1. SATURATION (COLOR)
The vividness of a color. It is directly related to the amplitude of the chrominance signal
2. SCANNING
The rapid movement of the election beam in a pickup device of a camera or in the CRT of a television receiver. It is formatted in a line-for-line manner
across the photo sensitive surface which produces or reproduces the video picture. When referred to a video surveillance field, it is the panning or the
horizontal camera motion.
3. SELECTIVITY
The extent to which a desired frequency can be differentiated from other frequencies.
4. SENSITIVITY (PICKUP DEVICE)
The amount of current developed per unit of incident Iight. It can be measured in watts with the projection of an unfiltered incandescent source of light at
2870 K degrees to the pickup device surface area. It can be then expressed in footcandles.
5. SHADING
An area of the reproduced scene brightness that is different from the original scene brightness.
6. SIGNAL TO NOISE RATIO
The ratio between a useful video signal and unwanted noise.
7. SINCRONISMO
São pulsos elétricos que são inseridos no sinal de vídeo ou dados para transmissão, com a finalidade de ajuntar as informações na posição correta no local de destino.
8. SPOT FILTER
A small insert used in a lens to increase the f-stop range of the lens
9. STREAKING
A condition in which the objects appear to be extended horizontally beyond their normal outline.
10. SYNC COMPRESSION
The reduction in the amplitude of the sync signal with respect to the picture signal.
11. SYNC LEVEL
The level of the peaks of the synchronizing signal.
