This arrangement makes the chip particularly suitable for image-processing, because each analogue element of the array can be made to correspond to a single pixel (one of the individual dots of which an image is composed).

ECONOMIST: Analogue computing

When combined with a suitable light source and projection optics, the array of mirrors can project an image.

ECONOMIST: Curtains for celluloid

An array of field-emission devices, however, will take their exposures simultaneously, so the resulting image should always be pin sharp.

ECONOMIST: Modern X-ray technology

There's an array of new camera effects, such as one where you can superimpose for fun a small square image of your own face onto a picture you're taking, and another where you can create a "Drama" shot in which a single moving person appears multiple times in sequence.
