The '''opto-electronic transfer function''' ('''OETF''') is the [[Transfer function|tranfertransfer function]] having the scene light as input and converting into the picture or video signal as output. This is typically done within a [[camera]].<ref name=":0">{{Cite web|title=BT.2100 : Image parameter values for high dynamic range television for use in production and international programme exchange|url=https://www.itu.int/rec/R-REC-BT.2100-2-201807-I/en|access-date=2021-02-02|website=www.itu.int}}</ref>

The '''electro-optical transfer function''' ('''EOTF''') is the [[Transfer function|tranfertransfer function]] having the picture or video signal as input and converting it into the linear light output of the display.<ref name=":0" /> This is done within the display device.

The '''opto-optical transfer function''' ('''OOTF''') is the [[transfer function]] having the scene light as input and the displayed light as output. The OOTF is the result of the OETF and the EOTF and is usually non-[[Linear function (calculus)|linear]].<ref name=":0" />
