Javascript convert color image to black and white

I need a html file has following features:

- Allow user select an image file at client.

- Convert the color image file to Black & White, and display it on the screen (like preview).

- User click Submit, post the black and white image will be posted to server (similar to Upload), so that at server side, we can use the server script to work with the image.

Prefer to use: HTML5, Javascript. If you use any extra javascript libarry, please define clearly.

I expect the size of black and white image is at least 50% of color image.

The input color image will be picture of text and paper.
