通过上述附图,已示出本公开明确的实施例,后文中将有更详细的描述。这些附图和文字描述并不是为了通过任何方式限制本公开构思的范围,而是通过参考特定实施例为本领域技术人员说明本公开的概念。
具体实施方式
这里将详细地对示例性实施例进行说明,其示例表示在附图中。下面的描述涉及附图时,除非另有表示,不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本公开相一致的所有实施方式。相反,它们仅是与如所附权利要求书中所详述的、本公开的一些方面相一致的装置和方法的例子。
首先对本公开实施例所涉及的几个名词进行解释:
光圈:是一个用来控制光线透过镜头进入机身内感光面的光量的装置,通常位于镜头 内。光圈大小用f值来表示,f数值越大光圈孔径越小,f数值越小光圈孔径越大。光圈f值越小,在同一单位时间内的进光量越多,因为光圈孔径大。
快门:是控制曝光时间长短的一种机械或电子装置,是镜头前阻挡光线进来的装置。
感光度(ISO):是指对光线的感应能力或者说是敏感程度。
图1是根据一示例性实施例示出的一种拍摄参数调整方法的流程图,如图1所示,本实施例涉及的拍摄参数调整方法用于拍摄设备中,该拍摄设备是指具有拍摄功能的设备,比如可以是相机、手机、平板电脑、具有拍摄功能的可穿戴设备,比如智能手环、智能眼镜等。该拍摄参数调整方法包括以下步骤。
在步骤S101中,确定拍摄者瞳孔的大小。
在步骤S102中,根据所述瞳孔的大小调整拍摄参数。
本公开实施例中,确定拍摄者瞳孔的大小可以通过如下的方式实现:
拍摄设备可以以默认参数配置来拍摄获得拍摄者的眼部区域图像,进而通过图像识别技术分割出瞳孔部分的图像即瞳孔图像。在获得拍摄者瞳孔图像之后,需要确定当前拍摄者的瞳孔的大小,可以通过计算瞳孔所占像素点的个数来确定瞳孔的大小。
其中,图像识别技术可以采用相关技术中已经广泛使用的相关技术,本公开中不详细说明。
值得说明的是,上述确定拍摄者瞳孔大小的举例仅是一种举例性说明,实际上还可以通过其他方式来实现,比如通过虹膜识别技术等以及其他生物学手段,不以此为限。
由于拍摄者当前的瞳孔大小反映了当前拍摄环境的光线强弱,因此本公开实施例中,以拍摄者对当前拍摄环境光线强弱的直接反映——瞳孔大小为依据,以实现拍摄设备拍摄参数的自动调整,从而实现最终拍摄出的照片画面的亮暗程度较佳。
之所以以瞳孔大小为调整依据,是因为当周围光线比较暗的情况下,人会不自觉地睁大眼睛以争取尽量看清物体,相反的,在周围光线比较强的情况下,为避免刺眼,人也会微眯双眼,从而人眼瞳孔的大小能够反映当前周围光线的强弱。
拍摄设备的拍摄参数包括但不限于光圈大小、快门速度、感光度(International Organization for Standardization,简称ISO)。这三个对曝光过程具有重要影响的参数的含义以及三者之间的相关关系将在下面详细描述,但值得说明的是,在根据瞳孔大小来调整拍摄参数的过程中,一般来说,首先是调整光圈大小,其次可以根据实际需要进行其他两个参数的进一步调整或者直接根据调整确定的光圈大小自动适配其他两个参数。当然,也可以先调整比如快门速度,进而再调整光圈大小和感光度。以下将以先调整光圈大小进而调整快门速度和感光度为例进行说明。
下面首先介绍上述举例的三个拍摄参数的含义以及三者之间的相互关系:
对于拍照或者摄影来说,曝光正常是基本要求,所谓曝光正常就是既不过曝也不欠曝,合理控制进入到拍摄设备中的光线量。而如何控制进入的光线量,主要涉及光圈大小、快门速度和ISO三种主要参数。那么这三个参数是如果控制进入的光线量的呢,如下介绍。
大光圈更加适合在光线暗的环境中使用,在不改变快门速度的情况下可以获得更多的光线,从而照片得到正常曝光。光圈大小还对景深具有直观的影响,所谓景深简单来说就是背景虚化程度,光圈大,背景虚化能力强,使得拍摄主题更加突出;光圈小,背景虚化能力小,前后景都比较清晰。
快门速度是指快门打开到关闭的时间,快门速度数值小,快门打开着的时间少,进来的光线量就少;快门速度数值大,进来的光线量就多。另外,快门速度值大,更适于拍摄运动物体;快门速度值小,更适于拍摄静止物体。
感光度小的(比如ISO100)画质细腻噪点少;感光度大的(比如ISO6400、ISO12800)画质非常差,噪点很多。
综上所述,三者之间的相互关系总结如下:
在快门速度,ISO不变的情况下,光圈越大,镜头进光量越多,画面越亮,景深越明显。反之光圈越小,画面越暗,景深越弱。
在光圈大小,ISO不变的情况下,快门速度越快,画面越暗,动态虚化表现力越弱。反之快门速度越慢,画面越亮,动态过程表现效果越好。
在快门速度,光圈大小不变的情况下,ISO越高,画面越亮,噪点越多。反之ISO越低,画面越暗,噪点越少。
在介绍了上述三个基本拍摄参数以及三者间的相互关系之后,针对本公开实施例来说,首先是调整以确定光圈大小的设置。
在根据瞳孔大小来调整光圈大小的过程中,可能会涉及到以下几种情况,每种情况的详细实施过程参见后续的实施例一到实施例四的说明。
第一种情况:如果当前拍摄者的瞳孔大小已经为最大或接近最大,那么此时应该将光圈大小调整至比较大,甚至调整至为最大光圈。
第二种情况:如果当前拍摄者的瞳孔大小已经为最小或接近最小,那么此时应该将光圈大小调整至比较小,甚至调整至为最小光圈。
第三种情况:如果拍摄者的瞳孔大小在一定较短时间内是变化的,且向逐渐变大的趋势变化,那么此时应该将光圈大小逐渐增大。可以理解的是,如果拍摄者的瞳孔大小并未达到最大瞳孔大小,那么在逐渐增大光圈大小的过程中,最终的光圈大小应该是低于瞳孔最大时对应的光圈大小的。
第四种情况:如果拍摄者的瞳孔大小在一定较短时间内是变化的,且向逐渐变小的趋势变化,那么此时应该将光圈大小逐渐减小。可以理解的是,如果拍摄者的瞳孔大小并未达到最小瞳孔大小,那么在逐渐减小光圈大小的过程中,最终的光圈大小应该是高于瞳孔最小时对应的光圈大小的。
其中,如图2A所示,图2A中示意性的示出了瞳孔大小的情况。
本公开实施例中,通过确定拍摄者瞳孔的大小,进而根据拍摄者瞳孔的大小来自动调整光圈大小等拍摄参数。由于拍摄者当前的瞳孔大小受当前环境光线强弱的影响,从而以 瞳孔大小为根据,能够实现自动高效地调整拍摄设备的拍摄参数与当前拍摄环境相适应,无需拍摄者具有一定的专业能力,操作简便,实现方便,调整合理。
其中,上述步骤102“根据所述瞳孔的大小调整拍摄参数”可以通过如下的方式实现:
根据预设的所述瞳孔的大小与所述光圈大小的对应关系,调整所述光圈大小。
也就是说,本公开实施例中,在以优先调整光圈大小的上述举例的情况下,可以预先设置瞳孔大小与光圈大小的对应关系,该对应关系的获得可以是预先实验统计获得。当然,在不优先调整光圈大小,比如优先调整快门速度的情况下,也类似相应地预先获得瞳孔大小与快门速度之间的对应关系,以根据该对应关系优先调整快门速度。
图2B示意出了瞳孔大小与光圈大小的对应关系,如2B中,左上示意出的光圈大小为最大,右下示意出的光圈大小为最小,并且,大光圈大小对应了大瞳孔,小光圈对应了小瞳孔,因此,图2B中示意出的光圈大小依次减小的顺序对应了瞳孔大小依次减小的顺序。
针对上述第一种情况,下面将结合一具体的实施例来详细介绍其实施过程,如图3所示。
图3是根据一示例性实施例示出的一种拍摄参数调整方法的实施例一的流程图,如图3所示,上述步骤102的实现方式“根据预设的所述瞳孔的大小与所述光圈大小的对应关系,调整所述光圈大小”,可以包括如下的步骤:
在步骤201中,判断所述瞳孔的大小是否大于或等于第一标准参考值,如果大于或等于第一标准参考值,则执行步骤202。
在步骤202中,调整光圈大小为大于第一预设光圈大小。
人眼瞳孔的尺寸大小一般会有一定的标准参考值可以供参考,上述第一标准参考值,在实际实现时,可以对应瞳孔的最大值,下述第二标准参考值,在实际实现时,可以对应瞳孔的最小值,当然,第一标准参考值也可以根据实际情况设定为一个较大的低于最大值的值,第二标准参考值也可以根据实际情况设定为一个较小的高于最小值的值。其中,第一标准参考值大于第二标准参考值。
对于第一标准参考值或第二标准参考值来说,可能是一个具体的唯一数值,也可能是一个较小的取值区间。本实施例中,不区分该第一标准参考值以及下面提及的第二标准参考值是唯一定值还是取值区间。
对于上述步骤201的判断过程中,如果不大于或不等于第一标准参考值,还可以进行是否小于或等于第二标准参考值的判断,以及在都不满足第一和第二标准参考值时进行瞳孔大小变化趋势的判断。本实施例中仅说明判断瞳孔大小大于或等于第一标准参考值的情况,其他情况将在后续的实施例中分别说明。
如果确定出拍摄者的瞳孔大小大于或等于第一标准参考值,则说明当前周围环境的光线强度比较弱即光线很暗,此时需要配置较大的光圈,即需要将光圈大小调整为较大的光 圈大小。由于光圈大小与光圈值呈相反的趋势,即光圈大,光圈值小;光圈小,光圈值大,因此,需要配置较小的光圈值。
值得说明的是,上述在瞳孔大小大于或等于第一标准参考值时,将光圈大小调整为第一预设光圈大小,该第一预设光圈大小可以是拍摄设备的最大光圈大小,也可以是稍低于最大光圈大小的一种光圈大小配置,可以根据上述光圈大小与瞳孔大小的对应关系设定。
进而,在将拍摄设备的光圈大小调整为一个很大的光圈大小之后,可以根据上述介绍的光圈大小、快门速度和ISO的含义以及三者间的相互关系,适应性调整快门速度和ISO。
举例来说,在调整了光圈大小之后,比如可以优先调整快门速度。由于根据瞳孔大小判断出的当前周围环境光线很暗,则可以将快门速度适当调大些,比如与当前快门速度相比,在通常配置的几种快门速度中,选择高一个或几个级别的快门速度。在光圈大小和快门速度都调整完成之后,拍摄设备可以自动根据当前调整后设定的光圈大小和快门速度自动匹配一个合适的ISO值。
本实施例中,在确定拍摄者的瞳孔大小很大时,以该较大状态的瞳孔大小为依据,将拍摄设备的光圈大小调至一个很大的光圈大小,进而适应性调整快门速度和ISO,能够实现拍摄设备拍摄参数的自动调整,实现方便高效,也与当前拍摄环境相适应,有利于最终拍摄出较佳效果的照片。
针对上述第二种情况,下面将结合一具体的实施例来详细介绍其实施过程,如图4所示。
图4是根据一示例性实施例示出的一种拍摄参数调整方法的实施例二的流程图,如图4所示上述步骤102的实现方式“根据预设的所述瞳孔的大小与所述光圈大小的对应关系,调整所述光圈大小”,可以包括如下的步骤:
在步骤301中,判断所述瞳孔的大小是否小于或等于第二标准参考值,如果小于或等于第二标准参考值,则执行步骤302。
在步骤302中,调整光圈大小为小于第二预设光圈大小。
同样的,本实施例中,不区分该第二标准参考值是唯一定值还是取值区间,而且,该第二预设光圈大小远小于上述的第一预设光圈大小。
如果确定出拍摄者的瞳孔大小小于或等于第二最小标准参考值,则说明当前周围环境的光线强度比较强即光线很亮,此时需要配置较小的光圈,即需要将光圈大小调整为较小的光圈大小。由于光圈大小与光圈值呈相反的趋势,即光圈大,光圈值小;光圈小,光圈值大,因此,需要配置较大的光圈值。
值得说明的是,上述在瞳孔大小小于或等于第二标准参考值时,将光圈大小调整为第二预设光圈大小,该第二预设光圈大小可以是拍摄设备的最小光圈大小,也可以是稍高于最小光圈大小的一种光圈大小配置,可以根据上述光圈大小与瞳孔大小的对应关系设定。
进而,在将拍摄设备的光圈大小调整为一个很小的光圈大小之后,可以根据上述介绍 的光圈大小、快门速度和ISO的含义以及三者间的相互关系,适应性调整快门速度和ISO。
举例来说,在调整了光圈大小之后,比如可以优先调整快门速度。由于根据瞳孔大小判断出的当前周围环境光线很亮,则可以将快门速度适当调小些,比如与当前快门速度相比,在通常配置的几种快门速度中,选择低一个或几个级别的快门速度。在光圈大小和快门速度都调整完成之后,拍摄设备可以自动根据当前调整后设定的光圈大小和快门速度自动匹配一个合适的ISO值。
本实施例中,在确定拍摄者的瞳孔大小为较小时,以该较小状态的瞳孔大小为依据,将拍摄设备的光圈大小调至一个很小的光圈大小,进而适应性调整快门速度和ISO,能够实现拍摄设备拍摄参数的自动调整,实现方便高效,也与当前拍摄环境相适应,有利于最终拍摄出较佳效果的照片。
值得说明的是,上述图3所示的实施例和图4所示的实施例,在实际实施过程中可以合二为一,即步骤201和步骤301的判断步骤可以简单表示是:判断所述瞳孔的大小是否满足标准参考值,如果大于或等于第一标准参考值,则执行步骤202;如果小于或等于第二标准参考值,则执行步骤302。当然,也可以如图4所示中,步骤201和步骤301是分别执行的,当两者的先后执行顺序不以图4所示为限。如果既不满足第一标准参考值的判断,也不满足第二标准参考值的判断,则可以进而进行瞳孔大小变化趋势的判断,可以参考如下图5和图6所示的实施例。
针对上述第三种情况,下面将结合一具体的实施例来详细介绍其实施过程,如图5所示。
图5是根据一示例性实施例示出的一种拍摄参数调整方法的实施例三的流程图,如图5所示,本实施例提供的所述方法可以包括如下的步骤:
在步骤401中,确定拍摄者瞳孔的大小。
在步骤402中,判断先后至少两个时间点时所述拍摄者的瞳孔大小的变化趋势,如果所述变化趋势为变大趋势,则执行步骤403。。
在步骤403中,逐渐增大光圈大小。
值得说明的是,在图3和图4所示的实施例中,因为判断拍摄者当前的瞳孔大小是否大于或等于第一标准参考值,或者判断拍摄者当前的瞳孔大小是否小于或等于第二标准参考值,一幅瞳孔图像即可实现该判断所需,因此,在图3和图4所示的实施例中对瞳孔大小的确定不作具体限定,一次亦可。也就是说,在根据瞳孔图像判断瞳孔大小的情况下,图像的数量不做具体限定,可以是一幅也可以是不止一幅。
但是,在判断出瞳孔大小既不满足上述第一标准参考值的判断,也不满足上述第二标准参考值的判断之后,需要进行瞳孔大小变化趋势的判断,此时则需要确定先后至少两个时间点拍摄者的瞳孔大小,以便进行瞳孔大小变化趋势的判断。
举例来说,在通过获得瞳孔图像来确定瞳孔大小的上述举例中,在只有一幅的瞳孔图 像的情况下,在判断出瞳孔大小既不满足第一标准参考值,也不满足第二标准参考值之后,需要进行瞳孔大小变化趋势的判断,此时还需要再获得至少另外一幅瞳孔图像。而如果之前便已经获得了至少两幅瞳孔图像,则无需再次获得。
进而,对至少两幅图像按时间先后顺序依次确定每一幅瞳孔图像中瞳孔的大小,并根据确定出的各瞳孔的大小判断瞳孔大小变化趋势。
如果瞳孔大小变化趋势为逐渐变大的趋势,说明当前周围环境的光线由强变弱,需要相应逐渐增多进入的光线量,那么需要逐渐增大光圈大小。
但是值得说明的是,在实施过程中,由于拍摄参数的调整是逐渐调整的过程,上述多幅瞳孔图像的也是先后多次拍摄获得的,除第一次拍摄外,之后的每次拍摄获得的瞳孔图像中的瞳孔大小与之前的瞳孔图像中的瞳孔大小相比,会有一定变化。也就是说,本实施例中,瞳孔是逐渐变大的过程,相应的,光圈大小的调整也是逐渐调整的过程,是要与瞳孔大小相适应的,即根据预设获得的瞳孔大小与光圈大小的对应关系来逐渐调整光圈大小。
另外,如果按照时间先后顺序,最后的几幅瞳孔图像中瞳孔大小几乎大小相等时,说明此时周围环境光线强度相对稳定,根据此时的瞳孔大小确定光圈大小最终要调至什么大小。
可以理解的是,如果上述最终的瞳孔大小比第一标准参考值小,那么此时最终的光圈大小低于上述第一预设光圈大小。
进而,在将拍摄设备的光圈大小逐渐调整为一个合适的光圈大小之后,可以根据上述介绍的光圈大小、快门速度和ISO的含义以及三者间的相互关系,适应性地逐渐调整快门速度和ISO。
举例来说,在逐渐调大光圈大小之后,比如可以优先调整快门速度。由于根据瞳孔大小变化趋势判断出的当前周围环境光线由强变弱,则可以将快门速度适当逐渐调小些。每次在光圈大小和快门速度都调整完成之后,拍摄设备可以自动根据当前调整后设定的光圈大小和快门速度自动匹配一个合适的ISO值。
本实施例中,根据拍摄者对当前环境的光线强弱变化所反映的瞳孔大小变化趋势来逐渐调整拍摄设备的光圈大小,进而适应性逐渐调整快门速度和ISO,能够实现拍摄设备拍摄参数的自动调整,实现方便高效,也与当前拍摄环境的变化相适应,有利于最终拍摄出较佳效果的照片。
针对上述第四种情况,下面将结合一具体的实施例来详细介绍其实施过程,如图6所示。
图6是根据一示例性实施例示出的一种拍摄参数调整方法的实施例四的流程图,如图6所示,在图5所示实施例的基础上,本实施例提供的所述方法中,在上述步骤402中判断所述瞳孔大小的变化趋势之后,如果所述变化趋势为变小趋势,则执行本实施例中的如 下步骤404:
在步骤404中,逐渐减小光圈大小。
在图5所示实施例的基础上,仍以上述通过瞳孔图像确定瞳孔大小变化趋势为例,在对至少两幅图像按时间先后顺序依次确定每一幅瞳孔图像中瞳孔的大小,并根据确定出的各瞳孔的大小判断瞳孔大小变化趋势之后,如果变化趋势为逐渐变小的趋势,说明当前周围环境的光线由弱变强,需要相应逐渐减少进入的光线量,那么需要逐渐减小光圈大小。其中,逐渐减小的过程与上述逐渐增大的过程类似,不再重复赘述说明。
可以理解的是,如果上述最终的瞳孔大小比第二标准参考值大,那么此时最终的光圈大小高于上述第二预设光圈大小。
进而,在将拍摄设备的光圈大小逐渐调整为一个合适的光圈大小之后,可以根据上述介绍的光圈大小、快门速度和ISO的含义以及三者间的相互关系,适应性地逐渐调整快门速度和ISO。
举例来说,在逐渐调小光圈大小之后,比如可以优先调整快门速度。由于根据瞳孔大小变化趋势判断出的当前周围环境光线由弱变强,则可以将快门速度适当逐渐调大些。每次在光圈大小和快门速度都调整完成之后,拍摄设备可以自动根据当前调整后设定的光圈大小和快门速度自动匹配一个合适的ISO值。
本实施例中,根据拍摄者对当前环境的光线强弱变化所反映的瞳孔大小变化趋势来逐渐调整拍摄设备的光圈大小,进而适应性逐渐调整快门速度和ISO,能够实现拍摄设备拍摄参数的自动调整,实现方便高效,也与当前拍摄环境的变化相适应,有利于最终拍摄出较佳效果的照片。
上述各实施例中,ISO和快门速度的调整均是根据拍摄者瞳孔大小来调整的,即都是在根据瞳孔大小调整好光圈大小之后,再适应性调整ISO值和快门速度。以下实施例中还提供另外一种调整ISO和快门速度的方式,在上述各实施例调整完拍摄设备的光圈大小之后,可选的,还可以采用如图7所示实施例的方法来进行ISO和快门速度的调整设置。
图7是根据一示例性实施例示出的一种拍摄参数调整方法的实施例五的流程图,如图7所示,该方法包括如下步骤:
在步骤501中,确定被拍摄物的状态,所述状态包括运动状态和静止状态。
对于一张照片来说,其中包含了多种被拍摄的物体,本实施例中所述的被拍摄物是指这多种被拍摄到的物体中的主体,即拍摄者的拍摄目的物。
在确定被拍摄物是运动状态还是静止状态时,一种简单的方式是,由拍摄者根据实际被拍摄物是否运动来触发相应的比如按钮或者选项界面来输入给拍摄设备,但是这种方式具有较大局限性,可以适用于比如相机、手机等拍摄设备中,但是对于较小的可穿戴拍摄设备来说增加了硬件设计复杂度,也给拍摄者操作带来不便。
另外一种简单的方式是,获得被拍摄物图像,根据该被拍摄物图像判断其中包含的被拍摄物的状态。
该种方式的一种简单实现情况是:拍摄一幅包含被拍摄物的图像,通过图像识别技术来识别出图像中的被拍摄物和背景,以该被拍摄物本身所具有的运动属性以及背景特征来确定其运动状态,比如被拍摄物是一只鸟,背景中为广阔蓝图,那么被拍摄物鸟则是处于运动状态的;再比如被拍摄物是一幢建筑,那么其便是处于静止状态的。可见,该种方式也是具有一定局限性的。
该种方式的另一种实现情况是:依时间先后顺序获得至少两幅被拍摄物图像,通过对先后的多幅被拍摄物图像中被拍摄物的运动特征进行分析来确定被拍摄物的状态。
举例来说,以两幅被拍摄物图像为例,可以通过计算两幅被拍摄物图像中被拍摄物的相同像素点间的位移来确定被拍摄物的状态。
在步骤502中,根据所述被拍摄物的状态调整所述快门速度或所述感光度ISO。
在根据被拍摄物的状态调整快门速度和感光度ISO的过程中,可以通过如下方式实现:
如果被拍摄物的状态为运动状态,则加快快门速度;
如果被拍摄物的状态为静止状态,则降低感光度ISO。
根据上述快门速度的含义以及其对于拍摄效果的影响可知,对于拍摄运动状态的物体来说,快门速度相对于ISO来说具有更重要的影响。因此,本实施例中,对于处于运动状态的被拍摄物而言,优先调整快门速度,即将当前的快门速度加快,这样可以捕捉运动瞬间。从而,在光圈大小和快门速度都调整好之后,ISO可以适应性自动调整。
相反的,对于拍摄静止状态的物体来说,ISO相对于快门速度来说具有更重要的影响。因此,本实施例中,对于处于静止状态的被拍摄物而言,优先调整ISO,即将当前的ISO值降低,这样可以降低画面噪点。从而,在光圈大小和ISO都调整好之后,快门速度可以适应性自动调整。
本实施例中,在根据拍摄者瞳孔大小调整好拍摄设备的光圈大小之后,还可以根据被拍摄物处于的运动状态和静止状态来确定优先调整快门速度还是感光度,从而不但能够实现拍摄设备拍摄参数的自动快速高效调整,还能够更好地保证调整后的拍摄参数更加适应于当前的拍摄环境和被拍摄物,有利于保证拍摄效果的优良。
