Abstract: A flat screen autostereoscopic display for bright wide angle stereoscopic images employs a flat screen on which are displayed a plurality of regularly spaced discrete, finite light emitting sites such as thin, vertical light emitting lines. A light valve located in front of the screen forms images by means of varying the transparency of individual pixels arranged in a raster pattern across its surface. A mask in front of the light valve completes the display unit to enhance the parallax effect obtained by the viewer. The screen and light valve are arranged in such a way that an observer sees the light emitting lines through one set of pixels with the left eye and the same lines through a different set of pixels with the right eye. The autostereoscopic effect is obtained when the viewer sees with the right eye and the left eye either alternating rows or alternating columns of pixels.

Abstract: A color hard copy apparatus converts an analog video signal of a still picture frame displayed on a color graphic display into binary video data to obtain a multicolor gradation picture. A single analog-to-digital converter samples the analog video signal a plurality of times at respectively different threshold levels, each threshold level being maintained constant during the sampling of the entire picture frame, to convert the analog video signal into corresponding binary video data. The binary video data are written in a picture memory at predetermined write-in addresses according to a predetermined multicolor gradation picture program, such as an organized dither program or a density pattern, and the binary video data are read out of the picture memory according to the predetermined multicolor gradation picture program to obtain binary picture data signals for use in printing a high-quality multicolor gradation picture corresponding to the desired picture frame displayed on the color graphic display.

Abstract: An image sensor having means for reducing fixed-pattern noise in its output signal. Real and dummy output lines are provided. First and second sets of transistors, driven by the horizontal shift register, couple, respectively, outputs of the sensor array and a floating line onto the real and dummy lines at read-out time. Because the fixed-pattern noise signal on the real and on the dummy lines is the same, the differential voltage between the two lines is entirely due to the actual signal. A flip-flop circuit is connected between the real and dummy lines to sense and amplify the differential voltage.

Abstract: A secondary video signal is sampled, digitized and combined with an in-memory switching signal. The combined digital signal is stored in a random access video memory. The stored signal is read out in synchronism with the synchronizing signal components of a primary video signal. The switching signal is recovered from the output of the memory, and compared with a content code signal to develop a fast switching signal. A video output switch, coupled to receive the primary video signal and the stored secondary video signal and responsive to the fast switching signal, applies an appropriate one of the two input signals to the kinescope to define a secondary inset picture within a large primary picture.

Abstract: A photoelectric transducer receives the light reflected from an original, and outputs color signals representing cyan, green, and yellow. These colors signals are processed by a signal-splitting circuit and a signal-converting circuit, and are thereby converted to image-forming signals representing yellow, magenta, cyan, and black. When a print key of a control panel is depressed, a main control section instructs the signal-converting circuit to continuously output the image-forming signals. In accordance with the output image-forming signals, images are continuously formed on a plastic film, by using an ink ribbon. Hence, a yellow image, a magenta image, a cyan image and a black image can be formed on four plastic films, respectively. These plastic films can be used in making plates to print a multicolor image.

Abstract: A method of forming an electric signal wherein the signal level corresponding to the selected color in the original indicates the maximum or minimum value. The original is exposed to the light and the reflected light is introduced into a photoelectric converting means through two different paths, each of which has a filter corresponding to a different selected color. These two signals are multiplied by a predetermined ratio, and are combined to obtain the final image signal.

Abstract: A color balance circuit for a video camera bases red and blue gain adjustments on the ratios of red and blue light to green light in the scene. Before sequentially integrating red, green and blue light for the color balance calculation, certain process parameters are prescaled for the level of scene illumination. In particular, the integration reference voltage and the clock frequency of the time base (timing the integration) are scaled according to the level of green light so that subsequent integration of expected light levels yields results in the midrange capacity of the integrator.

Abstract: A video signal synthesizer for producing a picture-in-picture effect on a display device utilizes a phase locked loop circuit to generate a carrier wave synchronized with a color burst signal of a composite video signal representing a main picture to be reproduced, which carrier wave is used to modulate a time compressed second composite signal which represents a sub-picture to be superimposed on the main picture. A time division multiplexer is used to multiplex the first and time compressed second video signals to produce a picture-within-a-picture video signal for application to the receiver of a display device. By using a carrier wave generated from a phase locked loop circuit, the color subcarrier signals of both the main and sub-picture signals have the identical frequency.

Abstract: The read out of a signal from an imaging device is conducted during a voltage read out mode, and resetting of a signal output line is carried out each time a signal of a plurality of pixels is read out. Signal charge is accumulated on the signal output line, and is then read out. The accumulated signal is differenced or differentiated at a later stage to reproduce an original signal.

Abstract: In an imager, an image sensor has a pn junction at which positive and negative carriers are created in accordance with a quantity of light incident to the pn junction. One type of the positive and negative carriers is read out as an image signal and as soon as the other type is created, it is delivered out of the image sensor. A photometric circuit connected to the image sensor calculates a quantity of the incident light on the basis of the other type of carriers delivered from the image sensor and generates an incident light quantity signal. In accordance with the incident light quantity signal, an incident light quantity adjusting signal generator and an incident light quantity adjuster adjust the quantity of the light incident to the image sensor to an optimum value to thereby obtain proper exposure.

Abstract: A projection color television system having an improved resolution and luminance comprises red, green and blue color emitting tubes, the electron beams of which are focused onto their respective screens. In order to compensate for the strong saturation of the blue phosphor, and simultaneously to take advantage of the relatively fast decay of this phosphor, the blue color emitting tube is a single gun, multispot display tube. The increase in light output obtainable from the blue color emitting tube is matched by providing interference filters in the red and green color emitting display tubes and optionally in all three red, green and blue emitting tubes.

Abstract: A video still camera includes a common integrating circuit for measuring light level in relation to both color balance and exposure control. An exposure photodiode generates an exposure signal from a small sample of image light diverted from the optical section of the camera. Broadly oriented red, green and blue photodiodes generate three color balance signals corresponding to the color characteristics of the illuminant. The photodiodes are selectively multiplexed into the input of the integrating circuit for the measurements. In one embodiment, the exposure photodiode remains connected to the integrating circuit for exposure measurement. The color balance measurement is unaffected because the small photocurrent from the exposure photodiode is effectively swamped by the much larger color photocurrent from a multiplexed color photodiode.

Abstract: An apparatus interpolates color-difference line-sequential signals appearing alternately in a video signal together with a luminance signal. The video signal is received by an input circuit and then held temporarily and on a horizontal scanning line basis by a hold circuit. Each of the color-difference signals is interpolated by an interpolating circuit by producing an arithmetic mean of the color-difference data of the video signal being held by the hold circuit and color-difference data of the video signal being received by the input circuit, on the basis of the pixels corresponding to each other on horizontal scanning lines.
