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。
本申请首先提出一种校色检测设备，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。

在该实施例中，由终端设备30对采集到的发光信息进行排序处理，由于数据排序及处理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，能够提高数据排列速度及处理速度。更为重要的是，由于校色检测设备20内无需设置数据处理电路，因此可以减小校色检测设备20的体积，有利于提高校色检测设备20的便携性。
当然，在一些实施例中，校色处理电路可以包括上述数据排列电路。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。
