Scientists at Bell Labs have built a prototype camera that uses no lens and a single-pixel sensor. This idea is based around a grid of small apertures that each direct light rays from different parts of the scene to the sensor, and can be opened and closed independently. The sensor makes a series of measurements with different combinations of open apertures, and uses this data to reconstruct the scene in front of the camera. No lens to focus the resultant image means infinite depth of field and low cost. Click through for more details and a link to the original research.

Fujifilm is looking to bring down the cost of touch-screen technology by harnessing materials and manufacturing expertise used in creating film emulsions. Touch-screens are quickly becoming the standard interface of nearly every piece of mobile technology. Currently these screens utilize the fairly rare metal, indium. Due to its rarity, indium is responsible for a significant portion in the cost of current touch-screen displays. Fujifilm hopes to use its long history with silver to bring down the cost of these displays and grab a piece of the ever expanding touch-screen market.(via Bloomberg)
US technology company Rambus has unveiled 'Binary Pixel' sensor technology, promising greatly expanded dynamic range for the small sensors used in devices such as smartphones. Current image sensors are unable to record light above a specific saturation point, which results in clipped highlights. Binary Pixel technology gets around this by recording when a pixel has received a certain amount of light, then resetting it and in effect restarting the exposure. The result is significantly expanded dynamic range from a single exposure.

Fujifilm has been granted a patent for an innovative organic-hybrid sensor technology. However, while interesting, it may not offer a compelling advantage over existing designs, according to sensor technologist Professor Eric Fossum. The company has recently been granted a patent for its work on a sensor that uses an organic (carbon-chemistry-based) material on top of silicon circuitry. Speculation about Fujifilm's forthcoming mirrorless camera has latched onto a technical paper the company published in late 2009, but both Fossum and the company say the work shows more promise for small-scale sensors.
