Mediatek Dimensity 9000 Supports 320MP Sensors

TalkAndroidGSMArena: Mediatek presents a 4nm Dimensity 9000 application processor for future smartphones with quite impressive imaging features:


  1. Can someone explain the technical motivation of a 100+mp, 0.x um pixel cis in a smartphone? Advanced/large optics in machine vision have a hard time to really utilize 2 um magnitude pixels, i doubt smartphone optics do better (i have to admit, the cameras in smartphones work surprisingly well). how many line pairs can such smartphone optics resolve? I see people buy it, then share 99% the images on social media where they get downscaled to what? 0.5MP? How much of this 100s MP is technically justified and how much of it is for marketing reasons?

  2. 99% marketing. The 1% technical is the reduced burden on the Bayer demosaicing algorithm.

    Marketing plays indeed a very important role. But defect correction becomes much easier if you have more pixels, and the perceived (!) signal-to-noise ratio is also becoming better if you have more pixels.
    When we (= Philips) introduced 6M pixel devices with large pixels, the customers told us : "we love the large pixel because it gives us a huge dynamic range, but what shall we do with 6M pixels ? This is really an overkill !"
    I do have to admit that I am talking about 20 ... 25 years ago. But nevertheless ...
    On the other hand, here Mediatek announces their support up to 320M pixels. By the year 2025 this no longer will be enough, that's for sure. Never a dull moment (Rod Stewart) in imaging !
