Abstract

At the time of displaying a targeted stereoscopic image composed of a background image being a planar component and a flying-out image being a stereoscopic component, a stereoscopic display device controls and stereoscopically displays the flying-out image being large in parallax so that the amount of transmitted light of a light transmitting portion of a light control panel becomes T1 (step S103 and step S104). Thereafter, it changes over the amount of transmitted light of the light transmitting portion of the light control panel from T1 to T2 larger than T1 (step S105). And it plane-displays a background image being smaller in parallax (step S106).

Claims

1-9. -9. (canceled)

10. A device that displays flat images producing binocular parallax and performs stereoscopic display, the device comprising:

a display unit that, based on input image data, displays a plurality of flat images that are components of a stereoscopic image, and

a light control unit that adjusts an amount of light transmitted from the display unit and is disposed between the display unit and a user viewing the display unit, wherein

the light control unit has

an opaque base body,

a plurality of sections that are formed on the base body, have a planar dimension, transmit an amount of light, and are visible domains of the flat images, and

an adjusting unit that adjusts the amount of light transmitted by adjusting the planar dimension of the sections, and

the device displays the stereoscopic image by switching, at a frequency of at least 15 Hz, a stereoscopic display and a flat display, wherein the stereoscopic display has the amount of light transmitted by the sections adjusted to a first amount and the flat display has the amount of light transmitted by the sections adjusted to a second amount larger than the first amount.

11. The device according to claim 10, wherein

the display unit selectively and sequentially displays the flat images,

among the sections, the light control unit makes a specified section, an optically transmissible section and a non-specified section, an opaque section, and selectively and sequentially performs a position change of the optically transmissible sections,

the flat images to be displayed on the display unit are updated synchronously with the position change of the optically transmissible sections, and

the flat images corresponding to the optically transmissible sections are displayed.

12. The device according to claim 10, wherein the stereoscopic display and the flat display are switched over time.

13. The device according to claim 10, wherein the stereoscopic display displays a portion of the stereoscopic image domains and the flat display displays domains excluding the portion of the stereoscopic image domains.

14. The device according to claim 10, further comprising a determining unit that determines whether the stereoscopic display or the flat display is to be performed based on the parallax between the planar images, wherein

the adjusting unit adjusts the planar dimension of the sections according to a determination result of the determining unit.

15. The device according to claim 14, wherein the determining unit determines whether the stereoscopic display or the flat display is to be performed by detecting a similarity amongst image data according to respective flat images, and by obtaining the parallax between the flat images from the similarity detected.

16. The device according to claim 14, wherein

the image data corresponding to each of the flat images includes determination information indicating whether the stereoscopic display or the planar display is to be performed, and

the determining unit determines whether the stereoscopic display or the planar display is to be performed based on the determination information.

17. The device according to claim 10, wherein emission brightness of the display unit for the flat display is reduced to a level lower than that of the display unit for the stereoscopic display.
