Researchers invent 'new type of pixel' that could create displays that double as cameras — and the internet's first thought is 'what could go wrong?'

Fourier pixel.

• A new type of pixel is capable of both controlling and analyzing light
• It's based on the Fourier mathematical tool
• We'll have to wait some time to get this in our gadget screens

Screens that double up as cameras could be packed into future gadgets, as researchers from ETH Zurich in Switzerland have developed a new type of pixel that can analyze and create images simultaneously.
