示例1: createCameraSource

 * to other detection examples to enable the barcode detector to detect small barcodes
 * at long distances.
 */
private void createCameraSource() {
  mCameraSource = open();
  maxFace = mCameraSource.getParameters().getMaxNumDetectedFaces();
  if (maxFace == 0)
    maxFace = 10;
  //mCameraSource.setFaceDetectionListener(this);
  previewSize = mCameraSource.getParameters().getPreviewSize();
