Android HdrViewfinder Sample
This demo implements a real-time high-dynamic-range camera viewfinder, by alternating the sensor's exposure time between two exposure values on even and odd frames, and then compositing together the latest two frames whenever a new frame is captured.
RenderScript,1080P的图像用ScriptIntrinsicYuvToRGB大约6ms左右。
相对GL shader而言开更easy
