Multi-Image Application Format adds support of HDR
Within less than two years after it has reached its last milestone of standard developments the Multi-Image Application Format (MIAF; ISO/IEC 23000-22) has become the default format for the storage of still pictures within the smartphones. However, it lacks support of one of the killer features for image quality enhancement, i.e., High Dynamic Range (HDR). To quickly answer such market needs, WG11 (MPEG) has promoted the 2nd Amendment to the Multi-Image Application Format, MIAF HEVC Advanced HDR profile, and other clarifications, its first milestone of ISO standard development process. This amendment adds support of the use of PQ (Perceptual Quantizer) and HLG (Hybrid Log Gamma) color transfer characteristics and P3 mastering display color volume properties with D65 white point for HEVC encoded still pictures to support widely used HDR technologies. It is currently expected that the standard will reach its final milestone by mid-2021.
