I unzipped a 4.3 ROM and found there's a "cameradata" folder with 8.7mb of files in the systerm folder, which is separate from the "SamsungCamera2" APK. I can try loading an AOSP ROM, installing the APK, and placing the cameradata folder in the system folder. How do I install the APK? Would i need to put in the system/app folder then install via settings? Of course I'd make a Nandroid of my current ROM first.
The short version is simply no.
The long version is...
The issue with the camera in AOSP ROMS is that the stock TouchWiz camera has all kinds of proprietary software driving it. That software is built into different parts of the rom and absolutely requires the TouchWiz framework to run. (Which is also proprietary). You can't just pull the APK out of TouchWiz and install it on AOSP.
So there is no way to get the stock TW camera to run on any AOSP rom.
This means that any other app that is using the camera is using generic software to run the camera hardware. This leaves out the ability to do things that the TW software was specifically written to do like crisp auto focus and color depth and all those goodies that make the TW camera better. All that software was written specificly for the S4 hardware.
The Cyanogen camera or the Google stock camera is just an app using generic software not written specificly for this phone's camera hardware. That's no different than ANY other camera you can find on Google Play. They are ALL using generic software.
As a result, none of them are every going to be as crisp as the TouchWiz camera software. They almost all still take a really good picture with this phone, and many give various effects you might enjoy, but if you are looking for a downloadable camera app that takes a higher resolution, better focused picture than the CM camera, you're not going to find one that's substantially better.
It's the major drawback of AOSP roms on the S4. But unless you are a photog with a really decerning eye, you will eventually become used to the AOSP Camera quality. It's still better than most other phones on the market.
