基于上述移动终端硬件结构、以及相机的电气结构示意图，提出本申请的拍照装置的实施例。
参照图3，图3为本申请的拍照装置的第一实施例的功能模块示意图。
需要强调的是，对本领域技术人员来说，图3所示功能模块图仅仅是一个实施例的示例图，本领域技术人员围绕图3所示的拍照装置的功能模块，可轻易进行新的功能模块的补充；每个功能模块的名称是自定义名称，仅用于辅助理解该拍照装置的每个程序功能块，不用于限定本申请的技术方案，本申请技术方案的核心是，每个自定义名称的功能模块所要达成的功能。
本实施例提出一种拍照装置，所述拍照装置包括：
生成模块10，设置为根据取景框内显示的图像中每个像素点的色度值生成颜色选择界面；
在本实施例中，所述拍照装置包括显示模块，所述显示模块用于在拍照应用的取景框内实时显示图像，可以先开启预设的拍照应用，并通过所述拍照应用的摄像头获取图像，然后所述显示模块在所述拍照应用的取景框内显示获取的所述图像。可以理解的是，在拍照过程中，终端的摄像头可以实时改变，即所述取景框内显示的图像也是可以实时改变的。
在本实施例中，所述生成模块10根据取景框内显示的图像中每个像素点的色度值生成颜色选择界面的实施方式包括：
1)方式一、所述显示模块在所述取景框内显示图像时，先对所述图像进行处理，以得到所述图像的RGB(Red、Green、Blue)颜色模型(也称为加色法混色模型)，在得到所述RGB颜色模型后，先提取所述图像中每个像素点的色度值，所述色度值为三原色值混合得到的值，三原色值包括红色像素值、绿色像素值和蓝色像素值；可以理解的是，每个像素点可以只包括其中一种三原色值，也可以由其中任意两个三原色值相加得到，还可以由三个三原色值相加得到；在得到每个像素点的三原色值后，分别计算每个像素点的三原色值之和，即可得到每个像素点的色度值，例如，像素点的三原色值包括红色像素值、绿色像素值和蓝色像素值，那么所述像素点的色度值的计算公式为：F＝r[R]+g[G]+b[B]，同理，计算出所述图像中每个像素点的色度值；最终，根据所述图像中每个像素点的色度值，将色度值相等的归为同一类，最终可得到所述图像中的每种色度值，根据每种色度值即可确定所述图像中的每种颜色，在得到所述图像中的每种颜色时，进一步计算所述图像中每种色度值占所有色度值的权重值，所述计算方式包括：
a、先分别确定所述图像中每种色度值对应的面积，以及所述图像的总面积，然后将每种色度值对应的面积除以所述图像的总面积，以得到每种色度值占所述图像中所有色度值的比例，最终将计算得到的比例作为每种色度值占所有色度值的权重值；
b、先确定所述图像中每个像素点对应的色度值，然后获取色度值相同的像素点，并分别将色度值相同的多个像素点的数量之和除以所述图像中所有像素点的总数，以得到每种色度值占所述图像中所有色度值的比例，最终将计算得到的比例作为每种色度值占所有色度值的权重值。
在得到每种色度值占所述图像中所有色度值对应的权重值时，所述生成模块10生成颜色选择界面，所述颜色选择界面可以是多种色度值对应的颜色选择界面，也可以是先将多种色度值进行划分，划分为预设种类的色度值，最终显示所述预设种类的色度值对应的颜色选择界面。本实施例中，所述颜色选择界面可以是多种色度值对应的颜色选择界面，可以理解的是，权重值越大的颜色，在所述颜色选择界面中占据的区域越多，权重值越小的颜色，在所述颜色选择界面中占据的区域越少。
2)方式二、可以理解的是，所述图像中的RGB颜色模型中，任何一种颜色都可由R、G、B三原色按不同的比例相加混合而成，当三原色分量都为0(最弱)时混合为黑色光；当三原色分量都为255(最强)时混合为白色光。调整三原色系数r、g、b中的任一系数都会改变颜色的色值，而所述RGB颜色模型的颜色空间采用物理三原色表示，因而物理意义很清楚，适合彩色显像管工作。然而并不适应人的视觉特点，因此，在本实施例中，为了提高拍照过程中图像处理的准确性，参照图4，所述生成模块10包括：
转化子模块11，设置为将所述图像的RGB颜色模型转化为HSV颜色模型，得到转化后的图像；
生成子模块12，设置为根据转化后的图像中每个像素点的色度值生成颜色选择界面。
在本实施例中，在对所述图像进行处理，得到所述图像的RGB颜色模型之后，所述转化子模块11先将所述图像的RGB颜色模型转化为HSV(Hue、Saturation、Value)颜色模型。所述HSV颜色模型可参照图13，所述HSV颜色模型的颜色参数包括：色调H、饱和度S和亮度V。色调H用角度进行度量，取值范围为0°到360°，从红色开始按逆时针方向计算，红色为0°，绿色为120°，蓝色为240°，而它们的补色是：黄色为60°，青色为180°，品红为300°。饱和度S表示颜色接近光谱色的程度。一种颜色，可以看成是某种光谱色与白色混合的结果，其中光谱色所占的比例愈大，颜色接近光谱色的程度就愈高，颜色的饱和度也就愈高。饱和度高，颜色则深而艳。光谱色的白光成分为0，饱和度达到最高。通常取值范围为0％到100％，值越大，颜色越饱和。亮度V表示颜色明亮的程度，对于光源色，亮度值与发 光体的光亮度有关；对于物体色，此值和物体的透射比或反射比有关。通常取值范围为0％(黑)到100％(白)。所述HSV颜色模型相当于圆柱坐标系中的一个圆锥形子集，圆锥的顶面对应于V＝1，它包含RGB模型中的R＝1，G＝1，B＝1三个面，所代表的颜色最亮，色彩H由绕V轴的旋转角得到，饱和度S取值从0到1，同样参照图13，从圆锥顶面的边缘越往圆心靠拢，饱和度的值越小，所以圆锥顶面的半径为1。在所述HSV颜色模型中，在圆锥的顶点处，V＝0，H和S无定义，代表黑色。圆锥的顶面中心即原点处S＝0，V＝1，H无定义，代表白色。从顶点到原点代表亮度渐暗的灰色，即具有不同灰度的灰色。对于这些点，S＝0，H的值无定义。可以说，HSV颜色模型中的V轴对应于RGB颜色空间中的主对角线。在圆锥顶面的边缘上的颜色，V＝1，S＝1，这种颜色是纯色。
在本实施例中，在对所述图像的RGB模型进行转化，转化得到所述HSV颜色模型后，获取转化后的图像中每个像素点的色度值，然后所述生成子模块12根据转化后的所述图像中每个像素点的色度值，以生成多种色度值对应的颜色选择界面。所述根据转化后的所述图像中每个像素点的色度值，以生成多种色度值对应的颜色选择界面的实施方式在下文中详述。
确定模块20，设置为根据所述图像中每个像素点的色度值生成多种色度值对应的颜色选择界面。
在本实施例中，在得到所述图像中多种色度值对应的颜色选择界面后，显示所述颜色选择界面，在所述颜色选择界面中接收到用户基于输入的选择指令时，所述确定模块20确定所述选择指令对应的色度值。可以理解的是，所述颜色选择界面的显示形式包括色度条或色环，所述色环可参照图14，所述色度条或者是所述色环中，包括多种颜色，每种颜色对应一个色度值。
处理模块30，设置为调整所述图像中与所述色度值不匹配的部分对应的显示参数，并在所述取景框内显示调整后的图像，其中，所述显示参数包括透明度或色度值。
在本实施例中，在确定所述选择指令对应的色度值后，所述处理模块30调整所述图像中与所述色度值不匹配的部分对应的显示参数，所述显示参数包括透明度或色度值。所述处理模块30调整的方式例如：将所述图像中与所 述色度值不匹配的部分对应的透明度调高或调低，以使调整的部分与所述图像中未调整的部分明显区分；或者是，调整所述图像中与所述色度值不匹配的部分对应的色度值，可将色度值调整为零，以使调整的部分与所述图像中未调整的部分明显区分。可以理解的是，在所述图像中，调整所述图像中与所述色度值不匹配的部分对应的显示参数，例如调整为黑白图像，而用户选择的色度值对应的部分图像正常显示，使得最终显示的是带有局部彩色的图像。
本实施例中，示例性地，在所述图像中每个像素点的色度值与用户选择的色度值的相似度达到预设比例，如80％时，认为像素点的色度值与用户选择的色度值匹配；或者是，在所述图像中每个像素点的色度值与用户选择的色度值的色度差值小于预设值时，认为像素点的色度值与用户选择的色度值匹配。
本实施例提出的拍照装置，包括生成模块、确定模块和处理模块，所述生成模块根据取景框内显示的图像中每个像素点的色度值生成颜色选择界面，在接收到用户基于所述颜色选择界面输入的选择指令时，所述确定模块确定所述选择指令对应的色度值，所述处理模块调整所述图像中与所述色度值不匹配的部分对应的显示参数，并在所述取景框内显示调整后的图像。如此，实现了在拍照过程中，根据图像中每个像素点的色度值生成颜色选择界面，并在用户选择所述颜色选择界面中的色度值时，调整所述图像中与所述色度值不匹配的部分对应的显示参数，如调整不匹配部分的透明度或是色度值，以使调整的部分与未调整的部分明显区分，使得所述取景框最终显示的图像，仅仅是将用户选择的色度值的部分正常显示，实现了拍照时即可生成局部彩色图像，而不是只能拍摄整体彩色图像或整体黑白图像，本发明实施例提高了拍照的智能性。
进一步地，为了提高拍照的准确性，基于第一实施例提出本申请的拍照装置的第二实施例，在本实施例中，参照图5，所述生成子模块12包括：
获取单元121，设置为获取转化后的所述图像中每个像素点对应的颜色参数，其中，所述颜色参数包括色调、饱和度和亮度；
生成单元122，设置为根据转化后的所述图像中每个像素点对应的颜色 参数，生成每个像素点对应的色度值。
在本实施例中，在得到转化后的图像后，即获取到图像对应的HSV颜色模型后，所述获取单元121获取转化后的所述图像中每个像素点对应的颜色参数，所述颜色参数包括色调H、饱和度S和亮度V；所述生成单元122根据转化后的所述图像中每个像素点对应的颜色参数，生成每个像素点对应的色度值。为更好地理解本实施例，举例如下：在像素点的色调H为240°，饱和度S为0，亮度V为1时，参照图13，可知所述像素点位于所述圆锥体顶面的边缘处，得到所述像素点对应的颜色是蓝色；在像素点的色调H为120°，饱和度S为1，亮度V为1时，参照图13，可知所述像素点位于所述圆锥体顶面的圆心处，得到所述像素点的对应的颜色是白色；在像素点的色调H为120°，饱和度S为0.5，亮度V为1时，参照图13，可知所述像素点位于所述圆锥体顶面的1/2半径处，得到所述像素点对应的颜色是浅绿色。最终，所述生成单元122根据每个像素点对应的颜色参数，可生成每个像素点对应的色度值。
计算单元123，设置为计算转化后的所述图像中每种色度值占所有色度值的权重值。
在本实施例中，在得到每个像素点对应的颜色后，所述计算单元123计算所述图像中每个颜色占所有颜色的权重值，所述计算方式包括：
c、先分别确定转化后的所述图像中每种色度值对应的面积，以及转化后的所述图像的总面积，然后将每种色度值对应的面积除以转化后的所述图像的总面积，以得到每种色度值占转化后的所述图像中所有色度值的比例，最终将计算得到的比例作为每种色度值占所有色度值的权重值；
d、先确定转化后的所述图像中每个像素点对应的色度值，然后获取色度值相同的多个像素点，并分别将色度值相同的多个像素点的数目之和除以转化后的所述图像中的所有像素点的总数，以得到每种色度值占转化后的所述图像中所有色度值的比例，最终将计算得到的比例作为每种色度值占所有色度值的权重值。
所述生成单元122，还设置为根据每种色度值对应的权重值生成所述颜 色选择界面。
在本实施例中，在得到每种色度值占转化后的所述图像中所有色度值对应的权重值时，所述生成单元122生成多种色度值对应的颜色选择界面，其中，权重值越大的颜色，在所述颜色选择界面中占据的区域越多，权重值越小的颜色，在所述颜色选择界面中占据的区域越少。
在RGB颜色模型中，由于RGB图像会损失一部分亮度，比较鲜艳的色彩容易失真，容易导致所述图像生成的颜色选择界面不够准确，因此，在本实施例中，通过计算HSV颜色模型中每个像素点的颜色参数，得到所述图像对应的多种色度值，使得最终生成的颜色种类更加细致，有深色些的颜色，也有浅色些的颜色，对于较鲜艳的颜色也不容易失真，更加真实地反映了图像中包含的多种颜色，提高了拍照过程中，生成颜色选择界面的准确性。
进一步地，为了提高拍照的灵活性，基于第一或第二实施例提出本申请的拍照装置的第三实施例，在本实施例中，参照图6，所述确定模块20包括：
输出单元21，设置为在接收到用户基于所述颜色选择界面输入的选择指令时，输出所述选择指令对应的色度值的容差范围选择界面；
确定单元22，设置为在接收到用户基于所述容差范围选择界面选择的容差范围时，确定所述容差范围对应的色度值，并将确定的所述色度值作为所述选择指令对应的色度值。
在本实施例中，在所述生成模块10根据所述图像中每个像素点的色度值生成多种色度值对应的颜色选择界面后，显示所述颜色选择界面，然后在接收到用户基于所述颜色选择界面输入的选择指令时，所述输出单元21输出所述选择指令对应的色度值的容差范围选择界面。所述容差范围选择界面的显示方式可以包括：a、显示容差范围输入框，以供用户基于所述容差范围输入框输入色度值的容差范围；b、显示曲线界面，如抛物线界面，所述曲线界面中的曲线表示的是每个像素点构成的色度值，在接收到用户调整所述曲线界面中的曲线时，所述确定单元22确定用户调整的范围，将用户调整的范围作为容差范围，并确定所述容差范围对应的色度值。为更好地理解本实施例，举例如下：以HSV颜色模型为例，在用户基于所述颜色选择界面输入的选择 指令对应的色度值为240°，显示所述色度值240°的容差范围输入框，此时，用户在所述容差范围输入框中输入20°，则所述容差范围对应的色度值即为220°到260°，即选择的色度值不仅仅包括蓝色，还可能包括浅蓝色、天蓝色和深蓝色；若用户在所述容差范围输入框中输入40°，则所述容差范围对应的色度值即为200°到280°，即选择的色度值不仅仅包括蓝色，还可能包括群青色、靛青色、浅蓝色、天蓝色和深蓝色等等几种颜色，即容差越大，相当于是以240°蓝色为中心线两边扩散的范围越大，若选择容差范围小，以240°蓝色为中心线两边扩散的范围越小，只会保留跟选择颜色相近的颜色。
在本实施例中，在接收到用户基于所述颜色选择界面输入的选择指令时，输出所述选择指令对应的色度值的容差范围选择界面，然后在接收到用户选择的容差范围时，确定所述容差范围对应的色度值，实现了获取颜色选择界面中的色度值时，不仅仅可以获取用户基于所述颜色选择界面选择的颜色，还可以获取选择的色度值相邻的色度值，使得色度值的获取更加灵活。
进一步地，为了提高拍照的灵活性，基于第一或第二实施例提出本申请的拍照装置的第四实施例，在本实施例中，参照图7，所述拍照装置还包括：

本发明实施例进一步提供一种拍照方法。
参照图8，图8为本申请的拍照方法的实施例的流程示意图。
本实施例提出一种拍照方法，所述拍照方法包括：
步骤S10，根据取景框内显示的图像中每个像素点的色度值生成颜色选择界面。
在本实施例中，所述步骤S10之前，包括在拍照应用的取景框内实时显示图像的步骤，所述在拍照应用的取景框内实时显示图像的方式包括：开启预设的拍照应用，并通过所述拍照应用的摄像头获取图像，然后在所述拍照应用的取景框内显示获取的所述图像。可以理解的是，在拍照过程中，终端的摄像头可以实时改变，即所述取景框内显示的图像也是可以实时改变的。
在本实施例中，所述步骤S10的实施方式包括：
1)方式一、在所述取景框内显示图像时，先对所述图像进行处理，以得到所述图像的RGB(Red、Green、Blue)颜色模型(也称为加色法混色模型)，在得到所述RGB颜色模型后，先提取所述图像中每个像素点的色度值，所述色度值为三原色值混合得到的值，三原色值包括红色像素值、绿色像素值和蓝色像素值；可以理解的是，每个像素点可以只包括其中一种三原色值，也可以由其中任意两个三原色值相加得到，还可以由三个三原色值相加得到；在得到每个像素点的三原色值后，分别计算每个像素点的三原色值之和，即可得到每个像素点的色度值，例如，像素点的三原色值包括红色像素值、绿色像素值和蓝色像素值，那么所述像素点的色度值的计算公式为：F＝r[R]+g[G]+b[B]，同理，计算出所述图像中每个像素点的色度值；最终， 根据所述图像中每个像素点的色度值，将色度值相等的归为同一类，最终可得到所述图像中的每种色度值，根据每种色度值即可确定所述图像中的每种颜色，在得到所述图像中的每种颜色时，进一步计算所述图像中每种色度值占所有色度值的权重值，所述计算方式包括：
a、先分别确定所述图像中每种色度值对应的面积，以及所述图像的总面积，然后将每种色度值对应的面积除以所述图像的总面积，以得到每种色度值占所述图像中所有色度值的比例，最终将计算得到的比例作为每种色度值占所有色度值的权重值；
b、先确定所述图像中每个像素点对应的色度值，然后获取色度值相同的像素点，并分别将色度值相同的多个像素点的数量之和除以所述图像中所有像素点的总数，以得到每种色度值占所述图像中所有色度值的比例，最终将计算得到的比例作为每种色度值占所有色度值的权重值。
在得到每种色度值占所述图像中所有色度值对应的权重值时，生成颜色选择界面，所述颜色选择界面可以是多种色度值对应的颜色选择界面，也可以是先将多种色度值进行划分，划分为预设种类的色度值，最终显示所述预设种类的色度值对应的颜色选择界面。本实施例中，所述颜色选择界面可以是多种色度值对应的颜色选择界面，可以理解的是，权重值越大的颜色，在所述颜色选择界面中占据的区域越多，权重值越小的颜色，在所述颜色选择界面中占据的区域越少。
2)方式二、可以理解的是，所述图像中的RGB颜色模型中，任何一种颜色都可由R、G、B三原色按不同的比例相加混合而成，当三原色分量都为0(最弱)时混合为黑色光；当三原色分量都为255(最强)时混合为白色光。调整三原色系数r、g、b中的任一系数都会改变颜色的色值，而所述RGB颜色模型的颜色空间采用物理三原色表示，因而物理意义很清楚，适合彩色显像管工作。然而并不适应人的视觉特点，因此，在本实施例中，为了提高拍照过程中图像处理的准确性，参照图9，所述步骤S10包括：
步骤S11，将所述图像的RGB颜色模型转化为HSV颜色模型，得到转化后的图像；
步骤S12，根据转化后的图像中每个像素点的色度值生成颜色选择界面。
在本实施例中，在对所述图像进行处理，得到所述图像的RGB颜色模型之后，先将所述图像的RGB颜色模型转化为HSV(Hue、Saturation、Value)颜色模型。所述HSV颜色模型可参照图13，所述HSV颜色模型的颜色参数包括：色调H、饱和度S和亮度V。色调H用角度进行度量，取值范围为0°到360°，从红色开始按逆时针方向计算，红色为0°，绿色为120°，蓝色为240°，而它们的补色是：黄色为60°，青色为180°，品红为300°。饱和度S表示颜色接近光谱色的程度。一种颜色，可以看成是某种光谱色与白色混合的结果，其中光谱色所占的比例愈大，颜色接近光谱色的程度就愈高，颜色的饱和度也就愈高。饱和度高，颜色则深而艳。光谱色的白光成分为0，饱和度达到最高。通常取值范围为0％到100％，值越大，颜色越饱和。亮度V表示颜色明亮的程度，对于光源色，亮度值与发光体的光亮度有关；对于物体色，此值和物体的透射比或反射比有关。通常取值范围为0％(黑)到100％(白)。所述HSV颜色模型相当于圆柱坐标系中的一个圆锥形子集，圆锥的顶面对应于V＝1，它包含RGB模型中的R＝1，G＝1，B＝1三个面，所代表的颜色最亮，色彩H由绕V轴的旋转角得到，饱和度S取值从0到1，同样参照图13，从圆锥顶面的边缘越往圆心靠拢，饱和度的值越小，所以圆锥顶面的半径为1。在所述HSV颜色模型中，在圆锥的顶点处，V＝0，H和S无定义，代表黑色。圆锥的顶面中心即原点处S＝0，V＝1，H无定义，代表白色。从顶点到原点代表亮度渐暗的灰色，即具有不同灰度的灰色。对于这些点，S＝0，H的值无定义。可以说，HSV颜色模型中的V轴对应于RGB颜色空间中的主对角线。在圆锥顶面的边缘上的颜色，V＝1，S＝1，这种颜色是纯色。
在本实施例中，在对所述图像的RGB模型进行转化，转化得到所述HSV颜色模型后，获取转化后的图像中每个像素点的色度值，然后根据转化后的所述图像中每个像素点的色度值，以生成多种色度值对应的颜色选择界面。所述根据转化后的所述图像中每个像素点的色度值，以生成多种色度值对应的颜色选择界面的实施方式在下文中详述。
步骤S20，在接收到用户基于所述颜色选择界面输入的选择指令时，确 定所述选择指令对应的色度值。
在本实施例中，在得到所述图像中多种色度值对应的颜色选择界面后，显示所述颜色选择界面，在所述颜色选择界面中接收到用户基于输入的选择指令时，确定所述选择指令对应的色度值。可以理解的是，所述颜色选择界面的显示形式包括色度条或色环，所述色环可参照图14，所述色度条或者是所述色环中，包括多种颜色，每种颜色对应一个色度值。
步骤S30，调整所述图像中与所述色度值不匹配的部分对应的显示参数，并在所述取景框内显示调整后的图像，其中，所述显示参数包括透明度或色度值。
在本实施例中，在确定所述选择指令对应的色度值后，调整所述图像中与所述色度值不匹配的部分对应的显示参数，所述显示参数包括透明度或色度值。调整的方式例如：将所述图像中与所述色度值不匹配的部分对应的透明度调高或调低，以使调整的部分与所述图像中未调整的部分明显区分；或者是，调整所述图像中与所述色度值不匹配的部分对应的色度值，可将色度值调整为零，以使调整的部分与所述图像中未调整的部分明显区分。可以理解的是，在所述图像中，调整所述图像中与所述色度值不匹配的部分对应的显示参数，例如调整为黑白图像，而用户选择的色度值对应的部分图像正常显示，使得最终显示的是带有局部彩色的图像。
本实施例中，示例性地，在所述图像中每个像素点的色度值与用户选择的色度值的相似度达到预设比例，如80％时，认为像素点的色度值与用户选择的色度值匹配；或者是，在所述图像中每个像素点的色度值与用户选择的色度值的色度差值小于预设值时，认为像素点的色度值与用户选择的色度值匹配。
本实施例提出的拍照方法，根据取景框内显示的图像中每个像素点的色度值生成颜色选择界面，在接收到用户基于所述颜色选择界面输入的选择指令时，确定所述选择指令对应的色度值，最后调整所述图像中与所述色度值不匹配的部分对应的显示参数，并在所述取景框内显示调整后的图像。如此，实现了在拍照过程中，根据图像中每个像素点的色度值生成颜色选择界面，并在用户选择所述颜色选择界面中的色度值时，调整所述图像中与所述色度 值不匹配的部分对应的显示参数，如调整不匹配部分的透明度或是色度值，以使调整的部分与未调整的部分明显区分，使得所述取景框最终显示的图像，仅仅是将用户选择的色度值的部分正常显示，实现了拍照时即可生成局部彩色图像，而不是只能拍摄整体彩色图像或整体黑白图像，本发明实施例提高了拍照的智能性。
进一步地，为了提高拍照的准确性，基于第一实施例提出本申请的拍照方法的第二实施例，在本实施例中，参照图10，所述步骤S12包括：
步骤S121，获取转化后的所述图像中每个像素点对应的颜色参数，其中，所述颜色参数包括色调、饱和度和亮度；
步骤S122，根据转化后的所述图像中每个像素点对应的颜色参数，生成每个像素点对应的色度值。
在本实施例中，在得到转化后的图像后，即获取到图像对应的HSV颜色模型后，获取转化后的所述图像中每个像素点对应的颜色参数，所述颜色参数包括色调H、饱和度S和亮度V；根据转化后的所述图像中每个像素点对应的颜色参数，生成每个像素点对应的色度值。为更好地理解本实施例，举例如下：在像素点的色调H为240°，饱和度S为0，亮度V为1时，参照图13，可知所述像素点位于所述圆锥体顶面的边缘处，得到所述像素点对应的颜色是蓝色；在像素点的色调H为120°，饱和度S为1，亮度V为1时，参照图13，可知所述像素点位于所述圆锥体顶面的圆心处，得到所述像素点对应的颜色是白色；在像素点的色调H为120°，饱和度S为0.5，亮度V为1时，参照图13，可知所述像素点位于所述圆锥体顶面的1/2半径处，得到所述像素点对应的颜色是浅绿色。最终，根据每个像素点对应的颜色参数，可生成每个像素点对应的色度值。
步骤S123，计算转化后的所述图像中每种色度值占所有色度值的权重值。
在本实施例中，在得到每个像素点对应的色度值后，计算转化后的所述图像中每种色度值占所有色度值的权重值，所述计算方式包括：
c、先分别确定转化后的所述图像中每种色度值对应的面积，以及转化后的所述图像的总面积，然后将每种色度值对应的面积除以转化后的所述图像 的总面积，以得到每种色度值占转化后的所述图像中所有色度值的比例，最终将计算得到的比例作为每种色度值占所有色度值的权重值；
d、先确定转化后的所述图像中每个像素点对应的色度值，然后获取色度值相同的多个像素点，并分别将色度值相同的多个像素点的数目之和除以转化后的所述图像中的所有像素点的总数，以得到每种色度值占转化后的所述图像中所有色度值的比例，最终将计算得到的比例作为每种色度值占所有色度值的权重值。
步骤S124，根据每种色度值对应的权重值生成所述颜色选择界面。
在本实施例中，在得到每种色度值占转化后的所述图像中所有色度值对应的权重值时，生成多种色度值对应的颜色选择界面，其中，权重值越大的颜色，在所述颜色选择界面中占据的区域越多，权重值越小的颜色，在所述颜色选择界面中占据的区域越少。
在RGB颜色模型中，由于RGB图像会损失一部分亮度，比较鲜艳的色彩容易失真，容易导致所述图像生成的颜色选择界面不够准确，因此，在本实施例中，通过计算HSV颜色模型中每个像素点的颜色参数，得到所述图像对应的多种色度值，使得最终生成的颜色种类更加细致，有深色些的颜色，也有浅色些的颜色，对于较鲜艳的颜色也不容易失真，更加真实地反映了图像中包含的多种颜色，提高了拍照过程中，生成颜色选择界面的准确性。
进一步地，为了提高拍照的灵活性，基于第一或第二实施例提出本申请的拍照方法的第三实施例，在本实施例中，参照图11，所述步骤S20包括：
步骤S21，在接收到用户基于所述颜色选择界面输入的选择指令时，输出所述选择指令对应的色度值的容差范围选择界面；
步骤S22，在接收到用户基于所述容差范围选择界面选择的容差范围时，确定所述容差范围对应的色度值，并将确定的所述色度值作为所述选择指令对应的色度值。
在本实施例中，在根据所述图像中每个像素点的色度值生成多种色度值对应的颜色选择界面后，显示所述颜色选择界面，然后在接收到用户基于所述颜色选择界面输入的选择指令时，输出所述选择指令对应的色度值的容差 范围选择界面。所述容差范围选择界面的显示方式可以包括：a、显示容差范围输入框，以供用户基于所述容差范围输入框输入色值的容差范围；b、显示曲线界面，如抛物线界面，所述曲线界面中的曲线表示的是每个像素点构成的色度值，在接收到用户调整所述曲线界面中的曲线时，确定用户调整的范围，将用户调整的范围作为容差范围，并确定所述容差范围对应的色度值。为更好地理解本实施例，举例如下：以HSV颜色模型为例，在用户基于所述颜色选择界面输入的选择指令对应的色度值为240°，显示所述色度值240°的容差范围输入框，此时，用户在所述容差范围输入框中输入20°，则所述容差范围对应的色度值即为220°到260°，即选择的色度值不仅仅包括蓝色，还可能包括浅蓝色、天蓝色和深蓝色；若用户在所述容差范围输入框中输入40°，则所述容差范围对应的色度值即为200°到280°，即选择的色度值不仅仅包括蓝色，还可能包括群青色、靛青色、浅蓝色、天蓝色、和深蓝色等等几种颜色，即容差越大，相当于是以240°蓝色为中心线两边扩散的范围越大，若选择容差范围小，以240°蓝色为中心线两边扩散的范围越小，只会保留跟选择颜色相近的颜色。
在本实施例中，在接收到用户基于所述颜色选择界面输入的选择指令时，输出所述选择指令对应的色度值的容差范围选择界面，然后在接收到用户选择的容差范围时，确定所述容差范围对应的色度值，实现了获取颜色选择界面中的色度值时，不仅仅可以获取用户基于所述颜色选择界面选择的颜色，还可以获取选择的色度值相邻的色度值，使得色度值的获取更加灵活。
