Abstract
A method of deriving a transmission nonlinearity which equalizes noise visibility over the range of displayed gray levels is described in this article. The technique is based on the measured thresholds of the eye. An improvement estimated at between 1 and 2 dB over the present situation, where gamma precorrection performs a similar function, was found. This approach may lend itself to the determination of quantization levels for more complex coding schemes.
