2Android Camera2Raw Sample
3===================================
4
5This sample demonstrates using the Camera2 API to capture a JPEG and RAW sensor frame.
6Check the source code to see a typical example of how to display the camera preview;
7run auto-focus, auto-exposure metering, and auto-white-balance; capture a JPEG and
8RAW image for the same sensor frame; and save these into MediaStore for use in other
9applications.

11Introduction
12------------
13
14The [Camera2 API][1] allows users to capture RAW images, i.e. unprocessed pixel data
15directly from the camera sensor that has not yet been converted into a format and
16colorspace typically used for displaying and storing images viewed by humans.  The
17[DngCreator][2] class is provided as part of the Camera2 API as a utility for saving
18RAW images as DNG files.
19
20This sample displays a live camera preview in a TextureView, and saves JPEG and DNG
21file for each image captured.
