In order to appear as bright as a 2D system, a perfect temporally multiplexed stereo display would therefore require twice the photon flux, even if it avoided all other losses. Yet this assumption has not been tested in human observers. Here, we examine how brightness perception depends on when photons are delivered to each eye. We find that stimuli appear equally bright when light is presented in alteration to each eye as when it is presented simultaneously in both eyes. Thus, there is no brightness advantage for temporally multiplexed stereo. We do find a novel non-linearity affecting brightness perception in short impulses of light, as in a Cathode Ray Tube. Light pulses presented at low frequency appear brighter than when the same number of photons is delivered at high frequency. However, this does not apply to the longer-duration light steps found in modern displays such as Liquid Crystal Displays. We conclude that, when evaluating such stereoscopic displays, one should measure luminance with a single photometer pointing at the screen through the same eyewear as the viewer. The recorded luminance then can be directly compared to that measured by a single photometer for 2D displays. Additionally, we point out that due to the logarithmic relation between physical luminance and perceived brightness in the human visual system, halving luminance does not halve the perceived brightness.", "abstract$meta": { "confidence": "high", "note": "Parsed from NLM article XML (_source/SMPTE/HIGHWIRE/Source Bak/smptem/10.5594_M001511.xml)", "source": "parsed", "updated": "2026-05-22T21:44:19.125Z", "version": "smpte-conference-paper-nlm@v1" }, "authors": [ { "affiliation": "Newcastle University, UK, Institute of Neuroscience, Framlington Place, Newcastle-upon-Tyne, NE2 4HH", "name": "Zoltán Derzsi" }, { "affiliation": "Newcastle University, UK, Institute of Neuroscience, Framlington Place, Newcastle-upon-Tyne, NE2 4HH", "name": "Sindre Henriksen" }, { "affiliation": "Newcastle University, UK, Institute of Neuroscience, Framlington Place, Newcastle-upon-Tyne, NE2 4HH", "name": "Jenny Read" } ], "authors$meta": { "confidence": "high", "note": "Object form (schema 2.3.0) migrated from string form via migrateAuthorsToObjectForm.js; bio/affiliation backfilled from _source/SMPTE/HIGHWIRE/ NLM ++", "source": "parsed", "updated": "2026-06-23T00:04:25.562Z", "version": "authors-migrate-object-form@v1" }, "contentType": "orig-research", "contentType$meta": { "confidence": "high", "note": "Canonical-confirmed full paper (summary-abstract set is orig-research in the SMPTE canonical repos); HIGHWIRE-era abstract label was a delivery artifact", "originalValue": "summary-abstract", "source": "resolved", "updated": "2026-07-09T19:12:47.628Z", "version": "contenttype-fixes@v1" }, "copyright": { "holder": "Society of Motion Picture and Television Engineers, Inc.", "holder$meta": { "confidence": "high", "note": "Parsed from NLM article XML (_source/SMPTE/HIGHWIRE/Source Bak/smptem/10.5594_M001511.xml)", "source": "parsed", "updated": "2026-05-22T21:44:19.125Z", "version": "smpte-conference-paper-nlm@v1" }, "year": "2013", "year$meta": { "confidence": "high", "note": "Parsed from NLM article XML (_source/SMPTE/HIGHWIRE/Source Bak/smptem/10.5594_M001511.xml)", "source": "parsed", "updated": "2026-05-22T21:44:19.125Z", "version": "smpte-conference-paper-nlm@v1" } }, "copyright$meta": { "confidence": "high", "note": "Parsed from NLM article XML (_source/SMPTE/HIGHWIRE/Source Bak/smptem/10.5594_M001511.xml)", "source": "parsed", "updated": "2026-05-22T21:44:19.125Z", "version": "smpte-conference-paper-nlm@v1" }, "docId": "10.5594-M001511", "docId$meta": { "confidence": "high", "note": "Derived from DOI 10.5594/M001511", "source": "parsed", "updated": "2026-05-22T21:44:19.125Z", "version": "smpte-conference-paper-nlm@v1" }, "docLabel": "SMPTE Meetings and Conferences ( October 2013)", "docLabel$meta": { "confidence": "medium", "note": "Composed from venue title, volume/issue and date", "source": "inferred", "updated": "2026-05-22T21:44:19.125Z", "version": "smpte-conference-paper-nlm@v1" }, "docTitle": "Your Eyes Don't do the Math: Effect of Temporal Display Protocols on Perceived Brightness", "docTitle$meta": { "confidence": "high", "note": "Parsed from NLM article XML (_source/SMPTE/HIGHWIRE/Source Bak/smptem/10.5594_M001511.xml)", "source": "parsed", "updated": "2026-05-22T21:44:19.125Z", "version": "smpte-conference-paper-nlm@v1" }, "docType": "Conference Paper", "docType$meta": { "confidence": "high", "note": "NLM
