Are there any filters that would make background image to be displayed as black-and-white?

What I mean, is this: i have a background image set via css using background: url(/image.png);

But now I need to apply a filter so that an image is shown as black-white only. Ideally, I would like to also apply opacity to it.

The effect I really trying to achieve is to have background image black/white and on hover over that span element the filter would be removed, revealing the color version.

And of cause it has to work in FF, Chrome, IE

Can someone help me?
