Consideration of the Viewing Mechanism on Hold Type Displays for Motion Pictures

Abstract

The mechanism of viewing which arises picture quality impairment observed when motion pictures are displayed on a hold type display such as a TFT-LCD has been studied. At first, we assume two models of visual system, estimate theoretical outputs of models and investigate which model is more proper as a viewing mechanism by subjective tests. As a result, it became clear that it is more possibility that the effect of temporal summation of the visual system work first for the observed motion picture, and secondly the picture is processed by the visual nonlinearities. It is also clear that a effective MTF for observed pictures has a nearly sin x/x characteristic which vary with moving velocities of pictures.
