Abstract We have previously demonstrated improved face recognition by visually impaired persons (Peli et al., 1991, Invest. Ophthalmol.). Due to technical limitations, previous studies used still, monochrome (black and white) images. We are now able to apply the same adaptive enhancement algorithm in real time to color video movies. Preliminary questionnaire evaluation of patients' responses demonstrate objective appreciation of improved perception of information as facial details and expression, and usefulness. We have also connected the Horizon digital low vision magnifying device to obtain real-time enhancement of text scrolled across the screen. This combination enables testing of the previous reports (Lawton, 1989, Ophthalmology) of increased reading rate with image enhancement of text. A video tape will demonstrate the enhancement of color video movies as well as the enhancement of scanned text. The results of the questionnaire administered to 10 patients and plans for further evaluation will be discussed.
