2. Background Art imagesarepercelvedbyoureyeswhenweThree-dimensional(3-D) see third images formed in our eyes from the real images projecte on the screen. The way to form third images is to see left and right images separately with the corresponding eye at each side.
Conventional 3-D films for the cinema are made by taking pictures of objects with a pair of camera, one of which picture is in red color and the other in green color. The two films are simultaneously projecte on the screen to form overlapped images and their images are not separated when viewed through naked normal eyes. The viewer shall wear a pair of colored glasses, one of which is in red color and the other in green co ! or to separate the overlapped images. Then, the red theprojectedimagesdisappearsintheredglassandthegreencolorof color of the projected images disappears in the green glass. The viewer sees separated images of the two films through the two glasses of-different colors-green images through the red glass and red images through the green glass. These images are seen as the 3-D images in the eyes of the viewer wearing the red glass and green one.
IMEX cinema is filmed with a special high-speed camera and played at a high speed on a very large screen to form the 3-D images. 3-D images are also made with computer graphics but this process is not widely used because of high production cost and complicate production procedure.
The electronic 3-D images such as cyber-experiences are produced by taking pictures of objects simultaneously with a pair of cameras and by playing the two pictures simultaneously on one monitor screen.
The images are overlapped and so a pair of specia ! glasses is required to separate the images,which form 3-D images in human eyes.
3. Disclosure of Invention When an object is viewed through right and left eyes, the image seen through the right eye is slightly different the one seen through the left eye. However, when when the object is simultaneously seen through the two eyes. the images seen throughthetwoeyesmergeintooneand!ook three-dimensionat.
A pair of high-speed cameras is installe at a distance of between two eyes with their lenses focused on the object. When two images taken by the two cameras are simultaneously nlayed on one screen to be overlapped, the quality of the picture is poor and unsuitable for commercial purpose. However, when the film in edited in such an alternate way as to arrange the frames as follows, a pair of two s'ight'y different images will be merged into a 3-D image : frames><Arrangementof The first frame of the right camera picture, the first frame of the left camera picture, the second frame of the right camera picture, the second frame of the left camera picture, the third frame of the right camera picture and so on.
The 3-D images thus acquired can be recorde at normal speed with a norma !-speed camera and the recorde tape (or film) can be ptayed on the conventiona ! monitor screen of VCP or on the cinema screen to display the 3-D pictures.

Best Mode for Carrying Out the Invention 6. mdustnat Applicability One of the largest business in the world in early 21st century is expected to be 3-D image TV broadcasting and many electronic communication companies are devoted to the research and development of 3-D images.
When such system of color 3-D image broadcasting is available, it will face instantaneous worldwide demand.
