Abstract

A display device includes an image generator configured to generate a service image to be visually recognized by an observer by outputting light for forming an image toward a reflector reflecting incident light toward the observer's eyes and superimposing the light on a scene, a receiver configured to receive the observer's operation of reducing a visibility of the image, and a controller configured to control a visibility of the service image in accordance with the operation performed on the receiver, and the controller is configured to cause the image generator to generate a warning image in a case in which the operation of reducing the visibility to a predetermined degree is performed.

First claim

What is claimed is:

1. A display device comprising:
an image generator configured to generate a service image to be visually recognized by an observer by outputting light for forming an image toward a reflector reflecting incident light toward the observer's eyes and superimposing the light on a scene;
a receiver configured to receive the observer's operation of reducing a visibility of the image; and
a controller configured to control a visibility of the service image in accordance with the operation performed on the receiver,
wherein the controller is configured to cause the image generator to generate a warning image in a case in which the operation of reducing the visibility to a predetermined degree is performed,
the operation includes an operation of increasing a depression angle at a position where the service image is visually recognized by the observer and an operation of reducing a luminance of the service image, and
the controller is further configured to increase the depression angle at the position where the service image is visually recognized by the observer in accordance with the operation in a case in which the depression angle is less than a maximum depression angle, reduce the luminance of the service image in accordance with the operation in a case in which the depression angle is the maximum depression angle, and cause the image generator to output the warning image in a case in which a magnitude of the luminance has reached a threshold value.

2. The display device according to claim 1 , wherein the warning image is an image including information for inquiring whether to generate the service image.

3. A display device comprising:
an image generator configured to generate a service image to be visually recognized by an observer by outputting light for forming an image toward a reflector reflection incident light toward the observer's eyes and superimposing the light on a scene;
a receiver configured to receive the observer's operation of reducing a visibility of the image; and
a controller configured to control a visibility of the service image in accordance with the operation performed on the receiver,
wherein the controller is configured to cause the image generator to generate a warning image in a case in which the operation of reducing the visibility to a predetermined degree is performed,
the operation includes an operation of increasing a depression angle at a position where the service image is visually recognized by the observer and an operation of reducing a size of the service image, and
the controller is configured to increase the depression angle at the position where the service image is visually recognized by the observer in accordance with the operation in a case in which the depression angle is less than a maximum depression angle, reduce the size of the service image in accordance with the operation in a case in which the depression angle is the maximum depression angle, and cause the image generator to output the warning image in a case in which the size has reached a threshold value.

4. The display device according to claim 3 , wherein the warning image is an image including information for inquiring whether to generate the service image.

5. A display device comprising:
an image generator configured to generate a service image to be visually recognized by an observer by outputting light for forming an image toward a reflector reflecting incident light toward the observer's eyes and superimposing the light on a scene;
a receiver configured to receive the observer's operation of reducing a visibility of the image; and
a controller configured to control a visibility of the service image in accordance with the operation performed on the receiver,
wherein the controller is configured to cause the image generator to generate a warning image in a case in which the operation of reducing the visibility to a predetermined degree is performed,
the operation includes an operation of reducing a luminance of the service image and an operation of reducing a size of the service image, and
the controller is configured to reduce the luminance of the service image in a case in which the luminance is less than a minimum luminance, reduce the size of the service image in accordance with the operation in a case in which the luminance has a minimum value, and cause the image generator to output the warning image in a case in which the size has reached a threshold value.

6. The display device according to claim 5 , wherein the warning image is an image including information for inquiring whether to generate the service image.
