A display system includes an attitude detection device configured to detect an attitude change amount of a moving body, and a correction processing device including a vibration detector configured to determine whether or not an attitude change in the moving body having a specific frequency band component has been continuously generated based on the attitude change amount. The correction processing device updates a correction amount of a display position of the image based on the attitude change amount when the vibration detector determines that the attitude change having the specific frequency band component has not been continuously generated, and sets an absolute value of the correction amount to be equal to or less than an absolute value of a correction amount at a time of last determination when the vibration detector determines that the attitude change having the specific frequency band component has been continuously generated.
