Core Concepts VOD: The Evolution of Motion Imaging
Session Type 2020
The first video image, transmitted in the 19th century, had no frame rate and very limited spatial resolution and dynamic range. Real television, born in the 20th century, involved trade-offs involving those three characteristics and more, such as sound, color, and stereoscopic depth. Some early solutions, such as line interlace to reduce frame rate while maintaining critical flicker-fusion frequency, have changed to problems needing new solutions.
