ABSTRACT

A cinema screen is a highly reflective surface and the audience watch the giant projected images in a darkened auditorium. A television set is a small light box that emits its picture usually into a well-lit room often provided by high intensity daylight. The initial brightness ratio between black and white tones of a subject before a video camera often exceeds the dynamic range of any display monitor. This problem is exacerbated (because of the regulations imposed on the design of the transmission path), by a lower contrast ratio handling ability than is theoretically possible and because television is viewed in less than favourable lighting conditions.
