If you like to measure your cell phone in megapixels, listen up. Sony has just unveiled a 16.41 megapixel, back-illuminated sensor for mobile devices. The 1/2.8-inch thick, color-sensing beast — officially known as the Exmor R IMX081PQ — will be available to manufacturers this coming January and will carry a $30.30 price tag. Sony also announced a more modest 8.13 megapixel sensor that will retail for $18.18.
