problem on running image_view node

Hi all, I installed the package ros-groovy-camera-umd, after this I run a launch file like this

<launch>
  <node ns="camera" pkg="uvc_camera" type="camera_node" name="uvc_camera" output="screen">
    <param name="width" type="int" value="640" />
    <param name="height" type="int" value="480" />
    <param name="fps" type="int" value="30" />
    <param name="frame" type="string" value="webcam" />
    <param name="device" type="string" value="/dev/video0" />
  </node>
</launch>

The device path I have already checked where it is connected and if the camera is responding.

After running the launch file I get this response:

unable to open camera calibration file ["path"/camera.yml] 
Camera calibration file "path"/camera.yml not found 
I only handle discrete frame intervals… 
I only handle discrete frame intervals… 
I only handle discrete frame intervals…

…

Then I try to look at the topic /camera/image_raw

rosrun image_view image_view image:=/camera/image_raw

And I get no response from the camera
