is a very flexible device, but also quite expensive and complex, and thus could not be brought to market easily," says Peli. Using this device and similar approaches, Peli and his team learned that certain details in an image that are too small will not be visible to someone with central vision loss even with the highest contrast. They also learned --through patients' responses—that the large details in an image were fully visible--even to visually impaired persons—without modification.

The current study had two parts. In the first part, 46 subjects with central vision loss were shown a series of still images and asked to find–-by moving a computer mouse on the table—a setting where the image was most visible. Moving the mouse in one direction changed the size of the detail to be enhanced, and moving it in the other changed the amount of contrast enhancement applied to those details.

Peli and his colleagues found that the patients did have individual preferences. Each patient repeatedly selected a preferred size and a specific level of contrast enhancement. They also found that patients who selected smaller details to be enhanced selected less contrast enhancement.

In the second part of the study, 20 of these patients were asked to watch a video from a PBS program and rank the quality of moving images every 10 seconds by moving a mouse up and down on a table in front of them. Every 10 seconds, the processing of the video changed, ranging from un-enhanced, to purposely blurred, to enhanced according to the subject's individual preference. Additionally some images were viewed at enhancement levels arbitrarily set to 4 different levels: smaller details enhanced with higher and with lowers contrast than the individual selection and larger details also at higher and at lower contrast.

Peli and his team found that patients liked the images that reflected their own individual settings for contrast and details better than the un-enhan
