VIDEO TONE MAPPING FOR CONVERTING HIGH DYNAMIC RANGE (HDR) CONTENT TO STANDARD DYNAMIC RANGE (SDR) CONTENT

摘要

Techniques are described for a method, an apparatus, a system and at least one machine readable medium to generate standard dynamic range videos from high dynamic range videos, the method comprising the steps of: applying an inverse gamma correction; applying a matrix multiplication that converts a color space; stretching a luminance range based at least in part on one or more stretching factors; and applying a forward gamma correction.
