Cinematographer, designer, teacher, consultant, and author who came up with the six priorities of electronic cinematography: Harry Mathias’ Priorities for Electronic Cimenatography (in order of importance) 1. Practicality, Flexibility, and Ruggedness 2. Aspect Ratio 3. Sensitivity 4. Gamma or Transfer Characteristic 5. Resolution 6. Standards Acceptance (or Standards Conversion)
Industry:Software
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 stabilize 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
A form of compression in which the codec compresses the data within one frame relative only to itself. Key frames are compressed with intraframe compression because they must reconstruct an entire image without reference to other frames. See Delta Frame, Key Frame. Compare Interframe Compression.
Industry:Software
a) Device that converts the RGB components from the camera into color difference signals and the reverse. b) A set of crosspoints in a particular functional area of a switcher corresponding to a bus (the controls for that matrix). See Audio Matrix and Primary Matrix.
Industry:Software
The evaluation obtained as a result of subjective judgment 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 synchronize to different video signal sync frequencies, allowing its use with various computer video outputs. See Analog Monitor.
