摘要： A projector 100 projects an image onto a screen 200 by having light from a light source 111 pass through light valves 108˜110 corresponding to RGB colors and a projection lens 101. A special pattern is displayed on the light valves 108˜110 so that an image of the special pattern is projected onto the screen 200. The projector includes a half mirror 112 that directs light, which has been reflected back off this image on the screen 200 and back through the light valves 108˜110, toward the collective lens 113, and a light detecting element 114 for detecting the intensity of the light collected by the collective lens 113. Based on the detected intensity, the microcomputer 116 automatically adjusts the projection parameters of the projector 100.

摘要： A video projecting system includes two video projectors. Each video projector has a scaling processing circuit that generates a scaled video signal from an incoming video signal, the scaled video signal representing a partial image of a predetermined size, a luminance adjustment circuit that generates from the scaled video signal from the scaling processing circuit an adjusted video signal representing the partial image having a reduced luminance in a predetermined region of the partial image, and a display device that generates a partial image based on the adjusted video signal which is outputted from the luminance adjustment circuit. The partial image generated by the display device is projected via an optical system onto a screen, so that respective partial images partially overlap each other, thereby creating one stitched image. Thus, a compact and inexpensive video projecting system which can eliminate the need of manual readjustment of a plurality of video projectors is provided.

摘要： An image display device includes a plurality solid-state light sources, a modulator configured to modulate light from a plurality of solid-state light sources, and an image display device configured to generate from a frame of image data, a plurality of subframes each further divided into subfields, and to display the plurality of subframes. The modulator turns off light output from all the solid-state light sources for the duration of one or more of the plurality of subframes, whereby it is possible to reduce motion blur arising from a hold-type display device, in which after-images remain on the retina of a person's eyes when viewing moving objects.

摘要： A light modulation apparatus using a light source and a device for ON/OFF control an output light of the light source is provided. The apparatus is capable of increasing the number of gradations of light outputted from the device without increasing the frequency of a clock signal that serves as a unit for ON/OFF controlling the output light from the light source. A light intensity modulation circuit generates, based on a luminance signal YS and a synchronizing signal, an intensity modulating signal for output to a power supply, thereby causing a light source to output light intensity-modulated according to the luminance signal. A pulse-width modulation circuit generates, based on the luminance signal YS, the synchronizing signal, and the clock signal, a pulse-width modulating signal for output to a light valve, thereby causing the light valve to output light modulated in pulse width according to the luminance signal.

摘要： A control means individually turns each switching means on or off so that a current has a waveform which is approximate to a parabolic waveform and is appropriate for focusing current flows in a focusing coil, synchronizing with a horizontal sweep. When the focusing current increases, energy is transferred from the power source to the focusing coil. When the focusing current decreases, energy is returned from the focusing coil to the power source by a flywheel current. Thus, the focusing current is supplied with less consumption.
