Trying to obtain an RGB image

edit

Hi,

I am finding trouble in viewing the image on '/camera/image' topic. A blank screen comes up when I use the following command.

rosrun image_view image_view image:=/camera/image

But when I try to look on topic /camera/image_raw I get a monochrome image. When I try /camera/image_color topic, I get a green shaded image. I would like to get and normal (rgb )image , I see only the following topics :

/camera/camera_info

/camera/camera_nodelet/parameter_descriptions

/camera/camera_nodelet/parameter_updates

/camera/camera_nodelet_manager/bond

/camera/image

/camera/image_color

/camera/image_mono

/camera/image_proc_debayer/parameter_descriptions

/camera/image_proc_debayer/parameter_updates

/camera/image_raw

/diagnostics

/image_view_1467243696220883524/parameter_descriptions

/image_view_1467243696220883524/parameter_updates

/rosout

/rosout_agg

Can I know how can I get normal RGB image ?

Thanks in advance.
