The need to sample at least twice the highest desired frequency in the signal
Light flare that occurs when the iris on a lens is opened wide
Cutting off extreme white or black parts of the signal that extend beyond desired limits will occur to ensure that the signal level stays in specs
Compensating for the fact that camera imagers tend to emphasize brighter luminance values, and under amplify low lights
Process where video above normal levels is surpressed some
Correction values are often added to the R, G, B video values to correct for imperfections in the prism’s ability to separate the primary colors
The increase or decrease in the amplitude of a signal
In the case of video it sets a value for black video levels
Converting RGB video paths and into Y, B-Y, and R-Y paths
