WebAug 27, 2024 · A: In simple terms, CTR indicates the efficiency of the optocoupler. If CTR is low, the input side will need more current drive to the LED in order to create sufficient current at the phototransistor for the output load. Higher CTR also provides some input/output margin as the LED ages. The opto-electronic transfer function (OETF) is the transfer function having the scene light as input and converting into the picture or video signal as output. This is typically done within a camera. The electro-optical transfer function (EOTF) is the transfer function having the picture or video signal as input and … See more This article is about the transfer functions used in pictures and videos and describing the relationship between electrical signal, scene light and displayed light. See more Linear • Raw formats • Some OETF and EOTF have an initial linear portion followed by a non-linear part (e.g. sRGB and Rec.709 ). See more
