Abstract: A projected image displaying apparatus for displaying bright three-dimensional images on a display screen. In one embodiment, images in three colors, each in the form of vertically oriented stripes, are projected onto a transmissive diffusion surface with the stripes of the three images interleaved with one another, and preferably slightly overlapping one another. A lenticular lens may be employed to direct the three dimensional image to the eyes of the viewer. In another embodiment, the two-dimensional images are projected in a form of three energy beams, which may be infrared, ultraviolet or visible light, onto a light-emitting layer composed of repeating sequences of first through third phosphor stripes, each corresponding to one of the primary colors.

Abstract: A radio bus system formed by combining a spread spectrum (SS) communication radio bus system with an electrical power line bus system using a spread spectrum modulated signal of the same signal format as that used in the radio bus system. An information signal transmission system is formed which transmits an information signal between a controller and a device which may or may not be connected to the electrical power line bus system, the information signal to be transmitted being converted into a spread spectrum modulated signal by an SS modem on a transmitter side and being succeedingly converted into a radio signal in a radio transmitter part of the transceiver section on the transmitter side for radiating the radio signal. The received radio signal is then converted on the receiver side into a spread spectrum modulated signal in a radio receiver part of the transceiver section and converted into the information signal by the SS modem on the receiver side for transmission through the electrical power line.

The light emitting coating is formed over a transmissive diffusion surface. A lenticular lens may be employed to direct the color image to the eyes of the viewer.

Abstract: In a stereoscopic television display device, the timing of read out data of a frame memory for right eye and the timing of read out data of a frame memory for left eye are shifted with respect to each other other so that the observer can freely select a point other than a camera's observation point as his observation point.

Abstract: In order to make a cathode-ray tube display a television picture for providing a copy thereof, as in a computer output device, a circuit substitutes dot-superposed signals for those portions of a television signal which provide half-tone areas of the picture. For a color television signal, the dot-superposed signals are derivable by storing the television signal for one field of frame and repeatedly reading the stored signal. The read-out signals are preferably emphasized at the subcarrier frequency. For a monochrome television signal, a signal is generated and inversed. For a generated signal of an even multiple of the horizontal scanning frequency, a phase-adjusted signal is produced by selecting either the generated signal in every other line period of the respective frames and the inversed signal in the remaining line periods or the generated and inversed signals in every other field and the remaining fields, respectively.

Abstract: Picture elements or light-sensitive elements of a solid-state area image sensor have associated color filter elements with three spectral sensitivity characteristics. The human eye requires a first of these colors to have a spectral sensitivity characteristic for producing a high level of visual resolution such as, for example, a green light of a luminance characteristic. The human eye does not require the second and third colors to have such a high resolution of a spectral sensitivity characteristic, such as, for example, a red or blue light, respectively. The green light-sensitive picture elements are arrayed at alternate picture element positions in every horizontal row and at alternate scanning line positions in every vertical column, in order to form a checkerboard pattern. The remaining picture elements are arrayed so that the interspaces between the green light-sensitive picture elements are alternately occupied in the successive scanning lines by the red and blue light sensitive picture elements.

Abstract: A solid state, color image pickup apparatus separates incident light into three light beams, which diverge in three directions, to form three separate images. Two solid state image pickup devices correspond to a first and a second of the three images formed by the separated light beams. The two object images are a luminance light or a green light image, each having a first spectro-characteristic requiring a high visible resolution. The two solid state image pickup devices receiving the first and second images are displaced away from each other, by a distance in a row direction corresponding to 1/2 of the distance between adjacent picture elements, as viewed in the row direction. A color filter is located at the position of a third object image. The color filter includes cyclically recurring optical filters having a second spectro-characteristic (a blue light characteristic). Neither of these characteristics requires a high visible resolution.

Abstract: An iris controls the amount of light transmitted through television camera lens to an integrated semiconductor matrix of light responsive elements. A characteristic of the matrix is that photo-charges may overflow the light responsive elements if the light falling on the matrix becomes too bright. The normal iris control responds to a loss of picture contrast caused by the overflow of charges and attempts to increase contrast by increasing the amount of light passing through the lens. The invention compares the output from the light responsive elements with a reference signal representing black areas in the picture. When the comparison exceeds a given difference, a special iris control overrides the normal iris control in order to reduce the amount of light passing through the lens. The reference signal may be taken from one or more of the light responsive elements which are shielded from light passing through the lens.

Abstract: Incident light is analyzed into a cyan light component, a yellow light component and a white light component covering spectrum characteristics of the cyan and yellow light components. The three light components are converted into electric signals by one or more image pick-up devices and the electric signals are separated into a cyan signal, a yellow signal and a white signal. A matrix circuit comprising color filters arranged in a predetermined pattern is provided for synthesizing the cyan, yellow and white signals into a luminance signal and two types of color difference signals.
