Abstract
In this paper we study the effects of the dynamic modulation transfer function (MTF) on image quality and on the performance of electrooptical displays. The dynamic MTF of phosphor based electrooptical displays can be expressed by1 where r is the time constant defined as the duration in which the phosphorescence decays to 1/e of its maximum value and f is the spatial frequency parameter. The model can be used to correctly estimate2 the effects of the dynamic MTF on display images. In this paper the inverse filters, designed using the concept of the dynamic MTF, are used to restore motion-smeared images. Several new and important statistical parameters have been identified for estimating the degree of image degradation. These parameters were used to quantify the degree of restoration achieved using inverse filters. Also, based on these definitions, the optimum relationship between the image quality and velocity characteristics of the inverse filters was identified.
