          extended by org.opencv.android.CameraBridgeViewBase
              extended by org.opencv.android.JavaCameraView
All Implemented Interfaces:
android.graphics.drawable.Drawable.Callback, android.hardware.Camera.PreviewCallback, android.view.accessibility.AccessibilityEventSource, android.view.KeyEvent.Callback, android.view.SurfaceHolder.Callback

public class JavaCameraView
extends CameraBridgeViewBase
implements android.hardware.Camera.PreviewCallback

This class is an implementation of the Bridge View between OpenCV and Java Camera. This class relays on the functionality available in base class and only implements required functions: connectCamera - opens Java camera and sets the PreviewCallback to be delivered. disconnectCamera - closes the camera and stops preview. When frame is delivered via callback from Camera - it processed via OpenCV to be converted to RGBA32 and then passed to the external callback for modifications if required.
