Distorting the time axis: motion-compensated image processing in the studio
Giles Thomas · 1988
Recent advances in VLSI device technology and algorithm development have made it a practical proposition to consider the use of motion compensation techniques in broadcast quality image processing. Such techniques offer the hope of significantly improved picture quality in operations such as standards conversion, and also open the door to new processes such as film motion improvement and high quality slow motion portrayal. The equipment described here will enable many of these processes to be studied in real time on a television signal, and will show which aspects of the algorithms require further refinement. The experience gained from this work will be invaluable when designing equipment for broadcast use. >
