Kodak Image Sensor Solutions has today announced a new Color Filter Array (CFA) layout (and image processing path) as an alternative to the widely used Bayer pattern which should provide higher sensitivity. This new layout features one 'panchromatic pixel' (monochrome) to every colored pixel (red, green or blue) and there are three proposed layouts. Kodak ISS are presenting this as a technology solution which can be applied to any size, megapixel count or type (CCD / CMOS) of sensor. Kodak claim a one to two stop improvement in sensitivity, the tradeoff is of course color resolution which is effectively a quarter of the traditional Bayer pattern. This interesting development will of course only be proven when we see it actually implemented and we can compare it to traditional Bayer.
