If, like most users of compact digital cameras, you're sick of their shabby performance in anything other than bright sunlight, then please stand and applaud a new kind of sensor that will make low-light woes a thing of the past.
Fed up with old CCD and CMOS sensors, Japan's Rohm and National Institute of Advanced Industrial Science and Technology got together to build a better image sensor. The result is 100 times more sensitive than what has gone before.
Low-lux performance
As the illustration shows, the CIGS sensor produces images in what appears like total darkness to a CMOS device. The combination of Copper, Indium, Gallium and Selenium remains functional as low as 0.001 lux. By way of comparison, moonlight is rated at around 1 lux.
The next steps for the two organisations are to miniaturise the sensor and to stabilise production standards to prepare for commercialisation.
