Class JavaCameraView

java.lang.Object
  SurfaceView
      org.opencv.android.CameraBridgeViewBase
          org.opencv.android.JavaCameraView

public class JavaCameraView
extends CameraBridgeViewBase
extends CameraBridgeViewBase

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.

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()
