An Overview of End-to-End HDR

High Dynamic Range (HDR) has been a hot topic in decades and recently there are technology breakthroughs in multiple areas including HDR video, HDR photography, and HDR displays. However, if users want to show an HDR image or play an HDR video on a mobile device, a system-level HDR support is required to make it happen. This paper gives a brief introduction to the end-to-end HDR ecosystem covering topics from HDR capture to compression to display, which can benefit not only HDR related module designs in chipset, but also in standard development for more efficient algorithm and metadata proposals.
