Patent ID: 8566905

Claim:
An electronic device comprising: a display part; a system control part that designates, by execution of a processor of the electronic device, a display target to be displayed by the display part and switch the display target to another display target; a display control part that instructs, by execution of the processor, the display part to display an operation screen corresponding to the display target designated by the system control part; and a receiving part that receives, by execution of the processor, a request, including an application identification data (ID), for initiating an exclusive use of the display part from a use restriction application and receives a request, including the application ID, for terminating the exclusive use of the display part from the use restriction application, the receiving part determining to permit the request for terminating the exclusive use after confirming that the application ID has not changed; wherein, upon detecting operation of another application having another application ID and another operation screen, the system control part sends a display target release request to the receiving part to turn over a position of exclusively using the display part to the other application, wherein in a case where the receiving part received the request for initiating the exclusive use of the display part, the system control part is configured to cease switching the display target to the other display target, requested by the other application, until the receiving part receives the request for terminating the exclusive use of the display part from the use restriction application.
