Gamma, английский
- Гамма
- Коэффициент “гамма”. показатель скорости изменения дельты в результате незначительных колебаний цены базовых акций. гамма принимает максимальное значение, когда цена лежащих в основе опциона акций приближается к цене страйк, и стремится к нулю, своему мин
- A numerical value, or the degree of contrast in a television picture, which is the exponent of that power law which is used to approximate the curve of output magnitude versus input magnitude over the region of interest.
- A correction of the linear response of a camera in order to compensate for the monitor
- Correction law introduced in the camera output signal to compensate for the non-linearity of the crt (cathode ray tube) in video monitors. a typical gamma value is 0.45, which results in the brightness component of the crt picture appearing to be linear.
- 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.
- A correction of the linear response of a camera in order to compensate for the monitor phosphor screen nonlinear response. it is measured with the exponential value of the curve describing the non-linearity. a typical monochrome monitor’s gamma is 2.2, and a camera needs to be set to the inverse value of 2.2 (which is 0.45) for the overall system to respond linearly (i.e., unity).
- The brightness curve of the color spectrum as displayed (or reproduced) on a computer monitor, a printer or scanner.
- Measure of the amount of contrast in an image according to the properties of a gradation curve. high contrast = high gamma and low = low.
- The third letter of the greek alphabet
- The ratio of a change in the option delta to a small change in the price of the asset on which the option is written.
