Abstract

A display apparatus includes: a glass-type frame mounted to a head of an observer; and two image displaying devices for the left and right eyes that are attached to the frame. Each of the image displaying devices includes an image forming device, an optical system making light from the image forming device to be parallel light, and an optical device to which the light from the optical system is incident, and in which the light is guided so as to be output, at least one of the image displaying devices further includes a movement device relatively moving optical axes of the image forming device and the optical system in a horizontal direction, and a convergence angle is adjusted by relatively moving the optical axes of the image forming device and the optical system in the horizontal direction using the movement device depending on an observation position of an observer.

Claims

1. A display apparatus comprising:

a glass-type frame configured to be mounted to a head of an observer;

an image displaying device attached to the glass-type frame, the image displaying device comprising;

an image forming device,

an optical system, and

a movement device responsive to a control signal to move an optical axis of the image forming device and an optical axis of the optical system in a horizontal direction to adjust a convergence angle of a virtual image provided by the image forming device; and

a control device configured to provide the control signal to the movement device to adjust the convergence angle of the virtual image based on observation position information of the observer, wherein the observation position information of the observer permits adjustment of the convergence angle of the virtual image provided by the image forming device relative to a convergence angle of an observation target.

2. The display apparatus according to claim 1, wherein observation position information regarding the observation position of the observer is given to the display apparatus in advance.

3. The display apparatus according to claim 1, wherein, in addition to an image signal input to the image forming device, observation position information regarding the observation position of the observer is transmitted to the display apparatus from outside the display apparatus.

4. The display apparatus according to claim 1, wherein the convergence angle is further adjusted by controlling an image signal input to the image forming device that configures the image displaying device.

5. A display apparatus comprising:

a glass-type frame configured to be mounted to a head of an observer;

an image displaying device attached to the glass-type frame, the image displaying device comprising;

an image forming device,

an optical system, and

a rotary movement device responsive to a control signal to rotate the image forming device and the optical system, to adjust a convergence angle of a virtual image provided by the image forming device; and

a control device configured to provide the control signal to the rotary movement device to adjust the convergence angle based on observation position information of the observer, wherein the observation position information of the observer permits adjustment of the convergence angle of the virtual image provided by the image forming device relative to a convergence angle of an observation target.

6. The display apparatus according to claim 5, wherein observation position information regarding the observation position of the observer is given to the display apparatus in advance.

7. The display apparatus according to claim 5, wherein, in addition to an image signal input to the image forming device, observation position information regarding the observation position of the observer is transmitted to the display apparatus from outside the display apparatus.

8. The display apparatus according to claim 5, wherein the convergence angle is adjusted by controlling an image signal input to the image forming device that configures the image displaying device.

9. A display apparatus comprising an image displaying device, the image displaying device comprising:

an image forming device,

a lens,

a movement device responsive to a control signal to relatively move an optical axis of the image forming device and an optical axis of the lens, and

a control device configured to provide the control signal to the movement device to adjust a convergence angle of a virtual image provided by the image forming device based on observation position information of the observer, wherein the observation position information of the observer permits adjustment of the convergence angle of the virtual image provided by the image forming device relative to a convergence angle of an observation target.
