This is a brief excerpt from thePhoBlographer
Panasonic just published a press release in which the company states that it has patented a new sensor technology that effectively gains a stop of light sensitivity by doing away with the color filter. The idea is not new–in the past, people had their cameras modified to be monochrome only by taking away the color filter array. The same has been done with the Leica M Monochrom, which effectively boosted its base ISO from 160 to 320. However, Panasonic’s new technology doesn’t leave the camera ‘color blind’. Quite on the contrary.
Conventional ‘Bayer’ color filter array
The technology that Panasonic developed–or rather, is still in the process of developing–makes use of the inherent properties of the different wavelengths of light, and the way these can be refracted. Much like a prism that fans out the separate light wavelengths to the colors of the rainbow, Panasonic’s new technology diverts the different wavelengths of red, blue and green light to the corresponding pixels with the help of a special refractive material. To the effect of gaining a whole stop of light sensitivity that was previously lost due to the color filter swallowing half of the incoming light.
