Snap First, Focus Later with New Digital Camera
A Silicon Valley start-up company has released a new camera model that allows a user to snap first and focus later.Dubbed 'Lytro', the camera is able to capture light data from many different angles using a specialized sensor. The sensor uses what is called a "microlens array", which packs the equivalent of many camera lenses into a very small space.
Images Become Living, Interactive Pictures
The light information captured by the Lytro is significantly more than a conventional camera and is later focused and refined using a computer.
Focal points of the image are navigated using a few mouse clicks, allowing the user to sharpen the image at certain points. (Source: ibtimes.com) The viewer can literally navigate through the image to get a semblance of different perspectives.
As Lytro founder and chief executive Ren Ng states, "They (the images) become interactive, living pictures."
"Shutter Lag" Removed Altogether
In addition to these innovative features, the camera itself is much faster than its conventional counterparts due to the removal of the "shutter lag" (the time it takes for the autofocus to kick in). These fractions of a second are often the times when an unsuspecting subject moves from their pose.
Furthermore, Lytro cameras are also able to capture 3D images, which can be viewed later on a computer screen with the aid of 3D glasses.
Lytro Set to Rival Camera Giants
Lytro has since decided to remain an independent entity and gamble with their innovation, rather than license their technology to a camera giant like Canon or Nikon. Investors have already put $50 million into the Lytro effort. (Source: nytimes.com)
While the company is remaining tight-lipped about the price of the camera, they insist that it will be designed for the consumer market. The first batch of cameras will initially be sold through online retailers like Amazon.com and the Lytro website.

A camera that couldn't care less about focus: Introducing Lytro
Updated 6h 36m ago

By Chris Taylor, MashableRemember cameras that would have to focus themselves before taking a snapshot? And how that could lose vital seconds, making a mockery of the term "point and shoot"?
Oh, right -- that would describe every digital camera currently on the market. But if one Silicon Valley start-up has its way, the very idea of focusing, or adjusting light levels, or having to wait before you click the shutter, will be a relic of the early 21st century -- along, perhaps, with photos that only exist in two dimensions.
Lytro is the brainchild of Ren Ng, a Stanford Ph.D. whose dissertation on light-field technology five years ago was showered with awards. Now, with the help of $50 million in funding, most of it from Andreessen Horowitz, Ng has built a company that's preparing to launch a focus-free digital camera later this year.
The basic premise of Lytro's technology is pretty simple: The camera captures all the information it possibly can about the field of light in front of it. You then get a digital photo that is adjustable in an almost infinite number of ways. You can focus anywhere in the picture, change the light levels -- and presuming you're using a device with a 3-D ready screen -- even create a picture you can tilt and shift in three dimensions. (I got a demonstration of the camera's 3-D photos on a laptop and was blown away.)
You might think that this would produce unfeasibly large digital files, but Ng insists that the files will be roughly comparable to the average size of a digital photo today. The heavy lifting is being done by the camera's on-board processors, he says. And because its light sensor is incredibly sensitive, you can capture low-light situations such as in restaurants a lot more easily -- even without the flash.
Although the camera itself isn't due out until late 2011, Lytro on Tuesday unveiled a carousel of demonstration snapshots -- all of them embeddable, available in Flash for the Web and HTML5 for your smartphone. Here's an example. Click anywhere on the picture to change the focus, double-click to zoom.

Remind you of Instagram's tilt-shift feature, perhaps? Sure -- except when you realize that Instagram can only focus on one area of the screen at a time. See how the chain link fence snaps in and out of focus? That's how you know it's a picture with a whole lot of light field information in it.
And the cost of this camera? Ng says it will be comparable to other consumer-priced digital cameras on the market. If the end result is anything like these demonstration photos, the $40 billion camera market is about to meet a whole lot of disruption.
