Patent ID: 8688811

Claim:
A projection device for connection to a terminal device via a network, comprising: circuitry configured to: confirm whether an IP address of the projection device has been changed; and create an executable file for executing image transfer software by using a changed IP address that is the IP address that has been changed, if the IP address is confirmed to have been changed; a transmitter configured to transmit the executable file in response to a request from the terminal device; a receiver configured to receive, from the terminal device in which the image transfer software has been run by the executable file, a connection based on the changed IP address and receive a transfer of image information that is information of an image being displayed in the terminal device; and a projector configured to project the image being displayed in the terminal device by using the image information, wherein, if the IP address is confirmed to have been changed, the circuitry creates the executable file by creating a configuration file in which the changed IP address is described and appending the configuration file to a main file that refers to the configuration file and executes the image transfer software.
