50‐3: Electro‐Optical Transfer Characteristic, the Undervalued Display Feature

This paper reviews specifications for (moving) image production and exchange (e.g. Rec.709, sRGB) and explains the importance of the involved nonlinear transfer functions, EOTFs, for the visual experience of the observer. The role of the inverse of the electro‐optical transfer function of the (legacy) CRT for transformation of camera signals into approximate perceptionally uniform scales is highlighted and the necessity of a non‐linear overall transfer characteristics is substantiated.
