Nonlinearity compensated smooth frame insertion for motion-blur reduction in LCD

A nonlinearity compensated smooth frame insertion (NCSFI) method is proposed to reduce motion-blur caused by hold-type display in LCD. Firstly, each original frame is duplicated into two frames. Then in the first frame, spatial high frequency is removed and in the second frame, the same amount of high frequency is enhanced. Finally, look-up table based nonlinearity compensation is applied to the two new frames to compensate the nonlinearity between gray level and panel luminance. Experiments on real-time display system show that the proposed NCSFI method can reduce motion-blur significantly without luminance distortion
