3D comes home
Have you had this experience? You are watching a movie. A man is shooting on the screen. The picture is so real that you think he is shooting at you. Or a car is speeding on the screen and at one point you are afraid it will hit you.
Three-dimensional (3D)films use special technology to make pictures seem more real and exciting than two-dimensional ones. Two popular movies in the cinema this year, UP and Ice Age; Dawn of the Dinosaurs both use 3D technology.
So far we can only see 3D films in the cinema with a special screen and projector. But soon, we will be able to watch them in our living rooms. Last month, the Japanese company Sony told reporters that it plans to bring 3D televisions to homes in 2010. The company is also hoping to make other products with 3D, like laptops and PS3.
“ The 3D train is on the track, and we are ready to drive it home,” said Sony President Sir Howard Stringer.
How 3D technology works
Three dimensional movies and TV programs are fun to watch, but do you know how they are made? It is much easier to understand if we do an experiment.
Hold one of your fingers up at arms length and close one eye. Then try closing the other eye. As you switch between open eyes you should see your finger “jumping” left and right against the background.
This happens because our two eyes are about 4 cm away from each other. The separation causes each eye to see the world from a different angle. The brain puts these two views together. What you see becomes three-dimensional.
Three dimensional movies are made using two video cameras at the same time, which creates two different images. When the movie plays in a cinema, two projectors put the two images on the screen. With a pair of 3D glasses, the two images are separated and each image only enters one eye. Your brain puts the two pictures back together, and the pictures on the screen become three-dimensional.
