RENDERING AND DISPLAYING HDR CONTENT ACCORDING TO A PERCEPTUAL MODEL

摘要

Methods and apparatus for rendering and displaying high dynamic range (HDR) digital image content according to a perceptual model. A model of viewer perceptual range may be determined according to the perceptual model based on inputs including ambient lighting conditions, display panel characteristics (e.g., light leakage and reflected ambient light), and/or display panel settings. The system may determine, according to the model of viewer perceptual range, a brightness level that defines a lower portion and an upper portion of a display space of the display panel, and a maximum rendering value M. Digital image content may be rendered according to the maximum rendering value M to generate HDR content in a dynamic range of (0.0-M). The rendered HDR content may then be mapped into the display space of the display panel according to the brightness level.

1. A system, comprising:
a display panel; and one or more processors configured to implement:
a dynamic display module configured to:
determine a model of viewer perceptual range under current ambient conditions of the display panel according to a perceptual model, wherein the perceptual model determines the model of viewer perceptual range according to inputs including one or more of ambient lighting conditions, display panel characteristics, or display panel settings;determine, according to the model of viewer perceptual range, a brightness level B that defines a lower portion and an upper portion of a display space of the display panel, and a maximum rendering value M;a rendering pipeline configured to render digital image content according to the maximum rendering value M to generate high dynamic range (HDR) content in a dynamic range of (0.0-M); anda display pipeline configured to map the rendered HDR content into the display space of the display panel according to the brightness level B.
