现在将参考附图更全面地描述示例实施方式。然而,示例实施方式能够以多种形式实施,且不应被理解为限于在此阐述的范例;相反,提供这些示例实施方式使得本申请的描述将更加全面和完整,并将示例实施方式的构思全面地传达给本领域的技术人员。附图仅为本申请的示意性图解,并非一定是按比例绘制。图中相同的附图标记表示相同或类似的部分,因而将省略对它们的重复描述。
以下结合本说明书的附图,对本申请的较佳实施方式予以进一步地详尽阐述。
在本申请首先提出一种外置闪光灯用于对其自身进行校色,校色可以是 指使外置闪光灯的实际发光参数与设定的发光参数匹配;还可以指调节外置闪光灯内每颗LED灯珠的发光参数一致性。发光参数可以包括亮度参数、色温参数、饱和度参数等。
请参阅图1和图2。在一实施例中,外置闪光灯10包括光源组件11、驱动电路12、控制电路13。光源组件11包括一个或多个LED光源。驱动电路12用于驱动光源组件11发光;控制电路13与驱动电路12电连接,且控制电路13供校色检测设备20电连接;其中,校色检测设备用于检测光源组件的发光信息。控制电路13用于从校色检测设备20接收光源组件11的发光信息,并根据发光信息进行校色处理后生成校色结果信息;驱动电路12根据校色结果信息驱动光源组件11的发光。
在此发光信息包括光亮度、色度、饱和度等中的一个或多种信息。在此可以以外置闪光灯10所发出的全部光线视为整体,采集其亮度、色度、饱和度中一种或多种参数。在另一实施例中,发光信息为闪光灯包括多颗LED光源中,每一颗LED光源的亮度、色度、饱和度等参数、色度以及饱和度中的一种或多种参数。即,在该实施例中,以每一颗LED光源为最小电路,来针对性地对每一颗LED进行发光校正,提高发光校正的准确性。在检测时,可以使每个LED光源单独发光,从而获取该LED光源的发光信息。
发光信息在此由校色检测设备20来采集,校色检测设备20可以包括拾色电路、数据转换电路、滤波电路等。根据所要校正的目标,拾色电路可以包括多种类型的光传感器;例如亮度传感器、色度传感器、色温传感器等校色检测设备的壳体上开设有采集窗口,该采集窗口面对外置闪光灯10的发光面设置,从而使拾色电路能够接收到外置闪光灯10所发出的光。在此,可以对外置闪光灯10所发出的光进行多次拾取。示意性的,使外置闪光灯10工作在多种发光模式下,均进行发光信息采样。发光模式在此有闪光模式、造型灯模式、常亮模式等。在每一个模式下,至少拾取一次发光信息。数据转换电路用于对采样到的发光信息的模拟量转换成相应的数字量。滤波电路用于对数据转换电路的输入或输出进行滤波,以降低噪声干扰。
校色检测设备20还可以包括数据排列电路,数据排列电路对所采集到的发光信息数据进行数据排列。具体数据排列的方式可以根据校色算法来确定,也可以按照外置闪光灯10中LED的位置排列来一一对应排列。在此中情况 下,控制电路13接收到的是发光信息排列数据。
另一示例中,数据排列电路也可以设置在控制电路13内,因此控制电路13接收到校色检测设备20所采集到的光源组件11所发出光的发光信息的数字量。
本申请中,外置闪光灯10的控制电路13能够接收校色检测设备20所检测的光源组件11的发光信息,并根据发光信息进行校色处理后生成校色结果信息;驱动电路12根据校色结果信息驱动光源组件11的发光。本申请方案实现对外置闪光灯10光源组件11的校色。
并且,本申请方案中,校色处理过程是在外置闪光灯10内完成,在完成校色得到校色结果信息后能够快速传输至驱动电路12,因此能够提高校色处理速度。且,由于校色处理相关的电路无需置于校色仪中,有利于实现校色仪的小型化,便于用户携带,以随时对外置闪光灯10进行校色。
控制电路13内包括有校色处理电路131,校色处理电路131内可以保存有校色处理算法,校色处理算法将上述已排列完成的发光数据进行逻辑计算,从而生产校色结果信息。该校色结果信息可以是调整程序,也可以是具体的发光矫正值。
示意性的,在一示例中,校色处理电路131包括校色芯片,校色芯片内置有校正系数矩阵,基于该校正系数矩阵对上述排列后的采样数据进行计算处理,以得到校色结果信息。
在另一示例中,通过将预设参数值与采样到的发光信息排列数据进行比对,以校正外置闪光灯10的驱动电流,以校正后的驱动电流驱动外置闪光灯10能够使闪光灯的实际发光参数正好匹配设定参数。
请继续参阅图1,控制电路13内还包括有发光控制电路132,发光控制电路132与驱动电路12电连接,以控制驱动电路12工作。在外置闪光灯10的正常工作过程中,由发光控制电路132生成控制信号控制闪光灯10的工作。
在一实施例中,在发光校正过程中,校色处理电路131供校色检测设备20电连接,以接收发光信息,并生成校色结果信息后发送至驱动电路12,以直接且实时校正光源组件11的发光。该实施例可以用于校色的调试过程。
在另一实施例中,校色处理电路131以及发光控制电路132电连接,校色处理电路131供校色检测设备20连接,以接收发光信息,并生成校色结果 信息。发光控制电路132与校色处理电路131电连接,以接收校色结果信息,发光控制电路132基于校色结果信息控制驱动电路12的工作。
示意性的,发光控制电路生成的发光信息可以为发光补偿值,通过将该发光补偿值发送至发光控制电路,以调节发光控制电路内发光参数与驱动电流的对应关系,例如亮度值-驱动电流的对应关系,从而调整驱动电路12所输出的驱动电流,进而实现对光源组件发光的校正。
在另一实施例中,发光控制电路132具有烧录端,烧录端与校色处理电路131电连接,烧录端接收校色结果信息,以调整发光控制电路132内的发光控制程序;驱动电路12与发光控制电路132电连接,以根据调整后的发光控制程序,驱动光源组件11的发光。
应当理解,烧录端的设置说明在校色处理电路131内具有烧录模块,烧录模块能够与发光控制电路132进行握手通讯,并满足相关通讯协议,以顺利进行程序烧写,调整原有的发光控制程序,调整对光源组件11的驱动电流,从而从根本上校正了外置闪光灯10的发光效果偏差问题。
图4是根据一示例性实施方式示出的一种外置闪光灯的校色系统的电路结构框图。在一实施例中,外置闪光灯10还具有无线通信电路15,无线通信电路15能够与校色检测设备20进行无线通讯,以通过无线传输方式接收校色检测设备20检测的发光信息,并将发光信息传输至控制电路13;具体可以是传输至校色处理电路131。
在此无线通讯电路15可以是内置于外置闪光灯10内,也可以外置于外置闪光灯10外,例如外置的USB无线发射器。无线通讯电路15可以是蓝牙模块、WIFI模块、Zig-Bee模块、广播模块等。应当理解,在外置闪光灯10内应设置与无线通讯电路15进行通讯连接的无线通讯模块。
该实施例提高了校色检测设备20与外置闪光灯10通讯的便利性,通过无线通讯电路15,能够免于在校色检测设备20以及外置闪光灯10上设置接口。更重要的是,无线通讯电路15可以允许校色检测设备20与外置闪光灯10之间的距离能够灵活的调节,从而可以基于不同的距离,采集到不同的发光信息,提高校正的准确性以及校正目标的灵活性。此处,校正目标可以设定为对外置闪光灯10在不同发光行程下发光参数的校正。
在另一实施例中,外置闪光灯10还具有通讯接口,通讯接口与控制电路 13电连接,且通讯接口用于与校色检测设备20通过连接线电连接,以接收校色检测设备20检测的发光信息。
在此,通讯接口具体可以为USB接口、TYPE C接口、RS232接口、RS485接口等其中的一种。在此,通讯接口可以有一个或多个。
图3是根据另一示例性实施方式示出的一种外置闪光灯的校色系统的电路结构框图。在一实施例中,控制电路13还包括时序控制电路14,时序控制电路14与驱动电路12电连接,以驱动光源组件11以预设时序发光;时序控制电路14还与校色检测设备20电连接,以在光源组件11以预设时序发光时,时序控制电路14控制校色检测设备20以预设的时序检测光源组件11的发光信息。
在此,时序控制电路14用于发出时序控制指令,时序控制指令可以包含有光源组件11的发光模式执行顺序、发光频率、亮度变化时序、色彩变化时序等。时序控制电路14也以预设的时序控制校色检测设备20采集光源组件11所发出的光,使得采集时序与发光时序具有同步性,从而能够确定所采集到的发光信息所对应的时序信息,提高校正的准确性。并且,该实施例允许校色检测设备20在外置闪光灯10不发光时,不进行数据采集,从而有利于降低校色检测设备20受到的噪声干扰,提高数据排列的精准性;且有利于节约能源。
在另一实施例中,在该实施例中,可以由校色检测设备20来发送时序控制命令,总控整个校色过程。具体的,时序控制电路14设置在校色检测设备20中。此时,控制电路13具有时序接收端,时序接收端可以通过无线通讯电路15或连接线接收时序控制信号;控制电路13根据时序控制信号控制驱动电路12工作,从而控制光源组件11以预设时序发光。
请参阅图5和图6,在一实施例中,校色检测设备20包括主体201以及凸伸出主体201一侧的拾光部202。具体的,主体201大致呈方形,主体内具有容置腔,以容纳一块或多块电路板,应当理解,本申请的相关电路可以部分或全部铺设于该电路板上。主体201的侧面还设有开关键205,当开关键205处于打开状态时,校色检测设备20启动,当开关键205处于关闭状态时,校色检测设备20关机。拾光部202位于主体的上侧。由于外置闪光灯10的光线辐射范围大致呈圆形,因此本申请设置拾光部202也大致呈圆形,以均 匀拾取外置闪光灯10发出的光线。本申请的校色检测设备20可以是手持式设备,以便利用户外出携带,以随时对外置闪光灯进行校色。
其中,主体201与拾光部202可以是可拆卸连接。具体可以是卡扣连接或在主体201上设置滑槽,在拾光部202上设置滑块,通过滑槽和滑块配合的方式连接。
