Android camera preview and image processing experiments

This Android app shows the direct conversion from the Android camera preview format (YUV or NV21) to a color or grayscale bitmap. No jpg compression or YuvImage-object was used.

It is clearly visible that the conversion to grayscale ist faster than to color (RGB). With the grayscale image we can do some digital image processings in (nearly) realtime. Shown are changes in brightness and contrast.
Camera preview size is 480 x 320 pixels.

Device : Nexus 7 (2013)
filmed with Panasonic Lumix FS16

App created with Basic4Android 3.80 using API level 14
