技术领域
本发明涉及图像处理技术领域，尤其涉及一种相机白平衡快速调整方法、装置及计算机可读存储介质。
背景技术
自动白平衡功能在相机中很常见，主要是和色温相关，目的是使摄影系统能在不同的光照条件下得到准确的色彩还原，也就是在不同的光线条件下，调整好红、绿、蓝三原色的比例，使其混合后成为白色。当白平衡设置不佳的时候，常会出现如下这些情况:在日光灯的房间里拍摄的影像会显得发绿，在室内钨丝灯光下拍摄出来的景物就会偏黄等。而自动白平衡功能，可以在相机拍摄的环境色温变化的时候，主动调整白平衡参数，使得相机图像不因为环境色温变化而出现偏色。
目前的手机摄像头在进入相机功能时，由于摄像头尚未捕捉到当前环境的色彩，此时拍照画面会出现颜色调整的过程，捕捉多帧画面，从画面统计得到当前的色温信息，设置相应的自动白平衡参数。由于需要获取当前的色温信息需要多帧，因此摄像头的白平衡速度变慢，不能及时拍照，会错过许多精彩的瞬间，影响用户体验。

本发明第一实施例提供一种相机白平衡快速调整方法，参照图2，图2为本发明相机白平衡快速调整方法第一实施例的流程示意图，所述相机白平衡快速调整方法包括：
步骤S100，通过色温传感器实时获取移动终端当前环境的色温信息，根据所述色温信息获取对应的白平衡参数；
色温传感器能够在移动终端影像处理过程中精确、稳定的工作，它的作用主要是用于检测终端当前环境的色温，以使摄像画面的色温与环境光水平一致，从而得到稳定的屏幕色温和精确的图像色彩。色温这个概念是摄影领域的一个重要部分，光源总是根据它们的色温来定义，对摄影师而言，光的特性中最重要的是光的强度，其次就是色温了。人类的眼睛能自动调整白平衡，所以一张纸在阳光下看是白色的，在夜晚室内灯光下看也是白色的，但如果我们用同一种类型的胶卷在上述两个环境中拍摄，真实的区别将显示出来，这是区别出售日光下拍摄和钨丝灯光下拍摄胶卷的原因。胶卷的色温响应是固定的，而影像传感器的色温响应是可变的，这是一大优势。色温的单位是开尔文。色彩和开尔文温度的关系起源于黑体辐射体，对它加热直到它发光，在不同温度下呈现的色彩就是色温。当这个黑色物体受热后开始发光时将变成暗红色，如果继续加热就会变成黄色，然后是白色，最后就会变成蓝色。
色温对于数码相机而言就是白平衡的问题。在不同光线的场合下拍摄出的照片会有不同的色温。也就是在各种不同的光线状况下，目标物的色彩会产生变化。在这方面，白色物体变化得最为明显：在室内钨丝灯光下，白色物体看起来会带有橘黄色色调，在这样的光照条件下拍摄出来的景物就会偏黄；但如果是在蔚蓝天空下，则会带有蓝色色调。在这样的光照条件下拍摄出来的景物会偏蓝。对于这些偏差，人眼可以自动进行修正。但是，由于色温传感器本身没有这种功能，因此就有必要对它输出的信号进行一定的修正，这种修正就叫做白平衡。
相机的自动白平衡功能可以自动检测自然光在一天中的色温变化，并根据检测结果自动微调相机白平衡，以适应自然光源的色温改变。在光线充足的户外，使用该功能一般都能得到不错的成像效果，但是在光线色温超出自动控制范围或是某些光线复杂的场合，会影响到自动白平衡调整的准确性，使其还原度不是太高，所拍摄图像的色彩可能出现明显的偏色失真情况。
在相机功能未开启的时候，通过集成在相机镜头附近的色温传感器实时获取当前环境的R/G和B/G信息，通常情况下，色温越高的，B/G越大，也就表示越偏蓝；色温越低的R/G越大，也就表示越偏红。根据获取到的R/G和B/G信息计算出当前环境的色温信息，并将其存储在终端中，以供拍照或摄像的时候立即使用。在当前环境有改变时，将原色温信息替换为当前环境的色温信息并存储新的当前环境色温信息。根据所述色温传感器实时获取的色温信息，设置对应的自动白平衡AWB参数，具体的AWB参数包括R，G，B三个通道的参数，将该AWB参数应用于相机拍摄预览画面，完成相机预览画面的自动白平衡调整。
步骤S200，在启动移动终端的相机功能时，加载所述白平衡参数；
终端在获取到启动相机功能的指令时，显示相机拍照界面，并调取由色温传感器实时获取的色温信息转换而成的白平衡参数。
在本实施例中，终端可以是移动终端，也可以是固定终端，移动终端包括各种摄像设备以及各种设有拍照摄像功能的移动设备，例如智能手机，单反机，摄像机等，固定设备可以是各种设有拍照摄像功能的固定设备，例如台式电脑的摄像头等。
步骤S300，基于所述白平衡参数，调整所述相机的成像效果。
根据所述色温传感器实时获取的色温信息，设置对应的自动白平衡AWB参数，具体的AWB参数包括R，G，B三个通道的参数，将该AWB参数应用于相机拍摄预览画面，完成相机预览画面的自动白平衡调整。
进一步地，在一实施例中，在步骤S30之后，所述方法还包括：
在获取到摄影画面时，将所述白平衡参数应用于照片或者影像画面。
根据色温信息得到的AWB参数不仅应用在相机拍摄的预览画面中，使用户可以肉眼看到当前环境拍出照片的效果，还应用于完成拍摄的照片或者影像的画面中，使用户所得照片或影像与他们在预览画面中看到的一致。
本实施例中提出的相机白平衡快速调整方法，通过色温传感器实时获取移动终端当前环境的色温信息，根据所述色温信息获取对应的白平衡参数；然后在启动移动终端的相机功能时，加载所述白平衡参数；之后基于所述白平衡参数，调整所述相机的成像效果；本发明方法在进入终端的摄像画面前就获取到当前环境的色温信息，有效缩短进入摄像画面之后自动白平衡的调整时间，提高了用户体验，并且能够通过色温传感器采集色温信息，减少了手机的功耗。
基于第一实施例，提出本发明相机白平衡快速调整方法的第二实施例，参照图3，步骤S100之前，所述方法还包括：
步骤S400，校准并存储各个色温值对应的白平衡参数，以使移动终端根据所述色温信息得到对应的白平衡参数。
在相机功能启动前，需要提前对各个色温值对应的白平衡参数进行校准，具体的，获取常用范围内的各个色温值，然后通过校准白平衡获得白平衡AWB参数，也就是R，G，B三个颜色通道的参数值，其中，校准白平衡的过程就是通过调整三个通道的参数值，以使白光呈现标准的白色，也就是让色温传感器检测到的白色中的三原色是相等的。在获取到各个色温值对应的白平衡参数值时，对其进行存储。
根据得到的各个色温值，可以计算出当前环境光线的R/G/B三通道分别地平均值，进而得到R/G参数和B/G参数的范围。
本实施例中提出的相机白平衡快速调整方法，通过校准并存储各个色温值对应的白平衡参数；然后获取各个色温值对应的R/G参数和B/G参数的范围；在启动相机功能之前，获取各个色温对应的自动白平衡参数，以及各个色温对应的R/G参数和B/G参数，可以在相机启动后，立即根据色温信息设置相应的自动白平衡补偿参数，加快了自动白平衡初始化调整的速度，提高了调整效率。
基于第一实施例，提出本发明相机白平衡快速调整方法的第三实施例，参照图4，步骤S100包括：
步骤S110，通过色温传感器实时获取移动终端当前的R/G信息和B/G信息；
在未开启相机功能时，可以通过色温传感器实时获取当前的R/G信息和B/G信息。色温越高的，B/G越大，也就表示越偏蓝；色温越低的R/G越大，也就表示越偏红。
色温传感器能够在移动终端影像处理过程中精确、稳定的工作，它的作用主要是用于检测终端当前环境的色温，以使摄像画面的色温与环境光水平一致，从而得到稳定的屏幕色温和精确的图像色彩。色温这个概念是摄影领域的一个重要部分，光源总是根据它们的色温来定义，对摄影师而言，光的特性中最重要的是光的强度，其次就是色温了。人类的眼睛能自动调整白平衡，所以一张纸在阳光下看是白色的，在夜晚室内灯光下看也是白色的，但如果我们用同一种类型的胶卷在上述两个环境中拍摄，真实的区别将显示出来，这是区别出售日光下拍摄和钨丝灯光下拍摄胶卷的原因。胶卷的色温响应是固定的，而影像传感器的色温响应是可变的，这是一大优势。色温的单位是开尔文。色彩和开尔文温度的关系起源于黑体辐射体，对它加热直到它发光，在不同温度下呈现的色彩就是色温。当这个黑色物体受热后开始发光时将变成暗红色，如果继续加热就会变成黄色，然后是白色，最后就会变成蓝色。
步骤S120，基于所述R/G信息和B/G信息获取对应的色温信息。
根据已有的各个色温值对应的R/G信息和B/G信息的数据，计算出当前R/G信息和B/G信息对应的色温信息，以供相机在开启之后，立即通过该色温信息设置对应的自动白平衡参数。
步骤S130，基于所述色温信息获取对应的白平衡参数。
在相机功能未开启的时候，通过集成在相机镜头附近的色温传感器实时获取当前环境的R/G和B/G信息，通常情况下，色温越高的，B/G越大，也就表示越偏蓝；色温越低的R/G越大，也就表示越偏红。根据获取到的R/G和B/G信息计算出当前环境的色温信息，并将其存储在终端中，以供拍照或摄像的时候立即使用。在当前环境有改变时，将原色温信息替换为当前环境的色温信息并存储新的当前环境色温信息。根据所述色温传感器实时获取的色温信息，设置对应的自动白平衡AWB参数，具体的AWB参数包括R，G，B三个通道的参数，将该AWB参数应用于相机拍摄预览画面，完成相机预览画面的自动白平衡调整。
本实施例中提出的相机白平衡快速调整方法，通过色温传感器实时获取终端当前的R/G信息和B/G信息；然后计算并存储所述R/G信息和B/G信息对应的色温信息；根据已校准并存储在终端的各个色温值与R/G信息和B/G信息的对应关系，通过色温传感器实时获取R/G信息和B/G信息，进而得到色温信息，以供相机进一步得到白平衡参数，为之后的白平衡参数设定提供了基础。
基于第三实施例，提出本发明相机白平衡快速调整方法的第四实施例，参照图5，步骤S110包括：
步骤S111，在当前环境下，通过色温传感器捕捉预设帧数的画面；
相机上的感光芯片CCD有无数的感光单元，这些感光单元上分别覆盖有红、绿、蓝三种滤光片，并且分别承担着感受红、绿、蓝三种原色光的任务。因此，在感光芯片上具有红、绿、蓝三种类型的感光单元，只要景物反射的红、绿、蓝三种色光光能，在感光芯片的三种感光单元上按真实的比例采取，。使得红、绿、蓝三基色混合生成后白色，能得到真实还原的彩色数码图像。主要包括三个颜色通道R，G，B的数值，R代表红色RED，G代表绿色GREEN，B代表蓝色BLUE，这三个颜色也被称作三原色。由于需要获得当前环境的R/G信息和B/G信息，就需要通过捕捉多幅当前环境的画面，然后从画面统计得到当前的色温信息。
步骤S112，基于捕捉到的所述预设帧数画面，统计所述画面对应的R/G信息和B/G信息。
根据实践经验，预设帧数一般是指大约10幅左右的画面数量，基于捕捉到的多幅画面，从画面统计得到对应的R/G信息和B/G信息，其中R，G，B是三个颜色通道的数值，R代表红色RED，G代表绿色GREEN，B代表蓝色BLUE，R/G信息和B/G信息也就是各个颜色通道的取值比例信息。
本实施例中提出的相机白平衡快速调整方法，通过在当前环境下，通过色温传感器捕捉预设帧数的画面；然后基于捕捉到的所述预设帧数画面，统计所述画面对应的R/G信息和B/G信息；能够通过捕捉多帧画面对其进行统计获得R/G信息和B/G信息，以便于之后根据R/G信息和B/G信息得到色温值信息，保证了白平衡调整的效率和准确度。
基于第一实施例，提出本发明相机白平衡快速调整方法的第五实施例，参照图6，步骤S200包括：
步骤S210，在获取到启动相机功能的指令时，根据所述指令开启摄像头；
在获取到启动相机功能的指令时，显示拍摄界面，拍摄界面包括待拍摄画面的预览框，同时开启终端的摄像头，使其可以获取当前镜头所对环境的被摄物体。
步骤S220，在摄像头开启时，加载所述白平衡参数至摄影预览界面。
色温传感器的位置可以由用户自行设定，一般集成在摄像头周围，有的也设置在闪光灯位置，色温传感器可以实时获取当前环境的色温信息。在终端的摄像头启动时，通过色温传感器获取当前环境的色温信息。
色温对于数码相机而言就是白平衡的问题。在不同光线的场合下拍摄出的照片会有不同的色温。也就是在各种不同的光线状况下，目标物的色彩会产生变化。在这方面，白色物体变化得最为明显：在室内钨丝灯光下，白色物体看起来会带有橘黄色色调，在这样的光照条件下拍摄出来的景物就会偏黄；但如果是在蔚蓝天空下，则会带有蓝色色调。在这样的光照条件下拍摄出来的景物会偏蓝。对于这些偏差，人眼可以自动进行修正。但是，由于色温传感器本身没有这种功能，因此就有必要对它输出的信号进行一定的修正，这种修正就叫做白平衡。

本实施例中提出的相机白平衡快速调整方法，通过在获取到启动相机功能的指令时，根据所述指令开启摄像头；然后在摄像头开启时，加载所述白平衡参数至摄影预览界面，以使用户可观测到摄影预览界面经过白平衡参数调整后的效果；本方法在开启摄像头的时候可以立即获得色温信息，而不是在开启摄像头之后通过多次校准，进而获取色温信息，节省了相机在开启时的调整时间，避免一些精彩瞬间流逝过快而来不及捕捉的情况，有效提高了用户体验。
基于第一实施例，提出本发明相机白平衡快速调整方法的第六实施例，参照图7，步骤S300包括：
步骤S310，基于所述白平衡参数，完成对应的白平衡设置；
由于在启动摄像头之前已经存储有各个色温值对应的白平衡参数的数据，因此在摄像头启动时，可以根据色温传感器实时获取的色温信息，获取与该色温信息匹配的白平衡参数。
白平衡参数也叫AWB参数或白平衡补偿参数，是用来合成不同颜色以还原真实色彩的参数，主要包括三个颜色通道R，G，B的数值，R代表红色RED，G代表绿色GREEN，B代表蓝色BLUE，这三个颜色也被称作三原色。当色光的三原色在感光材料上达到平衡时，所拍摄的图像才能获得真实的色彩，即该图像不存在偏色失真。白平衡再直白地说就是不管在任何光源下，都能讲白色物体还原为白色。而三原色在感光材料上达到平衡是指：相机上的感光芯片CCD有无数的感光单元，这些感光单元上分别覆盖有红、绿、蓝三种滤光片，并且分别承担着感受红、绿、蓝三种原色光的任务。因此，在感光芯片上具有红、绿、蓝三种类型的感光单元，只要景物反射的红、绿、蓝三种色光光能，在感光芯片的三种感光单元上按真实的比例采取，就能得到真实还原的彩色数码图像。但是，由于日光和灯光中三原色光之间的比例差异很大，为了补偿日光和灯光在三原色光比例上的差别，可以在数码相机上调整感光芯片中三种感光单元的电频强度，即调整三种感光单元的感光速度ISO，在感光芯片上达到三种感光单元电流强弱的平衡，进而实现数码图像色彩的真实还原。例如，日光中三原色光含量均匀，因此，感光芯片上的三种感光单元的感光速度基本相同；而灯光中蓝光少，红光多，因此，当我们调整白平衡参数或者模式时，感光芯片中的感蓝光单元感光度提高，感红光单元的感光度下降，进而从点流量上扶蓝抑红，达到在感光芯片上的三种感光单元的点流量趋于均衡，最终保证了数码照相机在灯光照明下也能拍出色彩真实的图像。相机终端的白平衡调整，是由影像传感器与模数转换芯片中的物理电频改变来实现的，因此，可以通过调整R，G，B三个颜色通道的值来对感光元件上的各个感光单元的电频强度进行调整，以尽可能的得到最接近真实色彩的图像。
步骤S320，基于所述白平衡设置对当前拍照画面进行自动白平衡预览调整；
在相机功能启动后，终端可以显示拍摄界面，其中，拍摄界面包括待拍摄画面的预览框，也就是当前环境的成像效果。通过获取到的白平衡参数，可以对当前预览画面进行白平衡参数的调整，使其R，G，B三个颜色通道的参数值综合起来可以最大程度的还原当前环境的色彩效果。通过调整感光芯片中三种感光单元的电频强度，即调整三种感光单元的感光速度ISO，在感光芯片上达到三种感光单元电流强弱的平衡，进而实现数码图像色彩的真实还原。
本实施例中提出的相机白平衡快速调整方法，基于所述白平衡参数，完成对应的白平衡设置；然后基于所述白平衡设置对当前拍照画面进行自动白平衡预览调整；对画面的白平衡调整可以更准确的提高成像色彩的还原度，得到更加真实的照片或视频，保证了拍摄质量，有效提高用户体验。
基于上述实施例，提出本发明相机白平衡快速调整方法的第七实施例，参照图8，在本实施例中，在步骤S300之后，该相机白平衡快速调整方法还包括：
步骤S500，在移动终端显示屏上显示所述白平衡参数。
当终端完成对相机的自动白平衡调整时，发出完成信号，终端在接收到完成信号时，显示相机当前的白平衡参数。用户可以在相机拍摄界面触发查看白平衡参数指令，以查看相机当前的白平衡参数。
白平衡参数是用来实现白平衡控制的主要参考数据，白平衡控制就是通过图像调整，使在各种光线条件下拍摄出的照片色彩和人眼所看到的景物色彩完全相同。现在的数码相机都有白平衡感测器，一般位于镜头的四周。数码相机提供的白平衡调节功能，既有自动进行白平衡的，也有手动进行的。即使是自动进行，其修正能力也各不相同。相机的白平衡设置是照相功能中的一个重要的品质参数，由于在成像时白色通常是红绿蓝三色混合而成的，因此白平衡是指数码相机对白色物体的还原，也就是所获得的白色的精确度，其精确度直接决定了拍摄照片的色彩质量，其工作原理为根据环境光源色温的不同，调节感光材料的各个色彩感应强度，使色彩平衡。色温经常受到环境和天气的影响，人造光源和其对应的色温主要包括模拟蓝天日光的色温是6500K、模拟北方平均太阳光的色温：7500K、模拟太阳光的色温是5000K、模拟商店灯光的色温是4000K、钨丝灯的色温是2700K，常见的自然环境对应的色温基本也都在这些范围之内，例如晴天、白天、阴天、傍晚、夜晚等。
步骤S600，根据所述白平衡参数确定当前的拍摄模式。
拍摄模式的具体形式及数量可以由用户自行设定，例如晴天，阴天，白天，夜晚等模式，拍摄模式受光条件的影响，在不同的自然环境中，采用不同的拍摄模式可以保证较好的成像效果。
本实施例中提出的相机白平衡快速调整方法，通过在移动终端显示屏上显示所述白平衡参数；然后根据所述白平衡参数确定当前的拍摄模式；可以使用户得到白平衡调整的反馈信息，提高了用户体验。
