"Most of us take seeing the television for granted," says Dr. Eli Peli, principal investigator of the study, senior scientist at SERI and a professor at Harvard Medical School. "But for the visually impaired, it is very difficult. This is a source of great frustration and discouragement since so much news and entertainment come from tuning into the 'tube'."
As a low vision rehabilitation expert, Peli sees hundreds of patients suffering from vision impairments caused by diseases such as age-related macular degeneration (AMD), diabetic retinopathy and other diseases that impair the central vision. AMD destroys the tiny central part of the retina called the macula. This makes activities such as reading, driving, and watching television extremely difficult. Peli, an electrical engineer and an optometrist by training, has devoted his career to creating and evaluating new technologies to help low-vision patients regain their ability to do these tasks.
The goal of the current OPO study was to determine if people with impaired vision benefited from an individually tuned contrast enhancement of their TV.
Peli and his colleagues used an image-processing device developed for them by DigiVision Inc. that allows them to manipulate, in real time, the contrast of different sized details (or edges) in the video screen to their individual liking. "This is a very flexi
