Multi-screen display apparatus and video switching processing apparatus

摘要: When a sub-image (A) and (B) are displayed as semi-moving pictures on multi-screen, the fields of input sub-images determined. By setting field determination result one condition for write to memory 114, can be stably written 114 in either odd (ODD) or even (EVEN), read screen without flickering characters due line flicker. Furthermore, when video signals switched channel switch an switch, operation remote controller 501 issue instruction so that 509 is stopped according generated signal, image still image. In response new number increase lines picture elements set n. The writing performed m times (m natural number) every other field. According n×m, incremented, updated at gradually from end combination vertical horizontal directions.
