  • Publication number: 20080234843
    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.

  • Patent number: 7397476
    Abstract: In response to a requirement of transferring a file from a personal computer PC to a projector 10 that is output by dragging and dropping a corresponding file icon onto a projector icon, a CPU 50 requires setting of a password. The CPU 50 maps the preset password to a file and transfers the file with the password to an external storage device of the projector 10. The projector 10 requires input of a password, which is expected to be assigned to the file, and allows reproduction of the file when the input password is coincident with the preset password.

  • Patent number: 7266772
    Abstract: Commands and data transferred via a network line NL are input to an ASP terminal portion 20 via a network interface controller 220. A first CPU loads a client application corresponding to the command and generated user interface image data via a graphics controller 210. A video signal conversion circuit 310 receives image data from the graphics controller 210 and transfers the processed image data to an LCD drive circuit 330. LCD drive circuit 330 drives an LCD 332 in response to the received image data to project the desired image data onto a projection screen.

  • Patent number: 7246317
    Abstract: A scenario creating device creates a scenario file to be supplied to a scenario reproducing device capable of reproducing only image files of a first predetermined format in accordance with a scenario file for pagewise sequential display of images. The scenario creating device includes an input section having a pointing device, a display section, and a scenario creating section. The scenario creating section provides a display of an execution icon on the display section for causing the scenario creating section to execute a scenario creating process. When a single file icon for a single source file of a second predetermined format is dragged and dropped on the execution icon by way of operation of the pointing device, the scenario creating section creates the scenario file on the basis of the scenario information and generates the image files of the first predetermined format on the basis of the image information.

  • Patent number: 7229177
    Abstract: Embodiments of the invention restrain temperature rise in a light exiting-side polarizer included in a liquid crystal light valve without limiting the quantity of light incident on the liquid crystal light valve and a projector that has a liquid crystal light valve to modulate incident light in accordance with a provided image signal and that projects an image represented by modulated light exiting from the liquid crystal light valve. The projector has a black level adjusting unit to adjust black level of the image signal, a temperature-detecting unit to detect temperature of the light exiting-side polarizer, and a control unit to control operation of the black level-adjusting unit. The control unit is characterized by causing the black level-adjusting unit to adjust the black level of the image signal on the basis of the temperature detected by the temperature-detecting unit in order to restrain temperature rise in the light exiting-side polarizer.

  • Patent number: 7209135
    Abstract: The invention provides an image display apparatus that efficiently adjusts a video display even when a change takes place in an input signal. The image display apparatus includes a video input device that receives a video signal, a video display that displays an optical image based on an input signal S1 from the video input device, and a video signal adjusting device that adjusts the display setting of the video display based on a signal mode of the input signal S1. The image display apparatus further includes a determining device that causes the video display adjusting device to adjust the display setting of the video display. The determining device includes an apparatus startup detector unit that detects whether a startup of the image display apparatus creates a change in the input signal, and a signal change detector unit that detects the change in the input signal. The determining device determines whether to cause the video display adjusting device to adjust the display setting only when it is needed.

  • Patent number: 7142245
    Abstract: A projector is provided to suppress the degradation of the image quality of movies that are displayed on an image display device. The projector is configured to have a DVD playback function. Accordingly, when movie data that was read out from a DVD includes a movie film having a frame rate of 24 fps, a frame rate conversion unit converts the frame rate from 24 fps to 72 fps without performing a 2 to 3 pull down telecine conversion. In addition, the driving frequency of a liquid crystal panel is also switched to 72 Hz according to the conversion of frame rate.
