Abstract: A CRT-matrix type big screen display system having self-emitting type picture cells is provided with a deflection waveform as a sawtooth waveform and a deflection waveform in the other direction as a step deflection waveform crossing the picture cells. Inclination of the scanning line is eliminated so that fluctuations in display brightness thereto are avoided and a satisfactory picture display is achieved. Also in CRT-matrix type big-screen display systems, index elements or cells are provided between sets of primary color cells and in the scanning direction. At least at the start of the scanning operation, the index elements or cells are scanned and the positional information thereof is stored in a memory for use in processing a video signal to achieve a satisfactory picture display. Furthermore, prior to reproducing a picture, a photo pickup equipment is slidably moved across the big screen and positional information of primary color cells sensed thereby is stored in a memory, which positional information is used in processing a video signal so that a satisfactory picture is displayed.

Abstract: A luminescent display cell comprising a glass envelope having a front panel, a side wall, and a rear plate. Plural luminescent display segments are formed on the front panel of the glass envelope, the display segments being supplied with an anode voltage. Plural cathodes are arranged on the rear panel side of the glass envelope in corresponding relation to the display segments. Plural control grid electrodes are arranged between the display segments and the cathodes in corresponding relation to the display segments. A common accelerating electrode is disposed between the display segments and the control grid electrodes. The voltage applied to each control grid electrode is controllable for electron emission from the cathodes so as to render each display segment corresponding to each control grid electrode selectively luminous for display. Furthermore, a separator surrounds each display segment and it is supplied with the above anode voltage so that diffusion lens is formed which allows the electron beam from the cathode to be spread laterally and radiated to the entire surface of the display segment to be rendered luminous.

Abstract: A solid-state video camera employing a plurality of image sensing means in the form of charge coupled device chips which are arranged in such a manner that the video image cast on respective chips are displaced by distance equal to tau H/N where tau H is the reciprocal of the image sampling frequency, also referred to as the alignment pitch of the picture elements in the horizontal direction and N is the number of charge coupled chips. After converting the images into electrical signals, read-out timings of given picture elements of respective chips are shifted in time in accordance with the shift in distance between the images on the respective chips prior to mixing the output signals. In this way a video output signal having a wide-band width is obtained. In addition, color video information is possible by the use of color filters which may be disposed in front of the respective charge coupled chips.
