Class NativeCameraView

java.lang.Object
  extended by SurfaceView
      extended by org.opencv.android.CameraBridgeViewBase
          extended by org.opencv.android.NativeCameraView

public class NativeCameraView
extends CameraBridgeViewBase

This class is an implementation of a bridge between SurfaceView and native OpenCV camera. Due to the big amount of work done, by the base class this child is only responsible for creating camera, destroying camera and delivering frames while camera is enabled

connectCamera

protected boolean connectCamera(int width,
                                int height)
Description copied from class: CameraBridgeViewBase
This method is invoked shall perform concrete operation to initialize the camera. CONTRACT: as a result of this method variables mFrameWidth and mFrameHeight MUST be initialized with the size of the Camera frames that will be delivered to external processor.

Specified by:
connectCamera in class CameraBridgeViewBase
Parameters:
width - - the width of this SurfaceView
height - - the height of this SurfaceView

disconnectCamera

protected void disconnectCamera()
Description copied from class: CameraBridgeViewBase
Disconnects and release the particular camera object being connected to this surface view. Called when syncObject lock is held

Specified by:
disconnectCamera in class CameraBridgeViewBase
