A display control unit displays, in a case where the display control unit is in a startup state or in an abnormal operation state of a general purpose application, a display window of a dedicated middleware even when a startup of the dedicated middleware is completed and a startup of a general purpose middleware is not completed. With this configuration, the user operation is allowed to perform operation to the general purpose application and is not required to wait until the startup of the general purpose middleware is completed. When the startup of the general purpose middleware is completed, a display window of the general purpose application which includes display window data transferred from the general purpose middleware is displayed. Thus, information related to the general purpose application can be promptly provided to a user.
