  • Patent number: 9405768
    Abstract: A technique for enabling scenario files and image files for supply to a scenario generating device to be created easily is provided. The scenario creating device creates a scenario file supplied to a scenario reproducing device capable of reproducing only image files of a predetermined format. The scenario creating device comprises: an input section including a pointing device; a display section; and a scenario creating section for creating the scenario file. The scenario creating section provides a display of an execution icon on the display screen for causing the scenario creating section to execute a process. When a file icon for a source file of a predetermined format including pagewise scenario information and image information is dragged and dropped on the execution icon by means of operation of the pointing device, a scenario file is created on the basis of the scenario information, and an image file of the predetermined format is generated on the basis of the image information.

  • Patent number: 8155768
    Abstract: A projector that projects images includes a projection display module by which the projector projects the images, a network interface by which the projector can communicate with a network, and a web server module coupled to the network interface and to the projection display module. The web server module, in response to a request to provide a working status of the projection display module received through the network interface from a client over the network, sends working status information representing the working status through the network interface to the client over the network. The web server module also, in response to control information received through the network interface from the client over the network in response to the sent working status information, controls the working status by sending a control signal to the projection display module based on the control information.
