The display device is configured to provide a display on a window of a vehicle. The position acquiring unit is configured to acquire a position of a target person present outside the vehicle. The display controller is configured to control the display device to invert the display to be provided for the target person, on the basis of the position of the target person. ## Claims ### Claim 1 A vehicle display system comprising: a display device configured to display on a window of a vehicle a first image and a second image which is an inverted image of the first image; a position acquiring unit configured to acquire a position of a target person present outside the vehicle; and a display controller configured to control the display device to alternately display the first image and the second image on the window based on the position of the target person, wherein the display controller stops displaying the one of the first image and the second image based on determining that the target person is aware of the vehicle. ### Claim 2 (depends on 1) The vehicle display system according to claim 1, wherein when the first image and the second image are texts, the first image is for the target person and the second image is for an occupant inside the vehicle, and when the first image and the second image are symbols, the first image is a positive image and the second image is a negative image. ### Claim 3 (depends on 1) The vehicle display system according to claim 1, wherein when a distance from the vehicle to the target person is equal to or greater than a first threshold, the display controller controls the display device to alternately display the first image and the second image on the window. ### Claim 4 (depends on 2) The vehicle display system according to claim 2, wherein when a distance from the vehicle to the target person is equal to or greater than a first threshold, the display controller controls the display device to alternately display the first image and the second image on the window. ### Claim 5 (depends on 3) The vehicle display system according to claim 3, wherein the display controller controls the display device to alternately display the first image and the second image on the window and then controls the display device to display one of the first and second images on the window for the target person. ### Claim 6 (depends on 4) The vehicle display system according to claim 4, wherein the display controller controls the display device to alternately display the first image and the second image on the window and then controls the display device to display one of the first and second images on the window for the target person. ### Claim 7 (depends on 5) The vehicle display system according to claim 5, wherein the display controller stops displaying the one of the first image and the second image based further on determining that the distance from the vehicle to the target person is equal to or greater than a predetermined second threshold. ### Claim 8 (depends on 6) The vehicle display system according to claim 6, wherein the display controller stops displaying the one of the first image and the second image based further on determining that the distance from the vehicle to the target person is equal to or greater than a predetermined second threshold. ### Claim 9 (depends on 7) The vehicle display system according to claim 7, further comprising a warning sound generator configured to make a warning sound, when the target person is not aware of the vehicle. ### Claim 10 (depends on 8) The vehicle display system according to claim 8, further comprising a warning sound generator configured to make a warning sound, when the target person is not aware of the vehicle. ### Claim 11 A method of controlling a vehicle display system displaying an image on a window of a vehicle, the method comprising: acquiring a position of a target person present outside a vehicle; alternately displaying a first image and a second image on the window based on the position of the target person, the second image being an inverted image of the first image; and stopping displaying the one of the first image and the second image based on determining that the target person is aware of the vehicle. ### Claim 12 A vehicle display system comprising: a display device configured to display on a window of a vehicle a first image and a second image which is an inverted image of the first image; and circuitry configured to acquire a position of a target person present outside the vehicle, control the display device to alternately display the first image and the second image on the window based on the position of the target person, and control the display device to stop displaying the one of the first image and the second image based on determining that 1) the target person is aware of the vehicle and 2) a distance between the position of the target person and a position of the vehicle is equal to or greater than a threshold.
