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.

First claim

The invention claimed is:

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.
