Research on LCD Motion Blur Reduction Based on Volterra Model

The “LCD (Liquid Crystal Display) Motion Blur” problem results from the inherent sample-and-hold nature of LCD and the motion tracking features of the HVS (Human Visual System) can be described in Frequency Domain with the sinc function. This paper presents the fundamentals of LCD motion deblurring using the sinc-1 model which based on the pre-compensation system at first. In order to implement the deblurring theory in the Hardware Environment, the Volterra model instead of the sinc-1 one is considered to establish the pre-compensation system, because of the parameters and order of the former can be determined under certain conditions. Finally, the simulation indicates that the fitting Volterra system is better than the original sinc-1 system. When it is used to deal with the low speed motion images, both effects of the motion deblurring are similar. But in the high speed situation, the effect of the Volterra system is better than the sinc-1 system’s.
