Hello
New AI desktop applications are expected to allow more efficient HR image reconstruction from Quad-bayer sensors than possible in the phone. Could Open Camera retrieve a full size "raw" file (without pixel binning) in order to test these applications. Thanks

❛full size "raw" file (without pixel binning)❜
Open camera provides exactly such RAW files. The "pixel binning" is purely a marketing hoax, on which the untruthful 50MP ... 200MP pixel resolutions are falsely marketed.
The truthful output resolution is 12MP for all the current "quad-bayer" sensors (currently 48MP to 200MP). There are more light sensitive sites on the quad chip than the 12 million, the photons that they count are being combined to form those 12MP, this is done in order to improve yield in chip manufacturing. A tiny impurity particle on a pixel site renders the whole pixel faulty. When that pixel site is divided into 4 or 9 sub-sites, then the tiny impurity particle renders only one sub-site faulty. There are many ways to to filter out the failing sub-sites.
This quad-hoax is severely detrimental to image quality, but then it allows the poor and uninformed to buy a "50MP" ... "200MP" at the price of a bottle of good wine. Just look at the devices that de facto have better image quality, such as iPhone and high end Sony devices, they are all equipped with a honest 12MP sensor ... at a price.

There is the benefit of dual exposure modes in quad bayer sensors.

The dual exposure only only doubles the already bad amount of noise level of the photos.

The other benefit could be "super pixels", as the pixels are so tiny.. way smaller what these lenses can resolve. You could then collapse 4 pixels into one, with full RGGB values and having finer microcontrast & color detail than regular bayer sensors. So in theory, quad bayer sensor do enable more flexibility. But sadly the sales pitch is 100mp :) And that's impossible for any smartphone lens, reality lies in the 8-12mp range.

I perfectly respect your wish not to use full size sensor result. Please allow informed people to experiment.

It looks like Android 12 has added support for full quad bayer resolutions, it's on my TODO to look at this.
Thanks
