摘要： A video display system that includes a housing has arranged thereon a plurality of video input terminals for receiving a plurality of video signals having different scanning frequencies. An expansion/compression processing circuit replaceably mounted on the housing receives and expands/compresses the plurality of video signals and produces at least one video signal expanded/compressed in synchronism with a sync signal selected by a sync switching circuit. At least one of the video signals is synthesized with another video signal, and the synthesized video signal is produced by a video signal synthesis circuit. A video signal from the video signal synthesis circuit is used to generate a video display signal in synchronism with the sync signal. This video display signal is applied to a display. At least one such video display system, an AV controller, a central control console and a lecture table are combined to realize a screen display system.

摘要： In order to enable sampling of high definition still video signals in addition to common video signals, a function is added for sampling video signals with every other plurality of picture elements as an interval to an image processing apparatus without using a sampling circuit which requires high speed operations. The invention is also intended to change over between two circuits that is, a circuit for using a picture element clock regenerated by a PLL circuit as a sampling clock for analog to digital converters and a circuit for using a clock obtained by dividing the picture element clock as a sampling clock for the analog to digital converters to sample video signals with every other plurality of picture elements as an interval. Thus, it is possible to carry out sampling of high definition video signals with high frequencies in addition to common video signals without necessity of raising the operating speed of the sampling circuit.

A liquid lens formed by sealing a liquid in a space between opposite transparent members is disposed near the light source or the real image of the light source to enhance the relative corner illuminance without reducing the light capturing efficiency by multiplying the angle of divergence of light rays emitted by the light source by the reciprocal of the refractive index of the liquid. A first optical system disposed on the entrance side of the liquid crystal panel is provided with a relative corner illuminance enhancing means comprising a first light converging means disposed relatively near to the light source means, and a second light converging means disposed relatively remote from the light source means. The first light converging means enhances the relative corner illuminance on the entrance surface of the second light converging means.

摘要： A CRT display device capable of displaying a signal from the existing image signal source, in which a vertical frequency is approximately fixed and a horizontal frequency is widely distributed beyond a ratio of 3:1, on one image screen. The CRT display device includes a scan converter unit and a display unit. The scan converter unit includes an output horizontal frequency unifying circuit, a horizontal blanking period ratio converting circuit, a vertical frequency converting unit and a vertical blanking period ratio converting circuit. The display unit includes a vertical deflection circuit and a circuit for correcting a vertical S-shaped distortion. In a phase synchronous circuit, a lock-out detector is connected to an output of a three state output digital phase detector, and on the basis of an output thereof, a switch is subjected to the "ON"/"OFF" control. For a period of time when an output of the lock-out detector indicates a lock-out state, a loop gain of the PLL is increased and the pull-in time is shortened. For the remaining periods of time, i.e., in the steady state, the loop gain is decreased and the noise resistance characteristics are improved.

摘要： A cathode ray tube display in which a signal for detection of a cathode current is inserted into a part of the vertical blanking period of the video signal to be displayed, a cathode current corresponding to the signal for detection is detected, and a cathode voltage or a grid voltage is negative feedback controlled so that the detected cathode current becomes constant, thereby stabilizing the cathode current. The display has a local overscan circuit for executing a vertical scan on the screen with a width larger than a predetermined scan width only at a timing of the cathode current detecting signal inserted for a vertical blanking period, and even in the case where an underscan system to scan by a width smaller than a predetermined display screen width is used as a scan system of the screen display. The invention prevents a harmful visible display image by the cathode current detecting signal appears on the screen.
