Stereo video image display apparatus and stereo video image display method
A stereo video image display apparatus includes a data obtaining unit, a video image generator and an image quality degradation unit. The data obtaining unit obtains left eye video image data and right eye video image data. The video image generator generates sequential data in which a left eye video image data sequence repeating the left eye video image data and a right eye video image data sequence repeating the right eye video image data are arranged alternately to generate a control signal controlling opening and closing of shutter glasses according to the sequential data. The image quality degradation unit processes image quality degradation for object data which is frame data corresponding to one frame either before the switching between the left eye video image data and the right eye video image data and one frame after the switching, or two frames before and after the switching.
1. A stereo video image display apparatus comprising:
a data obtaining unit that obtains left eye video image data and right eye video image data for stereo video image perception by binocular parallax;
a video image generator that generates sequential data in which a left eye video image data sequence repeating the obtained left eye video image data three times and a right eye video image data sequence repeating the obtained right eye video image data three times are arranged alternately to generate a control signal which controls opening and closing of shutter glasses according to the sequential data;
an image quality degradation unit that processes image quality degradation for object data which is frame data corresponding to either one of one frame before switching between the left eye video image data and the right eye video image data and one frame after the switching or object data which is frame data corresponding to two frames before and after the switching, in the sequential data; and
a display unit that displays a video image according to the sequential data after image quality of the object data has been degraded.
2. The stereo video image display apparatus according to claim 1 , wherein the image quality degradation unit degrades the image quality of the object data by obscuring an outline in the object data.
3. The stereo video image display apparatus according to claim 2 , wherein the image quality degradation unit obscures the outline in the object data by causing the object data to pass through a filter.
4. The stereo video image display apparatus according to claim 1 , wherein the image quality degradation unit degrades the image quality of the object data by reducing a contrast range of the object data.
5. The stereo video image display apparatus according to claim 1 , wherein the video image generator generates the control signal which opens a left eye shutter and closes a right eye shutter in the shutter glasses for a whole period in which a video image according to the left eye video image data sequence is displayed, and closes the left eye shutter and opens the right eye shutter in the shutter glasses for a whole period in which a video image according to the right eye video image data sequence is displayed.
6. The stereo video image display apparatus according to claim 1 , wherein the object data is the frame data corresponding to one frame after the switching between the left eye video image data and the right eye video image data, in the sequential data.
7. A stereo video image display method comprising:
obtaining left eye video image data and right eye video image data for stereo video image perception by binocular parallax;
generating sequential data in which a left eye video image data sequence repeating the obtained left eye video image data three times and a right eye video image data sequence repeating the obtained right eye video image data three times are arranged alternately to generate a control signal which controls opening and closing of shutter glasses according to the sequential data;
processing image quality degradation for object data which is frame data corresponding to either one of one frame before switching between the left eye video image data and the right eye video image data and one frame after the switching or object data which is frame data corresponding to two frames before and after the switching, in the sequential data; and
displaying a video image according to the sequential data after image quality of the object data has been degraded.
8. The stereo video image display method according to claim 7 , wherein the processing degrades the image quality of the object data by obscuring an outline in the object data.
9. The stereo video image display method according to claim 8 , wherein the processing obscures the outline in the object data by causing the object data to pass through a filter.
10. The stereo video image display method according to claim 7 , wherein the processing degrades the image quality of the object data by reducing a contrast range of the object data.
11. The stereo video image display method according to claim 7 , wherein the generating generates the control signal which opens a left eye shutter and closes a right eye shutter in the shutter glasses for a whole period in which a video image according to the left eye video image data sequence is displayed, and closes the left eye shutter and opens the right eye shutter in the shutter glasses for a whole period in which a video image according to the right eye video image data sequence is displayed.
12. The stereo video image display method according to claim 7 , wherein the object data is the frame data corresponding to one frame after the switching between the left eye video image data and the right eye video image data, in the sequential data.
