- onventional TV could display objects in 2D (2 dimensional image) only. So it is impossible to express the natural depth and presence they have in the real world.
In contrast, 3-dimensional (3-D) imaging applies the knowledge that humans see things with two eyes that are set slightly apart, to reproduce a sense of depth In addition to horizontal and vertical information. 3D more closely resembles the way people sense space, creating a new way of visual expressions.
- When shooting a 3D image, two lenses are used to capture separate images of the same object from different angles. Containing twice as much information as conventional 2D images, 3D images are then edited while maintaining the information from both angles.
When the medium is played back, the left-hand image is shown only to your left eye and the right-hand image only to your right eye. These two images combine in your brain to give you a perception of depth.
- ecause there is separation between the eyes in humans, each eye sees the world from a different angle. If you cover one eye, and then alternately the other, you will see things differently each time - and can perceive the difference in angle.
A combination of the individual images seen by each eye creates a perception of depth and dimension in the brain. This is called “parallax”, and it is the base on which 3D imaging technologies were created.
