摘要： Methods, display system and computer readable medium for dynamically adjusting image characteristics in real-time for a user therein. In real-time, a determination is made of a dynamic user position facing one or more fixed display screens. In real-time, and taking into account the dynamic user position, luminance of a plurality of zones is adjusted in a stream of images computed for display on the one or more fixed display screens. The calibrated (or adjusted) stream of images is then displayed onto the one or more fixed display screens. A relative view angle between the dynamic user position and the one or more fixed display screens may be determined, taking into account in real-time the dynamic user position, while adjusting luminance. Adjusting in real-time while taking into account the dynamic user position, may also be performed on color properties of the plurality of zones in the stream of images.

摘要： Systems, apparatuses, and methods for implementing an effective electro-optical transfer function for limited luminance range displays are disclosed. A processor detects a request to generate pixel data for display. The processor receives an indication of an effective luminance range of a target display. The processor encodes pixel data of an image or video frame into a format which matches the effective luminance range of the target display. In one implementation, the processor receives encoded pixel data in a first format, the first format having unused output pixel values which map to luminance values outside of the effective luminance range of the target display. The processor converts the encoded pixel data from the first format into encoded pixel data of a second format which matches the effective luminance range of the target display. A decoder then decodes the encoded pixel data and drives the decoded pixel data to the target display.
