US 2026/0141876 A1 · Dynamic System Optical-to-Optical Transfer Functions (OOTF) for Providing a Perceptual Reference

Abstract

Disclosed are dynamic system optical-to-optical transfer functions (OOTF), which adapt displayed content to provide a so-called “perceptual reference” effect for the viewer, wherein, as the current viewing conditions depart from a “reference” viewing scenario, the dynamic system OOTF adapts the content and/or display to provide the viewer with as close as possible to the perceptual effect of the “reference” viewing scenario. The dynamic system OOTF may perform one or more of the following adaptation processes: adapting media content from a source color space to a linear XYZ color space; adapting media content from a linear XYZ color space to a display device's color space; automatically adjusting display device brightness, white point, and/or black point; adapting media content from an intended viewing environment to a common compositing space's fixed viewing environment; and/or adapting media content from the common compositing space's fixed viewing environment to that of the viewer's current viewing conditions.

Dependent claims

A method of displaying content on a display device, comprising:

receiving data indicative of a first content item;
linearizing the data indicative of the first content item according to an inverse transfer function associated with the first content item;
mapping the linearized data indicative of the first content item from a first color space gamut associated with the first content item to a second color space gamut associated with a common compositing space;
modifying the mapped, linearized data indicative of the first content item based on at least one of:
(a) a first difference between a first intended viewing condition associated with the first content item and a second intended viewing condition associated with the common compositing space;
and
(b) a second difference between a first intended viewer adaptation level associated with the first content item and a first predicted viewer adaptation level;
and
encoding the modified data indicative of the first content item according to a transfer function associated with the common compositing space.

6 more elements

A non-transitory program storage device comprising instructions stored thereon to cause one or more processors to:

receive data indicative of a first content item;
linearize the data indicative of the first content item according to an inverse transfer function associated with the first content item;
map the linearized data indicative of the first content item from a first color space gamut associated with the first content item to a second color space gamut associated with a common compositing space;
modify the mapped, linearized data indicative of the first content item based on at least one of:
(a) a first difference between a first intended viewing condition associated with the first content item and a second intended viewing condition associated with the common compositing space;
and
(b) a second difference between a first intended viewer adaptation level associated with the first content item and a first predicted viewer adaptation level;
and
encode the modified data indicative of the first content item according to a transfer function associated with the common compositing space.

6 more elements

A device, comprising:

a memory;
a display device;
and
one or more processors operatively coupled to the memory, wherein the one or more processors are configured to execute instructions causing the one or more processors to:
receive data indicative of a first content item;
linearize the data indicative of the first content item according to an inverse transfer function associated with the first content item;
map the linearized data indicative of the first content item from a first color space gamut associated with the first content item to a second color space gamut associated with a common compositing space;
modify the mapped, linearized data indicative of the first content item based on at least one of:
(a) a first difference between a first intended viewing condition associated with the first content item and a second intended viewing condition associated with the common compositing space;
and
(b) a second difference between a first intended viewer adaptation level associated with the first content item and a first predicted viewer adaptation level;
and
encode the modified data indicative of the first content item according to a transfer function associated with the common compositing space.
