的功耗，这种方式虽然在一定程度上可以降低功耗消耗，但降低功耗消耗的速度较慢，并不能最大限度地减少不必要的功耗。为了加快降低功耗的速度，以最大限度地减少不必要的功耗，本实施例通过对拍摄装置的硬件的耗电速度进行调整来实现不同功耗模式之间的切换。可选的，在不同的功耗模式下，拍摄装置中的至少一个硬件的耗电速度发生变化，控制所述拍摄装置处于与内容特征/或所述运动状态对应的功耗模式的具体实现过程可包括：对拍摄装置中的至少一个硬件的耗电速度进行调整，以使得拍摄装置切换至与内容特征/或运动状态对应的功耗模式。可以理解，耗电速度的调整，即一时长内耗电量的调整，也即在同一时长下，不同功耗模式的耗电量不同。
例如，将拍摄装置由第一功耗模式切换至空闲模式、休眠模式或关机模式，或者，将拍摄装置由空闲模式切换至休眠模式、关机模式或第一功耗模式，或者，将拍摄装置由休眠模式切换至关机模式或第一功耗模式，或者，将拍摄装置由关机模式切换至第一功耗模式，均可通过调整主控器CPU、内存DDR和外部电路的耗电速度来实现，具体可通过调整相应硬件的工作状态实现，例如，对于主控器CPU而言，可以上电并运行，也可以上电而不运行，还可以下电。
本发明实施例中，综合考虑内容特征和/或运动状态对拍摄装置的功耗模式的影响，以控制拍摄装置处于与内容特征和/或运动状态对应的功耗模式，从而不依赖于用户与拍摄装置的交互操作，也可以实现对拍摄装置的续航的控制，且在需要拍照或录像等用户操作时，拍摄装置能够对用户操作进行快速响应，使得拍摄装置达到最佳的用户体验。
如图2A所示，作为S102的一种实现方式中，在根据内容特征确定影像满足第 一特定策略，和/或根据运动状态确定拍摄装置满足第二特定策略时，控制拍摄装置由第一功耗模式切换至第二功耗模式，在有利于拍摄装置针对用户操作实现快速响应的同时，节省拍摄装置的功耗，提高用户体验。
其中，根据内容特征确定影像满足第一特定策略可包括：根据内容特征确定影像处于静止状态，且影像处于静止状态的时长大于或者等于第一预设时长，如10秒、20秒或其他时长，第一预设时长的大小可根据需要设置。本实施例中，内容特征指示影像为静止状态，且影像处于静止状态的时长较长(大于或等于第一预设时长)时，若继续拍摄或录像，拍摄装置获取的为重复画面，过多的重复画面不仅影响用户体验，也不具有实际使用价值，导致拍摄装置功耗浪费。故本实施例在影像的内容特征长时间未发生改变时，将拍摄装置由第一功耗模式切换至第二功耗模式，从而节省拍摄装置的功耗。可以理解，若内容特征为变化状态，则控制拍摄装置维持在第一功耗模式，从而防止拍摄装置错过精彩的瞬间。当然，也可采用其他策略来判断影像是否满足第一特定策略。
根据运动状态确定拍摄装置满足第二特定策略可包括：根据运动状态确定拍摄装置处于非移动状态，且拍摄装置处于非移动状态的时长大于或者等于第二预设时长，如10秒、20秒或其他时长，第二预设时长的大小可根据需要设置。本实施例中，在拍摄装置的运动状态长时间未移动时，将拍摄装置由第一功耗模式切换至第二功耗模式，从而节省拍摄装置的功耗。可以理解，若运动状态为移动状态，则控制拍摄装置维持在第一功耗模式，防止拍摄装置错过精彩的瞬间。当然，也可采用其他策略来根据运动状态判断拍摄装置是否满足第二特定策略。
如图2B所示，作为S102的一种实现方式中，在根据内容特征确定影像满足第四特定策略，和/或根据运动状态确定拍摄装置满足第五特定策略时，控制拍摄装置由第二功耗模式切换至第一功耗模式，以提升拍摄装置针对诸如用户操作等的快速响应。本实施例中，当拍摄装置处于空闲模式或休眠模式时，可根据内容特征和/或运动状态控制拍摄装置由空闲模式或休眠模式切换至第一功耗模式，通过这样的触发机制，能够避免拍摄装置错过精彩的瞬间。
其中，根据内容特征确定影像满足第四特定策略可包括：确定内容特征为变化状态，且影像处于变化状态的时长大于或者等于第五预设时长，如10秒、20秒或其他时长，第五预设时长的大小可根据需要设置。根据内容特征确影像是否为变化状态的方式可参见步骤S101的相应部分，此处不再赘述。
根据运动状态确定拍摄装置满足第五特定策略可包括：确定运动状态为移动状态，且拍摄装置处于移动状态的时长大于或者等于第六预设时长，如10秒、20秒或其他时长，第六预设时长的大小可根据需要设置。根据运动状态确定拍摄装置是否为移动状态的方式可参见步骤S101的相应部分，此处不再赘述。
其中，第四特定策略或第五特定策略可以具有一定的规则设计，以避免第二功耗模式切换至第一功耗模式的误触发，例如，拍摄装置的运动轨迹可以为预设的运动轨迹。
进一步的，如图3所示的实施例中，所述拍摄装置的控制方法还可包括：
S301：在确定拍摄装置满足第三特定策略时，控制拍摄装置执行与第三特定策略对应的操作。
可选的，确定拍摄装置满足第三特定策略包括：确定拍摄装置距离最近一次获取用户指令的时长大于或等于第三预设时长，即当前时刻至拍摄装置最近一次获取用户指令的时长大于或等于第三预设时长，如10秒、20秒或其他时长，第三预设时长的大小可根据需要设置。也即，在拍摄装置长时间不存在用户交互的情况下，可根据内容特征和/或运动状态来控制拍摄装置的功耗模式，从而达到拍摄装置的响应速度和用户体验的最佳平衡。
本实施例中，用户指令用于指示拍摄装置执行拍摄、录像或其他操作。用户可采用不同的方式与拍摄装置进行交互，例如，在其中一实施例中，拍摄装置包括交互模块，用户指令由交互模块被触发产生。可选的，用户通过操作交互模块使得交互模块产生用户指令。可选的，交互模块基于识别方式确定是否产生用户指令，比如，交互模块在识别到用户的行为为特定行为和/或用户的声音为特定声音信息时，产生用户指令。其中，交互模块可包括：触摸屏、图像传感器、按键和/或按钮，交互模块还可包括：语音模块或其他输入设备。在另一实施例中，拍摄装置可与外部设备通信，用户指令由外部设备发送。其中，外部设备可为控制拍摄装置拍摄的遥控器或控制终端，该控制终端可为手机、Pad等移动终端，也可为其他终端设备。
当然，确定拍摄装置是否满足第三特定策略并不限于上述方式，也可基于其他方式来确定拍摄装置是否满足第三特定策略。
在本实施例中，控制拍摄装置执行与第三特定策略对应的操作包括：控制拍摄装置由第一功耗模式切换至第二功耗模式，即在确定拍摄装置满足第三特定策略时，控制拍摄装置由第一功耗模式切换至第二功耗模式。本实施例中，在确定拍摄装置距离最近一次获取用户指令的时长大于或等于第三预设时长时，控制拍摄装置由第一功耗模式切换至第二功耗模式，通过综合考虑用户交互以及拍摄装置所拍摄的影像的内容特征和/或拍摄装置的运动状态，对拍摄装置的功耗模式进行控制，从而达到拍摄装置的响应速度和用户体验的最佳平衡。
可以理解，第三特定策略对应的操作并不限于上述说明的由第一功耗模式切换至第二功耗模式，也可为其他操作。
进一步的，本实施例的拍摄装置的控制方法还可包括：控制拍摄装置处于第二功耗模式的时长，该步骤是在上述实施例的控制拍摄装置由第一功耗模式切换至第二 功耗模式之后执行的，从而达到拍摄装置的第二功耗模式的运行时长、拍摄装置的响应速度和用户体验的最佳平衡。
本实施例中，第二功耗模式包括多种，如上述列举的空闲模式、休眠模式和关机模式中的至少两种。本实施例的拍摄装置的控制方法还可包括：控制拍摄装置从当前第二功耗模式切换至目标第二功耗模式，达到拍摄装置的响应速度和用户体验的最佳平衡。
可选的，拍摄装置处于当前第二功耗模式时的能耗大于拍摄装置处于目标第二功耗模式时的能耗，从而最大限度地减少拍摄装置的能耗消耗，延长拍摄装置的使用时间。
进一步的，控制拍摄装置从当前第二功耗模式切换至目标第二功耗模式可包括：在确定拍摄装置处于当前第二功耗模式的时长大于或等于第四预设时长时，控制拍摄装置从当前第二功耗模式切换至目标第二功耗模式，以尽可能地减少拍摄装置的能耗消耗。其中，第四预设时长可根据需要设置，如10秒、20秒或其他时长。
图4是本发明一实施例中的拍摄装置的第二功耗模式之间的转换关系示意图。如图4所示实施例中，当当前第二功耗模式为空闲模式时，目标第二功耗模式为休眠模式或关机模式；当当前第二功耗模式为休眠模式时，目标第二功耗模式为关机模式。也即，拍摄装置在关机后，若要运行拍摄装置，则必须执行完整的启动流程。
上述实施例的拍摄装置的控制方法的执行主体可为拍摄装置的控制器，可以理解，控制器可包括一个或多个，单独地或共同地工作。
对应于上述实施例的拍摄装置的控制方法，本发明还提供一种拍摄装置，参见图5，该拍摄装置100可包括图像采集模块110和控制器120，其中，图像采集模块110与控制器120电连接。

控制器120用于：获取图像采集模块110所拍摄的影像的内容特征和/或拍摄装置100的运动状态；并且，控制拍摄装置100处于与内容特征和/或运动状态对应的功耗模式，其中，不同的功耗模式对应不同的耗电速度。
在某些实施例中，参见图6，拍摄装置100还包括交互模块130，诸如，触摸屏、图像传感器、按键、按钮中的至少一种，可以理解，交互模块130还可包括其他输入设备如语音模块。该交互模块130与控制器120电连接，用户指令由交互模块130 产生，并由交互模块130传输至控制器120。
在某些实施例中，参见图7，控制器120与外部设备通信，用户指令通过外部设备发送至控制器120。外部设备可为控制拍摄装置100拍摄的遥控器或控制终端，该控制终端可为手机、Pad等移动终端，也可为其他终端设备。

控制器120的实现过程和工作原理可参见上述实施例的拍摄装置的控制方法的描述，此处不再赘述。
在某些实施例中，控制器120可以是中央处理器(central processing unit，CPU)。控制器120还可以进一步包括硬件芯片。上述硬件芯片可以是专用集成电路(application-specific integrated circuit，ASIC)，可编程逻辑器件(programmable logic device，PLD)或其组合。上述PLD可以是复杂可编程逻辑器件(complex programmable logic device，CPLD)，现场可编程逻辑门阵列(field-programmable gate array，FPGA)，通用阵列逻辑(generic array logic，GAL)或其任意组合。
此外，本发明实施例还提供一种计算机可读存储介质，其上存储有计算机程序，该程序被控制器执行时实现上述实施例的拍摄装置的控制方法的步骤。

以上所揭露的仅为本发明部分实施例而已，当然不能以此来限定本发明之权利范围，因此依本发明权利要求所作的等同变化，仍属本发明所涵盖的范围。
