优先权信息

技术领域
本发明涉及图像处理技术，尤其涉及控制方法、控制装置、电子装置和计算机可读存储介质。
背景技术
现有的一种图像传感器包括像素单元阵列和设置在像素单元阵列上的滤光片单元阵列，每个滤光片单元阵列覆盖对应一个感光像素单元，每个感光像素单元包括多个感光像素。工作时，可以控制图像传感器曝光输出合并图像，合并图像包括合并像素阵列，同一像素单元的多个感光像素合并输出作为一个合并像素。如此，可以提高合并图像的信噪比，然而，合并图像的解析度降低。当然，也可以控制图像传感器曝光输出高像素的色块图像，色块图像包括原始像素阵列，每个感光像素对应一个原始像素。然而，由于同一滤光片单元对应的多个原始像素颜色相同，同样无法提高色块图像的解析度。因此，需要通过插值计算的方式将高像素的色块图像转换成高像素的仿原图像，仿原图像可以包括呈拜耳阵列排布的仿原像素。仿原图像可以通过控制方法转换成真彩图像并保存下来。插值计算可以提高真彩图像的清晰度，然而耗费资源且耗时，导致拍摄时间加长，用户体验差。另一方面，具体应用时，用户往往只关注真彩图像中的主体部分的清晰度。

可以理解，本发明实施方式的控制方法采用第一插值算法处理色块图像的预定区域内的图像，采用第二插值算法处理合并图像。其中，预定区域可由用户进行输入和选择。第二插值算法的复杂度包括时间复杂度和空间复杂度，相较于第一插值算法，第二插值算法的时间复杂度和空间复杂度均小于第一插值算法。如此，在实际拍摄中，图像传感器21分别输出色块图像和合并图像，并且仅对色块图像的用户指定区域内的图像采用复杂度较大的第一插值算法进行图像处理，可以有效减少图像处理的数据和所需时间，还能提高用户关注的主体部分即预定区域内的图像的解析度，提升了用户体验。
请一并参阅图4至7，本发明实施方式的图像传感器21包括感光像素单元阵列212和设置在感光像素单元阵列212上的滤光片单元阵列211。
进一步地，感光像素单元阵列212包括多个感光像素单元212a，每个感光像素单元212a包括多个相邻的感光像素2121。每个感光像素2121包括一个感光器件21211和一个传输管21212，其中，感光器件21211可以是光电二极管，传输管21212可以是MOS晶体管。
滤光片单元阵列211包括多个滤光片单元211a，每个滤光片单元211a覆盖对应一个感光像素单元212a。
具体地，在某些示例中，滤光片单元阵列211包括拜耳阵列，也即是说，相邻的四个滤光片单元211a分别为一个红色滤光片单元、一个蓝色滤光片单元和两个绿色滤光片单元。
每一个感光像素单元212a对应同一颜色的滤光片211a，若一个感光像素单元212a中一共包括n个相邻的感光器件21211，那么一个滤光片单元211a覆盖一个感光像素单元212a中的n个感光器件21211，该滤光片单元211a可以是一体构造，也可以由n个独立的子滤光片组装连接在一起。
在某些实施方式中，每个感光像素单元212a包括四个相邻的感光像素2121，相邻两个感光像素2121共同构成一个感光像素子单元2120，感光像素子单元2120还包括一个源极跟随器21213和一个模数转换器21214。感光像素单元212a还包括一个加法器2122。其中，一个感光像素子单元2120中的每个传输管21212的一端电极被连接到对应感光器件21211的阴极电极，每个传输管21212的另一端被共同连接至源极跟随器21213的闸极电极，并通过源极跟随器21213源极电极连接至一个模数转换器21214。其中，源极跟随器21213可以是MOS晶体管。两个感光像素子单元2120通过各自的源极跟随器21213及模数转换器21214连接至加法器2122。
也即是说，本发明实施方式的图像传感器21的一个感光像素单元212a中相邻的四个感光器件21211共用一个同颜色的滤光片单元211a，每个感光器件21211对应连接一个传输管21212，相邻两个感光器件21211共用一个源极跟随器21213和一个模数转换器21214，相邻四个感光器件21211共用一个加法器2122。
进一步地，相邻四个感光器件21211呈2*2阵列排布。其中，一个感光像素子单元2120中的两个感光器件21211可以处于同一列。
在成像时，当同一滤光片单元211a下覆盖的两个感光像素子单元2120或者说四个感光器件21211同时曝光时，可以对像素进行合并进而可输出合并图像。
具体地，感光器件21211用于将光照转换为电荷，且产生的电荷与光照强度成比例关系，传输管21212用于根据控制信号来控制电路的导通或断开。当电路导通时，源极跟随器21213用于将感光器件21211经光照产生的电荷信号转换为电压信号。模数转换器21214用于电压信号转换为数字信号。加法器2122用于将两路数字信号相加共同输出，以供与图像传感器21相连的图像处理模块处理。
请参阅图8，以16M的图像传感器21举例来说，本发明实施方式的图像传感器21可以将16M的感光像素合并成4M，或者说，输出合并图像，合并后，感光像素的大小相当于变成了原来大小的4倍，从而提升了感光像素的感光度。此外，由于图像传感器21中的噪声大部分都是随机噪声，对于合并之前的感光像素来说，有可能其中一个或两个像素中存在噪点，而在将四个感光像素合并成一个大的感光像素后，减小了噪点对该大像素的影响，也即是减弱了噪声，提高了信噪比。
但在感光像素大小变大的同时，由于像素值降低，合并图像的解析度也将降低。
在成像时，当同一滤光片单元211a覆盖的四个感光器件21211依次曝光时，经过图像处理可以输出色块图像。
具体地，感光器件21211用于将光照转换为电荷，且产生的电荷与光照的强度成比 例关系，传输管21212用于根据控制信号来控制电路的导通或断开。当电路导通时，源极跟随器21213用于将感光器件21211经光照产生的电荷信号转换为电压信号。模数转换器21214用于将电压信号转换为数字信号以供与图像传感器21相连的图像处理模块处理。
请参阅图9，以16M的图像传感器21举例来说，本发明实施方式的图像传感器21还可以保持16M的感光像素输出，或者说输出色块图像，色块图像包括图像像素单元，图像像素单元包括2*2阵列排布的原始像素，该原始像素的大小与感光像素大小相同，然而由于覆盖相邻四个感光器件21211的滤光片单元211a为同一颜色，也即是说，虽然四个感光器件21211分别曝光，但其覆盖的滤光片单元211a颜色相同，因此，输出的每个图像像素单元的相邻四个原始像素颜色相同，仍然无法提高图像的解析度。
本发明实施方式的控制方法，用于对输出的色块图像进行处理，以得到仿原图像。
可以理解，合并图像在输出时，四个相邻的同色的感光像素以合并像素输出，如此，合并图像中的四个相邻的合并像素仍可看作是典型的拜耳阵列，可以直接被图像处理模块接收进行处理以输出真彩图像。而色块图像在输出时每个感光像素分别输出，由于相邻四个感光像素颜色相同，因此，一个图像像素单元的四个相邻原始像素的颜色相同，是非典型的拜耳阵列。而图像处理模块无法对非典型拜耳阵列直接进行处理，也即是说，在图像传感器21采用统一图像处理模式时，为兼容两种模式的真彩图像输出即合并模式下的真彩图像输出及色块模式下的真彩图像输出，需将色块图像转换为仿原图像，或者说将非典型拜耳阵列的图像像素单元转换为典型的拜耳阵列的像素排布。
仿原图像包括呈拜耳阵列排布的仿原像素。仿原像素包括当前像素，原始像素包括与当前像素对应的关联像素。
本发明实施方式的控制方法分别输出色块图像和合并图像。
对于一帧色块图像的预定区域内的图像，先将该色块图像的预定区域转换成拜耳图像阵列，再利用第一插值算法进行图像处理。具体地，请参阅图10，以图10为例，当前像素为R3’3’和R5’5’，对应的关联像素分别为R33和R55。
在获取当前像素R3’3’时，由于R3’3’与对应的关联像素R33的颜色相同，因此在转换时直接将R33的像素值作为R3’3’的像素值。
在获取当前像素R5’5’时，由于R5’5’与对应的关联像素B55的颜色不相同，显然不能直接将B55的像素值作为R5’5’的像素值，需要根据R5’5’的关联像素单元通过插值的方式计算得到。
需要说明的是，以上及下文中的像素值应当广义理解为该像素的颜色属性数值，例如色彩值。
关联像素单元包括多个，例如4个，颜色与当前像素相同且与当前像素相邻的图像像素单元中的原始像素。
需要说明的是，此处相邻应做广义理解，以图10为例，R5’5’对应的关联像素为B55，与B55所在的图像像素单元相邻的且与R5’5’颜色相同的关联像素单元所在的图像像素单元分别为R44、R74、R47、R77所在的图像像素单元，而并非在空间上距离B55所在的图像像素单元更远的其他的红色图像像素单元。其中，与B55在空间上距离最近的红色原始像素分别为R44、R74、R47和R77，也即是说，R5’5’的关联像素单元由R44、R74、R47和R77组成，R5’5’与R44、R74、R47和R77的颜色相同且相邻。
如此，针对不同情况的当前像素，采用不同方式的将原始像素转换为仿原像素，从而将色块图像转换为仿原图像，由于拍摄图像时，采用了特殊的拜耳阵列结构的滤光片，提高了图像信噪比，并且在图像处理过程中，通过第一插值算法对色块图像进行插值处理，提高了图像的分辨率及解析度。
请参阅图11，在某些实施方式中，步骤S137包括以下步骤：
S1371：计算关联像素各个方向上的渐变量；
S1372：计算关联像素各个方向上的权重；和
S1373：根据渐变量及权重计算当前像素的像素值。
请参阅图12，在某些实施方式中，第二计算模块137包括第一计算单元1371、第二计算单元1372和第三计算单元1373。第一计算单元1371用于计算关联像素各个方向上的渐变量；第二计算单元1372用于计算关联像素各个方向上的权重；第三计算单元1373用于根据渐变量及权重计算当前像素的像素值。
也即是说，步骤S1371可以由第一计算单元1371实现，步骤S1372可以由第二计算单元1372实现，步骤S1373可以由第三计算单元1373实现。
具体地，第一插值算法是参考图像在不同方向上的能量渐变，将与当前像素对应的颜色相同且相邻的关联像素单元依据在不同方向上的渐变权重大小，通过线性插值的方式计算得到当前像素的像素值。其中，在能量变化量较小的方向上，参考比重较大，因此，在插值计算时的权重较大。
在某些示例中，为方便计算，仅考虑水平和垂直方向。
R5’5’由R44、R74、R47和R77插值得到，而在水平和垂直方向上并不存在颜色相同的原始像素，因此需首根据关联像素单元计算在水平和垂直方向上该颜色的分量。 其中，水平方向上的分量为R45和R75、垂直方向的分量为R54和R57可以分别通过R44、R74、R47和R77计算得到。
具体地，R45＝R44*2/3+R47*1/3，R75＝2/3*R74+1/3*R77，R54＝2/3*R44+1/3*R74，R57＝2/3*R47+1/3*R77。
然后，分别计算在水平和垂直方向的渐变量及权重，也即是说，根据该颜色在不同方向的渐变量，以确定在插值时不同方向的参考权重，在渐变量小的方向，权重较大，而在渐变量较大的方向，权重较小。其中，在水平方向的渐变量X1＝|R45-R75|，在垂直方向上的渐变量X2＝|R54-R57|，W1＝X1/(X1+X2)，W2＝X2/(X1+X2)。
如此，根据上述可计算得到，R5’5’＝(2/3*R45+1/3*R75)*W2+(2/3*R54+1/3*R57)*W1。可以理解，若X1大于X2，则W1大于W2，因此计算时水平方向的权重为W2，而垂直方向的权重为W1，反之亦反。
如此，可根据第一插值算法计算得到当前像素的像素值。依据上述对关联像素的处理方式，可将原始像素转换为呈典型拜耳阵列排布的仿原像素，也即是说，相邻的四个2*2阵列的仿原像素包括一个红色仿原像素，两个绿色仿原像素和一个蓝色仿原像素。
需要说明的是，第一插值算法包括但不限于本实施例中公开的在计算时仅考虑垂直和水平两个方向相同颜色的像素值的方式，例如还可以参考其他颜色的像素值。
请参阅图13，在某些实施方式中，在步骤S137前包括步骤：
S136a，对色块图像做白平衡补偿；
步骤S137后包括步骤：
S138a：对仿原图像做白平衡补偿还原。
请参阅图14，在某些实施方式中，第一转换模块13包括白平衡补偿模块136a和白平衡补偿还原模块138a。白平衡补偿模块136a用于对色块图像做白平衡补偿，白平衡补偿还原模块138a用于对仿原图像做白平衡补偿还原。
也即是说，步骤S136a可以由白平衡补偿模块136a实现，步骤S138a可以由白平衡补偿还原模块138a实现。
具体地，在一些示例中，在将色块图像转换为仿原图像的过程中，在插值时，红色和蓝色仿原像素往往不仅参考与其颜色相同的通道的原始像素的颜色，还会参考绿色通道的原始像素的颜色权重，因此，在插值前需要进行白平衡补偿，以在插值计算中排除白平衡的影响。为了不破坏色块图像的白平衡，因此，在插值之后需要将仿原图像进行白平衡补偿还原，还原时根据在补偿中红色、绿色及蓝色的增益值进行还原。
如此，可排除在插值过程中白平衡的影响，并且能够使得插值后得到的仿原图像保 持色块图像的白平衡。
请再参阅图13，在某些实施方式中，步骤S137前包括步骤：
S136b：对色块图像做坏点补偿。
请再参阅图14，在某些实施方式中，第一转换模块13包括坏点补偿模块136b。
也即是说，步骤S136b可以由坏点补偿模块136b实现。
可以理解，受限于制造工艺，图像传感器21可能会存在坏点，坏点通常不随感光度变化而始终呈现同一颜色，坏点的存在将影响图像质量，因此，为保证插值的准确，不受坏点的影响，需要在插值前进行坏点补偿。
具体地，坏点补偿过程中，可以对原始像素进行检测，当检测到某一原始像素为坏点时，可根据其所在的图像像素单元的其他原始像的像素值进行坏点补偿。
如此，可排除坏点对插值处理的影响，提高图像质量。
请再参阅图13，在某些实施方式中，步骤S137前包括步骤：
S136c：对色块图像做串扰补偿。
请再参阅图14，在某些实施方式中，第一转换模块13包括串扰补偿模块136c。
也即是说，步骤S136c可以由串扰模块136c实现。
具体的，一个感光像素单元中的四个感光像素覆盖同一颜色的滤光片，而感光像素之间可能存在感光度的差异，以至于以仿原图像转换输出的真彩图像中的纯色区域会出现固定型谱噪声，影响图像的质量。因此，需要对色块图像进行串扰补偿。
请再参阅图13，在某些实施方式中，步骤S137后包括步骤：
S138b：对仿原图像进行镜片阴影校正、去马赛克、降噪和边缘锐化处理。
请再参阅图14，在某些实施方式中，第一转换模块13还包括第一处理模块138b。
也即是说，步骤S138b可以由第一处理模块138b实现。
可以理解，将色块图像转换为仿原图像后，仿原像素排布为典型的拜耳阵列，可采用第一处理模块138b进行处理，处理过程中包括镜片阴影校正、去马赛克、降噪和边缘锐化处理，如此，处理后即可得到真彩图像输出给用户。
对于一帧合并图像的预定区域外的图像，请参阅图8，以图8为例，由于合并图像为非典型的拜耳阵列，图像传感器21将16M的感光像素合并成4M直接输出，因此，为便于后续的色块图像与合并图像的合成，需要先利用第二插值算法将合并图像拉伸放大以转换成大小与色块图像相同的还原图像。请参阅图15，对色块图像的预定区域内图像利用第一插值算法处理成为仿原图像，对合并图像利用第二插值算法处理成为还原图像后，将两幅图像进行合成以得到合并仿原图像。合并仿原图像中预定区域内 的图像具有较高的解析度。
请参阅图16，在某些实施方式中，步骤S12包括以下步骤：
S121：利用第三插值算法将合并图像转换成预览图像，第三插值算法包括第二插值算法；
S122：控制触摸屏显示预览图像；和
S123：处理触摸屏上的用户输入确定预定区域。
请参阅图17，在某些实施方式中，选定模块12包括第二转换模块121、显示模块122及第二处理模块123。第二转换模块121用于利用第三插值算法将合并图像转换成预览图像，第三插值算法包括第二插值算法，显示模块122用于控制触摸屏显示预览图像，第二处理模块123用于处理触摸屏上的用户输入确定预定区域。
也即是说，步骤S121可以由第二转换模块121实现，步骤S122可以由显示模块122实现，步骤S123可以由第二处理模块123实现。
可以理解，用户选择预定区域时，需要在预览图像中进行选取。第二转换模块121将合并图像转换成预览图像并由显示模块122显示。其中，合并图像转换成预览图像的过程采用第三插值算法进行计算。第三插值算法包括第二插值算法和双线性插值法。转换过程中，首先利用第二插值算法将合并图像转换成拜耳阵列的还原图像，再利用双线性插值法将仿原图像转换成真彩图像。如此，用户可进行预览，便于用户选取预定区域。
需要说明的是，还原图像转换成真彩图像的算法不限定于双线性插值法，也可采用其他插值算法进行计算。
请参阅图18，在某些实施方式中，步骤S123包括以下步骤：
S1231：将预览图像划分为阵列排布的扩展单元；
S1232：处理用户输入以识别触摸位置；
S1233：确定触摸位置所在的原点扩展单元，扩展单元包括原点扩展单元；
S1234：计算以原点扩展单元为中心向外依次扩展的每个扩展单元的反差值；
S1235：当反差值超过预定阈值时确定对应的扩展单元为边缘扩展单元，扩展单元包括边缘扩展单元；和
S1236：确定边缘扩展单元围成的区域为预定区域。
请参阅图19，在某些实施方式中，第二处理模块123包括划分单元1231、第一识别单元1232、定点单元1233、第四计算单元1234、第一处理单元1235、第二处理单元1236。划分单元1231用于将预览图像划分为阵列排布的扩展单元，第一识别单元 1232用于识别用户输入以识别触摸位置，定点单元1233用于确定触摸位置所在的原点扩展单元，扩展单元包括原点扩展单元，第四计算单元1234用于计算以原点扩展单元为中心依次向外扩展的每个扩展单元的反差值，第一处理单元1235用于当反差值超过预定阈值时确定对应的扩展单元为边缘扩展单元，扩展单元包括边缘扩展单元，第二处理单元1236用于确定边缘扩展单元围成的区域为预定区域。
也即是说，步骤S1231可以由划分单元1231实现，步骤S1232可以由第一识别单元实现，步骤S1233可以由定点单元1233实现，步骤S1234可以由第四计算单元1234实现，步骤S1235可以由第一处理单元1235实现，步骤S1236可以由第二处理单元1236实现。
具体地，请参阅图20，以图20为例，黑色圆点为用户的触摸位置，以该触摸位置为原点扩展单元向外扩展，图中每个方框即为一个扩展单元。随后比较每个扩展单元的反差值与预设阈值的大小，反差值大于预设阈值的扩展单元即为边缘扩展单元。图19中所示人脸的边缘部分所在的扩展单元的反差值均大于预设阈值，也即是说，图中人脸边缘部分所在的扩展单元即为边缘扩展单元，图中灰色方框为边缘扩展单元。如此，将多个边缘扩展单元围成的区域作为预定区域，预定区域是由用户指定的处理区域即用户关注的主体部分，采用第一插值算法对该区域内的图像进行处理，提升用户关注的主体部分的图像的解析度，提升用户体验。
请参阅图21，在某些实施方式中，步骤S123包括以下步骤：
S127：处理用户输入以识别触摸位置；和
S128：以触摸位置为中心向外扩展预定形状的区域作为预定区域。
请参阅图22，在某些实施方式中，第二处理模块123包括第二识别单元1237和扩展单元1238。第二识别单元1237用于处理用户输入以识别触摸位置，扩展单元1238用于以触摸位置为中心向外扩展预定形状的区域作为预定区域。
也即是说，步骤S1237可以由第二识别单元1237实现，步骤S1238可以由扩展单元1238实现。
请参阅图23，在某些实施方式中，步骤S1238包括以下步骤：
S12381：处理用户输入以确定预定形状。
请参阅图24，在某些实施方式中，扩展单元1238包括第三处理单元12381，第三处理单元12381用于处理用户输入以确定预定形状。
也即是说，步骤S12381可以由第三处理单元12381实现。
具体地，请参阅图25，图中的黑色圆点为用户的触摸位置。以该触摸位置为中心， 向外扩展圆形的区域以生成预定区域。图中所示以圆形扩展的预定区域包括了整个人脸部分，可以对人脸部分采用第一插值算法以提高人脸部分的解析度。
需要说明的是，在其它具体实施例中，扩展的预定形状还可以是矩形、方形或其他形状，用户可以根据实际所需对扩展的预定形状进行大小的调整以及拖动。此外，用户指定预定区域的方式还包括用户直接在触摸屏上勾画出一个任意形状作为预定区域，或者用户在触摸屏上选取几个点，这几个点连线后围成的区域作为预定区域后进行第一插值算法的图像处理。如此，便于用户自主选择关注的主体部分以提高主体部分的清晰度，从而进一步提升用户体验。
