How Does 3D Technology Work?

Digital image

Human eyes are approximately 50 mm to 75 mm apart — accordingly, each eye sees a slightly different part of the world. Hold up a pen, pencil or any other thin object. The image on either side should be pretty similar but slightly offset, like that line behind the woman's head in the picture above. These two slightly different images enter the brain, at which point it does some high-powered geometry to make up for the disparity between the two images. This disparity is "3D" — essentially, your brain making up for the fact that you're getting two different perspectives of the same thing.

This is also, essentially, what modern 3D technology is trying to replicate. All those silly sunglasses and silver-coated projectors are all designed to feed your individual eyes different perspectives of the same image. It is pretty easy for your brain to figure out the disparity between the two images. Your brain can automatically figure out all the angles and math and geometry to sync the images.

The hard part is getting a camera to do the same thing, and to get those individual images to your individual eyes without butchering the whole effect.

What We Watch Films Film has been one of the pioneers of 3D, thanks to its hefty budgets and some technological daring. There are largely two ways 3D has been achieved in motion pictures: Anaglyph is a fancy way of referring to the red-and-blue glasses we used to wear.

By projecting a film in those colors — one in red, one in blue — each eye would get an individual perspective and your brain would put the 3D effect together. Other colors could be used, providing they were distinct enough to be separated on screen.

This technique, however, didn't allow for a full range of color and had a tendency to "ghost," or have the once-distinct images bleed into one another.

Much more common is the use of polarized glasses, which take advantage of the fact that light can be polarized, or given different orientations.

For example, one image can be projected in a horizontal direction while the second can be projected in a vertical direction. The corresponding glasses would allow horizontal polarization in one eye and vertical polarization in the other. Tilting your head can distort how the waves get to your eyes, messing with the color and 3D effect.

This is the tricky part.

To counteract this, 3D now uses rotational polarity, meaning the film being projected actually has two different spins to it. The glasses then pick up those opposite rotations — clockwise in one eye, counterclockwise in another eye — to separate the image.

Television It's possible to use the same techniques in film projectors for home theaters, but you would need some serious cash. Films use special silver-coated screens that are much better at reflecting light back to the viewing audience. Your television, unfortunately, is not silver-coated. There are, however, two ways to get 3D at home: The most common, active 3D, involves wearing those electronic RoboCop glasses. The glasses are synced up to your television and actively open and close shutters in front of your eyes, allowing only one eye to see the screen at a time.

This sounds like a recipe for a stroke, but the shutters move so quickly that they're hardly noticeable. These shutter lenses are made possible because of the refresh rate on televisions.

Through the glasses, you receive one constant image instead of a flicker. Passive systems are less common but run much like your 3D film. These televisions have a thin, lenticular screen over the standard display.

A lenticular screen is made up of a series of incredibly thin magnifying strips that show a slightly different perspective of the screen to each eye, as illustrated above. While this technology doesn't require bulky, expensive glasses, it can limit the image quality.

Essentially, each eye only sees one half of the screen at any given time. For example, if a screen had pixels, 50 pixels would be magnified and sent to the left eye and the other 50 pixels would be magnified and sent to the right eye. In practice, your brain is actually able to put the two images together and retain the entire pixel fidelity.

The real heavy lifting, however, is all just a matter of geometry and precision. To get a 3D image, you essentially need two versions of the same scene filmed from the precisely correct angle as if your eyes were seeing the same scene.

Filmmakers need to triangulate the distance between the two cameras and make sure they are focused on the same object. They also need to zoom and track, or move, at the same speed, otherwise the images won't sync up. The field of digital image processing is the study of algorithms for their transformation. Raster file formats[ edit ] Most users come into contact with raster images through digital cameras, which use any of several image file formats.

Some digital cameras give access to almost all the data captured by the camera, using a raw image format.

These file formats allow the photographer and the processing agent the greatest level of control and accuracy for output. Their use is inhibited by the prevalence of proprietary information trade secrets for some camera makers, but there have been initiatives such as OpenRAW to influence manufacturers to release these records publicly. An alternative may be Digital Negative DNGa proprietary Adobe product described as "the public, archival format for digital camera raw data".

In mathematical terms, a vector consists of point that has both direction and length. Often, both raster and vector elements will be combined in one image; for example, in the case of a billboard with text vector and photographs raster. Image viewing[ edit ] Image viewer software displays images. In the past, when Internet was still slow, it was common to provide "preview" image that would load and appear on the web site before being replaced by the main image to give at preliminary impression.

Now Internet is fast enough and this preview image is seldom used. Some scientific images can be very large for instance, the 46 gigapixel size image of the Milky Wayabout Gb in size.
