Description
技术领域
本发明涉及一种白平衡调整系统及方法。
背景技术
目前的自动白平衡调整中，是根据现场光源亮度和光源中红、绿、蓝成分的比重来进行白平衡模式的选择。这种方法存在一定误判的情况。比如，将室外傍晚或阴天等低色温场景误判为室内，从而对照片进行蓝色补偿，造成无法还原真实的室外场景，无法达到预想的效果。

附图说明
图1是本发明实施例提供的一种白平衡调整系统的功能模块图。
图2是本发明实施例提供的一种白平衡调整方法的流程图。
具体实施方式
如图1所示，是本发明实施例提供的一种白平衡调整系统的功能模块图。该白平衡调整系统包括一个处理器11、一个GPS模块12、一个白平衡调整模块13及一个存储器14。
所述处理器11，该处理器11内部预设有一个信号强度阈值，一个第一纬度阈值、一个第二纬度阈值，在本实施例中，为了提高处理速度，采用两个纬度阈值，来划分三个纬度带，即高、中、低三个纬度带。如果需要，可以设置更多个纬度阈值，划分更细的纬度带。在本实施例中，第一纬度阈值是30度，第二纬度阈值是60度。高纬度是指大于60度的纬度，中纬度是指大于等于30度且小于等于60度的纬度，低纬度是指小于30度的纬度。
所述存储器14用于保存一个内建表。该内建表列出高、中、低纬度每段时间对应的白平衡补偿值。
所述处理器11判断GPS模块12是否在可用状态，即是否可以接收到卫星发出的数据。当GPS模块12可以接收到卫星发出的数据时，则GPS模块12处在可用状态，如果GPS模块12不能接收到卫星发出的数据时，则GPS模块12不可用，此时，白平衡调整模块13采用传统白平衡调整，即根据现场光源亮度和光源中红、绿、蓝成分的比重来进行白平衡模式的选择。
当GPS模块12处在可用状态时，处理器11根据从GPS模块12中接收的信号强度与处理器11本身预设的信号强度阈值进行比较，判断当前是在室内还是室外，当信号强度大于所述强度阈值时，则判断当前环境为室外；当信号强度小于等于所述强度阈值时，则判断当前环境为室内。例如，一般在室内的信号强度是小于等于-145dbm(毫瓦分贝)，如果在此范围内，就判断当前环境为室内，而在室外一般是大于-145dbm，在此范围内，则判断当前环境为室外。
当所述处理器11判断出当前处于室外环境时，处理器11根据从GPS模块12中接收的卫星的个数与处理器11本身预设的卫星数目进行比较，判断是否可以成功定位。例如，如果卫星数目不小于四颗，则认为可以成功定位。因为在室外不同纬度，承受可见光的辐射强度不同，而且室外不同时间段，日光强度不同，所以在室外定位成功后，还需要了解室外当时的日照强度。
GPS模块12可以输出当前的经纬度及格林威治时间，所以可以利用GPS模块12判断当前位置的经纬度，处理器11根据当前位置的经度，计算出当前位置与格林威治时间的时差，得到当地时间。处理器11根据当前纬度的高低和当时的时间在存储器14中的内建表中查找与之相对应的室外白平衡调整补偿值，处理器11将白平衡补偿值输出到白平衡调整模块13，进行白平衡调整。例如，在室外白天的情况下，正午时段处于低纬度的非洲，因为室外亮度很高，可能输出抑制亮度的白平衡补偿值，但如果是同时段的处于高纬度的极圈附近，就可以输出提高亮度的白平衡补偿值。
当GPS模块12无法定位时。例如，当拍摄者在峡谷一线天，或是位于高楼林立处，由于有遮蔽，虽然信号很强，但只能接收到数量较少的卫星，不足以定位时，则采用第一室外白平衡模式进行调整，该第一室外白平衡模式调整是白平衡调整模块13内部预设的一种室外白平衡模式调整方式。
如图2所示，是本发明实施例提供的一种白平衡调整方法的流程图。首先，步骤S101，处理器11判断GPS模块12是否在可用状态；
步骤S201，当GPS模块12在不可用状态，利用白平衡调整模块13根据现场光源亮度和光源中红、绿、蓝成分的比重来进行白平衡模式的选择，即采用传统的白平衡调整；
步骤S102，当步骤S101判断出GPS模块12在可用状态时，将GPS模块12输出的信号强度与处理器11内预设的信号强度阈值进行比较，判断是否超过该阈值，本实施例中，所述阈值为-145dbm；
步骤S103，当GPS模块12输出的信号强度超过处理器11内预设的信号强度的阈值时，则认为摄像装置所处环境为室外，根据从GPS模块12中接收的卫星数目是否超过处理器11预设的数目，判断是否可以成功定位，本实施例中，所述阈值为-145dbm，预设的数目为四颗；
步骤S104，当定位成功后，根据GPS模块12输出数据中的纬度与处理器11内预设的纬度阈值进行比较，判断当前所处纬度的高低，且处理器11根据GPS模块12输出数据中的经度及格林威治时间，计算出当地时间，读取存储器14中的内建表，确定当前纬度、当前时间的白平衡补偿值，根据白平衡补偿值进行第二室外白平衡调整，所述第二室外白平衡调整是白平衡调整模块13根据内建表中的白平衡补偿值，直接对摄取的图像进行白平衡调整。本实施例中，所述第一纬度阈值为30度，第二纬度阈值为60度；
步骤S301，当步骤S102中GPS模块12的信号强度小于等于强度的阈值时，则认为摄像装置所处环境为室内，白平衡调整模块13利用室内白平衡模式进行白平衡调整，本实施例中，所述阈值为-145dbm；
步骤S401，当步骤S103中判断无法定位时，白平衡调整模块13进行第一室外白平衡模式调整，该第一室外白平衡模式调整是白平衡调整模块13内部预设的一种室外白平衡模式调整方式。
利用本发明可根据GPS信号强度，其输出的位置参数和时间参数协助数码摄像装置判断拍照所处环境是室内还是室外，进而弥补传统白平衡室内外误判的情形。
另外，本领域技术人员还可在本发明精神内做其它变化，只要不偏离本发明的技术效果，都应包含在本发明所要求保护的范围之内。
