The information acquisition device acquires a position of a moving body and information outside the moving body. The display processing device controls display of an image based on information acquired by the information acquisition device. The posture detection device that detects posture variation of the moving body. The correction processing device that sets a correction amount of a display position of the image based on posture variation of the moving body, outputs the correction amount when the display information acquired from the display processing device indicates that the image is being displayed, and reduces size of the correction amount when the display information indicates that the image is not being displayed. ## Claims ### Claim 1 A display system comprising: an information acquisition device that acquires a position of a moving body and information outside the moving body; a display processing device that controls display of an image and outputs display information indicating whether or not the image is being displayed; a posture detection device that detects posture variation of the moving body; and a correction processing device that sets a correction amount of a display position of the image based on posture variation of the moving body, outputs the correction amount when the display information acquired from the display processing device indicates that the image is being displayed, and reduces size of the correction amount when the display information indicates that the image is not being displayed, wherein the display processing device controls a display position of the image based on a position of the moving body, the information outside the moving body, and the correction amount, and, wherein the correction processing device calculates the correction amount by subtracting a current displacement amount from a displacement amount when the image is not being displayed. ### Claim 2 (depends on 1) The display system according to claim 1, wherein the correction processing device resets the correction amount to zero when the display information indicates that the image is not being displayed. ### Claim 3 (depends on 1) The display system according to claim 1, wherein the correction processing device reduces size of the correction amount by a certain amount when the display information indicates that the image is not being displayed. ### Claim 4 (depends on 1) The display system according to claim 1, wherein when display information indicates that the image is not being displayed, the correction processing device reduces size of the correction amount by a certain amount in a case where the correction amount is equal to or more than a threshold value, and resets the correction amount to zero in a case where the correction amount is less than the threshold value. ### Claim 5 (depends on 1) The display system according to claim 1, wherein when the display information indicates that the image is being displayed, the correction processing device sets the correction amount based on posture variation of the moving body when the image is displayed and posture variation of the moving body before the image is displayed. ### Claim 6 (depends on 1) The display system according to claim 1, wherein the posture detection device includes at least one of a gyro sensor, an acceleration sensor, and a vehicle height sensor. ### Claim 7 A display system comprising: an information acquisition device that acquires a position of a moving body and information outside the moving body; a display processing device that controls display of an image and outputs display information indicating whether or not the image is being displayed; a posture detection device that detects posture variation of the moving body; and a correction processing device that calculates a displacement amount of a display position of the image due to posture variation of the moving body, and when the display information acquired from the display processing device indicates that the image is not being displayed, sets a reference position obtained by adding a displacement amount when the image is not being displayed based on posture variation of the moving body when the image is not displayed, sets a display position of the image based on the reference position and the displacement amount when the display information indicates the image is being displayed, and outputs position information of the display position, wherein the display processing device controls a display position of the image based on a position of the moving body, the information outside the moving body, and the position information. ### Claim 8 (depends on 1) The display system according to claim 1, further comprising a projection device that projects light representing the image. ### Claim 9 (depends on 1) The display system according to claim 1, wherein the moving body is a vehicle, and the image is a virtual image displayed in front of a windshield of a vehicle.
