It looks like Google will be finally working on improving their most neglected feature in Android, the camera software. First, a developer named Josh Brown noticed in some Android code that Google is working on a new Android camera API. This new API would allow the camera to store RAW (uncompressed) images along with the JPEG ones. This would provide users with a massive amount of correction and manipulation capabilities after the image is captured. It looks like the new API might also get some stock support for modular and external cameras, which would be rather unusual.

That's not all. Here's a quote with more of the details,

The new API also supports face detection. This includes bounding boxes around faces and center coordinates for the eyes and mouth. In addition to the face-focus capabilities, the system can assign unique IDs to each face (provided they stay on screen) so developers could do things like assign silly hats to multiple faces in a video feed. While you may have seen face detection on some Android devices, those were all solutions built by Android OEMs.

There's support for burst mode, too—another feature that you would swear was already included in Android, but isn't. On Nexus devices, the only "burst mode" involves the user pressing the shutter button really fast.
Finally, there are also hints in the code that Google is working on improving the image quality and "fine-grain control" in the camera capabilities on Android. Supposedly this new API work was started in December of 2012, so it's possible we might see it show up in a later version of KitKat. It's exciting to see Google finally paying attention to one of the most important aspects of a smartphone.
