Abstract

In this paper a model for the LCD moving image representation is presented. It is combined with a human visual system perception model to analyze the influence a display has on the perceived image quality. Two main fields of moving image representation are discussed: The spatial properties of a display, namely the pixel shape or spatial aperture, and the temporal properties of a display given by the display response or temporal aperture. Both properties affect the image quality: The LCD pixel shape leads to a higher sharpness impression but also to an enhancement of errors such as block noise. The temporal LCD hold-type behavior combined with the slow response of the liquid crystal lead to a motion blur in moving objects. Both effects are explained numerically and analytically and demonstrated with simulation results.
