Abstract: Video research for the human viewer begins with research on how a human being perceives a moving image. The research includes studies on how the eye processes images with different parameters such as brightness, contrast, distance from the eye and resolution. Coupled with these studies is research on how the human brain processes more complex stimuli. For example some questions that can be asked are: What is the effect of the visual persistence?; How is motion treated?; And what is the effect of size and brightness on how the the brain treats the information about the image. The results of this research are crucially important to questions such as: What is the best picture that can be displayed through a channel of a given restricted bandwidth?; What is the best display for a given cost?; What is the optimum frame rate? And how is motion best treated?. Research at the RCA Laboratories includes the total system which brings the video image to the human viewer. The goal is to develop metrics which can be used to compare system tradeoffs. The research includes hardware and software system simulation as well as study of the human viewer. The research programs and some of the pertinent results will be presented.

bio
Jon Clemens received a Ph.D. degree from MIT in September 1965. His thesis work was on optical character recognition. He joined RCA Laboratories in 1965 to work in consumer electronics research. Most of his technical work has been concentrated on consumer video products. In 1983 he was appointed staff vice president, consumer electronics research at RCA Laboratories, and he presently fills that position. In this capacity he is in charge of consumer electronics research for the RCA Corp. He has three research laboratories reporting to him: Television Research Laboratory, Digital Products Research Laboratory, and Information Research Laboratory. Jon has received three RCA Laboratories Outstanding Achievement Awards and the David Sarnoff Award for Outstanding Technical Achievement, RCA's highest technical honor. He was a corecipient of the 1980 Eduard Rhine Prize, presented by the Eduard Rhine Foundation of West Germany, for major improvements in television systems and a corecipient of the IEEE Vladimir K. Zworykin Award in 1983.
