Abstract: An optical scanning apparatus in which keystone distortion non-linearity distortion in a projected image can be excellently corrected is provided. An optical scanning apparatus has light source means and deflecting means for deflecting a light beam emitted from the light source means two-dimensionally in a first direction and a second directrion, the deflection speed of the deflecting means being higher in the first direction than in the second direction. The deflecting means is driven in such a way that its angular velocity in the second direction is smaller when optically scanning a position on the surface to be scanned at which the angle of incidence of the deflected light beam in the second direction is larger than when optically scanning a position on said surface to be scanned at which the angle of incidence of the deflected light beam in said second direction is small.

Abstract: An image display apparatus connected in a communication-enable manner to an information processing unit for processing image data and outputting an image signal, wherein the image display apparatus receives the image signal and displays an image. The image display apparatus comprises an on-screen display generating unit for generating the image, a coordinate input unit for providing position information based on pointing on a display screen, and a control unit for controlling the on-screen display generating unit to generate and display a scroll bar, and controlling the image signal output from the information processing unit in accordance with an input for an area of the scroll bar from the coordinate input unit.

Abstract: In an information processing apparatus which is connected to an external terminal having an input unit via a network, can receive an input from the input unit of the external terminal, and has its own input unit, an exclusion manager (23) monitors an input from the input unit of the external terminal and that from the self input unit. As a result of monitoring, if an input from a given input unit is generated, the exclusion manager executes exclusion control that inhibits an input from the other input unit until that input is completed.

Abstract: In a multidisplay system, an image is displayed without necessitating a display control signal supplied from an external device. Each image display device in the multidisplay system includes an interface for receiving image data and transferring the image data to an image display device at a downstream location. Each image display device also includes a DDC (Display Data Channel) communication processor and a rewritable memory for storing EDID (Extended Display Identification Data) information. When another image display device is connected at a downstream location, EDID information is acquired from the connected image display device via the DDC communication processor, and display resolution information and interconnection information are set. In particular, the display resolution described in the EDID information is rewritten by the display resolution information set in the above process.

Abstract: To easily and optimally display data output from plural connected information terminals on a display device based on display attribute information given with respect to each output data, an information processing device, which calculates similarity of different image data and can connect the different image data to one display device and two or more information terminals, is characterized by comprising a data acquisition unit to acquire the data output from the information terminal, a display attribute information acquisition unit to acquire the display attribute information corresponding to the output data acquired by the data acquisition unit, an update unit to update the display attribute information acquired by the display attribute information acquisition unit, and a display control unit to control the display of the output data on the display device based on the relevant display attribute information.

Abstract: There are provided an image display apparatus and method, which are capable of improving the operability of a white board function thereof, and allowing different devices to be operated on the same screen in a unified manner, and an information processing apparatus having the image display apparatus, and a storage medium storing a program for implementing the method. A control signal input device inputs a control signal. An operation signal output device outputs an operation signal to an external signal source. A memory section stores display screen information. A control signal switching section selectively switches use of the control signal from the control signal input device between a control signal for the display screen information stored in the memory device and the operation signal to be outputted from said operation signal output device.

Abstract: The present invention provides a projection apparatus utilizing plural light sources, in which the light source principally irradiating the light valve is switched by moving the relative position between the plural light sources and the mirror for guiding the lights outputted from such light source to the light valve. Also the configuration can be simplified by using commonly the light condensing device for the plural light sources.

Abstract: According to the present invention, a process for coordinate data entered by a currently used coordinate input device is automatically performed first, without a special mode setting operation being required. First, a mouse driver is initialized, and then, a check is performed to determine whether a button on a digitizer is depressed. When the button on the digitizer is depressed, a corresponding process is performed, and the mouse driver is returned to the initial state after a predetermined time has elapsed. When a button on a mouse is depressed, a corresponding process is performed, and the mouse driver is returned to the initial state after a predetermined time has elapsed.
