A Unique 3D Technology for Cinema
Dolby 3D differs from other 3D cinema technologies and provides an experience completely faithful to what the movie's creators envisioned. Dolby 3D uses a unique full-spectrum color technology that provides extremely crisp, clear images. The Dolby 3D movie system has a rotating color filter wheel that can insert automatically into a digital projector for 3D movies.
Inside the projector, the wheel filters the light before the image is formed, resulting in an unaltered image with both its color and quality preserved. For 2D movies, the wheel can be set to automatically retract, avoiding any of the picture-quality issues caused by 3D filters being left in place for 2D shows.
Dolby 3D projects full-color images for the left and right eyes. The projection uses two slightly different sets of primary colors. The audience wears passive 3D glasses with complementary filters precisely tuned to match the filters in the projector, ensuring that each eye sees the correct image.
Alongside the projector, the Dolby Filter Controller automatically synchronizes the filter wheel with the 3D digital content as it's projected.
The Dolby 3D image delivers full quality when projected onto a conventional white screen. Other cinema 3D methods require a highly reflective silver screen to achieve a bright-enough image. However, the silver screen can degrade the 2D experience.
