Color correction device, and color correction system having external flash

A color correction system comprising an external flash, a terminal device and a color correction device, wherein color correction device, comprises:

• a light-emission information collection circuit configured to collect light-emission information of the external flash;
• a first communication circuit configured to communicate with the terminal device, so as to receive a color correction control instruction sent by the terminal device;
• and
• a color correction processing circuit electrically connected to the light-emission information collection circuit and the first communication circuit, wherein the color correction processing circuit receives the color correction control instruction transmitted by the first communication circuit and then performs color correction processing on the basis of the light-emission information to generate the color correction result information, and the color correction result information is configured to be transmitted to the external flash so as to correct light-emission of the external flash;
• wherein the color correction device is configured to detect the light-emission information of the external flash and processing the light-emission information under the control of the terminal device to generate the color correction result information, and wherein the external flash corrects the light-emission according to the color correction result information.
