A method for interfacing with a computer through a projected display of the computer using a laser pointer includes processing an image of the projected display captured by a camera, determining position of a laser pointer spot on the projected display, generating commands to position a computer mouse pointer at a screen position corresponding to the projected display, and generating a mouse click for the computer when a programmable laser pointer event occurs. Commands may be used to emulate control of the computer typically provided by a pointing device such as a mouse or track ball.

For reducing the effect of reverse half-occlusion in a 3D presentation on a screen, a virtual window is created in front of the screen. The screen is to be used for combining a left image and a right image for the 3D presentation. The virtual window is created by removing image data at a left edge of the left image and at a right edge of the right image before combining the left image and the right image on the screen.

Supporting a 3D presentation

The present invention provides a system including a stereoscopic endoscope having left and right image pickup units for picking up parallactic images of an object through objective lenses laterally arranged at a distance from each other and CCDs laterally arranged at a distance from each other. In the stereoscopic endoscope, the focal distance is variable by moving focusing lenses. A display control unit is constructed so as to mask image pickup areas in left and right images display in left and right display elements on the basis of information regarding the distance to an object, the image pickup areas being picked up-only by one of the left and right image pickup units. Thus, images corresponding to an area that is picked up in common by both the left and right image pickup units are displayed.

Stereoscopic-endoscope display control apparatus and stereoscopic endoscope system

An apparatus includes a stereoscopic display region calculator calculating a stereoscopic display region to reproduce a three-dimensional positional relationship in image data displayed on a stereoscopic display device, based on two-dimensional or three-dimensional image data, a position of a target of regard of a virtual camera set in processing of rendering the image data, and orientations of the light beams output from the stereoscopic display device. The apparatus also includes an image processor performing image processing on image data outside a region representing the outside of the stereoscopic display region calculated by the stereoscopic display region calculator. The image processing is different from image processing on image data inside a region representing the inside of the stereoscopic display region. The apparatus also includes an image generator generating stereoscopic display image data from the two-dimensional or three-dimensional image data after processed by the image processor.

PROBLEM TO BE SOLVED: To provide a projection type display device capable of enhancing the brightness of a projected picture when plural light sources are used in the device SOLUTION: A light source device 11 is mounted on this projection type display device This light source device 11 is provided with a prism 30 as a light synthesizing means and combines light beams from light sources 1a, 1b by making the light beam from the light source 1a to be made incident on the side 30a of one side forming the apex angle of the prism to be reflected on the side 30b of other side and by making it to be emitted from the bottom side 30c of the prism and, moreover, by making the light beam from the light source 1b to be made incident on the side 30b to be reflected on the side 30a of other side and by making it to be emitted from the bottom side 30c In this case, the prism 30 is made so that angles of incidence θ of the light beams with respect to perpendicular lines of respective sides 30a, 30b are set equal to or smaller than 20° and, moreover, the angle of incidence θ' of the light beam entering from the side 30a to the side 30b is set equal to or larger than the critical angle of about 418° due to the refractive index of the prism Thus, since the light beams of respective lamps 1a, 1b are totally reflected to be combined without loss, the brightness of the projected picture is enhanced COPYRIGHT: (C)2000,JPO

Projection type display device

PURPOSE: To eliminate or reduce the lack of stereoscopic expression for the front images shown at the parts around a display frame. CONSTITUTION: The virtual screen frames A and B are set in front of a monitor display frame 1 to prescribe the display ranges of the left and right eye front display media 2 and 3 respectively. Thus an observer can recognize a stereoscopic image in the depth directions of both frames A and B. As these frames A and B are separate from each other by an extent equal to a parallax set between both eyes, the medium 2 gets out of the frame A and lacks a screen like the medium 3 when this medium gets out of the frame 1. Thus an uneven lacking state is never caused between the right and left eyes and the satisfactory stereoscopic expression is always secured at the parts around the frame 1.

PROBLEM TO BE SOLVED: To prevent increase in man-hours due to increase in the adjustment man-hours, reduction in the productivity, and increase in the memory capacity for storing correction data. SOLUTION: The device is provided with a circuit 71 identifying plural scanning systems to as to identify the scanning system, and when number of displayed scanning lines differs on a screen depending on, e.g. the scanning system, a control microcomputer 66A obtains a position relation of an adjustment point based on a ratio of the scanning line number displayed on the screen in the mode and number of scanning lines dispalyed on the screen in the 2nd mode. Then digital filter is applied to convergence correction data in the 1st mode to calculate the convergence correction data in the 2nd mode and convergence correction data are automatically obtained from the convergence correction data in the 1st mode.

PROBLEM TO BE SOLVED: To provide a technique of detecting a reset defect of an HDMI (High-Definition Multimedia Interface) source device by an HDMI sync device. SOLUTION: An electronic device includes: an HDMI receiver for receiving TMDS (Transition Minimized Differential Signaling) signals from an external HDMI source device, detecting the presence/absence of a TMDS clock from the TMDS signals, and outputting the detection result; and a microcomputer for inputting the detection result outputted from the HDMI receiver, and determining the presence/absence of the TMDS clock from the inputted detection result. After switching to a connection with the HDMI source device, the electronic device functions as the HDMI sync device using the TMDS signals when the microcomputer determines that the inputted detection result is the presence of the TMDS clock, and does not function as the HDMI sync device when the microcomputer determines that the inputted detection result is the absence of the TMDS clock.
