Based on these findings, the inventor of the present invention has realized that the workload on the projector apparatus in processing the communication tasks during the activation or projection process may be reduced, if {TAIL ~ the communication tasks} that are usually performed during the activation or projection process are later performed during {HEAD ~ the cooling process}
