I've never heard of this Darbee Darblet thing. Quite frankly I'm skeptical of the companies claims. How can you improve upon a picture that comes from the original source? In addition that wouldn't the electronics add "noise" to the picture? This is similar to the claims of sound processors years ago, sure you could alter the sound but in the process introduced floor noise into the sound; same with the Bose surround sound processor they had, it introduced noise into the sound, same with sound shapers . BUT, having never used this Darbee Darblet I could be completely wrong, but my past experience with such devices indicates otherwise.
