Color correction detection apparatus and color correction system having external flash

A color correction system, comprising an external flash, a color correction detection device, a terminal device, and a color correction processing apparatus;

• wherein the color correction processing apparatus comprises:
• a first communication circuit configured to receive digital quantity data of light-emission information of the external flash;
• a color correction processing circuit electrically connected to the first communication circuit, so as to receive the digital quantity data of the light-emission information by means of the first communication circuit, and to carry out color correction processing according to the digital quantity data of the light-emission information to generate color correction result information;
• a second communication circuit configured to be electrically connected to the external flash, the second communication circuit being electrically connected to the color correction processing circuit to transmit the color correction result information to the external flash, so as to correct light emission of the external flash;
• and
• a display screen configured to display a color correction control interface for inputting a color correction control instruction;
• wherein the color correction detection device is configured to detect the light-emission information of the external flash and send the light-emission information to the terminal device, wherein the terminal device processes the light-emission information to obtain the digital quantity data of light-emission information and sends the digital quantity data of the light-emission information to the color correction processing apparatus, and wherein the color correction processing apparatus generates the color correction result information according to the digital quantity data of the light-emission information and sends the color correction result information to the external flash, and the external flash corrects light emission according to the color correction result information.
