本发明目的的实现、功能特点及优点将结合实施例，参照附图做进一步说明。
具体实施方式
应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。
本发明的拍摄方法(图像处理方法)，在拍摄照片之前即按下快门之前用户无需进行白平衡调整，而是在拍摄完照片后，用户再在照片上选择色温参考区域来进行白平衡调整，最终获得合乎用户需求的照片效果。
参见图1，提出本发明的拍摄方法一实施例，所述拍摄方法包括以下步骤：
步骤S101：拍摄照片
在拍摄之前，先在拍摄画面上定义至少两个子区域，然后分别以每一子 区域作为色温参考区域进行白平衡调整，然后拍摄出若干照片。每个子区域之间可以有间隔，也可以连续分布，连续分布的情况就相当于将拍摄画面连续分割为多个子区域。
具体拍照过程可以如图2所示，包括以下步骤：
步骤S110：将拍摄画面分成n个子区域S1～Sn，n≥2
取景时，将摄入取景窗口的拍摄画面分割成至少两个子区域，每个子区域的形状和大小不限。优选将拍摄画面平均分割成n个矩形的子区域，n≥2。
步骤S111：分别以子区域S1、S2…Sn为色温参考区域，获得n个色温值
以子区域S1为色温参考区域，计算出子区域S1范围内的平均色温值，并将该色温值作为调整整个拍摄画面的白平衡的依据。依此类推，分别以子区域S2、S3…Sn为色温参考区域，最终共获得n个色温值。
步骤S112：根据n个色温值分别对拍摄画面进行白平衡调整后拍摄获得n张照片
不同的色温值对应的白平衡效果各不相同，从而n个色温值就对应n张不同白平衡效果或色彩效果的照片。本发明一次拍摄，就同时获得若干张不同拍摄效果的照片，且每一张照片都是采用独立白平衡调整拍摄而成。
拍照过程还可以如图3所示，包括以下步骤：
步骤S120：将拍摄画面分成n个子区域S1～Sn，n≥2
取景时，将摄入取景窗口的拍摄画面分割成至少两个子区域，每个子区域的形状和大小不限。优选将拍摄画面平均分割成n个矩形的子区域。
步骤S121：分别以子区域S1、S2…Sn为色温参考区域，获得n个子区域的色温值
以子区域S1为色温参考区域，计算出子区域S1范围内的平均色温值，并将该色温值作为调整整个拍摄画面的白平衡的参考依据。依此类推，分别以子区域S2、S3…Sn为色温参考区域，最终共获得n个色温值。
步骤S122：以整个拍摄画面作为色温参考区域，获得整个拍摄画面的色温值
以整个拍摄画面作为色温参考区域，计算出整个拍摄画面的平均色温值。本步骤S122与步骤S121可以同时进行或分步进行。
步骤S123：计算出每一子区域的色温值与整个拍摄画面的色温值的加权 平均值，获得n个加权平均值
假设子区域S1的色温值为A1，整个拍摄画面的色温值为B，则加权平均值C1＝XA1+YB，其中X、Y为加权系数；并将该加权平均值C1作为调整整个拍摄画面的白平衡的依据。依此类推，分别计算出子区域S2～Sn的色温值与整个拍摄画面的色温值的加权平均值，最终获得C1～Cn共n个加权平均值。
步骤S124：根据n个加权平均值分别对拍摄画面进行白平衡调整后拍摄获得n张照片
不同的色温值对应的白平衡效果各不相同，从而n个加权平均值就对应n张不同白平衡效果或色彩效果的照片。本发明一次拍摄，就同时获得若干张不同拍摄效果的照片，且每一张照片都是采用独立白平衡调整后拍摄而成。
前述拍照过程，也可以以每一子区域为依据逐一调整白平衡后拍摄。即先以子区域S1为色温参考区域进行白平衡调整，并据此拍摄一张照片P1；然后以子区域S2为色温参考区域进行白平衡调整，据此拍摄一张照片P2…依此类推，最终获得P1～Pn共n张照片。
拍摄完照片之后，即进入步骤S102。
步骤S102：在拍摄的照片上显示选择图案
照片拍摄完成后，从拍摄的n张照片中随机调出一张显示于拍摄装置的屏幕上供用户预览，同时在照片上显示一选择图案。选择图案的大小和形状不限，可以呈矩形、圆形、三角形等，优选与前述子区域的大小和形状相同。选择图案的位置、形状和大小可调，用户可在屏幕上拖动选择图案来移动其位置，也可以直接点击屏幕，则选择图案自动移动到用户点击的位置。
步骤S103：根据选择图案的位置确定色温参考区域
当用户将选择图案移动到某一位置时，拍摄装置即确定选择图案所在位置所对应的子区域，并将该子区域作为用户选定的色温参考区域。
在某些实施例中，也可以不在照片上显示选择图案，用户可以直接通过触摸或点击照片来发布操作指令，拍摄装置接收到操作指令后，根据用户触摸或点击照片的位置，确定该位置所对应的子区域，然后将该子区域作为色温参考区域。所述点击包括凌空点击。
步骤S104：显示根据所述色温参考区域进行白平衡调整后拍摄获得的照 片
确定了色温参考区域后，拍摄装置即从拍摄的n张照片中调出以该子区域作为色温参考区域进行白平衡调整后拍摄获得的照片，并在屏幕上显示该照片供用户预览。例如，若所述选择图案所在位置所对应的子区域为S3，拍摄装置则调出以子区域S3为色温参考区域进行白平衡调整而拍摄获得的照片P3，并在屏幕上显示照片P3供用户预览。若用户预览后比较满意，则可以选择保存该照片。照片保存后还可以继续在屏幕上移动选择图案来得到其它不同白平衡效果或色彩效果的照片。
在某些实施例中，选择图案也可以有多个，且各选择图案的位置、形状和大小与前述每一个子区域一一对应，选择图案呈环状环绕于每一子区域的周围。用户点击某一选择图案，则将该选择图案所在位置的子区域作为用户选定的色温参考区域，然后调出并显示以该子区域作为色温参考区域进行白平衡调整后拍摄获得的照片。
在某些实施例中，拍摄装置也可以接收外部设备发送的根据上述拍摄方法拍摄的合成照片，然后在合成照片上显示选择图案，或接收用户发送的对该合成照片的操作指令，据此确定色温参考区域，最后从合成照片中调出根据该色温参考区域进行白平衡调整后拍摄获得的照片并予以显示。
本发明的拍摄方法，在拍照时以拍摄画面的多个区域分别作为色温参考区域进行独立白平衡调整后自动拍摄出具有各种色彩效果或白平衡效果的若干照片，拍照完成后，再供用户选择色温参考区域，根据用户选择的色温参考区域调出之前拍摄的根据该色温参考区域进行白平衡调整后拍摄获得的照片供用户预览选择，使得用户通过一次拍摄就能获得多张满足自己要求的、具有较佳色彩效果的照片。
本发明所提供的先拍照后调整白平衡的解决方案，尤其适用于用户没有足够时间进行白平衡调整或需要快速捕捉画面的特殊拍摄场景，如拍摄快速运动物体的情形。虽然本发明是先拍照后调整白平衡，但实际上已经在拍照时获得了多张进行独立白平衡调整后的照片，因此能够在事后选择色温参考区域后准确还原之前拍摄环境下的白平衡效果，兼具了事前和事后白平衡调整的优势。从而，既满足了用户在不同使用场景下的拍摄需求，又能达到事后独立调整白平衡的效果，且拍摄一次就能获得多张具有独立白平衡效果的 照片，极大的提升了用户体验。
参见图4，提出本发明的拍摄装置(图像处理装置)一实施例，所述拍摄装置可以是相机及具有摄像功能的手机、平板电脑等终端设备。所述拍摄装置为实现上述拍摄方法的拍摄装置，包括拍摄单元、显示单元和处理单元。
拍摄单元110：设置为将景物摄入取景窗口，并将取景窗口中的拍摄画面拍摄为照片。在拍摄照片时，拍摄单元110将拍摄画面分成至少两个子区域，分别以每一子区域作为色温参考区域进行白平衡调整后拍摄出至少两张照片。其中，每个子区域的形状和大小不限，每个子区域之间可以有间隔，也可以连续分布，连续分布的情况就相当于将拍摄画面连续分割为多个子区域。优选将拍摄画面平均分割成n个矩形的子区域S1～Sn，n≥2。
在某些实施例中，拍摄单元110计算出每一子区域的色温值，最终获得至少两色温值；根据所述至少两色温值分别对拍摄画面进行白平衡调整。具体的，拍摄单元110以子区域S1为色温参考区域，计算出子区域S1范围内的平均色温值，并将该色温值作为调整整个拍摄画面的的白平衡的依据。依此类推，分别以子区域S2、S3…Sn为色温参考区域，最终共获得n个色温值。最终根据该n个色温值分别对拍摄画面进行白平衡调整后拍摄获得n张不同色彩效果或白平衡效果的照片。
在另一些实施例中，拍摄单元110计算出每一子区域的色温值，最终获得至少两子区域的色温值；同时以整个拍摄画面作为色温参考区域而获得整个拍摄画面的色温值；计算出每一子区域的色温值与整个拍摄画面的色温值的加权平均值，最终获得至少两加权平均值；根据所述至少两加权平均值分别对所述拍摄画面进行白平衡调整。具体的，拍摄单元110以整个拍摄画面作为色温参考区域，计算出整个拍摄画面的平均色温值。假设子区域S1～Sn的色温值分别为A1～An，整个拍摄画面的色温值为B，则子区域S1与整个拍摄画面的色温值的加权平均值为C1＝XA1+YB，其中X、Y为加权系数；并将该加权平均值C1作为调整整个拍摄画面的白平衡的依据。依此类推，分别计算出子区域S2～Sn的色温值与整个拍摄画面的色温值的加权平均值，最终获得C1～Cn共n个加权平均值。最后根据该n个色温值分别对拍摄画面进行白平衡调整后拍摄获得n张不同色彩效果或白平衡效果的照片。
前述拍照过程，拍摄单元110也可以以每一子区域为依据逐一调整白平 衡后拍摄。即先以子区域S1为色温参考区域进行白平衡调整，并据此拍摄一张照片P1；然后以子区域S2为色温参考区域进行白平衡调整，据此拍摄一张照片P2…依此类推，最终获得P1～Pn共n张照片。
显示单元120：设置为在屏幕上显示拍摄画面和照片，并在拍摄的照片上显示选择图案。选择图案的大小和形状不限，可以呈矩形、圆形、三角形等，优选与前述子区域的大小和形状相同。选择图案的位置、形状和大小可调，用户可在屏幕上拖动选择图案来移动其位置，也可以直接点击屏幕，则选择图案自动移动到用户点击的位置。
处理单元130：设置为根据用户指令移动选择图案的位置，根据选择图案的位置确定色温参考区域，并控制显示单元120显示根据该色温参考区域进行白平衡调整后拍摄获得的照片。具体来说，在拍摄完照片后，处理单元130确定选择图案所在位置所对应的子区域，将该子区域作为色温参考区域，从拍摄的n张照片中调出以该子区域作为色温参考区域进行白平衡调整后拍摄获得的照片，并控制显示单元130显示该照片以供用户预览。若用户预览后比较满意，处理单元130则根据用户发布的保存指令保存该照片。照片保存后，用户还可以继续在屏幕上移动选择图案来得到其它不同色彩效果或白平衡效果的照片。
在某些实施例中，选择图案也可以有多个，且各选择图案的位置、形状和大小与前述每一个子区域一一对应，选择图案呈环状环绕于每一子区域的周围。用户点击某一选择图案，处理单元130则将该选择图案所在位置的子区域作为用户选定的色温参考区域，然后调出并显示以该子区域作为色温参考区域进行白平衡调整后拍摄获得的照片。
在某些实施例中，也可以不在照片上显示选择图案，用户可以直接通过触摸或点击照片来发布操作指令，拍摄装置接收到操作指令后，根据用户触摸或点击照片的位置，确定该位置所对应的子区域，然后将该子区域作为色温参考区域。所述点击包括凌空点击。
在某些实施例中，拍摄装置也可以接收外部设备发送的根据上述拍摄方法拍摄的合成照片，然后在合成照片上显示选择图案，或接收用户发送的对该合成照片的操作指令，据此确定色温参考区域，最后从合成照片中调出根据该色温参考区域进行白平衡调整后拍摄获得的照片并予以显示。
本发明的拍摄装置，在拍照时以拍摄画面的多个区域分别作为色温参考区域进行独立白平衡调整后自动拍摄出具有各种色彩效果或白平衡效果的若干照片，拍照完成后，再供用户选择色温参考区域，根据用户选择的色温参考区域调出之前拍摄的根据该色温参考区域进行白平衡调整后拍摄获得的照片供用户预览选择，使得用户通过一次拍摄就能获得多张满足自己要求的、具有较佳色彩效果的照片。
本发明所提供的先拍照后调整白平衡的拍摄装置，尤其适用于用户没有足够时间进行白平衡调整或需要快速捕捉画面的特殊拍摄场景，如拍摄快速运动物体的情形。虽然本发明是先拍照后调整白平衡，但实际上已经在拍照时获得了多张进行独立白平衡调整后的照片，因此能够在事后选择色温参考区域后准确还原之前拍摄环境下的白平衡效果，兼具了事前和事后白平衡调整的优势。从而，既满足了用户在不同使用场景下的拍摄需求，又能达到事后独立调整白平衡的效果，且拍摄一次就能获得多张具有独立白平衡效果的照片，极大的提升了用户体验。
应当理解的是，以上仅为本发明的优选实施例，不能因此限制本发明的专利范围，凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本发明的专利保护范围内。
