WebIf you recall the two segments for HDR, the goal of SDR dimming is to blend the separate layers by mapping the SDR transfer function to the SDR segment of the HDR transfer function, not the entire HDR luminance range, which is what currently occurs on Android 12.

WebJan 24, 2024 · About blending: Although the transfer functions for SDR and HDR are very different, I think both to some extent approximate the human brightness perception (but the HDR TF does it much better than the SDR one). Which means there's a good chance that blending in non-linear light might look quite similar with both SDR and HDR. blow up pool with filterWebSep 27, 2024 · HDR monitors strive to produce a close replica of extremely bright scenes by using a common Electro-Optical-Transfer-Function (EOTF) which ensures that images will be closer to what human eye see.
