Silicon Valley start-up Lytro has unveiled a curious looking camera which allows users to click photos and focus later.
The Lytro camera, which will be available for $399 from Lytro's website, allows users to click an image and decide which objects to focus on later. This has been made possible using the light-field photography.
In traditional cameras, during in-focus shots, light from only on direction is focused on the image sensor, in order to make the image sharp, c|net explains. However, using the light-field photography technology, light from all directions is focused on the image sensor, rendering a 3D map of the object that was photographed using the camera, allowing people to focus on any object in the image they want later.
The camera has been designed as 4.4 inch long box and comes in three colours, with the blue and graphite versions carrying 8GB of built in memory while the red coloured version carrying 16 GB of storage. The device has a lens at one end and a touch screen display at the other.
"Light field photography was once only possible with 100 cameras tethered to a supercomputer in a lab," said Lytro's CEO and Founder Dr. Ren Ng. "Today it's accessible to everyone in a camera that's small and powerful, but incredibly easy to use. Our goal is to forever change the way people take and experience pictures, and today marks our first major step," he added.
