A few days back, we collectively trolled Leica for making Black and white cameras. However 2 days ago, while doing so googling for my blog post, I came across an amazing technology used in Leica M Monochrome camera - Non Bayer sensor
Conventional cameras even the high ends like D800E and 1DX use a Bayer sensor. Just for example a conventional Bayer MP sensor includes only 4Mp green, 2Mp red and 2Mp blue pixels, which are interpolated to 8Mpix R, G, B image.
A similar non bayer sensor uses true R, G, and B pixels. Advantage? Bayer matrix results in loss of 30-50% of the real resolving power of the sensor.
Although I lost the blog link, the 18MP images from Leica had equal or in some images had greater details than the 36MP images from D800E.
Interestingly Nokia 808 also uses oversampling to eliminate Bayer interpolation hence its 5MP images are very very detailed. But in most cases are under 2MB. Hence we get the resolution equivalent of 10-12MP images in a very small size. This is some amazing technology!
