The goal of a captcha is not like a password. A password must be case sensitive to increase the number of combination. There is not need to be case sensitive for a captchca.
Goal of a captcha is to force the system that submit the form to prove it is not a robot and that he was able to understand "humanly" the captcha. And proving that analysis of image was done by a human does not need to use case sensitive information when submitting the value, the value itself is enough (we don’t mind the number of possible combination for that, this is the goal of password). Think to the captcha of google that is the “Do you see a car on image ?”. We don’t mind if the answer if “Yes” or “yes”, all thing we need is to get yes or no.
