技术领域
本申请实施例涉及通信技术领域,尤其涉及一种拍摄方法、装置及电子设备。
背景技术
随着电子设备拍摄功能的提升,用户使用电子设备拍摄各种各样的照片和视频,已经成为人们记录生活中美好时光的重要途径。
在相关技术中,用户可以使用电子设备的慢动作功能,来捕捉一个快速变化的动作,还可以使用连拍功能,对一个拍摄对象进行连拍。例如,气球爆裂的过程、皮球落地后弹起的过程等。通常情况下,上述功能在用户选择对应的拍摄模式并点击拍摄按钮后,电子设备会直接将摄像头的参数调整为与用户选择的拍摄模式对应的拍摄参数,例如,在用户将拍摄模式切换为慢动作拍摄时,电子设备将摄像头的录像帧率设置为高帧率录像模式,并在用户点击拍摄按钮后,摄像头使用高帧率录像模式进行拍摄。
然而,当用户使用选择的功能进行拍摄时,拍摄对象并不一定始终处于摄像头的拍摄范围内,因此,上述拍摄方式,可能会产生较多的无用帧(没有拍摄对象的图像帧),进而导致拍摄文件占用较大的存储空间,以及摄像头产生较大的功耗。
发明内容
本申请实施例的目的是提供一种拍摄方法、装置及电子设备,能够解决相关技术中,电子设备在拍摄慢动作或连拍时,由于拍摄了较多的无用帧而导致的功耗较大,且生成的拍摄文件占用的存储空间较大的问题。

第五方面,本申请实施例提供了一种芯片,所述芯片包括处理器和通信接口,所述通信接口和所述处理器耦合,所述处理器用于运行程序或指令,实现如第一方面所述的方法。
在本申请实施例中,设置了两个拍摄范围不同的摄像头,当检测到目标拍摄对象进入第一摄像头的拍摄范围内、且未进入第二摄像头的拍摄范围内时,将第二摄像头的录像帧率更新为第一录像帧率(高帧率模式)、或者开启连拍功能,使得目标拍摄对象在进入第二摄像头的拍摄范围之前,第二摄像头处于低帧率录像工作模式,当目标拍摄对象进入第二录像头的拍摄范围内时,第二摄像头能够以高帧率录像模式对目标拍摄对象进行拍摄、或者能够对目标拍摄对象进行连拍,降低了第二摄像头在未对目标拍摄对象进行慢动作拍摄、或者连拍之前的功耗,减少了生成的拍摄文件的文件 大小。

图5是本申请实施例提供的一种电子设备的结构示意图。
具体实施方式
下面将结合本申请实施例中的附图,对本申请实施例中的技术方案进行清楚、完整地描述,显然,所描述的实施例是本申请一部分实施例,而不是全部的实施例。基于本申请中的实施例,本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例,都属于本申请保护的范围。
本申请的说明书和权利要求书中的术语“第一”、“第二”等是用于区别类似的对象,而不用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换,以便本申请的实施例能够以除了在这里图示或描述的那些以外的顺序实施,且“第一”、“第二”等所区分的对象通常为一类,并不限定对象的个数,例如第一对象可以是一个,也可以是多个。此外,说明书以及权利要求中“和/或”表示所连接对象的至少其中之一,字符“/”,一般表示前后关联对象是一种“或”的关系。
本申请实施例提供的拍摄方法可以应用于用户使用电子设备进行拍摄的场景中。
示例性的,针对用户使用电子设备进行拍摄的场景,在相关技术中,电子设备在用户选择对应的拍摄模式并点击拍摄按钮后,电子设备会直接将摄像头的参数调整为与用户选择的拍摄模式对应的拍摄参数。例如,电子设备在拍摄慢动作视频时,通常采用固定的高帧率录像模式进行拍摄,即,电子设备只要开启慢动作视频拍摄功能,摄像头的录像帧率即被设置为高帧率模式。然而,在拍摄对象在未进入拍摄范围内的情况下,摄像头也处于高帧率录像模式的状态,导致摄像头长期处于高功耗模式下,且生成的拍摄文件也较大。
针对这一问题,在相关技术中,对于本领域技术人员来说,比较容易想到通过检测拍摄对象是否处于摄像头的拍摄范围内,来动态调整摄像头的录像帧率,以解决上述问题。然而,通常情况下,由于电子设备在进行慢动作拍摄时,拍摄对象的移动速度较快,若按照上述方法调整摄像头的录像帧率,可能导致拍摄对象已经进入拍摄范围一段时间,或者快要离开拍摄范围时,摄像头的录像帧率才调整为高帧率模式,导致拍摄效果较差。如图1所示,区域11为摄像头的拍摄范围,高速运动的足球在t1时刻并未进入摄像头的拍摄预览范围,此时摄像头可以处于低帧率录像模式下,由于足球的速度很快,电子设备可能在t2时刻才检测到足球已经进入了摄像头的拍摄范围,且将摄像头的录像帧率设置为高帧率,此时,电子设备只在t2时刻之后的时间对足球进行了慢动作拍摄,t2时刻之前的时间只进行了常规拍摄,因此,拍摄效果较差。
因此,本申请实施例提供了一种拍摄方法,能够解决上述可能出现的所有问题。在本申请实施例提供的技术方案中,通过检测两个拍摄范围不同的摄像头采集画面,当未检测到任何拍摄对象进入拍摄范围较大的第一摄像头的拍摄范围内时,拍摄范围较小的第二摄像头处于第二录像帧率的工作模式(低帧率模式)下,当检测到目标拍摄对象进入第一摄像头的拍摄范围内、且未进入第二摄像头的拍摄范围内时,第二摄像头的录像帧率从第二录像帧率更新为第一录像帧率(高帧率模式)、或者开启连拍功能,使得目标拍摄对象在进入第二摄像头的拍摄范围之前,第二摄像头处于低帧率录像工作模式,当目标拍摄对象进入第二录像头的拍摄范围内时,第二摄像头能够以高帧率录像模式对目标拍摄对象进行拍摄、或者能够对目标拍摄对象进行连拍,降低了第二摄像头在未对目标拍摄对象进行慢动作拍摄、或者连拍之前的功耗,减少了生成的拍摄文件的文件大小。
下面结合附图,通过具体的实施例及其应用场景对本申请实施例提供的拍摄方法进行详细地说明。
如图2所示,本申请实施例提供的一种拍摄方法,该方法可以包括下述步骤201和步骤202:
步骤201、当目标拍摄对象进入第一摄像头的拍摄范围内、且未进入第二摄像头的拍摄范围内时,拍摄装置启动第二摄像头的目标拍摄功能。
示例性的,上述第一摄像头可以为具有动态视觉传感器(dynamic vision sensor,DVS)的摄像头,其主要用于检测运动物体;上述第二摄像头为可动态调整录像帧率的摄像头,主要用于拍摄慢动作视频或连拍照片。需要说明的是,动态视觉传感器的工作机理为:基于地址-事件表达的动态视觉传感器模仿生物视觉的工作机理,而传统的视觉图像采集方式以固定频率采集的“帧”为基础,具有高冗余、高延迟、高噪声、低动态范围和高数据量等缺陷,即传统的RGB摄像头需要先采集图像帧,之后再对图像帧进行图像识别,进而判断是否有物体进入摄像头的拍摄范围内,识别速度慢。动态视觉传感器是像素异步工作,仅输出光强发生变化像素的地址和信息,而非被动依次读出“帧”内每个像素信息,从源头上消除冗余数据,具有场景变化实时动态响应、图像超稀疏表示、事件异步输出等特点。因此,相比于RGB摄像头,上述DVS摄像头不仅拍摄范围广,而且响应速度快,可以在物体未进入第二摄像头的拍摄范围之前,识别出进入DVS摄像头的拍摄范围内的物体,进而能够使得电子设备及时开启第二摄像头的高帧率录像模式或者连拍模式。
步骤202、当目标拍摄对象进入所述第二摄像头的拍摄范围内时,拍摄装置获取第二摄像头通过目标拍摄功能采集的目标拍摄对象的图像。
示例性的,电子设备启动对应的拍摄功能后,获取第二摄像头通过该拍摄功能采集的目标拍摄对象的图像。该图像可以为慢动作视频,或者,连拍图片。具体的,当目标拍摄功能为连拍时,电子设备获取第二摄像头针对目标拍摄对象采集的连拍图像;当目标拍摄功能为慢动作拍摄时,电子设备获取第二摄像头针对目标拍摄对象采集的多个慢动作视频帧,并生成慢动作视频。
其中,上述第一摄像头的拍摄范围大于第二摄像头的拍摄范围,且第一摄像头的拍摄范围包括第二摄像头的拍摄范围。上述目标拍摄功能包括:连拍功能,或者,第一录像帧率的录像功能。
示例性的,本申请实施例中,电子设备设置有两个拍摄范围不同的摄像头,且第一摄像头的拍摄范围大于第二摄像头的拍摄范围,运动中的目标拍摄对象首先进入第一摄像头的拍摄范围,并触发第二摄像头相应的功能。之后,目标拍摄对象进入第二摄像头的拍摄范围,使得电子设备有足够的时间,能够调整第二摄像头的工作模式, 避免图1中出现的问题,进而得到拍摄效果较好的拍摄内容。
示例性的,本申请实施例中,电子设备通过设置两个拍摄范围不同的摄像头,当目标拍摄对象进入第一摄像头的拍摄范围内、且未进入第二摄像头的拍摄范围内时,触发电子设备调整第二摄像头的工作模式,具体可以包括以下两种工作模式:
工作模式1:
可选地,在本申请实施例中,工作模式1为高帧率录像模式。
示例性的,当目标拍摄对象未进入第二摄像头的拍摄范围内时,上述第二摄像头的录像帧率为第二录像帧率。即,当目标拍摄对象未进入第一摄像头的拍摄范围内时,第二摄像头处于低帧率录像模式的状态。
示例性的,上述步骤201,可以包括以下步骤201a:
步骤202a、当目标拍摄对象进入第一摄像头的拍摄范围内、且未进入第二摄像头的拍摄范围内时,将第二摄像头的录像帧率从第二录像帧率更新为第一录像帧率;
其中,上述第二录像帧率小于第一录像帧率。
示例性的,当目标拍摄对象进入第一摄像头的拍摄范围内、且未进入第二摄像头的拍摄范围内时,电子设备将第二摄像头的录像帧率从低帧率设置为高帧率。
举例说明,如图3所示,为电子设备的两个摄像头的拍摄范围,其中,摄像头1(即上述第一摄像头)的拍摄范围20大于摄像头2(即上述第二摄像头)的拍摄范围21,足球(即上述目标拍摄对象)在未进入拍摄范围20内时(即T0时刻),摄像头2处于低帧率录像模式的工作状态,当足球进入拍摄范围20、且未进入拍摄范围21时(即T1时刻),电子设备将摄像头2的录像帧率从低帧率更新为高帧率,以使得足球在进入拍摄范围21时(即T2时刻),电子设备能够通过摄像头2对足球进行慢动作拍摄。
如此,电子设备可以在目标拍摄对象进入第一摄像头的拍摄范围内时,将第二摄像头设置为高帧率录像模式,进而使得目标拍摄对象在进入第二摄像头的拍摄范围内时,第二摄像头能够针对目标拍摄对象拍摄过程完整的慢动作视频。
工作模式2:
可选地,在本申请实施例中,工作模式2为连拍模式。
示例性的,当目标拍摄对象未进入第二摄像头的拍摄范围内时,上述第二摄像头的处于未进行拍摄的工作状态,用户只能观察到第二摄像头采集的拍摄预览画面。即,当电子设备将第二摄像头的工作模式调整为连拍模式,并在用户点击拍摄按钮后,第一摄像头处于实时检测状态,第二摄像头处于连拍模式,但未进行拍摄的状态。
示例性的,当目标拍摄对象进入第一摄像头的拍摄范围内、且未进入第二摄像头的拍摄范围内时,电子设备控制第二摄像头进行连续拍摄。
如此,当检测到目标拍摄对象进入第一摄像头的拍摄范围内、且未进入第二摄像头的拍摄范围内时,将第二摄像头的录像帧率更新为第一录像帧率(高帧率模式)、或者开启连拍功能,使得目标拍摄对象在进入第二摄像头的拍摄范围之前,第二摄像头处于低帧率录像工作模式,当目标拍摄对象进入第二录像头的拍摄范围内时,第二摄像头能够以高帧率录像模式对目标拍摄对象进行拍摄、或者能够对目标拍摄对象进行连拍,降低了第二摄像头在未对目标拍摄对象进行慢动作拍摄、或者连拍之前的功耗,减少了生成的拍摄文件的文件大小。
可选地,在本申请实施例中,在第二摄像头拍摄慢动作视频的情况下,为了最大程度降低第二摄像头的功耗,以及拍摄文件的大小,电子设备可以在目标拍摄对象离开摄像头的拍摄范围时,降低第二摄像头的录像帧率。
示例性的,上述步骤202之后,本申请实施例提供的拍摄方法,还可以包括以下步骤202b:
步骤202b、当目标拍摄对象离开第一摄像头或者第二摄像头的拍摄范围时,拍摄装置将第二摄像头的录像帧率从第一录像帧率更新为第二录像帧率。
示例性的,电子设备可以将目标拍摄对象离开第二摄像头的拍摄范围,作为触发将第二摄像头的录像帧率从第一录像帧率更新为第二录像帧率的触发条件,也可以将目标拍摄对象离开第一摄像头的拍摄范围,作为触发将第二摄像头的录像帧率从第一录像帧率更新为第二录像帧率的触发条件。
示例性的,当目标拍摄对象为多个,且多个目标拍摄对象中,仅部分目标拍摄对象离开第一摄像头或者第二摄像头的拍摄范围,电子设备不执行上述操作。当多个目标拍摄对象中的所有拍摄对象离开第一摄像头或者第二摄像头的拍摄范围时,电子设 备将第二摄像头的录像帧率从第一录像帧率更新为第二录像帧率。
需要说明的是,在上述第一摄像头为DVS摄像头的情况下,由于DVS摄像头仅输出光强发生变化像素的地址和信息,而不是被动依次读出“帧”内每个像素信息,因此,对于电子设备来说,仅能获取拍摄对象在DVS摄像头的拍摄范围内的每个时刻的位置坐标点,多个时刻的多个坐标点组成拍摄对象的运动轨迹。因此,对于同一个拍摄对象,其运动轨迹通常为一条符合一定变化规律的曲线,电子设备可以根据该曲线的走势,判断拍摄对象的运动方向,以及该拍摄对象是否离开了DVS摄像头的拍摄范围等信息。对于不同的拍摄对象,当多个不同的拍摄对象都位于DVS摄像头的拍摄范围内时,不同的拍摄对象具有不同的运动曲线。在本申请实施例中,电子设备可以仅通过识别第二摄像头的拍摄范围内是否包括拍摄对象,且无需区分是否为同一拍摄对象,来确定是否调整第二摄像头的参数。
如此,电子设备可以在目标拍摄对象离开摄像头的拍摄范围时,调整摄像头的工作模式,进而最大程度降低第二摄像头的功耗,以及拍摄文件的大小。
进一步可选地,在本申请实施例中,电子设备只检测摄像头拍摄的前景区域中的拍摄对象,而不检测摄像头拍摄的背景区域中的拍摄对象,防止电子设备错误调整第二摄像头的工作模式。
示例性的,上述步骤201之前,本申请实施例提供的拍摄方法,还可以包括以下步骤201a:
步骤201a、拍摄装置检测上述第一摄像头的拍摄预览画面。
其中,上述拍摄预览画面包括:前景区域和背景区域。上述目标拍摄对象为:以超过预设速度进入前景区域中的拍摄对象。该预设速度大于背景区域中任一物体的运动速度。
示例性的,上述前景区域为第二摄像头在当前焦距下,能够清楚拍摄的区域。相对的,背景区域为拍摄预览画面中,除前景区域之外的区域。上述区域为三维空间上的区域。
示例性的,通常情况下,慢动作拍摄的拍摄对象为高速运动的物体,因此,电子设备可以在检测到存在超过预设速度进入前景区域中的物体时,触发电子设备将第二 摄像头的录像帧率从第二录像帧率更新为第一录像帧率。
如此,电子设备可以在进入拍摄范围内的物体满足一定条件时,触发电子设备调整第二摄像头的录像帧率,进而减少误触发的情况发生。
可选地,在本申请实施例中,为了避免用户在使用电子设备进行连拍时,产生较多的空白照片,电子设备在目标拍摄对象离开第一摄像头的拍摄范围后,可以自动关闭第二摄像头的连拍功能。
示例性的,由于第一摄像头具有运动检测功能,因此,可以通过第一摄像头触发电子设备关闭第二摄像头的连拍功能。
示例性的,上述步骤202之后,本申请实施例提供的拍摄方法,还可以包括以下步骤202c:
步骤202c、当目标拍摄对象离开第一摄像头的拍摄范围时,拍摄装置停止第二摄像头的连拍功能。
示例性的,电子设备可以通过第一摄像头实时检测其拍摄范围(包括第二摄像头的拍摄范围)内是否存在运动的物体,以及该物体的运动方向,因此,当电子设备检测到目标拍摄对象离开第一摄像头的拍摄范围时,关闭第二摄像头的连拍功能,防止出现多张空白(没有目标拍摄对象)的图像。
如此,电子设备可以在检测到目标拍摄对象离开第一摄像头的拍摄范围后,关闭第二摄像头的连拍功能,减少空白图像的出现。
本申请实施例提供的拍摄方法,当电子设备未检测到任何拍摄对象进入拍摄范围较大的第一摄像头的拍摄范围内时,拍摄范围较小的第二摄像头处于第二录像帧率的工作模式(低帧率模式)下,当检测到目标拍摄对象进入第一摄像头的拍摄范围内、且未进入第二摄像头的拍摄范围内时,第二摄像头的录像帧率从第二录像帧率更新为第一录像帧率(高帧率模式)、或者开启连拍功能,使得目标拍摄对象在进入第二摄像头的拍摄范围之前,第二摄像头处于低帧率录像工作模式。当目标拍摄对象进入第二录像头的拍摄范围内时,第二摄像头能够以高帧率录像模式对目标拍摄对象进行拍摄、或者能够对目标拍摄对象进行连拍,降低了第二摄像头在未对目标拍摄对象进行慢动作拍摄、或者连拍之前的功耗,减少了生成的拍摄文件的文件大小。
需要说明的是,本申请实施例提供的拍摄方法,执行主体可以为拍摄装置,或者该拍摄装置中的用于执行拍摄方法的控制模块。本申请实施例中以拍摄装置执行拍摄方法为例,说明本申请实施例提供的拍摄装置。
需要说明的是,本申请实施例中,上述各个方法附图所示的。拍摄方法均是以结合本申请实施例中的一个附图为例示例性的说明的。具体实现时,上述各个方法附图所示的拍摄方法还可以结合上述实施例中示意的其它可以结合的任意附图实现,此处不再赘述。

可选地,当目标拍摄对象未进入第一摄像头的拍摄范围内时,第二摄像头的录像帧率为第二录像帧率;处理器110,具体用于当目标拍摄对象进入第一摄像头的拍摄范围内、且未进入第二摄像头的拍摄范围内时,将第二摄像头的录像帧率从第二录像帧率更新为第一录像帧率;其中,第二录像帧率小于第一录像帧率。
如此,电子设备可以在目标拍摄对象进入第一摄像头的拍摄范围内时,将第二摄像头设置为高帧率录像模式,进而使得目标拍摄对象在进入第二摄像头的拍摄范围内 时,第二摄像头能够针对目标拍摄对象拍摄过程完整的慢动作视频。
可选地,处理器110,还用于当目标拍摄对象离开第一摄像头或者第二摄像头的拍摄范围时,将第二摄像头的录像帧率从第一录像帧率更新为第二录像帧率。
如此,电子设备可以在目标拍摄对象离开摄像头的拍摄范围时,调整摄像头的工作模式,进而最大程度降低第二摄像头的功耗,以及拍摄文件的大小。
可选地,处理器110,用于检测第一摄像头的拍摄预览画面;其中,拍摄预览画面包括:前景区域和背景区域;目标拍摄对象为:以超过预设速度进入前景区域中的拍摄对象;预设速度大于背景区域中任一物体的运动速度。
如此,电子设备可以在进入拍摄范围内的物体满足一定条件时,触发电子设备调整第二摄像头的录像帧率,进而减少误触发的情况发生。
可选地,处理器110,还用于当目标拍摄对象离开第一摄像头的拍摄范围时,停止第二摄像头的连拍功能。
如此,电子设备可以在检测到目标拍摄对象离开第一摄像头的拍摄范围后,关闭第二摄像头的连拍功能,减少空白图像的出现。
本申请实施例提供的电子设备,当电子设备未检测到任何拍摄对象进入拍摄范围较大的第一摄像头的拍摄范围内时,拍摄范围较小的第二摄像头处于第二录像帧率的工作模式(低帧率模式)下,当检测到目标拍摄对象进入第一摄像头的拍摄范围内、且未进入第二摄像头的拍摄范围内时,第二摄像头的录像帧率从第二录像帧率更新为第一录像帧率(高帧率模式)、或者开启连拍功能,使得目标拍摄对象在进入第二摄像头的拍摄范围之前,第二摄像头处于低帧率录像工作模式,当目标拍摄对象进入第二录像头的拍摄范围内时,第二摄像头能够以高帧率录像模式对目标拍摄对象进行拍摄、或者能够对目标拍摄对象进行连拍,降低了第二摄像头在未对目标拍摄对象进行慢动作拍摄、或者连拍之前的功耗,减少了生成的拍摄文件的文件大小。
