A system converter device converts video signals based on the MUSE system to video signals based on the NTSC system. First, the number of scanning lines of each odd number field and each even number field of a MUSE signal is converted to 525 lines by a signal processing circuit. Registration processing portion positions the scanning line signals of continuous even and odd number fields to coincide with each other. The degradation of video signals caused by conversion is prevented because the number of scanning lines are directly converted to the desired number of lines. The circuit configuration of this system converter device is also simplified.
