Your comment is somewhat misleading. The 808, while a great high resolution sensor, processed stills at 5MP after pixel binning, compared to the 48/24/12MP of the iPhones. It did have a non-binned mode but again for stills. https://en.wikipedia.org/wiki/Nokia_808_PureView https://en.wikipedia.org/wiki/Nokia_808_PureView The majority of the post is actually about video and the comparison is a lot more dramatic there. A 4k frame from a modern phone ,like the iPhone 16 pro, is ~8MP. The 808 could “only” do 1080p at 30fps (62M pixels a second). Compare that to 4k at 120fps (995M pixels a second). That’s a far cry from 1Bn per second that you’re claiming. Impressive for the time though. There’s a significant difference here. The sensor on the 808 was amazing. The real meat of the tech here is the image processing pipeline that can process everything off the sensor for further processing.

The issue is not what Nokia did with it, but the presence of the functionality. The binning and other features were enabled (poorly or not isn’t part of the discussion) by a chip that could do about 1 billion pixels per second; that’s the issue; Apple doing it 12 years later and hyping it is what I was commenting on.

  No, the issue is that you’re misrepresenting the facts of the device. The processing you’re talking about could not handle 1Bn pixels a second except for maybe the very frontend of the pipeline. It could not handle it beyond that, which is where the meat of any ISP is. It’s easy to dismiss the technology if you allow yourself to dismiss the majority of what needs to be done past the sensor read out.

    It's the Broadcom BCM2763, also known as the VideoCore IV. The datasheet is still available. This is happening well beyond the sensor read-out and the fact you are mentioning that, tells me you don't actually understand the architecture at the necessary level. Sorry.

      Again, because you continuously ignore the issue of the rest of the processing pipeline to be convenient to yourself, tells me you don’t have a reasoned argument. Sorry.
