PROBLEM TO BE SOLVED: To perform color conversion corresponding to the type of a monitor to be connected and to display an image of the same color characteristic on a plurality of monitors. SOLUTION: An endoscopic image signal inputted to a color conversion device 11 is inputted to 1st, 2nd and 3rd color converting parts 13, 14 and 15 without being attenuated due to the amplification by a signal amplifier 12, color conversion is performed by the 1st to 3rd color converting parts 13 to 15, and conversion parameters of the 1st to 3rd color converting parts 13 to 15 where image signals subjected to color conversion are supplied to a main monitor 6, a nurse monitor 7 and a patient monitor 10 are decided and changed in a conversion matrix producing part 16 on the basis of the endoscopic image signal amplified by the amplifier 12. |
