Image processing and displaying methods for devices that implement color appearance models

摘要

Embodiments of the invention relate generally to image and display processing, and more particularly, to systems, apparatuses, integrated circuits, computer-readable media, and methods that facilitate the prediction of the appearance of color in images for different viewing environments, including high dynamic range images. In some embodiments a method can modify color associated with a source environment at a target environment. The method can include applying different non-linear functions to transform subsets of data representing a color of a sample at the source environment into transformed subsets of data, and generating data representing a chroma correlate as an appearance correlate independent of data representing a hue-related correlate. The chroma correlate can be configured to generate the color at a device at the target environment.

1. A method of modifying color associated with a source environment for presentation at a target environment, the method comprising:
applying different non-linear functions to transform subsets of data representing a color of a sample at the source environment into transformed subsets of data; and generating data representing a chroma correlate as an appearance correlate independent of data representing a hue-related correlate, wherein the chroma correlate is configured to generate the color at a device at the target environment; and wherein applying the different non-linear functions further comprises: determining each of the transformed subsets of data as a function of a subset of data representing a white point, the subset of data representing the white point being one of a number of subsets of data representing the white point.
