VB最新情報と3D映像の秘密
Latest VB Information & Secrets of 3D Images

右目と左目は
見え方が違う
Objects Look Different from the Left Eye than the Right

自分の顔を鏡で見てみよう。目が2つあって、その2つの目は左右に間隔を置いて顔に付いているハズだ。そのため、なにか物体を見るときに、右の目と左の目では違って見えているのだ。これを視差という。VBはこれを利用して最初から視差のある画面を左右の目に見せている。だから立体に見えるというワケだ。
If you take a look at your face in a mirror, you’ll notice that with your two eyes on your face, there is a space between the left one and the right. Because of this, when you look at an object, your right eye and your left eye see it differently. This is called “parallax.” By taking advantage of this, the VB displays screens, which utilize parallax, to one’s left eye and right eye from the beginning. That’s why objects in the VB appear to be three-dimensional!

右目は物体の右、左目は左の側面を
余分に見ているのがわかるかな?
Can you see that the left eye sees more of the left side of an object, while the right eye sees more of the right side?

実験してみよう
Let’s Experiment

まだ視差の意味がピンとこない人は実験してみう。まず鉛筆を真っ直ぐ鼻の前に立ててテレビのモニターの前に距離を置いて立ち、片目ずつ見比べてみよう。するとモニターの位置は少しズレて見えるが、近くにある鉛筆はもっと大きくズレて見えるだろう。
このような左右の見ためのズレを視差という。VBはこの視差のある2つの絵を見せて立体に見せているのだ。
For those who still don’t quite understand parallax, let’s do an experiment. While being at some distance in front of a TV monitor, hold a pencil right in front of your nose, and now compare the scene with each eye, one at a time. The monitor will appear to shift its position a little bit, whereas the nearby pencil will appear to shift much more!
The apparent shifting of something to the left or right like this is called “parallax.” In order to display something three-dimensionally, the VB displays two images with such a parallax relationship.

これは近すぎ。もっと離れてね
This is too close, so be further away.

いわゆる視差だ!
This is the So-Called Parallax!

右目
Right Eye

右目では鉛筆がモニターの左側にある。次は左目に挑戦
With your right eye, the pencil is on the left side of the monitor. Next, try your left eye!

左目
Left Eye

モニターの位置はあまり変わらないが、鉛筆は右に移動
The monitor’s position doesn’t change very much, but the pencil moves to the right!

脳あってのVB
The VB and the Brain

VBは右目用と左目用の画面を同時に見せて疑似立体を作るマシンだ、ということはわかったかな?
目に写ったVBの画面はその後、網膜で光と色の2つのデータに分かれ視神経によって脳に伝わる。そして、脳の中で数多くの脳細胞がデータを細分化チェックし、最終的に左右の目のデータを脳で1つの立体映像にしているのだ。
Did you know that the VB is a machine that shows pseudo-three-dimensional objects by simultaneously displaying a screen for the right eye and a screen for the left eye? The screens of the VB are projected into the eyes and, after that, are divided into two sets of data of light and color in the retina and are then transmitted to the brain by the optic nerve. Then, many brain cells in the brain check the data subdivision and ultimately make the left-eye data and the right-eye data into a single stereoscopic image in the brain.
