A display setting related to the brightness of the middle tones of an image. You can adjust the gamma of an image to lighten or darken the midtones (the middle-gray levels), without significantly changing the dark and light areas (the shadows and highlights).
A term that describes the tonal reproduction characteristics of a video signal.
the curve that describes how the middle tones of your images appear. Often incorrectly referred to as "brightness" and/or "contrast," gamma is a non-linear function. Changing the value of the gamma affects middle tones while leaving the white and black of the image alone. Gamma adjustment is used to compensate for differences between Macintosh and Windows monitors.
Curve that describes how the middle tones of images appear. Gamma is a nonlinear function often confused with "brightness" and/or "contrast." Changing the value of the gamma affects middle tones while leaving the white and black of the image unaltered. Gamma adjustment is often used to compensate for differences between Macintosh and Windows video cards and display.
A measurement of how fast delta changes, given a unit change in the underlying futures price.
The third letter (G, g = Eng. G) of the Greek alphabet.
Gamma expresses how fast Delta changes with a one-point increase in the price of the underlying. Gamma is positive for all options. If an option has a Delta of 45 and a Gamma of 10, then the option's expected Delta will be 55 if the underlying goes up one point. If we consider Delta to be the velocity of an option, then Gamma is the acceleration.
The rate of change of an option's delta for a small change in the price of the option's underlying. See delta.
A unit of measurement of magnetic intensity.
A measure of magnetic field strength; the Earth's magnetic field is about 50,000 gamma. The Moon's magnetic field is only a few gamma.
a unit of magnetic field strength equal to one-hundred-thousandth of an oersted
a computer package designed to facilitate construction of programs that simulate magnetic resonance phenomena
Gamma is a dynamically-typed, object-oriented, interpreted programming language that has been designed and optimized to reduce the time required for building applications. It supports the QNX/Photon and Linux/GTK GUI environments, and has a built-in library of over 300 functions.
emission 3/4 Electromagnetic radiation emitted by atomic nuclei, the wavelength is generally in the range 1 × 10-10 to 2 × 10-13 m.
A high energy photon. This may be emitted by the nucleus of an atom during radioactive decay. Gamma radiation is used in radiation treatment of cancer and for diagnostic purposes in nuclear medicine.
ray a high-energy photon produced in radioactive decay.
