Abstract: A display system includes a display processing device that controls display of an image, a posture detection device that detects a posture change amount of a moving body, a correction processing device that sets a correction amount of a display position of the image, a display determiner that determines whether or not to display the image, and a gradient change detector that detects a gradient change of a traveling path. The gradient change detector detects that a posture change of the moving body is started when an absolute value of the posture change amount is larger than a first threshold, and that the posture change is completed when the absolute value becomes smaller than a second threshold after start of the posture change. The display determiner determines not to display the image from start of the posture change until completion of the posture change.

Abstract: A display system includes an information acquisition device that acquires a position of a moving body, a display processing device that controls display of an image based on information acquired by the information acquisition device, a posture detection device that detects a posture variation of the moving body, a correction processing device that sets a first correction amount based on the posture variation, a gradient correction processing device that sets a second correction amount based on gradient information and a superimposition destination position at which the image is superimposed on an actual view in a display direction of the image, and a correction overlap amount setting unit that sets a correction overlap amount by which the first correction amount and the second correction amount overlap. The display processing device controls display of the image based on the first correction amount, the second correction amount, and the correction overlap amount.

Abstract: The present disclosure provides a display system that displays an image in front of a windshield of a moving body. The display system includes a projection device, an information acquisition device that acquires speed information of the moving body, a detection device that detects posture variation of the moving body, a display processing device that controls a display position of the image based on a reference position and a correction amount, and a correction processing device that sets the correction amount based on posture variation of the moving body. The correction processing device adjusts the correction amount to a value equal to or less than a correction amount immediately before a speed of the moving body becomes equal to or less than the first threshold in a case of determining that the speed of the moving body is equal to or less than the first threshold.

Abstract: The present disclosure provides a display system that detects a first posture variation of a moving body having a first axis as a rotation axis, a display processing device that controls a display position of an image based on a reference position and a correction amount, and a correction processing device that sets the correction amount based on magnitude of the first posture variation. The detection device detects a second posture variation of the moving body having a second axis orthogonal to the first axis as a rotation axis. The correction processing device corrects interference of the second posture variation with respect to magnitude of the first posture variation based on magnitude of the second posture variation in setting of the correction amount.
