Moving‐image simulation for high‐quality LCD TVs

— A simulation system incorporating pixel response and eye-trace integration was developed to evaluate the moving-image performance of high-quality LCD TVs. A simple formula was derived for moving-edge simulation, which can be used to evaluate the visual effects of arbitrary response waveforms. A model of exponential decay with dynamic time constants is proposed for the LC response to perform moving-image simulation. The model was used to evaluate the visual effects of various motion-blur-reduction techniques. Six different motion-blur-reduction techniques were evaluated in terms of their visual effects. Among them, three basic techniques show certain defects, which are further analyzed by simulation. The other three advanced techniques show excellent performance, and, therefore, are recommended for use in high-quality LCD TVs.
