Abstract

PURPOSE:To suppress the increment of a picture storing part connecting part without being influenced by the number of combined storage parts by allocating discriminators for respectively discriminating picture storing parts included in a picture information output part to the picture storing parts, recognizing each discriminator by a single picture storing part connecting part to connect the picture storing part corresponding to the discriminator. CONSTITUTION:A connection part selecting part 108 reads out a picture information output part discriminator 103 from a picture information managing part 112 and reads out a picture storing part connecting part discriminator 109 from a connection part managing part 107 to select a picture storing part connecting part 106 having the same identifier as the identifier 109. The selecting part 108 issues a connection signal to the connecting part 106, which reads out a picture storing part identifier 110 from a picture information output part 102 having the same identifier as the identifier 109. The connecting part 106 reads out a plotting signal generating part identifier 111 from a plotting signal managing part 105 and selects a plotting signal generating part 104 having both the identifiers 110, 111.
