The luminance range of original scenes varies from outdoor scenes in sunlight with a range possibly exceeding 10000:1, to indoor scenes with controlled lighting, where the range may be reduced to 10:1 or even less. Adjustment of or accommodation to the luminance range, scene is one of the conditions to be evaluated in determining how the scene is to be recorded. It is a test of artistic judgment to place the relative luminances for the objects of interest on a suitable portion of the opto-electronic or opto-photographic transfer function in order to produce the desired subjective quality.
Industry:Software
System of time code that retains all frame numbers in chronological order, resulting in a slight deviation from real clock time.
Industry:Software
An adjustment for keys that determines the sharpness of the key edges. As key gain is reduced, keys become softer at the edges and may be adjusted to be more transparent.
Industry:Software
Low level, short duration dropouts. They correspond to RF envelope dropouts of 10 dB or greater with a duration of 0.5 to 0.8 microseconds.

The Institute of Electrical and Electronics Engineers (IEEE) is the world’s largest technical professional society. Founded in 1884 by a handful of practitioners of the new electrical engineering discipline, today’s Institute includes 46,000 students within a total membership of nearly 320,000 members who conduct and participate in its activities in 150 countries. The men and women of the IEEE are the technical and scientific professionals making the revolutionary engineering advances which are reshaping our world today. And today’s students are the future of the profession. The technical objectives of the IEEE focus on advancing the theory and practice of electrical, electronics, and computer engineering and computer science. To realize these objectives, the IEEE sponsors nearly 800 Student Branches worldwide, as well as scholarships and awareness programs, technical conferences, symposia, and local meetings; publishes nearly 25% of the world’s technical papers in electrical, electronics, and computer engineering; and provides educational programs to keep its members’ knowledge and expertise state of- the-art. The main IEEE information system is in Piscataway, New Jersey, USA.
Industry:Software
The black and white signal (the brightness signal) in color TV. The luminance signal is formed by combining a proportion of 30% red, 50% green, and 11% blue from the color signal. This combined output becomes the luminance (brightness/monochrome) signal.
