Abstract: Systems and methods for encoding and decoding multiple-intent images and video using metadata. When encoding an image as a multiple-intent image, at least one appearance adjustment may be made to the image. Metadata characterizing the at least one appearance adjustment may be included in, or transmitted along with, the encoded multiple-intent image. When decoding a multiple-intent image, a system may obtain a selection of a desired rendering intent and, based on that selection, either render the multiple-intent image with the applied appearance adjustments or may use the metadata to invert the appearance adjustments and recover the image pre-appearance adjustments.

Abstract: Novel methods and systems for compensating for ambient light around displays are disclosed. A shift in the PQ curve applied to an image can compensate for sub-optimal ambient light conditions for a display, with the PQ shift being either an addition to a compensation value in PQ space followed by a subtraction of the compensation value in linear space, or an addition to the compensation value in linear space followed by a subtraction of the compensation value in PQ space. Further adjustments to the PQ curve can also be made to provide an improved image quality with respect to image luminance.

Abstract: Methods and systems for chromatic ambient-light support are provided. Given an input surround correlated color temperature (CCT), its normalized value is mapped to a preferred gray CCT value using a sigmoid-like function model generated based on viewer experimental data. The preferred gray CCT value is then mapped to an adjusted CCT value so that viewing conditions on a display with the input surround CCT value match a D65 surround CCT value.
