Abstract

A display device includes: a display means that displays a virtual image of a picture by projecting display light representing the picture on a windshield; an identification means that identifies a target outside the vehicle; a control means that causes a first captured image, visually recognized as being superposed on at least a part of the target, to be displayed in the picture; and a vibration detection means that detects the amount of vibration of the vehicle. The control means, when the amount of vibration detected by the vibration detection means exceeds a threshold value, causes a second captured image to be displayed instead of the first captured image. The second captured image is an image of which a color shade difference between pixels configuring an image end and a region outside the image and adjacent to the image end is decreased compared with the first captured image.

Claims

1. A display device mounted on a conveyance, the display device being for projecting display light showing video onto a light transmission member and therefore displaying a virtual image of the video while superposing the virtual image on scenery visually recognized through the light transmission member, the display device comprising:

display means for emitting the display light;

reflection means for reflecting the display light emitted by the display means toward the light transmission member;

identification means for identifying a predetermined target outside the conveyance;

control means for controlling the display means to display, in the video, a first capturing image to be visually recognized in a state in which the first capturing image is superposed on at least a part of the target identified by the identification means; and

vibration detection means for detecting an amount of vibration of the conveyance, wherein;

in the case where the amount of vibration detected by the vibration detection means exceeds a threshold value determined in advance, the control means displays, in the video, a second capturing image to be visually recognized in a state in which the second capturing image is superposed on at least a part of the target, instead of the first capturing image; and

the second capturing image is an image in which a color shade difference between pixels constituting an image end and a region outside the image and adjacent to the image end is reduced in comparison to the first capturing image.

2. The display device according to claim 1, wherein

the first capturing image is a frame image indicating a frame and is displayed so that at least a part of the target is positioned in the frame.

3. The display device according to claim 1, wherein

a color shade difference between adjacent pixels in a plurality of pixels constituting the second capturing image is smaller than a color shade difference between pixels constituting an image end of the first capturing image and a region outside the first capturing image and adjacent to the image end of the first capturing image.

4. The display device according to claim 2, wherein

a color shade difference between adjacent pixels in a plurality of pixels constituting the second capturing image is smaller than a color shade difference between the frame portion and a region in the frame in the first capturing image.

5. The display device according to claim 1, wherein

the second capturing image is a gradation image in which color is deeper from the image end toward a central portion.

6. The display device according to claim 2, wherein

a color shade difference between adjacent pixels in a plurality of pixels constituting the second capturing image is smaller than a color shade difference between pixels constituting an image end of the first capturing image and a region outside the first capturing image and adjacent to the image end of the first capturing image.

7. The display device according to claim 4, wherein

the second capturing image is a gradation image in which color is deeper from the image end toward a central portion.
