具体实施方式
为使本发明的目的、技术方案和优点更加清楚，下面将结合本发明具体实施例及相应的附图对本发明技术方案进行清楚、完整地描述。显然，所描述的实施例仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
以下结合附图，详细说明本发明各实施例提供的技术方案。
请参见图1，图1为本发明一个实施例提供的一种检测电路的模块示意图之一，如图1所示，该电路包括以下模块：电源11、光电二极管12、驱动电路13以及控制单元14。
在本发明实施例中，电源11可以与光电二极管12相连，在一个示例中，电源11可以与光电二极管12的负极相连。
当电源11与光电二极管12的负极相连时，若光电二极管12处于导通状态，如处于光信号采样状态，则电源11输出的电流可以通过光电二极管12；若光电二极管12处于未导通状态，则电源11输出的电流可以无法通过光电二极管12。
电源11可以通过光电二极管12与驱动电路13以及控制单元14连接，当电源11与光电二极管12的负极相连时，若光电二极管12处于导通状态，则电源11输出的电流可以通过光电二极管12输入至驱动电路13以及控制单元14；若光电二极管12处于未导通状态，则电源11输出的电流无法输入至 驱动电路13以及控制单元14。
在本发明实施例中，当处于导通状态时，光电二极管11可以基于光源输出电流，即光电二极管11可以对光源进行光信号采样，并将采样到的光信号转换为电信号，以产生电流。
在一个实施例中，光电二极管11可以包括光谱响应的波长范围满足380nm(纳米)至780nm，且响应速度不大于100ns(纳秒)的光电二极管。
在一个示例中，光电二极管11可以包括光谱响应的波长范围满足400nm至730nm，或满足420nm至700nm，且响应速度不大于100ns(纳秒)的光电二极管。
在另一个示例中，光电二极管11可以包括光谱响应的波长范围满足380nm至780nm，且响应速度不大于20ns(纳秒)的光电二极管。
光电二极管11产生电流后，可以输出电流。
驱动电路12可以与光电二极管11串联，在一个示例中，驱动电路12可以与光电二极管11的正极相连，此时，光电二极管12的负极可以与电源14连接，光电二极管11输出的电流可以流向电源14。
需要说明的是，电源11输出的电流流向光电二极管12，电流的方向可以如图3的方向1所示。光电二极管12输出的电流流向电源11，电路方向可以如图3的方向2所示。由于电源11输出的电流的方向，与光电二极管11输出的电流的方向相反，因此，输入至驱动电路13的电流可以为电源11输出的电流，与光电二极管11输出的电流的差。
驱动电路13中可以包括多路电路，如图2所示，其中，多路电路具有不同的照度相关系数。在本发明实施例中，照度相关系数可以指示光电二极管12基于光源输出的电流在电路中产生的电压与该光源的照度之间的对应关系，在一个示例中，照度相关系数可以用于根据光电二极管12输出的电流在电路中产生的电压，来确定光源的照度。
例如，光电二极管12输出的电流在电路中产生的电压可以为0.9V，该电路设置的照度相关系数可以为1000lx/V，则可以确定光源的照度为0.9V*1000lx/V＝900lx。
在一个示例中，针对阻值或等效阻值不同的阻性元器件，相同的电压以及照度之间的照度相关系数可以不同。故在本发明实施例中，可以先确定驱动电路13的每一路电路中的阻性元器件的阻值或等效阻值，然后，根据校正设备，如标准照度计等，来设置驱动电路13的每路电路的照度相关系数。
例如，可以设置驱动电路13中的一路电路的阻性元器件的阻值为10KΩ，则可以根据标准照度计来计算出该路电路的照度校正系数为10000lx/V；可以设置驱动电路13中的一路电路的阻性元器件的阻值为100KΩ，则可以根据标准照度计来计算出该路电路的照度校正系数为1000lx/V；可以设置驱动电路13中的一路电路的阻性元器件的阻值为1MΩ，则可以根据标准照度计来计算出该路电路的照度校正系数为100lx/V。
在本发明实施例中，驱动电路13可以与控制单元14相连，控制单元14可以在驱动电路13的多个电路中，选择匹配的照度相关系数的电路以控制输出电压在指定电压范围。
在一个示例中，控制单元14可以控制驱动电路13的至少一路电路与光电二极管12连通，此时，驱动电路13可以根据输入的电流，以及该电路中的阻性元器件的阻值或等效阻值，来生成输出电压。
需要说明的是，本发明实施例中，控制单元14可以控制驱动电路13中的一路电路与光电二极管12连通，也可以控制驱动电路13中的多路电路同时与光电二极管12连通，本发明实施例对此不做限制。当与光电二极管11连通的电路不同时，驱动电路13基于该不同的电路中的阻性元器件，以及，输入的电流，生成的输出电压不同。
在本发明实施例中，如图3所示，控制单元14还可以与光电二极管12相连，并控制光电二极管12的受光面对光源进行光信号采样。在一个示例中，控制单元14可以先确定采样参数，然后，根据该预先确定的采样参数，来控制光电二极管的受光面进行受光。其中，采样参数包括采样周期和采样数量。
在本发明实施例中，驱动电路13的每路电路的阻值或等效阻值不同。
在本发明实施例中，可以在光电二极管基于光源输出电流时，基于光电二极管输出的电流、电源输出的电流以及驱动电路中的阻性元器件来生成输 出电压，然后，可以通过控制单元来从驱动电路中选择匹配的照度相关系数的电路以控制输出电压在指定电压范围。当光源存在频闪时，在一个采样周期中的多次测量中电压的测得值会出现一个周期性的变化，因此可以基于由光源确定的电压值的大小变化情况来检测光源频闪，从而，可以实现对光源频闪的检测。
请参见图4，图4为本发明一个实施例提供的一种光源频闪的检测装置的模块示意图之一，如图4所示，该电路包括以下模块：检测电路41、V(λ)滤光片42以及计算单元43。
在本发明实施例中，V(λ)滤光片12可以设置在检测电路41中的光电二极管12的受光面前，以在光电二极管12受光前，对光源进行滤光。
在本发明实施例中，检测电路41可以与计算单元43相连，并将产生的电压输入至计算单元43，计算单元43可以根据检测电路41的驱动电路13输出的电压，来确定用于表征所述光源的光源频闪参数的计算单元。
在本发明实施例中，光源频闪参数可以包括闪烁百分比和/或闪烁指数。
当光源频闪参数包括闪烁百分比时，计算单元43可以根据如下所示的公式来计算与光源对应的闪烁百分比。
闪烁百分比(％)＝(Ex_max-Ex_min)/(Ex_max+Ex_min)
其中，Ex_max是在一个检测周期中测得的光源的最大照度值，Ex_min是在该相同的检测周期中测得的光源的最小照度值。
当光源频闪参数包括闪烁指数时，计算单元43可以根据如下所示的公式来计算与光源对应的闪烁指数。
闪烁指数＝ΣEx_u/Σ(Ex_u–Ex_l)
其中，Ex_u是在一个检测周期中测得的高于平均照度值的照度值，Ex_l是在该相同的检测周期中测得的低于平均照度值的照度值，而平均照度值可以为在该相同的检测周期内测得的所有照度值的平均值。
而在计算光源的频率时，计算单元43可以通过现有技术，如傅里叶变化，根据检测电路41输出的电压值，来计算光源的频率。
在本发明实施例中，如图5所示，该光源频闪的检测装置还可以包括调 整单元44，其中，调整单元44可以与计算单元43，以及检测电路41中的光电二极管12连接，基于计算单元43输出的光源频闪参数，来调整光电二极管12的光源的采样参数。
在本发明实施例中，可以通过V(λ)滤光片来对检测电路检测的光源进行滤光，然后，可以通过计算单元来根据检测电路的驱动电路输出的电压，来确定用于表征光源的光源频闪的参数，从而基于确定的参数来实现对光源频闪的检测。
请参见图6，图6为本发明一个实施例提供的一种光源频闪的检测方法的流程示意图之一，如图6所示，该方法包括以下步骤。
步骤602：根据驱动电路输出的电压是否满足指定电压范围，从驱动电路中确定目标电路；目标电路包括至少一路电路；指定电压范围是基于驱动电路中连接光电二极管的电路的电源电压确定的。
步骤604：确定目标电路连接光电二极管时，驱动电路输出的电压。
步骤606：根据驱动电路多次输出的电压，确定用于表征光源的光源频闪的参数。
在本发明实施例中，可以根据驱动电路输出的电压是否满足指定电压范围，从驱动电路中确定目标电路。其中，驱动电路中包括多路电路，不同电路中的阻性元器件的阻值或等效阻值不同。
在一个实施例中，可以在驱动电路中预先设置多个电路，其中，该设置的多个电路的阻性元器件的等效电阻值不同，例如，可以预先设置两个电路：电路1以及电路2，其中，电路1可以包括1个阻性元器件，该阻性元器件的电阻值为10KΩ，则可以确定电路1的阻性元器件的电阻值为：10KΩ；电路2可以包括2个串联的阻性元器件，该2个阻性元器件的电阻值分别为：10KΩ、5KΩ，则可以确定电路2的阻性元器件的等效电阻值为：15KΩ。
在本发明实施例中，光电二极管可以对光源进行光信号采样，并将采样到的光信号转换为电信号，以形成电流，然后，光电二极管可以向电源输出电流，同时，电源可以向光电二极管输出电流，电源输出的部分电流可以用于“抵消”光电二极管输出的电流，而电源输出的其他电流可以通过光电二 极管输入至驱动电路中。
输入至驱动电路中的电流可以在驱动电路的阻性元器件上产生的电压，然后，可以根据驱动电路输出的电压是否满足指定电压范围，从驱动电路中确定目标电路。其中，指定电压范围是基于驱动电路中连接光电二极管的电路的电源电压确定的。
在一个示例中，驱动电路中连接光电二极管的电路的电源电压可以为V power，则指定电压范围可以设置为{V low，V high}，其中，V high可以设置为0.9V power或1V power；V low可以设置为(0.01～0.001)V high。
例如，驱动电路中连接光电二极管的电路的电源电压V power可以为10V，则V high可以设置为0.9V power，即9V，而V low可以设置为0.005V high，即0.0045V，则此时，指定电压范围可以设置为{0.0045V，9V}。
在确定指定电压范围后，可以确定驱动电路输出的电压是否满足该指定电压范围，即确定的该电压值处于落入该指定电压范围中。当确定的该电压值满足该指定电压范围时，可以确定目标电路连接所述光电二极管时，所述驱动电路输出的电压，并根据驱动电路输出的电压，确定用于表征光源的光源频闪的参数。
在本发明实施例中，在根据驱动电路输出的电压是否满足指定电压范围，来从驱动电路中确定目标电路时，可以依次从驱动电路中选取至少一路电路与光电二极管连接，并获取驱动电路输出的电压，当驱动电路输出的电压满足指定电压范围时，将驱动电路中连接光电二极管的电路确定为目标电路。
在一个示例中，可以从驱动电路中选取至少一路电路来与光电二极管连接，并获取驱动电路输出的电压，然后，可以确定驱动电路输出的电压是否满足指定电压范围，若满足，则可以将该至少一路电路确定为目标电路；若不满足，则可以选取其他电路与光电二极管连接，并获取驱动电路输出的电压，然后，可以确定驱动电路输出的电压是否满足指定电压范围，若满足，则可以将该新选取的电路确定为目标电路；若不满足，则可以继续选取，直到从驱动电路中确定目标电路。
在本发明实施例中，当驱动电路输出的电压不满足指定电压范围时，可以根据产生电压值的阻性元器件的阻值或等效阻值，以及其他电路的阻性元器件的阻值或等效阻值，来从其他电路中确定候选电路，其中，其他电路可以为至少一个电路中除连接光电二极管的电路以外的电路。
具体地，当驱动电路输出的电压超出指定电压范围时，可以根据产生电压值的阻性元器件的阻值或等效阻值，以及其他电路的阻性元器件的阻值或等效阻值，来从其他电路中确定第一候选电路，其中，第一候选电路的阻性元器件的等效电阻值小于产生电压值的阻性元器件的等效电阻值。
例如，驱动电路中的电路1接通光电二极管时，驱动电路输出的电压可以超出了指定电压范围，其中，电路1的阻性元器件的电阻值为100KΩ，可以从其他电路中确定第一候选电路，其他电路可以包括电路2和电路3，其中，电路2的阻性元器件的电阻值为10KΩ，电路3的阻性元器件的等效电阻值为1MΩ，则可以将电路2确定为第一候选电路。
对应地，当驱动电路输出的电压超出指定电压范围时，可以根据产生电压值的阻性元器件的阻值或等效阻值，以及其他电路的阻性元器件的阻值或等效阻值，来从其他电路中确定第二候选电路，其中，第二候选电路的阻性元器件的等效电阻值小于产生电压值的阻性元器件的等效电阻值。
例如，驱动电路中的电路2接通光电二极管时，驱动电路输出的电压可以低于了指定电压范围，其中，电路2的阻性元器件的电阻值为100KΩ，可以从其他电路中确定第二候选电路，其他电路可以包括电路2和电路3，其中，电路2的阻性元器件的电阻值为10KΩ，电路3的阻性元器件的等效电阻值为1MΩ，则可以将电路3确定为第二候选电路。
在确定了候选电路后，可以依次从候选电路中选取至少一路电路与光电二极管连接，并获取驱动电路输出的电压，并在驱动电路输出的电压满足指定电压范围时，将驱动电路中连接光电二极管的电路确定为目标电路。
需要说明的是，当检测电路检测的光源信号较强时，光电二极管基于该光源产生的电流也越大，若该较大的电流超出了驱动电路的当前接通光电二极管的电路的电源输出的电流，则电源输出的电流会基本被“抵消”掉，此 时，将没有电流，或有极小的电流流入驱动电路，若驱动电路的当前接通光电二极管的电路中的阻性元器件的阻值或等效阻值较小，则驱动电路仅能输出较小的电压，低于电压检测范围，从而导致检测出的电压值不准确，由于后续需要根据检测出的电压值来确定目标光源的光源频闪的检测值，因此，若检测出的电压值不准确，则很有可能会导致后续确定的检测值不准确，从而使得目标光源的光源频闪的检测结果不准确。
而本发明实施例中，可以设置多个电路，而该多个电路中的阻性元器件的等效电阻值不同，当光源对应的电信号较强时，可以从驱动电路中选取包括较大阻值或等效阻值的阻性元器件的电路，由于该电路中的阻性元器件的等效电阻值较大，因此，驱动电路输出的电压较大，不会低于电压检测范围，此时，检测出的该电信号在该阻性元器件上产生的电压与该电信号在该阻性元器件上产生的真实电压一致，因此，后续根据该检测出的电压值来确定用于表征光源的光源频闪的参数，确定的检测参数也较为准确，相应地，基于该检测参数对光源的光源频闪的检测结果准确度也较高。
在本发明实施例中，在获取驱动电路多次输出的电压后，可以根据驱动电路输出的电压，确定用于表征光源的光源频闪的参数，具体地，可以获取驱动电路在一个检测周期内多次输出的电压，并根据驱动电路在该检测周期内多次输出的电压，来确定用于表征光源的光源频闪的参数。
在一个实施例中，可以先确定目标电路的照度校正系数，然后，根据照度校正系数，以及驱动电路多次输出的电压，来确定光源的多个照度，以及根据光源的多个照度，来确定用于表征光源的光源频闪的参数。由于该内容已在上述实施例中详述，故本发明实施例在此不再赘述。
在确定光源的多个照度后，可以根据该多个照度，来确定用于表征光源的光源频闪的参数。
在一个实施例中，用于表征光源的光源频闪的参数可以包括光源的频率值，以及光源的闪烁百分比和/或闪烁指数。
在一个示例中，根据光源的照度，确定用于表征光源的光源频闪的参数时，可以根据光源的照度来确定光源的闪烁百分比和/或闪烁指数。
由于根据光源的照度来确定光源的闪烁百分比和/或闪烁指数的具体过程已在上述实施例中详述，故本发明实施例在此不再赘述。
在本发明实施例中，可以根据光电二极管对光源的采样参数，来确定有效频率值范围。其中，采样参数值可以包括采样周期和采样数量。
在一个示例中，可以根据采样参数值中的采样周期来确定有效频率范围中的最大频率，以及根据采样参数值中的采样周期和采样数量来确定总采样时间，并基于确定的总采样时间来确定有效频率范围中的最小频率。
例如，采样参数值可以包括：采样周期为25μs，采样数量为1024个，则可以确定总采样时间为采样周期以及采样数量的乘积25.6ms，则有效频率范围中的最小频率可以为1/25.6ms＝39Hz；考虑到一个采样周期内至少要采集两个信号，因此，有效频率范围中的最大频率可以为1/50μs＝20KHz，由此可以确定有效频率范围为{39Hz，20KHz}。
在确定有效频率范围后，可以确定光源的频率。在一个实施例中，可以通过现有技术，如傅里叶变换，根据驱动电路输出的电压来确定与光源的频率。
在确定有效频率范围后，可以确定目标光源的频率值是否满足上述确定的有效频率范围，当光源的频率值满足上述确定的有效频率范围时，根据所述驱动电路输出的电压是否满足指定电压范围，来从所述驱动电路中确定目标电路。
在本发明实施例中，当光源的频率不满足有效频率范围时，根据光源的频率，以及有效频率值范围，对采样参数进行调整。
具体地，当光源的频率值超出有效频率范围时，可以缩小采样参数值中的采样周期；当光源的频率低于有效频率范围时，可以增大采样参数值中的采样数量。
在对采样参数值进行调整后，可以根据调整后的采样参数值对光源进行光信号采样，并将采样到的光信号转换为电信号，形成电流，并将该电流输入至驱动电路中，以使得驱动电路基于该电路输出电压，以及根据驱动电路输出的该电压，来确定用于表征光源的光源频闪的参数。
在本发明实施例中，可以根据驱动电路输出的电压是否满足指定电压范围，从驱动电路中确定目标电路，目标电路包括至少一路电路，指定电压范围是基于驱动电路中连接光电二极管的电路的电源电压确定的，确定目标电路连接所述光电二极管时驱动电路输出的电压，并根据驱动电路输出的电压，确定用于表征光源的光源频闪的参数。
由上述内容可知，本发明实施例中，可以通过预先设定的多个电路的阻性元器件，以及输入至驱动电路的电流来产生符合有效电压值范围的电压，使得针对该电压值的检测结果更准确，从而使得后续根据该检测出的电压值来确定用于表征光源的光源频闪的参数，确定的检测参数也较为准确，相应地，基于该检测参数对光源的光源频闪的检测结果准确度也较高。

在20世纪90年代，对于一个技术的改进可以很明显地区分是硬件上的 改进(例如，对二极管、晶体管、开关等电路结构的改进)还是软件上的改进(对于方法流程的改进)。然而，随着技术的发展，当今的很多方法流程的改进已经可以视为硬件电路结构的直接改进。设计人员几乎都通过将改进的方法流程编程到硬件电路中来得到相应的硬件电路结构。因此，不能说一个方法流程的改进就不能用硬件实体模块来实现。例如，可编程逻辑器件(Programmable Logic Device，PLD)(例如现场可编程门阵列(Field Programmable Gate Array，FPGA))就是这样一种集成电路，其逻辑功能由用户对器件编程来确定。由设计人员自行编程来把一个数字系统“集成”在一片PLD上，而不需要请芯片制造厂商来设计和制作专用的集成电路芯片。而且，如今，取代手工地制作集成电路芯片，这种编程也多半改用“逻辑编译器(logic compiler)”软件来实现，它与程序开发撰写时所用的软件编译器相类似，而要编译之前的原始代码也得用特定的编程语言来撰写，此称之为硬件描述语言(Hardware Description Language，HDL)，而HDL也并非仅有一种，而是有许多种，如ABEL(Advanced Boolean Expression Language)、AHDL(Altera Hardware Description Language)、Confluence、CUPL(Cornell University Programming Language)、HDCal、JHDL(Java Hardware Description Language)、Lava、Lola、MyHDL、PALASM、RHDL(Ruby Hardware Description Language)等，目前最普遍使用的是VHDL(Very-High-Speed Integrated Circuit Hardware Description Language)与Verilog。本领域技术人员也应该清楚，只需要将方法流程用上述几种硬件描述语言稍作逻辑编程并编程到集成电路中，就可以很容易得到实现该逻辑方法流程的硬件电路。
控制器可以按任何适当的方式实现，例如，控制器可以采取例如微处理器或处理器以及存储可由该(微)处理器执行的计算机可读程序代码(例如软件或固件)的计算机可读介质、逻辑门、开关、专用集成电路(Application Specific Integrated Circuit，ASIC)、可编程逻辑控制器和嵌入微控制器的形式，控制器的例子包括但不限于以下微控制器：ARC 625D、Atmel AT91SAM、Microchip PIC18F26K20以及Silicone Labs C8051F320，存储器控制器还可以被实现为存储器的控制逻辑的一部分。本领域技术人员也知道，除了以纯计 算机可读程序代码方式实现控制器以外，完全可以通过将方法步骤进行逻辑编程来使得控制器以逻辑门、开关、专用集成电路、可编程逻辑控制器和嵌入微控制器等的形式来实现相同功能。因此这种控制器可以被认为是一种硬件部件，而对其内包括的用于实现各种功能的装置也可以视为硬件部件内的结构。或者甚至，可以将用于实现各种功能的装置视为既可以是实现方法的软件模块又可以是硬件部件内的结构。
上述实施例阐明的系统、装置、模块或单元，具体可以由计算机芯片或实体实现，或者由具有某种功能的产品来实现。一种典型的实现设备为计算机。具体的，计算机例如可以为个人计算机、膝上型计算机、蜂窝电话、相机电话、智能电话、个人数字助理、媒体播放器、导航设备、电子邮件设备、游戏控制台、平板计算机、可穿戴设备或者这些设备中的任何设备的组合。

这些计算机程序指令也可存储在能引导计算机或其他可编程数据处理设备以特定方式工作的计算机可读存储器中，使得存储在该计算机可读存储器 中的指令产生包括指令装置的制造品，该指令装置实现在流程图一个流程或多个流程和/或方框图一个方框或多个方框中指定的功能。
