Abstract

A processing apparatus includes a distance image acquirer, a moving-object detector, and a danger-level determining unit. The distance image acquirer acquires a distance image containing distance information of each pixel. The moving-object detector detects a moving object from the distance image. The danger-level determining unit determines a danger level of the moving object by use of the distance image, and outputs the danger level to a controller that controls a controlled unit in accordance with the danger level.

First claim

What is claimed is:

1. A display device, comprising:
processing circuitry configured to detect, from images obtained by imaging a range including a field of vision of an observer, a motion vector of an object included in the images, the motion vector indicating a direction of movement and a speed of movement of the object; and
a display to perform display based on the detected motion vector, wherein
the processing circuitry is further configured to determine a display image to display, based on the direction and the speed of the object, as indicated y the motion vector, and cause the display to display the determined display image in a superimposed manner on the field of vision of the observer.

2. The display device according to claim 1 , wherein the processing circuitry is further configured to determine a danger level of the object based on the direction and speed of the object, as indicated by the motion vector, and
cause the display to perform the display in accordance with the determined danger level.

3. The display device according to claim 2 , wherein the processing circuitry is further configured to change a method of determining the danger level of the object in accordance with a recognition result of the object obtained from processing the images.

4. The display device according to claim 3 , wherein the processing circuitry is further configured to change a threshold used in assigning the danger level, in accordance with the recognition result.

5. The display device according to claim 2 , wherein the processing circuitry is further configured to cause the display to perform the display in a color according to the danger level.

6. The display device according to claim 1 , wherein the display is a headup display.

7. The display device according to claim 6 , wherein the headup display is a laser-scanning-type headup display.

8. The display device according to claim 1 , wherein the processing circuitry is further configured to cause the display to perform the display in such a manner to superimpose, as the display image, a solid filled part on the field of vision of the observer.

9. The display device according to claim 8 , wherein the display of the solid filled part is a gradation display that density thereof gradually changes.

10. The display device according to claim 1 , wherein the processing circuitry is further configured to cause the display to perform the display in such a manner to superimpose, as the display image, a line on the field of vision of the observer.

11. The display device according to claim 1 , wherein the processing circuitry is further configured to cause the display to perform the display, which changes along a traveling direction of the object.

12. The display device according to claim 11 , wherein the processing circuitry is further configured to cause the display to perform the display such that luminance levels change along a traveling direction of the object.

13. The display device according to claim 1 , wherein the processing circuitry is further configured to cause the display to display information of a predicted motion of the object.

14. The display device according to claim 13 , wherein the processing circuitry is further configured to cause the display to perform the display based on a group of motion vectors that predict the motion of the object.

15. The display device according to claim 14 , wherein the processing circuitry is further configured to cause the display to perform the display based on a normal-line group of the group of motion vectors.

16. The display device according to claim 13 , wherein the display displays an animated image as the information of the predicted motion of the object.

17. The display device according to claim 1 , wherein
the display is mounted in a vehicle, and
the processing circuitry is further configured to cause the display to display a moving route of the object positioned behind the vehicle in a traveling direction of the vehicle.

18. A vehicle comprising the display device according to claim 1 .

19. A vehicle comprising the display device according to claim 2 , wherein the vehicle controls the vehicle in accordance with the determined danger level.

20. A display method, comprising:
detecting, from images obtained by imaging a range including a field of vision of an observer, a motion vector of an object included in the images, the motion vector indicating a direction of movement and a speed of movement of the object; and
determining a display image to display, based on the direction and the speed of the object, as indicated by the motion vector;
displaying the determined display image in a superimposed manner on the field of vision of the observer.
