New camera sensor allows refocusing after the shot.
A new sensor module from Toshiba uses an array of 50,000 tiny lenses inside a 1cm thick unit, which allows photos to be refocused after the shot is taken. Although Lytro offers similar technology in their ‘light field’ cameras already, the Toshiba module is small enough to fit in a smartphone or tablet, and can perform the same function on videos, features which Lytro can not yet manage.

The company says the technology is still in development, although they hope to have it commercialized before the end of 2013, after which it will hopefully be picked up by multiple smartphone and tablet makers.
