PURPOSE:To flexibly construct a system by freely selecting a frame memory to be composed in the composite image displaying device. CONSTITUTION:This composite image displaying device is provided with (a) a subframe memory management part 106 having a subframe memory part 101 storing image information and a connection identifier 105, (b) a frame memory part 100 which stores image information, an image composition part 102 which outputs the image signal outputted by the subframe memory part 101 and the image signal outputted from the frame memory part 100 together according to a composition instruction signal when receiving the composition instruction signal and then outputs the composite signal, and a frame memory management part 104 which has a connection identifier 103, and (c) an image drawing part 107 which compares the connection identifier 103 and connection identifier 105 with each other and stores the image information by drawing images in the frame memory part 100 that the frame memory management part 104 has and the subframe memory part 101 that the subframe memory management part 106 has when the identifiers are matched with each other, sends the composition indication signal to the image composition part 102 that the frame memory management part 104 has, and puts the image information stored in the frame memory management part 104 and the image information stored in the subframe memory management part 106 together and outputs the composite information. |
