Description

移动终端拍摄系统和移动终端拍摄方法 技术领域
本申请涉及但不限于电子信息技术领域。
背景技术
目前市场上大部分的拍照录像设备，都有一个共同的特征，那就是支持对焦。所谓对焦，就是在取景界面发生变化时，通过不断改变焦距，配合图像处理技术，找到可以使画面清晰的正确焦距。
在上述对焦的过程中，焦距会来回的变化，直到画面达到算法要求的清晰程度。这种焦距的变化会非常直观的表现在预览上，就是预览画面会在不同清晰度下来回抖动直到稳定，以及一定程度的画面形变抖动。这样一个过程，对于静态图像的拍摄来说，由于需要额外等待时间直到对焦完成，因此会导致拍摄的延迟；而对于拍摄动画来说，会严重的影响拍摄的质量。
在正常的拍摄动画过程中，需要不断的变换拍摄场景与对象，为了保证画面拍摄的清晰度，那么到了新的场景中，就需要重新去进行对焦。但是因为录像是持续进行的，所以这个对焦的过程就会被记录到我们最终的动画视频中。这样的一个画面抖动过程，实际上严重破坏了画面的整体的稳定性和流畅性。而且，实际的拍摄过程中，画面是频繁在变化的，也就导致了拍摄时间稍长的动画视频中包涵了大量对焦画面。

基于上述移动终端硬件结构以及电气结构示意图，提出本发明方法以下实施例。
如图3所示，为本发明实施例提供的一种移动终端拍摄系统的结构示意图，本实施例提供的移动终端拍摄系统可以包括：
摄像头310、控制模块320、对焦模块330。在本发明实施例中，摄像头310负责采集图像，同时具有接受命令，调整自身焦距的功能，该摄像头310还负责接收来自控制模块320的命令，调整焦距到要求的位置。
对焦模块330，设置为：对摄像头310对应的拍摄场景进行分析，得到用于对拍摄场景进行拍摄的焦距信息。
在本发明实施例中，对对焦模块330的实现形式不进行限制，本发明实施例中提供以下对焦模块330的实现方案：
1)对焦模块330可以是安装在移动终端中的一个小型摄像头，对焦模块330对焦成功后将信息发送给摄像头310。
2)对焦模块330可以是移动终端内的测距器，对焦模块330通过向拍摄场景发射不可见光并接收场景中反射的不可见光，根据发射与接收不可见光的时间差来确定场景中被摄物与移动终端之间的距离，根据该距离即可确定适于对被摄物拍摄的焦距信息，采用该对焦模块330的移动终端可以如图4所示，为本发明实施例提供的移动终端拍摄系统的一种实现形式的示意图，图4中的对焦模块330例如为设置于移动终端100内的测距器。在本发明实施例中，对焦模块330接受控制模块320的控制，执行对焦动作并将对焦结果反馈给控制模块320，对焦模块330启动后，等待接收到控制模块320的信号后执行对焦。
基于1)和2)中对焦模块330的实现形式，本发明实施例提供的移动终端拍摄系统是应用于单个移动终端的系统。
3)对焦模块330可以是位于摄像头310所在的移动终端外部的外接对焦设备，对焦模块330与移动终端之间通过无线方式进行连接。例如，对焦模块330可以是穿戴设备，该穿戴设备内部例如配置有如2)中的基于测距器的对焦功能。则通过本实施例的技术方案，不需要对移动终端进行结构上的改造，即可实现拍摄中的防抖以及避免延迟，如图5所示，为本发明实施例提供的移动终端拍摄系统的另一种实现形式的示意图，图5中的焦模块330可以为手带式穿戴设备，并与移动终端100建立无线连接。
基于3)中的对焦模块330的实现形式，本发明实施例提供的移动终端拍摄系统是应用于移动终端和外接设备的系统。
4)对焦模块330可以是一台移动终端，对焦模块330与摄像头310所在的移动终端之间无线连接。例如，在两个用户进行拍摄同一场景时，一个用户手持移动终端对焦完成后，可将焦距信息发送给另一用户的移动终端，则另一用户可快速地完成拍摄，且避免了拍摄过程中的画面抖动以及延迟，如图6所示，为本发明实施例提供的移动终端拍摄系统的又一种实现形式的示意图，图6中的焦模块330可以为摄像头310所在的移动终端100之外的另一台移动终端。
基于4)中的对焦模块330的实现形式，本发明实施例提供的移动终端拍摄系统是应用于多台移动终端的系统。
控制模块320，设置为：从对焦模块330获取焦距信息，并将该焦距信息发送给摄像头310。
在本发明实施例中，控制模块320可以是处理器，该控制模块320可以包括在处理器基础上的软硬件。在本发明实施例中，控制模块320，设置为：控制对焦模块330执行对焦，并且接收对焦模块330反馈的焦距信息。同时将相关的焦距信息经过处理，以合适的形式传给摄像头310，使摄像头310调整到正确的对焦位置。
摄像头310，设置为：按控制模块320发送的焦距信息进行调焦，对拍摄场景进行拍摄。
根据本发明实施例的技术方案，要消除拍摄图像时的延迟和抖动，只需要在场景变化后将焦距调整到可以使画面清晰的程度即可，这需要两个条件：1、不要摄像头自己去对焦；2、知道拍摄场景的正确焦距信息，所以在本实施例中利用对焦模块测量拍摄场景的焦距信息，并且将这个焦距信息发送给摄像头，让摄像头完成平滑的对焦过程。
本发明实施例提供的移动终端拍摄系统，在摄像头对拍摄场景进行拍摄之前，通过对焦模块对所述摄像头对应的拍摄场景进行分析，得到适用于当下拍摄场景的焦距信息，并由控制模块从对焦模块获取该焦距信息，将该对 焦信息发送给摄像头，从而摄像头根据该焦距信息对拍摄场景拍摄即可，就能够得到拍摄质量较高的静态图像或动画；本发明实施例提供的技术方案中，通过对焦模块获取的焦距信息以去掉了摄像头进行对焦的过程，使得摄像头拍摄静态图像时不会出现延迟的问题，拍摄动画时不会出现画面抖动的问题。
可选地，参考图3，为本发明实施例提供的另一种移动终端拍摄系统，本实施例提供的移动终端拍摄系统同样可以包括：摄像头310、控制模块320、对焦模块330。
本实施例中的控制模块320，设置为：从摄像头310获取摄像头310的对焦位置，并将该对焦位置发送给对焦模块330。
对焦模块330，设置为：根据控制模块320发送的对焦位置从拍摄场景中选取相应位置，分析用于对拍摄场景中相应位置进行拍摄的焦距信息。
在本发明实施例中，例如摄像头310被设置为中心对焦，那么控制模块320获得这个位置信息后，需要将该位置信息提供给对焦模块330，使对焦模块330也找到相应的位置进行对焦，则得到的焦距信息更加适合摄像头使用。
控制模块320，设置为：从对焦模块330获取焦距信息，并将该焦距信息发送给摄像头310。
摄像头310，设置为：按焦距信息进行调焦，以对拍摄场景进行拍摄。
可选地，在本发明实施例的基础上，还可以提供以下两种用户控制对焦的方案：
第一种对焦方案：控制模块320，还设置为：在接收到用户发出的单次对焦指令时，对对焦模块330发出单次对焦信号；相应地，对焦模块330，还设置为：每接收到控制模块320发送的一次单次对焦信号，对拍摄场景进行一次分析得到焦距信息。
在本发明实施例中，对用户发出单次对焦指令的形式不进行限制，例如，用户可以通过触摸屏幕来触发单次对焦指令。
第二种对焦方案：控制模块320，还设置为：在接收到用户发出的连续对焦指令时，对对焦模块330发出连续对焦信号；相应地，对焦模块330，还设 置为：接收到控制模块320发送的连续对焦信号时，对拍摄场景进行持续分析以连续得到焦距信息。
可选地，在上述多次连续对焦方案的基础上，即在上述第二种对焦方案的基础上，还可以提供用户控制停止对焦的方案：
停止对焦方案：控制模块320，还设置为：在接收到用户发出的停止对焦指令时，对对焦模块330发出停止对焦信号；相应地，对焦模块330，还设置为：接收到控制模块320发送的停止对焦信号时，停止对拍摄场景进行分析得到焦距信息。
在本发明实施例中，对用户发出的上述连续对焦指令和停止对焦指令的形式不进行限制，例如，用户可以通过触摸屏幕来触发连续对焦指令或停止对焦指令；对焦模块330接收到连续对焦信号后，可以按一定的时间间隔来采集焦距信息，也通过其内置的元件来判断已计算的焦距信息是否适于对当前场景进行拍摄：内置的元件可以是微型摄像头，实时按焦距信息采集图像并判断是否清晰，不清晰则再次进行对焦；内置的元件可以是姿态传感器，通过姿态传感器检测到终端姿态改变导致拍摄场景变化时，拍摄场景变化则再次进行对焦。
本发明实施例的技术方案支持两种对焦方式：单次对焦和多次连续对焦。当执行单次对焦命令时，对焦模块330执行一次对焦动作后暂停，并将当次对焦完成状态反馈给控制模块320，其中包括对焦是否成功的信息，如果成功还会返回焦距信息给控制模块320。当接收到连续对焦命令后，对焦模块330会循环执行单次对焦的流程，直到接收到停止的命令。根据对焦模块330的两种工作方式，控制模块320也有两种工作状态。在连续对焦模式下，控制模块320启动对焦模块330连续对焦后，持续接收对焦模块330反馈的信息，如果是成功状态，那么它会把对应的焦距信息设置到摄像头310，循环执行，直到用户选择结束。单次对焦模式下，控制模块320首先会决策是否需要启动对焦，如果需要执行对焦，则启动对焦模块310执行对焦。如果对焦失败，则再次启动对焦，直到对焦成功，返回正确的对焦数据。然后再调整摄像头310焦距。
可选地，如图7所示，为本发明实施例提供的又一种移动终端拍摄系统的 结构示意图。本实施例提供的移动终端拍摄系统可以包括：
摄像头410、控制模块420、对焦模块430、姿态传感器440。
姿态传感器440，设置为：检测移动终端的姿态信息。
在本发明实施例的技术方案中，姿态传感器440可以包括加速度传感器、陀螺仪等等，用于检测移动终端是否发生运动。
控制模块420，设置为：从姿态传感器440获取姿态信息，根据该姿态信息判断移动终端的姿态是否发生变化，并在判断结果为移动终端的姿态发生变化时向对焦模块430发出对焦信号。
可选地，控制模块420设置为根据该姿态信息判断移动终端的姿态是否发生变化，包括：根据该姿态信息判断摄像头410对应的拍摄场景发送变化。在本发明实施例的技术方案中，移动终端的姿态发生变化容易导致摄像头面对的摄像场景发生变化，在摄像场景发生变化时有必要重新计算对于当前摄像场景的焦距信息。根据本实施例的技术方案，只有在场景变化时计算焦距信息，避免过多计算焦距信息造成功耗增加，同时也能够保证在场景变化时保持摄影画面质量较高。
对焦模块430，设置为：每接收到控制模块420发送的一次对焦信号，对拍摄场景进行一次分析得到焦距信息。
控制模块420，设置为：从对焦模块430获取焦距信息，并将该焦距信息发送给摄像头410。
摄像头410，设置为：按控制模块420发送的焦距信息进行调焦，以对拍摄场景进行拍摄。
如图8所示，为本发明实施例提供的一种移动终端拍摄方法的流程图，执行本实施例的方法的移动终端可以包括：摄像头、控制模块、对焦模块。
本实施例提供的方法可以包括以下步骤，即步骤510～步骤530：
步骤510，对焦模块对摄像头对应的拍摄场景进行分析，得到用于对拍摄场景进行拍摄的焦距信息。
在本发明实施例中，摄像头负责采集图像，同时具有接受命令，调整自身焦距的功能，该摄像头还负责接收来自控制模块的命令，调整焦距到要求的位置。在本发明实施例中，对对焦模块的实现形式不进行限制，本发明实施例中提供以下对焦模块的实现方案：
1)对焦模块可以是安装在移动终端中的一个小型摄像头，对焦模块对焦成功后将信息发送给摄像头。
2)对焦模块可以是移动终端内的测距器，对焦模块通过向拍摄场景发射不可见光并接收场景中反射的不可见光，根据发射与接收不可见光的时间差来确定场景中被摄物与移动终端之间的距离，根据该距离即可确定适于对被摄物拍摄的焦距信息，采用该对焦模块的移动终端同样可以如图4所示，图4中的对焦模块330例如为设置于移动终端100内的测距器。在本发明实施例中，对焦模块接受控制模块的控制，执行对焦动作并将对焦结果反馈给控制模块，对焦模块启动后，等待接收控制模块的信号后执行对焦。
基于1)和2)中对焦模块的实现形式，本发明实施例提供的移动终端拍摄系统是应用于单个移动终端的系统。
3)对焦模块可以是位于摄像头所在的移动终端外部的外接设备，对焦模块与移动终端之间通过无线方式进行连接。例如，对焦模块可以是穿戴设备，该穿戴设备内部例如配置有如2)中的基于测距器的对焦功能。则通过本实施例的技术方案，不需要对移动终端进行结构上的改造，即可实现拍摄中的防抖以及避免延迟，同样可以如图5所示，图5中的焦模块330可以为手带式穿戴设备，并与移动终端100建立无线连接。
基于3)中的对焦模块的实现形式，本发明实施例提供的移动终端拍摄系统是应用于移动终端和外接设备的系统。
4)对焦模块可以是一台移动终端，对焦模块与摄像头所在的移动终端之间无线连接。例如，在两个用户进行拍摄同一场景时，一个用户手持移动终端对焦完成后，可将焦距信息发送给另一用户的移动终端，则另一用户可快速地完成拍摄，且避免了拍摄过程中的画面抖动以及延迟，同样可以如图6所示，图6中的焦模块330可以为摄像头310所在的移动终端100之外的另一台移动终端。
基于4)中的对焦模块的实现形式，本发明实施例提供的移动终端拍摄系统是应用于多台移动终端的系统。
步骤520，控制模块从对焦模块获取焦距信息，并将该焦距信息发送给摄像头。
在本发明实施例中，控制模块可以是处理器，控制模块可以包括在处理器基础上的软硬件。在本发明实施例中，控制模块用于控制对焦模块执行对焦，并且接收对焦模块反馈的焦距信息。同时将相关的焦距信息经过处理，以合适的形式传给摄像头，使摄像头调整到正确的对焦位置。
步骤530，摄像头按焦距信息进行调焦，对拍摄场景进行拍摄。
根据本发明实施例的技术方案，要消除拍摄图像时的延迟和抖动，只需要在场景变化后将焦距调整到可以使画面清晰的程度即可，这需要两个条件：1、不要摄像头自己去对焦；2、知道拍摄场景的正确焦距信息，所以在本实施例中利用对焦模块测量拍摄场景的焦距信息，并且将这个焦距信息发送给摄像头，让摄像头完成平滑的对焦过程。
本发明实施例提供的移动终端拍摄方法，在摄像头对拍摄场景进行拍摄之前，通过对焦模块对所述摄像头对应的拍摄场景进行分析，得到适用于当下拍摄场景的焦距信息，并由控制模块从对焦模块获取该焦距信息，将该对焦信息发送给摄像头，从而摄像头根据该焦距信息对拍摄场景拍摄即可，就能够得到拍摄质量较高的静态图像或动画；本发明实施例提供的技术方案中，通过对焦模块获取的焦距信息以去掉了摄像头进行对焦的过程，使得摄像头拍摄静态图像时不会出现延迟的问题，拍摄动画时不会出现画面抖动的问题。
可选地，如图9所示，为本发明实施例提供的另一种移动终端拍摄方法的流程图，本实施例中的移动终端可以包括：摄像头、控制模块、对焦模块。本实施例提供的移动终端拍摄方法可以包括如下步骤，即步骤610～步骤640：
步骤610，控制模块从摄像头获取摄像头的对焦位置，并将该对焦位置发送给对焦模块。
步骤620，对焦模块根据对焦位置从拍摄场景中选取相应位置，分析用于 对拍摄场景中相应位置进行拍摄的焦距信息。
在本发明实施例中，例如摄像头被设置为中心对焦，那么控制模块获得这个位置信息后，需要将该位置信息提供给对焦模块，使对焦模块也找到相应的位置进行对焦，则得到的焦距信息更加适合摄像头使用。
步骤630，控制模块从对焦模块获取焦距信息，并将该焦距信息发送给摄像头。
步骤640，摄像头按焦距信息进行调焦，以对拍摄场景进行拍摄。
可选地，在本发明实施例的基础上，还可以提供以下两种用户控制对焦的方案：
第一种对焦方案，包括如下步骤：控制模块在接收到用户发出的单次对焦指令时，对对焦模块发出单次对焦信号；对焦模块每接收到一次单次对焦信号，对拍摄场景进行一次分析得到焦距信息。
在本发明实施例中，对用户发出单次对焦指令的形式不进行限制，例如，用户可以通过触摸屏幕来触发单次对焦指令。
第二种对焦方案，包括如下步骤：控制模块在接收到用户发出的连续对焦指令时，对对焦模块发出连续对焦信号；对焦模块接收到连续对焦信号时，对拍摄场景进行持续分析以连续得到焦距信息。
可选地，在上述多次连续对焦方案的基础上，即在上述第二种对焦方案的基础上，还可以提供用户控制停止对焦的方案：
停止对焦方案，包括如下步骤：控制模块在接收到用户发出的停止对焦指令时，对对焦模块发出停止对焦信号；对焦模块接收到停止对焦信号时，停止对拍摄场景进行分析得到焦距信息。
在本发明实施例中，对用户发出的上述连续对焦指令和停止对焦指令的形式不进行限制，例如，用户可以通过触摸屏幕来触发连续对焦指令或停止对焦指令；对焦模块接收到连续对焦信号后，可以按一定的时间间隔来采集焦距信息，也通过其内置的元件来判断已计算的焦距信息是否适于对当前场景进行拍摄：内置的元件可以是微型摄像头，实时按焦距信息采集图像并判断是否清晰，不清晰则再次进行对焦；内置的元件可以是姿态传感器，通过 姿态传感器检测到终端姿态改变导致拍摄场景变化时，拍摄场景变化则再次进行对焦。
本发明实施例的技术方案支持两种对焦方式：单次对焦和多次连续对焦。当执行单次对焦命令时，对焦模块执行一次对焦动作后暂停，并将当次对焦完成状态反馈给控制模块，其中包括对焦是否成功的信息，如果成功还会返回焦距信息给控制模块。当接收到连续对焦命令后，对焦模块会循环执行单次对焦的流程，直到接收到停止的命令。根据对焦模块的两种工作方式，控制模块也有两种工作状态。在连续对焦模式下，控制模块启动对焦模块连续对焦后，持续接收对焦模块反馈的信息，如果是成功状态，那么它会把对应的焦距信息设置到摄像头，循环执行，直到用户选择结束。单次对焦模式下，控制模块首先会决策是否需要启动对焦，如果需要执行对焦，则启动对焦模块执行对焦。如果对焦失败，则再次启动对焦，直到对焦成功，返回正确的对焦数据。然后再调整摄像头焦距。
可选地，如图10所示，为本发明实施例提供的又一种移动终端拍摄方法的流程图。本实施例中的移动终端可以包括：摄像头、控制模块、对焦模块、姿态传感器。本实施例提供的移动终端拍摄方法可以包括如下步骤，即步骤710～步骤750：
步骤710，姿态传感器检测移动终端的姿态信息。
在本发明实施例的技术方案中，姿态传感器可以包括加速度传感器、陀螺仪等等，用于检测移动终端是否发生运动。
步骤720，控制模块从姿态传感器获取姿态信息，根据该姿态信息判断移动终端的姿态是否发生变化，并在判断结果为移动终端的姿态发生变化时向对焦模块发出对焦信号。
可选地，步骤720中控制模块根据该姿态信息判断移动终端的姿态是否发生变化，可以理解为：根据该姿态信息判断摄像头应的拍摄场景发送变化。在本发明实施例的技术方案中，移动终端的姿态发生变化容易导致摄像头面对的摄像场景发生变化，在摄像场景发生变化时有必要重新计算对于当前摄 像场景的焦距信息。根据本实施例的技术方案，只有在场景变化时计算焦距信息，避免过多计算焦距信息造成功耗增加，同时也能够保证在场景变化时保持摄影画面质量较高。
步骤730，对焦模块每接收到一次对焦信号，对拍摄场景进行一次分析得到焦距信息。
步骤740，控制模块从对焦模块获取焦距信息，并将该焦距信息发送给摄像头。
步骤750，摄像头按焦距信息进行调焦，以对拍摄场景进行拍摄。
