基于ACES的HDR后期制作方案的研究与实现

Research and Implementation of HDR Post-production Solution Based on ACES

HDR(High Dynamic Range,高动态范围)影像技术是近几年来影视行业的新兴技术。它的目的是拓展显示影像的动态范围,使其能够展现视觉上更加贴近真实场景的高动态范围影像。目前,国内外的HDR影视内容制作工业处于起步阶段,并没有形成完善的制作工艺和流程。本文分析了现阶段Dolby Vision、HDR10、HLG这三种关键HDR格式,并将其与ACES结合,研究并实现了基于ACES的HDR影像后期制作解决方案。

The High Dynamic Range(HDR)image technology is a new technology in the film and television industry in recent years.It's aimed at expanding the dynamic range of the display image,so that it can display high dynamic range images that are visually closer to the real scene.Currently,the HDR video production industry at domestic and overseas is in its infancy and has not formed a complete production process.This paper analyses three key HDR formats:Dolby Vision,HDR10 and HLG,and combines them with ACES to study and implement a post-production solution of HDR images based on ACES.
