Claim 0:
1. A display system comprising:
a display processing device that controls display of an image;
a gyroscope sensor that detects a posture change amount in a pitch direction of a moving body, the posture change amount is caused by a gradient 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 whether or not to display the image; and
a gradient change detector that detects a gradient change of the traveling path based on the posture change amount and a variation amount in a predetermined unit time of the posture change amount, wherein.
the gradient change detector
detects that a posture change of the moving body is started due to the gradient change of the traveling path when an absolute value of the posture change amount in the pitch direction of the moving body becomes larger than a predetermined first threshold, and
detects that the posture change of the moving body is completed due to the gradient change of the traveling path when the absolute value of the variation amount in the pitch direction becomes smaller than a predetermined second threshold after start of the posture change of the moving body due to the gradient 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 gradient 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.
