> I think you are confusing two terms. Downsampling and pixel binning. But we mean the same thing: pixel merging. I meant interpolation rather than extrapolation.

This is a very simple approach. It’s a little more complicated. https://crast.net/12421/w…-your-mobile-photography/

> But apart from that, my point still stands. If you want 12MP photos, just get a 12MP sensor. Then you don’t have to minify the sample and end up with the same result (of course you can also version post-processing on both).

no mistake. This is not how it works. Again, more data is better for CP. More “pixels” is more data to cost. You can get more data and capture more light. So, it’s a perfect combination that can’t do with your incorrect claim.

> Leaving the “shutter” open longer doesn’t matter either. I understand you have more data then.

“Never mind. But you have more data.” So this is not true what you are saying.

> And for example, you can take fewer and more exposed photos for the HDR app. And many more tricks. But even then, you have nothing to do with 200MP.

So it is important, because more data. Even then, you can benefit from 200MP, because you have more data than the CP. You also get a 2x optical zoom.

> The information it collects is very unreliable (due to the ultra-small pixels and limitations of the lens).

So that doesn’t matter. All of that data makes up for these negatives. So it doesn’t matter what pixels are so small, after all, 16 of them become a super pixel.

> You can do all this AI and other post-processing with a clean 20MP photo.

it does not make sense. 1.67x pixel binning is not used by anyone for reasons. Again, more pixels is better for CP and the end result.

Therefore, binning also provides more data for CP. Without the smallest “pixel” defects on the sensor.
