Digital TV Better for Eyes - Harvard Study
[Edit]
[Edit]
Change is good. Forced change by the government can be good too. One of the unanticipated spins off of switching TV signals go all digital is the possibility of enhancing the image for people with poor vision. At Harvard Medical School, Dr. Eli Peli, is working on such a project. The development involves changing the contrast on the television signal. Over 4 million Americans suffer from macular degeneration which makes seeing reading or seeing fine details difficult, and makes watching television nearly impossible.  Working within the "decoder" that makes digital television images possible, Peli and his colleagues were able to make a simple change that could give every digital TV the contrast enhancing potential for the benefit of the visually impaired. "The same modification could easily be made to new HDTVs, and digital cable set top boxes," says Matthew Fullerton, the paper's first author, and a student of electronic engineering from the University of York in England who is currently working on his Master's degree in Peli's lab.
