An object is to provide a technique capable of reducing an inter-SoC communication volume. The screen generation device includes a first SoC, a second SoC, and an allocation unit. The allocation unit defines a plurality of superposition sequence layers having a superposition sequence and selected from the plurality of first drawing layers and the plurality of second drawing layers, allocates, among the plurality of superposition sequence layers, a consecutive superposition sequence layer cluster being consecutive two or more superposition sequence layers in the superposition sequence, to the first SoC, and allocates remaining superposition sequence layers being one or more superposition sequence layers other than the consecutive superposition sequence layer cluster to the second SoC.
