Vehicle display system and method of controlling vehicle display system

1. A vehicle display system comprising:

a display device mounted on a vehicle;

a backward movement determiner configured to determine whether the vehicle moves backward;

a determiner configured to determine, when the vehicle moves backward, whether a person present outside the vehicle enters a blind spot of a driver of the vehicle, the blind spot being in a rear side of the vehicle; and

a display controller configured to control, when the person enters the rear blind spot, the display device to display a first warning on a rear window of the vehicle, the first warning being displayed towards the person outside the vehicle.

2. The vehicle display system according to claim 1 , wherein, when the person enters the blind spot, the display controller controls the display device to inform the person of an entry into the blind spot.

3. The vehicle display system according to claim 2 , wherein the display controller controls the display device to display, on the rear window, one or both of a back guide and a message, the message indicating that the person comes close to the vehicle.

4. The vehicle display system according to claim 1 , wherein, when the person enters the blind spot, the display controller controls the display device to display a second warning to the driver, the second warning being different from the first warning.

5. The vehicle display system according to claim 4 , wherein the display controller controls the display device to display, on the rear window, one or both of a back guide and a message, the message indicating that the person comes close to the vehicle.

6. The vehicle display system according to claim 1 , wherein the display controller controls the display device to display, on the rear window, one or both of a back guide and a message, the message indicating that the person comes close to the vehicle.

7. The vehicle display system according to claim 1 , wherein the display controller is further configured to control, when the person enters the blind spot, the display device to display, on the rear window of the vehicle, an arrow indicating that the person is present at the blind spot and a location of the person.

8. A method of controlling a vehicle display system, the method comprising:

determining whether a vehicle moves backward;

determining, when the vehicle moves backward, whether a person present outside the vehicle enters a blind spot of a driver of the vehicle, the blind spot being in a rear side of the vehicle; and

controlling, when the person enters the blind spot, a display device of the vehicle to display a warning on a rear window of the vehicle, the warning being displayed towards the person outside the vehicle.

9. The method according to claim 8 , further comprising:

controlling, when the person enters the blind spot, the display device to display, on the rear window of the vehicle, an arrow indicating that the person is present at the blind spot and a location of the person.

a display device mounted on a vehicle; and

circuitry configured to

determine whether the vehicle moves backward,

determine, when the vehicle moves backward, whether a person present outside the vehicle enters a blind spot of a driver of the vehicle, the blind spot being in a rear side of the vehicle, and

control, when the person enters the blind spot, the display device to display a warning on, a rear window of the vehicle, the warning being displayed towards the person outside the vehicle.

11. The vehicle display system according to claim 10 , wherein the circuitry is further configured to configured to control, when the person enters the blind spot, the display device to display, on the rear window of the vehicle, an arrow indicating that the person is present at the blind spot and a location of the person.
