Claim 17:
18. A display system comprising:
a display processing device that controls display of an image;
a gyroscope sensor that detects a posture change amount in any one or more of a yaw direction, a pitch direction, a roll direction, a direction parallel to a roll axis, a direction parallel to a pitch axis, or a direction parallel to a yaw axis of a moving body, the posture change amount is caused by an angle change on a traveling path on which the moving body travels;
a correction processing device that sets a correction amount of a display position of the image based on the posture change amount by converting the posture change amount of the moving body into a number of pixels, and determines the correction amount that cancels the posture change amount indicated by the number of pixels;
a display determiner that determines not to display the image when an absolute value of the posture change amount or a variation amount in a predetermined unit time of the posture change amount is more than or equal to a predetermined threshold; and
an angle change detector that detects a change in an angle of a traveling path based on the posture change amount and the variation amount, wherein
the angle change detector
detects that a posture change of the moving body is started due to an angle change of the traveling path when the absolute value of the posture change amount is larger than a predetermined first threshold, and
detects that the posture change of the moving body is completed due to the angle change of the traveling path when the absolute value of the variation amount becomes smaller than a predetermined second threshold after start of the posture change of the moving body due to the angle change of the traveling path, and

the display determiner determines not to display the image during a period from a time when the start of the posture change is detected by the angle change detector to a time when completion of the posture change is detected, and
the display processing device controls display of the image based on a determination result of the display determiner and the correction amount.
