摘要： In a light-responsive semiconductor device in which the laser oscillation state is controlled by incident light, a layer of material having a conductivity modulatable by light is integrated in a semiconductor laser structure and is responsive to the incident light for the control of the laser oscillation state of the device. In one embodiment constituting a light logic element, a plurality of semiconductor lasers are integrated on a substrate with each respective semiconductor laser having a grating along the entirety or a portion thereof and provided with a light waveguide connecting with a waveguide of an adjacent semiconductor laser. In a bistable semiconductor laser there are provided two different conductivity type light confinement layers, an active layer comprising a multiple quantum well structure which is between the two light confinement layers, a grating provided close to the quantum well active layer. The oscillation wavelength established by the grating is shorter than the peak gain wavelength produced by the quantum well active layer.

摘要： An optical logic element includes an optical bistable npnp element for switching from a high resistance state to a low resistance state in response to electrical bias and incident light energy in which the switching time becomes shorter as the incident light energy becomes larger. The elements emit light in the low resistance on state. The optical logic element is designed for analog threshold processing of light energy. A plurality of optical bistable elements connected in parallel differentially threshold process incident light energy. An opto-electronic conversion apparatus includes linear arrays of light emitting elements, a two-dimensional array of optical memories, i.e., optical bistable elements, and linear light receiving element arrays arranged transverse to the light emitting element arrays, all integrated with each other. Corresponding light emitting elements, optical memories, and light receiving elements permit arbitrary transfers of signals. Periodic refresh light pulses maintain each optical memory in an established state.

摘要： An optical neural network which imitates a biological neural network, to provide an associative and/or pattern recognition function, is made of light emitting elements to represent an input neuron state vector, a correlation matrix which modulates light according to stored vector information, light receiving elements, an accumulator and a comparator to perform a threshold function. A stored vector closest to an input vector can be found from a large amount of information without increasing the system size by dividing the correlation matrix and the input neuron state vector with time division techniques, frequency modulation or phase modulation techniques. Positive and negative valves can also be provided with similar techniques.

摘要： A video display apparatus generates luminance information for individual frames of a video signal from histograms of the luminance component of the video signal, and classifies the content of the video signal on the basis of this information. Color saturation information is also generated from color saturation histograms, and scene changes are detected. Video correction parameters and display control parameters are derived from the content classification and color saturation information. The video signal is corrected according to the video correction parameters, and displayed according to the display control parameters. Display characteristics suitable for the video content are thereby obtained. The parameters are changed when a scene change is detected, so that the viewer is not disturbed by the change in video display characteristics.

摘要： An information retrieval system allowing the user to build a database or to retrieve data therefrom based on vague retrieval-designating data without becoming aware of the database structure. The system comprises a neural network, a memory, an interface part and a CRT. The neural network stores data designating electronic still pictures contained in the memory. When data for designating retrieval are input, the interface part groups the data into such categories as the place where the desired picture was taken and the date on which it was taken, and supplies the neural network with the categorized input data. In turn, the neural network outputs by association the data corresponding to the input data. Given the data from the network, the memory outputs the relevant electronic still picture to the CRT for display.
