Method for Eliminating LCD Motion De-blurring Model's Pole
|
Abstract:
The sinc-1 model can reduce the LCD motion blur effectively, however, it can not restore the correct frequency components on the pole and is hard to implement on hardware. This paper presents a novel method which is trying to improve the LCD motion blur phenomenon from the view of system identification. The method uses the Volterra nonlinear system that is based on the VSSLMS (variable step size least mean square) algorithm to fit the sinc-1 model, which is a non-perfect inverse system to the LCD motion blur system for the pole problem. Simulation results demonstrate that the performance of the proposed simple method can avoid the pole problem of sinc-1 model and can be implemented on hardware easily.
