Gamma (OETF & EOTF)

The optical-transfer function (OTF) is defined as the Fourier transform of the point-spread function and is thus generally a two-dimensional complex function.

For displays, an electrical signal must be converted back to an image. This is another non-linear function called the Electro-Optical Transfer Function (EOTF).

This Recommendation specifies the reference electro-optical transfer function (EOTF) that the displays used in HDTV programme production should follow in order ...

The MTF can be calculated as the magnitude of the Fourier transform of the PSF or as an autocorrelation of the pupil function. G. Boreman, Modulation Transfer ...

This tutorial introduces the theory and applications of MTF, used to specify the image quality achieved by an imaging system. It covers basic linear systems ...

2019年10月15日 — The EOTF is the mathematical function for transferring an electronic signal into the desired optical signal (i.e. digital to analog function).

The electro-optical transfer function (EOTF) is the transfer function having the picture or video signal as input and converting it into the linear light ...

2021年6月21日 — OETF is the non-linear transfer function of the optical light into the electrical signal in the camera. This used to be called the 'Camera Gamma ...
