背景技术
随着移动通讯技术的发展，移动终端在人们的生活和工作中发挥着越来越重要的作用。特别是一些具有照相功能的移动终端设备，例如手机、MP4、PDA、笔记本电脑等，这些移动终端所具有的照相功能给人们的生活带来了极大的乐趣。拍照需要光源，除了自然光外更多的时候需要人造光来辅助拍照，带照相功能的移动终端自带的人造光源往往满足不了实际使用需求，为此，人们常会利用外置闪光灯来进行辅助拍摄。
然而，外置闪光灯中的LED灯珠在长久使用后，存在色度与发光强度的偏差，导致实际的发光亮度、色度等发光参数无法达到预设的发光参数，从而无法达到预期的补光效果。

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校色设备，校色设备用于对外置闪光灯进行校色，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，校色设备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201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，校色设备20启动，当开关键205处于关闭状态时，校色设备20关机。拾光部202位于主体201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。
图3是根据一示例实施方式示出的一种校色设备的电路结构框图。在一实施例中，校色设备20包括发光信息采集电路21、第一通讯电路23、校色 处理电路22。发光信息采集电路21用于检测外置闪光灯10的发光信息；第一通讯电路23用于与终端设备30通讯，以接收终端设备30发送的校色控制指令；校色处理电路22与发光信息采集电路21，以及第一通讯电路23均电连接，校色处理电路22接收第一通讯电路23所传输的校色控制指令后，基于发光信息进行校色处理，生成校色结果信息；校色结果信息用于传输至外置闪光灯10，以校正外置闪光灯10的发光。
校色设备20还可以包括壳体，发光信息采集电路21、校色处理电路22、通讯电路23均集成于壳体内。本申请的校色设备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10进行校色。
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为一整体来看待，来采集其亮度、色度、饱和度等参数。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。
发光信息采集电路21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。壳体上一般具有采集窗口。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。
校色处理电路22可以包括数据排列电路和数据处理电路。数据排列电路与模数转换电路连接，以对所采集到的发光信息的数字量进行数据排列。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。
数据处理电路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，数据处理电路包括校色芯片，校色芯片中具有校正系数矩阵，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。
还可以是，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。
校色设备20的第一通讯电路23用于与终端设备30通讯。第一通讯电路23可以为无线通讯电路；在此无线通讯电路可以是内置于校色设备20内，也可以外置于校色设备20外，例如外置的USB无线发射器。第一通讯电路23可以为无线通讯电路；无线通讯电路包括WIFI模块、蓝牙模块、或Zig-Bee模块、红外通讯模块中的一种或多种。该实施例提高了校色设备20与终端设备30通讯的便利性，通过无线通讯电路，能够免于在校色设备20和终端设备30上设置接口。
在另一实施例中，第一通讯电路23包括通讯接口；其中，通讯接口为USB接口、TYPE C接口、RS232接口、RS485接口中的一种。在此，通讯接口可以有一个或多个。
在本实施例中，终端设备30可以是智能终端、例如手机、平板、笔记本电脑；还可以是智能穿戴设备，例如智能头戴设备、智能手环、智能腰带等。终端设备30在当今工作生活中较广泛的被使用，本申请方案通过将校色设备20与终端设备30结合，从而有利于减小校色设备20的体积，便于用户携带。
在一实施例中，终端设备30包括显示单元，显示单元用于显示GUI(Graphical User Interface，图形用户接口)界面，以供输入校色控制指令。具体的，在终端设备30内安装校色应用软件，当运行校色应用软件时，可以在显示屏上显示校色控制界面。该校色控制界面具有多个控件用于供用户发出校色启动指令，以及设定校色参数、校色模式选择(在此统称为校色控制指令)等。该校色控制界面还可以具有显示窗口，以显示校色进程。该实施例提高了校色设备20的智能化，提高了人机交互能力，便于用户根据自己的需求来对外置闪光灯10不同的参数(亮度、色度、饱和度等)进行校正，以 及校正至符合自己要求的目标参数。
智能终端接收到用户发送的校色控制指令后，将该指令通过第一通讯电路23传输至校色处理电路22，以使校色处理电路22按照校色控制指令对外置闪光灯10的发光信息进行校色处理，从而生成相应的校色结果信息。
本申请方案通过设置第一通讯电路23，用于与终端设备30通讯，以接收终端设备30发送的校色控制指令。校色处理电路22接收第一通讯电路23所传输的校色控制指令后，基于采集到的发光信息进行校色处理，生成校色结果信息；校色结果信息用于传输至外置闪光灯10，以校正外置闪光灯10的发光。由此，本实施例实现了对外置闪光灯10的发光校正。
图4是根据一示例实施方式示出的一种校色设备与终端设备的电路连接框图。在另一实施例中，校色设备20还包括第二通讯电路25，第二通讯电路25用于发送外置闪光灯10的发光信息至终端设备30；其中，终端设备30用于将发光信息处理成发光信息的排序数据；第一通讯电路23用于接收发光信息的排序数据，并发送至校色处理电路22。
在该实施例中，可以将数据排序电路设置在终端设备30中。由于数据排序需要较快的运行速度以及存储容量，因此利用终端设备30强大的处理器以及大存储容量，能够提高数据排序速度。更为重要的是，由于校色设备20内无需设置排序电路，因此可以减小校色设备20的体积，有利于提高校色设备20的便携性。
进一步的，还可以将上述提到的数据转换电路、滤波电路的功能均由终端设备30来完成，由此可以进一步减小校色设备20的体积。此时校色设备20的发光信息采集电路21将采集到的发光信息模拟量直接传输至终端设备30，由终端设备30进行数据转换、滤波、排序等数据处理。
在此，第二通讯电路25可以与第一通讯电路23是同一个，也可以是彼此独立的。同样的，第二通讯电路25也可以为无线通讯电路，也可以是通讯接口。
图5是根据另一示例实施方式示出的一种校色设备与终端设备的电路连接框图。在一实施例中，校色设备20还包括存储电路26，存储电路26用于保存多次检测的发光信息；存储电路26与第二通讯电路25电连接，以通过第二通讯电路25将发光信息发送至终端设备30。存储电路26可以是ROM 或RAM等，也可以是存储介质，例如U盘。
该实施例实现了可以利用校色设备20采集多组发光信息，并存储，之后在条件允许的情况下，使校色设备20与终端设备30建立通讯连接，实现对发光信息的校色处理。处理完成后的校色结果信息也可以存储在该存储电路26中，以在合适的时机传输至外部闪光灯中，实现最终的校正过程。该实施例提高了校色的便利性。
在一实施例中，发光信息采集电路21还包括时序接收端，时序接收端用于与终端设备30连接，以接收终端设备30发送的时序控制指令；发光信息采集电路21根据时序控制指令，对外置闪光灯10进行发光信息采集。
时序接收端与终端设备30可以是直接连接，也可以是间接连接，在此不做限定。时序控制指令用于控制外置闪光灯10以预设时序进行发光，并控制发光信息采集电路21相应以预设的时序采集发光信息。
在此，时序控制指令可以包含有外置闪光灯10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。时序控制指令也以预设的时序控制发光信息采集电路21采集外置闪光灯10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，该实施例允许发光信息采集电路21在外置闪光灯10不发光时，不进行数据采集，从而有利于降低发光信息采集电路21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，校色设备20还包括时序控制电路，时序控制电路与终端设备30以及外置闪光灯10、发光信息采集电路21均电连接；时序控制电路根据校色控制指令发出时序信号至外置闪光灯10以及发光信息采集电路21，以使外置闪光灯10以预设时序进行发光，并使发光信息采集电路21以预设的时序采集发光信息。

当然，第三通讯电路24还可以是通讯接口，例如USB接口、TYPE C接 口、RS232接口、RS485接口中的一种，以通过连接线与外置闪光灯10，实现数据和信号的交互。
在一实施例中，外置闪光灯10内包括有控制芯片、驱动电路以及光源电路。控制芯片发出控制信号至驱动电路，驱动电路进而驱动光源电路发光。在一实施例中，校色处理电路22通过通讯电路将校色结果信息发送给外置闪光灯10的控制芯片或驱动电路，以直接校正光源电路的发光。该实施例可以用于校正的调试过程。
在另一实施例中，校色设备20还包括烧录电路，烧录电路与校色处理电路22电连接，且供外置闪光灯10电连接，以用于将校色处理电路22输出的校色结果信息烧录至外置闪光灯10的控制芯片内。在该实施例中，烧录电路能够与控制芯片进行握手通讯，并满足相关通讯协议，以顺利进行程序烧写，从而从根本上校正了外置闪光灯10的发光效果偏差问题。
在此烧录电路与校色处理电路22可以直接电连接或间接电连接。烧录电路可以内置于校色设备20的壳体内；也可以外置于校色设备20的壳体外，而形成一独立的模块。
