1 2 Android Camera2Raw Sample 3 =================================== 4 5 This sample demonstrates using the Camera2 API to capture a JPEG and RAW sensor frame. 6 Check the source code to see a typical example of how to display the camera preview; 7 run auto-focus, auto-exposure metering, and auto-white-balance; capture a JPEG and 8 RAW image for the same sensor frame; and save these into MediaStore for use in other 9 applications. 10 11 Introduction 12 ------------ 13 14 The [Camera2 API][1] allows users to capture RAW images, i.e. unprocessed pixel data 15 directly from the camera sensor that has not yet been converted into a format and 16 colorspace 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 18 RAW images as DNG files. 19 20 This sample displays a live camera preview in a TextureView, and saves JPEG and DNG 21 file for each image captured. 22 23 [1]: https://developer.android.com/reference/android/hardware/camera2/package-summary.html 24 [2]: https://developer.android.com/reference/android/hardware/camera2/DngCreator.html 25 26 Pre-requisites 27 -------------- 28 29 - Android SDK 25 30 - Android Build Tools v25.0.3 31 - Android Support Repository 32 33 Screenshots 34 ------------- 35 36 <img src="screenshots/main.png" height="400" alt="Screenshot"/> 37 38 Getting Started 39 --------------- 40 41 This sample uses the Gradle build system.
