The evaluation obtained as a result of objective measurement of the quantitative image parameters (including tone scale, contrast, linearity, colorimetry, resolution, flicker, aliasing, motion artifacts, etc.)
Industry:Software
The time range measured in micro- or nanoseconds over which a video decoder can “lock” or stabilise a signal. Digital out of range signals may require “rubber-band” buffering using a parallel shift register (FIFO) to reduce the locking range.
Industry:Software
This signal is a variation of the sine-squared pulses.
Multipulse allows for the simultaneous evaluation of group-delay errors and amplitude errors at the various frequencies. Distortions show up in multipulse as distortions of the baseline as was seen in the Chrominance to Luminance Gain and Delay measurements or the Group Delay measurement.
Refer to the figure and to the Sine-Squared pulse discussion.
Industry:Software
The term used to describe a subject’s main source of illumination.
When shooting outdoors, the key light is usually the sun.
Industry:Software
A microphone is a transducer which converts sound waves to electrical impulses. Microphones typically generate very low signal levels requiring low noise, high fidelity, pre-amplification to boost the output signal to a level compatible with audio amplifier circuitry.
Good microphone preamplifiers provide precise matching of microphone impedance and low-noise electronic components.
Industry:Software
The evaluation obtained as a result of subjective judgement of a displayed image by a human observer.
Industry:Software
The time before a machine is activated and the time it is ready for use.
Industry:Software
A monitor (also referred to as multi-sync or multifrequency) which can synchronise to different video signal sync frequencies, allowing its use with various computer video outputs. See analogue Monitor.
Industry:Software
A key mode which allows use of independent key mask generators to create a pattern to prevent some undesirable portions of the key source from cutting a hole in the background. This is also possible using externally generated masks on the Vista.
Industry:Software
In video transmission, refers to the mechanical vibration of the elements of an electron tube resulting in a spurious modulation of the normal signal. This usually results in erratically spaced horizontal bars in the picture.
