Hi-tech camera lets you 'frame' shots using your fingers - and you 'zoom in' by moving it away from your face

  '**Frame' of fingers works like a viewfinder

Many amateur photographers have held up a 'square' of fingers to frame a shot before taking it - now a Japanese camera uses that same 'frame' as a viewfinder. 

The camera takes the form of a box that fits on a finger, and making a 'square' of digits above it works as a viewfinder.

A motion-sensitive 'zoom' lets you move in to the action by moving the camera closer to your face.

Camera users fit the tiny square camera unit over a finger, then 'frame' shots using their fingers

The 'square' of fingers work as a viewfinder for the prototype, which was demonstrated at a Japanese technology institute

In the demonstration, users could also see their 'viewfinder' mirrored on a nearby computer screen
'When you take a photo with your face close to the camera, you get a wide-angle shot,' says the team. 

'If you move it further away, it zooms in and you get a close-up shot.' 

The camera was shown off by students at Institute of Advanced Media Arts and Sciences, a public university in Japan.

The prototype is some way off commercial use, however. 

The proximity sensor it uses is infrared, so the prototype won't work in sunlight. The information is processed in a PC, not in the camera itself, so the current prototype has to be 'tethered' to the PC.

If the camera is to become a commercial reality, the team will have to move the image-processing into the unit itself - which could mean a finger-twisting effort to hold a camera while making a 'frame' with fingers at the same time.
