PROBLEM TO BE SOLVED: To perform color calibration of a video signal outputted from a color camera into an optional color with a small and simple configuration. SOLUTION: A color camera calibration system to be disclosed is provided with a reference light generating device 1 for generating synthetic reference light L<SB>RGB</SB>obtained by synthesizing red reference light, green reference light and blue reference light emitted from a red light emitting LED 11, a green light emitting LED 12 and a blue LED 13 respectively, a correction coefficient calculation circuit 3 for calculating a correction coefficient for color calibration on the basis of respective light emission wavelength data D<SB>R</SB>, D<SB>G</SB>and D<SB>B</SB>of the red LED 11, the green LED 12 and the blue LED 13, optional color setting data D<SB>C</SB>and a video signal S<SB>P</SB>supplied from the color camera 2, and a color correction circuit 5 for performing color calibration of the video signal S<SB>P</SB>on the basis of the correction coefficient.
