<P>PROBLEM TO BE SOLVED: To provide an image projection device etc., preventing image interruption during image projection if an IP address is changed during the projection, to improve continuous availability of image projection at a PC terminal. <P>SOLUTION: The image projection device includes: HTTP processing means for processing an HTTP request, including an image data, received from a terminal; and IP address change means for changing an IP address. When changing an IP address, the IP address change means notifies the HTTP processing means of the changed IP address, and changes the IP address to the changed IP address after receiving an IP address change permission notification from the HTTP processing means. On receipt of an HTTP request after the notification reception of the changed IP address, the HTTP processing means generates an HTTP response including a redirect request to the changed IP address. After responding with the HTTP response, the HTTP processing means performs IP address change permission notification to the IP address change means. <P>COPYRIGHT: (C)2013,JPO&INPIT |
