Abstract
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.
Claims3
A method of producing a representation of a digital image by applying a plurality of functions of luma to the digital image, wherein the functions of luma comprise at least a first function and a second function, each function having a value for each luma value in a range of luma values, and each function having an associated display value, the digital image include a plurality of pixels, the method comprising:
- for each pixel, determining which of the first and second function has a maximum value for a luma value of the pixel;
- representing the pixel using the display value associated with the determined function;
- and
- redefining a function of luma selected by a user by applying a user-defined value to the selected function of luma.
