RGB conversion. The camera subsystem outputs YUV images naturally, while the GPU
and display subsystems generally only accept RGB data. Therefore, after the images are
fused/composited, a standard YUV->RGB color transform is applied before the the data is written
to the output Allocation. The HDR fusion algorithm is very simple, and tends to result in
lower-contrast scenes, but has very few artifacts and can run very fast.
Data is passed between the subsystems (camera, RenderScript, and display) using the
Android [android.view.Surface][1] class, which allows for zero-copy transport of large
buffers between processes and subsystems.
