Display device and display method
A display device includes: a display unit displaying plural viewpoint images; a light separation unit having plural transmitting portions and separating light from the display unit; and a display control unit controlling the timing of switching either of display positions of respective viewpoint images on the display unit and transmittance of respective transmitting portions of the light separation unit based on correlation information of the viewpoint images between frames.
1. A display device comprising:
a display unit displaying plural viewpoint images;
a light separation unit having plural transmitting portions and separating light from the display unit; and
a display control unit controlling the timing of switching either of display positions of respective viewpoint images on the display unit and transmittance of respective transmitting portions of the light separation unit based on correlation information of the viewpoint images between frames,
wherein the display control unit controls the switching timing based on at least one of:
a scene change of viewpoint images detected as correlation information of the viewpoint images between frames, and
a variation degree in viewpoint images detected as correlation information of the viewpoint images between frames.
2. The display device according to claim 1 ,
wherein the display control unit acquires a position of an observer and switches at least either of display positions of respective viewpoint images and transmittance of respective transmitting portions so that central images of the plural viewpoint images come close to the position of the observer at the switching timing.
3. The display device according to claim 2 ,
wherein the display control unit acquires the position of the observer and switches at least either of display positions of respective viewpoint images and transmittance of respective transmitting portions so that the central images of the plural viewpoint images are arranged at the position of the observer at the switching timing.
4. The display device according to claim 3 ,
wherein the display control unit acquires the position of the observer and switches at least either of display positions of respective viewpoint images and transmittance of respective transmitting portions so that the central images of the viewpoint images come close to the position of the observer in the case where the central images of the plural viewpoint images are not arranged at the position of the observer at the switching timing.
5. The display device according to claim 1 ,
wherein the display control unit acquires the position of the observer and switches at least either of display positions of respective viewpoint images and transmittance of respective transmitting portions in the case where the observer is in a pseudoscopic area at the switching timing.
6. The display device according to claim 1 ,
wherein the display control unit acquires the position of the observer and switches at least either of display positions of respective viewpoint images and transmittance of respective transmitting portions in the case where the observer is in the pseudoscopic area or in a quasi-orthoscopic area adjacent to the pseudoscopic area at the switching timing.
7. The display device according to claim 1 ,
wherein the display control unit acquires the position of the observer and does not switch at least either of display positions of respective viewpoint images and transmittance of respective transmitting portions in the case where the observer is in an orthoscopic area at the switching timing.
8. The display device according to claim 1 ,
wherein the display control unit does not switch at least either of display positions of respective viewpoint images and transmittance of respective transmitting portions in the case where a variation of the position of the observer is lower than a given threshold value.
9. The display device according to claim 1 ,
wherein the display control unit acquires positions of plural observers and switches at least either of display positions of respective viewpoint images and transmittance of respective transmitting portions at the switching timing in the case where all plural observers can view the images in the orthoscopic area after the switching.
10. A display device comprising:
a display unit displaying plural viewpoint images;
a parallax barrier including plural transmitting portions; and
a control unit,
wherein the control unit performs control of switching display positions of respective viewpoint images or positions of transmitting portions in accordance with a scene change of the viewpoint images.
11. A display method comprising:
acquiring correlation information of plural viewpoint images between frames displayed on a display unit; and
controlling the timing of switching at least either of display positions of respective viewpoint images on the display unit and transmittance of respective transmitting portions of a light separation unit including plural transmitting portions separating light from the display unit based on the acquired correlation information of the viewpoint images between frames,
wherein the display control unit controls the switching timing based on at least one of:
a scene change of viewpoint images detected as correlation information of the viewpoint images between frames, and
a variation degree in viewpoint images detected as correlation information of the viewpoint images between frames.
