Abstract
A 3D display device includes a display panel, an optical element, a second communication module, and a controller. The display panel is mounted on a moving body and configured to display a parallax image. The optical element is configured to define a propagation direction of image light emitted from the display panel. The second communication module is configured to receive a motion signal indicating a parameter of a motion of the moving body. The controller is configured to cause the display panel to display the parallax image based on the parameter indicated by the motion signal.
Claims9
A 3D display device, comprising:
- a display panel mounted on a moving vehicle in which a user is, the display panel displaying a parallax image to the user;
- an optical element which defines a propagation direction of image light emitted from the display panel;
- a communication circuitry which receives a motion signal indicating a parameter of a motion of the moving vehicle, the parameter including acceleration indicating a change in the motion of the moving vehicle;
- a controller which causes the display panel to display the parallax image based on the parameter indicated by the motion signal;
- an imaging device having an imaging range containing a face of the user;
- and
- a table provided in the controller, the table storing data indicating correspondence between acceleration of the moving vehicle in an inter-eye direction of the user and positions of eyes of the user in the inter-eye direction,
- wherein, when first positions of the eyes estimated based on a captured image generated by the imaging device and second positions of the eyes estimated based on the acceleration in the inter-eye direction indicated by the motion signal are different from each other, the controller calibrates the data stored in the table by using a difference between the first positions and the second positions.
A head-up display, comprising:
- a 3D display device comprising a display panel mounted on a moving vehicle in which a user is, the display panel displaying a parallax image to the user, an optical element which defines a propagation direction of image light emitted from the display panel, a communication circuitry which receives a motion signal indicating a parameter of a motion of the moving vehicle, the parameter including acceleration indicating a change in the motion of the moving vehicle, a controller which causes the display panel to display the parallax image based on the parameter indicated by the motion signal, an imaging device having an imaging range containing a face of the user, and a table provided in the controller, the table storing data indicating correspondence between acceleration of the moving vehicle in an inter-eye direction of the user and positions of eyes of the user in the inter-eye direction;
- and
- an optical member which reflects the image light emitted from the 3D display device and causes the reflected light to reach the eyes of the user,
- wherein, when first positions of the eyes estimated based on a captured image generated by the imaging device and second positions of the eyes estimated based on the acceleration in the inter-eye direction indicated by the motion signal are different from each other, the controller calibrates the data stored in the table by using a difference between the first positions and the second positions.
A moving vehicle, comprising:
- a head-up display comprising
- a 3D display device comprising a display panel which displays a parallax image to a user, an optical element which defines a propagation direction of image light emitted from the display panel, a communication circuitry which receives a motion signal indicating a parameter of a motion of the moving vehicle, the parameter including acceleration indicating a change in the motion of the moving vehicle, and a controller which causes the display panel to display the parallax image based on the parameter indicated by the motion signal,
- an optical member which reflects the image light emitted from the 3D display device and causes the reflected image light to reach the eyes of the user,
- an imaging device having an imaging range containing a face of the user, and
- a table provided in the controller, the table storing data indicating correspondence between acceleration of the moving vehicle in an inter-eye direction of the user and positions of eyes of the user in the inter-eye direction,
- wherein, when first positions of the eyes estimated based on a captured image generated by the imaging device and second positions of the eyes estimated based on the acceleration in the inter-eye direction indicated by the motion signal are different from each other, the controller calibrates the data stored in the table by using a difference between the first positions and the second positions.
A program of activating a 3D display device mounted on a moving vehicle, the 3D display device comprising a display panel which displays a parallax image for a user, an optical element which defines a propagation direction of image light emitted from the display panel, an imaging device having an imaging range containing a face of the user, a communication circuitry, and a controller which includes a table storing data indicating correspondence between acceleration of the moving vehicle in an inter-eye direction of the user and positions of eyes of the user in the inter-eye direction, the program being provided in the controller and comprising:
- activating the controller to cause the communication circuitry to receive a motion signal indicating a parameter of a motion of the moving vehicle, the parameter including acceleration indicating a change in the motion of the moving vehicle;
- and
- activating the controller to cause the display panel to display the parallax image based on the parameter and, when first positions of the eyes estimated based on a captured image generated by the imaging device and second positions of the eyes estimated based on the acceleration in the inter-eye direction indicated by the motion signal are different from each other, calibrate the data stored in the table by using a difference between the first positions and the second positions.
