Abstract
One or more levels of maladaptation are calculated relative to frames of media content having abrupt jumps from periods of low illumination to bright illumination when visual acuity may be lost and/or discomfort may be experienced. These levels of maladaptation may be correlated with subjectively determined levels of perceived luminance discomfort. Based upon the levels of perceived luminance discomfort that can be derived from the levels of maladaptation, the media content may be adjusted.
Claims20
A computer-implemented method, comprising:
- analyzing media content and computing one or more adaptation states relative to the media content by estimating a perceived magnitude of maladaptation;
- quantifying the perceived magnitude of maladaptation in terms of perceived luminance discomfort by correlating the one or more adaptation states to one or more corresponding levels of perceived luminance discomfort experienced by one or more viewers of test media content, the test media content comprising known variations in luminance;
- and
- adjusting luminance of the media content to comport with one or more desired luminance-based effects relative to the perceived luminance discomfort.
1 more element
A system, comprising:
- one or more processors;
- and
- a memory having computer code being executed to cause the one or more processors to:
- analyze one or more pixels of a frame of media content;
- compute one or more adaptation states by estimating a perceived magnitude of maladaptation relative to each of the one or more pixels;
- quantify the perceived magnitude of maladaptation in terms of perceived luminance discomfort by translating the one or more adaptation states to one or more estimates of perceived luminance discomfort experienced by one or more viewers of test media content, the test media content comprising known variations in luminance, when the one or more adaptation states is indicative of maladaptation of a visual system viewing the media content;
- and
- adjust luminance of the media content to comport with one or more desired luminance-based effects relative to the perceived luminance discomfort.
