Default Jelly Bean AOKP camera/image quality worse?

Hi,

I decided to try out some JB betas in advance of the proper OS being put out by Samsung. I've flashed a couple different AOKP based JB ROMs now and on both, compared to my previous ROM, which was a modified Samsung ICS ROM, the camera seems worse. In particular, the white balance seems off, colours are not as punchy and look washed out, the 'shutter' seems slower and more pictures are coming out blurry, and images not in full daylight look more grainy. And even more bizarrely, I've pointed it at a white/neutral sheet and a pinkish spot appears in the centre of image.

Anyone else experience this? Generally most of my SGS2 shots used to come out good and it was replacing my point and shoot. Now, they sort of look like they came from a camera phone if you know what i mean.

I'm wondering if the software algorithms for image processing come with the ROM or kernel (JB came with the latest Siyah)? Is it possible that the official Samsung ICS software is optimized for the SGS2 hardware, whereas these JB betas are cobbled together from various sources? I don't know at what hardware/software level these things are processed.

thanks!

Camera drivers are almost always proprietary.

AOSP pictures and camera software is always going to be a little worse than the manufacturers

Thanks. So where does the driver live? Is it a separate file that one can pull out of the sammy ROM and push into the JB one?

No, its proprietary code so you'll never quite get it to work on aosp.

Devs have to reverse engineer it to get the camera working in the first place

Thanks for explaining. I knew that you wouldn't find non-open source code being distributed freely, but thought the system would be more modular than that. I need to learn more about linux....

Oh well, back on ICS and enjoying my camera again, and patiently waiting for the official JB upgrade.
