Abstract
The subject is introduced by a brief reference to the general principles of television, and the work which has already been done in the photographic and cinematographic field to establish the requirements of a “good picture.”
The main treatment deals with the practical limitations to the realisation of the ideal picture imposed by the characteristics of the television system. Picture contrast, range, brightness, definition, size, presentation, colour or tint, and flicker are dealt with. New and accurate methods of measurement of these characteristics are described, and results given.
Cathode ray tube receivers are generally dealt with, but the results are considered to be applicable to other methods of Television reception.
Finally reference is made to possible future developments in television picture reproduction.
