You can use HSV model to calculate the values, where H is Hue, S is saturation and V is value( or brightness)

Here RGB are the Red, Green and Blue value of pixel which I am assuming you are able to read with help of some image processing library.

This might be difficult to implement using only native Java libraries, however you might be interested in some 3rd party library like for example ImageJ which enables you to control contrast, brigthness and so on. There are also a couple of examples on the aformentioned page.
