捕获图像并在android中显示相同的活动 - 图像预览模糊

Question

我正在开发一个代码来捕获图像，然后在预览模式下显示它。捕获图像工作正常。但是在活动中显示它时，我将图像视为模糊图像。可以请有人对可能的解决方案有所了解吗？ （请参阅下面的代码）

PreviewImageActivity.java

    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        setContentView(R.layout.image_capture);

        cam_button = (ImageView) findViewById(R.id.button1);
    }

public void captureclick(View v) {
            Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
            startActivityForResult(cameraIntent, CAMERA_REQUEST);

    }

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        if (resultCode == RESULT_OK) {
            // user is returning from capturing an image using the camera

            if (requestCode == CAMERA_REQUEST) {
                Bitmap captured = (Bitmap) data.getExtras().get("data");
                AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(context);
                alertDialogBuilder.setTitle("Image Details");
                alertDialogBuilder.setMessage("Height: " + thePic.getHeight() + "Width: " + thePic.getWidth()).setCancelable(false).setPositiveButton("OK", new DialogInterface.OnClickListener() {
                    public void onClick(DialogInterface dialog, int id) {
                        dialog.cancel();
                    }
                }).setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
                        public void onClick(DialogInterface dialog, int id) {
                            dialog.cancel();
                        }
                });

                AlertDialog alertDialog = alertDialogBuilder.create();
                alertDialog.show();

                setContentView(R.layout.activity_full_screen);
            full_img = (ImageView) findViewById(R.id.full_image);
                full_img.setImageBitmap(captured);

}

image_capture.xml

<ImageView
    android:id="@+id/button1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_below="@+id/textView1"
    android:layout_centerHorizontal="true"
    android:layout_marginTop="20dp"
    android:onClick="captureclick"
    android:src="@drawable/camera_icon"
    android:text="@string/Click" />

activity_full_screen.xml

<ImageView
    android:id="@+id/full_image"
    android:layout_width="match_parent"
    android:layout_height="match_parent" 
    android:contentDescription="@string/full_image_desc" />
