摘要： An apparatus and method are provided for use with a system including a digital data base for storing digitized images and digitized audio messages, for controlling concurrent reproduction of digitized images on an image reproduction device and audio information on a sound reproduction device. The digitized images are stored as image data files in the digital data base. Likewise, the digitized audio messages are stored as audio data files in the data base. Audio messages and images are associated with each other. This is accomplished by means of a presentation sequences file stored in the data base or in a separate EEPROM memory. In response to a user command, a controller causes image data and audio data for a selected image and an accompanying audio message to be read from the data base. The respective data are provided to the image reproduction device and the sound reproduction device, respectively, whereby the audio message is played back by the sound reproduction device as the image is displayed on the image reproduction device. A controller maintains the display of the image for the duration of the audio message. The controller reads a sequence of images and audio messages from the data base and displays each image and plays back one or more associated audio messages in turn.

摘要： A video input signal is amplified and applied to the cathode of a kinescope via linear kinescope driver amplifier provided with an output impedance sufficiently high to impart gamma correction to images displayed by the kinescope but tending to diminish the bandwidth of the amplified video signal applied to the cathode. A capacitor is included in the driver for restoring the bandwidth of the amplified video signal. For stabilizing the high frequency response (detail) of displayed images the value of the capacitor is varied as a function of the brightness of displayed images.

摘要： A circuit arrangement for adaptive white-compression of video signals of a color television apparatus, particularly of a HDTV picture signal generator, which has a signal minimum detector circuit (4, 5, 6) in each color channel. Input color signals (R, G, B) as well as a compressed color signal are applied to these detector circuits, while the smaller of the two input signals can be derived from their outputs. The compressed color signals are generated by digitally controlled multiplier circuits (14, 15, 16). The digital control signal for these multiplier circuits is generated by controlling an up/down counter (24) by a digitized steering signal derived from the video output signals by line-sequential measurement and comparison with a threshold value reference signal.

摘要： A video signal in component form is processed by generating high frequency linear color component signals from wideband linear color component input signals. The high frequency linear color component signals are combined to produce a high frequency linear luminance component signal, which is combined with color component signals that contain low frequency components present in the wideband linear color component input signals to produce high-frequency-corrected linear color component signals.

摘要： A digital signal is non-linearly processed without generation of alias components by modelling the required non-linear operation by the best available quadratic function. A transformation circuit for implementing the quadratic function ax.sup.2 +bx may be used. As a result, only the second harmonic of each original frequency component of the digital signal is generated. Space for accommodating the original frequency components and the second harmonics can be made either by sampling frequency up-conversion in an interpolation up-converting circuit which doubles the sampling frequency, or by bandlimiting the original digital signal to a quarter of the original sampling frequency. In either case, the second harmonics occur below the Nyquist limit and no alias components are generated. A video signal color corrector makes use of both of the above techniques.

摘要： A detection circuit for detecting a color temperature of the ambient light of an object is provided in a video camera. A .gamma.-correction circuit for subjecting a luminance signal Y obtained by processing an output signal of a solid-state imaging device to .gamma.-correction with a fixed gamma coefficient changes the correction level of the luminance signal Y in accordance with the fluctuation of the color temperature detected by the detection circuit. As a result, it is prevented that in a low color temperature, a red portion of a reproduced image becomes abnormally bright. Further, there is provided an illuminance detection circuit. In a low illuminance, the correction level of the .gamma.-correction circuit is reduced to prevent mixture of the noise.

摘要： Disclosed herein is a method for processing a first picture to be reproduced on a color picture tube. The value e.sub.ys of luminance signal for a shadow S of a second picture, which has been obtained from a preceding scanning operation, is subtracted from the value e.sub.y of luminance signal for a desired pixel P out of video signals received, thereby determining the value e.sub.p of a base luminance signal. Luminance signal values e.sub.s and e.sub.h are set respectively for a shadow S and a highlight H among pixels of the first picture to be reproduced on the color picture tube. The value e.sub.q of a luminance signal for a pixel Q, which corresponds to the pixel P and is to be reproduced, is determined from the signal values e.sub.p, e.sub.s and e.sub.h in accordance with a particular correction formula. The luminance of each pixel, which is to be reproduced on the color picture tube, is adjusted in accordance with the value e.sub.q of the corresponding luminance signal thus determined. A picture signal processor suitable for use in the practice of the method is also disclosed.

摘要： The high frequencies of the red, blue and green color television signals, with appropriate individual gain levels, are combined in a mixer having non-additive and additive characteristics, with the standard high frequency luminance signal to obtain a correction signal that is the greatest of the four when all have the same polarity, or in the event any of the four signals has opposite polarity with the others a correction signal that is equal to a linear combination of the two opposite polarity, highest level signals. This correction signal is used to compensate for the violation of the constant luminance principle of a luminance signal that was generated by linear matrixing of gamma corrected color signals. The compensation signal is combined with the luminance signal using a mixer similar to that used to generate the correction signal.
