A motion calibration using close loop PID control and a correction method thereof are provided to PID-operate two color information and one brightness information by a close loop controller to correct the values on a monitor, and feed back estimation error between an estimation value obtained by estimating color information and brightness information of a color of the corrected monitor and a preset setting value to each close loop PID controller, thereby reducing the correction error and obtaining standardized color and accurate contrast by repeating the above process until obtaining colors close to the setting value. A close loop PID controller receiving two color information and a close loop PID controller receiving brightness information are in monitor calibration correcting color information that a monitor outputs by receiving color information. Color of the monitor is corrected by the PID operating value from each close loop PID controller, estimation error between an estimation value obtained from the monitor and a preset setting value is fed back to each close loop PID controller.
