The Bayer array places color filters in a regular four-pixel pattern over the pixels of an imaging sensor. After the image is captured, the colors in the resulting digital image are interpolated and applied to the image. Panasonic seems to have figured out a way to precisely disperse the colored light that comes out of their micro color splitters so that they can apply a similar type of interpolation on the images captured by their new system. The filters employed in the Bayer (and X-Trans) method consume a substantial amount of light before it reaches the sensor, so there's a potential for improvement in terms of sensitivity. The new Panasonic method claims to pass the vast majority of that light through to the sensor. The difference is demonstrated below.
