Display device and display method
The display device includes a first liquid crystal panel that displays a first image, a second liquid crystal panel that faces a rear surface of the first liquid crystal panel and displays a second image synchronized with the first image, and an image enlargement processing unit configured to generate the second image to be displayed on the second liquid crystal panel by enlargement from a predetermined enlargement center position toward at least one end portion of the second liquid crystal panel.
1. A display device comprising:
a first liquid crystal panel configured to display a first image;
a second liquid crystal panel facing a rear surface of the first liquid crystal panel and configured to display a second image synchronized with the first image; and
an image enlargement processing unit configured to generate the second image to be displayed on the second liquid crystal panel by enlarging a pre-enlargement image from a predetermined enlargement center position toward at least one end portion of the second liquid crystal panel,
wherein the image enlargement processing unit enlarges the pre-enlargement image, being an image before an enlargement of the second image, in such a manner that a position of a pre-enlargement display element of the pre-enlargement image gets close to the at least one end portion to generate the second image, the pre-enlargement display element being a partial region closer to the at least one end portion than the predetermined enlargement center position.
2. The display device according to claim 1 ,
wherein the image enlargement processing unit enlarges the pre-enlargement image, being the image before the enlargement of the second image, from the predetermined enlargement center position isotropically in both a horizontal direction and a vertical direction in a display region of the second liquid crystal panel to generate the second image.
3. The display device according to claim 1 , further comprising:
an input device configured to input a parameter that includes information for adjusting a display position of the second image in a display region of the second liquid crystal panel.
4. The display device according to claim 1 , further comprising:
an angle adjustment mechanism configured to adjust angles of the first liquid crystal panel and the second liquid crystal panel.
5. The display device according to claim 1 , further comprising:
a position determination unit configured to determine a position of a viewer,
wherein the image enlargement processing unit sets the predetermined enlargement center position in accordance with the position of the viewer determined by the position determination unit.
6. The display device according to claim 1 , further comprising:
an input device configured to input position information indicating the predetermined enlargement center position,
wherein the image enlargement processing unit sets the predetermined enlargement center position in accordance with a position input by the input device.
7. A display device comprising:
a first liquid crystal panel configured to display a first image;
a second liquid crystal panel facing a rear surface of the first liquid crystal panel and configured to display a second image synchronized with the first image;
an image enlargement processing unit configured to generate the second image to be displayed on the second liquid crystal panel by enlarging a pre-enlargement image from a predetermined enlargement center position toward at least one end portion of the second liquid crystal panel;
a liquid crystal panel extension processing unit configured to perform filtering to generate the pre-enlargement image, being an image before an enlargement of the second image, by the image enlargement processing unit; and
an input device configured to input at least one of a first parameter and a second parameter, the first parameter including information for the liquid crystal panel extension processing unit to perform the filtering, and the second parameter including information for the image enlargement processing unit to enlarge the pre-enlargement image.
8. A display method comprising:
displaying a first image on a first liquid crystal panel;
displaying a second image synchronized with the first image on a second liquid crystal panel facing a rear surface of the first liquid crystal panel;
generating the second image by enlarging a pre-enlargement image from a predetermined enlargement center position in the second liquid crystal panel toward at least one end portion of the second liquid crystal panel; and
enlarging the pre-enlargement image, being an image before an enlargement of the second image, in such a manner that a position of a pre-enlargement display element of the pre-enlargement image gets close to the at least one end portion to generate the second image, the pre-enlargement display element being a partial region closer to the at least one end portion than the predetermined enlargement center position.
