Video display control method and apparatus

摘要

Stereoscopic video content is reproduced to obtain a first pair of images with mutual parallax producing a stereoscopic effect. A first stereoscopic adjustment on the first pair of images is carried out to obtain a second pair of images. A second stereoscopic adjustment on the second pair of images is carried out to obtain a third pair of images, which are displayed on a screen to respective eyes of the viewer. The first stereoscopic adjustment is carried out differently for different video sources. The second stereoscopic adjustment is the same for all sources. The combination of the first and second stereoscopic adjustments enables content from different sources to be displayed with an appropriate stereoscopic adjustment for each source.

1. A video display control method comprising the steps of:
reproducing, using a stereoscopic video content reproducing device, stereoscopic video content of a first type to obtain a first pair of images with mutual parallax; performing, using the stereoscopic video content reproducing device, a first stereoscopic adjustment that modifies the first pair of images based on a first set of parameter values, thereby obtaining a second pair of images; inputting the second pair of images to a stereoscopic video display device having a single screen; performing, using the stereoscopic video display device, a second stereoscopic adjustment that modifies the second pair of images based on a second set of parameter values, thereby obtaining a third pair of images; and displaying the third pair of images on the screen as images to respective eyes of a viewer, wherein said second stereoscopic adjustment is performed in coordination with the first stereoscopic adjustment by transmitting the first set of parameter values to the stereoscopic video display device and transmitting the second set of parameter values to the stereoscopic video content reproducing device, said first stereoscopic adjustment modifies the first pair of images by horizontal scaling of both of the first pair of images and horizontal shifting of at least one of the first pair of images to align a left edge of one of the resulting second pair of images with a left edge of the screen and align a right edge of the other one of the resulting second pair of images with a right edge of the screen using the first set of parameter values, and said second stereoscopic adjustment is different from the first stereoscopic adjustment and modifies the second pair of images by horizontal scaling of both of the second pair of images and horizontal shifting of at least one of the second pair of images to align a left edge of one of the resulting third pair of images with a left edge of the screen and align a right edge of the other one of the resulting third pair of images with a right edge of the screen using the second set of parameter values which are determined based on stored adjustment parameter values and the first set of parameter values received from the stereoscopic video content reproducing device.
