Abstract

A composite display device is provided with an optical combiner, a first display unit which displays a virtual image by projecting an image including certain display information to a front surface of the optical combiner, a second display unit which is disposed on a position of a rear surface side of the optical combiner and displays a real image, and a composite display control unit.

First claim

What is claimed is:

1. A composite display device comprising:
an optical combiner that includes a front surface and a rear surface, and reflects and transmits light that is incident on the front surface;
a first display device configured to project a first display image including certain display information to the front surface of the optical combiner, such that the first display image is displayed by the combiner as a virtual image;
a second display device that is disposed adjacent to the rear surface of the optical combiner and configured to display a second display image as a real image; and
a composite display control device configured to
concurrently instruct the first display device to project the first display image and the second display device to display the second display image such that the virtual image has a shape that is the same as or similar to a shape of the real image, and
instruct one of the first display device and the second display device to display a respective one of the first display image and the second display image in a position such that the virtual image at least partially overlaps the real image, and such that the virtual image is displaced relative to the real image in a direction orthogonal to a gaze axis of an observer, thereby forming a parallax between the virtual image and the real image.

2. The composite display device according to claim 1 , wherein the composite display control device is further configured to determine a difference in display pattern size between the first display image and the second display image.

3. The composite display device according to claim 1 , wherein the composite display control device is further configured to determine a difference in display brightness between the first display image and the second display image.

4. The composite display device according to claim 1 , further comprising:
a third display device that is disposed in a position different from the first display device and the second display device, wherein
when displaying an image of at least one of the first display device and the second display device, the composite display control device instructs the third display device to display information on the third display device which is relevant to the image displayed by the at least one of the first display device and the second display device.

5. The composite display device according to claim 1 , wherein the optical combiner is located between the first display device and the second display device.
