A Television Image Simulator and Its Practical Applications
Rostyslav Shavlach · Optical Engineering · 1964
The television signal resulting from the scanning of an image (such as a photographic transparency) can be processed to achieve interesting and useful effects. Among these effects are variation in resolution and noise, variation of the contrast ratio within any specific range of the gray scale, control of differentiation for bas-relief effects, and production of an equal-brightness contour. Included are the descriptions of the methods of producing the effects and the results attained. Photographs illustrating the various processes are shown to demonstrate the results.
