      Hello Mr Young;

      You mentioned - debayer- in one of your posts, (of course it's from years ago) do you think this method have compatible enough with 3_chip processing?
      In fact, is there a special advantage in 3-sensor cameras? Considering that with the advancement of sensors, the difference has become imperceptible.

      And another question about the first generation bmpcc small camera (with a one-inch sensor), do you think this camera used a bayer filter, or a three-layer filter technology? I will be very happy to hear your opinions in any case

      I also invite you, if possible, to join our post, comparing two Sony cameras.

      Thank you

        All single sensor CMOS cameras need their images to be Demosaiced. Three sensor cameras don't as they have a full complement of R, G & B pixels on each sensor. Most single sensors have 50% green photosites, and 25% red and blue, respectively. In the process of Debayering the missing 50% of green and the missing 75% from the red and blue channels has to be reconstructed from an algorithm. Depending on the algorithm, it is generally accepted by sensor designers that this process involves around about a 20%-25% loss in resolution. Example, most 4K photosite cameras really only have a resolution of 3K plus, not 4K. One of the exceptions to this rule of thumb was the sensor in the Sony F65. A 4K camera but with an 8K sesor. Good sensor info found at the last link below.


        Sigma have tried for years to develop their three layer RGB Foveon sensor to a degree where it can compete favorably with single sensor Bayor sensors. So far not too much luck. Three sensor cameras are inherently more sensitive, given that you are comparing sensors of the same size. See links below.
