Abstract

Disclosed is a display device including a passenger image capture unit configured to capture information of a passenger who is riding in a vehicle together with a driver of the vehicle; an image generator configured to generate an image that shows a condition of the passenger based on the information that is captured by the passenger image capture unit; and an image display unit configured to superimpose the image with a visual field of the driver, and configured to display the image in the visual field of the driver.

Claims

1. A display device comprising:

a passenger image capture unit configured to capture information of a passenger who is riding in a vehicle together with a driver of the vehicle;

an image generator configured to generate an image that shows a condition of the passenger based on the information that is captured by the passenger image capture unit;

an image display unit configured to superimpose the image with a visual field of the driver, and configured to display the image in the visual field of the driver; and

a passenger condition detector configured to detect the condition of the passenger,

wherein the image generator is configured to generate the image based on the information captured by the passenger image capture unit and information that is obtained from the passenger condition detector.

2. The display device according to claim 1,

wherein the passenger condition detector is configured to detect the condition of the passenger based on the information that is captured by the passenger image capture unit.

3. The display device according to claim 1,

wherein the image includes text that is generated based on the information that is obtained from the passenger condition detector.

4. The display device according to claim 1, further comprising:

a driver image capture unit configured to capture information of the driver; and

a driver'"'"'s line-of-sight detector configured to detect a direction of a line of sight of the driver based on the information that is captured by the driver image capture unit,

wherein the display device is configured to determine whether the image is to be displayed, based on a change in the direction of the line of sight of the driver.

5. The display device according to claim 4,

wherein the display device is configured to display the image at a position in consideration of the direction of the line of sight of the driver.

6. The display device according to claim 4,

wherein the passenger image capture unit has an angle of view that is wider than that of the driver image capture unit.

7. The display device according to claim 6,

wherein the passenger is in a rear seat of the vehicle, and

wherein the passenger image capture unit is configured to capture an image of a whole of the rear seat that includes the passenger.

8. The display device according to claim 4, further comprising:

a passenger display,

wherein the display device is configured to display an image that is captured by the driver image capture unit on the passenger display.

9. The display device according to claim 1,

wherein the image display unit is configured not to display the image that is superimposed with the visual field of the driver under a predetermined condition.

10. The display device according to claim 9,

wherein, when the direction of the line of sight of the driver is moving in a complicated manner, or when the direction of the line of sight of the driver is moving extensively, the image display unit is configured not to display the image that is superimposed with the visual field of the driver.

11. The display device according to claim 10, further comprising:

a distance measurement unit configured to measure a distance between the vehicle and another vehicle in front of the vehicle,

wherein, in response to determining that the distance is short from a distance measurement result by the distance measurement unit, the image display unit is configured to avoid displaying the image that is superimposed with the visual field of the driver.

12. The display device according to claim 1,

wherein the image display unit includes a laser light source, and an optical deflector configured to deflect a laser light beam that is emitted from the laser light source.

13. (canceled)

14. A vehicle comprising:

a display device; and

a seat,

wherein the display device includes

a passenger image capture unit configured to capture information of a passenger who is riding in a vehicle together with a driver of the vehicle;

an image generator configured to generate an image that shows a condition of the passenger based on the information that is captured by the passenger image capture unit;

an image display unit configured to superimpose the image with a visual field of the driver, and configured to display the image in the visual field of the driver; and

a passenger condition detector configured to detect the condition of the passenger,

wherein the image generator is configured to generate the image based on the information captured by the passenger image capture unit and information that is obtained from the passenger condition detector.
