The Effect of Synthetic Shutter on Judder Perception—an HFR & HDR Data Set and User Study

摘要

While high dynamic range (HDR) enhances the viewing experience by rendering a more life-like image, it amplifies motion artifacts due to the higher temporal contrast sensitivity of the human visual system at higher luminance levels and higher contrast ratios typical for HDR images. These motion artifacts are known as strobing or judder. They can be overcome by increasing temporal resolution, also known as higher frame rate (HFR). This article introduces an HFR and HDR data set for research on judder perception and presents a user study on motion portrayal. The data set is designed to visualize motion in HDR and includes versions of different frame rates. The user study compares the motion portrayal of four different synthetic shutters and two frame rates.
