Abstract
This display device is provided with a display unit and a control unit. The display unit projects and reflects, onto a light-transmitting display medium, light expressing an image, to allow the image to be viewed, as a virtual image, by a user. The control unit performs first stereoscopic display processing for causing light respectively expressing a left-eye image and a right-eye image of an object to be displayed, to be projected in the display unit. As a result of this processing, the object to be displayed can be stereoscopically viewed in a three-dimensional image space by the user.
Claims9
A display device comprising:
- a display that projects light indicating an image to a display medium with translucency and reflects the light to the display medium to allow a user to visually recognize the image as a virtual image;
- a memory that stores instructions;
- a processor which, when executing the instructions stored in the memory, performs operations comprising:
- performing a first stereoscopic display process for projecting light indicating each of first image for a left eye and a first image for a right eye of a display object on the display such that a stereoscopic view of the display object is displayed to the user in a three-dimensional image space,
- determining whether a display distance, that is a distance from a display standard position of the three-dimensional image space in a depth direction to a position of the display object, is greater than or equal to than a predetermined threshold value,
- performing a second stereoscopic display process with respect to each of a plurality of portions of a pattern in sequential order from a near side toward a far side in the image space, for projecting light indicating each of a second image for a left eye and a second image for a right eye of each portion of the plurality of portions of the pattern, such that a stereoscopic view of the pattern is displayed to the user when it is determined that the display distance is greater than or equal to the threshold value.
A display method using a display that projects light indicating an image to a display medium with translucency and reflects the light to the display medium to allow a user to visually recognize the image as a virtual image, the method comprising:
- performing a first stereoscopic display process for projecting light indicating each of a first image for a left eye and first image for a right eye of a display object on the display such that a stereoscopic view of the display object is displayed to the user in a three-dimensional image space;
- determining whether a display distance, which is a distance from a display standard position of the three-dimensional image space in a depth direction to a position of the display object, is greater than or equal to a predetermined threshold value;
- and
- performing a second stereoscopic display process with respect to each of a plurality of portions of a pattern in sequential order from a near side toward a far side in the image space, for projecting light indicating each of a second image for a left eye and a second image for a right eye of each portion of the plurality of portions of the pattern, such that a stereoscopic view of the pattern is displayed to the user when it is determined that the display distance is greater than or equal to the threshold value.
