Multi-tone representation of a digital image on a digital nonlinear editing system

摘要

A system and method for generating a multi-tone representation of a digital image by applying a plurality of functions of luma to the digital image. The functions of luma comprise at least a first function and a second function, where each function has a value for each luma value in a range of luma values. Each function also has an associated display value. The digital image includes a plurality of pixels, where for each pixel, it is determined which of the first and second functions has a maximum value for a luma value of the pixel. Each pixel is represented using the display value associated with the determined function.
