Depends on the instrument. The WFC2 actually operates in the visual range (as well as the near infrared and the ultraviolet), so images from that camera are possibly close to what we'd actually see.. IF our eyes were sensitive enough anyway, exposure times on those images are probably measured in hours or days or something (though I'm not sure). But yeah there's computer stuff going on I'm sure, compressing the entire visual range of the camera (or picking a part of it) into our visual range.
