A video processor includes a receiving section that receives video information representing video images and luminance-related information on the luminance of the video images and a video processing section that determines an expansion target luminance range of the video images based on the luminance-related information and expands the expansion target luminance range in such a way that the maximum luminance in the expansion target luminance range increases.

Video processor, display apparatus, and video processing method

An image processing device adapted to perform image processing on image information input, and then output the image information includes a first image processing section adapted to perform image processing on the image information, and include a first storage section to store the image information, and a second image processing section adapted to perform image processing on the image information from the first image processing section, and include a second storage section to store the image information. The first image processing section performs a process of reducing an image size of the image information stored in the first storage section and raising a refresh rate, and the second image processing section performs a process of enlarging an image size of the image information stored in the second storage section.

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.

In one embodiment, a control method for a projector comprises picking up an image of an area including a screen and an image light and generating a picked-up image; calculating each side of an outer peripheral line of the image light, based on the picked-up image; calculating each side of an outer peripheral line of the screen, based on the picked-up image; and calculating a correction image light modulation area that is an area in a part of a light modulation area so as to fit inside a second imaginary screen outer peripheral line.

Projector and control method for projector

First imaginary screen outer peripheral line is calculated supplementing one side that is undetected with one side of an outer peripheral line of image light that is calculated, an imaginary screen aspect ratio that is an aspect ratio of an area defined by the first imaginary screen outer peripheral line is calculated, whether the imaginary screen aspect ratio is more vertically oriented than a first ratio or not is determined. When a result of the determination of the imaginary aspect ratio is more vertically oriented than the first ratio, the imaginary screen aspect ratio is changed to second ratio that is different from the first ratio, and the one undetected side is calculated according to the second ratio, and the first imaginary screen outer peripheral line is corrected and a second imaginary screen outer peripheral line is calculated.

A technique for presenting display screens of a plurality terminals connected to a network on a multi-window screen of a display screen of a display device. A communication unit receives image data captured and then sent by each terminal having a screen capture function. A display control unit controls an image synthesizer to synthesize the captured image data into single screen multi-window format data. A multi-window screen is thus presented.

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.

In response to a requirement of transferring a file from a personal computer PC to a projectorthat is output by dragging and dropping a corresponding file icon onto a projector icon, a CPUrequires setting of a password. The CPUmaps the preset password to a file and transfers the file with the password to an external storage device of the projector. The projectorrequires 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.

Commands and data transferred via a network line NL are input to an ASP terminal portionvia a network interface controller. A first CPU loads a client application corresponding to the command and generated user interface image data via a graphics controller. A video signal conversion circuitreceives image data from the graphics controllerand transfers the processed image data to an LCD drive circuit. LCD drive circuitdrives an LCDin response to the received image data to project the desired image data onto a projection screen.

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.

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.
