I am doing a project to read the data on a calculator screen via image processing. I need to make the image binary in such a way that only the digits in the image appear black and the rest is white. Can I do it with any image enhancement tool? Please suggest. Can somebody do it for me?

use 'histeq' function for enhancement or use 'adapthisteq' by choosing proper clipping range.
After applying this method convert to binary.

See my answer to your duplicate question. I got the numbers out of there using color segmentation and some standard image processing to clean up some noise. I didn't even have to do background correction. You should not accept an answer if it didn't answer your question.
