How to scan image in Delphi?

How would I scan an image into my computer while having the background a solid color?

• I am trying to scan some images into my computer that I have hand drawn for a video game that I am making. The drawn image is on a plain white sheet of paper, but every time I scan it into my computer, the areas of the paper where the image is not drawn is like 50 different shades of white, since paper isn't a solid white, my question is, how could I scan the images into my computer so the background is 1 solid color so I can use MSpaint to fill the entire background easily? Or does anyone have any ideas on how I could change the background to one solid color without having to erase the entire background by hand?
