------ Solution ----------------------------------- ---------
final void setPreviewCallback (Camera.PreviewCallback cb)
Installs a callback to be invoked for every preview frame in addition to displaying them on the screen.

abstract void onPreviewFrame (byte [] data, Camera camera)
Called as preview frames are displayed.

here to return to the preview frame rate quickly, data as a YUV data stream needs to be converted to RGB add a good timing, you can get the effect you want.
