In MUSE, pictures' resolution depends on the characteristics of filters such as pre-filters and interpolating filters, and moving pictures have lower resolution than still pictures. We are trying to improve moving pictures' resolution. Extension of the fiters' passband and implementaion of a vertical low-pass filter have been simulated with computer in order to investigate the improvement of moving pictures' resolution. As a result, we have found that we can improve moving pictures' resolution with little disturbance caused by aliasing and ringing.
