MATLAB: I can’t click Adjust contrast in imtool?

Question

Hi, I imported a picture from my matlab workspace to the imtool. I want to adjust the contrast of the picture but I can't click the adjust contrast button. The situation is the same, no matter which picture I open, from workspace of directly from a file. Any idea what I'm missing?

Thanks, Rok

Your image is color. Sorry, but there's no capability to adjust brightness and contrast on a color image in imtool() like there is in Photoshop.
