Video Research for the Human Viewer

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.
