Gamma
The relationship between the brightness of a spot on the picture tube where the electron beam hit and the level of the video signal. It can be graphed as a curved line. If twice as many electrons are fired at the screen, that spot does not look twice as bright to the human eye, Therefore for video the gamma graph is not straight, or linear. In practicer it also varies with the make and model of the TV set or monitor, the nature and quality of the electronics inside, and also the settings of the brightness and contrast controls. Gamma also applies to film where the intensity of light hitting the film results in the appropriate intensity of the color in the finished print or slide. Adjusting gamma is difficult especially considering that most people cannot tell what is correct unless they have a side by side comparison with the live subject, a supposedly correct photograph of the subject, or a TV that is adjusted correctly. Also personal preferences, comparable to preferences in adjusting stereo bass and treble controls, affects the settings. Typical test patterns for adjusting the gamma consist of series of stripes graduated from black to white, some of them using gray scales, others using halftoning or dithering of pure black and pure white dots. The user is told to adjust controls on the monitor until some stripes are distinguishable and others blend into each other. The instructions for using each gamma chart vary.

Gamma
A measure of the amount of contrast found in an image according to the properties of a gradation curve. High contrast has high gamma and low contrast low gamma.

Gamma
The light output of a CRT is not linear with respect to the voltage input. This non-linearity follows an exponential function that is known as gamma. The camera has the inverse gamma of the CRT so that the resulting stage light input to CRT light output transfer will be somewhat linear, given the restrictions of the video system.

Gamma
Gamma Third letter in the Greek alphabet. Its capital form often stands for Gaia, the goddess or divinity of earth, which in its cosmic aspect is the third stage of evolution. Alphabetically it corresponds to gimel, the third letter in the Hebrew alphabet; and in the English alphabet is replaced by the hard guttural, C.

Gamma
Since picture monitors have a non-linear relationship between the input voltage and brightness, the signal must be correspondingly predistorted. Gamma correction is always done at the source in television systems.

Gamma
Simply, the units in which magnetic survey maps are often contoured. 1 gamma = 1 nanotesla . A unit for stating the magnitude of the magnetic field vector B represented by the number of lines of induction passing through a unit area perpendicular to the vector direction.
1 gamma = 10-5 gauss
= 10-5 lines/cm2
= 10-1 line/m2
= 10-9 weber/m2
= 10-9 tesla = 1 nanotesla

Gamma
Gamma (uppercase Γ, lowercase γ) is the third letter of the Greek alphabet. In the system of Greek numerals it has a value of 3. It was derived from the Phoenician letter Gimel . Letters that arose from Gamma include the Roman C and G and the Cyrillic letters Ge Г and Ghe Ґ.
In Modern Greek, it represents either a voiced velar fricative or a voiced palatal fricative . In Ancient Greek, it represented a voiced velar stop . Before velars, it represents a velar nasal in Modern as well as Ancient Greek, and a double gamma represents a prenasalized voiced velar stop .
